1967 Aston Martin DB Tires

A 1967 Aston Martin DB uses two primary 15-inch tire sizes: 185R15 in radial construction and 775-15 in bias-ply construction. Both sizes belong to the fitment picture for this model, so the right starting point is not just size alone but also the type of tire construction the car is meant to use.

That distinction matters because the wheel diameter stays the same while the tire character changes. Owners typically narrow the choice by deciding whether they want a traditional bias-ply presentation or a radial setup, then confirming wheel width, sidewall preference, and overall clearance before settling on a specific tire.

The 1967 Aston Martin DB uses a 15-inch rim diameter with both of its primary tire sizes. That common rim diameter applies whether the car is fitted with a 185R15 radial or a 775-15 bias-ply tire, so the main fitment difference is construction rather than wheel diameter.

Rim diameter is only one part of the decision, though. It still helps to verify the actual wheel width on the car, especially if the vehicle has been restored, modified, or refitted with aftermarket wheels, because available tires in these sizes can call for different rim-width ranges within the same 15-inch diameter.

On a 1967 Aston Martin DB, 775-15 is a vintage numeric bias-ply tire size. The 7.75 portion refers to the tire’s nominal section width in inches, and the 15 refers to the wheel diameter in inches. It is a traditional bias-ply format rather than a modern metric radial designation.

That means a 775-15 should be understood as part of the car’s vintage tire presentation, with choices that often differ by sidewall style and brand rather than by modern aspect-ratio labeling. Anyone moving away from that size should compare the intended alternative carefully instead of assuming every 15-inch tire serves the same role.

For the 1967 Aston Martin DB, 775-15 is a bias-ply tire size. It is the traditional numeric bias-ply fitment, while 185R15 represents the radial side of the model’s 15-inch tire selection. The two sizes share rim diameter but differ in construction and in how they frame the car’s overall presentation.

That makes 775-15 the size to look at when a vintage-style setup is the priority. Owners comparing it to a radial should also review wheel width, sidewall appearance, and the car’s intended use, since changing construction can affect both the look of the car and the kind of tire choices available.

Radial equivalents for 775-15 include 195R15, P205/75R15, P215/70R15, and 670R15. In that group, 195R15 is an 80-series metric radial equivalent, P205/75R15 is a 75-series P-metric radial, P215/70R15 is a 70-series P-metric radial, and 670R15 is a bias-look radial equivalent.

These alternatives give different sizing conventions and visual directions rather than one automatic answer. The associated rim-width range is 5-7 inches, and any conversion should also be checked against the actual wheel, tire dimensions, and body or suspension clearance before treating one of these options as the right choice for the car.

A bias-look radial option is available for the 1967 Aston Martin DB through the 670R15 equivalent associated with the original 775-15 size. That makes it a useful choice for owners who want a radial alternative while still keeping a more traditional visual character than a more modern-looking metric or P-metric radial.

Even with that styling advantage, it should still be approached as an equivalent rather than an automatic replacement. The wheel should fall within the associated 5-7 inch rim-width range, and overall dimensions and clearance around the body and suspension should be confirmed before making the change.

Start with the car’s correct tire path: 185R15 radial or 775-15 bias-ply, both on 15-inch rims. From there, compare construction, sidewall style, tire series, brand, rim-width requirements, load figures where stated, and the visual character you want the car to carry on the road or at shows.

A road-driven grand touring car may lead an owner toward one kind of setup, while a restoration-oriented car may point toward another. It also helps to inspect the actual wheels on the car, since restored or modified vehicles do not always retain their original wheel specifications or tire priorities.

Sidewall choices for the 1967 Aston Martin DB include blackwall, redline, narrow whitewall, and goldline, along with more specialized presentations such as blue dot and raised white letter blue streak in the 775-15 bias-ply range. The 185R15 radial options include blackwall, redline, and narrow whitewall treatments.

That variety means sidewall style is an important part of choosing the right tire, especially on a car where visual balance matters. The smartest approach is to settle the correct size and construction first, then choose the sidewall treatment that suits the car’s restoration theme and the overall look of its wheels and body.

Tire options for the 1967 Aston Martin DB come from several brands, including Michelin, Avon, Coker Classic, Universal Vintage Tire, BFGoodrich, Firestone, and Goodyear. Brand availability depends on which primary size is being used, with radial choices centered around 185R15 and bias-ply selections centered around 775-15.

That brand spread is useful because it gives owners a broad mix of tire series and sidewall styles to compare without leaving the correct 15-inch fitment family. The better comparison point is not brand reputation alone, but how each tire matches the desired construction, appearance, wheel specification, and road-use plan.

For a period-style 1967 Aston Martin DB, the decision usually begins with whether the car should retain a 775-15 bias-ply look or use a 185R15 radial with a more road-oriented construction. Both paths can support a vintage presentation, but the bias-ply size carries the more traditional sizing format and broader period-style sidewall assortment.

The final choice depends on how closely the car is being restored and how it will be used. Owners seeking exact historical accuracy should compare the car’s details with marque references and restoration documentation, while those balancing appearance and driving use can focus on a tire that preserves the right visual scale and sidewall character.

Tire construction changes more than ride feel on a restored 1967 Aston Martin DB; it also affects how the car looks at a glance. A 775-15 bias-ply setup presents a traditional vintage format, while a 185R15 radial gives the car a different visual impression even when the wheel diameter remains at 15 inches.

That is why construction should be considered alongside sidewall treatment rather than after it. Redline, blackwall, narrow whitewall, and other available styles can all shift the car’s appearance, but the underlying bias-ply-versus-radial decision usually sets the tone for whether the finished result feels more traditional or more road-focused.

Yes, modifications can affect tire fitment on a 1967 Aston Martin DB even when the tire size appears correct on paper. Changes such as aftermarket wheels, altered wheel width, suspension work, lowering, or body repairs can all influence how a 185R15 or 775-15 tire sits in the wheel opening and clears nearby components.

That is why a modified car should be checked as it actually stands, not just by model-year fitment alone. Wheel diameter may remain 15 inches, but wheel width, offset, and available clearance can still change enough to influence which tire is the more practical choice for the finished setup.

Before driving a 1967 Aston Martin DB on new tires, inspect wheel condition, bead seating, valve stems, tire pressure, and basic clearance at the fenders and suspension. It is also smart to look over steering travel and confirm that the chosen tire size and construction match the actual wheel setup on the car.

Collector cars often sit for long periods, so a broader walkaround helps as well. Check for fluid leaks that could reach the tires, make sure lug hardware is secure, and verify there are no rubbing points once the car is on the ground and turned lock to lock before putting meaningful miles on it.

Tires on a collector 1967 Aston Martin DB should be maintained with regular pressure checks, periodic visual inspection, and careful storage habits. Look for cracking, cuts, bulges, unusual tread wear, and slow air loss, whether the car is on 185R15 radials or 775-15 bias-ply tires, because age can matter as much as mileage on a seldom-driven car.

Storage conditions make a real difference over time. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps protect the sidewalls, and moving or driving the car occasionally can help prevent long-term flat spotting from extended periods in one position.
