The 1971 Aston Martin DB sits at the refined end of the grand touring world, where hand-built British character and long-distance road manners mattered as much as outright speed. On a car with that kind of presence, tire choice affects stance, period appearance, and the way the car feels on the road. The 1971 Aston Martin DB uses bias-ply fitments in 8.25-15 and 815-15 on 15-inch rims. Within those sizes, the available choices lean toward traditional presentation, including narrow whitewall and whitewall-redline styles in BFGoodrich's Silvertown Classic Bias Ply series. For a restoration-oriented owner, the main task is confirming the exact size on the car now and matching the tire's look and construction to the car's intended use.
Which Tire Size Is Right for The 1971 Aston Martin DB
The 1971 Aston Martin DB uses two primary tire sizes, and both are bias-ply fitments for 15-inch rims. Because these sizes are associated with the same covered sub-model, the key step is confirming which size is already on the car and then choosing the sidewall style and product presentation that best suits your restoration goals and road use.
In the 8.25-15 size format, the first number refers to the tire's nominal section width in inches, while the final number identifies the 15-inch rim diameter. This is a bias-ply fitment, which suits the traditional construction style associated with a 1971 Aston Martin DB. Bias-ply tires are often chosen to preserve a period-style look and the visual proportions expected on a hand-built grand touring car of this era. If your DB is already set up around 8.25-15, the priority is confirming wheel and vehicle setup before selecting a tire with the appearance and construction that matches your goals.
The 815-15 designation is also a numeric bias-ply size, with the leading number expressing nominal section width and the final number indicating a 15-inch rim. On the 1971 Aston Martin DB, this size supports a distinctly vintage tire presentation and remains closely tied to restoration-minded selection. Available 815-15 products include BFGoodrich options in the Silvertown Classic Bias Ply series, with Narrow Whitewall and Whitewall-Redline sidewall treatments. That makes 815-15 especially useful for owners who want to stay with bias-ply construction while tailoring the finished look of the car.
Fitment is straightforward here because the covered sub-model uses the same pair of primary bias-ply sizes. Even so, checking the exact sub-model and the tire size already mounted on the car helps keep wheel compatibility and restoration appearance aligned.

Owners of a 1971 Aston Martin DB usually want clarity on the correct bias-ply size, 15-inch rim fitment, sidewall appearance, and what to inspect before putting a collector car back on the road. These FAQs focus on those practical tire-selection and road-use decisions.
Tire Size & Fitment
What tire size fits a 1971 Aston Martin DB?
The 1971 Aston Martin DB uses two primary tire sizes: 8.25-15 and 815-15. Both are bias-ply sizes for 15-inch rims, and both are associated with the covered 1971 Aston Martin DB 6 Mark II fitment.
The practical next step is to confirm which size is actually on the car now, especially on a collector vehicle that may have seen earlier wheel or tire changes. Checking the sidewall marking, wheel diameter, and overall clearance before ordering helps keep the replacement aligned with the car's current setup and intended appearance.
What size rim does a 1971 Aston Martin DB use?
The primary tire fitments for a 1971 Aston Martin DB are built around a 15-inch rim diameter. Both 8.25-15 and 815-15 use that same rim diameter, so the wheel diameter remains consistent across the covered fitments.
Rim diameter is only part of the picture on a vintage car. Wheel width also matters, along with the actual tire size already mounted and any past changes to wheels or suspension. Taking a moment to confirm the current wheel setup helps avoid choosing a tire that matches the diameter but not the rest of the car's fitment needs.
Does the 1971 Aston Martin DB 6 Mark II use the same tire size?
The covered 1971 Aston Martin DB 6 Mark II uses the same two primary tire sizes associated with this vehicle page: 8.25-15 and 815-15. Both are bias-ply fitments and both use a 15-inch rim diameter.
That makes sub-model identification less complicated than on vehicles with trim-specific tire packages, but the owner still needs to verify which size is on the car. Many collector cars have gone through decades of tire replacement, so reading the existing sidewall and checking wheel dimensions remains the safest way to stay on the right fitment path.
Choosing the Right Tire
What should I consider when choosing a 815-15 tire for a 1971 Aston Martin DB?
A 815-15 tire for a 1971 Aston Martin DB should first match the car's primary size, bias-ply construction, and 15-inch wheel diameter. From there, the choice comes down to details such as sidewall treatment, the tire series, and whether the wheel width falls within the product's stated compatibility range.
For the available 815-15 options, appearance is a major part of the decision because the sidewall changes the car's visual character. It also helps to compare load capacity and confirm that the car has not been altered with different wheels. That approach keeps the tire choice grounded in both fitment and the finished look of the car.
What sidewall styles are available for 1971 Aston Martin DB tires?
Within the available 815-15 product choices for a 1971 Aston Martin DB, sidewall styles include Narrow Whitewall and Whitewall-Redline. Both options retain a traditional bias-ply presentation, but they give the car distinctly different visual accents once mounted.
That decision is mainly about appearance rather than basic fitment, since the available options share the same size and construction type. A narrow whitewall tends to keep the look understated, while a whitewall-redline combination adds more visual emphasis. Matching the sidewall style to the car's restoration direction usually matters as much as choosing the correct size.
What brands offer tires for the 1971 Aston Martin DB?
The available product fitment shown here for the 1971 Aston Martin DB comes from BFGoodrich in the 815-15 size. Those products are part of the Silvertown Classic Bias Ply series and stay within the traditional bias-ply construction used on this vehicle.
Since the product variety centers on one brand in this fitment, the more useful comparison is between sidewall styles and wheel-width compatibility rather than brand-to-brand differences. Owners should also keep the second primary size, 8.25-15, in mind and confirm the exact size on the car before narrowing the choice to a specific tire style.
Restoration & Appearance
Which tire should I choose for a period-style 1971 Aston Martin DB?
A period-style approach for a 1971 Aston Martin DB starts with the primary bias-ply sizes used on the car, 8.25-15 or 815-15, depending on the setup being matched. Staying with bias-ply construction preserves the traditional visual character and sizing language associated with this early-1970s grand touring Aston Martin.
The final decision often comes down to how closely the owner wants to mirror a vintage presentation versus simply keeping the right general era and stance. When exact originality matters, it is wise to compare the car against marque references, historic photos, or restoration records, then choose the sidewall treatment that supports that goal.
How does tire construction affect the appearance of a restored 1971 Aston Martin DB?
Tire construction changes more than ride feel on a restored 1971 Aston Martin DB; it also influences the car's visual proportions and overall presentation. A bias-ply tire keeps the vintage construction style associated with the car's primary fitments and generally supports a more traditional collector-car look.
That matters because a restoration is judged as much by stance and detail as by paint and trim. Even when the size is correct, a different construction can change the way the tire visually complements the wheel opening and side profile. Owners focused on authenticity usually treat construction as part of the car's finished appearance, not just a mechanical choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 Aston Martin DB?
Yes, modifications can affect tire fitment on a 1971 Aston Martin DB even when the tire size appears correct on paper. Changes such as aftermarket wheels, different wheel widths, altered suspension height, or body and brake updates can all influence clearance and how a bias-ply tire sits on the car.
That is why a collector vehicle should be checked as it exists today, not only by its original fitment pattern. Measuring wheel diameter and width, then checking steering movement and fender clearance, helps prevent surprises. On an older grand touring car, small setup changes can make a noticeable difference in real-world fitment.
What should I inspect before driving a 1971 Aston Martin DB on new tires?
Before driving a 1971 Aston Martin DB on new tires, inspect the wheels, valve stems, and mounting surfaces, then confirm the tires are correctly seated and inflated. It is also smart to look over suspension and steering components, since worn parts can affect how a vintage bias-ply tire tracks and wears.
A careful walkaround after installation helps catch problems early. Look for rubbing marks, uneven clearance, cuts, bulges, or any sign of air loss once the car has settled on the tires. On a collector car that may sit for long periods, a short test drive followed by a second inspection is a sensible final check.
How should 815-15 tires on a collector 1971 Aston Martin DB be maintained?
815-15 tires on a collector 1971 Aston Martin DB should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Even if tread wear is low, bias-ply tires on a seldom-driven car can still develop cracking, flat spotting, or deterioration from long storage.
Storage conditions matter almost as much as mileage on a classic Aston Martin. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps protect the sidewalls, while periodic movement can reduce long-term stress in one contact area. Routine checks before each drive are especially important on a vintage car that is not used daily.
