165R14 is a radial size tied to the 1956 Austin A 55 and 1956 Fiat 1400. Though limited to two applications, it is supported by several respected radial choices from Pirelli, Michelin, and Vredestein. All listed products use a Blackwall sidewall, but they differ in series and published wheel recommendations, with some showing rim-width ranges from 4.0 to 6.0 inches. This size suits owners who want a road-friendly radial fitment on mid-sized European sedans, but because the application list is narrow, it is wise to confirm the exact vehicle model and wheel dimensions before ordering.

5.90-14 is the bias-ply counterpart used on the 1956 Austin A 55 and 1956 Fiat 1400. The numeric bias-ply format is typical of the period and should be treated as its own fitment category rather than casually swapped with another size without checking wheel and clearance details. Product details are not shown here for current offerings, but this size remains relevant for owners who want to retain traditional bias-ply construction and vintage stance on these two applications. For restoration-focused projects, construction type can be just as important as the size designation itself.

Several products specify 6.00- to 6.50-inch rim widths and a published maximum load capacity of 1,920 pounds at 32 psi, appropriate for heavier full-size applications.

195R15 is a specialized radial fitment associated with the 1956 Borgward Hansa. As one of the larger radial sizes in the 1956 European field, it points to a vehicle requiring more section width than the common 155R15 or 165R15 applications. Product details are not listed here, so buyers researching this size should pay close attention to the exact wheel and body configuration of the car. On a restored or modified Hansa, even a correct nominal size can be affected by wheel changes, making careful measurement and comparison especially important before final tire selection.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

165R13 is a radial size used on the 1956 Borgward Isabella and 1956 Ford Consul Eotta. This is a compact but slightly wider 13-inch radial than many small-car applications of the period, and it benefits from multiple current Blackwall options from Michelin and Dunlop. Listed products include Michelin XAS-FF, Michelin XAS, and Dunlop SP Sport Aquajet, with some showing 4.50- to 6.00-inch rim-width compatibility and a published load capacity of 1,047 pounds on one Dunlop offering.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

590-13 is a bias-ply size shared by the 1956 Borgward Isabella and 1956 Ford Consul Eotta. Compared with radial alternatives used on some cars from the same year, this size preserves a more traditional 1950s tire construction and look. Current product coverage shown here centers on a BFGoodrich Wide Whitewall tire, with listed fitment for a 13-inch rim and a 3.50- to 4.00-inch rim-width range. The stated maximum load capacity is 970 pounds at 32 psi. Because options are limited, this size is especially relevant for owners prioritizing a specific vintage sidewall appearance.

175R13 is a radial size found on several 1956 sedans and wagons, including the 1956 Ford Zephyr, 1956 Holden FE, 1956 Mercedes-Benz 219, 1956 Mercedes-Benz 220, 1956 Opel Caravan & Wagon, 1956 Opel Kapitan, and certain 1956 Borgward Isabella applications. It represents a relatively broad 13-inch radial for medium-sized cars of the period. Product details are not listed here, but this fitment stands out because it spans multiple makes while remaining more specialized than smaller 13-inch sizes. On vehicles that have seen wheel substitutions over time, exact diameter and width checks are worthwhile before committing to replacement tires.

The current products shown are Coker Classic Wide Whitewall tires in two whitewall widths. Listed specifications include 6.00- to 6.50-inch rim-width compatibility and a maximum load capacity of 1,800 pounds at 32 psi, fitting the needs of heavier luxury-class cars.

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

890-15 is a very large bias-ply fitment associated specifically with the 1956 Cadillac 86 Series. This is one of the most specialized passenger-car sizes in the 1956 lineup and is supported by products from Firestone and Avon. Sidewall choices include Blackwall and substantial Wide Whitewall presentations, which are visually appropriate for dramatic mid-1950s luxury styling. Listed specifications include a 15-inch rim, 6.50- to 7.00-inch wheel-width range on certain Firestone offerings, and published load capacities from 2,337 pounds to 2,500 pounds, reflecting the needs of a very heavy, premium-class application.

165-400 is a millimetric radial size used on 1956 Citroen and Lancia applications, including the 1956 Citroen 11, 1956 Citroen DS, 1956 Citroen ID, 1956 Lancia Aurelia, and 1956 Lancia Flaminia. The 400 designation refers to the wheel’s metric diameter, so correct wheel identification is essential. While current product details are not shown here for this exact format, the size remains important because these cars sit outside the more familiar inch-based American and British sizing patterns of the same year. Owners of European collector cars should verify both the exact size marking and wheel type before selecting replacements.

155-400 is a radial millimetric size used on the 1956 Citroen 11 and 1956 Peugeot 203. Like other 400-series fitments, it requires a metric-diameter wheel and should not be treated as a direct substitute for a similarly sized inch-based tire. This type of sizing is a reminder that 1956 fitment can vary widely between American and continental European vehicles. Product specifics are not listed here, so buyers should focus on confirming the exact wheel diameter marking, tire construction, and intended use. That extra verification helps avoid mistakes on cars with unusual or mixed restoration histories.

185-400 is a radial millimetric fitment used on the 1956 Citroen 11 and 1956 Peugeot 203. Compared with smaller 400-series sizes, it suggests a wider section for the vehicles that use it, but the key point remains the same: this is a metric-diameter tire format that must match the correct wheel. Product details are not listed here, making wheel confirmation even more important before shopping by appearance or brand. For owners working on French collector cars, this size stands apart from common 15- and 16-inch fitments and should be researched with attention to both the sidewall marking and wheel specification.

125-400 is a highly specialized radial size associated with the 1956 Citroen CV. It is one of the narrowest and most distinctive fitments in the entire 1956 range, reflecting the lightweight, economy-focused character of the vehicle rather than the larger luxury and performance sizes seen elsewhere that year. Because this is a metric-diameter format, proper wheel matching is critical. Product details are not shown here, so buyers should verify the exact sidewall designation on the vehicle before beginning product selection. On uncommon applications like this, careful identification matters more than broad year-based assumptions.

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

700-16 is a larger bias-ply size used on the 1956 Daimler Four-Light Saloon and 1956 Willys 226. It has broad product representation relative to its application count, with Blackwall and Wide Whitewall choices from Lester, Avon, BFGoodrich, and Firestone. One listed option also carries a more utility-oriented Traction Mileage designation, giving this size an interesting range from formal passenger-car presentation to more robust service character. Published specifications on select products include 4.50- to 5.50-inch rim widths and load capacities from about 1,800 to 1,900 pounds, making it suitable for heavier 16-inch applications.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

155R14 is a radial size used on the 1956 Fiat 1100 and 1956 Simca Aronde. It is a compact, road-friendly fitment that reflects the smaller European sedans of the period rather than the larger-section American tires common elsewhere in 1956. Current Blackwall radial choices come from Michelin and Firestone, with one Firestone listing a 4.00- to 5.50-inch rim-width range and a 990-pound maximum load capacity at 44 psi. This size is a good example of how 1950s import fitment often combines narrow tread dimensions with relatively tall sidewalls, making correct size identification important for both appearance and handling.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

520-14 is a bias-ply size associated with the 1956 Fiat 1100. The current product lineup shown here centers on Premium Sport narrow whitewall tires in multiple whitewall widths and design variations, making this a style-conscious option within a relatively small fitment category. Some products list a 14-inch rim, 3.50- to 4.00-inch rim-width range, and a published maximum load capacity of 1,230 pounds at 60 psi. Because the application list is narrow and the product family emphasizes appearance, owners should confirm both wheel dimensions and the visual look they want before making a final choice.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

175R14 is a radial fitment used on the 1956 Fiat 1400 and 1956 Fiat 1900. It is supported by Blackwall products from Michelin and Vredestein, including both Sprint and Sprint Classic series alongside Michelin XAS. Some listed products include rim-width ranges from 4.5 to 6.0 inches and published load capacity up to 1,235 pounds at 51 psi. For owners of larger mid-1950s Fiats, this size offers several recognized radial choices without moving away from the vehicle’s basic period proportions. As always with older cars, wheel width and current vehicle configuration should be checked before selection.

6.40-14 is a Bias Ply tire size associated with Fiat 1400 and Fiat 1900 for 1956. Confirm the rim diameter and intended use before choosing a replacement tire.

Rim Diameter: 12 in  ·  Sidewalls: Blackwall

135R12 is a small radial size associated with the 1956 Fiat 600. The listed current option is a Firestone F560 Blackwall radial, making this a very focused fitment for one of the year’s most compact applications. Its 12-inch rim diameter sets it apart from the many 13-, 14-, and 15-inch tires used elsewhere in 1956, and it highlights how wide the year’s fitment spread really is. Because compact cars can be particularly sensitive to tire dimensions, owners should verify wheel size and available clearance carefully, especially if the car has non-original wheels or suspension changes.

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

520-12 is the bias-ply counterpart associated with the 1956 Fiat 600. Current products include BFGoodrich Blackwall and Wide Whitewall versions, giving owners a simple but meaningful visual choice within this small-size category. Listed specifications include a 12-inch rim diameter, and one product shows a 4-inch rim width with a 694-pound maximum load capacity at 30 psi. This size is especially relevant for restoration-minded projects where preserving a compact bias-ply profile matters. Because there are few 12-inch vintage fitments in the 1956 field, buyers should be careful to match the exact size rather than choosing by general appearance.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

155R13 is a radial size used on the 1956 Ford-Taunus 12M, 1956 Ford-Taunus 15M, 1956 Opel Olympia, and 1956 Standard Ten. Current Blackwall radial offerings come from Michelin and Dunlop, with one Dunlop product listing a 937-pound maximum load capacity and Michelin specifying a 4.00- to 5.50-inch rim-width range. This is a useful fitment for compact European sedans that need a slightly fuller 13-inch radial than the narrowest small-car sizes of the period. For cars restored over many decades, it is smart to confirm whether the vehicle remains on its correct wheel diameter before ordering.

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

560-13 is a bias-ply size shared by the 1956 Ford-Taunus 12M, 1956 Ford-Taunus 15M, 1956 Metropolitan 1500, 1956 Opel Olympia, and 1956 Standard Ten. Product options include Narrow Whitewall and Wide Whitewall styles from BFGoodrich and Firestone, giving this small 13-inch size a distinctly period presentation. Several products list 3.50- to 4.50-inch rim-width compatibility and a maximum load capacity of 850 pounds at 30 psi. This size is a good example of how smaller 1956 cars often used narrow bias-ply tires where sidewall styling can strongly influence the finished restoration look.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

135R15 is a radial size used on the 1956 Hillman Husky, 1956 Lloyd LT, and 1956 Saab 92. It is a notably narrow 15-inch fitment suited to lightweight European cars. Current Blackwall radial choices include Michelin X M+S 89, Michelin ZX, and Firestone F560, with some products listing 3.50- to 4.50-inch rim-width compatibility and load capacities around 780 pounds. Because this size combines a tall sidewall with a narrow section, it affects both stance and steering feel on small cars. Exact wheel width should be checked, particularly on survivors that may have accumulated replacement wheels over time.

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

500-15 is a bias-ply size used on the 1956 Hillman Husky, 1956 Lloyd LT, and 1956 Saab 92. Current products include BFGoodrich Blackwall and Wide Whitewall passenger-car tires, plus a Firestone Dirt Track Ribbed Front option that serves a more specialized purpose. Published specifications include a 15-inch rim, a 3-inch wheel width on some BFGoodrich products, and load capacities around 675 to 700 pounds at 32 psi. For owners shopping this size, intended use matters: a standard vintage touring look is different from a competition-oriented ribbed-front application, even when the nominal size matches.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall

550-15 is a bias-ply size used on the 1956 Hillman Mark VIII, 1956 Holden FJ, 1956 MG Magnette, 1956 MG Midget, 1956 Morris Oxford, and 1956 Wolseley 4/44. The current product shown is an Excelsior Blackwall bias-ply with a listed 15-inch rim diameter and 3.00- to 3.50-inch wheel-width range. This is a focused, traditional fitment for smaller British and Commonwealth sedans and sports models that benefit from a classic bias-ply profile. Since product choice is limited here, owners often place extra emphasis on confirming wheel width and the overall appearance they want for the finished car.

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

700-15 is a larger bias-ply size associated with the 1956 Humber Super Snipe. Although its application list is narrow in this year, the product range is much broader, with Blackwall and Wide Whitewall offerings from Firestone, BFGoodrich, and STA. One STA tire is identified within a military and truck series, so buyers should distinguish between passenger-car presentation and utility-oriented tread intent. Several listed products include a 15-inch rim diameter, 5.00- to 5.50-inch rim-width range, and maximum load capacities around 1,700 pounds at 32 psi, making this a substantial fitment for a large saloon.

4.25-15 is a narrow bias-ply size used on the 1956 Lloyd LC, 1956 Lloyd LP, and 1956 Lloyd LS. It is one of the smallest and most specialized inch-based sizes in the 1956 lineup, reflecting lightweight microcar or economy-car applications rather than conventional mid-size sedans. Product details are not shown here, so exact wheel and size-marking confirmation are especially important when shopping this fitment. On uncommon vehicles, even small differences in wheel diameter or section width can affect drivability and body clearance, so owners should approach selection carefully and avoid substituting by guesswork.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

700-13 is a bias-ply size associated with the 1956 Mercedes-Benz 180 and 1956 Mercedes-Benz 190. The listed current product is a Firestone Wide Whitewall, giving this size a distinctly mid-century visual presentation. Published specifications include a 13-inch rim diameter, 4.00- to 5.00-inch rim-width range, and a maximum load capacity of 1,270 pounds at 32 psi. This size is notable because it serves relatively substantial sedans on a 13-inch wheel, different from the smaller narrow-section 13-inch tires found on some economy cars. Buyers should confirm whether their car is using this bias-ply fitment or the alternate radial size available on certain models.

185R13 is a radial size associated with the 1956 Mercedes-Benz 190. The listed current product is a Michelin XAS-FF Blackwall radial, making this a very focused single-application fitment within the 1956 range. Its relatively wide section on a 13-inch wheel distinguishes it from the more common 145R13 or 155R13 sizes used on smaller cars. Because options are limited and the size is specialized, owners should verify the exact wheel diameter and current configuration of the vehicle before ordering. This is the kind of fitment where a careful, model-specific check is more useful than relying on general year-based assumptions.

6.70-13 is a bias-ply size used on the 1956 Mercedes-Benz 220. This numeric format reflects period bias-ply sizing practice and should be matched carefully rather than approximated by a modern-looking substitute without wheel and clearance checks. Product details are not listed here, but the size remains important because it highlights how one make in 1956 could use different 13-inch fitments across closely related models. For owners of collector Mercedes-Benz sedans, the key considerations are the exact sidewall marking, the desired construction type, and whether the car still retains its intended wheel specification.

7.10-15/6 is a bias-ply size used on the 1956 Mercury All Models Except:, 1956 Pontiac 860 & 870, 1956 Pontiac Safari, 1956 Pontiac Star Chief, 1956 Studebaker Classic, and 1956 Studebaker Golden Hawk & Classic. The slash-six marking is a period convention that identifies a specific fitment rather than a styling detail, so it should be treated carefully during replacement research. Product details are not shown here for this exact format, but within 1956 applications it falls into the larger American passenger-car group where load, stance, and wheel width all matter. Exact size confirmation is recommended before choosing a substitute.

Rim Diameter: 16 in  ·  Sidewalls: Blackwall

525-16 is a bias-ply size used on the 1956 Morgan 2+4 Seater and 1956 Morgan Coupe. The listed product is a Deka Blackwall tire from the Deka Classic Truck series, with a published 16-inch rim diameter, 4.00- to 4.25-inch rim-width range, and a 902-pound maximum load capacity at 30 psi. This is a narrow, specialized fitment that reflects the lightweight character of the Morgan applications rather than mainstream postwar sedan sizing. Because both the vehicle and the tire size are niche by modern standards, careful wheel measurement and intended-use consideration are especially worthwhile during selection.

135R14 is a radial size associated with the 1956 Morris Minor. It is one of the year’s more specialized compact radial fitments, reflecting the modest dimensions and lightweight design of the Minor. Product details are not listed here, but the size itself signals a narrow-section tire on a 14-inch wheel, very different from the broad 15-inch and 16-inch tires used on American and luxury European cars from the same year. On a Morris Minor, maintaining the correct general proportions can have a noticeable effect on steering and appearance, so exact size verification is important before choosing any replacement.

5.00-14 is the bias-ply fitment associated with the 1956 Morris Minor. In the context of 1956 tire selection, it represents the traditional counterpart to the Minor’s radial option and suits owners seeking a more period-oriented construction and look. Product details are not shown here, so the emphasis should be on confirming the exact wheel size and whether the car is intended for restoration presentation, regular driving, or a mix of both. On a small, lightweight vehicle, staying close to the correct dimensions helps preserve steering response, body clearance, and the visual balance that makes these cars look right.

145-400 is a radial millimetric size used on the 1956 Panhard Dyna. As with other 400-series fitments, the key consideration is the wheel’s metric diameter, which makes exact matching essential. This is a very specialized French application that differs sharply from the inch-based American and British sizing seen throughout the rest of the 1956 field. Product details are not listed here, so owners should begin by confirming the sidewall size marking and wheel specification already on the car. For uncommon continental applications, precision matters more than trying to generalize from similar-looking sizes.

175-400 is a radial millimetric size associated with the 1956 Peugeot 203. This format uses a 400mm wheel diameter, so it belongs to a distinct family of European fitments that should not be confused with 15- or 16-inch tires. While current product details are not shown here, the size remains important for owners preserving the correct general fitment style of a French postwar sedan. Because millimetric wheel diameters are less familiar today, careful identification is essential before shopping by brand or sidewall appearance. Confirming the exact sidewall marking is the best first step on this type of application.

8.00-17 is a large bias-ply fitment associated specifically with the 1956 Rolls Royce Phantom. It stands apart from most 1956 passenger-car sizes by combining a substantial section width with a 17-inch rim, underscoring the special requirements of a formal luxury chassis. Product details are not shown here, but the size itself signals a heavy-duty, prestige-oriented application where dimensions, load capability, and wheel compatibility all carry added importance. On a vehicle of this class, owners typically want both proper visual scale and suitable support, so exact verification of wheel and tire markings is advisable before selecting replacements.

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

750-16 is a large bias-ply size used on the 1956 Rolls Royce Silver Wraith. It has strong current product support, including Blackwall and Wide Whitewall choices from Firestone, Lester, and BFGoodrich. Several products list a 16-inch rim diameter, 5.00- to 6.00-inch wheel-width range, and maximum load capacities from roughly 1,660 to 1,850 pounds depending on the tire. This is a substantial fitment that suits a heavy formal car where both visual presence and load support matter. Buyers often compare sidewall style carefully here, since whitewall width can significantly influence the finished look of a Silver Wraith.

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

145R15 is a radial size associated with the 1956 Saab 92 & 93. Current offerings include Blackwall radials from Firestone and Michelin, plus a BFGoodrich Silvertown Radial Wide Whitewall option for those who want a more stylized vintage appearance. Some listed specifications include 3.50- to 5.00-inch rim-width compatibility and a maximum load capacity of 935 pounds at 44 psi on one Firestone product. This is a narrow, lightweight-car fitment where overall proportions matter as much as construction type. Owners should confirm wheel width carefully, especially on cars that may have received later replacement wheels.

5.20-15 is the bias-ply fitment associated with the 1956 Saab 92 & 93. It represents the traditional counterpart to the radial alternative used on this application, giving owners a choice between period-style construction and a radial approach where appropriate for the vehicle’s setup. Product details are not listed here, so the main focus should be on confirming exact size, wheel dimensions, and intended use. On compact Swedish cars of this era, tire size has a clear effect on stance and steering feel, making it especially important not to substitute loosely based on approximate dimensions.

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

560-14 is a bias-ply size associated with the 1956 Simca Aronde. Current products include BFGoodrich Blackwall, Narrow Whitewall, and Wide Whitewall options, giving buyers several appearance choices within a single vintage size. Listed specifications include a 14-inch rim diameter, 3.50- to 4.00-inch wheel-width range, and a published maximum load capacity of 906 pounds at 30 psi. This is a useful fitment for owners who want to maintain a period-style bias-ply profile on a compact French sedan. As with other small vintage sizes, exact wheel measurements help ensure the tire chosen matches the vehicle’s present configuration.
