1956 Aston Martin Tire Fitment Guide

1956 Aston Martin vehicles in this guide use two tire sizes: 175R16 and 600-16. Both sizes apply to the 1956 Aston Martin Mark, and both are built around a 16-inch rim diameter. For 600-16 bias-ply products, the listed rim width range is 4.00 to 4.50 inches, which gives a useful reference point when checking an original wheel.

That means the first fitment question is simple: if you have a 1956 Aston Martin Mark, either listed size belongs in the conversation. The next step is deciding whether you want the traditional character of the numeric bias-ply size or the radial construction represented by 175R16, then confirming your wheel width and the exact sidewall style you want before moving further.

On a 1956 Aston Martin, 600-16 is a numeric bias-ply size. The 6.00 figure is the nominal section width in inches, and the 16 is the wheel diameter in inches. It is the older American and British-style size notation many mid-century cars used before metric radial sizing became common.

For an Aston Martin owner, that size usually points toward a more traditional visual and driving presentation. It is also the size with the broadest currently listed product variety here, including blackwall and wide whitewall versions, so it is often the place to start if your goal is period style or a restoration-minded appearance on a 16-inch wheel.

On a 1956 Aston Martin, 175R16 is a radial size with a nominal section width of 175 millimeters and a 16-inch rim diameter. The R identifies radial construction. Because no aspect ratio is written into the size, it follows the older Euro-metric convention commonly treated as an 80-series type rather than a modern low-profile fitment.

That matters because 175R16 is not just a different number for the same idea; it reflects a different construction approach from the 600-16 bias-ply size. Owners usually consider it when they want to stay with the original wheel diameter but prefer a radial-type setup for road use, steering feel, and overall touring behavior on a collector car.

For a 1956 Aston Martin Mark, the choice between 175R16 and 600-16 is primarily a construction decision because both use a 16-inch rim. The 600-16 size is the traditional numeric bias-ply option, while 175R16 is the radial option. That makes the comparison less about whether one size fits the model and more about how you want the car to look and behave.

Owners aiming for a restoration-focused presentation often gravitate toward the bias-ply route, especially when sidewall appearance matters. Owners who plan to spend more time driving the car on modern roads often look at the radial route first. Either way, confirm the actual wheel width and be sure the tire choice matches the way your Aston Martin will be shown, driven, and maintained.

The listed 600-16 tires for 1956 Aston Martin include both blackwall and wide whitewall sidewall styles. BFGoodrich and Firestone offerings appear in wide whitewall form, while Coker Classic and Avon are listed as blackwall products. That gives the Mark more than one visual direction within the same numeric bias-ply size.

For a British sports-touring car of this era, blackwall is usually the more understated and broadly authentic look, while whitewall options create a more stylized presentation. The right choice depends on how your particular car is being restored and the market style you want to evoke. Sidewall appearance can change the car’s overall impression almost as much as the construction choice itself.

The listed 600-16 tires for 1956 Aston Martin come from BFGoodrich, Coker Classic, Avon, and Firestone. All of those products are bias-ply offerings in the 16-inch numeric size. Avon is especially familiar in British performance and touring circles, while the other brands provide classic American-style reproduction options in the same basic fitment family.

Brand choice on a 1956 Aston Martin often comes down to the look you want, the specific sidewall treatment, and whether a particular product carries extra identifying details such as a speed symbol. Once you have settled on bias-ply versus radial, compare the individual products within that size for appearance and published specifications rather than choosing by brand name alone.

For 1956 Aston Martin bias-ply tires in size 600-16, the listed rim width range is 4.00 to 4.50 inches on a 16-inch diameter wheel. That is the only published rim-width range present here, and it gives a solid benchmark for evaluating original or restored wheels on the Mark.

Wheel diameter alone is not enough when fitting collector-car tires. Before finalizing a tire, measure or verify the actual wheel width and compare it to the specifications for the product you are considering. That step matters even more on older hand-built British cars, where wheel substitutions over the years are common and can affect both fitment and appearance.

Both listed tire sizes for the 1956 Aston Martin Mark are built for a 16-inch rim, so they share the same wheel diameter requirement. That means the original 16-inch wheels are the right starting point whether you are considering the 600-16 bias-ply size or the 175R16 radial size.

The remaining question is wheel width and overall wheel condition, not diameter. The published 600-16 range is 4.00 to 4.50 inches, and any original wheel should be checked carefully for width, straightness, corrosion, and past repairs before a new set goes on. Keeping the correct 16-inch wheel diameter simplifies the decision, but it does not replace a proper wheel inspection.

A 1956 Aston Martin should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, and other ozone-producing equipment that can age rubber prematurely. If the car sits for long periods, keep the tires properly inflated and either move the car periodically or support it in a way that reduces prolonged loading on one contact patch. Bias-ply tires are especially prone to temporary flat-spotting during static storage.

That storage routine protects both appearance and drivability when the car comes back out. Even a well-kept collector Aston Martin can develop vibration, sidewall checking, or uneven stress if it sits neglected on aging tires. A clean floor, stable temperature, and simple monthly attention do far more for tire life than many owners realize.

Tires on a 1956 Aston Martin should be judged primarily by age and condition rather than mileage. Collector-car tires often age out before they wear out, so a careful evaluation at around five to seven years is wise, and replacement becomes a serious consideration as tires approach ten years old. The DOT date code is the quickest way to establish the tire’s actual age.

That matters because a lightly driven Aston Martin can still be riding on old rubber that looks usable at a glance. Sidewall cracking, hardening, repeated air loss, and vibration are stronger warnings than tread depth on a low-mileage classic. If the car’s tires are already several years old, plan your inspection around age first and miles second.

Tires on a 1956 Aston Martin should be inspected before every drive and again before any longer trip. Look for sidewall cracking, tread separation, cuts, bulges, uneven wear, and pressure loss. If the car is fitted with older-style tires or wheels that have been off the road for years, include valve stems and the condition of the spare in the inspection routine.

Short local outings can hide tire issues that become obvious only after heat and speed build on the road. A minute of checking before departure is especially worthwhile on a mid-1950s grand-touring car, where chassis, brakes, and steering all depend on sound tires to deliver the car’s intended character and stability. Make tire inspection part of every pre-drive habit.

A 1956 Aston Martin Mark would originally have been associated with bias-ply tire practice, not modern radial fitment, because bias-ply construction was still standard across much of the industry in the mid-1950s. Within the sizes listed here, 600-16 is the period-style bias-ply option and aligns most closely with that era of fitment thinking.

Owners pursuing exact originality should still verify market-specific and body-specific details through Aston Martin clubs, factory literature, and recognized marque historians. Original fitment standards can vary by market and restoration target. Even when the general construction type is clear, judges and specialists may care about the exact size convention and the sidewall presentation used on the finished car.

Correct tire fitment matters on a shown 1956 Aston Martin because judges and knowledgeable enthusiasts notice size, construction, and sidewall style quickly. A mid-1950s Aston Martin presented for authenticity is more likely to be expected to wear a period-appropriate bias-ply type tire than a modern radial, and an eye-catching sidewall treatment can also affect how authentic the finished car appears.

That does not mean every show has the same standard. Some local events reward overall presentation, while concours-level judging may scrutinize tire details closely. If your car is being restored for formal judging, confirm the expected construction type and sidewall appearance with the rules of the event and with Aston Martin marque resources before making the final tire decision.

For the 1956 Aston Martin in 600-16, Avon Turbospeed and Coker Classic are both bias-ply options, but they differ in presentation and published details. Avon is listed as a blackwall 600H16 93H with a stated H speed rating, while Coker Classic is a blackwall 600-16 with a listed load capacity of 1400 pounds at 32 psi and a published rim-width range of 4.00 to 4.50 inches.

That makes the comparison less about one being universally right and more about what details matter for your car. If you want a product with a stated speed symbol in the size marking, Avon stands apart here. If you want a classic reproduction-style listing with clearly stated rim-width guidance, the Coker Classic details may be more useful for your wheel-fitment planning.

1956 Aston Martin tires can be suitable for highway driving when the tires are fresh, properly fitted, correctly inflated, and matched to the condition of the car. Among the listed 600-16 products, the Avon 600H16 93H carries an H rating, which corresponds to 130 mph, while the other bias-ply listings do not show a speed symbol in the size marking. Construction type still matters, because a radial and a bias-ply tire will feel different on the road even when both fit the same 16-inch wheel diameter.

Real-world safety in a mid-1950s Aston Martin also depends heavily on brakes, suspension, steering, alignment, and the age of every rubber component on the car. For most normal highway use, the condition of the car and the age of the tires will matter more than theoretical top-speed capability. Drive within the car’s mechanical limits and the tire manufacturer’s published ratings.

Inflation pressure for a 1956 Aston Martin should be tied to the exact tire chosen, not guessed from another size or construction. The listed 600-16 bias-ply products from BFGoodrich, Coker Classic, and Firestone show a maximum load of 1400 pounds at 32 psi. Avon’s 600H16 listing shows a maximum load of 1,433 pounds, but that figure should still be considered alongside the manufacturer’s guidance for the specific product.

Maximum pressure and load figures are not the same thing as the car’s recommended running pressure. For that, compare the car’s factory literature with the tire maker’s recommendations for the reproduction or specialty tire you are actually using. Keeping those sources separate is important on a classic Aston Martin, because switching from bias-ply to radial can change the pressure conversation.

Before a longer drive in a 1956 Aston Martin, inspect all four tires and the spare for cracks, bulges, cuts, unusual wear, and proper inflation. Check that the valve stems are sound, the wheels are secure, and the tires are not aged beyond reasonable service life. If the car has been sitting, look closely for flat-spotting or signs that the rubber has hardened with time.

Tires are only one part of a proper pre-trip inspection on a 1950s Aston Martin. Also review brake feel, steering play, wheel-bearing noise, fluid levels, and cooling-system condition before setting off. A grand-touring car from this era can cover distance beautifully when prepared correctly, but it rewards owners who treat tire condition as part of a full mechanical readiness check.
