1979 Vehicle Tire Fitment Guide

Rim Diameter: 15 in  ·  Sidewalls: RWL, Blackwall, Narrow Whitewall, Wide Whitewall, Pin-White-Stripe, Redline

The 225/70R15 size serves a mix of 1979 performance and luxury applications, including the 1979 Aston Martin V8, 1979 Chevrolet Camaro, 1979 Chevrolet Corvette, 1979 Chrysler New Yorker, and 1979 Pontiac Firebird. It bridges sporty proportions and substantial load capacity, and current products show that flexibility. Available choices include blackwall Michelin XWX, RWL offerings from Goodyear and Cooper, and published rim-width guidance ranging from 6.0 to 8.0 inches depending on the tire. This makes it a key fitment for owners balancing appearance, handling character, and wheel compatibility.

Rim Diameter: 15 in  ·  Sidewalls: RWL, Blackwall, Redline, Wide Whitewall, Narrow Whitewall

Found on the 1979 Aston Martin V8 and on 1979 Rolls Royce Camargue and Corniche applications, 235/70R15 is a large-format radial suited to heavy grand touring and luxury cars. It combines a broad section width with a relatively tall profile, giving these cars the substantial footprint expected of high-end late-1970s machines. Product offerings include blackwall touring-style tires from Avon and Michelin, an RWL Cooper Cobra Radial G/T, and a redline BFGoodrich Silvertown Radial. Published rim-width ranges on several options help when checking wheel compatibility on restored or previously modified vehicles.

Rim Diameter: 15 in  ·  Sidewalls: OWL, RWL

This wide radial size is associated here specifically with the 1979 Aston Martin V8, making it one of the more aggressive low-profile performance fitments in the 1979 range. Compared with taller 70-series tires, 255/60R15 gives a broader stance and a distinctly sporting late-1970s appearance. Available products emphasize blackwall and raised-letter styles, including Goodyear OWL options plus RWL choices from Cooper and BFGoodrich. Published rim-width ranges extend from 7.0 to 9.0 inches on some products, so wheel width should be verified carefully before selecting a replacement tire.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

The 155R13 size is one of the most widely shared small-car radial fitments for 1979, appearing on vehicles such as the 1979 Audi Fox, 1979 Honda Civic, 1979 Mazda GLC, 1979 Toyota Corolla, 1979 Triumph Spitfire, and several others. This narrow 13-inch metric radial is typical of economical imports and lightweight compacts from the period. Current product choices are blackwall only, with Michelin XAS-FF and Dunlop SP Sport Aquajet offerings. That keeps the focus on period-style radial construction and compact-car proportions rather than decorative sidewall treatments.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

175/70R13 is a shared 1979 radial size used on a number of compact imports and sporty small cars, including the 1979 Honda Prelude, 1979 Nissan 200, 1979 Plymouth Champ, and 1979 Volkswagen Scirocco. Compared with taller 80-series radials, this lower-profile size gives a more modern late-1970s handling-oriented look. The listed product selection centers on a blackwall Avon CR6ZZ with a published 4.5- to 6.0-inch rim width range, making it especially relevant for owners of smaller European and Japanese cars looking for a performance-leaning replacement within the original size family.

Rim Diameter: 13 in  ·  Sidewalls: Redline, Blackwall, Wide Whitewall

Used on cars such as the 1979 BMW 320i & 320iA, 1979 Dodge Omni, 1979 Lotus Elite, 1979 Toyota Corolla, 1979 Triumph TR7, and 1979 Triumph TR8, 185/70R13 is a versatile compact performance radial size. It represents a step up in width from smaller economy-car fitments while retaining a modest 13-inch wheel diameter. Product choices include blackwall sport options from Avon and Dunlop, along with BFGoodrich Silvertown Radial versions in redline and wide whitewall form. That range allows owners to tailor the visual character of the tire without leaving the correct size category.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

The 195/70R14 size fits a focused group of 1979 sporty coupes and sedans, including the 1979 BMW 633 CSi & CSiA, 1979 Dodge Challenger, 1979 Mercedes-Benz 300, 1979 Nissan 280ZX, and 1979 Plymouth Sapporo. This radial format combines moderate width with a shorter sidewall than traditional 80-series tires, giving a more contemporary driving and visual feel for the period. The listed product choice is a Dunlop Sport Classic blackwall radial, which suits owners looking to preserve a late-1970s European or import performance appearance rather than adding whitewall styling.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, RWL, Dual-Redline, Redline, Blackwall

205/70R14 is a widely used late-1970s radial size that appears on vehicles ranging from the 1979 BMW 733i and 1979 Ferrari 308 to the 1979 Buick Regal, 1979 Chevrolet Monte Carlo, 1979 Oldsmobile Cutlass, and 1979 Toyota Pickup. Its breadth across imported performance cars and domestic personal cars makes product choice especially important. Available tires include narrow whitewall, RWL, redline, and dual-redline treatments, with published rim-width ranges on several options. This size offers room to choose between a sportier look and a more traditional period-inspired sidewall style.

Rim Diameter: 390mm in  ·  Sidewalls: Blackwall

220/55R390 is a metric-millimeter performance radial fitment used here on the 1979 BMW 733i. Unlike standard inch-based wheel diameters, the 390 designation belongs to Michelin’s TRX system, so it requires the correct matching wheel format rather than a conventional 15-inch or 16-inch rim. The listed Michelin TRX-B product includes a 390mm rim diameter and specific metric rim-width guidance, reinforcing how specialized this fitment is. For a 1979 BMW with this size, confirming whether the car still retains its TRX wheels is one of the first and most important fitment checks.

HR70-15 is a radial fitment used on premium 1979 luxury applications including the 1979 Bentley T2 Series, 1979 Ford LTD II, and 1979 Rolls Royce Silver Shadow. This size reflects the period’s alphanumeric radial convention, combining luxury-car proportions with a substantial 15-inch fitment. No product details are listed here, so owners should pay close attention to wheel size, tire type, and overall stance when replacing tires. Because this size spans both domestic and European luxury cars, the correct choice depends on the specific vehicle and whether it remains in its original wheel configuration.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

This radial size is used on several mid-size 1979 domestic cars, including the 1979 Buick Century, 1979 Chevrolet Malibu, 1979 Oldsmobile Cutlass, 1979 Pontiac Grand LeMans, and 1979 Pontiac LeMans. The 75-series profile gives a taller look than lower-profile sport sizes, making it a natural fit for everyday passenger-car applications of the era. Available products are all whitewall radials, with narrow whitewall choices from Tornel, Maxxis, and Travelstar. Published load ratings and rim-width information on several tires help owners match a replacement to both the vehicle’s character and the wheel in use.

GR78-15 is one of the most widely shared 1979 radial sizes, appearing across full-size domestic cars, vans, pickups, and wagons from makes including Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Mercury, Oldsmobile, Plymouth, Pontiac, and Nissan. This broad usage reflects how common alphanumeric radial sizing remained on larger American vehicles in 1979. Product details are not listed here, but fitment context matters because the same size appears on very different vehicle types. A full-size sedan, van, or pickup may all use GR78-15 while needing careful attention to wheel, load, and configuration differences.

Shared by a large cross-section of 1979 domestic full-size cars, wagons, utility vehicles, and trucks, HR78-15 covers applications as diverse as Cadillac luxury cars, Chevrolet and GMC trucks, Dodge utility vehicles, and Pontiac wagons. It is an alphanumeric radial size that sits squarely in the transitional late-1970s fitment landscape. Product specifics are not listed here, but because the same nominal size spans passenger and utility uses, owners should not assume every HR78-15 application needs the same type of tire. Matching the tire to the vehicle’s actual duty, wheel, and configuration remains especially important with this size.

FR78-15 appears on a mix of 1979 domestic coupes, sedans, vans, and utility vehicles, including the 1979 Chrysler LeBaron, 1979 Dodge Diplomat, 1979 Pontiac Firebird, and several Chevrolet, GMC, and Plymouth applications. This alphanumeric radial format was widely used on late-1970s American vehicles and can represent very different visual and functional needs depending on the model. No specific product details are listed here, so the useful takeaway is to verify the exact vehicle application rather than shop by size alone, especially when comparing sporty passenger cars with heavier multipurpose platforms.

Rim Diameter: 15 in  ·  Sidewalls: Pin-White-Stripe, RWL

GR70-15 is used on the 1979 Buick LeSabre, 1979 Buick Riviera, and 1979 Ford LTD, placing it firmly in the realm of larger late-1970s personal luxury and full-size cars. The lower 70-series profile gives a broader, more contemporary look than taller 78-series alternatives. Available products are all radial constructions with a bias-look appearance, including Goodyear choices in RWL and pin-white-stripe styles. That makes this size especially appealing for owners who want the visual flavor of period alphanumeric tires while still selecting a modern radial-type product within the listed offerings.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Goldline, Narrow Whitewall, Redline

The 205/75R15 size serves several substantial 1979 American cars, including the 1979 Buick Riviera, 1979 Cadillac Eldorado, 1979 Chrysler New Yorker, 1979 Chrysler Newport, 1979 Dodge St Regis, and 1979 Oldsmobile Toronado. This is a mainstream full-size radial with a tall sidewall and strong emphasis on comfort and classic proportions. Product choices include wide whitewall, narrow whitewall, and goldline styles from BFGoodrich, Tornel, and American Classic. Published rim-width ranges on several options help owners select a tire that suits both a luxury-car appearance and the wheel already on the vehicle.

BR70-13 appears on a group of compact sporty domestic models such as the 1979 Buick Skyhawk, 1979 Chevrolet Monza, 1979 Ford Pinto, 1979 Mercury Bobcat, 1979 Oldsmobile Starfire, and 1979 Pontiac Sunbird. This alphanumeric radial format captures the late-1970s shift toward lower-profile small-car tires. No product details are listed here, but the fitment itself suggests a more performance-oriented stance than the taller bias-ply alternatives often found within the same model families. Careful confirmation matters because several of these cars were offered with multiple tire sizes depending on engine, trim, and wheel package.

Used on 1979 compact domestic models including the 1979 Buick Skyhawk, 1979 Ford Pinto, 1979 Mercury Bobcat, 1979 Oldsmobile Starfire, and 1979 Pontiac Sunbird, BR78-13 is an alphanumeric radial size with a taller profile than BR70-13. That difference can affect stance and appearance even within the same basic vehicle family. Product details are not listed here, so the main fitment point is to verify which of the 13-inch options belongs on the exact model and trim. This is especially important on late-1970s compacts that could be equipped with both bias-ply and radial alternatives.

B78-13 is a bias-ply fitment used on several 1979 compact domestic cars, including the 1979 Buick Skyhawk, 1979 Chevrolet Monza, 1979 Ford Mustang II, 1979 Mercury Capri, 1979 Oldsmobile Starfire, and 1979 Pontiac Sunbird. This size reflects a more traditional small-car tire format than the radial alternatives also seen on many of these platforms. Product details are not listed here, but owners researching this fitment should note that the same model line may also appear with BR78-13 or BR70-13 radial sizing, making exact trim and wheel confirmation especially important before ordering.

Rim Diameter: 14 in  ·  Sidewalls: Wide Whitewall, Blackwall

The E78-14 size is used on a variety of 1979 compact and light-duty applications, including the 1979 Buick Skylark, 1979 Chevrolet Luv Pickup, 1979 Chevrolet Nova, 1979 Nissan Pickup, 1979 Oldsmobile Omega, 1979 Pontiac Phoenix, and 1979 Toyota Pickup. This is a bias-ply alphanumeric size, and current products show a split between passenger-car whitewall styling and utility-focused blackwall truck patterns. Available choices include a Coker Classic wide whitewall plus blackwall STA Traxion and STA Transport Highway tires, so intended vehicle use matters when selecting within this size.

ER78-14 is a radial size found on several 1979 domestic compacts and light trucks, including the 1979 Buick Skylark, 1979 Dodge Aspen, 1979 Ford Granada, 1979 Oldsmobile Omega, 1979 Pontiac Phoenix, and 1979 Toyota Pickup. It reflects the common late-1970s practice of using lettered radial sizing on family cars while also appearing on utility applications. Product details are not listed here, but the spread of vehicles shows why buyers should look beyond the size alone. A compact sedan and a small pickup may share ER78-14 while calling for different priorities in ride, appearance, and load use.

Rim Diameter: 15 in  ·  Sidewalls: RBL, Narrow Whitewall, Wide Whitewall

This radial size is associated with the 1979 Checker Marathon & Taxi, a vehicle known for substantial passenger and service-duty demands. The available product range reflects that broad utility, with whitewall options from Coker Classic, BFGoodrich, and Tornel as well as a BFGoodrich All-Terrain T/A KO2 in black sidewall form. Published load capacities reach into the mid-1700-pound range and beyond depending on the product, which is useful when evaluating a heavier sedan application. For a 1979 Checker, sidewall style and intended road use can both shape the right product choice within this size.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall

225/75R15 is shared by several 1979 utility-oriented vehicles, including the 1979 Checker Marathon & Taxi, 1979 International Scout II, 1979 Jeep CJ5 & CJ7, 1979 Jeep Cherokee, and 1979 Jeep Truck J-10. This radial size combines a tall sidewall with a larger section width, making it suitable for heavier, more rugged applications than many passenger-car sizes. Product choices emphasize classic whitewall treatments from BFGoodrich, Coker Classic, and American Classic, with published load capacities and rim-width ranges on several options. Owners should confirm wheel and vehicle use carefully, especially on restored four-wheel-drive models.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

The 700-15 size is a classic bias-ply fitment found on many 1979 trucks and utilities, including the 1979 Chevrolet Blazer, 1979 Chevrolet C/K Pickup, 1979 Dodge D150 Pickup, 1979 Ford Bronco, 1979 Ford F-100, 1979 GMC Jimmy, and 1979 Plymouth Trailduster. Current product offerings include both passenger-style wide whitewall and blackwall choices from Firestone and BFGoodrich, plus utility-minded blackwall STA Traxion products. Published rim-width guidance of 5.00 to 5.50 inches on several options is useful, but owners should still confirm wheel type and intended duty before selecting a replacement.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

H78-15 is a bias-ply size shared across a wide set of 1979 trucks, vans, wagons, and utility vehicles, including Chevrolet, Dodge, Ford, GMC, International, Jeep Truck, Plymouth, and Toyota applications. This alphanumeric format was common on heavier American vehicles and can indicate a different feel and appearance than similarly sized radial alternatives. Available products include wide whitewall Coker Classic tires and blackwall STA Traxion choices, with published load capacities around the upper-1700- to 1800-pound range on listed examples. The best selection depends on whether the vehicle is restoration-focused, work-oriented, or somewhere in between.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, Wide Whitewall, Narrow Whitewall, Dual-White-Stripe

Used on a large number of 1979 pickups, Broncos, Jeeps, vans, and utility wagons, L78-15 is one of the key bias-ply truck and SUV sizes of the year. It appears on Chevrolet, Dodge, Ford, GMC, Jeep, and Plymouth applications, often on vehicles with multiple possible tire packages. Current products include blackwall, narrow whitewall, and wide whitewall choices from Coker Classic and BFGoodrich, with listed rim-width ranges from 5.50 to 8.00 inches and load capacities around 1,970 pounds on the examples shown. This makes it a flexible size for owners seeking either utility character or more classic styling.

Rim Diameter: 16 in  ·  Sidewalls: Wide Whitewall, Blackwall

The 650-16 size is a bias-ply fitment used here on the 1979 Chevrolet C/K Pickup and 1979 GMC C/K Pickup. Although those trucks are far newer than the size’s vintage appearance might suggest, the listed tire offerings show why exact wheel and application verification is essential. Available products include blackwall and wide whitewall bias-ply choices from BFGoodrich, Coker Classic, Firestone, and Garfield, with several examples listing 4.50- to 5.00-inch rim-width compatibility. Because 1979 pickups could also use other 15-, 16-, and 16.5-inch tires, this size should be matched carefully to the actual truck configuration.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall

LR78-15 is a radial fitment used on many 1979 trucks, vans, and large utility vehicles, including Chevrolet, Dodge, Ford, GMC, Lincoln, and Plymouth applications. The listed product is a Firestone Steel Belted 721 with a narrow whitewall and bias-profile radial construction, giving this size a particularly period-specific look. Its published rim-width range of 5.50 to 8.00 inches and load capacity of 1,970 pounds @ 32 psi highlight its suitability for larger vehicles. This is a useful size for shoppers who want radial behavior while maintaining a strong late-1970s alphanumeric appearance.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

This bias-ply 16.5-inch size is used on a variety of 1979 heavy-duty trucks, vans, and large wagons, including Chevrolet, Dodge, Ford, GMC, Jeep Truck, and Plymouth applications. The 16.5-inch wheel diameter is a major fitment distinction because it is not interchangeable with 16-inch wheels. Available products are blackwall STA commercial-style tires in Traxion and Transport Highway series, emphasizing utility use rather than decorative sidewall styling. For any 1979 vehicle using 875-16.5, wheel verification is essential, especially on trucks or vans that may have been converted over the years to other wheel and tire setups.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

950-16.5 serves heavier 1979 truck and van applications, including the 1979 Chevrolet C/K Pickup, 1979 Chevrolet Suburban, 1979 Dodge Pickup, 1979 Ford E-350 Club Wagon, 1979 Ford F-250, 1979 Ford F-350, 1979 GMC C/K Pickup, 1979 GMC Suburban, and 1979 Jeep Truck J-20. The listed blackwall STA Traxion and STA Super Transport products include 16.5-inch diameter, 6.50- to 6.75-inch rim-width guidance, and a 2,780-pound maximum load capacity on both examples. This is a clearly heavy-duty fitment, so load needs, wheel condition, and actual truck configuration should all be reviewed before ordering.

Rim Diameter: 16 in  ·  Sidewalls: Blackwall, Wide Whitewall

The 750-16 size appears on 1979 heavy-duty Chevrolet, Ford, and GMC truck and Suburban applications. As a bias-ply 16-inch fitment, it occupies a different place in the 1979 landscape than the more common passenger-car radials and alphanumeric 15-inch tires. Available products include blackwall and wide whitewall choices from Firestone, Lester, and BFGoodrich, with several examples listing 5.00- to 6.00-inch rim-width compatibility and load capacities up to 1,850 pounds in the products shown. Owners should verify whether the vehicle is restored for show, preserved as a utility truck, or modified for modern road use.

8.75R16.5 is a radial heavy-duty size used across a broad group of 1979 pickups, vans, large wagons, and club wagons from Chevrolet, Dodge, Ford, GMC, and Plymouth. The key distinction here is the 16.5-inch wheel diameter paired with radial construction, making it important not to confuse with similarly written 16-inch or bias-ply sizes. No product specifics are listed in this section, but the fitment pattern suggests applications where load-carrying ability and commercial-style duty matter more than decorative sidewall treatment. Always confirm the actual wheel diameter on the vehicle before selecting a replacement.

This bias-ply size is listed only for the 1979 Chevrolet C/K Pickup and 1979 GMC C/K Pickup. Its numeric format and 16-inch wheel diameter set it apart from radial 16.5-inch truck options that can appear nearby in the same model lines. No product details are shown here, so the most useful guidance is to verify the wheel itself and the truck’s intended use before shopping by size. On 1979 pickups, different gross-weight configurations and wheel packages could lead to very different tire needs even within the same make and model family.

10-15 is a bias-ply truck and utility size associated with the 1979 Chevrolet C/K Pickup, 1979 Dodge Ramcharger, 1979 GMC C/K Pickup, and 1979 Jeep Truck J-10. This is a specialty fitment compared with mainstream passenger-car radials, and it belongs to vehicles where wheel type, load expectations, and suspension clearance matter. No product lineup is listed here for this size, so careful confirmation of the exact wheel and vehicle setup is especially important. It should be treated as a dedicated utility fitment rather than a general substitute for other 15-inch truck sizes.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

The 10-16.5 size is listed for the 1979 Chevrolet C/K Pickup and 1979 GMC C/K Pickup and represents a heavy-duty bias-ply truck fitment. A listed STA Traxion product shows this size in a blackwall commercial-style pattern with a 16.5-inch rim diameter, 8.25-inch rim width, and a maximum load capacity of 2,680 pounds @ 60 psi. That specification alone shows why this size belongs in a work-capable tire category rather than a light-duty passenger setting. Because 16.5-inch applications are very specific, wheel diameter and width should always be confirmed before purchase.

FR78-14 is a radial alphanumeric size used on a wide mix of 1979 domestic passenger cars, including the 1979 Chevrolet Camaro, 1979 Dodge Aspen, 1979 Ford Custom 500, 1979 Ford Granada, 1979 Lincoln Continental, 1979 Mercury Marquis, 1979 Oldsmobile Omega, and 1979 Pontiac Phoenix. This was a common format for mid-size and full-size cars during the period. Product details are not listed here, so selection starts with confirming the exact application within the vehicle line. That matters because neighboring trims or option groups often shifted to ER78-14, DR78-14, or other related sizes.

Rim Diameter: 13 in  ·  Sidewalls: Narrow Whitewall, Wide Whitewall

This radial size fits small 1979 compact cars such as the 1979 Chevrolet Chevette, 1979 Dodge Omni, 1979 Plymouth Horizon, and 1979 Volkswagen Rabbit. The 155/80R13 format is a practical late-1970s small-car radial, balancing economy-oriented dimensions with a more modern construction than older 13-inch bias-ply sizes. Available products focus on whitewall presentation, with narrow and wide whitewall choices from Travelstar, BFGoodrich, Maxxis, and Tornel. Published load capacities around 959 pounds on several listed examples help match the tire to lightweight compact applications while preserving the right period scale.

Rim Diameter: 14 in  ·  Sidewalls: Redline, RWL, Pin-White-Stripe, Blackwall

G70-14 is a bias-ply performance-oriented size used on the 1979 Chevrolet El Camino and 1979 GMC Sprint. This lower-profile alphanumeric format carries a distinctly sporty late-1970s look, and the available products reinforce that character. Firestone and Goodyear offerings include redline, RWL, and pin-white-stripe sidewall treatments, with published rim-width guidance typically in the 6.0- to 8.0-inch range depending on the product. For El Camino and Sprint owners, this size offers an especially strong connection to period styling cues while staying within a true bias-ply product category.

The GR70-14 size appears on the 1979 Chevrolet El Camino and 1979 GMC Sprint as a radial counterpart to the G70-14 bias-ply fitment. That makes it particularly relevant for owners choosing between two different construction styles on the same basic vehicle family. No detailed tire description is listed for every possible product, but the available fitment suggests a late-1970s lower-profile radial approach for sporty car-based utility models. When selecting this size, it is worth confirming whether the vehicle is being kept in a more original-style bias-ply presentation or in a radial-equipped configuration.

Rim Diameter: 14 in  ·  Sidewalls: Wide Whitewall

H78-14 is a bias-ply size used on the 1979 Chevrolet El Camino and 1979 GMC Sprint. Compared with the lower-profile G70-14 and GR70-14 options also found on these models, H78-14 delivers a taller sidewall and a different visual stance. The listed product is a Coker Classic wide whitewall bias-ply with a published 5.50- to 8.00-inch rim-width range and a maximum load capacity of 1,770 pounds @ 32 psi. This size is a reminder that even within one model line, 1979 fitment can vary substantially based on trim, package, and wheel setup.

Rim Diameter: 14 in  ·  Sidewalls: Pin-White-Stripe, Redline, RWL

This bias-ply size is associated with the 1979 Chevrolet Luv Pickup and is presented here with a strong period-performance product selection. Firestone and Goodyear offerings include pin-white-stripe, redline, and RWL sidewall styles, with several listed on 14-inch fitments and 6.0- to 7.0-inch rim-width guidance. Even though the application is a pickup, the tire offerings give this size a sporty late-1970s look rather than a plain utility appearance. That makes careful product choice important for owners balancing period style, intended use, and whether the truck is restored or modified.

A78-13 is a small bias-ply fitment used on 1979 compact domestic cars including the 1979 Chevrolet Monza, 1979 Ford Pinto, 1979 Mercury Bobcat, 1979 Oldsmobile Starfire, and 1979 Pontiac Sunbird. It represents an older sizing and construction style than the radial alternatives also seen across this class. Product details are not listed here, so owners should focus on preserving the correct size category for the exact car and wheel setup. This is particularly relevant on late-1970s compacts, where bias-ply and radial versions could change both the look and the driving character of the vehicle.

This radial heavy-duty size is listed for the 1979 Chevrolet Suburban and 1979 GMC Suburban. The 16.5-inch wheel diameter again stands out as the critical fitment feature, especially on large utility vehicles that may have seen wheel changes over time. Product details are not listed here, but the radial construction suggests a more road-oriented heavy-duty option than neighboring bias-ply truck sizes. Because Suburbans from this era could carry a wide range of tire packages, confirming the actual wheel diameter and the vehicle’s working or restored role is essential before choosing a replacement.

Rim Diameter: 16 in  ·  Sidewalls: Wide Whitewall, Blackwall

700-16 is a bias-ply size used on the 1979 Chevrolet Suburban and 1979 GMC Suburban. Available products include blackwall and wide whitewall offerings from Lester, Avon, BFGoodrich, and Firestone, showing that this size can support either utility-minded or more traditional classic styling goals. Several listed tires include published rim-width compatibility in the 4.50- to 5.50-inch range and load capacities approaching or exceeding 1,800 pounds on some examples. For these large utility vehicles, the right choice depends on whether the priority is period appearance, service-type use, or a combination of both.

Rim Diameter: 15 in  ·  Sidewalls: Dual-White-Stripe, Narrow Whitewall

J78-15 is a bias-ply size used on larger 1979 van and wagon applications, including Chevrolet Van, Dodge van-based models, GMC van models, and the 1979 Plymouth Wagon. The listed products are BFGoodrich Silvertown Classic Bias Ply tires offered in dual-white-stripe and narrow whitewall styles, with published 5.50- to 7.00-inch rim-width compatibility and a maximum load capacity of 1,860 pounds @ 32 psi. This makes J78-15 a good example of a fitment where sidewall styling can play a large role, especially for owners restoring family haulers and full-size vans from the era.

JR78-15 is a radial alphanumeric size used on 1979 Chevrolet and GMC van applications, including the 1979 Chevrolet Van Sportvan, 1979 Chevrolet Van Van, 1979 GMC Rally, and 1979 GMC Vandura. This size gives those large van platforms a radial alternative within period lettered sizing. No detailed product specifications are listed here, but the fitment itself is useful for owners comparing radial and bias-ply options in otherwise similar van applications. Because these vans were often heavily optioned or converted, wheel size and the vehicle’s present-day configuration should be verified before selection.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

The 800-16.5 size is a bias-ply heavy-duty fitment used on many 1979 trucks, vans, and club wagons from Chevrolet, Dodge, Ford, GMC, and Plymouth. Listed products include blackwall STA Super Transport and STA Traxion tires, with published 16.5-inch diameter, 6.00- to 6.50-inch rim-width guidance on one option, and commercial-style construction intended for utility use. Because 16.5-inch applications are highly specific, this size is best approached by confirming the wheel diameter directly on the vehicle. That is especially important on older trucks and vans that may have been upgraded or repurposed over time.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall

This radial size is associated here with the 1979 Chrysler Newport and represents a full-size passenger-car fitment with a relatively tall sidewall and traditional late-1970s proportions. Available products emphasize classic styling, including wide and narrow whitewall choices from Coker Classic Star Series and American Classic. Several listed tires include 15-inch fitment, 5.00- to 7.00-inch rim-width guidance, and load capacities in the mid-1400-pound range. For a large Chrysler application, this size offers a straightforward path for owners who want a radial tire while still preserving a period-appropriate sidewall appearance.

DR78-14 is a radial alphanumeric size used on 1979 domestic compact and mid-size cars including the 1979 Dodge Aspen, 1979 Ford Fairmont, 1979 Ford Granada, 1979 Mercury Monarch, 1979 Mercury Zephyr, and 1979 Plymouth Volare. It sits in the common late-1970s zone where several related trims could use different lettered radial sizes within the same model family. No product details are shown here, so the practical advice is to verify the exact size on the specific car before moving to product selection. This helps avoid confusion with nearby ER78-14 or FR78-14 applications.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

165R13 is a shared 1979 radial fitment found on many compact cars, including the 1979 Fiat 124, 1979 Fiat 131, 1979 Honda Accord, 1979 Mazda RX-7, 1979 Nissan 510, 1979 Plymouth Arrow, 1979 Renault, and 1979 Toyota Corolla. This metric radial size was a common step up from narrower economy fitments while still preserving small-car proportions. Available products are blackwall options from Michelin and Dunlop, including Michelin XAS and XAS-FF series tires with published rim-width guidance on some listings. This size is well suited to owners seeking a period European-style radial presentation.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall

The 600-13 size is a bias-ply fitment listed for the 1979 Dodge Colt, 1979 Plymouth Arrow, and 1979 Renault. This small numeric format highlights how some compact cars in 1979 still used older-style bias-ply sizing even as radial metric alternatives were becoming widespread. Available BFGoodrich Silvertown Classic Bias Ply choices include both wide and narrow whitewall treatments, with published rim-width compatibility of 4.00 to 4.50 inches and a maximum load capacity of 1,010 pounds @ 32 psi. Owners should confirm whether their car retains its bias-ply specification rather than assuming a radial replacement path.

This bias-ply size appears on a wide range of 1979 small imports and compact economy cars, including the 1979 Dodge Colt, 1979 Honda Civic, 1979 Mazda GLC, 1979 Nissan 210, 1979 Plymouth Champ, 1979 Subaru DL, 1979 Subaru GL, and 1979 Toyota Corolla. It reflects the fact that late-1970s entry-level cars could still be fitted with traditional numeric bias-ply tires. No product details are listed here, so the key point is identification. On many of these cars, a neighboring trim or market version may also appear with a metric radial size, so exact application matters.

6.00-14 is a bias-ply size used on a select group of 1979 compact pickups and small utility vehicles, including the 1979 Dodge D50, 1979 Ford Courier, 1979 Mazda B2000, and 1979 Plymouth Arrow. This numeric format is different from later metric light-truck sizing and should be treated as its own fitment category. Product details are not listed here, but the application spread suggests practical small-truck use rather than decorative passenger-car styling. Because these vehicles often lead hard working lives and may have been modified, wheel width and actual tire clearance deserve a quick check before ordering replacements.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall, Narrow Whitewall

The 185R14 size is a widely shared radial fitment across 1979 cars and vans including the 1979 Dodge D50, 1979 Mercedes-Benz 280, 1979 Mercedes-Benz 300, 1979 Nissan 720 Pickup, 1979 Peugeot 504, 1979 Volkswagen Campmobile, 1979 Volkswagen Kombi, 1979 Volkswagen Van Delivery Van, 1979 Volvo 265, and 1979 Volvo DL. Available products include blackwall and narrow whitewall choices from Michelin, Phoenix, and Vredestein. Published rim-width ranges generally fall in the 4.0- to 6.5-inch area on listed examples, making this an especially versatile size spanning passenger and light utility applications.

165/75R13 is a compact radial fitment used on the 1979 Dodge Omni, 1979 Fiat Strada, and 1979 Plymouth Horizon. It reflects the late-1970s move toward slightly lower-profile metric sizing on front-drive and compact imported platforms. No product details are listed here, but the size itself is useful because it distinguishes these applications from narrower 155/80R13 and broader 175-series alternatives. On small hatchbacks and compact sedans, a change in aspect ratio can noticeably alter appearance, so owners should verify the exact listed size before substituting another 13-inch radial.

This radial 16.5-inch size is used on 1979 Dodge, Ford, and van-based heavy-duty applications, including the 1979 Dodge Pickup, 1979 Dodge Van Compact Van, 1979 Dodge Van Tradesman Van, 1979 Ford E-250 Club Wagon, and 1979 Ford Van E-250 Econoline Van. The important feature is the 16.5-inch wheel requirement, which should always be confirmed directly. Product details are not listed here, but the radial construction signals a different road feel from comparable bias-ply commercial sizes. It is best suited to owners who have verified that the vehicle still retains its correct heavy-duty wheel and tire setup.

ER78-15 is a radial alphanumeric size used on larger 1979 van and wagon applications, specifically the 1979 Dodge Sportsman Wagon, 1979 Dodge Van Compact Van, 1979 Dodge Van Tradesman Van, and 1979 Plymouth Wagon. This fitment sits in the broad family of period American lettered radials, but on vehicles whose actual weight and use can vary considerably. No detailed product specifications are listed here, so the most important step is to match the size to the exact van or wagon configuration. Sidewall styling, load needs, and wheel width can all matter on these larger family and utility vehicles.

The 175/75R15 size is listed for the 1979 Dodge St Regis and represents a relatively narrow full-size passenger-car radial on a 15-inch wheel. A blackwall product selection is not listed; however, available products include an Avon CR6ZZ and a Vredestein Sprint Classic in blackwall form, both with published 4.5- to 6.0-inch rim-width compatibility and load capacities on the Vredestein example. This size has a more European-style proportion than many wider domestic full-size fitments, so confirming the exact St Regis application is worthwhile before selecting a replacement.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

145R13 is a narrow radial size used on lightweight 1979 small cars including the 1979 Fiat 128, 1979 Fiat Strada, 1979 MG Midget, and 1979 Renault. It is one of the slimmest metric radial fitments of the year and suits compact wheelhouses and modest vehicle weight. Available products are blackwall options from Michelin and Firestone, with the Firestone F560 listing a published 4.00- to 5.00-inch rim-width range and 825-pound maximum load capacity. This size is especially relevant for owners preserving the nimble, lightweight feel of small imported and British 1979 cars.

The 160R13 size is associated here only with the 1979 Fiat 131. It sits between narrower 155R13 and more common 165R13 sizes, making it a relatively specialized compact radial fitment. Product detail is not listed here, so owners of a 1979 Fiat 131 should begin by confirming whether the car still carries the proper wheel and tire specification for this exact size. On smaller European sedans, seemingly small changes in width and overall profile can affect both appearance and steering feel, so it is best not to assume interchangeability with more common 13-inch sizes.

165/70R13 is a specialized radial fitment used here on the 1979 Fiat X-1/9. Its lower profile compared with taller 80-series metric sizes fits the sporty proportions of a compact two-seat car. No product details are listed in this section, but the format itself points to a more handling-oriented late-1970s fitment. Because the X-1/9 is a tightly packaged sports car, wheel and clearance checks are especially valuable before changing brands or tire models within the same size. Owners should aim for the correct size category first, then evaluate sidewall and performance priorities.

HR78-14 is a radial alphanumeric size used on larger 1979 domestic passenger cars including the 1979 Ford 500/Squire/GT, 1979 Ford Custom 500, 1979 Ford LTD, 1979 Ford LTD II, 1979 Mercury Cougar, and 1979 Mercury Marquis. This was a common fitment style for full-size and personal luxury models at the time. No specific product details are listed here, but the size’s broad domestic use means sidewall appearance and overall stance can be just as important as construction. Owners should confirm the exact model and trim because neighboring applications within the same family may use different lettered sizes.

The 195R14 size is used on 1979 compact pickups including the 1979 Ford Courier, 1979 Mazda B2000, and 1979 Nissan 720 Pickup. This metric radial format gives these light trucks a practical road-oriented fitment that differs from the older numeric bias-ply alternatives also listed on some of the same models. Product details are not shown here, so the main value of this size description is distinguishing it from 6.00-14 or 700-14 applications. On late-1970s mini trucks, correct size selection can influence both stance and clearance, particularly if the vehicle has seen wheel changes.

Rim Diameter: 14 in  ·  Sidewalls: Pin-White-Stripe, Redline, RWL

E70-14 is a bias-ply performance-style size associated with the 1979 Ford Courier. The available product selection leans strongly into period appearance, with Firestone and Goodyear offerings in pin-white-stripe, redline, and RWL sidewall styles. Several listed examples include 6.0- to 7.0-inch rim-width guidance and maximum load capacities around 1,400 pounds. This size stands apart from plain utility-truck fitments and can dramatically affect the vehicle’s visual presentation. Owners should verify that their particular Courier uses this sporty bias-ply application rather than one of the more conventional pickup tire sizes also found for the model.

GR78-14 appears on 1979 full-size Ford and Mercury passenger cars, including the 1979 Ford Custom 500, 1979 Ford LTD, and 1979 Mercury Marquis. As an alphanumeric radial size, it sits squarely in the mainstream of larger domestic-car fitment for the period. Product specifics are not listed here, but this type of size often matters as much for overall visual balance as for pure dimensions. A full-size sedan equipped with GR78-14 can look noticeably different from one using a 70-series alternative, so the exact tire size should be confirmed before choosing among available product families.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

The G78-15 size is used on a small but varied group of 1979 truck and utility vehicles including the 1979 Ford E-100 Club Wagon, 1979 Ford F-100, 1979 Ford Van E-100 Econoline Van, 1979 Jeep CJ5 & CJ7, and 1979 Nissan 720 Pickup. Listed products include wide whitewall Coker Classic bias-ply tires and a blackwall STA Super Traxion utility tire. Published load capacities around 1,620 pounds on the passenger-style options underline its versatility, but buyers should still separate show-oriented sidewall styling from utility-focused tread design when choosing within this size.

F78-15 is a bias-ply fitment used on the 1979 Ford F-100 and 1979 Ford Van E-100 Econoline Van. As a lettered 15-inch truck and van size, it belongs to the older alphanumeric bias-ply family rather than modern metric light-truck sizing. Product details are not listed in this section, so the practical point is to verify the exact use case of the vehicle. An F-100 restored to factory-style proportions may call for a different visual treatment than an Econoline van kept for utility or cruising, even though both share the same basic size designation.

This bias-ply size is associated with the 1979 Ford Fairmont and 1979 Mercury Zephyr. It is one of several different 14-inch fitments used across these compact domestic platforms, which also appear with radial letter sizes such as BR78-14, CR78-14, and DR78-14. No product details are listed here, but that variety makes exact size confirmation especially important. For owners seeking the right 1979 tire fitment, B78-14 should be treated as a specific bias-ply application rather than a generic 14-inch compact-car tire, since construction and profile can differ noticeably from the radial alternatives.

BR78-14 is a radial alphanumeric fitment used on the 1979 Ford Fairmont, 1979 Ford Mustang II, and 1979 Mercury Capri. This size represents a middle ground within late-1970s compact performance and sporty personal-car applications. Product specifics are not listed here, but the size is useful because it separates these cars from similar models wearing bias-ply B78-13 or C78-14 sizes, as well as other radial letter sizes. On these compact Ford-family cars, sidewall profile and handling feel can vary significantly across tire packages, so selecting by exact fitment is more important than choosing by wheel diameter alone.

The CR78-14 size appears on the 1979 Ford Fairmont, 1979 Ford Mustang II, 1979 Mercury Capri, and 1979 Mercury Zephyr. As a radial alphanumeric size, it reflects the common late-1970s pattern of multiple closely related tire options within a single compact-car platform. No product details are listed here, but owners should note that these same models may also show B78-14, BR78-14, C78-14, or DR78-14 depending on trim and package. That makes the exact CR78-14 designation important for preserving correct overall proportions and avoiding a mismatch in stance or road feel.

DR70-14 is listed only for the 1979 Ford Fairmont, making it a relatively focused sporty radial application within the 1979 Ford compact range. The lower 70-series profile distinguishes it from taller 78-series alternatives and gives the car a more contemporary late-1970s look. Product details are not listed here, so the value lies in recognizing that a Fairmont could wear several different tire formats depending on specification. Owners should confirm whether the vehicle is equipped for this lower-profile radial size before shopping, especially if the car’s wheels have been changed over the years.

Rim Diameter: 12 in  ·  Sidewalls: Blackwall

The 145R12 size is used on the 1979 Ford Fiesta and is one of the smallest radial fitments in the 1979 range. It matches the compact proportions of a lightweight front-drive hatchback and should not be confused with the more common 13-inch sizes used on many other small cars from the same year. The listed Michelin MX product is a blackwall radial with a 12-inch rim diameter, 4.5-inch rim width, and 145R12 72S specification. On a Fiesta, preserving the correct 12-inch fitment is especially important for appearance, gearing feel, and clearance.

155R12 appears on the 1979 Ford Fiesta and some 1979 Honda Civic applications, making it a small but important compact-car radial size. It offers a bit more width than 145R12 while keeping the same small-wheel, economy-car proportions that defined many late-1970s imports. Product details are not expanded here beyond the fitment listing, so owners should use this size to distinguish the correct application from neighboring 12- and 13-inch alternatives. On very small cars, even a modest change in section width or wheel diameter can alter steering feel and body clearance.

The 215R15 size is listed specifically for the 1979 Ford LTD II. It is a radial fitment with a relatively tall profile, and unlike lower-profile 70-series sizes, it preserves a fuller sidewall appearance on a larger domestic car. No product details are listed here, so the emphasis is on exact identification. Because the LTD II also appears with HR70-15 and GR78-15, owners should verify which wheel and tire package their particular car uses. That distinction matters for both the overall stance of the vehicle and the type of replacement tire that best matches its character.

C78-13 is a bias-ply size used on the 1979 Ford Mustang II and 1979 Mercury Capri. This compact 13-inch alphanumeric fitment belongs to the older bias-ply side of the late-1970s tire market and contrasts with the radial letter sizes also found on these model lines. No product details are shown here, but buyers should recognize that moving between C78-13 and a radial alternative is not simply a matter of wheel diameter. Construction, profile, and appearance all change, so the correct starting point is always the exact size associated with the vehicle.

Rim Diameter: 390mm in  ·  Sidewalls: Blackwall

190/65R390 is a specialized metric-millimeter radial size used on the 1979 Ford Mustang II and 1979 Peugeot 604. Like other TRX-system sizes, it requires a 390mm wheel rather than a conventional inch-based rim. The listed Michelin TRX-B product includes specific metric rim-width options and a blackwall sidewall style, underscoring how dedicated this fitment is. For either of these 1979 vehicles, it is important to confirm whether the original TRX wheel system remains in place. A car converted to conventional wheels will need a different fitment path than one still using TRX equipment.

A70-13 is a bias-ply size associated here with the 1979 Ford Pinto. Its lower-profile alphanumeric format gives it a sportier character than taller small bias-ply sizes, but it remains part of the traditional bias-ply family rather than a modern radial format. Product details are not listed here, so the practical fitment message is simply to verify whether a specific Pinto uses this size or one of the other 13-inch options also seen in similar compact domestic cars of the era. Exact sidewall profile matters noticeably on small, light vehicles.

This heavy-duty bias-ply size is listed only for the 1979 GMC C/K Pickup. Its 19.5-inch wheel diameter places it in a distinctly commercial and work-oriented category compared with the more common passenger and light-truck sizes found elsewhere in the 1979 range. No product details are shown here, but the fitment itself signals that buyers should be highly attentive to wheel diameter, load expectations, and vehicle configuration. On a truck with this type of tire size, there is little room for assumption; exact wheel and service requirements should lead the selection process.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, Wide Whitewall, Redline

205/75R14 is a radial size used on the 1979 GMC Caballero plus several 1979 Pontiac models, including the Grand LeMans, Grand Prix, and LeMans. It combines a fuller sidewall with a wider section than smaller 14-inch car tires, making it a strong fit for mid-size domestic applications. Available products include wide and narrow whitewall options from American Classic, Coker Classic, Maxxis, and Custom Cruiser, with published rim-width ranges commonly in the 5.00- to 7.50-inch span. This size is especially useful for owners prioritizing classic sidewall styling in a radial construction.

The 6.00-12 size is listed only for the 1979 Honda Civic and represents one of the more uncommon small-car bias-ply fitments of the year. This is a traditional numeric size rather than a metric radial, so it belongs to a very different fitment category than the Civic’s 155R12 or 155R13 applications. Product details are not provided here, making accurate identification especially important. For a small front-drive economy car, wheel diameter and tire profile are closely tied to the car’s original proportions, so confirming the exact size before shopping is a worthwhile first step.

ER70-15 is a radial size shared by the 1979 Jaguar XJ12C, 1979 Jaguar XJ12L, 1979 Jaguar XJ6, and 1979 Jaguar XJS. It reflects the kind of lower-profile grand touring fitment seen on premium European cars in the late 1970s. Available products are Firestone Wide Oval Radial offerings in redline and RWL form, both using a bias-look radial construction. That gives this size a distinctive blend of radial behavior with strong period styling. For classic Jaguar owners, ER70-15 is a good example of a fitment where the visual sidewall treatment can be almost as important as the size itself.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall, Blackwall, Wide Whitewall

The 205/70R15 size appears on premium 1979 European applications including the 1979 Jaguar XJ6, 1979 Jaguar XJS, and 1979 Maserati Merak. This radial fitment offers a useful balance between touring comfort and late-1970s performance proportions. Available products span very different visual directions, from blackwall Michelin XWX and Avon CR6ZZ tires to narrow and wide whitewall options from Maxxis and American Classic. Several listings include published rim-width ranges from roughly 5.0 to 7.5 inches and load capacities near 1,500 pounds, helping owners evaluate both wheel compatibility and desired appearance.

The 9-15 size is listed specifically for the 1979 Jeep CJ7 and belongs to the older bias-ply truck and off-road style of fitment. Unlike the Jeep’s also-listed L78-15 applications, this numeric size points to a distinct tire category with its own profile and visual stance. No product details are listed here, so the priority is accurate identification of the exact wheel and configuration on the vehicle. A CJ7 that has been modified for off-road use or fitted with different wheels over the years may no longer match this original-style size path.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

175/70R14 is a radial fitment used on the 1979 Lancia Beta and 1979 Mercedes-Benz 280. It is a relatively narrow, lower-profile 14-inch size that suits compact executive and sporting European cars of the period. The listed product is a Travelstar narrow whitewall radial, which creates an interesting period-style option for cars that might otherwise be expected to wear blackwalls. Because this size appears on two different makes with different vehicle character, owners should still verify wheel width and overall presentation goals before purchase, especially if the car has been restored with non-original wheels.

The 225R15 size is associated here only with the 1979 Lincoln Continental. This radial format combines a substantial section width with a tall sidewall, making it well suited to a large luxury coupe or sedan. No product details are listed in the available selection, so owners should concentrate first on verifying that their Continental actually uses this size rather than one of the other Lincoln-related 14- or 15-inch fitments from the same period. On a big luxury car, maintaining the proper overall tire profile has a strong effect on both visual balance and road demeanor.

205/60R14 is a distinctly sporty radial size used on 1979 Lotus models including the Eclat, Elite, and Esprit. The shorter sidewall and relatively broad section width give these cars a more focused performance stance than conventional family-car fitments of the same era. Available products include blackwall Michelin Primacy 3 plus wide whitewall and RWL choices from American Classic, Coker Classic, and BFGoodrich. That unusual blend means buyers can lean toward contemporary blackwall performance presentation or a more custom classic look, but wheel width and body clearance should still be reviewed carefully on these low-profile sports cars.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, RWL, Redline, Blackwall

This radial size is used on the 1979 Lotus Esprit and 1979 Saab 900, bringing together two very different performance-oriented applications under one fitment. The 60-series profile creates a more modern late-1970s look than taller touring sizes, and current product options are varied. Available choices include blackwall Michelin Primacy 3, RWL BFGoodrich Radial T/A, a BFGoodrich redline, and a wide whitewall BFGoodrich Silvertown Radial. Published rim-width compatibility typically falls between 5.50 and 7.00 inches on listed products, making wheel confirmation especially worthwhile before choosing a sidewall style.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, RWL

235/60R15 is a wide lower-profile radial size associated here with the 1979 Lotus Esprit. Its dimensions give a pronounced performance stance, and the available products reinforce that character. Choices include a blackwall M&H Racemaster drag radial plus RWL options from Cooper Cobra Radial G/T and BFGoodrich Radial T/A. Several listings show rim-width compatibility from about 6.5 to 8.5 inches and load capacities around 1,642 pounds. This is a size where owners should pay close attention to intended use, since the product mix ranges from street-oriented raised-letter styling to a more specialized drag-race application.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

This radial size is listed for the 1979 Maserati Merak and is represented by a Michelin XWX blackwall product. That pairing places it firmly in the category of premium European late-1970s performance touring fitment. Although only one product is shown, the size itself is meaningful because it provides a taller sidewall than many later sports-car tires while still maintaining a purposeful stance. For a Merak, preserving the intended wheel and tire relationship is important for both appearance and driving feel, so owners should confirm wheel dimensions and overall configuration before making a final selection.

Rim Diameter: 14 in  ·  Sidewalls: Redline, RWL

ER70-14 is a radial fitment used on the 1979 Mazda B2000 and represented here by Firestone Wide Oval Radial products in redline and RWL styles. Its bias-look radial construction gives this size a strong period appearance while still staying within a radial format. That makes it a notable option for a late-1970s mini truck where owners may want more visual character than a plain blackwall tire provides. Because the B2000 also appears with other pickup-related sizes, the exact wheel and application should be confirmed before choosing between an appearance-focused radial and a more conventional truck tire path.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, Wide Whitewall

The 185/70R15 size is shared by the 1979 Mazda RX-7 and 1979 Porsche 911, making it one of the more interesting small-to-medium 15-inch performance radial fitments of the year. Available products include blackwall Michelin XWX, Dunlop Sport Classic, and Avon CR6ZZ tires, plus a wide whitewall BFGoodrich Silvertown Radial. Published rim-width guidance generally falls in the 4.5- to 6.5-inch range on listed examples. This size works well for owners seeking a period sports-car radial, though final selection should reflect whether the car is being restored with a factory-style blackwall look or a more customized presentation.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

175R14 is a radial size used on the 1979 Mercedes-Benz 240, 1979 Peugeot 504, 1979 Toyota Celica, 1979 Toyota Corona, and 1979 Volvo DL. This tall-profile metric radial was a familiar fitment on many practical European and import cars of the era. Current product options are blackwall only, with choices from Michelin and Vredestein including published rim-width guidance around 4.5 to 6.0 inches on several listings. That keeps the focus on classic road-car proportions and straightforward radial construction rather than decorative sidewall treatments, making it a strong fit for clean, period-minded restorations.

Rim Diameter: 14 in  ·  Sidewalls: RWL, Blackwall, Pin-White-Stripe, Narrow Whitewall, Redline, Wide Whitewall

This radial size appears only on the 1979 Mercedes-Benz 6.9, one of the most specialized luxury-performance applications in the 1979 range. The available product mix is unusually broad, including Michelin XWX blackwall, Cooper Cobra Radial G/T RWL, BFGoodrich Silvertown Radial with pin-white-stripe, and Maxxis narrow whitewall choices. Published rim-width ranges generally run from 5.5 to 7.5 inches depending on the product, with load capacities around the mid-1500-pound level on some listings. For a 1979 Mercedes-Benz 6.9, the tire choice can significantly influence both appearance and how period-correct the overall presentation feels.

The 6.45-13 size is listed only for the 1979 Nissan 510 and represents a traditional bias-ply small-car fitment. It belongs to the older numeric sizing family and should be kept distinct from the metric radial alternatives used on many other compact imports from the same year. No product details are listed here, so the main priority is exact size confirmation. For a lightweight compact sedan, a move away from the correct numeric size can alter proportions quickly, making this fitment particularly relevant for owners focused on a period-appropriate stance.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, Blackwall

700-14 is a bias-ply size used on the 1979 Nissan 720 Pickup and 1979 Toyota Pickup. The available BFGoodrich Silvertown Classic Bias Ply products are offered in blackwall and narrow whitewall styles, with published 5.00- to 5.50-inch rim-width compatibility and a maximum load capacity of 1,360 pounds @ 32 psi. That gives owners of these compact pickups a straightforward choice between a plain utility look and a more styled classic presentation. Because these trucks could also appear with other 14-inch or radial options, it is smart to verify the exact tire size before ordering.

This radial size is associated only with the 1979 Plymouth Horizon. It sits within the compact front-drive tire family but offers a taller profile than 165/75R13 or 155/80R13 alternatives. No product details are listed here, so the best use of this fitment information is to distinguish it from the Horizon’s other possible 13-inch radial sizes. On small hatchbacks, that difference can affect both visual proportion and gearing feel. Owners should confirm the exact tire size shown for the specific car rather than assuming that any 13-inch compact radial will provide the same result.

Rim Diameter: 16 in  ·  Sidewalls: Blackwall, Wide Whitewall

205/55R16 is a modern-feeling radial performance size used on the 1979 Porsche 911 and 1979 Porsche 930. It stands out in the 1979 fitment landscape because of its low profile and 16-inch wheel diameter, both pointing to a clearly sporting application. Available products are blackwall performance radials from BFGoodrich and Michelin, with listed rim-width compatibility of 5.5 to 7.5 inches and load capacities up to 1,477 pounds on some examples. For Porsche owners, this is a fitment where exact wheel size and offset are especially important because these cars are sensitive to tire width and clearance.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, RWL, Redline, Blackwall

Used on the 1979 Porsche 911 and 1979 Porsche 928, 215/60R15 is a substantial radial performance fitment with more sidewall than later ultra-low-profile sports-car tires but a distinctly sporting late-1970s shape. Available products include blackwall Dunlop Sport Classic, RWL BFGoodrich Radial T/A, and American Classic Radial versions in redline and wide whitewall form. Published rim-width compatibility generally spans about 5.50 to 7.50 inches, with listed load capacities around 1,411 to 1,477 pounds. This size gives owners flexibility in balancing period style, brand preference, and wheel compatibility.

Rim Diameter: 16 in  ·  Sidewalls: Blackwall

225/50R16 is a low-profile radial fitment used on the 1979 Porsche 911 and 1979 Porsche 930. It is one of the most overtly performance-focused sizes in the 1979 range, combining a wide tread section with a short sidewall and 16-inch wheel diameter. Available products are blackwall choices from BFGoodrich and Michelin, including g-Force and Pilot Sport series tires with published rim-width compatibility from 6.0 to 8.0 inches. Because these Porsche applications are highly sensitive to wheel width and chassis clearance, confirming the exact wheel setup is essential before selecting among the listed products.

The 205/60R15 size is associated here with the 1979 Porsche 924 and offers a lower-profile 15-inch radial suited to a sporty late-1970s chassis. Current product choices include a blackwall Michelin Primacy 3, wide whitewall offerings from American Classic and Coker Classic Star Series, and an RWL BFGoodrich Radial T/A. Several listed products include rim-width guidance from 5.50 to 7.50 inches and load capacities ranging into the 1,300-pound level and above. This size gives 1979 Porsche 924 owners a broad visual range, but fitment should still be checked carefully against the car’s existing wheels.

225/50R15 is listed only for the 1979 Porsche 928, marking it as a specialized low-profile performance fitment. Compared with taller 70-series and 60-series sizes used on many other 1979 vehicles, this designation points to a more aggressive sports-car setup. Product details are not listed here, so the most useful guidance is to treat this as a distinct fitment rather than simply a wider 15-inch alternative. On a 928, wheel width, offset, and overall chassis clearance are important, so owners should verify that the car still retains the proper wheel package before choosing a replacement tire.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

This radial size is used on the 1979 Saab 900 and sits in a relatively uncommon niche among 15-inch applications from the year. Available products are blackwall choices from Avon and Vredestein, both aimed at drivers who want a classic European radial presentation rather than domestic-style whitewalls or raised letters. The listed Vredestein includes a maximum load capacity of 1,168 pounds @ 51 psi and a 4.5- to 6.0-inch rim-width range. For a 1979 Saab 900, this size supports the car’s distinctly European fitment character and should be matched carefully to the existing wheel setup.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall, Blackwall

165R15 appears on the 1979 Saab 900, 1979 Saab 99, and 1979 Volkswagen Beetle, linking two very different but strongly characterful vehicle types through one classic metric radial size. Product coverage is broad, with blackwall, narrow whitewall, and wide whitewall choices from Coker Classic, American Classic, Firestone, and BFGoodrich. Several listed tires include 4.50- to 6.00-inch rim-width compatibility and load capacities around 1,168 pounds. This makes 165R15 a flexible size for owners who want either a simple blackwall look or a more decorative sidewall treatment without leaving the proper fitment family.

180/65R390 is a specialized metric-millimeter radial size associated with the 1979 Saab 900. Like other TRX-style fitments, the 390 designation refers to a metric wheel diameter and should not be confused with a conventional 15-inch rim. No product details are expanded here beyond the fitment listing, but the size itself is the main message: it requires the correct wheel system to work properly. For owners of a 1979 Saab 900, verifying whether the car still wears its original metric-diameter wheels is essential before moving on to any tire-selection decision.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, Wide Whitewall, Redline, Blackwall

The 750-14 size is listed for the 1979 Toyota Pickup and is represented by a broad range of bias-ply products from BFGoodrich, US Royal, and Coker Classic. Available sidewall styles include narrow whitewall, wide whitewall, and redline, with published rim-width compatibility generally in the 5.00- to 5.50-inch range and load capacities around 1,500 to 1,580 pounds on listed examples. That gives this compact pickup an unusually style-rich selection within a utility-oriented size. Owners should still confirm the exact application because the 1979 Toyota Pickup also appears with several other tire sizes.

Rim Diameter: 13 in  ·  Sidewalls: Narrow Whitewall, Wide Whitewall

560-13 is a small bias-ply size used on the 1979 Triumph Spitfire and 1979 Volkswagen Dasher. Its compact dimensions and traditional numeric format make it a specialized fitment compared with the many 13-inch metric radials used elsewhere in 1979. Available products come from BFGoodrich and Firestone in narrow and wide whitewall styles, with published rim-width compatibility between roughly 3.50 and 4.50 inches and an 850-pound maximum load capacity on the listed examples. This size is especially relevant for owners preserving a light, period-correct look on smaller sports and economy-oriented vehicles.

The 185R13 size is listed only for the 1979 Triumph TR7 and is represented by a Michelin XAS-FF blackwall radial. This tall-profile 13-inch metric radial differs meaningfully from the TR7’s also-listed 185/70R13 fitment, so it should not be treated as just another equivalent-size option. The available Michelin product emphasizes a classic European radial approach rather than decorative sidewall styling. For a TR7 owner, the most important step is confirming which of the two 13-inch fitments applies to the car, since the overall proportions and road feel can differ noticeably between them.

155/80D13 is a bias-ply fitment listed for the 1979 Volkswagen Rabbit. The use of the 'D' construction mark distinguishes it from the Rabbit’s also-listed 155/80R13 radial application, making this one of the clearest examples in 1979 of the same basic dimensions appearing with different construction types. No product detail is expanded here beyond the fitment listing, so buyers should focus on verifying whether their Rabbit is set up for the bias-ply or radial version. That distinction affects not only product choice but also the vehicle’s ride, response, and period-correct presentation.
