1975 Vehicle Tire Fitment Guide

C78-14 is a bias-ply size associated here with the 1975 American Motors Hornet. As an alphanumeric bias-ply designation, it belongs to the domestic sizing systems common before metric radials became dominant across the market. No product listing is shown for this size in the current selection, so it is especially important to verify the car’s actual tire size and wheel setup before moving toward a substitute or alternate product search. On cars from this period, trim level, tire package, and prior wheel changes can all affect what is currently mounted.

ER78-14 is an alphanumeric radial size used on several 1975 domestic intermediates and compacts, including the 1975 American Motors Matador, 1975 Dodge Dart, 1975 Ford Granada, 1975 Mercury Monarch, and 1975 Plymouth Duster. This size reflects the growing presence of radials in mainstream American cars during the mid-1970s. Product listings are not shown here for ER78-14, so shoppers should focus on confirming the exact application before comparing alternatives. Because these cars could also appear with nearby bias-ply or other alphanumeric radial sizes, ER78-14 should be matched carefully to the vehicle’s wheel and intended stance.

FR78-14 is a widely shared radial size across 1975 domestic cars, appearing on models such as the 1975 Buick Apollo, 1975 Buick Skylark, 1975 Chevrolet Camaro, 1975 Chevrolet Nova, 1975 Ford Granada, 1975 Oldsmobile Omega, and 1975 Pontiac Ventura. It sits in the popular 14-inch alphanumeric radial category that served many compact and mid-size American platforms. No specific products are listed here for FR78-14, but its broad use suggests it was a common fitment for buyers wanting radial ride characteristics in that segment. Because several of these cars also carried neighboring bias-ply sizes, exact fitment should still be confirmed.

Rim Diameter: 14 in  ·  Sidewalls: Wide Whitewall

F78-14 is a bias-ply 14-inch size found on a mix of 1975 domestic cars and wagons, including the 1975 American Motors Matador, 1975 Chevrolet Camaro, 1975 Dodge Charger, 1975 Dodge Coronet, 1975 Plymouth Fury, and certain Dodge van-based passenger applications. It represents a familiar alphanumeric bias-ply fitment from the period. The current product selection shows a Coker Classic Bias Ply with a 2.375-inch whitewall, a 14-inch rim diameter, and a listed 5.00 to 7.00-inch rim-width range. That makes this size especially relevant for owners pursuing a strong period-style whitewall presentation on mid-1970s American vehicles.

Rim Diameter: 14 in  ·  Sidewalls: Wide Whitewall

H78-14 is a larger bias-ply 14-inch size used on several 1975 domestic intermediate and full-size models, including the 1975 American Motors Matador, 1975 Chevrolet Chevelle, 1975 Dodge Charger, 1975 Dodge Coronet, 1975 Ford 500 & Squire, and 1975 Plymouth Fury. Compared with smaller F- and G-series sizes, it supports heavier, broader vehicles and a fuller sidewall look typical of the era. The listed product is a Coker Classic Bias Ply with a 2.50-inch whitewall, built for 14-inch wheels and a 5.50 to 8.00-inch rim-width range, making it a distinctly restoration-oriented appearance choice.

HR78-14 is an alphanumeric radial size that appears on 1975 domestic intermediates and personal-luxury cars, including the 1975 American Motors Matador, 1975 Dodge Charger, 1975 Ford 500 & Squire, 1975 Ford GT, 1975 Ford Gran Torino, 1975 Mercury Cougar, and 1975 Mercury Montego. This size reflects the mid-1970s shift toward radials on larger American passenger cars. Product listings are not shown here, so buyers should use the vehicle-specific fitment path to confirm whether HR78-14 applies to their exact model and package. It should not be assumed interchangeable with nearby H78-14 bias-ply sizing without additional fitment review.

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

GR70-15 is one of the more performance-oriented 1975 sizes, used on vehicles such as the 1975 Aston Martin AM, 1975 Chevrolet Corvette, 1975 Chevrolet Monte Carlo, 1975 Pontiac Firebird, 1975 Pontiac Grand Am, and 1975 Pontiac Grand Prix. The 70-series profile points to a lower, wider look than taller alphanumeric touring sizes. Available products center on Goodyear bias-look radial designs with RWL and pin-white-stripe sidewalls, including GM Custom Tread and Steelgard series, with listed 15-inch rim fitment and wheel widths generally in the 7.0 to 8.0-inch range. This size is especially relevant where appearance and period performance character matter.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

155R13 is a compact metric radial size used across many small 1975 imports, including the 1975 Audi Fox, 1975 Austin Marina, 1975 Fiat 128, 1975 Mazda 808, 1975 Nissan F10, 1975 Subaru DL, 1975 Triumph Spitfire, 1975 Volkswagen Rabbit, and 1975 Volkswagen Scirocco. It represents the narrow, tall-profile radial format common on economical European and Japanese cars of the period. Available products are blackwall radials from Michelin and Dunlop, with listed rim-width compatibility that suits small 13-inch wheels. For these applications, staying with the correct narrow-section size is often important for steering feel, fender clearance, and period proportions.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

175/70R13 is a sporty small-car radial size used on the 1975 Audi Fox, 1975 Volkswagen Dasher, and 1975 Volkswagen Scirocco. Compared with 155R13, it is a wider and lower-profile fitment, better aligned with trim levels or configurations seeking a more planted stance and quicker response. The listed product is an Avon CR6ZZ blackwall radial with a 13-inch rim diameter and a 4.5 to 6.0-inch recommended rim-width range. Because this size is not widely shared across the full 1975 field, it is worth confirming whether the car still wears its intended wheel size before ordering.

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

560-13 is a bias-ply size seen on smaller 1975 imports such as the 1975 Austin Marina, 1975 Mazda RX-3, 1975 Renault, 1975 Triumph Spitfire, and 1975 Volkswagen Dasher. It reflects an older small-car sizing convention that overlaps with radial-era vehicles still offered with traditional bias-ply fitments. Current products include BFGoodrich and Firestone classic bias-ply tires in narrow and wide whitewall styles, all for 13-inch wheels, with listed rim-width ranges generally around 3.50 to 4.50 inches depending on product. That gives restorers a clear visual choice when preserving a period-correct-looking small-car presentation.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

165R13 is a common 1975 metric radial size used on a broad group of compact European and Japanese cars, including the 1975 BMW 2002 & 2002A, 1975 BMW 2002 Tii, 1975 Fiat 124, 1975 Fiat 131, 1975 Nissan PL610, 1975 Opel 1900, 1975 Toyota Celica, and 1975 Toyota Corolla. This tall-profile 13-inch radial was a mainstay for small sporting sedans and coupes. Product choices include blackwall radials from Michelin and Dunlop, with Michelin XAS and XAS-FF offerings and listed rim-width ranges of 4.50 to 6.00 inches. It is a strong fitment category for owners seeking classic European-style road manners.

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

600-13 is a bias-ply size associated with 1975 compact imports including the 1975 BMW 2002 & 2002A, 1975 Opel 1900, 1975 Opel Manta, and 1975 Renault. It serves as a traditional counterpart to the metric radial sizes often found on similar vehicles from the same period. Available products are BFGoodrich classic bias-ply tires in wide whitewall and narrow whitewall treatments, both built for 13-inch wheels with listed 4.00 to 4.50-inch rim-width compatibility. For shoppers working on restoration-focused cars, this size offers a distinctly vintage sidewall look compared with blackwall radial alternatives.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

175R14 is a classic metric radial size used across several 1975 European sedans and coupes, including the 1975 BMW 3.0CS & 3.0CSA, 1975 Mercedes-Benz 230, 1975 Mercedes-Benz 240, 1975 Mercedes-Benz 300, 1975 Nissan 260Z, 1975 Peugeot 504, 1975 Toyota Corona, 1975 Toyota Mark II, and 1975 Volvo DL. It sits in the traditional 80-series-style radial category that balances comfort, period appearance, and everyday drivability. Available blackwall products come from Michelin and Vredestein, with some listed rim-width ranges of 4.5 to 6.0 inches. This is a premium classic radial fitment rather than a whitewall-heavy domestic style size.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

195/70R14 is a relatively modern-looking metric radial size for 1975, appearing on the 1975 BMW 3.0CS & 3.0CSA, 1975 BMW 3.0S & 3.0SA, 1975 BMW 530i & 530iA, and 1975 Nissan 280Z & 280A 2+2. It points to larger-displacement imported cars with a wider footprint and lower profile than earlier 175-series fitments. The listed product is a Dunlop Sport Classic blackwall radial with a 15-inch-era performance flavor adapted to a 14-inch application and a stated maximum load capacity of 1,356 pounds. For these vehicles, section width and overall stance are especially important to preserve proper appearance and clearance.

HR70-15 is an alphanumeric radial size used on more upscale and performance-leaning 1975 vehicles such as the 1975 Bentley T Series, 1975 Chevrolet Chevelle, 1975 Chevrolet Monte Carlo, 1975 Ford Gran Torino, and 1975 Oldsmobile Cutlass. The 70-series profile gives it a lower stance than taller 78-series fitments, making it an important visual and handling distinction within mid-1970s American and luxury applications. Product details are not listed here for this size, so buyers should confirm exact fitment carefully. On vehicles offered with multiple optional tire packages, HR70-15 should not be treated as interchangeable with HR78-15.

FR78-15 is an alphanumeric radial size used on selected 1975 intermediate and sporty domestic cars, including the 1975 Buick Century, 1975 Chevrolet Chevelle, 1975 Oldsmobile Cutlass, 1975 Pontiac Firebird, and 1975 Pontiac LeMans. It occupies a smaller 15-inch radial category than GR78-15 or HR78-15, making it relevant to buyers comparing stance and wheel-package differences within the same body family. Product listings are not shown here for FR78-15, so its main value on this page is fitment identification. When researching these cars, it is wise to confirm whether the vehicle has base, sport, or optional wheel equipment.

HR78-15 is one of the broadest 1975 fitment sizes, used across domestic sedans, wagons, coupes, vans, utility vehicles, and some Jeep and International applications. It appears on models ranging from the 1975 Buick Century and 1975 Chrysler Newport to the 1975 Ford LTD, 1975 Jeep CJ5 & CJ7, and 1975 Plymouth Gran Fury. This wide use makes it a central size for 1975 American tire research, but exact fitment still varies by model and package. Product specifications are not shown here, so buyers should use the size as a fitment checkpoint, then verify wheel type, intended use, and vehicle configuration.

JR78-15 is a larger alphanumeric radial size associated mainly with full-size and premium 1975 American cars and vans, including the 1975 Buick Electra, 1975 Buick Riviera, 1975 Chrysler New Yorker, 1975 Ford LTD, 1975 Mercury Marquis, 1975 Oldsmobile 98 Series, and 1975 Pontiac Catalina. Its application pattern points to heavier passenger vehicles where a substantial 15-inch touring tire was appropriate. No product listing is shown here for JR78-15, so the size serves primarily as a guide to the fitment family. Because nearby HR78-15 and LR78-15 sizes were also common, exact vehicle matching matters.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall

LR78-15 is a large radial fitment used on many 1975 full-size American cars, wagons, and some trucks, including the 1975 Buick Estate Wagon, 1975 Cadillac Calais & DeVille, 1975 Cadillac Eldorado, 1975 Chevrolet C/K Pickup, 1975 Chevrolet Suburban, 1975 Chrysler Town & Country, 1975 Ford Thunderbird, and 1975 Pontiac Grand Safari. The listed product is a Firestone Steel Belted 721 bias-look radial with a narrow whitewall, 15-inch rim diameter, and a 5.50 to 8.00-inch rim-width range. Its load capacity and styling make it especially relevant for larger, heavier vehicles where both profile and presentation matter.

GR78-15 is a popular 1975 domestic radial size found on vehicles such as the 1975 Buick Regal, 1975 Cadillac Seville, 1975 Chevrolet Chevelle, 1975 Chevrolet El Camino, 1975 Chrysler Cordoba, 1975 Dodge Charger, 1975 Oldsmobile Cutlass, 1975 Pontiac Firebird, and 1975 Pontiac Grand Prix. It sits in the middle of the 15-inch alphanumeric radial range, often associated with sporty or personal-luxury trims. Product details are not listed here for this size, but it remains a key bridge between full-size 78-series touring fitments and lower-profile 70-series performance sizes. Careful vehicle and wheel verification remains important.

BR78-13 is a compact alphanumeric radial size used on several 1975 small domestic cars, including the 1975 Buick Skyhawk, 1975 Chevrolet Monza, 1975 Ford Mustang, 1975 Ford Pinto, 1975 Oldsmobile Starfire, and 1975 Pontiac Astre. It reflects the fuel-economy and compact-car direction of the period while still fitting within domestic alpha-numeric sizing practice. No product listing appears here for BR78-13, so buyers should focus on confirming whether their car uses this radial size or one of the neighboring A- or B-series alternatives. On small cars from this era, tire height can noticeably affect gearing feel and wheelwell appearance.

NR78-15 is a specialized radial size listed for the 1975 Cadillac Commercial Series. Its single-application nature suggests a fitment aimed at a heavier professional-car platform rather than a broadly shared passenger-car size. No current product details are shown here, so anyone researching this application should confirm not only year and model but also the exact coachbuilt or commercial configuration involved. Vehicles in this category often differ in weight, wheel equipment, and intended service compared with standard Cadillac passenger cars, making exact size matching far more important than broad year-only searching.

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

G78-15 is a very common 1975 bias-ply size used across full-size cars, pickups, vans, and sport-utility models, including the 1975 Checker Marathon & Taxi, 1975 Chevrolet Blazer, 1975 Chevrolet C/K Pickup, 1975 Dodge Ramcharger, 1975 Ford Bronco, 1975 Ford F-100, 1975 GMC Jimmy, and 1975 Plymouth Trailduster. The available product mix shows how broad this category is: whitewall passenger-car choices from Coker Classic and a blackwall STA Super Traxion truck-style option. With listed 15-inch fitment and load-oriented construction, this size can support very different appearance and use goals depending on the vehicle.

E78-15 is a smaller 15-inch bias-ply size used on selected 1975 utility vehicles and vans, including the 1975 Chevrolet Blazer, 1975 Dodge Ramcharger, 1975 Ford Bronco, 1975 GMC Jimmy, and certain van and wagon applications from Dodge, GMC, and Plymouth. It occupies an interesting middle ground between passenger-car and light-truck use in the mid-1970s. Current products include a whitewall Coker Classic Bias Ply as well as blackwall STA Traxion and STA Transport Highway tires. That variety makes this size relevant both for period-correct styling and for buyers prioritizing a more truck-oriented tread presentation.

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

H78-15 is one of the most widely used 1975 bias-ply sizes, appearing on a broad range of domestic trucks, vans, utility vehicles, and some wagons. Applications include the 1975 Chevrolet Blazer, 1975 Chevrolet C/K Pickup, 1975 Dodge Pickup, 1975 Ford F-100, 1975 Ford F-150, 1975 GMC Jimmy, 1975 International Travelall 150, 1975 Jeep Cherokee, and 1975 Toyota Land Cruiser. Available products include Coker Classic wide whitewalls and STA blackwall truck-style tires, with listed rim-width ranges generally around 5.50 to 7.00 inches. This size can serve either restoration appearance goals or more utilitarian visual preferences.

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

L78-15 is a larger 15-inch bias-ply size commonly used on 1975 pickups, large wagons, and utility vehicles, including the 1975 Chevrolet Blazer, 1975 Chevrolet C/K Pickup, 1975 Dodge Pickup, 1975 Ford Bronco, 1975 Ford F-150, 1975 GMC C/K Pickup, 1975 International Pickup 150, and 1975 Plymouth Trailduster. The product range includes blackwall, narrow whitewall, and multiple wide whitewall designs from Coker Classic and BFGoodrich, all with listed 15-inch fitment and 5.50 to 8.00-inch rim-width ranges. It is a versatile size for buyers balancing heavier-vehicle capacity needs with a distinctly period sidewall style.

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

700-15 is a numeric bias-ply size used heavily on 1975 trucks and utility vehicles, including the 1975 Chevrolet Blazer, 1975 Chevrolet C/K Pickup, 1975 Dodge Pickup, 1975 Ford Bronco, 1975 Ford F-100, 1975 GMC Jimmy, 1975 International Travelall 150, and 1975 Plymouth Trailduster. It is also seen on some van-based applications. Current products include Firestone and BFGoodrich classic bias-ply tires in blackwall and wide whitewall styles, plus an STA Traxion blackwall option. Listed rim-width recommendations center on 5.00 to 5.50-inch wheels, making wheel verification important when dealing with restored or modified 4x4s and trucks.

F78-15 is a bias-ply 15-inch size used on various 1975 vans, wagons, and utility models, including the 1975 Chevrolet Blazer, 1975 Chevrolet Van Sportvan, 1975 Chevrolet Van, 1975 Ford Van E-100 Econoline Van, 1975 GMC Jimmy, 1975 GMC Rally, 1975 Jeep CJ5 & CJ7, 1975 Jeep CJ6, and 1975 Plymouth Wagon. This size often fits lighter-duty 15-inch applications compared with H78-15 or L78-15. The current product listing is a Coker Classic Bias Ply with a wide whitewall and a stated 5.00 to 7.00-inch rim-width range. It is particularly useful where period sidewall appearance is part of the vehicle’s presentation.

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

700-16 is a heavier-duty numeric bias-ply size used on the 1975 Chevrolet C/K Pickup, 1975 Chevrolet Suburban, 1975 GMC C/K Pickup, and 1975 GMC Suburban. Moving from 15-inch passenger and utility sizes to 16-inch truck fitment usually signals a more work-oriented wheel and tire package. Available products include blackwall and wide whitewall choices from Lester, Avon, BFGoodrich, and Firestone, giving this size a broader visual range than many truck applications. Some products list load capacities up to the upper 1,800-pound range, so this size is important for owners matching truck appearance with appropriate wheel diameter and use expectations.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

875-16.5 is a 16.5-inch bias-ply truck size used across many 1975 heavy-duty pickups, vans, club wagons, and utility vehicles, including the 1975 Chevrolet C/K Pickup, 1975 Ford F-150, 1975 Ford F-250, 1975 Ford F-350, 1975 GMC Rally, 1975 International Pickup 200, and 1975 Jeep Truck J-20. This fitment belongs to the mid-1970s 16.5-inch truck-wheel era, which requires close attention because it is not interchangeable with 16-inch rims. Available blackwall products from STA include Traxion and Transport Highway versions, both focused on truck use rather than decorative sidewall styling.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

950-16.5 is a large bias-ply truck size used on select 1975 heavy-duty applications such as the 1975 Chevrolet C/K Pickup, 1975 Chevrolet Suburban, 1975 Dodge Pickup, 1975 Ford F-250, 1975 Ford F-350, 1975 Ford Van E-350 Econoline Van, 1975 GMC C/K Pickup, and 1975 Jeep Truck J-20. It is firmly in the heavy-service 16.5-inch category, so wheel diameter confirmation is essential before selection. Current blackwall products from STA include Traxion and Super Transport versions, both with listed 6.50 to 6.75-inch rim-width ranges and a stated maximum load capacity of 2,780 pounds at 60 psi.

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

750-16 is a numeric bias-ply truck size used on 1975 heavier pickups and utility vehicles, including the 1975 Chevrolet C/K Pickup, 1975 Chevrolet Suburban, 1975 Dodge Pickup, 1975 Ford F-250, 1975 Ford F-350, 1975 GMC C/K Pickup, 1975 GMC Suburban, and 1975 Jeep Truck J-20. It offers a 16-inch alternative to the era’s 16.5-inch truck sizes, which can matter greatly when confirming the wheel already on the vehicle. Available products include blackwall and wide whitewall versions from Firestone, Lester, and BFGoodrich, with listed rim-width ranges of 5.00 to 6.00 inches. That makes it useful in both work-truck and restoration-style contexts.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

800-16.5 is a bias-ply truck size used broadly across 1975 heavy-duty vans, pickups, wagons, and utility platforms, including the 1975 Chevrolet C/K Pickup, 1975 Dodge Pickup, 1975 Dodge Van Tradesman Van, 1975 Ford E-250 Club Wagon, 1975 Ford F-250, 1975 Ford F-350, 1975 GMC Vandura, 1975 International Travelall 200, and 1975 Jeep Truck J-20. Because 16.5-inch fitment is very specific, this size requires verification of the actual wheel diameter before ordering. Current products are blackwall STA Super Transport and STA Traxion tires, with listed rim-width coverage in the 6.00 to 6.50-inch range on the Super Transport offering.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

10-16.5 is a large bias-ply truck tire size associated here with the 1975 Chevrolet C/K Pickup and 1975 GMC C/K Pickup. It belongs to the heavier end of the 16.5-inch pickup-truck spectrum and should be approached as a dedicated wheel-and-tire package, not a casual substitute for 16-inch applications. The listed product is an STA Traxion blackwall tire with a stated 16.5-inch rim diameter, 8.25-inch rim width, and maximum load capacity of 2,680 pounds at 60 psi. For trucks that still retain this setup, wheel identification and clearance confirmation are especially important.

Rim Diameter: 15 in  ·  Sidewalls: RWL

E60-15 is a performance-style bias-ply size used here on the 1975 Chevrolet Camaro. The low-profile letter-series format was strongly associated with sporty mid-1970s American applications and delivers a noticeably different look from taller alphanumeric touring tires. The listed product is a Goodyear Polyglas GT with raised white letters, a 15-inch rim diameter, a 7-inch rim-width specification, and a stated maximum load capacity of 1,400 pounds at 32 psi. For Camaro owners, this size is as much about period stance and sidewall character as it is about basic fitment.

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

G78-14 is a common bias-ply 14-inch size used on 1975 domestic intermediates and full-size cars such as the 1975 Chevrolet Chevelle, 1975 Dodge Charger, 1975 Dodge Coronet, 1975 Ford 500 & Squire, and 1975 Plymouth Fury. Available products show a strong emphasis on traditional styling, with dual white stripes, narrow whitewalls, and multiple wide whitewall widths from BFGoodrich and Coker Classic. Listed rim-width ranges run from 5.00 to 7.00 inches. This size is especially useful for restorers trying to capture the fuller sidewall look that defines many American sedans and coupes of the era.

6.00-14 is a numeric bias-ply size used on several compact 1975 pickups, including the 1975 Chevrolet Luv Pickup, 1975 Ford Courier, 1975 Mazda B1600 & 1800, 1975 Nissan PL620, 1975 Nissan Pickup, and 1975 Toyota Hi-Lux, while also appearing with the 1975 Nissan Lil Hustler. This is a practical light-truck fitment rather than a passenger-car styling size. No product listing is shown here, so its main role on the page is helping identify the correct application family. For small imported trucks, staying close to the intended section width can help preserve steering effort and fender clearance.

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

E78-14 is a bias-ply 14-inch size used on 1975 compact and utility-oriented domestic vehicles, including the 1975 Chevrolet Nova, 1975 Dodge Dart, 1975 Dodge Sportsman Wagon, 1975 Dodge Van Tradesman Van, 1975 Oldsmobile Omega, and 1975 Plymouth Valiant. Product offerings span different use cases, from a Coker Classic wide whitewall to STA blackwall Traxion and Transport Highway designs. Listed rim-width ranges vary by product, generally covering the common 4.50 to 7.00-inch range for passenger or utility wheels. That mix makes E78-14 relevant both for appearance-driven restorations and more work-focused presentations.

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

650-16 is a numeric bias-ply size used on the 1975 Chevrolet Suburban and 1975 Ford F-100. It bridges traditional passenger-truck proportions with 16-inch wheel fitment and can be an important size when a surviving truck does not use the more common 15-inch setup. The available product range is broad, including blackwall and wide whitewall choices from BFGoodrich, Coker Classic, Firestone, and Garfield, with listed 4.50 to 5.00-inch rim-width compatibility on several products. That gives owners flexibility to pursue either a more utilitarian truck look or a more polished restoration presentation.

A70-13 is a performance-style bias-ply size listed here for the 1975 Chevrolet Vega. In 1970s domestic sizing, the A70 format points to a low-profile look relative to taller alphanumeric touring sizes, making it a distinct visual and handling category for small sporty cars. No product details are shown here for A70-13, so this size functions mainly as a fitment identifier for Vega owners researching period-correct proportions. Because small domestic cars often saw wheel changes over time, checking the actual wheel diameter and current tire markings remains a smart first step.

A78-13 is a small bias-ply 13-inch size used on the 1975 Chevrolet Vega, 1975 Dodge Colt, and 1975 Pontiac Astre. It belongs to the domestic alphanumeric bias-ply system and represents a more standard-profile alternative to sportier low-profile letter-series fitments. No specific products are listed here for A78-13, so shoppers should use the size primarily to identify which fitment family their car falls into. Since some of these compact models also appeared with radial options, keeping the exact size and construction aligned with the vehicle’s wheels and intended character is important.

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

J78-15 is a bias-ply 15-inch size associated with 1975 full-size van applications, including the 1975 Chevrolet Van Sportvan, 1975 Chevrolet Van, 1975 GMC Rally, and 1975 GMC Vandura. Compared with many passenger-car 15-inch sizes, this fitment leans toward larger van duty and a substantial sidewall. Available products are BFGoodrich classic bias-ply tires with either dual white stripes or a narrow whitewall, both listing 5.50 to 7.00-inch rim-width compatibility. For large vans, this size can be a strong match where buyers want a period visual treatment rather than a plain commercial blackwall look.

BR70-13 is a compact radial size used on the 1975 Dodge Colt, 1975 Ford Pinto, 1975 Mazda RX-4, and 1975 Oldsmobile Starfire. The 70-series profile marks it as a lower-profile radial option than taller 78-series or 80-series fitments, making it more appearance- and handling-oriented for smaller cars. Product listings are not shown here, so this size serves chiefly as a fitment identifier within the 1975 range. On compact cars from this period, moving away from the intended aspect ratio can significantly change stance, gearing feel, and wheel-arch fill.

D78-14 is a bias-ply 14-inch size used on the 1975 Dodge Dart, 1975 Plymouth Duster, and 1975 Plymouth Valiant. It belongs to the smaller side of the domestic alphanumeric bias-ply range and is typically associated with compact rear-wheel-drive American cars. No products are listed here for D78-14, so its main purpose is helping owners identify the correct fitment family for further research. Since those same model lines could also use nearby 695-14, E70-14, or ER78-14 depending on configuration, this size should be verified directly from the vehicle and wheel combination.

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

E70-14 is a sporty 14-inch bias-ply size used on the 1975 Dodge Dart and 1975 Plymouth Duster. Its 70-series profile gives it a lower, wider look than many standard 78-series tires of the same era, making it a meaningful style and stance choice on compact domestic performance trims. The product range is extensive, with Firestone and Goodyear offerings in pin-white-stripe, redline, and RWL sidewall treatments. Listed rim-width recommendations generally run from 6.0 to 7.0 inches. This size is especially relevant for period muscle and performance-inspired builds where sidewall detail matters.

9.50R16.5 is a radial light-truck size used on the 1975 Dodge Pickup and 1975 Ford Van E-350 Econoline Van. It stands apart from the many bias-ply truck sizes of the year by combining a radial construction with 16.5-inch wheel fitment. No product listing is shown here for this specific size, so buyers should focus first on confirming both wheel diameter and intended load use. Because 16.5-inch tires are a distinct category and some 1975 trucks also used similarly named bias-ply sizes, exact marking verification on the vehicle is essential before selection.

8.75R16.5 is a radial truck fitment used on the 1975 Dodge Pickup, 1975 Ford E-250 Club Wagon, and 1975 Ford Van E-250 Econoline Van. Its combination of radial construction and 16.5-inch diameter reflects the mixed truck-sizing landscape of 1975, when heavy-duty applications could span both bias-ply and radial choices. No product details are listed here, so this size is best used as a precise fitment checkpoint during research. Owners should verify the wheel diameter carefully, since 16.5-inch fitments require their own tire category and are not directly interchangeable with 16-inch truck tires.

8.00R16.5 is a radial truck size listed for the 1975 Dodge Pickup. As a single-application 16.5-inch radial fitment within this guide, it should be approached carefully and verified against the actual wheel and axle setup on the vehicle. No current product listing is shown here, which makes size confirmation even more important before moving on to substitute research. On heavy-duty trucks from this period, surviving vehicles may have seen wheel changes over the years, so the exact sidewall marking and wheel diameter should lead the selection process rather than assumptions based on model name alone.

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

700-14 is a numeric bias-ply size used on the 1975 Dodge Sportsman Wagon, 1975 Dodge Van Tradesman Van, and 1975 Toyota Pickup. This is a practical 14-inch fitment that crosses between domestic van use and compact truck duty rather than serving a broad passenger-car market. Available products are BFGoodrich classic bias-ply tires in blackwall and narrow whitewall styles, both with listed 5.00 to 5.50-inch rim-width ranges and a 14-inch diameter. That gives this size a straightforward period-correct option set for owners who want either a plain commercial-style look or a cleaner vintage sidewall accent.

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

205/70R14 is a wider metric radial size used on the 1975 Ferrari 308, 1975 Lotus Esprit, and 1975 Mercedes-Benz 450.

It sits in the classic grand-touring performance category and is supported by a diverse product range, including blackwall sport-oriented radials from Dunlop and Avon, RWL choices from Cooper, and a wide whitewall BFGoodrich Silvertown Radial. Listed rim-width ranges generally run from 5.5 to 7.5 inches. For these applications, the tire’s visual profile and speed-oriented character are both important, so exact sizing and wheel suitability should be confirmed rather than approximated.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

145R13 is a narrow metric radial size used on several small 1975 imports, including the 1975 Fiat 128, 1975 Fiat X-1/9, 1975 MG Midget, and 1975 Renault. It represents the slim, tall-profile radial format commonly associated with lightweight European economy and sports cars of the era. The listed products are blackwall radials from Michelin and Firestone, with Firestone showing a 4.00 to 5.00-inch rim-width range and a stated load capacity of 825 pounds at 44 psi. Because these vehicles are sensitive to tire width and rolling diameter, keeping the fitment narrow and proportionate is often important.

160R13 is a metric radial size listed specifically for the 1975 Fiat 131. As a single-application size within this year group, it should be treated as a precise fitment rather than a broad substitute category. No product information is shown here for 160R13, so the key research step is confirming whether the vehicle still uses the intended wheel and tire dimensions. Imported sedans of this period often depended on relatively narrow, tall-profile radials for their original steering and ride balance, so moving significantly away from the specified section width can alter both appearance and road manners.

Rim Diameter: 16.5 in  ·  Sidewalls: Blackwall

12-16.5 is a very large bias-ply truck size used on the 1975 Ford F-350. It is one of the heaviest-duty fitments in the 1975 range and belongs to the specialized 16.5-inch truck category that demands exact wheel compatibility. Available blackwall products from STA include Traxion and Transport versions, with listed 9.75-inch rim widths on some products and stated load capacities up to 3,000 pounds at 45 psi. For owners of one-ton trucks, this size is less about cosmetic variation and more about preserving the correct wheel diameter, heavy-duty stance, and appropriate load-carrying capability.

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

G70-14 is a performance-oriented bias-ply size used on the 1975 Ford GT and 1975 Plymouth Fury. The 70-series profile gives it a lower, wider visual than many standard passenger-car tires of the year, making it important for stance and sidewall character. Available products from Firestone and Goodyear include redline, RWL, and pin-white-stripe treatments, with listed rim-width ranges generally from about 6.0 to 8.0 inches depending on product. This size is especially appealing to buyers trying to recreate a distinctive 1970s performance look rather than a plain touring-car appearance.

H70-14 is a low-profile bias-ply performance size listed here for the 1975 Ford GT. Compared with taller 78-series fitments, this size emphasizes a wider footprint and a more aggressive period stance. No product listing is shown here for H70-14 in the current selection, so the size serves mainly as a precise fitment marker for GT research. For a vehicle in this category, it is important to confirm the wheel width and original-style package before selecting a substitute, since profile changes can have a large effect on appearance and can move the car away from its intended 1975 look.

JR78-14 is an alphanumeric radial size used on selected 1975 Ford and Mercury intermediates, including the 1975 Ford Gran Torino, 1975 Ford Torino & Gran Torino, 1975 Mercury Cougar, and 1975 Mercury Montego. It is a relatively larger 14-inch radial fitment that sits above HR78-14 within the same general sizing family. No products are listed here for JR78-14, so the value of this entry is primarily fitment clarification. Because those same body families may also use HR78-14, matching the exact sidewall designation to the car’s equipment and wheel package is important.

BR78-14 is a radial size associated here with the 1975 Ford Maverick. It falls within the domestic alphanumeric radial system used during the market’s transition away from traditional bias-ply sizing. No product details are shown for this specific size, so owners should focus on confirming whether their Maverick uses BR78-14 or one of the other nearby compact radial fitments seen across the Ford and Mercury lineup. On smaller domestic cars, preserving the intended tire height can have an outsized effect on appearance, especially where wheel openings are visually prominent.

CR78-14 is an alphanumeric radial size used on the 1975 Ford Maverick and 1975 Mercury Comet. It represents a compact domestic radial fitment from the mid-1970s, sitting between smaller and larger 14-inch alpha-numeric radial sizes. Product details are not listed here, so the size should be used primarily to identify the correct application family before comparing alternatives. Since these model lines could appear with multiple tire sizes depending on trim and package, it is best to verify the exact sidewall marking and wheel setup rather than choosing by model name alone.

DR70-14 is a lower-profile radial size used on the 1975 Ford Maverick and 1975 Mercury Comet. Compared with 78-series alternatives, the 70-series format signals a shorter sidewall and a more performance-oriented appearance. No specific product listing is shown here, so this entry is most useful as a fitment identifier for owners narrowing down compact Ford and Mercury applications. Because profile changes are visually obvious on these cars, and can affect gearing feel as well, DR70-14 should be treated as a deliberate size choice rather than a casual substitute for taller 14-inch radials.

CR70-13 is a low-profile domestic radial size listed for the 1975 Ford Mustang. In the context of 1975 fitment, it marks a smaller performance-oriented 13-inch setup that differs substantially from more conventional BR78-13 applications also seen on compact Fords. No products are shown here for CR70-13, so buyers should treat it as a precise size reference when researching Mustang wheel and tire combinations. Because the car could have been changed over time, checking current wheel diameter and width is important before selecting a tire intended to preserve the car’s original-style stance.

Rim Diameter: 13 in  ·  Sidewalls: Narrow Whitewall

195/70R13 is a relatively wide 13-inch radial size used on the 1975 Ford Mustang and 1975 Mazda RX-4. It is a sporty fitment for the era, offering a broader footprint than narrower 155R13 or 165R13 sizes commonly found on compacts. The listed product is a BFGoodrich Silvertown Radial with a 7/16-inch whitewall, 13-inch rim diameter, 5.00 to 6.50-inch rim-width compatibility, and a stated load capacity of 1,246 pounds at 35 psi. For these applications, maintaining proper width and profile is important to keep both the intended stance and wheel fitment in balance.

225R15 is a radial size listed here for the 1975 Ford Thunderbird. It sits in the larger luxury-car radial category and reflects the broad, substantial proportions expected of a mid-1970s personal-luxury coupe. No product details are shown for this size in the current selection, so it should be treated as a specific fitment marker rather than a generalized 15-inch recommendation. Since the Thunderbird is also seen with LR78-15 in this year, confirming the exact tire marking on the vehicle or wheel package is essential before choosing between tall metric and alphanumeric alternatives.

C78-15 is a bias-ply size associated with the 1975 GMC Rally and 1975 GMC Vandura. It belongs to the smaller side of the 15-inch alphanumeric bias-ply range and reflects a van-focused application rather than broad passenger-car use. No current product listing is shown here, so its main role is helping identify the correct fitment family for these full-size GMC vans. Since nearby E78-15, F78-15, G78-15, J78-15, and radial alternatives were also used in the van market, careful verification of the exact tire size remains especially important.

155R12 is a compact metric radial size listed for the 1975 Honda Civic. It represents the narrow, lightweight small-car radial approach that became central to fuel-efficient imports in the mid-1970s. No product details are shown here for this specific size, so it functions mainly as an application identifier for early Civic owners. Because a 12-inch wheel leaves little room for section-width error, staying close to the intended dimensions is especially important for steering ease, ride quality, and body clearance. Small imported cars of this era respond noticeably to even modest tire-size changes.

6.00-12 is a bias-ply size also associated with the 1975 Honda Civic, offering a traditional counterpart to the car’s 155R12 radial fitment. This illustrates how some compact mid-1970s imports straddled older bias-ply sizing and newer radial conventions. No product listing is shown here for 6.00-12, so the main value of this entry is fitment recognition. For an early Civic, confirming whether the car is set up for the bias-ply or radial size can be important, since wheel specification, driving character, and overall appearance may differ between the two approaches.

ER70-15 is a radial size used on the 1975 Jaguar XJ12C, 1975 Jaguar XJ12L, and 1975 Jaguar XJ6. This fitment sits in the performance-luxury end of the 1975 spectrum and combines a lower 70-series profile with a substantial 15-inch package. No product details are shown here for ER70-15, so the size should be used primarily as a precise Jaguar fitment reference. On large European sedans and coupes, maintaining the intended profile helps preserve the car’s proportions, and care should be taken not to substitute a taller touring size without considering the effect on stance and feel.

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

205/70R15 is a classic metric radial size used on the 1975 Jaguar XJ6 and 1975 Maserati Merak. It bridges luxury-touring and sports-car applications, and the available products reflect that range.

Listed rim-width compatibility varies by tire but generally covers common 15-inch passenger-car wheels from 5.0 to 7.5 inches. This size is especially useful for buyers deciding between a cleaner European blackwall presentation and a more pronounced whitewall treatment.

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

600-16 is a bias-ply size listed for the 1975 Jeep CJ6. Although the application count is small within this year, the product coverage is broad, with blackwall and wide whitewall options from BFGoodrich, Coker Classic, Avon, and Firestone. Several products list 4.00 to 4.50-inch rim-width compatibility, underscoring the importance of wheel confirmation on older utility vehicles. This size has a distinctly traditional look and may appeal to owners preserving a vintage-style Jeep stance. Because some CJ models used different 15- or 16-inch fitments, exact model and wheel verification still matters.

10-15 is a bias-ply utility-truck size associated with the 1975 Jeep Cherokee and 1975 Jeep Truck J-10. It represents a wider, more truck-oriented fitment than many standard passenger or SUV sizes from the same year. No current product details are listed here, so the main value of this entry is helping identify the correct application family for full-size Jeep 4x4s. Vehicles in this category are often modified with aftermarket wheels or suspension changes, so confirming wheel width, overall clearance, and actual sidewall markings is especially important before choosing any replacement tire.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

175/70R14 is a radial size listed for the 1975 Lancia Beta. It combines a moderate width with a lower profile than tall 175R14 touring tires, making it a distinctly European mid-1970s fitment with a more sporting balance. The listed product is a Travelstar radial with a narrow whitewall and 14-inch diameter. While this sidewall treatment offers a different visual option than many blackwall European classics, the key fitment factor remains the size itself. On a Beta, preserving the intended profile is important for both appearance and the car’s light, responsive feel.

230R15 is a large radial size used on the 1975 Lincoln Continental, 1975 Mercury Grand Marquis, 1975 Mercury Marquis, and 1975 Mercury Meteor. It belongs to the big luxury-car category and reflects the substantial dimensions expected of full-size domestic sedans and coupes in 1975. No product listing is shown here for this size, so its primary purpose is fitment identification. Since some of these same vehicles also appear with LR78-15, buyers should confirm whether the car uses the tall metric radial format or the alphanumeric radial size before making a selection.

235R15 is a radial size listed specifically for the 1975 Lincoln Continental. As a single-application luxury-car fitment within this year range, it should be treated as a precise size rather than a broad substitute category. No product details are shown here, so the most important step is confirming the tire marking and wheel setup already on the car. Full-size domestic luxury cars from this period often depended on tire profile to deliver the intended visual mass and ride character, so moving to a different format without careful comparison can significantly change the overall presentation.

205/60R14 is a low-profile radial fitment used on the 1975 Lotus Elite and 1975 Lotus Esprit. Within the 1975 field, this is one of the more aggressively proportioned metric sizes, reflecting the sports-car side of the market rather than touring sedans or domestic coupes. Available products include narrow whitewall, blackwall, redline, dual-redline, and RWL styles from Maxxis and BFGoodrich, with listed rim-width ranges generally from 5.00 to 7.50 inches depending on tire. For Lotus applications, width, profile, and wheel suitability are all crucial to preserve the intended balance and visual stance.

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

195/60R15 is a low-profile radial size listed for the 1975 Lotus Esprit. It is one of the more modern-feeling 1975 fitments, emphasizing reduced sidewall height and a clearly sporty stance. Product options include blackwall, wide whitewall, redline, and RWL treatments from BFGoodrich and Michelin, with listed rim-width compatibility generally spanning 5.5 to 7.0 inches. That unusual mix of visual treatments means this size can support either a cleaner European look or a more stylized custom presentation. On an Esprit, however, exact sizing and wheel match should remain the top priority.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, RWL

235/60R15 is a wide, low-profile radial size listed for the 1975 Lotus Esprit. It represents one of the boldest 1975 fitments in both width and profile, making it a very vehicle-specific application. Available products include RWL radials from Cooper and BFGoodrich, plus a blackwall M&H drag radial. Listed rim-width recommendations range from 6.5 to 8.5 inches on several products, with the M&H product specifying a 7-inch rim. Because this size has a strong effect on stance and clearance, it should be matched carefully to the car’s exact wheel and intended road use.

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

600-15 is a bias-ply size listed for the 1975 Volkswagen Beetle. Even by 1975, the Beetle remained tied to a traditional narrow-tire format that rewards restraint in width and profile. Available BFGoodrich classic bias-ply products come in blackwall and wide whitewall versions, with listed 15-inch fitment and rim-width guidance around 4.00 to 5.00 inches depending on product. That makes this size particularly relevant for owners preserving the Beetle’s familiar upright stance and modest wheel width. Because the Beetle also appears with 165R15 radial fitment, confirming construction and size is an important first step.

155D13 is a bias-ply size listed for the 1975 Volkswagen Rabbit. It represents a small-car fitment in a simple numeric-style format during the period when many compact imports were transitioning toward metric radial standards. No product details are shown here for 155D13, so this size is best used as an application identifier before comparing available alternatives in related radial sizes. On a first-generation Rabbit, tire dimensions play an important role in steering effort, fuel-economy character, and body clearance, so maintaining the intended narrow profile is usually more important than simply filling the wheel opening.

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

155/80R13 is a radial size listed for the 1975 Volkswagen Rabbit. It is the radial counterpart to the Rabbit’s small 13-inch economy-car fitment and keeps the narrow, tall-profile look that suits early front-wheel-drive compacts. Available products include narrow and wide whitewall radials from Travelstar, BFGoodrich, Maxxis, and Tornel, with listed rim-width ranges generally from 4.00 to 5.50 inches and load capacities around 959 pounds at 35 psi on several options. This size offers useful visual flexibility while staying within the compact proportions that help define the Rabbit’s original road feel and appearance.

175R15 is a metric radial size listed for the 1975 Volvo 164. It is a traditional tall-profile European touring size and suits the substantial but still relatively restrained wheel-and-tire proportions of a mid-1970s Volvo sedan. No product details are shown here for this specific size, so the main function of the entry is fitment identification. Buyers should confirm whether the car uses 175R15 or the alternate CR78-15 application shown for the same model year. On a car like the Volvo 164, sidewall height and section width contribute meaningfully to both visual balance and highway ride quality.

CR78-15 is an alphanumeric radial size listed for the 1975 Volvo 164. It provides an alternate fitment path from the metric 175R15 size also associated with that model, illustrating how some 1975 cars could straddle sizing systems. No product listing is shown here for CR78-15, so the size is primarily useful as a guidepost when identifying what is currently on the car or what wheel package it uses. Because alpha-numeric and metric radial designations are not always simple one-for-one swaps, careful confirmation of actual tire markings and wheel dimensions is advised.
