1977 Vehicle Tire Fitment Guide

The HR78-14 size is a radial fitment used on 1977 American Motors Matador, Ford 500 & Squire, Ford GT, Ford LTD, and Mercury Cougar models. It sits in the domestic alpha-numeric radial family and generally serves larger cars than compact 14-inch metric radials. Product specifics are not listed here for this size, but its role is clear: it offers a radial fitment path for full-size and specialty domestic applications where ride, appearance, and wheel compatibility all need to be balanced carefully. Since both H78-14 and HR78-14 appear in the same year, owners should confirm whether their vehicle is being matched to a bias-ply or radial application.

GR70-15 is a key 1977 performance-oriented radial size used on a broad mix of sporty and upscale models, including the Aston Martin AM, Chevrolet Corvette, Chevrolet Monte Carlo, Pontiac Firebird, Pontiac Grand Prix, Oldsmobile Cutlass, and several Buick models. Available products are Goodyear bias-look radials in GM Custom Tread and Steelgard lines, with pin-white-stripe and raised white letter sidewall styles on 15-inch rims, generally fitting 7.0- to 8.0-inch wheel widths. This size is especially relevant for buyers who want radial construction with a period muscle- and personal-luxury-car appearance. Sidewall styling can significantly change the look of the finished car.

Used on the 1977 Audi 100, MG MGB, and Porsche 924, 165R14 is a metric radial size shared across several European applications. It reflects the narrower, taller-profile radial format common on many imported cars of the period. Available blackwall choices include the Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic, with listed rim-width guidance on some products ranging from 4.0 to 6.0 inches and load ratings up to 1,102 lbs where specified. This size is well suited to owners aiming for authentic European road manners and appearance, but the exact brand and series can influence both period character and intended driving use.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

The 155R13 radial size is one of the most widely shared import fitments for 1977, covering compact models from Audi, Fiat, Honda, Mazda, Nissan, Opel, Renault, Subaru, Toyota, Triumph, and Volkswagen. This narrow metric radial format was common on economical small cars, and current product choices stay within that character. Available blackwall options include Michelin XAS-FF and Dunlop SP Sport Aquajet, with some listed rim widths from 4.00 to 5.50 inches and load capacities up to 937 lbs where stated. Because this size appears on many different makes, shoppers should confirm the exact model and wheel size rather than assuming all small 1977 imports used the same tire.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

175/70R13 is a lower-profile radial size used on 1977 compact import models such as the Audi Fox, Mazda GLC, Nissan 200, Nissan 210, Opel Opel, Volkswagen Dasher, and Volkswagen Scirocco. Compared with taller 80-series radial sizes, this format has a noticeably shorter sidewall and a more modern late-1970s small-car character. The available product shown is an Avon CR6ZZ blackwall radial for 13-inch wheels, with a listed rim-width range of 4.5 to 6.0 inches. That makes this size especially useful for owners who want an import-correct stance and responsive feel without moving away from the vehicle’s documented tire-size family.

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

This 1977 radial size appears on a varied group that includes the BMW 320i & 320iA, Lancia Scorpion, Lotus Elite, Mercury Capri, Toyota Corolla, and Triumph TR7. The 185/70R13 format bridges compact sporty imports and select domestic or European specialty models, giving it broader character than many same-year 13-inch sizes. Available products range from blackwall Avon and Dunlop radials to BFGoodrich Silvertown Radial choices with redline or 2-inch whitewall styling, plus listed rim widths generally between 4.5 and 6.5 inches. That variety lets owners emphasize either a sportier blackwall appearance or a more period-custom look while staying within the correct size range.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

195/70R14 is used on the 1977 BMW 530i & 530iA, Mercedes-Benz 300, and Nissan 280, placing it among the year’s larger European-style and imported radial fitments. The size suggests a wider, lower-profile 14-inch application than 175R14 or 185R14, making it relevant to cars with more substantial performance or luxury character. The listed product is a Dunlop Sport Classic blackwall radial with a 91V service description and a maximum load capacity of 1,356 lbs. This size is best approached as a model-specific fitment where overall width, wheel compatibility, and intended driving feel matter more than simple diameter matching.

The HR70-15 radial size is associated with the 1977 Bentley T2 Series, Ford Thunderbird, Mercury Cougar, and Rolls Royce Silver Shadow. It serves large personal-luxury and premium applications where a broad 15-inch tire contributes to the car’s stance and presence. Available products are blackwall Goodyear-style and premium radial offerings, with the listed example here being a Goodyear bias-look radial from the period-correct sidewall family. Because this size appears on both domestic and high-end British cars, buyers should think beyond diameter alone and confirm the exact wheel width, desired appearance, and the role the car plays as a driven collector vehicle or a show-focused restoration.

GR78-14 is a radial size used on the 1977 Buick Century, Buick Regal, and Pontiac Ventura. It belongs to the domestic alpha-numeric radial family and gives these midsize applications a distinctly late-1970s fitment character. Product details are not listed here for this exact size, but the size itself helps separate these models from nearby FR78-14 and ER78-14 fitments that also appear on similar-era cars. For owners researching replacements, the important question is whether the car’s current wheels and suspension still match the documented GR78-14 application, especially if the vehicle has been restored, lowered, or converted from another wheel-and-tire package.

GR78-15 is one of the most common 1977 domestic radial sizes, spanning a broad mix of Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Oldsmobile, Plymouth, and Pontiac models. It is especially common on midsize and full-size American coupes, sedans, and wagons. Product details are not shown here for this exact size, but its popularity within 1977 fitment makes it a key reference point when narrowing choices by vehicle. Since the same size appears on many very different body styles, buyers should still verify exact model and wheel setup. Shared tire size does not automatically mean identical load, clearance, or appearance priorities.

HR78-15 is the most broadly used 1977 radial size in this guide, appearing on full-size sedans, wagons, utility vehicles, and specialty models from Buick, Cadillac, Checker, Chevrolet, Chrysler, Dodge, Ford, GMC, International, Jeep, Mercury, Oldsmobile, Plymouth, and Pontiac. This alpha-numeric radial fitment crosses traditional passenger and light-truck boundaries more than many other sizes of the year. No specific product listings are shown here for HR78-15, so the real value is in application accuracy. Owners should confirm not only year, make, and model, but also whether the vehicle retains its intended wheel width and ride height, since those factors can affect the suitability of a large 15-inch radial.

Used on several 1977 General Motors intermediates and full-size cars, FR78-15 fits models such as the Buick LeSabre, Chevrolet Chevelle, Chevrolet Chevrolet, Oldsmobile Cutlass, Oldsmobile Delta 88, Pontiac Catalina & Bonneville, Pontiac Firebird, Pontiac Grand LeMans, and Pontiac LeMans. This radial alpha-numeric size occupies an important middle ground between smaller car fitments and the larger GR78-15 or HR78-15 applications. Product details are not listed here, so owners should use the size mainly as a fitment filter tied to the exact model. It is especially useful when researching cars that could appear with more than one 15-inch tire size depending on trim or configuration.

B78-13 is a small domestic bias-ply size used on the 1977 Buick Skyhawk, Ford Mustang, Oldsmobile Starfire, and Pontiac Sunbird. It reflects the lighter, compact-car end of the American market during a period when some vehicles could also be found with radial alternatives. No exact product listings are shown here for B78-13, but the application itself is useful for owners seeking a traditional small-car bias-ply setup. Because 13-inch compacts in 1977 often overlap with nearby radial sizes such as BR78-13 or BR70-13, confirming both the tire-size marking and the wheel fitment is especially important before ordering.

The BR78-13 size is a radial application used on 1977 Buick Skyhawk, Chevrolet Vega, Ford Mustang, Ford Pinto, Mercury Bobcat, Pontiac Astre, and Pontiac Sunbird models. It belongs to the domestic alpha-numeric radial family that helped bridge the gap between earlier bias-ply sizing and more modern metric radial conventions. Product details are not listed here for this exact size, but the size is important for preserving the late-1970s compact-car look and fitment. Since some of these same models also appear with A78-13 or BR70-13, owners should verify the actual wheel-and-tire combination on the car rather than relying on model name alone.

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

E78-14 is a common 1977 bias-ply 14-inch size used on cars and light trucks including the Buick Skylark, Chevrolet Camaro, Chevrolet Luv Pickup, Chevrolet Nova, Dodge Aspen, Dodge Van Tradesman Van, Oldsmobile Omega, Plymouth Volare, and Pontiac Ventura. Available products include Coker Classic wide whitewall options and STA blackwall truck-oriented bias-ply designs, with listed rim-width ranges from 4.50 to 7.00 inches depending on the product and load capacities up to 1,710 lbs in certain applications. That mix makes E78-14 unusual because it serves both styling-focused passenger cars and more work-oriented uses. Choosing by sidewall appearance alone is not enough; intended vehicle use matters.

ER78-14 is a radial fitment shared by 1977 Buick Skylark, Dodge Aspen, Ford Granada, Ford Granada Ghia, Mercury Monarch, Oldsmobile Omega, Plymouth Volare, and Pontiac Ventura models. It is a useful example of how similar late-1970s intermediate cars could use radial sizes that parallel nearby bias-ply options such as E78-14. Product details are not listed here for ER78-14, but the size remains valuable for owners trying to identify a proper radial application without moving to an unrelated modern size. Because these cars often occupy the same segment, wheel changes over time are common, so clearance and wheel width should be checked before final selection.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall

LR78-15 is a large radial size used on heavier 1977 passenger cars and some trucks, including the Cadillac Eldorado, Chevrolet C/K Pickup, Chevrolet Suburban, Chrysler New Yorker, Ford F-150, GMC Suburban, Lincoln Continental, and several Mercury and Plymouth full-size models. A listed option is the Firestone Steel Belted 721 with a .75-inch narrow whitewall, bias-look radial construction, 15-inch rim fitment, and a load rating of 1970 lbs at 32 psi. This size combines substantial visual presence with a more road-oriented radial design. Because it crosses luxury-car and truck applications, wheel width and vehicle load expectations deserve careful attention.

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

G78-15 is a widely used 1977 bias-ply size found on a broad range of domestic trucks, vans, utility vehicles, and a few full-size passenger applications. It appears on vehicles such as the Chevrolet Blazer, Chevrolet C/K Pickup, Dodge Ramcharger, Ford Bronco, Ford F-100, GMC Jimmy, Plymouth Fury, and Plymouth Trailduster. Available products include Coker Classic wide whitewalls and an STA Super Traxion blackwall, all on 15-inch fitments, with listed rim widths generally from 5.00 to 7.00 inches and maximum load capacity up to 1620 lbs where specified. This size can support either a cleaner passenger-style look or a more rugged truck-oriented presentation depending on the chosen tire.

Used across 1977 utility and van-based applications such as the Chevrolet Blazer, Dodge Ramcharger, Ford Bronco, GMC Jimmy, Plymouth Trailduster, and several Dodge and GMC vans, E78-15 is a bias-ply size that leans toward light-truck and multipurpose use. Current products include a Coker Classic wide whitewall plus STA Traxion and STA Transport Highway blackwall tires, giving this size a split personality between restoration appearance and more commercial-style utility. Some listed products also carry higher load-oriented specifications than typical passenger-car tires. When shopping E78-15, it is important to match the product to how the vehicle is actually used rather than choosing only by size stamp.

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

H78-15 is one of the major 1977 bias-ply sizes for trucks, utility vehicles, wagons, and some larger passenger applications. It appears on models including the Chevrolet Blazer, Chevrolet C/K Pickup, Dodge Pickup, Ford F-150, GMC Suburban, International Scout II, Jeep CJ5 & CJ7, Jeep Cherokee, and Plymouth Fury. Available choices include Coker Classic wide whitewalls and STA Traxion blackwalls, with listed rim widths of 5.50 to 7.00 inches and load capacities up to 1830 lbs depending on product. That breadth means H78-15 can suit very different goals, from a more traditional dressed-up sidewall to a tougher, truck-oriented blackwall treatment.

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

The 1977 L78-15 size is a large bias-ply application used mainly on trucks and utility vehicles such as the Chevrolet Blazer, Chevrolet C/K Pickup, Dodge Pickup, Ford Bronco, Ford F-150, GMC Jimmy, and Plymouth Trailduster. Product coverage is relatively broad, including blackwall, narrow whitewall, and multiple wide whitewall choices from Coker Classic and BFGoodrich, with listed rim widths from 5.50 to 8.00 inches and load capacity up to 1970 lbs at 32 psi. This is a good size for owners who need substantial carrying capability but still want period-correct styling options. On lifted or heavily modified trucks, clearance and wheel width should be verified carefully.

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

700-15 is a traditional numeric bias-ply size used on many 1977 domestic trucks and utility vehicles, including the Chevrolet Blazer, Chevrolet C/K Pickup, Dodge Ramcharger, Ford Bronco, Ford F-100, GMC Jimmy, and Plymouth Trailduster. It is also found on several van and wagon applications. Available tires include Firestone and BFGoodrich classic bias-ply products in blackwall and wide whitewall styles, plus an STA Traxion blackwall, with listed rim widths generally around 5.00 to 5.50 inches and load capacity up to 1700 lbs. This size works well for owners who want an older, upright truck-tire profile rather than a wider late-1970s alpha-numeric alternative.

F78-15 is a bias-ply 15-inch size used on 1977 vehicles including the Chevrolet Blazer, Chevrolet Van Sportvan, Dodge Monaco, Dodge Sportsman Wagon, Ford Van E-100 Econoline Van, GMC Rally, Jeep CJ5 & CJ7, Jeep CJ6, Plymouth Fury, and Plymouth Wagon. It serves an interesting mix of wagons, vans, utility vehicles, and some passenger cars. Product details are not shown here for this exact size, but the application pattern suggests a versatile 15-inch fitment from the era’s domestic lineup. Because the same size spans different vehicle types, it is wise to confirm load needs, wheel width, and intended appearance before choosing a replacement.

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

This 1977 numeric bias-ply truck size is used on the Chevrolet C/K Pickup, Chevrolet Suburban, GMC C/K Pickup, and GMC Suburban. The 700-16 format points toward heavier-duty 16-inch work applications rather than standard passenger-car use. Available products include blackwall and wide whitewall classic tires from Lester, BFGoodrich, and Firestone, as well as an Avon Traction Mileage blackwall, with some listed rim widths from 4.50 to 5.50 inches and load capacities up to 1900 lbs where specified. That mix gives owners room to choose between a work-truck look and a more restored presentation, but this size should always be matched carefully to the actual wheel dimensions.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

875-16.5 is a 1977 heavy-duty bias-ply size found on pickups, vans, club wagons, and utility models from Chevrolet, Dodge, Ford, GMC, and Jeep Truck. It is common on vehicles like the Chevrolet C/K Pickup, Ford F-250, Ford F-350, GMC Rally, and Jeep Truck J-20. Current offerings are blackwall STA Traxion and STA Transport Highway tires, both built around a 16.5-inch rim diameter and truck-oriented construction. This is a distinctly heavy-service fitment rather than a general passenger size. Because 16.5-inch wheels are not interchangeable with 16-inch wheels, shoppers should verify the wheel stamp and current vehicle configuration before selecting a tire.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

The 950-16.5 size serves heavier 1977 truck and van applications, including the Chevrolet C/K Pickup, Chevrolet Suburban, Dodge Pickup, Ford F-250, Ford F-350, Ford Van E-350 Econoline Van, GMC C/K Pickup, GMC Suburban, and Jeep Truck J-20. Available STA blackwall products include Traxion and Super Transport versions, both listed with 16.5-inch rim diameter, 6.50 to 6.75-inch rim width guidance, and a maximum load capacity of 2780 lbs at 60 psi. This is a serious load-carrying size for work-oriented vehicles. It should be chosen only after confirming wheel diameter, rim width, and the truck’s actual duty expectations.

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

750-16 is a traditional heavy-duty bias-ply truck size used on 1977 Chevrolet, Dodge, Ford, GMC, and Jeep Truck models, including the Chevrolet C/K Pickup, Ford F-250, Ford F-350, and Jeep Truck J-20. Product choices include blackwall and wide whitewall offerings from Firestone, Lester, and BFGoodrich, with listed rim widths from 5.00 to 6.00 inches and load capacities up to 1850 lbs at 48 psi where specified. This size gives restorers flexibility, since some trucks may benefit from a clean commercial blackwall while others may be finished in a more styled period presentation. It remains important to verify whether the truck uses 16-inch rather than 16.5-inch wheels.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

The 800-16.5 size is another 1977 truck and van fitment with broad domestic use, appearing on Chevrolet, Dodge, Ford, GMC, Jeep Truck, and Plymouth models. It fits vehicles such as the Chevrolet Van Sportvan, Dodge Pickup, Ford E-250 Club Wagon, Ford F-250, GMC Vandura, and Jeep Truck J-20. Available STA blackwall products include Super Transport and Traxion lines, with 16.5-inch rim diameter, 6.00 to 6.50-inch rim-width guidance where listed, and load capacity up to 2045 lbs at 60 psi. This size is best suited to heavier utility work and should be matched closely to wheel specifications and expected load rather than treated as a generic 16-inch truck tire.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

10-16.5 is a specialized bias-ply truck size used on the 1977 Chevrolet C/K Pickup and GMC C/K Pickup. It represents a larger-section 16.5-inch fitment than the narrower 800-16.5 or 875-16.5 sizes, and it is clearly aimed at heavier truck service. The listed product is an STA Traxion blackwall with a maximum load capacity of 2680 lbs at 60 psi, built for an 8.25-inch rim. For owners sorting out truck fitment, this size underlines why exact wheel measurements matter. A 16.5-inch tire cannot be substituted onto a 16-inch wheel, and section width also affects clearance on older trucks.

This 1977 size appears specifically on the Chevrolet Chevette and uses a metric bias-ply format rather than the more common radial version also seen in the same general sizing family. The “D” indicates bias construction, making it a distinct fitment path from radial alternatives used on some other small cars. Product details are not listed here for 155/80D13, so the size is mainly useful as a reminder to verify the actual construction and sidewall marking on the vehicle. On lightweight subcompacts, the difference between metric bias and radial sizing can affect ride character, stance, and overall period presentation.

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

155/80R13 is a small metric radial size used on the 1977 Chevrolet Chevette and Volkswagen Rabbit. It represents a more modern compact-car fitment than the older alpha-numeric or pure numeric domestic sizes elsewhere in the year. Available products include blackwall-free whitewall-focused options from Travelstar, BFGoodrich, Maxxis, and Tornel, with narrow and wide whitewall choices and listed rim widths generally from 4.00 to 5.50 inches. This gives owners some flexibility to choose a cleaner import-style radial or a slightly more dressed-up look. Since both the Chevette and Rabbit also appear in nearby 13-inch size families, the exact sidewall marking should be confirmed first.

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

F70-14 is a performance-flavored 1977 bias-ply size used on the Chevrolet Luv Pickup. While the vehicle application is limited here, the available product range is broader than expected, including Firestone Wide Oval and Goodyear Custom Wide Tread tires in pin-white-stripe, redline, and raised white letter styles. Listed rim-width guidance generally falls between 6.00 and 7.00 inches, with load capacity around 1500 lbs at 32 psi where specified. For owners interested in a more period-sporting look, this size offers several visual directions. Even so, it remains important to match the tire to the truck’s wheel width and real-world use.

A78-13 is a small domestic bias-ply size used on 1977 compact sporty models including the Chevrolet Monza, Chevrolet Vega, Oldsmobile Starfire, Pontiac Astre, and Pontiac Sunbird. It sits at the smaller end of the alpha-numeric bias-ply spectrum and reflects the economy and compact-car fitment trends of the period. Product details are not listed here for this exact size, but it is an important reference for owners who want to retain a bias-ply look rather than moving into a radial-marked alternative. Since several of these same models were also associated with BR70-13 or BR78-13, confirming the intended construction is especially important.

BR70-13 is a radial size used on several 1977 sporty compact models, including the Chevrolet Monza, Chevrolet Vega, Ford Mustang, Ford Pinto, Mazda RX-4, Mercury Bobcat, Pontiac Astre, and Pontiac Sunbird. The low-profile “70” aspect ratio gives it a distinctly more performance-oriented late-1970s appearance than taller 80-series sizes. Product details are not shown here for BR70-13 specifically, but the size itself is useful for identifying compact applications with a sportier stance. Because some of these vehicles also use A78-13 or BR78-13 in other combinations, careful confirmation of wheel size and the desired period look should come before tire selection.

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

650-16 is a traditional bias-ply size used on the 1977 Chevrolet Suburban and Ford F-100. It occupies a narrower and slightly lighter-duty position than larger 16-inch truck sizes used elsewhere in the year. Available products are extensive and include blackwall and wide whitewall tires from BFGoodrich, Coker Classic, Firestone, and Garfield, with listed rim widths from 4.50 to 5.00 inches and maximum load capacities up to 1580 lbs at 32 psi. That makes this size attractive for restorations where appearance matters as much as utility. It is still important to verify whether the truck remains on 16-inch wheels rather than a later replacement size.

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

J78-15 is a bias-ply 15-inch size used on 1977 Chevrolet Van Sportvan, Chevrolet Van Van, GMC Rally, and GMC Vandura models. It appears primarily in full-size van applications where higher capacity and substantial sidewall height are useful. The available BFGoodrich products offer either dual white stripe or narrow whitewall styling, both on 15-inch rims with listed rim widths from 5.50 to 7.00 inches and a maximum load capacity of 1860 lbs at 32 psi. This size is a good fit for owners who want a distinctly period van look. Because these vehicles were often customized, current wheel and suspension changes should be checked before purchase.

JR78-15 is a radial size shared across a broad set of 1977 larger domestic cars and vans, including the Chrysler New Yorker, Chrysler Newport, Ford Custom 500, Ford LTD, Lincoln Continental, Mercury Grand Marquis, Oldsmobile Toronado, Pontiac Safari, and several full-size Chevrolet and GMC vans. This alpha-numeric radial fitment is associated with larger, heavier vehicles than many passenger-car sizes in the year. Product specifics are not listed here for JR78-15, but the size is especially useful when distinguishing upscale and wagon applications from nearby HR78-15 or LR78-15 combinations. Exact wheel dimensions and vehicle weight class should remain part of the selection process.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

165R13 is a versatile 1977 radial size used on compact imports such as the Dodge Colt, Fiat 124, Fiat 131, Lancia Scorpion, Nissan PL610, Nissan PL710, Plymouth Arrow, Renault Renault, and Toyota Corolla. It is a taller-profile metric radial than lower 70-series sizes and suits a broad range of small cars from economy to light sporting use. Current blackwall offerings include Michelin XAS-FF, Michelin XAS, and Dunlop SP Sport Aquajet, with listed rim widths on some products from 4.50 to 6.00 inches and load capacities up to 1,047 lbs. This size is well suited to owners seeking classic European-style radial manners without altering the vehicle’s basic fitment character.

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

600-13 is a small bias-ply size used on the 1977 Dodge Colt, Plymouth Arrow, and Renault Renault. It represents an older-style numeric fitment for compact imported cars at a time when many similar vehicles were also offered with metric radial alternatives. Available BFGoodrich bias-ply products come in 2.00-inch and 1.00-inch whitewall versions, fit 13-inch wheels, and list rim widths from 4.00 to 4.50 inches with a maximum load capacity of 1010 lbs at 32 psi. This makes 600-13 particularly interesting for period-style restorations. Owners should confirm whether the car is meant to remain on bias-ply tires or has already been converted to a radial size family.

This radial 16.5-inch truck size appears on the 1977 Dodge Pickup and Ford Van E-350 Econoline Van. It is one of the few larger truck applications in the year listed specifically as radial rather than bias-ply. Product details are not shown here for 9.50R16.5, but the size itself signals a substantial heavy-duty fitment intended for larger working vehicles. Because 16.5-inch wheels are highly specific, this is not a size to estimate by appearance alone. Before selecting a tire, owners should verify the wheel diameter, check for dual-versus-single use where relevant, and make sure the vehicle still retains the documented wheel setup.

8.75R16.5 is a radial heavy-duty size used on the 1977 Dodge Pickup, Ford E-250 Club Wagon, and Ford Van E-250 Econoline Van. It occupies a larger commercial-style fitment category than ordinary passenger or utility tire sizes. Product listings are not shown here for this exact size, but its presence is important because it distinguishes certain heavier van and truck configurations from nearby bias-ply 16.5-inch options. In practical terms, shoppers should confirm the wheel’s 16.5-inch diameter, the vehicle’s load-carrying role, and whether any later wheel conversion has changed the tire requirements. These applications should be researched with more care than a typical 14- or 15-inch passenger size.

The 8.00R16.5 size is a radial fitment listed specifically for the 1977 Dodge Pickup. It falls within the larger commercial-style tire family used on heavier truck applications and should be treated as a model- and configuration-specific size rather than a general Dodge truck default. Product details are not listed here, so the main selection guidance is to verify the wheel diameter and width along with the intended use of the truck. Older pickups often receive later wheel swaps, and 16.5-inch fitments can be confused with 16-inch wheels. That makes a direct sidewall and wheel inspection especially important before ordering.

700-14 is a bias-ply numeric size used on the 1977 Dodge Van Tradesman Van and Toyota Pickup. Its use across both a domestic van and a small pickup shows how some straightforward 14-inch numeric sizes crossed vehicle categories in the period. Available BFGoodrich classic bias-ply products include blackwall and 1.00-inch narrow whitewall versions, with listed rim widths from 5.00 to 5.50 inches and a maximum load capacity of 1360 lbs at 32 psi. This size can suit either a utility-oriented or mildly dressed-up look. As always with trucks and vans, current wheel fitment and load expectations should be checked before making a final choice.

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

Used on the 1977 Ferrari 308, Lotus Esprit, and Mercedes-Benz 450, 205/70R14 is one of the year’s more upscale and sporting metric radial sizes. It combines a relatively wide section width with a moderate profile, making it suitable for grand touring and performance-oriented applications. Available products cover several visual and functional approaches, including blackwall, narrow whitewall, raised white letter, redline, and dual-redline styles from Maxxis and BFGoodrich, with listed rim widths generally from 5.00 to 7.50 inches and load capacity up to 1433 lbs at 35 psi. This is a size where both appearance and handling character can play a meaningful role in product choice.

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

215/70R15 is used on the 1977 Ferrari 365, Maserati Bora, and Maserati Khamsin, placing it firmly in the realm of larger-displacement grand touring and exotic applications. Current product coverage is broad, with blackwall, wide whitewall, and raised white letter options from Cooper, BFGoodrich, Dunlop, and Avon, plus listed rim-width ranges generally from 5.5 to 7.5 inches and load capacity up to 1620 lbs at 35 psi on some products. This combination makes the size unusually flexible in appearance despite its specialty applications. For buyers, the main decision is whether the goal is a more understated European blackwall look or a more stylized period radial presentation.

The 145R13 size appears on small 1977 imports such as the Fiat 128, Fiat X-1/9, MG Midget, and Renault Renault. This narrow metric radial format is closely tied to lightweight cars where steering feel, compact proportions, and proper overall diameter matter. Current blackwall options include Michelin XAS-FF and Firestone F560 Radial, with listed load capacity up to 825 lbs at 44 psi and rim-width guidance from 4.00 to 5.00 inches where specified. Because these are relatively light and specialized applications, owners should pay close attention to wheel width and the car’s actual stance. Small deviations in tire size can noticeably change appearance on these cars.

160R13 is a radial size listed for the 1977 Fiat 131. It is a fairly specific compact imported-car fitment that sits between narrower 155R13 and broader 165R13 applications. Product details are not listed here for this exact size, so the main fitment value is in identifying the correct size family for the vehicle rather than substituting by approximation. On a compact sedan like the Fiat 131, overall tire width and height can noticeably affect both appearance and clearance, especially at the front. Owners should confirm the sidewall marking on the current tires and check wheel dimensions before deciding on a replacement path.

Rim Diameter: 14 in  ·  Sidewalls: Dual-White-Stripe, Wide Whitewall, Narrow Whitewall

This bias-ply 14-inch size is used on the 1977 Ford 500 & Squire. Available products include BFGoodrich and Coker Classic tires in dual whitewall, narrow whitewall, and wide whitewall styles, with listed rim widths from 5.00 to 7.00 inches and a maximum load capacity of 1620 lbs at 32 psi. Because the fitment is tied to a full-size Ford wagon application, sidewall style can make a big difference in overall presentation. G78-14 is a good example of a size where buyers may prioritize a broad whitewall for a more formal look or choose a subtler stripe while keeping a true bias-ply construction.

6.00-14 is a traditional numeric bias-ply size used on the 1977 Ford Courier, Mazda B1600 & B1800, Nissan Lil Hustler, Nissan Pickup, and Toyota Hi-Lux. It is a compact truck fitment that reflects the simpler tire sizing used on many small pickups of the era. Product details are not listed here for this exact size, but the application pattern shows its usefulness across several import-based truck platforms. For owners of these light-duty pickups, correct wheel width and intended use are central to selection. A small truck driven lightly may prioritize period appearance, while a regularly used truck may need closer attention to load expectations.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

12-16.5 is a large-section 1977 bias-ply truck size used on the Ford F-350. Available STA blackwall products include Traxion and Transport designs, with listed rim width of 9.75 inches on some examples and maximum load capacity up to 3000 lbs at 45 psi. This is one of the most substantial tire sizes shown for the year and is clearly aimed at heavier-duty work use rather than passenger comfort or styling variety. Because the section width is large and the wheel diameter is 16.5 inches, owners should verify fender clearance, wheel dimensions, and the truck’s actual service role before choosing a replacement.

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

G70-14 is a sporty 1977 bias-ply size used on the Ford GT. Product choices are rich for a single-application size, with Firestone Wide Oval and Goodyear Custom Wide Tread offerings in redline, raised white letter, and pin-white-stripe formats. Listed rim-width ranges generally span 6.0 to 8.0 inches, and some products carry a maximum load capacity of 1620 lbs at 32 psi. This size is especially significant for enthusiasts chasing a true late-1960s to late-1970s performance-tire visual, even on a 1977 application. Sidewall treatment becomes a major styling decision here, not just a minor specification detail.

H70-14 is listed for the 1977 Ford GT and represents a wider, performance-oriented bias-ply size than many ordinary 14-inch passenger fitments of the year. While product details are not shown here for this exact size, its role is clear: it belongs to the muscle- and sport-style side of 1977 fitment rather than economy or standard sedan use. Because performance-styled sizes can vary noticeably in overall section width and stance, this is a fitment that deserves careful wheel and clearance confirmation. Owners should also decide whether they are trying to maintain a more aggressive period profile or align the car with a different documented size option.

DR70-14 is a radial fitment used on the 1977 Ford Granada and Mercury Comet. The “70” profile gives it a lower, sportier appearance than taller alpha-numeric radials such as DR78-14, making it relevant to trim or package differences within similar vehicle families. Product details are not listed here for DR70-14, so this size functions mainly as a fitment identifier rather than a product-rich category. For owners, the important takeaway is that even closely related mid-size domestic cars in 1977 could use different radial profiles. Tire size should be verified at the model and configuration level rather than assumed from platform similarity.

The DR78-14 radial size is used on 1977 Ford Granada, Ford Granada Ghia, Ford Maverick, Mercury Comet, Mercury Monarch, and Plymouth Volare models. It is part of the alpha-numeric domestic radial family and generally carries a taller sidewall profile than 70-series alternatives. Product details are not shown here for this exact size, but it remains an important fitment point for owners of mid-size and compact domestic cars trying to retain a correct-looking 14-inch radial package. Since several of these vehicles also appear with nearby C78-14, D78-14, ER78-14, or FR78-14 fitments, exact model and trim verification is essential.

C78-14 is a bias-ply size listed for the 1977 Ford Maverick. It is one of the smaller domestic alpha-numeric 14-inch applications and reflects a simpler bias-ply fitment path for a compact American sedan. Product details are not shown here for this size, so the main advantage of identifying it is keeping the tire search within the correct period size family. On vehicles like the Maverick, which may also be seen with radial-marked alternatives depending on configuration, owners should confirm whether the goal is to preserve a true bias-ply driving character or maintain compatibility with the car’s current wheel-and-suspension setup.

CR78-14 is a radial fitment used on the 1977 Ford Maverick and Mercury Comet. It sits in the smaller end of the domestic alpha-numeric radial range and offers a distinct alternative to the bias-ply C78-14 size used in related applications. Product details are not listed here for CR78-14, but its importance lies in distinguishing a compact domestic radial setup from larger 14-inch sedan and intermediate sizes. Owners should verify whether the car is documented for this radial fitment rather than another neighboring size. On compact models, small changes in width or profile can have an outsized effect on ride height and wheel-opening appearance.

Rim Diameter: 13 in  ·  Sidewalls: Narrow Whitewall

195/70R13 is used on the 1977 Ford Mustang and Mazda RX-4, making it a relatively uncommon but clearly sporting 13-inch radial application. Compared with 155R13 or 165R13 sizes, it is considerably wider and lower in profile, giving these cars a more assertive stance. The listed product is a BFGoodrich Silvertown Radial with a 7/16-inch narrow whitewall, 13-inch rim fitment, a 5.00 to 6.50-inch rim-width range, and a maximum load capacity of 1246 lbs at 35 psi. This size is especially appropriate for owners who want a period-correct late-1970s sporty look without stepping into a modern oversized conversion.

C78-15 is a bias-ply size used on the 1977 GMC Rally and GMC Vandura. This places it in the van segment rather than the passenger-car mainstream, and it likely reflects a lighter 15-inch fitment within that category. Product details are not listed here for this exact size, so the value of the size guide is in helping owners separate it from larger van sizes such as J78-15 or JR78-15. Because custom van culture often led to wheel changes, surviving examples may no longer wear the documented size. Checking the current wheels and the intended use of the van is essential before selecting a replacement.

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

560-13 is a compact bias-ply size used on the 1977 Honda Accord, Mazda RX-3, Renault Renault, Triumph Spitfire, and Volkswagen Dasher. It serves a diverse group of smaller import cars, many of which could also appear with radial alternatives in adjacent size families. Available bias-ply products include BFGoodrich and Firestone offerings in narrow and wide whitewall styles, with listed rim widths around 3.50 to 4.50 inches and a maximum load capacity of 850 lbs at 30 psi. This size is best suited to owners seeking a distinctly period small-car appearance. Because it is narrow and light-duty, wheel width and overall vehicle weight remain important considerations.

155R12 is a radial fitment listed for the 1977 Honda Civic. This small metric radial size reflects the compact packaging and efficient design of late-1970s subcompact imports. Product details are not listed here for this exact size, but the size itself is important because 12-inch tire applications are less common than 13- or 14-inch fitments in the same year. On a Civic, maintaining the proper diameter and section width helps preserve both stance and drivability. Since some examples may have been converted to 13-inch wheels over time, owners should verify the wheel diameter directly rather than relying solely on model year.

The 6.00-12 size is a bias-ply fitment used on the 1977 Honda Civic. It represents a traditional numeric small-car size that contrasts with the Civic’s also-listed 155R12 radial application. That makes it a useful example of how a single model year could straddle older and newer tire conventions. Product details are not shown here for 6.00-12, so owners should focus first on determining whether their Civic is intended to remain on a bias-ply setup or whether it already uses the radial-marked alternative. Because 12-inch tires are relatively specialized, exact wheel diameter and the car’s current configuration should be confirmed before shopping.

6.15-13 is a bias-ply compact-car size used on the 1977 Honda Civic, Mazda 808, Mazda GLC, Nissan F10, Subaru DL, Subaru GL, and Toyota Corolla. It is a traditional numeric import size that overlaps a group of cars also commonly associated with metric radial alternatives. Product details are not listed here for this exact size, but it remains useful for owners preserving a more period-correct small-car bias-ply look. Because these lightweight models are sensitive to tire height and width, it is worth confirming the actual wheel size and intended construction before making a replacement decision. Bias-ply and radial versions can change both ride and appearance.

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

225/75R15 is listed for the 1977 International Scout II and is one of the year’s more versatile truck-oriented radial sizes with substantial product support. Available offerings include BFGoodrich, Coker Classic, and American Classic radials in both wide and narrow whitewall treatments, with listed rim widths generally from 6.00 to 8.00 inches and load capacities up to 2,094 lbs at 32 psi on some products. This gives Scout owners multiple paths, from a more dressed-up whitewall look to a more restrained radial presentation. Because the Scout II also appears with H78-15 and HR78-15, size selection should be tied to the exact wheel package and intended driving style.

ER70-15 is used on the 1977 Jaguar XJ12C, Jaguar XJ12L, Jaguar XJ6, and Jaguar XJS. This radial size combines a low-profile 70-series shape with a format typical of upscale imported performance and luxury applications of the era. Product details are not listed here for this exact size, but its role is clear within the Jaguar range: it supports the lower, wider stance expected of these cars. Since some Jaguar models in the same year are also associated with 205/70R15, owners should confirm the precise model and current wheel fitment. On these cars, even small size changes can influence both appearance and road manners.

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

This 1977 radial size is used on the Jaguar XJ6, Jaguar XJS, and Maserati Merak, placing it squarely in the premium European grand touring category. Available products include blackwall, narrow whitewall, and wide whitewall options from Maxxis, Michelin, Avon, and American Classic, with listed rim widths generally from 5.00 to 7.50 inches and load capacities up to 1499 lbs at 35 psi. That gives owners the ability to stay close to an understated European look or choose a slightly more decorative sidewall treatment. Because these are specialty applications, the final choice should be based on both fitment accuracy and the vehicle’s intended use rather than visual style alone.

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

600-16 is a traditional bias-ply size used on the 1977 Jeep CJ6. The available product range is broad, including blackwall and wide whitewall tires from BFGoodrich, Coker Classic, Avon, and Firestone, with listed rim widths around 4.00 to 4.50 inches and load capacities up to 1433 lbs on some products. While the CJ6 is a utility vehicle, the size’s product mix shows that a classic 16-inch bias-ply can be tailored toward either a more workmanlike blackwall or a restoration-oriented whitewall presentation. Before selecting a tire, owners should consider whether the Jeep retains its original wheel setup or has been modified for off-road use.

10-15 is a bias-ply size used on the 1977 Jeep Cherokee and Jeep Truck J-10. It falls into the wider 15-inch utility and truck category rather than ordinary passenger-car fitment, and it likely reflects a more substantial section width for Jeep applications. Product details are not shown here for this exact size, so owners should use the size primarily as a fitment identifier while verifying wheel width and vehicle clearance. Older Jeep trucks and SUVs are often modified with suspension, wheel, or axle changes, and those changes can affect whether the original-size family is still the best choice.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

175/70R14 appears on the 1977 Lancia Beta and Mercedes-Benz 280. It is a relatively focused radial application that blends European passenger-car proportions with a lower 70-series profile. The listed product is a Travelstar radial with a 14mm narrow whitewall, giving this size a slightly dressed appearance rather than a plain blackwall-only presentation. This can appeal to owners of imported sedans who want a classic look without leaving the documented size family. Since the Mercedes-Benz 280 is also associated with another 14-inch radial size, and Lancia fitment is more specialized, model-specific confirmation remains important.

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

The 195/60R15 size is listed for the 1977 Lotus Esprit and clearly represents one of the year’s lower-profile performance radial applications. Product choices include BFGoodrich whitewall, redline, and raised white letter variants, plus a blackwall Michelin Primacy 3, with listed rim widths generally from 5.5 to 7.0 inches and load capacities up to 1190 lbs at 35 psi where stated. This size gives an owner several distinct visual directions despite the specialized application. On a car like the Esprit, exact width and profile matter for both stance and clearance, so product selection should be made with close attention to wheel dimensions.

205/60R14 is a radial size used on the 1977 Lotus Esprit. It is a lower-profile specialty fitment that emphasizes width and a short sidewall compared with more common 70-series sizes of the year. Product details are not listed here for this exact size, but the size itself points to a more focused performance application where maintaining the proper proportions matters. Cars like the Esprit can be particularly sensitive to tire profile changes, both visually and functionally. For that reason, owners should verify wheel width, front and rear setup, and current vehicle configuration before moving outside the documented size family.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, RWL

This 1977 radial size is used on the Lotus Esprit and stands out as one of the wider, more performance-oriented fitments of the year. Available blackwall and raised white letter products include M&H Racemaster, Cooper Cobra Radial G/T, and BFGoodrich Radial T/A options, with listed rim widths from 6.5 to 8.5 inches and maximum load capacity of 1642 lbs at 35 psi. That makes 235/60R15 relevant for owners seeking a distinctly assertive rear-fitment look and strong period performance character. As with other specialty sports-car sizes, wheel width and body clearance should be checked carefully before choosing among the available options.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

195/70R15 is used on the 1977 Maserati Merak and serves as a focused European grand touring radial application. The listed product is a Michelin XWX blackwall radial, a well-known period-style fitment choice for higher-end European cars. While product information is limited to a single current listing here, the size itself is valuable because it identifies a narrower 15-inch radial path than the broader 205/70R15 used on some related premium applications. On specialty cars like the Merak, preserving overall diameter, tread width, and sidewall profile can be especially important. Wheel fitment and front-to-rear pairing should both be reviewed before ordering.

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

185/70R14 is a versatile 1977 radial size used on the Mazda COSMO, Nissan 810, Porsche 924, Toyota Celica, and Volvo 264. It occupies a middle ground between narrower import touring sizes and wider performance fitments, making it useful across several European and Japanese passenger cars. Current options include BFGoodrich, Avon, Dunlop, and Michelin products in both blackwall and wide whitewall styles, with listed rim widths generally from 4.5 to 6.5 inches and load capacities up to 1235 lbs where specified. This size gives owners flexibility to emphasize either clean touring-car presentation or a slightly more decorative period look.

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

735-14 is a bias-ply size listed for the 1977 Mazda Truck Rotary Truck. Available BFGoodrich classic bias-ply products include blackwall and 1.00-inch narrow whitewall versions, with listed rim widths of 5.00 to 5.50 inches and a maximum load capacity of 1360 lbs at 32 psi. This size is interesting because it supports a specialized truck application while still offering a choice between utility-oriented and more styled sidewall appearances. For owners of the Rotary Truck, the key consideration is preserving the proper 14-inch numeric bias-ply fitment character. Wheel width and actual vehicle use should still be checked before selecting between the available versions.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

Used across 1977 Mercedes-Benz, Peugeot, Toyota, and Volvo applications, 175R14 is a classic metric radial size for imported sedans and coupes. It appears on the Mercedes-Benz 230, Mercedes-Benz 240, Mercedes-Benz 300, Peugeot 504, Peugeot 604, Toyota Celica, Toyota Corona, and Volvo DL. Current blackwall options include Michelin XAS and Vredestein Sprint lines, with listed rim widths generally from 4.5 to 6.0 inches and load capacities up to 1,235 lbs where stated. This size is particularly well suited to owners who want a period-European touring feel. Because it spans several makes, the exact model and wheel setup should still guide final selection.

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

185R14 is one of the more broadly used 1977 import radial sizes, covering Mercedes-Benz, Nissan, Peugeot, Toyota, Volkswagen, and Volvo applications. It appears on models such as the Mercedes-Benz 280, Nissan Pickup, Peugeot 504, Toyota Pickup, Volkswagen Campmobile, Volkswagen Kombi, Volkswagen Van Delivery Van, Volvo 265, and Volvo DL. Available products include blackwall and narrow whitewall radials from Michelin, Phoenix, and Vredestein, with listed rim widths generally from 4.0 to 6.5 inches and load capacities up to 1323 lbs where specified. Since this size spans passenger cars, pickups, and vans, exact vehicle role and wheel dimensions matter when choosing among the available styles.

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

215/70R14 is a radial fitment listed for the 1977 Mercedes-Benz 6.9. It is one of the year’s more substantial 14-inch passenger-car sizes and aligns with a large-displacement luxury-performance application. Current offerings include blackwall, raised white letter, pin-white-stripe, and narrow whitewall products from Cooper, Michelin, BFGoodrich, and Maxxis, with listed rim widths typically from 5.5 to 7.5 inches and load capacities up to 1554 lbs at 35 psi. This gives buyers several ways to tailor appearance while remaining in the correct size family. On a specialty sedan of this type, wheel width and the desired balance of originality-minded style versus general road use are important selection factors.

165/70R13 is a radial size used on the 1977 Nissan F10. Compared with taller 155R13 or 165R13 sizes, it has a shorter sidewall and a more modern small-car profile. Product details are not listed here for this exact size, but the format itself is helpful because it separates the F10’s lower-profile fitment from more traditional compact import sizes. That distinction matters when trying to preserve the car’s intended stance and handling character. Since the Nissan F10 is also associated with other 13-inch sizes, owners should check the exact sidewall marking and confirm whether the vehicle still retains the correct wheel package before shopping.

6.45-13 is a bias-ply size used on the 1977 Nissan PL610 and Nissan PL710. It reflects a traditional compact-car numeric fitment and sits alongside metric radial alternatives in the broader late-1970s import market. Product details are not listed here for this exact size, so this application is best understood as a period-correct size marker for these Nissan sedans. If the vehicle is being restored with an emphasis on original-type appearance, keeping the numeric bias-ply format may be important. If the car has already been updated with different wheels or radial sizes, owners should inspect the existing setup carefully before choosing a replacement.

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

185/70R15 is used on the 1977 Porsche 911 and represents a focused 15-inch radial sports-car fitment. Available products include blackwall offerings from Michelin, Dunlop, and Avon, along with a BFGoodrich Silvertown Radial 2.25-inch wide whitewall, with listed rim widths generally from 4.5 to 6.5 inches and load capacities up to 1279 lbs where specified. This size gives owners a choice between a more traditional European blackwall appearance and a somewhat more stylized period sidewall treatment. On a rear-engine sports car, maintaining the intended size family is especially important, so wheel width and the car’s current chassis setup should be confirmed before ordering.

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

The 205/55R16 size is used on the 1977 Porsche 930 and stands among the most modern-looking fitments in this year guide. It is a low-profile 16-inch radial size associated with a high-performance application where width, diameter, and handling response are all significant. Current blackwall options include BFGoodrich g-Force variants and Michelin SX MXX3, with listed rim widths from 5.5 to 7.5 inches and load capacities up to 1477 lbs where specified. This is not a general replacement category for ordinary 16-inch cars. On a specialty performance model, owners should confirm wheel size, front-versus-rear application, and overall setup before selecting a tire.

Rim Diameter: 16 in  ·  Sidewalls: Blackwall

225/50R16 is another 1977 Porsche 930 fitment and represents an even wider low-profile radial than 205/55R16. Available blackwall products include BFGoodrich g-Force and Michelin Pilot Sport options, with listed rim widths from 6.0 to 8.0 inches and load capacities up to 1389 lbs where stated. This size clearly belongs to a specialized performance context rather than the mainstream late-1970s passenger-car market. Because the 930 uses a staggered, high-performance tire strategy, this size should be selected with close attention to wheel width and position on the car. Tire choice here is about preserving the proper performance fitment, not simply matching diameter.

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

235/70R15 is a large radial size used on the 1977 Rolls Royce Camargue and Rolls Royce Corniche. It provides a substantial 15-inch luxury-car fitment with a broad footprint and a taller sidewall than performance-oriented 60-series sizes. Current products include Cooper, Avon, BFGoodrich, and Michelin offerings in blackwall, raised white letter, and redline forms, with listed rim widths generally from 6.0 to 8.5 inches and load capacities up to 1896 lbs at 35 psi on some products. For cars of this type, overall ride character and visual proportion matter as much as size itself. Buyers should weigh sidewall appearance carefully while confirming wheel compatibility.

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

165R15 is a classic metric radial size used on the 1977 Saab 99 and Volkswagen Beetle. It is a tall, relatively narrow radial well suited to compact European applications that benefit from correct overall diameter and modest tread width. Product support is strong, with blackwall, narrow whitewall, and wide whitewall choices from Coker Classic, American Classic, Firestone, and BFGoodrich, plus listed rim widths from 4.50 to 6.00 inches and load capacities around 1168 to 1170 lbs where specified. This size gives owners considerable flexibility in appearance while preserving the basic fitment character of these cars. Wheel width still deserves confirmation before ordering.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

175/70R15 is a radial size listed for the 1977 Saab 99. Compared with 165R15, it offers a lower profile and slightly broader section, making it an important distinction within the same model line. Available blackwall options include Avon CR6ZZ and Vredestein Sprint Classic, with listed rim widths from 4.5 to 6.0 inches and load capacity up to 1,168 lbs at 51 psi where specified. This size is best suited to owners wanting a clean European-style appearance and a more sporting 15-inch profile. Since Saab 99 applications can vary, the sidewall marking and wheel setup should be confirmed before choosing between different 15-inch fitment paths.

B78-14 is a bias-ply size used on the 1977 Toyota Corona. It is a relatively uncommon compact-car domestic-style alpha-numeric fitment in a year where many imports were already using metric radial sizes. Product details are not listed here for this exact size, but the size is still useful because it highlights a distinct fitment path for a model that also appears within broader import sizing trends. On a Corona, preserving the intended stance and wheel fitment matters more than forcing interchange with a nearby metric radial. Owners should inspect the wheel size and current tire markings carefully before selecting a replacement.

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

750-14 is a numeric bias-ply size used on the 1977 Toyota Pickup. Available products include BFGoodrich, US Royal, and Coker Classic tires in narrow whitewall, wide whitewall, and redline styles, with listed rim widths from 5.00 to 5.50 inches and load capacities up to 1580 lbs at 32 psi. This is a useful size for owners who want a small truck tire with strong period styling flexibility. A narrow whitewall can suit a light-duty dressed pickup, while blackwall-adjacent styling choices may better fit a working vehicle. Even with good product coverage, wheel width and actual pickup configuration should still be checked first.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

185R13 is a radial fitment listed for the 1977 Triumph TR7. It is a taller-profile 13-inch metric radial that differs notably from the lower 185/70R13 applications seen elsewhere in the same year. The current listing is a Michelin XAS-FF blackwall radial, reinforcing the size’s European sports-car character. Because the TR7 is also associated with 185/70R13, confirming which fitment applies to the specific car is especially important. A change between 80-series and 70-series profiles can alter both the appearance and effective gearing feel. Wheel dimensions and the car’s current ride height should be reviewed before making a final choice.

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

600-15 is a bias-ply size used on the 1977 Volkswagen Beetle. It is a traditional numeric fitment that offers a distinctly period look compared with the Beetle’s also-listed 165R15 radial application. Available BFGoodrich classic bias-ply products include blackwall and 2.625-inch wide whitewall versions, with listed rim widths around 4.00 to 5.00 inches and a maximum load capacity of 1150 lbs at 32 psi. This size is especially relevant for restorers who want a more vintage driving character and appearance. Since many Beetles have been converted between bias-ply and radial fitments over the years, checking the current wheel and tire setup is worthwhile.

155D13 is a bias-ply size listed for the 1977 Volkswagen Rabbit. The “D” construction marking distinguishes it from radial sizes such as 155R13 and 155/80R13 that also appear on late-1970s compacts. Product details are not shown here for this exact size, but it remains useful as a reminder that some small imported cars straddled both bias-ply and radial fitment conventions during this period. On a Rabbit, the difference in construction can influence ride feel and visual profile. Owners should verify the wheel size and decide whether the goal is to preserve a documented bias-ply application or maintain the car’s current radial-based setup.
