1966 Vehicle Tire Fitment Guide

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

560-14 is a bias-ply 14-inch size linked to several 1966 European and Japanese models, including the Alfa Romeo Giulia, Fiat 1100, MG MGB, Nissan 1600, Nissan L320, Nissan L520, and Rover 2000. It belongs to the classic numeric bias-ply sizing pattern still common during the period. Available BFGoodrich products include blackwall, narrow whitewall, and wide whitewall versions, with published rim-width guidance of 3.50 to 4.00 inches and a listed load capacity of 906 pounds at 30 psi on some products. For restoration-minded owners, sidewall style may be just as important as construction type.

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

185R15 is one of the key radial sizes for 1966, covering a broad mix of premium European and British cars such as the Alvis TE 21, Aston Martin DB, Citroen DS, Daimler 2.5 Litre, Jaguar XKE, and Peugeot 404. This is a strong example of radial fitment becoming established on higher-end and technically advanced cars of the era. Product selection includes blackwall, narrow whitewall, and even redline radial choices from Michelin and Coker Classic. Some products specify rim-width ranges from about 4.5 to 6.5 inches, and stated load capacities reach 1355 pounds at 35 psi on certain offerings.

Rim Diameter: 15 in  ·  Sidewalls: Redline, Narrow Whitewall, Goldline, Blackwall, Raised-White-Letter-Blue-Streak, Blue-Dot

775-15 is a bias-ply size serving several larger 1966 American and British applications, including the Chevrolet Corvette, Ford full-size models, Humber Super Snipe, and Studebaker models. It is one of the more style-driven sizes in the year because current product choices include redline, goldline, narrow whitewall, and other period-style sidewall treatments. Brands represented include BFGoodrich and Firestone, with published load capacity figures around 1490 pounds at 32 psi on listed examples. Rim-width guidance varies, with some products listing 4.50 to 5.00 inches and others showing 6-inch applications.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

640-13 is a bias-ply size associated with the 1966 Amphicar Amphicar and Ford-Taunus 17M and 20M. It is a relatively narrow application within the year, but it still highlights how compact and midsize cars in the 1960s could share a 13-inch numeric bias-ply size across very different vehicle types. The listed product is a BFGoodrich wide whitewall with a published load capacity of 1045 pounds at 32 psi and rim-width guidance of 4.00 to 4.50 inches. Owners should confirm whether appearance goals favor the whitewall presentation shown in current offerings.

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

650-13 is a widely shared bias-ply 13-inch size used across ten makes in 1966, including the Austin 1800, Chevrolet Chevy II, Dodge Dart, Ford Falcon, Plymouth Barracuda, Plymouth Valiant, and Triumph 2000. That broad spread makes it one of the more common compact and intermediate bias-ply fitments of the year. Current choices include narrow and wide whitewall styles from Coker Classic and US Royal, with listed load capacities of 1150 pounds at 32 psi and recommended rim widths of 4.50 to 5.00 inches. It is a practical size for shoppers balancing fitment accuracy with visual style.

Rim Diameter: 12 in  ·  Sidewalls: Blackwall

145R12 is a compact radial size used on the 1966 Austin 1100, DKW Junior, MG 1100, and Singer Chamois. It reflects the small-car radial fitment trend seen on many imported economy and city-oriented vehicles of the period. The available product listed for this size is the Michelin MX, a blackwall radial with a 12-inch rim diameter and a published recommended rim width of 4.5 inches. Because 12-inch applications often leave little room for size deviation, owners should verify both wheel dimensions and current vehicle setup carefully, especially on restored cars that may no longer retain stock wheels.

5.50-12 is a bias-ply 12-inch size used across a mix of compact 1966 imports, including the Austin 1100, BMW 700, MG 1100, Singer Chamois, Sunbeam Imp, and Vauxhall Viva. It represents the traditional bias-ply counterpart to some of the small radial sizes used on the same kinds of vehicles. Product availability in the listed range is centered on BFGoodrich, with a wide whitewall option showing a published load capacity of 694 pounds at 30 psi and a 4-inch rim recommendation, plus a blackwall alternative. Small cars often respond noticeably to tire construction changes, so maintaining the correct size matters.

175R13 is a radial size associated with the 1966 Austin 1800, Ford-Taunus 17M, Ford-Taunus 20M, and Triumph 2000. Compared with smaller import radial sizes, it suits somewhat larger sedans with a more substantial footprint while still remaining in a classic 13-inch package. No current product listings are shown here for this size, so the fitment remains useful mainly as a size-reference point when researching the exact application. Because it appears on both British and German cars, it is important not to assume interchangeability with nearby bias-ply numeric sizes unless the vehicle is already documented for that alternative.

Rim Diameter: 10 in  ·  Sidewalls: Blackwall

145R10 is one of the most recognizable small-car radial sizes of 1966, used on the Austin 850, Austin Mini Cooper, Morris Mini Cooper, and Morris Mini Minor. This compact metric radial size is strongly tied to small-wheel British cars where overall diameter, steering response, and wheel clearance are especially sensitive. Product options are all blackwall radials and include Firestone, Kings, Camac, and Dunlop, with some listed load capacities around 694 pounds. For Mini-based applications, confirming the exact wheel width and preserving adequate clearance around suspension and body components is especially important.

5.20-10 is the bias-ply companion size to 145R10 for several 1966 Mini-based applications, including the Austin 850, Austin Mini Cooper, Morris Mini Cooper, and Morris Mini Minor. This size preserves the small numeric bias-ply format familiar to period British compact cars. No specific products are listed here, but the size remains important for identifying vehicles that may have been fitted with either radial or bias-ply construction depending on owner preference or restoration goals. On 10-inch wheel applications, maintaining correct diameter and section width is crucial because even small changes can affect gearing feel, handling, and fender clearance.

7.50-13 is a bias-ply size shown only for the 1966 Austin A 110, making it one of the year’s most specialized applications. Its uncommon fitment means the size itself is the key starting point when researching replacement tires for this model. No product listings are shown here, so the value of the fitment guide is in correctly identifying the application rather than comparing a broad set of current tire options. Because unusual numeric sizes can be confused with adjacent 13-inch fitments, owners should verify the sidewall marking on the existing tire and confirm the wheel before moving forward.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

145R13 is a radial size used on several small 1966 sports cars and compacts, including the Austin A 40, Austin-Healey Sprite, Lotus Elan, Lotus Seven, MG Midget, DAF Daffodil, and Simca 1000. It is a shared import fitment that works across very light vehicles where steering feel and tread profile can have an outsized effect. Available blackwall radial choices include the Michelin XAS-FF and Firestone F560, with some published rim-width guidance of 4.00 to 5.00 inches and listed load capacity of 825 pounds at 44 psi on the Firestone product. This is a size where light-vehicle balance matters.

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

520-13 is a bias-ply size associated with small 1966 British and European cars such as the Austin A 40, Austin-Healey Sprite, DAF Daffodil, Lotus Elan, Lotus Seven, and MG Midget. It is the period-style numeric alternative to 145R13 on several of these applications. Current product choices include Firestone blackwall and multiple Premium Sport narrow whitewall designs, some with listed rim-width guidance around 3.50 to 4.00 inches and load capacity up to 1100 pounds at 60 psi on certain products. Shoppers should note that sidewall style and product series can change the visual character dramatically on these small cars.

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

165R15 is one of the most versatile radial sizes in the 1966 fitment range, serving sports cars, sedans, and touring cars including the Austin-Healey 3000, Porsche 911, Porsche 912, Triumph TR3, TR4 & TR4A, Volvo 122, Volkswagen Fastback, and Volkswagen Squareback. Available products include blackwall, narrow whitewall, and wide whitewall radials from Coker Classic, American Classic, Firestone, and BFGoodrich. Published rim-width guidance commonly falls between 4.50 and 6.00 inches, with listed load capacities around 1168 to 1170 pounds on several products. This size blends broad vehicle coverage with strong product variety.

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

590-15 is a bias-ply 15-inch size shared by a focused group of 1966 British and European sports and touring cars, including the Austin-Healey 3000, Daimler SP 250, Fiat 1800, Morgan Plus 4, Peugeot 404, Triumph TR3, TR4 & TR4A, and Volvo 122. It serves as the numeric bias-ply companion to 165R15 on several of those vehicles. Product selection includes blackwall and wide whitewall BFGoodrich tires along with the Avon Turbospeed, with published rim-width guidance of 4.00 to 4.50 inches on some listings. For owners seeking a more period-oriented driving feel, this size is an important option.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

165R13 is a radial size covering a useful mix of 1966 small and midsize imports, including the Auto-Union Audi, Humber Sceptre, Sunbeam Alpine, Sunbeam Tiger 260, Toyota Corona, and Vauxhall Victor. It sits above smaller 145-series radial fitments and suits cars with a slightly larger footprint or more sporting intent. Current product options are blackwall radials from Michelin and Dunlop, with some listed rim-width recommendations spanning 4.50 to 6.00 inches and load capacity just over 1,000 pounds on the Dunlop offering. This size is widely shared, but final selection should still follow the exact model application.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

590-13 is a bias-ply size used on the 1966 Auto-Union Audi, DKW F102, Ford-Taunus 12M, Toyota Tiara, and Vauxhall Victor. As a compact 13-inch numeric size, it reflects the transitional period when many imported cars could be found with either radial metric sizing or bias-ply numeric alternatives. The listed product is a BFGoodrich wide whitewall with a published load capacity of 970 pounds at 32 psi and recommended rim width of 3.50 to 4.00 inches. For buyers aiming at a period-style look, whitewall width can be a significant visual factor on smaller body shapes.

6.00-14 is a bias-ply size associated with the 1966 BMW 1500 & 1600/4, BMW 1800 & 1800Ti, Nissan L320, and Nissan L520. It bridges passenger-car and light utility applications within the year, which makes careful model confirmation especially important. No current product listings are shown here, so the size serves mainly as a fitment reference for vehicles in this group. Because the same numeric size appears across both sporty sedans and commercial-oriented pickups, wheel width, actual load use, and desired driving character should all be considered before substituting any alternative size or construction.

6.50-15 is a bias-ply 15-inch size used on the 1966 BMW 3200, Nissan Patrol, Peugeot 403, and Peugeot 404. That spread covers both passenger-car and utility-oriented applications, so the size should not be treated as a one-style-fits-all solution. No product details are listed for this size in the current range, but it remains an important identifier for owners of larger sedans and early utility vehicles. Because some vehicles in this group also appear with radial alternatives in nearby sizes, buyers should confirm the exact size already associated with the vehicle rather than assuming easy interchangeability.

5.60-12 is a bias-ply size associated with the 1966 BMW 700, Simca 1000, and Vauxhall Viva. It belongs to the small-car numeric bias-ply family used on compact European models where modest overall dimensions and light curb weight shaped tire choice. No current products are listed here, but the fitment remains useful for identifying cars that were not using the more common 13-inch small-car sizes. Because compact 12-inch applications can be sensitive to section width and overall height changes, matching the correct size format is important when evaluating any replacement tire strategy.

Rim Diameter: 12 in  ·  Sidewalls: Wide Whitewall, Blackwall

520-12 is a bias-ply 12-inch fitment used on the 1966 BMW 700 and DKW Junior. It is a distinctly small-car size, and current product options reflect that compact period presentation. Available BFGoodrich offerings include both blackwall and wide whitewall versions, with the whitewall product listing a load capacity of 694 pounds at 30 psi and a 4-inch rim recommendation. For owners of lightweight European cars, this size can strongly influence stance and authenticity of appearance. Because these cars often run narrow wheels, the published rim guidance is especially worth checking before installation.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall, Whitewall-Redline

815-15 is a larger bias-ply 15-inch size tied to premium 1966 American and British luxury applications, including the Bentley T, Buick LeSabre, Ford full-size models, Ford Thunderbird, Mercury All Models, and Rolls Royce Silver Shadow. Current products are both BFGoodrich offerings, one in narrow whitewall form and another with a whitewall-redline treatment. Published specifications include 15-inch rim diameter, recommended rim widths from 5.00 to 6.50 inches, and a listed load capacity of 1610 pounds at 32 psi. This size suits heavier cars where both appearance and load-carrying requirements deserve close attention.

175R16 is a radial size associated with the 1966 Bristol 408 and Rover 88. It is a relatively specialized fitment within the year and is distinct from the many 14- and 15-inch radial sizes used on passenger cars. No current products are listed here, but the size itself points to vehicles that may require a taller-profile 16-inch radial rather than a more common domestic-style numeric bias-ply tire. Because 16-inch wheel applications can vary significantly in intended use and body clearance, owners should confirm the wheel and vehicle specification carefully before considering any nearby size.

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

600-16 is a bias-ply size used on the 1966 Bristol 408 and Rover 88. It offers a notably broad current product range, including blackwall and wide whitewall tires from BFGoodrich, Coker Classic, Avon, and Firestone. Published rim-width guidance commonly centers on 4.00 to 4.50 inches, and listed load capacities reach about 1400 pounds at 32 psi on several products, with the Avon product showing 1,433 pounds. For owners of British saloons and utility-oriented classics alike, this size provides meaningful flexibility in balancing driving needs with period-style sidewall appearance.

8.85-15 is a large bias-ply size associated with the 1966 Buick Electra 225, Buick Wildcat, and Oldsmobile Toronado. It belongs to the upper end of full-size American 15-inch fitment and signals heavier, more substantial vehicles than the common 14-inch intermediate sizes of the same year. No current products are listed here, so the fitment information is mainly useful for confirming the application before searching further by size. On big American cars, maintaining the correct load-carrying range, section width, and wheel compatibility is important for both appearance and proper road manners.

8.45-15 is a bias-ply size shared by a broad group of 1966 full-size American cars, including Buick LeSabre, Buick Riviera, Buick Wildcat, Chrysler disc brake equipped models, Ford Wagons, and several Mercury applications. It stands out as a large 15-inch fitment used where vehicle weight and trim level move beyond the more common 14-inch intermediate sizes. No specific products are listed here, but the size remains important because many shoppers researching wagons, premium coupes, or brake-package differences need to start with the correct numeric fitment. Confirming wheel size and trim remains essential.

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

760-15 is a bias-ply 15-inch size associated with the 1966 Buick Riviera and Toyota Land Cruiser, a pairing that shows how one numeric size can span very different vehicle roles. Current products include blackwall, narrow whitewall, and wide whitewall choices from BFGoodrich, Coker Classic, and Universal Vintage Tire. Some listings show rim-width guidance from 5.50 to 6.00 inches and load capacities around 1710 pounds at 32 psi. Because this size appears on both a personal luxury car and a utility 4x4, buyers should focus on the specific product style and use case, not just the size alone.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, Redline, Goldline, Blueline

775-14 is one of the most widely shared bias-ply sizes for 1966, appearing on a long list of American intermediates and sporty models such as the Buick Skylark, Chevrolet Chevelle, Dodge Coronet, Ford Fairlane, Mercury Comet, Pontiac GTO, and Rambler Classic, as well as the Jaguar Mark. Product selection is notably varied, with narrow whitewall, redline, and other period-style options from US Royal, BFGoodrich, and Firestone. Listed examples show 14-inch fitment, rim-width guidance around 5.00 to 6.00 inches, and load capacities near 1580 pounds at 32 psi on several products.

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

825-14 is a larger bias-ply 14-inch size used across many 1966 full-size and upper-intermediate American models, including the Buick Sportwagon, Chrysler Newport, Oldsmobile Delta 88, Oldsmobile Starfire, Plymouth Fury, and Pontiac full-size models. Current product listings come from BFGoodrich in blackwall and narrow whitewall versions, all showing a 14-inch rim diameter and recommended rim widths of 5.00 to 6.00 inches. Listed load capacity reaches 1620 pounds at 32 psi. This size is a good example of a common domestic fitment where sidewall appearance can still be tailored without leaving the original size family.

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

735-14 is another highly shared 1966 bias-ply size, used on vehicles such as the Chevrolet Chevelle, Dodge Coronet, Ford Fairlane, Ford Falcon, Plymouth Fury, Pontiac Tempest, Rambler Marlin, and several Mercedes-Benz models including the 250, 280, and 300. That unusual mix makes exact vehicle identification especially important. Current BFGoodrich offerings include blackwall and narrow whitewall versions with published load capacity of 1360 pounds at 32 psi and rim-width guidance of 5.00 to 5.50 inches. It is a common midrange size where wheel width and intended appearance usually guide the final choice.

6.50-14 is a bias-ply size shown only for the 1966 Buick Special. As a single-application fitment within this year, it illustrates how even closely related American models could differ in tire sizing depending on trim or equipment. No current products are listed here, so the size functions mainly as a fitment reference point when verifying a Buick Special before shopping by size. Since Buick Special models also appear with several other associated 14-inch sizes, checking the actual wheel and the tire already on the car is the best way to avoid ordering a nearby but incorrect option.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, Blackwall, Dual-Redline, RWL, Raised-White-Letter-Blue-Streak

695-14 is one of the core 1966 domestic bias-ply sizes, serving a broad range of compacts and intermediates including the Chevrolet Nova, Dodge Dart, Ford Mustang, Plymouth Barracuda, Rambler American, and many others. Product selection is strong, with blackwall, narrow whitewall, and dual-redline offerings from BFGoodrich and US Royal. Published specifications on listed products include 14-inch fitment, recommended rim widths of 5.00 to 6.00 inches, and load capacity of 1230 pounds at 32 psi. For muscle-era and compact-car shoppers, this size offers one of the best mixes of broad vehicle coverage and styling choices.

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

700-14 is a bias-ply size associated here with the 1966 Buick Special and Volkswagen Station Wagon. Even though it appears on only two makes, the applications are very different, which makes vehicle confirmation especially important. Current BFGoodrich products are available in blackwall and narrow whitewall form, both with 14-inch rim diameter, rim-width guidance of 5.00 to 5.50 inches, and a listed load capacity of 1360 pounds at 32 psi. This size is a good reminder that the same numeric designation can serve vehicles with different body styles and usage expectations.

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

820-15 is a heavy-duty bias-ply passenger-car size used on the 1966 Cadillac 75 Series and Cadillac Standard Models. It supports large, substantial luxury-car applications and carries one of the stronger load profiles shown in the year. Product selection is broad and includes blackwall, narrow whitewall, and wide whitewall choices from BFGoodrich, Firestone, and US Royal. Published specifications commonly show 15-inch rim diameter, recommended widths of 6.00 to 6.50 inches, and load capacity around 1920 pounds at 32 psi. This is a size where load capability and sidewall appearance both deserve careful consideration.

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

890-15 is a very large bias-ply 15-inch size shown for the 1966 Cadillac Commercial Series. Its commercial-duty association sets it apart from ordinary passenger-car fitments and makes capacity and wheel compatibility especially important. Current products include blackwall and wide whitewall offerings from Avon and Firestone, with published rim-width guidance of 6.50 to 7.00 inches on some listings. Listed load capacities reach 2500 pounds at 40 psi on the Firestone products, while the Avon listing shows 2,337 pounds. For a long, heavy commercial chassis, choosing a tire with the proper load range is central to the decision.

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

900-15 is a large bias-ply size associated with the 1966 Cadillac Eldorado, Cadillac Standard Models, and Mercedes-Benz 600. It sits among the heaviest passenger-car fitments of the year and offers a distinctive mix of luxury-car and specialty product choices. Current BFGoodrich offerings include narrow whitewall, dual-white-stripe, and triple-whitewall styles, while M&H Racemaster offers a blackwall Vintage Drag Slick in this size family. Listed rim-width guidance typically runs from 6.50 to 7.00 inches, with load capacity around 1920 pounds at 32 psi on the BFGoodrich tires. Exact intended use should guide product selection here.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

855-14 is a full-size American bias-ply 14-inch size used on 1966 Chevrolet full-size models, Chrysler 300, Chrysler New Yorker, Chrysler Newport, Oldsmobile 98 Series, Plymouth Fury, and Pontiac full-size applications. It serves larger cars than the more common 735-14 and 775-14 intermediate sizes, but still stays within the 14-inch domestic family. Listed BFGoodrich products are narrow whitewall designs with load capacity of 1740 pounds at 32 psi and rim-width guidance of 5.50 to 6.00 inches. For big sedans and hardtops, this size often comes down to matching both visual stance and load needs.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

700-13 is a bias-ply size used on the 1966 Chevrolet Corvair, Dodge Dart, Mercedes-Benz 190, Mercedes-Benz 200, Mercedes-Benz 230, Plymouth Barracuda, Plymouth Valiant, and Toyota Crown. That spread makes it one of the more unusual shared sizes of the year, crossing domestic, European, and Japanese applications. The listed product is a Firestone wide whitewall with a published load capacity of 1270 pounds at 32 psi and recommended rim width of 4.00 to 5.00 inches. Because this size appears on cars with very different suspension layouts and weights, the exact make and model should lead the final decision.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

885-14 is a large bias-ply 14-inch size associated with the 1966 Chrysler 300, Chrysler New Yorker, Chrysler Newport, and Oldsmobile 98 Series. It occupies the upper end of domestic 14-inch fitment for the year and is aimed at substantial full-size car applications. The listed product is a BFGoodrich narrow whitewall with a published load capacity of 1860 pounds at 32 psi and a 6-inch rim recommendation. Because this size is more specialized than the common intermediate 14-inch sizes, shoppers should confirm wheel width, vehicle trim, and current sidewall preference before moving to a final product choice.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

135R15 is a small metric radial size used on the 1966 Citroen AMI. It is one of the narrowest passenger-car fitments in the year and reflects the lightweight, efficiency-oriented design philosophy of certain European cars of the period. Current blackwall radial offerings include the Michelin X M+S 89, Michelin ZX, and Firestone F560, with some listed rim-width guidance of 3.50 to 4.50 inches and load capacity around 780 pounds on the Firestone product. Because this size is so specific, owners should stay closely aligned with the documented 135R15 application rather than guessing from similar 15-inch sizes.

180-380 is a radial size associated with the 1966 Citroen DS, Citroen ID, and Citroen SW. This format differs from the more familiar inch-based numeric and metric radial designations seen across most other 1966 vehicles, reflecting a specialized European fitment convention. No current products are listed here, so the primary value is correctly identifying the distinct size family used by these Citroen models. Because sizes in metric wheel-diameter formats are not directly comparable to common 15-inch inch-designated sizes, owners should avoid assuming that a nearby radial size is a straightforward replacement without careful application review.

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

600-13 is a bias-ply size shared by the 1966 DKW F102, Humber Sceptre, Singer Gazelle, Singer Vogue, Sunbeam Alpine, Sunbeam Minx, Sunbeam Rapier, Sunbeam Tiger 260, and Toyota Corona. This makes it one of the more widely used imported 13-inch bias-ply sizes in the year. Current BFGoodrich products are offered in wide whitewall and narrow whitewall styles, with a published load capacity of 1010 pounds at 32 psi and recommended rim widths of 4.00 to 4.50 inches. It is a useful size for shoppers who want a traditional period look on compact sports sedans and small sporting cars.

5.50-13 is a bias-ply size associated with the 1966 DKW Junior and Simca 1000. It fits into the small European compact class and is distinct from the larger 600-13 and 650-13 sizes used elsewhere in the year. No products are listed for this size here, so the fitment value lies mainly in identifying the correct narrow 13-inch numeric tire family. Because compact imported cars from this period often share similar-looking wheel diameters but not the same section widths, confirming the exact sidewall marking and the intended stance of the car is especially important.

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

560-13 is a Bias Ply tire size associated with DKW Junior, Fiat 1200 & 1500, Fiat 1300 & 1500, Ford Cortina, Ford-Taunus 12M, Toyota Tiara, Triumph Spitfire, Triumph Sports Six, and Vauxhall Victor & VX 4/90 for 1966. Confirm the rim diameter and intended use before choosing a replacement tire.

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

700-16 is a bias-ply size shown for the 1966 Daimler 4.5 Litre. It is a substantial 16-inch fitment with a broad range of current product options, including blackwall and wide whitewall offerings from Lester, Avon, BFGoodrich, and Firestone. Published specifications include rim-width guidance of 4.50 to 5.50 inches on several products and load capacities reaching 1900 pounds at 36 psi on the BFGoodrich tire, with 1,874 pounds listed on the Avon commercial-style option. This size can support very different appearance goals, from elegant whitewall presentation to a more understated blackwall look.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

205R14 is a radial size used on the 1966 Ferrari 275, Ferrari 320, and Jaguar Mark. It is one of the wider 14-inch radial fitments in the year and is clearly aimed at higher-performance grand touring applications rather than ordinary passenger sedans. The listed product is the Michelin XWX blackwall radial, with a published rim-width range of 5.50 to 7.50 inches. Because this size appears on prestigious sporting and luxury cars where balance and handling matter, wheel width and overall vehicle setup should be checked carefully before purchase rather than assuming all 14-inch radial wheels are suitable.

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

205R15 is a radial size linked to several upscale and performance-focused 1966 applications, including the Ferrari 330, ISO Grifo, ISO S4 Fidia, Maserati Mexico, Maserati Mistral, Maserati Quattroporte, Maserati Sebring, and Rolls Royce Silver Shadow. Current products include an Avon blackwall radial and a Phoenix wide whitewall radial, giving owners a choice between a cleaner sporting appearance and a more formal luxury presentation. Listed rim-width guidance on the Phoenix product is 5.50 to 6.00 inches, with stated load capacity of 1609 pounds at 34 psi. This is a specialized GT and luxury-car fitment, not a general 15-inch substitute.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

155R14 is a radial size used on the 1966 Fiat 1100, Lancia Fulvia, and Morris Minor. It represents a classic small-displacement European radial fitment, offering a step up from the very smallest 12- and 13-inch sizes while remaining narrow and efficient by modern standards. Current blackwall radial choices include the Michelin X and Firestone F560, with some published rim-width guidance of 4.00 to 5.50 inches and a listed load capacity of 990 pounds at 44 psi on the Firestone. This size is well suited to owners seeking an era-appropriate radial format for compact touring and saloon cars.

520-14 is a bias-ply size associated with the 1966 Fiat 1100, Fiat 1500, Lancia Fulvia, and Morris Minor. It is a compact 14-inch numeric size that serves as the bias-ply counterpart to some of the radial fitments used on these cars. Current products are Premium Sport narrow whitewall tires in several design variations, with some listings showing recommended rim widths of 3.50 to 4.00 inches and load capacity of 1230 pounds at 60 psi. Because all current listings emphasize a whitewall presentation, owners should consider how that appearance aligns with the specific character of the car being restored or driven.

155R13 is a radial size used on a wide group of 1966 compact European cars, including Fiat 1200 & 1500, Fiat 1300 & 1500, Ford Cortina, Ford-Taunus 12M, Opel Kadett, Triumph Spitfire, Triumph Sports Six, and Vauxhall Victor & VX 4/90. Current product choices are blackwall radials from Michelin and Dunlop, with some listed rim-width guidance spanning 4.00 to 5.50 inches and published load capacity of 937 pounds on the Dunlop product. This is one of the more useful import radial sizes of the year for owners seeking a traditional tread and profile without stepping into larger fitments.

145R14 is a radial size associated with the 1966 Fiat 1500 and Lancia Fulvia. It is a narrow, compact radial fitment that sits between the smallest 13-inch import sizes and the more common 155R14 class. Current blackwall radial options include the Firestone F560 and Camac BN313, with the Firestone listing a published load capacity of 880 pounds at 44 psi and rim-width guidance of 4.00 to 5.00 inches. Since this size is tied to relatively light European cars, maintaining the correct narrow profile helps preserve steering feel and body clearance.

5.90-14 is a bias-ply size used on the 1966 Fiat 1500 and MG MG. It is a relatively focused application and serves as a period-style numeric alternative to radial sizing on smaller sports and saloon cars. The listed products include a BFGoodrich blackwall and a BFGoodrich wide whitewall, both with published load capacity of 1150 pounds at 32 psi and rim-width guidance centered on 4.00 to 4.50 inches, though one blackwall listing extends to 5.00 inches. For buyers seeking an authentic-looking bias-ply presentation, this size offers a straightforward period appearance without requiring a large wheel.

175R14 is a radial size shown for the 1966 Fiat 1800. Though it appears on only one application here, current product choice is solid, with blackwall radial options from Michelin and Vredestein. Published specifications include 14-inch rim diameter, rim-width guidance from roughly 4.5 to 6.0 inches on some products, and a listed load capacity of 1,235 pounds at 51 psi on the Vredestein Sprint Classic. This size occupies a useful middle ground for a midsize European touring car, and the available products lean toward a clean, sporting blackwall presentation rather than decorative sidewall treatments.

6.40-14 is a bias-ply size shown only for the 1966 Fiat 1800. It is the numeric bias-ply counterpart to the same model’s radial fitment and reflects the transitional tire landscape of the mid-1960s, when some vehicles could be encountered with either construction family. No current products are listed here, so the size remains most helpful for identifying the correct fitment direction before shopping further. Since the Fiat 1800 also appears with 175R14, owners should verify whether the car is being kept in its existing construction type or evaluated for another period-appropriate option.

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

185R14 is a radial size used on the 1966 Fiat Dino, Mercedes-Benz 250, Mercedes-Benz 300, and Volkswagen Station Wagon. It covers both sporting and practical applications, which makes exact fitment confirmation important even though the size itself is shared. Product options include blackwall and narrow whitewall radials from Michelin, Phoenix, and Vredestein. Published rim-width guidance ranges from about 4.00 to 6.50 inches depending on the tire, and stated load capacities reach 1323 pounds at 35 psi on the Phoenix listing. This size offers one of the better mixes of classic radial choices and sidewall presentation.

7.35-15 is a bias-ply size associated with the 1966 Ford full-size models, Studebaker All Models, Studebaker Wagons, and Volvo 122. That combination shows how a common 15-inch numeric size could bridge American full-size cars and an imported sedan. No current products are listed here, so the size serves mainly as a fitment anchor when narrowing down the exact application. Because Volvo 122 also appears with other associated sizes, and Ford full-size cars can vary by trim, it is wise to verify the actual wheel and current tire before treating 7.35-15 as the automatic choice.

8.25-15 is a bias-ply size tied to the 1966 Ford full-size models and Ford Thunderbird. It sits in the larger full-size American 15-inch family and indicates a more substantial tire than the common intermediate 14-inch sizes used elsewhere in the year. No products are listed here, but the size remains important because full-size Ford applications can overlap with other 15-inch dimensions depending on body style and trim. Since the Ford line for 1966 includes several associated 15-inch sizes, checking the specific model, current wheel, and any suspension or wheel changes is especially important.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall

855-15 is a bias-ply size shown for the 1966 Ford Wagons. As a wagon-specific fitment, it points toward larger load-carrying demands than many passenger-car applications of the same era. Current BFGoodrich products are narrow whitewall designs with published rim-width guidance of 6.00 to 6.50 inches and listed load capacity of 1710 pounds at 32 psi. The sidewall options are subtle rather than dramatic, which suits many full-size family-car restorations. Because wagons are often modified for cruising or hauling, it is worth confirming that the existing wheels still match the tire’s published fitment range.

215R15 is a radial size shown only for the 1966 ISO Grifo. It is one of the most specialized and performance-oriented 15-inch fitments in the year, reflecting the requirements of an Italian GT rather than a broad production-car application. No current products are listed here, so the fitment information is primarily useful for identifying the correct size category when researching replacements. Because 215R15 is not a common general-purpose classic size in this year’s range, owners should avoid assuming nearby 205R15 products are interchangeable without first verifying wheel width, clearance, and the intended driving setup.

9.15-15 is a large bias-ply size associated with the 1966 Imperial All Sedans, Imperial Convertibles, and Lincoln Continental. It represents one of the biggest passenger-car fitments in the year and is clearly aimed at very large American luxury vehicles. No current products are listed here, so the size mainly serves as a crucial fitment reference when sorting through big-car options. Since these heavy vehicles can be sensitive to both load capacity and overall stance, confirming the tire size on the vehicle, the wheel dimensions, and whether the car still retains its original wheel setup is especially important.

175-400 is a radial size associated only with the 1966 Lancia Flaminia. This metric wheel-diameter format is notably different from standard inch-based radial and bias-ply sizes, making it a distinctly specialized fitment within the year. No current products are listed here, but the size itself is vital for accurate identification because it should not be treated as a simple variation of 14- or 15-inch sizing. For owners of unusual European grand touring cars, correct size notation matters just as much as construction type, especially when evaluating wheels, clearances, and specialized replacement options.

175R400 is the other radial fitment associated with the 1966 Lancia Flaminia. Like 175-400, it uses a metric wheel-diameter format rather than a conventional inch-based designation, which places it in a very specialized corner of the 1966 tire landscape. No products are listed here, so the fitment value lies in correctly preserving the size reference for the vehicle. Because metric-diameter wheel systems can be misunderstood when compared with standard 15-inch fitments, owners should use caution and verify the wheel type already on the car before exploring replacement tire options.

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

GR70-15 is a radial fitment shown for the 1966 Maserati Ghibli and stands out because the listed products are bias-look radial designs rather than conventional 1960s metric radials or numeric bias-ply tires. Available Goodyear products include RWL and pin-white-stripe sidewall treatments, with published rim-width guidance generally in the 7.0 to 8.0 inch range. This size is clearly aimed at a more performance-focused presentation and sits apart from the year’s smaller imported fitments. Because it appears alongside 205R15 on the same model family, exact wheel and intended appearance should drive the final choice.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

185R13 is a radial size used on the 1966 Mercedes-Benz 190, Mercedes-Benz 230, and Toyota Crown. It is wider than many compact import radial sizes of the same wheel diameter and suits cars with a somewhat larger footprint and more substantial curb weight. The listed product is a Michelin XAS-FF blackwall radial. No rim-width guidance is published in the product summary for this size, so buyers should focus on confirming the exact wheel and overall application. This is a good example of a 13-inch radial fitment that is more sedan-oriented than economy-car oriented.

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

725-13 is a bias-ply size shown for the 1966 Mercedes-Benz 200. It is a specialized 13-inch application and not one of the widely shared domestic compact sizes seen elsewhere in the year. Current BFGoodrich products include both blackwall and wide whitewall versions, with the whitewall tire listing a load capacity of 1360 pounds at 32 psi and recommended rim widths of 4.50 to 5.50 inches. For owners of a Mercedes-Benz 200, this size highlights the need to match the specific model rather than assuming all 1966 Mercedes-Benz sedans shared the same tire family.

195R14 is a radial size shown only for the 1966 Mercedes-Benz 280. It is a distinct fitment within the Mercedes-Benz range for the year and reflects how tire dimensions could vary even among closely related sedans. No products are listed here, so the size entry is most valuable as a fitment checkpoint before shopping by application or pursuing a model-correct replacement path. Because the Mercedes-Benz line also includes 185R14 and 735-14 fitments elsewhere, owners should verify the exact model and wheel setup before treating any nearby 14-inch size as an equivalent.

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

700-15 is a bias-ply size associated with the 1966 Nissan Patrol. Current products span both passenger-style and utility-oriented choices, including blackwall and wide whitewall versions from Firestone and BFGoodrich, plus the STA Traxion with a military and truck-focused attribute. Published rim-width guidance on several products is 5.00 to 5.50 inches, and listed load capacities reach 1700 pounds at 32 psi on some passenger-style options. Because this size appears on a rugged utility vehicle rather than a typical sedan, intended road use should play a major role in choosing between a more decorative sidewall and a traction-oriented tire.

6.45-14 is a bias-ply size shown only for the 1966 Rambler American. As a single-model fitment, it underscores how compact American cars could use a narrower 14-inch tire than their intermediate counterparts in the same year. No current products are listed here, so the size acts mainly as a fitment identifier for Rambler American owners. Since nearby sizes such as 695-14 are common across many models, it is especially important not to assume they are interchangeable without verifying wheel width, current vehicle stance, and whether the car still uses its original wheel configuration.

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

145R15 is a radial size associated with the 1966 Renault Renault. It is a narrow import radial fitment and occupies a similar compact-car niche to other small European sizes of the period, but with a 15-inch wheel. Current products include blackwall radials from Firestone and Michelin, plus a BFGoodrich Silvertown Radial wide whitewall option. Some listings show rim-width guidance from 3.50 to 5.00 inches and load capacity of 935 pounds at 44 psi on the Firestone product. For owners deciding between appearance and understated touring style, this size offers both blackwall and whitewall radial directions.

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

750-16 is a bias-ply size shown for the 1966 Rover 109. It is a substantial 16-inch fitment appropriate to a utility-oriented vehicle and is supported by a diverse product range. Available choices include blackwall and wide whitewall tires from Firestone, Lester, and BFGoodrich, with published rim-width guidance of 5.00 to 6.00 inches and listed load capacities reaching 1850 pounds at 48 psi on some products. Because the Rover 109 is often used or restored in ways that differ from ordinary passenger cars, buyers should pay close attention to the tire’s intended character, not just the size marking.

155R12 is a radial size associated with the 1966 Simca 1000 and Sunbeam Imp. It is a compact radial fitment for small, light vehicles and differs from the 145-series and bias-ply 12-inch sizes used elsewhere in the year. No current products are listed here, so the size entry is most useful for confirming the correct application before searching for a replacement. Since both of these cars are sensitive to tire diameter and tread profile, owners should be careful not to substitute a nearby 12-inch size without checking how it may affect gearing feel, steering response, and body clearance.

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

H78-15 is a bias-ply size associated with the 1966 Toyota Land Cruiser. It stands apart from many passenger-car fitments because current product choices include both whitewall passenger-style tires and the STA Traxion, which carries a military and truck-oriented attribute. Available Coker Classic products list wide whitewall styles, while the STA option is a blackwall traction-focused tire. Published rim-width guidance runs from 5.50 to 7.00 inches, with load capacities around 1770 to 1830 pounds on listed products. This size is a clear case where intended use matters as much as appearance.

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

600-15 is a bias-ply size used on the 1966 Volkswagen Fastback and Volkswagen Squareback. It is a focused 15-inch fitment with straightforward current choices from BFGoodrich in blackwall and wide whitewall form. Listed specifications include load capacity of 1150 pounds at 32 psi and rim-width guidance around 4.00 to 5.00 inches depending on the product. Because these Volkswagen models also appear in the guide with radial-type applications in other size families, it is worth confirming whether the vehicle is being kept in a bias-ply configuration or matched to an existing wheel-and-tire setup.
