1955 Aston Martin Tire Fitment Guide

1955 Aston Martin vehicles in this range use two tire sizes: 175R16 and 600-16, and both apply to the DB. Both sizes mount on 16-inch rims. For 600-16, available products show a rim width range of 4.00 to 4.50 inches, while the listed radial size remains a 16-inch fitment as well.

That means the first step is not identifying between multiple Aston Martin models for 1955, but deciding which construction you want on your DB. If your priority is preserving a distinctly mid-1950s appearance and feel, the bias-ply option will usually be the natural starting point. If you prefer a more modern driving character while keeping the same basic wheel diameter, the radial size is the one to investigate next.

On a 1955 Aston Martin, 600-16 is a traditional numeric tire size used with bias-ply construction. The "600" identifies the nominal section width class, and the "16" is the wheel diameter in inches. For the DB, this size appears in classic bias-ply offerings from BFGoodrich, Coker Classic, Avon, and Firestone.

Modern buyers often encounter this size while restoring a car from the 1940s and 1950s, when numeric bias-ply sizing was standard practice. On a DB, choosing 600-16 usually means you are leaning toward an authentic visual profile and an era-correct tire type. It is also worth checking sidewall style carefully, because this size is available in both blackwall and wide whitewall versions, which can change the finished look significantly.

On a 1955 Aston Martin, 175R16 is a radial metric-style size. The "175" refers to a nominal section width of 175 millimeters, the "R" denotes radial construction, and the "16" is the wheel diameter in inches. For the DB, it serves as the radial alternative to the older 600-16 bias-ply size.

That difference matters because the code signals a different construction philosophy, not just a different number on the sidewall. A radial fitment is often chosen by owners who intend to drive their DB more regularly and want a tire that behaves more like a later-period road tire. Even so, the wheel still needs to be checked carefully, since keeping the same rim diameter does not automatically answer every wheel-width or clearance question.

For a 1955 Aston Martin DB, the real difference between 175R16 and 600-16 is construction as much as size format. The 600-16 is the classic bias-ply choice associated with the period, while 175R16 is the radial alternative on the same 16-inch wheel diameter. Each can suit the DB, but they represent two distinct ownership priorities.

Owners focused on restoration character, period presentation, and the steering feel typical of a mid-1950s car often start with 600-16. Owners who plan to use the car more regularly on modern roads may prefer to investigate the radial route. The best approach is to decide early whether authenticity or updated road behavior matters more for your particular DB, then verify that the wheel itself matches the chosen tire's requirements.

For 1955 Aston Martin fitments in 600-16, available sidewall styles include blackwall and wide whitewall. BFGoodrich and Firestone offer wide whitewall versions in this size, while Coker Classic and Avon are offered as blackwalls. That gives DB owners more than one visual direction even within the same bias-ply size.

A blackwall tire is generally the more restrained and sporting look for a British grand touring car of this era, while a wide whitewall creates a more stylized presentation. Either can fit the wheel size, but the right choice depends on how authentic you want the finished car to appear for your market, body style, and restoration goal. If show accuracy matters, compare your choice against period photos and marque-club guidance before committing.

The 600-16 fitment for 1955 Aston Martin vehicles is available from BFGoodrich, Coker Classic, Avon, and Firestone. Those options span both blackwall and wide whitewall styles within the same basic bias-ply size. The DB's radial fitment is handled separately under 175R16.

Brand choice often comes down to the visual effect you want and the exact product specifications tied to the individual tire. Avon, for example, appears here in an H-rated 600H16 format, while BFGoodrich and Firestone offer whitewall presentations that change the car's appearance immediately. Rather than treating the brand name alone as the deciding factor, compare the exact size marking, sidewall style, and any speed-rating details that matter for how you use the car.

For 1955 Aston Martin fitments in 600-16, the listed rim width range is 4.00 to 4.50 inches on a 16-inch rim. That range applies to the bias-ply products in this size from BFGoodrich, Coker Classic, and Firestone. The DB's 175R16 option also uses a 16-inch rim diameter.

Rim width matters because a tire can share the correct wheel diameter and still be poorly matched to the wheel itself. Before finalizing a tire for a DB, measure the wheel and compare it to the requirement for the exact product you plan to use. That is especially important on older British cars, where wheel changes over the decades are common and previous owners may have fitted something different from the original arrangement.

A 1955 Aston Martin DB uses two listed tire sizes, 175R16 and 600-16, and both are built around a 16-inch wheel diameter. That means the original wheel diameter is consistent across both fitments. The 600-16 products with published specifications call for a 4.00 to 4.50 inch rim width.

In practical terms, that makes wheel-diameter compatibility straightforward, but you should still confirm the exact wheel width before moving between a bias-ply and radial option. A DB that has been restored, modified, or refitted over the years may no longer have the wheel it left the factory with. Verifying the wheel itself is the best way to avoid choosing a tire that is correct in diameter but not ideal in overall wheel fit.

A 1955 Aston Martin should be stored in a cool, dry, dark environment away from direct sunlight, electric motors, battery chargers, and other ozone-producing sources that can age rubber more quickly. If the car sits for long periods, keep the tires properly inflated and move the car periodically or support it appropriately to reduce prolonged flat-spotting. Bias-ply tires are especially prone to developing temporary flat spots during long static storage.

That matters on a DB because collector cars often spend far more time parked than driven, and storage habits influence tire condition as much as mileage does. Clean, dry flooring and a breathable cover help the car overall, but the tires need their own routine as well. If your Aston Martin alternates between seasonal use and long layups, check pressures before and after storage and inspect the sidewalls closely before returning it to regular driving.

On a 1955 Aston Martin, tire life is usually governed more by age than by miles traveled. A sensible rule is to begin evaluating collector-car tires closely at around five to seven years of service and to treat ten years as the point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the tire is the starting point for that timeline.

A DB that covers only limited annual mileage can still age out a set of tires simply through time, heat cycles, and storage conditions. Tread depth alone does not tell the full story on a low-use grand tourer. If the car spends long periods parked, the rubber can harden and the casing can age even when the tires still look presentable at a glance, so replacement planning should be calendar-based rather than mileage-based.

Tires on a 1955 Aston Martin should be inspected before every drive and again before any longer outing. Look for cracking in the sidewall, cuts, bulges, irregular wear, signs of impact damage, and any loss of pressure between drives. Valve stems should also be checked closely, especially on a car that is driven only occasionally.

A quick pre-drive inspection is one of the easiest ways to protect a DB from a preventable roadside problem. Vintage cars often go from sitting still to covering meaningful distance in one trip, and that puts extra importance on pressure retention and visible condition. Make the spare part of the same routine, because an aged or neglected spare is of little use if you need it on a tour or club drive.

A 1955 Aston Martin DB would originally have belonged to the bias-ply era, and the 600-16 size aligns with that period construction. Radial fitments such as 175R16 represent a later-style alternative rather than the default mid-1950s presentation. No single original equipment brand should be assumed without checking period factory literature and market-specific references.

For restoration work, that usually means starting with 600-16 if your goal is to reproduce the character the car had when new. The finer points can still vary by destination market, body style, and owner preference over the decades, so a marque club or Aston Martin specialist is the right place to confirm what is most appropriate for your exact DB. That extra step is especially worthwhile before concours judging or a historically sensitive restoration.

Correct tire fitment matters on a 1955 Aston Martin because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall presentation immediately. On a DB, a bias-ply 600-16 is generally more in keeping with period expectations than a radial fitment if the car is being judged for originality. Sidewall style can also affect how authentic the finished car appears.

A modern radial may be a sensible driving choice, but it can stand out on a car restored to factory-era presentation. The same is true of a sidewall treatment that does not suit the car's intended market or restoration theme. If your Aston Martin will be shown, review the event's judging standards and compare your planned tire choice against period photos, club guidance, and the restoration philosophy you are trying to maintain.

For a 1955 Aston Martin DB in 600-16, Avon Turbospeed and Coker Classic differ in both presentation and specification. The Avon appears as a blackwall 600H16 93H with a stated H speed rating, while the Coker Classic is a blackwall 600-16 bias-ply listed with a 1400-pound maximum load at 32 psi and a 4.00 to 4.50 inch rim width range. Both are bias-ply choices, but they are not identical in sidewall marking or published detail.

That makes the comparison less about one being universally preferable and more about which one suits your intended use and restoration priorities. An owner who wants a classic blackwall look with a clearly stated speed rating may focus on the Avon, while another may prefer the more straightforward traditional specification format of the Coker Classic. Matching the tire's visual style and technical marking to the car's mission is the smarter approach than choosing by name alone.

1955 Aston Martin tires can be suitable for highway driving when they are the correct size, in sound condition, and used within the limits of their construction and speed rating. Among the listed 600-16 products, the Avon 600H16 carries an H rating, which corresponds to a 130 mph ceiling. The broader question on a DB is often less about headline tire speed than the condition of the car's brakes, steering, suspension, and age-sensitive components.

A mid-1950s Aston Martin is capable and rewarding on the road, but highway confidence comes from the whole vehicle working properly, not from the tire alone. Before any sustained road use, inspect the tires carefully, confirm inflation, and make sure the car itself is properly sorted. If the DB is used mostly for touring rather than show presentation, construction choice also matters because bias-ply and radial tires deliver very different road feel.

Inflation pressure for a 1955 Aston Martin should be set by matching the car's factory guidance with the exact tire's published limits. In the available 600-16 products, several bias-ply tires are listed at 1400 pounds maximum load at 32 psi. That figure belongs to those specific products and should not be transferred automatically to every tire or to the 175R16 radial alternative.

For a DB, the right process is to start with the owner's manual or marque literature for the vehicle's intended operating pressure, then confirm that your chosen reproduction tire is being used within its rated specifications. Pressure has a direct effect on wear, ride quality, and stability, especially on an older grand tourer. If you change construction type from bias-ply to radial, revisit the recommendation rather than assuming the old setting still applies unchanged.

Before a longer drive in a 1955 Aston Martin, inspect every tire for sidewall cracking, cuts, bulges, uneven wear, and pressure loss. Check the spare as carefully as the four road tires, and make sure the valve stems are sound. If the car has been stored for a while, pay extra attention to flat-spotting and age-related hardening before setting off.

That tire inspection should be part of a broader pre-drive routine suited to a hand-built 1950s GT car. Verify wheel security, steering feel, brake operation, fluid levels, and basic lighting before committing to a longer run. A DB can cover distance beautifully when properly prepared, but age and low-use patterns mean small issues often surface only when the car is asked to do more than a short local outing.
