1978 Vehicle Tire Fitment Guide

Rim Diameter: 14 in  ·  Sidewalls: Wide Whitewall

H78-14 is a larger bias-ply 14-inch size used on the 1978 American Motors Matador, Chevrolet El Camino, Ford 500/Squire, and GMC Sprint. In this year, it bridges full-size passenger-car and coupe-utility applications, making careful fitment confirmation especially important. Product coverage includes a Coker Classic Bias Ply with a 2.50-inch whitewall for 14-inch rims and 5.50- to 8.00-inch rim widths, carrying a stated maximum load of 1770 pounds at 32 psi. Owners researching H78-14 often balance period-correct visual style with the broader footprint expected on larger late-1970s vehicles.

HR78-14 is a radial size used on select 1978 American Motors, Ford, and Mercury applications, including the American Motors Matador, Ford 500/Squire, Ford GT, Ford LTD, and Mercury Cougar. This alpha-numeric radial format was common during the transition from bias-ply to radial tires on larger domestic cars and personal-luxury models. Because these vehicles differ substantially in wheelbase, weight, and intended driving character, the important step is not just matching HR78-14, but also confirming whether the vehicle is being restored to a period look or maintained for regular road use.

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

E78-14 is a bias-ply size with wide 1978 use across domestic cars and light trucks, including the American Motors Pacer, Buick Skylark, Chevrolet Luv Pickup, Chevrolet Nova, Dodge Aspen, Nissan Pickup, Oldsmobile Omega, Plymouth Volare, and Pontiac Phoenix. Product choices show that this size can serve different needs: a Coker Classic wide whitewall for a passenger-car presentation, an STA Traxion 8 Ply Rated Tubeless tire for heavier-duty use, and an STA Transport Highway truck-oriented option. That variety makes application and intended use especially important when selecting an E78-14 tire.

ER78-14 is a radial size used on several compact and intermediate 1978 domestic cars, including the American Motors Pacer, Buick Skylark, Dodge Aspen, Ford Granada, Mercury Monarch, Oldsmobile Omega, Plymouth Volare, and Pontiac Phoenix. It reflects the late-1970s move toward radial construction while keeping the domestic alpha-numeric sizing format familiar to the period. Since many of these same model families also appear with neighboring bias-ply sizes, ER78-14 is best treated as a specific fitment rather than a general substitute. Wheel width, overall stance, and restoration goals all matter here.

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

GR70-15 is a sporty 15-inch radial fitment used on the 1978 Aston Martin AM, Buick LeSabre, Chevrolet Camaro, and Pontiac Firebird. The mix of luxury and performance applications makes this one of the more visually style-sensitive sizes for the year. Available products include Goodyear bias-look radial choices in the GM Custom Tread, Steelgard, and Custom Wide Tread families, with both pin-white-stripe and raised white letter sidewall styles. Listed rim-width ranges include 7.0 to 8.0 inches on several products, making GR70-15 especially relevant for owners chasing a strong period performance appearance.

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

185/70R14 is a radial metric size used on a range of 1978 European and import-oriented cars, including the Audi 5000, Mazda COSMO, Nissan 810, Porsche 924, Toyota Celica, Volvo 242, Volvo 262, and Volvo 264. Compared with domestic alpha-numeric sizes, this format gives a more modern metric reference common on imported sedans and coupes of the period. Product choices include wide whitewall and blackwall options from BFGoodrich, Avon, Dunlop, and Michelin, with listed rim-width ranges as narrow as 4.5 to 6.5 inches depending on the product.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

155R13 is one of the most widely shared small-car radial sizes of the 1978 model year, appearing on vehicles such as the Audi Fox, Fiat 128, Honda Accord, Honda Civic, Mazda GLC, Mazda RX-3, Nissan 210, Nissan F10, Opel Opel, Subaru DL, Subaru GL, Toyota Corolla, Triumph Spitfire, Volkswagen Base, and Volkswagen Rabbit. This 80-series metric radial format is typical of small imports and economy cars from the era. Available blackwall products from Michelin and Dunlop make it a practical choice for owners seeking a road-ready radial with a distinctly period small-car fitment profile.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

175/70R13 is a radial low-profile metric size associated with several 1978 compacts and sporty small cars, including the Audi Fox, Mazda GLC, Nissan 200, Nissan 210, Opel Opel, Volkswagen Base, and Volkswagen Scirocco. In period context, this size reflects the growing use of lower-profile radial tires on imports that emphasized more responsive handling than traditional 80-series fitments. Current product coverage includes an Avon CR6ZZ blackwall radial with a listed rim-width range of 4.5 to 6.0 inches, making it especially appealing for drivers wanting a performance-oriented vintage import presentation.

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

185/70R13 is a radial size used on a mix of sporty and upscale 1978 applications including the BMW 320i & 320iA, Lotus Elite, Plymouth Arrow, Toyota Corolla, Triumph TR7, and Triumph TR8. This metric radial format has a notably broad character, covering everything from German sedans to British sports cars. Product choices include blackwall, wide whitewall, and redline treatments from BFGoodrich, Avon, and Dunlop. Listed rim-width ranges generally fall between 4.5 and 6.5 inches, so wheel width and the intended period look can make a meaningful difference in final selection.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

195/70R14 is a radial size used on 1978 cars such as the BMW 530i & 530iA, BMW 633 CSi & CSiA, Dodge Challenger, Mercedes-Benz 300, Nissan 280Z, and Plymouth Sapporo. It is a strong example of late-1970s metric radial fitment appearing across European luxury sedans, sporting coupes, and import-influenced domestic models. Current product coverage is centered on a Dunlop Sport Classic blackwall radial, which makes this size particularly straightforward for shoppers prioritizing a clean, era-appropriate performance appearance rather than multiple sidewall styling choices.

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

205/70R14 is one of the more broadly used radial sizes for 1978, appearing on vehicles including the BMW 733i, Buick Century, Buick Regal, Chevrolet Monte Carlo, Ferrari 308, Lotus Esprit, Mercedes-Benz 450, Oldsmobile Cutlass, Pontiac Grand Am, Pontiac Grand LeMans, Pontiac Grand Prix, and Pontiac LeMans. That spread covers luxury, personal-luxury, and sports-car applications. Product options include narrow whitewall, raised white letter, redline, and dual redline styles from Maxxis and BFGoodrich, with listed rim-width ranges from 5.00 to 7.50 inches depending on the tire.

Rim Diameter: 390mm in  ·  Sidewalls: Blackwall

220/55R390 is a specialized radial size used only on the 1978 BMW 733i. Unlike standard inch-based rim diameters, this fitment uses a 390mm wheel specification, so it cannot be treated like an ordinary 15-inch or 16-inch tire size. Product coverage includes a Michelin TRX-B blackwall radial with listed 390mm rim diameter compatibility and rim widths of 135mm, 150mm, and 180mm. For owners of a 1978 BMW 733i, this size deserves especially careful wheel confirmation because the TRX system is distinct from conventional bead-seat dimensions.

HR70-15 is a radial size used on premium 1978 applications including the Bentley T2 Series, Ford Thunderbird, Mercury Cougar, and Rolls Royce Silver Shadow. It reflects the era’s larger touring and personal-luxury fitments, where sidewall profile and overall appearance matter almost as much as the construction type. Although product details are not listed here for every possible styling variation, HR70-15 should be selected with attention to the vehicle’s wheel width, trim level, and intended use. It is not a generic 15-inch replacement, especially across such different luxury platforms.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

185/75R14 is a radial size shared by several 1978 mid-size domestic cars, including the Buick Century, Chevrolet Malibu, Oldsmobile Cutlass, Pontiac Grand LeMans, and Pontiac LeMans. This metric radial format was common on practical family coupes and sedans where ride comfort and balanced proportions were priorities. Product availability leans toward whitewall styles, with narrow whitewall choices from Tornel, Maxxis, and Travelstar. Listed rim widths vary by product, generally covering 4.50- to 7.50-inch applications, so it is a useful size for owners seeking a distinctly late-1970s passenger-car look.

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

195/75R14 is a radial fitment used on 1978 mid-size domestic cars including the Buick Century, Buick Regal, Chevrolet Malibu, Oldsmobile Cutlass, Pontiac Grand LeMans, Pontiac Grand Prix, and Pontiac LeMans. It represents a slightly larger passenger-car radial than 185/75R14 while keeping the same basic 14-inch format. Product choices include both narrow and wide whitewall treatments from Coker Classic, Tornel, and Maxxis, making it especially flexible for restorers and drivers who want to tune the car’s visual character without changing the core fitment size.

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

205/75R14 is a radial size associated with the 1978 Buick Century, Buick Regal, and GMC Caballero. Its use on both passenger cars and a coupe-utility application makes it a size where intended use should guide product choice. Available tires include narrow and wide whitewall options from American Classic, Coker Classic, and Maxxis, with listed rim-width compatibility extending from roughly 5.00 to 7.50 inches depending on the model. For 1978 vehicle tire fitment, 205/75R14 offers a useful blend of late-1970s whitewall styling choices and practical radial construction.

GR78-15 is one of the most widely shared radial sizes in 1978, used across full-size domestic cars, pickups, and vans from Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Nissan, Oldsmobile, and Pontiac. This broad application range means the size alone is only the starting point. A GR78-15 tire selected for a Buick Electra may emphasize a very different look than one chosen for a Chevrolet C/K Pickup. Shoppers should confirm the exact vehicle and wheel setup, then compare sidewall style and construction details within the products available for this size.

HR78-15 is another major 1978 radial size, appearing on a very wide mix of full-size cars, wagons, utilities, and trucks from Buick, Cadillac, Checker, Chevrolet, Chrysler, Dodge, Ford, GMC, International, Jeep, Mercury, Oldsmobile, and Pontiac. It is especially common where larger domestic vehicles needed a substantial 15-inch tire footprint. Because the size serves everything from a Cadillac Fleetwood Brougham to a Jeep Cherokee, owners should not assume the same visual style or load needs across every application. Exact vehicle use and overall tire character matter as much as the designation itself.

FR78-15 is a radial 15-inch size used on a variety of 1978 domestic passenger cars and vans, including Buick LeSabre, Chevrolet Chevrolet, Chevrolet Van Van, Chrysler Cordoba, Chrysler LeBaron, Dodge Charger, Dodge Diplomat, Dodge Magnum XE, GMC Rally, GMC Vandura, Oldsmobile Delta 88, Oldsmobile Omega, Pontiac Bonneville, Pontiac Catalina, Pontiac Esprit, and Pontiac Firebird. This wide spread covers everything from formal sedans to sporty personal cars. It is best selected with attention to vehicle stance and style goals, since sidewall presentation can strongly influence the finished period look.

BR70-13 is a radial alpha-numeric size used on compact sporty 1978 cars including the Buick Skyhawk, Chevrolet Monza, Ford Mustang, Mazda RX-4, and Oldsmobile Starfire. This size reflects the era’s move toward lower-profile tires on smaller rear-wheel-drive performance-oriented models. While detailed product coverage is not shown here for this size, BR70-13 should be viewed as a specialty compact performance fitment rather than a general small-car radial. Wheel width, wheel diameter, and the intended late-1970s appearance all deserve confirmation before selecting a tire.

BR78-13 is a radial size used on several smaller 1978 domestic compacts, including the Buick Skyhawk, Chevrolet Monza, Ford Mustang, Ford Pinto, Mercury Bobcat, and Pontiac Sunbird. It sits within the familiar alpha-numeric radial system that was common during the decade’s gradual fitment changeover. Compared with pure bias-ply compact sizes, BR78-13 offers a radial construction profile while still looking period-appropriate on many late-1970s cars. Because some of these same models also used A78-13 or B78-13, confirming the exact tire size on the vehicle remains essential.

B78-13 is a bias-ply compact-car size used on the 1978 Buick Skyhawk, Chevrolet Monza, Ford Mustang, Mercury Bobcat, Oldsmobile Starfire, and Pontiac Sunbird. It is a strong period-correct style fitment for smaller domestic coupes and hatchbacks that were offered with traditional 13-inch bias-ply tires. Since these model lines often overlap with radial alternatives such as BR70-13 or BR78-13, B78-13 should be chosen only after confirming whether the vehicle is still on its original-type wheel setup or has been updated over time.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall

LR78-15 is a larger radial size used on 1978 vehicles ranging from the Cadillac Eldorado and Lincoln Continental to pickups, Suburbans, full-size wagons, and vans from Chevrolet, Dodge, Ford, GMC, Mercury, and others. This is not a light-duty passenger-car fitment in the usual sense, and the vehicles sharing it vary greatly in weight and intended use. Product coverage includes a Firestone Steel Belted 721 bias-look radial with a narrow whitewall, listed for 15-inch rims, 5.50- to 8.00-inch rim widths, and a maximum load of 1970 pounds at 32 psi.

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

G78-15 is a bias-ply 15-inch size used on 1978 cars, pickups, vans, and utility vehicles from Checker, Dodge, Ford, Nissan, and Plymouth. It appears on everything from the Checker Marathon & Taxi and Plymouth Fury to Dodge Ramcharger and Ford F-100 applications. Product options show two very different directions: Coker Classic wide whitewall tires for a traditional passenger-vehicle presentation and an STA Super Traxion blackwall for truck-oriented use. That makes G78-15 a size where the same designation can support very different appearance and service goals.

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

700-15 is a traditional numeric bias-ply size with broad 1978 use on utility vehicles and light trucks, including the Chevrolet Blazer, Chevrolet C/K Pickup, Chevrolet Suburban, Dodge Pickup, Dodge Ramcharger, Ford Bronco, Ford F-100, Ford F-150, GMC C/K Pickup, GMC Jimmy, GMC Suburban, Plymouth Trailduster, and Plymouth Wagon. Available products include blackwall and wide whitewall passenger-style bias tires from Firestone and BFGoodrich, plus an STA Traxion blackwall truck tire. That mix gives owners room to prioritize either a classic SUV look or a more work-oriented tire presentation.

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

H78-15 is a bias-ply 15-inch size found on many 1978 trucks, vans, SUVs, and some full-size cars, including the Chevrolet Blazer, Dodge Ramcharger, Ford Bronco, GMC Jimmy, International Scout II, Jeep CJ models, Jeep Cherokee, Plymouth Fury, and more. Product choices include Coker Classic wide whitewall versions and an STA Traxion blackwall with a stated maximum load of 1830 pounds at 45 psi. Because H78-15 crosses over from passenger-style to utility applications, buyers should pay attention not just to size, but also to sidewall style and service character.

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

L78-15 is a larger bias-ply size used on numerous 1978 trucks, wagons, and sport-utility vehicles, including the Chevrolet Blazer, Chevrolet C/K Pickup, Chevrolet Suburban, Dodge Pickup, Dodge Ramcharger, Ford Bronco, Ford F-100, Ford F-150, GMC C/K Pickup, GMC Jimmy, GMC Suburban, Plymouth Trailduster, and Plymouth Wagon. Product options include blackwall, narrow whitewall, and wide whitewall bias-ply tires from Coker Classic and BFGoodrich, all on 15-inch rims. Listed maximum load capacity reaches 1970 pounds at 32 psi on several products, reinforcing its larger-duty role.

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

650-16 is a bias-ply 16-inch truck size used on the 1978 Chevrolet C/K Pickup and GMC C/K Pickup. This traditional numeric format is associated with heavier light-truck service and should be matched carefully to wheel size and intended use. Product coverage is unusually broad, with blackwall and wide whitewall options from BFGoodrich, Coker Classic, Firestone, and Garfield. Listed rim widths include 4.50 to 5.00 inches on several tires, and stated load capacities reach 1580 pounds at 32 psi. It is a practical size for owners balancing truck utility with period visual style.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

875-16.5 is a bias-ply truck and van size used across many 1978 heavy-duty applications, including Chevrolet and GMC pickups and vans, Dodge commercial models, Ford F-250 and F-350 lines, and the Jeep Truck J-20. The 16.5-inch rim diameter makes this a specialized fitment that cannot be mixed with 16-inch tires. Product options are blackwall STA Traxion and STA Transport Highway tires, both aimed at truck-oriented service. For 1978 heavy-duty fitment, the key considerations are exact wheel diameter, load needs, and whether the vehicle remains in stock configuration.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

950-16.5 is a larger bias-ply truck size used on 1978 heavy-duty pickups, vans, and utility vehicles such as the Chevrolet C/K Pickup, Chevrolet Suburban, Dodge Pickup, Dodge vans, Ford F-250, Ford F-350, Ford E-350 Econoline Van, GMC C/K Pickup, GMC Suburban, and Jeep Truck J-20. Available products include STA Traxion and STA Super Transport blackwalls, both with listed 16.5-inch rim diameter, 6.50- to 6.75-inch rim widths, and maximum load capacities of 2780 pounds at 60 psi. This is a clear example of a load-focused fitment where wheel and duty-cycle verification are essential.

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

750-16 is a bias-ply 16-inch size used on 1978 heavier-duty truck and utility applications including the Chevrolet C/K Pickup, Chevrolet Suburban, Dodge Pickup, Ford F-250, GMC C/K Pickup, GMC Suburban, and Jeep Truck J-20. Product coverage includes blackwall and wide whitewall tires from Firestone, Lester, and BFGoodrich. Listed rim widths generally fall in the 5.00- to 6.00-inch range, with stated load capacities varying by product, including up to 1850 pounds at 48 psi on one BFGoodrich option. It is a useful size for combining classic truck style with traditional commercial-duty sizing.

8.75R16.5 is a radial heavy-duty truck and van size used on many 1978 commercial and utility applications from Chevrolet, Dodge, Ford, and GMC. It appears on models such as the Chevrolet C/K Pickup, Chevrolet Suburban, Ford F-250, Ford F-350, and GMC Rally, among others. The radial construction distinguishes it from neighboring 16.5-inch bias-ply sizes, but it still requires a true 16.5-inch wheel. For owners comparing heavy-duty 1978 vehicle tire fitment, this size highlights the importance of matching both construction type and exact bead-seat diameter before ordering.

8.75-16 is a bias-ply truck size used on the 1978 Chevrolet C/K Pickup and GMC C/K Pickup. It is a traditional heavy-duty numeric format and should not be confused with 8.75R16.5, which differs in both construction notation and rim diameter. This size points to a more work-oriented pickup application where load handling and wheel compatibility take priority over passenger-car styling concerns. Because product details are not listed here for this specific size, careful measurement and confirmation of the existing wheels are especially important when replacing tires on surviving trucks.

10-15 is a bias-ply utility and truck size used on the 1978 Chevrolet C/K Pickup, GMC C/K Pickup, Jeep Cherokee, and Jeep Truck J-10. This size belongs to a heavier-duty tire tradition often seen on 4x4 and work-oriented vehicles of the period. Its broad section and utility-focused character make it very different from ordinary passenger-car 15-inch fitments. Because it appears on both full-size pickups and Jeep utility models, owners should verify wheel width, clearance, and any suspension changes before treating 10-15 as a direct replacement choice.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

10-16.5 is a bias-ply heavy-duty size used on the 1978 Chevrolet C/K Pickup and GMC C/K Pickup. Product coverage includes an STA Traxion blackwall tire with a listed 16.5-inch rim diameter, 8.25-inch rim width, and maximum load capacity of 2680 pounds at 60 psi. This size is clearly aimed at truck service rather than passenger use, and its 16.5-inch wheel requirement is critical. On restored or modified pickups, it is wise to confirm that the truck still carries the correct wheel type before selecting a replacement.

155/80D13 is a bias-ply size used on the 1978 Chevrolet Chevette. The D designation identifies a bias construction rather than a radial, making it an important distinction on a small car that was also offered in radial fitment. For owners researching Chevette tires, this size reflects the lower end of late-1970s compact sizing and should be matched carefully to the car’s actual wheel and trim configuration. It is a good example of how one 1978 model could straddle both older and newer tire construction choices.

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

155/80R13 is a small radial size used on the 1978 Chevrolet Chevette, Dodge Omni, Plymouth Horizon, and Volkswagen Rabbit. This is a practical compact-car metric radial format that became increasingly common as front-wheel-drive and economy-focused cars spread through the market. Product options include narrow and wide whitewall styles from Travelstar, BFGoodrich, Maxxis, and Tornel, giving this modest size more visual variety than many import blackwall fitments. Listed rim-width compatibility typically falls between 4.00 and 5.50 inches, depending on the tire chosen.

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

225/70R15 is a radial size associated in 1978 with the Chevrolet Corvette and Pontiac Firebird. That immediately gives it a more performance-oriented identity than many of the year’s full-size sedan fitments. Product selection supports that character, with blackwall and raised white letter choices from Goodyear, Cooper, and Michelin, including Goodyear Polysteel and Cooper Cobra Radial G/T offerings. Listed rim-width recommendations range from 6.0 to 8.0 inches depending on the product, so wheel selection and stance play a major role in choosing the right 225/70R15 tire.

Rim Diameter: 15 in  ·  Sidewalls: OWL, RWL

255/60R15 is a wide radial size used only on the 1978 Chevrolet Corvette. Compared with many other 1978 fitments, this is a distinctly performance-focused size with a lower profile and broader tread footprint. Current choices include OWL and RWL sidewall treatments from Goodyear, Cooper, and BFGoodrich, including Eagle GT, Cobra Radial G/T, and Radial T/A options. Listed rim-width compatibility generally spans 7.0 to 9.0 inches, which makes wheel correctness especially important. This is a size where appearance, handling intent, and wheel width all need to line up.

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

G70-14 is a bias-ply performance-style size used on the 1978 Chevrolet El Camino, Ford GT, and GMC Sprint. It belongs to the era of sporty domestic alpha-numeric performance tires and is strongly associated with sidewall styling choices. Available products include redline, raised white letter, and pin-white-stripe Firestone Wide Oval and Goodyear Custom Wide Tread options, with listed rim-width ranges around 6.0 to 8.0 inches depending on the tire. For owners aiming at a recognizable late-1970s performance look, G70-14 offers some of the most distinctive presentation choices.

GR70-14 is a radial size used on the 1978 Chevrolet El Camino and GMC Sprint. It represents the radial counterpart to period performance-oriented domestic sizing, giving these coupe-utility models a more modern construction while staying within the visual language of the time. Because it is tied to only two closely related applications, GR70-14 is more focused than many shared late-1970s sizes. Owners comparing options should pay attention to whether the vehicle is being kept near stock specification or has been altered with different wheels or suspension components.

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

F70-14 is a bias-ply performance-style 14-inch size used on the 1978 Chevrolet Luv Pickup. Product choices include Firestone Wide Oval and Goodyear Custom Wide Tread versions in pin-white-stripe, redline, and raised white letter formats. Listed rim-width ranges generally fall between 6.0 and 7.0 inches, with maximum load capacities around 1500 pounds at 32 psi on several options. This combination makes F70-14 especially appealing for a pickup owner pursuing a strong period custom or sporty look rather than a plain utility-oriented replacement tire.

A78-13 is a bias-ply compact-car size used on the 1978 Chevrolet Monza, Ford Pinto, Mercury Bobcat, Oldsmobile Starfire, and Pontiac Sunbird. It is one of the smaller domestic alpha-numeric fitments of the year and suits period-style restoration of lightweight rear-wheel-drive compacts. Since these model families often overlap with B78-13 or BR78-13 sizes, A78-13 should be confirmed carefully against the vehicle’s exact configuration. It is best understood as a true late-1970s compact bias-ply fitment, not a general substitute for every 13-inch tire used on these cars.

9.50R16.5 is a radial heavy-duty size used on the 1978 Chevrolet Suburban, Dodge Pickup, and GMC Suburban. As a radial 16.5-inch application, it occupies a different place from neighboring bias-ply truck sizes and must be matched to the proper wheel diameter. This fitment points to larger truck and utility use where load support and highway road manners both matter. Because it appears on vehicles that are frequently modified for towing, off-road use, or cosmetic restoration, wheel width and fender clearance deserve confirmation before replacement.

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

700-16 is a bias-ply truck size used on the 1978 Chevrolet Suburban and GMC Suburban. Product choices include blackwall and wide whitewall offerings from Lester, Avon, BFGoodrich, and Firestone, making this a notably flexible size for a utility vehicle. Listed rim widths generally center on 4.50 to 5.50 inches, while stated load capacities reach as high as 1900 pounds at 36 psi on one BFGoodrich option. That allows 700-16 to support either a work-truck visual theme or a cleaner restoration-oriented appearance, depending on the sidewall chosen.

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

J78-15 is a bias-ply 15-inch size used on the 1978 Chevrolet Van Sportvan, Chevrolet Van Van, GMC Rally, and GMC Vandura. This is a larger van-oriented passenger/utility fitment, and the available product range reflects a styling emphasis rather than off-road use. Current choices include BFGoodrich narrow whitewall and dual white stripe versions, both listed for 15-inch rims and 5.50- to 7.00-inch rim widths, with maximum load capacity of 1860 pounds at 32 psi. It is a useful size for owners who want a distinctly late-1970s van sidewall look.

JR78-15 is a radial size used on a broad set of 1978 full-size cars, luxury coupes, wagons, and vans, including Chrysler New Yorker, Ford Custom 500, Ford LTD, Lincoln Continental, Mercury Grand Marquis, Mercury Marquis, Oldsmobile Toronado, and several Chevrolet, Ford, and GMC van models. This size bridges formal passenger-car and multi-passenger utility applications. That means the same designation may be paired with very different visual expectations, from luxury whitewall presentation to more understated van use, so size confirmation alone is not enough for final tire selection.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

800-16.5 is a bias-ply heavy-duty truck and van size used on many 1978 utility applications, including Dodge pickups and vans, Ford F-250 and F-350 models, Chevrolet and GMC vans, the Jeep Truck J-20, and the Plymouth Wagon. Product options include STA Super Transport and STA Traxion blackwalls. One listed product shows a 16.5-inch rim diameter with 6.00- to 6.50-inch rim widths and a maximum load capacity of 2045 pounds at 60 psi. This is a practical service-oriented size where wheel diameter and load demands are the key purchasing considerations.

F78-15 is a bias-ply size used on the 1978 Dodge Monaco, Dodge Sportsman Wagon, Dodge Van Compact Van, Dodge Van Tradesman Van, Ford F-100, Ford Van E-100 Econoline Van, Jeep CJ5 & CJ7, Jeep CJ6, Plymouth Fury, and Plymouth Wagon. Its vehicle spread is unusually broad, covering full-size passenger cars, vans, pickups, and open utility models. That makes F78-15 a fitment where intended appearance and service type matter. A CJ6 and a full-size Plymouth sedan may share the size designation, but they may call for very different tire character.

165/75R13 is a radial size used on the 1978 Dodge Omni and Plymouth Horizon. This compact metric fitment is closely tied to small front-wheel-drive domestic hatchbacks of the period and is more specific than many of the larger shared domestic sizes from the same year. Because it appears on just these two closely related models, it offers a focused path for shoppers comparing tire choices for practical late-1970s compact transportation. Fitment still depends on the actual wheel and any updates made during the car’s life.

8.00R16.5 is a radial heavy-duty size used on the 1978 Dodge Pickup, Ford E-250 Club Wagon, and Ford Van E-250 Econoline Van. This is a commercial-style fitment where the 16.5-inch rim diameter is a defining specification. Its use on both pickups and larger van applications makes it important to verify wheel type and service demands before ordering. Unlike smaller passenger radial sizes from 1978, this one is primarily about matching the correct heavy-duty wheel and maintaining appropriate load-carrying capability for the vehicle’s intended role.

E78-15 is a bias-ply size used on the 1978 Dodge Ramcharger, Dodge Sportsman Wagon, Dodge Van Compact Van, Dodge Van Tradesman Van, Plymouth Trailduster, and Plymouth Wagon. This fitment appears mainly on utility vehicles and larger wagons rather than ordinary passenger sedans. That gives it a somewhat rugged service identity within the year’s overall tire landscape. Because these vehicles often see restoration changes or updated wheels, E78-15 should be confirmed against the exact wheel diameter and body clearance, especially on SUVs and vans that may no longer be stock.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

165R13 is a radial 80-series metric size used on several 1978 compact and small mid-size imports, including the Fiat 124, Fiat 131, Nissan 510, Nissan PL610, Plymouth Arrow, Renault Renault, and Toyota Corolla. This is one of the classic small-car radial formats of the era. Product choices include blackwall options from Michelin and Dunlop, with listed rim-width compatibility around 4.50 to 6.00 inches on several tires. For many 1978 import owners, 165R13 offers a straightforward route to maintaining the car’s original-size character without moving into lower-profile alternatives.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

145R13 is a small radial size used on the 1978 Fiat 128, Fiat X-1/9, MG Midget, and Renault Renault. It is one of the narrowest 1978 metric fitments and is closely associated with lightweight European small cars and sports cars. Product coverage includes blackwall radial choices from Michelin and Firestone, with one listed Firestone F560 carrying a maximum load capacity of 825 pounds at 44 psi. Because these cars are light and often sensitive to steering feel, maintaining the correct narrow-profile fitment can be especially important.

160R13 is a radial size used only on the 1978 Fiat 131. As a single-model fitment, it stands apart from more widely shared compact import sizes like 155R13 or 165R13. That makes precise identification particularly important for Fiat owners, since substitutions based only on approximate width can affect appearance and road feel. This size reflects the varied metric sizing practices still seen on imported cars in the late 1970s, when not every model fit neatly into the same handful of common replacement sizes.

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

G78-14 is a bias-ply size used on the 1978 Ford 500/Squire. Available products include dual-white-stripe, narrow whitewall, and wide whitewall designs from BFGoodrich and Coker Classic, all for 14-inch rims with listed widths of 5.00 to 7.00 inches. Maximum load capacity is shown at 1620 pounds at 32 psi on several options. Since this size is tied here to a large Ford passenger-car application, sidewall style can play a major role in whether the finished look reads formal, sporty, or more understated.

195R14 is a radial size used on the 1978 Ford Courier and Nissan 720 Pickup. In period terms, this is a light-truck and compact-pickup radial fitment rather than a standard domestic passenger-car size. Because these trucks are often modified with different wheels, especially surviving imported pickups, the key is to confirm wheel width and overall clearance before ordering. This size also illustrates how 1978 fitment crosses categories, with imported light trucks moving toward metric radial sizing while many domestic trucks still relied on traditional bias-ply formats.

6.00-14 is a bias-ply numeric size used on the 1978 Ford Courier, Mazda B1600 & 1800, and Toyota Hi-Lux. This traditional small-truck sizing format predates the widespread adoption of metric light-truck radials and remains important for period-correct restoration of compact pickups. Because these trucks were often used hard and later altered, owners should confirm that the current wheels still match the original intended diameter and width. The size is best understood as a vintage compact-truck fitment rather than a general-purpose 14-inch replacement.

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

E70-14 is a bias-ply performance-style size used on the 1978 Ford Courier. Product choices include Firestone Wide Oval and Goodyear Custom Wide Tread tires in pin-white-stripe, redline, and raised white letter configurations. Listed rim-width recommendations typically fall around 6.0 to 7.0 inches, with several products carrying maximum loads near 1400 pounds at 32 psi. For a compact pickup, that gives E70-14 a notably sporty presentation compared with ordinary utility sizes. It is a good fitment to research carefully if the truck has custom wheels or period-style appearance upgrades.

BR78-14 is a radial alpha-numeric size used on the 1978 Ford Fairmont and Mercury Zephyr. This size sits in the late-1970s transition zone where domestic compacts and intermediate cars could appear with either bias-ply or radial fitments depending on trim and equipment. Since Fairmont and Zephyr are closely related platforms, BR78-14 offers a targeted fitment path, but it still should be confirmed against the actual wheel setup. Owners aiming for a period domestic radial look may find this size especially appropriate for stock-style restoration goals.

CR78-14 is a radial size used on the 1978 Ford Fairmont and Mercury Zephyr. Like BR78-14 and DR78-14, it belongs to the domestic alpha-numeric radial family that was common during the era’s transition away from all-bias-ply fitment. Its appearance on these related compact/intermediate Ford products suggests trim and equipment variation rather than a universal platform size. That makes exact tire-size confirmation important, especially on cars that may have changed wheels over time or now wear different ride-height and suspension components.

Rim Diameter: 12 in  ·  Sidewalls: Blackwall

145R12 is a radial size used on the 1978 Ford Fiesta. Product coverage includes a Michelin MX blackwall radial with a listed 12-inch rim diameter, 4.5-inch rim width, and 72S specification. This is one of the smallest tire sizes used anywhere in the 1978 model year and is closely tied to compact imported or import-style hatchback packaging. Because 12-inch fitments are far less common than 13- and 14-inch sizes, Fiesta owners should verify wheel size first and avoid assuming interchange with nearby small-car dimensions.

155R12 is a radial size used on the 1978 Ford Fiesta and Honda Civic. This small 80-series metric radial reflects the compact-car engineering priorities of the period, where low weight and modest wheel diameters were common. Product coverage is not broad here, but the size itself remains important because it is more specialized than the many 13-inch import fitments seen in 1978. Owners should verify the exact wheel diameter before shopping, since a surviving compact may have been updated to a different wheel and tire package over time.

H70-14 is a bias-ply size used on the 1978 Ford GT. As a sporty domestic performance fitment, it belongs to the same visual world as other alpha-numeric and 70-series tires that emphasized stance and sidewall styling. While product coverage is not detailed here for this size, H70-14 should be approached as a specialized fitment rather than a generic 14-inch tire. For a 1978 Ford GT, wheel width and the owner’s desired period look will strongly influence whether a replacement tire feels visually right on the car.

Rim Diameter: 13 in  ·  Sidewalls: Narrow Whitewall

195/70R13 is a radial size used on the 1978 Ford Mustang and Mazda RX-4. Product coverage includes a BFGoodrich Silvertown Radial with a 7/16-inch whitewall, listed for 13-inch rims and 5.00- to 6.50-inch rim widths, with a maximum load capacity of 1246 pounds at 35 psi. This is a relatively uncommon late-1970s sporty compact size, larger than many economy-car 13-inch radials but still clearly within the small-car performance category. It works best when matched carefully to the original wheel width and intended visual character.

GR60-15 is a radial size used only on the 1978 Ford Van E-100 Econoline Van. Compared with the many 70-series and alpha-numeric van fitments from the same year, this lower-profile size stands out as more specialized. That makes it especially important to verify whether the van still carries its original wheel and suspension arrangement. On a vehicle class that is often customized, tire size alone is not enough. Owners should confirm wheel diameter, wheel width, and body clearance before assuming any current tire setup is stock.

9.50-19.5 is a bias-ply size used only on the 1978 GMC C/K Pickup. This is one of the most specialized heavy-duty fitments listed for the year, and the 19.5-inch wheel diameter immediately places it outside ordinary pickup-tire replacement territory. Because medium-duty wheel and tire standards differ substantially from passenger and light-truck applications, careful confirmation is essential. For surviving trucks, especially those used in commercial service or later modified, the exact wheel dimensions and intended load role should be checked before any replacement decision is made.

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

560-13 is a bias-ply compact size used on the 1978 Honda Accord, Mazda RX-3, Triumph Spitfire, and Volkswagen Base. Product options include narrow and wide whitewall versions from BFGoodrich and Firestone, with listed rim-width ranges around 3.50 to 4.50 inches and maximum load capacities of 850 pounds at 30 psi. This is a distinctly vintage small-car fitment that can dramatically influence the visual character of lightweight imports and sports cars. It is especially useful for owners seeking a traditional bias-ply appearance on period 13-inch wheels.

6.00-12 is a bias-ply size used on the 1978 Honda Civic. This is a very small traditional numeric fitment, reflecting the compact packaging of entry-level economy cars before larger wheels became the norm. Because 12-inch tires are relatively specialized today, exact wheel confirmation matters even more than usual. A Civic that has spent decades on the road may no longer wear its original wheel set, so 6.00-12 should be selected only after checking the actual diameter and current configuration rather than relying on year identification alone.

6.15-13 is a bias-ply compact-car size used on the 1978 Honda Civic, Mazda GLC, Nissan 210, Nissan F10, Subaru DL, Subaru GL, and Toyota Corolla. This traditional numeric sizing remained in use on many small imported cars even as equivalent-looking metric radial formats were becoming more common. Because several of these same models also appear with radial sizes, 6.15-13 should be treated as a specific period fitment rather than an interchangeable fallback. It is especially relevant for owners preserving the original feel and visual proportions of a late-1970s economy car.

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

225/75R15 is a radial size used on the 1978 International Scout II. Product choices include wide and narrow whitewall designs from BFGoodrich, Coker Classic, and American Classic, with listed rim-width recommendations generally spanning 6.00 to 8.00 inches. Stated load capacities range from 1874 pounds at 35 psi to 2094 pounds at 32 psi depending on the product. For a Scout II, this size offers a useful mix of road-going radial construction and period-looking whitewall options, but wheel width and actual vehicle use should still guide the final choice.

ER70-15 is a radial size used on the 1978 Jaguar XJ12C, Jaguar XJ12L, Jaguar XJ6, and Jaguar XJS. This fitment sits firmly in the luxury-performance touring category and is more specialized than common domestic full-size radial sizes. It is important not to confuse it with similar-looking alpha-numeric domestic formats that may differ in dimensions and intended application. For Jaguar owners, the priority should be preserving the correct overall balance of wheel fit, body clearance, and refined road manners rather than selecting by 15-inch diameter alone.

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

205/70R15 is a radial size used on the 1978 Jaguar XJ6, Jaguar XJS, and Maserati Merak. Product choices include narrow whitewall and blackwall designs from Maxxis, Michelin, Avon, and American Classic. Listed rim-width ranges run from about 5.00 to 7.50 inches depending on the tire, and stated load capacity reaches 1499 pounds at 35 psi on several options. This is a versatile period metric radial that can support either a more understated European blackwall look or a whitewall presentation where appropriate to the vehicle’s styling and owner preference.

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

600-16 is a bias-ply size used on the 1978 Jeep CJ6. Product coverage is extensive, including blackwall and wide whitewall options from BFGoodrich, Coker Classic, Avon, and Firestone, with listed rim widths around 4.00 to 4.50 inches and stated maximum load capacities of roughly 1400 to 1433 pounds depending on the tire. Although 600-16 is often associated with vintage utility vehicles, it can support very different restoration goals through sidewall choice alone. On a CJ6, confirming wheel width and intended use remains the practical first step.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

175/70R14 is a radial size used on the 1978 Lancia Beta and Mercedes-Benz 280. Current product coverage centers on a Travelstar narrow whitewall radial, which gives this otherwise European-oriented fitment a slightly different visual option than the all-blackwall choices common in many import sizes. Because it appears on two distinct but relatively refined passenger-car applications, 175/70R14 should be selected with attention to the car’s overall look and wheel fit. It is a more specialized mid-size import radial than the broader 185/70R14 and 205/70R14 categories.

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

195/60R15 is a radial size used on the 1978 Lotus Esprit. Available products include blackwall, wide whitewall, redline, and raised white letter options from BFGoodrich and Michelin. Listed rim-width ranges generally span 5.50 to 7.00 inches, and one BFGoodrich product lists a maximum load capacity of 1190 pounds at 35 psi. This is a lower-profile sports-car fitment compared with many mainstream 1978 tire sizes, so wheel width and vehicle stance are especially important. It suits owners who need a true period sports-car size rather than a generic 15-inch radial.

205/60R14 is a radial size used on the 1978 Lotus Esprit. In the context of 1978 fitment, it is clearly a specialized sports-car size with a lower profile than the more common 70-series domestic and import applications. That means selection should focus first on preserving the Esprit’s intended wheel and body relationship rather than simply finding any 14-inch radial. Because sports cars are especially sensitive to section width and sidewall height, confirming the exact wheel setup is critical before replacement.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, RWL

235/60R15 is a radial size used on the 1978 Lotus Esprit. Product options include blackwall and raised white letter tires from M&H Racemaster, Cooper, and BFGoodrich, with listed rim-width compatibility from about 6.5 to 8.5 inches and maximum load capacities around 1642 pounds at 35 psi on several products. This size has a distinctly performance-oriented profile and should be treated accordingly. On an Esprit, the choice among blackwall, RWL, and specialty-use products can significantly change the car’s period look and intended driving focus.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

165R14 is a radial size used on the 1978 MG MGB and Porsche 924. Product choices from Pirelli, Michelin, and Vredestein are all blackwall radials, with listed rim-width compatibility generally covering about 4.0 to 6.0 inches depending on the tire. This is a classic European 80-series metric fitment that suits a clean, understated period appearance. Because it appears on both a British sports car and a German sports coupe, 165R14 is best selected with attention to wheel width and the owner’s preferred balance of touring manners versus vintage sporting character.

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

215/70R15 is a radial size used on the 1978 Maserati Bora and Maserati Khamsin. Product coverage is broad, including blackwall, wide whitewall, and raised white letter options from Cooper, BFGoodrich, Dunlop, and Avon. Listed rim-width compatibility generally spans 5.5 to 7.5 inches, and stated load capacities range from 1620 to 1653 pounds depending on the tire. While the size itself is adaptable, these Maserati applications are highly style- and setup-sensitive, so owners should confirm the exact wheel dimensions and choose a sidewall treatment that suits the car’s design language.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

195/70R15 is a radial size used on the 1978 Maserati Merak. Product coverage here is centered on the Michelin XWX blackwall radial, reinforcing the size’s classic European sports-car identity. Because this is a single-application fitment within the year, it deserves careful attention to the actual wheel specification and tire profile rather than broad cross-shopping with more common domestic 15-inch sizes. For a Merak owner, 195/70R15 is primarily about preserving the correct period proportions and road behavior of the car.

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

735-14 is a bias-ply size used on the 1978 Mazda Truck Rotary Truck. Product choices include BFGoodrich blackwall and narrow whitewall versions, both listed for 14-inch rims with 5.00- to 5.50-inch rim widths and a maximum load capacity of 1360 pounds at 32 psi. This is a relatively uncommon light-truck fitment for the year, and it offers a good example of how compact pickups could still rely on traditional numeric bias-ply sizing. Sidewall choice allows either a plain utility look or a more restoration-oriented presentation.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

175R14 is a radial size used on the 1978 Mercedes-Benz 230, Mercedes-Benz 240, Mercedes-Benz 300, Peugeot 504, Peugeot 604, Toyota Celica, Toyota Corona, and Volvo DL. This 80-series metric fitment spans European sedans and coupes as well as a Japanese passenger-car application, making it one of the more versatile import-oriented sizes of the year. Product choices from Michelin and Vredestein are blackwall radials, with listed rim-width ranges around 4.5 to 6.0 inches on several tires. It suits owners wanting a clean, authentic late-1970s import look.

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

185R14 is one of the most broadly used 14-inch import-oriented radial sizes for 1978, appearing on Mercedes-Benz, Peugeot, Nissan, Toyota, Volkswagen, and Volvo applications. It serves passenger cars, compact pickups, and vans, including the Nissan 720 Pickup, Toyota Pickup, Volkswagen Campmobile, Volkswagen Kombi, Volkswagen Van Delivery Van, Volvo 265, and Volvo DL. Product choices include blackwall and narrow whitewall radials from Michelin, Phoenix, and Vredestein. With listed rim-width compatibility generally between 4.0 and 6.5 inches, 185R14 is a versatile but still application-sensitive size.

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

215/70R14 is a radial size used on the 1978 Mercedes-Benz 6.9. Product choices include blackwall, pin-white-stripe, narrow whitewall, and raised white letter designs from Cooper, Michelin, BFGoodrich, and Maxxis, with listed rim-width ranges around 5.5 to 7.5 inches and maximum load capacities near 1554 pounds at 35 psi on several products. Although the sidewall style range is broad, this remains a specialized high-end fitment. On a 1978 Mercedes-Benz 6.9, wheel correctness and the desired period character should drive the final product choice.

6.45-13 is a bias-ply compact-car size used on the 1978 Nissan 510 and Nissan PL610. This is a traditional numeric fitment from the era when some imports were still delivered with bias-ply tires even as radial replacements became increasingly common. Because both models also sit within a market segment that often gets updated wheels and later tire conversions, 6.45-13 should be chosen only after verifying the actual wheel diameter and restoration goal. It is most appropriate when preserving the original-style proportions of these smaller Nissan cars.

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

700-14 is a bias-ply size used on the 1978 Nissan 720 Pickup and Toyota Pickup. Product choices include BFGoodrich blackwall and narrow whitewall versions, each listed for 14-inch rims with 5.00- to 5.50-inch widths and maximum load capacities of 1360 pounds at 32 psi. This traditional small-pickup fitment is well suited to owners keeping these trucks close to their late-1970s working or restoration appearance. Because many imported pickups have since been customized, the practical first step is confirming wheel dimensions before selecting a 700-14 replacement.

165/70R13 is a radial size used only on the 1978 Nissan F10. It is a relatively specific compact-car fitment and differs from the more common 155R13 and 175/70R13 sizes used across many other 1978 imports. That narrower application means F10 owners should focus on exact size confirmation rather than approximate interchange. As with many late-1970s small-car tires, preserving the intended overall diameter and section width can help maintain the car’s original stance, steering response, and speedometer relationship.

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

600-13 is a bias-ply size used on the 1978 Plymouth Arrow and Renault Renault. Product choices include BFGoodrich narrow and wide whitewall versions, both listed for 13-inch rims and 4.00- to 4.50-inch rim widths, with a maximum load capacity of 1010 pounds at 32 psi. This is a good period small-car fitment for owners who want traditional bias-ply construction and visible sidewall styling. Because it appears on only two relatively compact imported models, 600-13 is best treated as a specific restoration-oriented size rather than a general 13-inch substitute.

215R15 is a radial size used on the 1978 Plymouth Fury. As an 80-series style metric radial, it fits within the larger full-size passenger-car category rather than the sportier 70-series performance segment. Its single-model application here makes precise confirmation important, especially because the Fury also appears alongside nearby domestic alpha-numeric and bias-ply sizes in the broader 1978 market. This size is best chosen with attention to the exact wheel setup and the owner’s preference for either a clean touring look or a more formal late-1970s presentation.

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

185/70R15 is a radial size used on the 1978 Porsche 911. Product options from Michelin, Dunlop, Avon, and BFGoodrich include blackwall and wide whitewall choices, with listed rim-width compatibility generally between 4.5 and 6.5 inches and load capacities around 1257 to 1279 pounds on some products. For a 911, this is clearly a sports-car fitment rather than a generic 15-inch radial. The right choice depends not only on the size, but also on wheel width, desired period appearance, and whether the owner prefers touring-oriented or sport-focused tire character.

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

215/60R15 is a radial size used on the 1978 Porsche 911 and Porsche 928. Product choices include wide whitewall, redline, raised white letter, and blackwall designs from American Classic, BFGoodrich, and Dunlop. Listed rim-width compatibility generally runs from 5.50 to 7.50 inches, with stated load capacities from about 1411 to 1477 pounds depending on the tire. This lower-profile size gives a distinctly sport-oriented stance, so it is especially important to confirm wheel width and visual goals before selection, particularly since the 911 and 928 have different design character.

225/50R15 is a radial size used on the 1978 Porsche 928. This is a lower-profile performance fitment that stands apart from the taller 70-series tires used on many other 1978 vehicles. Product choices include blackwall and raised white letter offerings from BFGoodrich and Michelin, with listed rim-width compatibility from 6.0 to 8.0 inches. Because the 928 is especially sensitive to tire proportion and wheel match, 225/50R15 should be selected carefully with the exact wheel dimensions in mind. It is not a casual interchange size despite sharing a familiar 15-inch diameter.

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

205/55R16 is a radial size used on the 1978 Porsche 930. Product coverage includes blackwall performance tires from BFGoodrich and Michelin, with listed rim-width compatibility generally between 5.5 and 7.5 inches and load capacities up to 1477 pounds on some options. Within the 1978 model year, this is one of the more modern-feeling fitments, combining a low profile with a 16-inch wheel diameter that was still uncommon at the time. It should be chosen with exact wheel and chassis setup in mind, especially on a performance-focused car like the 930.

Rim Diameter: 16 in  ·  Sidewalls: Blackwall

225/50R16 is a radial size used on the 1978 Porsche 930. Available blackwall performance products from BFGoodrich and Michelin list 16-inch rim diameter compatibility and rim-width ranges from 6.0 to 8.0 inches. As with 205/55R16, this size sits well outside the mainstream late-1970s passenger-car tire landscape and belongs to a specialized high-performance application. On a Porsche 930, tire size, wheel width, and overall tire profile are tightly connected, so this fitment deserves careful confirmation before replacement or comparison shopping.

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

235/70R15 is a radial size used on the 1978 Rolls Royce Camargue and Rolls Royce Corniche. Product choices include blackwall, redline, and raised white letter offerings from Cooper, Avon, BFGoodrich, and Michelin, with listed rim-width compatibility generally between 6.0 and 8.5 inches and load capacities up to 1896 pounds at 35 psi on some products. Although the sidewall options are varied, this remains a luxury fitment where overall proportion and refined road manners matter. It should be chosen with attention to wheel width and the car’s intended visual presentation.

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

165R15 is a radial size used on the 1978 Saab 99 and Volkswagen Beetle. Product coverage is broad, with blackwall, narrow whitewall, and wide whitewall choices from Coker Classic, American Classic, Firestone, and BFGoodrich. Listed rim-width compatibility generally spans 4.50 to 6.00 inches, with maximum load capacities around 1168 to 1170 pounds on several tires. This is a classic 80-series metric fitment that can suit either a clean European blackwall look or a more stylized restoration approach, depending on the vehicle and sidewall treatment selected.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

175/70R15 is a radial size used on the 1978 Saab 99. Available products include blackwall radials from Avon and Vredestein, both listed for 15-inch rims with 4.5- to 6.0-inch wheel compatibility. One listed Vredestein carries a maximum load capacity of 1168 pounds at 51 psi. Compared with the taller 165R15 fitment also seen in this year, 175/70R15 gives the Saab 99 a lower-profile radial option that should be matched carefully to the actual wheel and the owner’s preferred balance of period look and road behavior.

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

750-14 is a bias-ply size used on the 1978 Toyota Pickup. Product coverage is broad and style-driven, with blackwall, narrow whitewall, wide whitewall, and redline choices from BFGoodrich, US Royal, and Coker Classic. Listed rim-width compatibility generally falls between 5.00 and 5.50 inches, with maximum load capacities around 1500 to 1580 pounds at 32 psi depending on the tire. For a compact pickup, this gives 750-14 unusual visual flexibility. It can support a stock utility look, a cleaner restored appearance, or a mild period custom presentation.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

185R13 is a radial size used on the 1978 Triumph TR7. Product coverage includes a Michelin XAS-FF blackwall radial, reinforcing the size’s imported sports-car character. This 80-series metric fitment is taller in profile than the lower 70-series radial sizes also seen on some sporty 1978 cars, so it should be selected with close attention to the actual wheel and intended handling balance. On a TR7, preserving the correct relationship between tire height, wheel width, and body stance is often more important than adding visual sidewall features.

155D15 is a bias-ply size used on the 1978 Volkswagen Beetle. The D construction code marks it as a bias tire, which is a meaningful distinction on a model that also appears with 165R15 radial fitment. For Beetle owners, the choice between these sizes is not simply about width; it also affects sidewall profile, driving feel, and restoration direction. Because many Volkswagens have been updated over time, 155D15 should be confirmed against the actual wheel and the owner’s goals before selecting a replacement.

155D13 is a bias-ply size used on the 1978 Volkswagen Rabbit. This is a small bias-construction fitment that contrasts with the Rabbit’s available 155R13 and 155/80R13 radial sizes, making careful identification especially important. For a surviving Rabbit, that means checking the actual tires and wheels currently on the car instead of assuming one size fits all examples. As a bias-ply option, 155D13 is most relevant when preserving a period-specific setup rather than moving toward later radial-style replacement choices.
