The 2021 Aston Martin DBS sits at the sharp end of the modern grand touring world, combining long-hood Aston Martin proportions with the kind of power and speed that demand serious tire fitment. Whether the car is a DBS Superleggera coupe or the open-top Volante, tire selection is tied to a staggered 21-inch setup rather than a one-size-fits-all arrangement. The front uses 265/35R21 radial tires, while the rear uses 305/30R21 radials. That makes this page less about choosing between vintage-style constructions and more about matching the correct front and rear sizes, preserving the intended stance, and confirming wheel and clearance details before replacement.
Which Tire Size Is Right for The 2021 Aston Martin DBS
The 2021 Aston Martin DBS uses two primary tire sizes, both in radial construction on 21-inch rims. The key detail is that these sizes are position-specific rather than interchangeable, with one size used at the front and the other at the rear across the DBS Superleggera and DBS Superleggera Volante. Before choosing a tire, confirm whether you are replacing a front or rear tire and verify that the car still has its correct staggered wheel setup.
Fit(s): Superleggera Front and Superleggera Volante Front
Construction: Radial|Rim: 21 in
265/35R21 is a modern metric radial size in which 265 indicates nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 21 is the rim diameter in inches. On the 2021 Aston Martin DBS, this size is used at the front, where precise steering response and correct front-end fitment matter. Its relatively short sidewall is part of the car's modern performance-oriented tire profile. Choosing this size means confirming that the front wheel remains a 21-inch application and that no wheel, suspension, or alignment changes have altered front clearance requirements.
Fit(s): Superleggera Rear and Superleggera Volante Rear
Construction: Radial|Rim: 21 in
305/30R21 is also a modern metric radial size, with 305 representing nominal section width in millimeters, 30 showing a lower-profile sidewall, and 21 identifying the wheel diameter. On the 2021 Aston Martin DBS, this is the rear tire size and forms the wider half of the car's staggered setup. That rear fitment supports the DBS's high-performance grand touring character and should be treated as a dedicated rear application rather than a general alternative. Selecting this size starts with confirming the rear wheel position and making sure the car has not been modified in a way that changes clearance or wheel specification.
Sub-model fitment on the 2021 Aston Martin DBS is straightforward in size but important by axle position. Both the DBS Superleggera and DBS Superleggera Volante use the same staggered arrangement, so the main task is matching the correct front or rear tire rather than sorting through different trim-specific tire packages.

2021 Aston Martin DBS Superleggera Front
The DBS Superleggera front fitment uses the smaller of the two staggered radial sizes on a 21-inch rim. Tire selection here should focus on preserving correct front fitment and ensuring the replacement matches the car's intended front axle position.
The DBS Superleggera rear fitment uses the wider 21-inch radial size that completes the staggered setup. Rear tire selection should center on maintaining the proper rear specification and checking that wheel or suspension changes have not affected available clearance.
The DBS Superleggera Volante front uses the same front radial size as the coupe on a 21-inch wheel. That keeps replacement straightforward, provided the tire is matched to the front position and the car still carries its intended wheel setup.
The DBS Superleggera Volante rear uses the same wider rear radial size as the coupe. Choosing a rear replacement means keeping the staggered arrangement intact and confirming that the actual rear wheel and suspension setup remains consistent with that fitment.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Tire questions for a 2021 Aston Martin DBS usually come down to staggered sizing, front-versus-rear fitment, 21-inch wheel confirmation, and the practical checks to make before replacing tires on a high-performance grand touring car.
Tire Size & Fitment
What tire size fits a 2021 Aston Martin DBS?
The 2021 Aston Martin DBS uses a staggered tire setup with 265/35R21 at the front and 305/30R21 at the rear. Both sizes are radial tires mounted on 21-inch wheels, and they are tied to axle position rather than being interchangeable choices for all four corners.
That means the first step is identifying whether you need a front or rear tire. A staggered setup affects appearance, clearance, and the car's intended balance, so replacement should start with the actual wheel position and the current wheel specification on the car.
What size rim does a 2021 Aston Martin DBS use?
Both primary tire sizes for the 2021 Aston Martin DBS fit 21-inch rims. The front 265/35R21 and rear 305/30R21 share the same rim diameter, even though the rear tire is substantially wider and uses a lower aspect-ratio sidewall.
Confirming rim diameter is still worth doing before replacement, especially on a modified or second-owner car. A 21-inch tire size must be matched to a 21-inch wheel, and the actual wheel width and overall setup should also be checked before mounting new tires.
Do all 2021 Aston Martin DBS sub-models use the same tire size?
The covered 2021 Aston Martin DBS sub-models share the same staggered sizing pattern. Both the DBS Superleggera and DBS Superleggera Volante use 265/35R21 at the front and 305/30R21 at the rear, so the difference is position on the car rather than coupe-versus-convertible sizing.
That keeps fitment relatively simple, but it does not make front and rear tires interchangeable. Anyone replacing tires should still confirm axle position, wheel fitment, and whether the car has had aftermarket wheel, suspension, or alignment changes that could affect clearances.
Choosing the Right Tire
What should I consider when choosing 2021 Aston Martin DBS tires?
Start with the correct axle-specific size: 265/35R21 for the front and 305/30R21 for the rear. Because the 2021 Aston Martin DBS uses a staggered radial setup, the main selection factors are correct position, 21-inch rim compatibility, and keeping the intended front-to-rear tire relationship intact.
After that, look at the actual wheel setup on the car and how it is used. A DBS that remains stock presents a different fitment picture than one with aftermarket wheels, alignment changes, or altered ride height, so those details should be verified before choosing replacements.
How do I choose between the available 265/35R21 and 305/30R21 tires for a 2021 Aston Martin DBS?
The choice begins with location, not preference. The 265/35R21 size belongs on the front of the 2021 Aston Martin DBS, while the 305/30R21 size belongs on the rear, so selection is built around maintaining the car's staggered radial fitment.
Once the correct position is confirmed, compare the actual wheel specification and the tire's intended use on the vehicle. Matching the right size to the right axle helps preserve fitment, while checking wheel width, suspension condition, and available clearance helps avoid problems during installation.
What rim-fitment details matter when choosing tires for a 2021 Aston Martin DBS?
The most important rim-fitment detail is that both primary sizes are built for 21-inch wheels. Even with a shared rim diameter, the front and rear tires differ in width and profile, so the car's wheel setup must still match the tire position you are replacing.
A second check is whether the car still has its original wheel layout or has moved to an aftermarket setup. Wheel width, offset, and ride-height changes can alter clearance at the fender, suspension, or steering components, even when the nominal tire size appears correct.
Restoration & Appearance
Does correct tire fitment matter for a 2021 Aston Martin DBS restoration or preservation-focused car?
Yes. Even on a modern collector-grade car like the 2021 Aston Martin DBS, correct tire fitment plays a major role in preserving the car's stance, wheel-to-tire proportions, and intended front-to-rear visual balance. The staggered 265/35R21 front and 305/30R21 rear setup is part of that presentation.
A preservation-minded replacement should begin with the correct sizes and the actual wheel setup currently on the car. Owners seeking exact historical accuracy should also compare replacement choices with marque-specific references and vehicle history records rather than relying on size alone.
How does tire sizing affect the appearance of a 2021 Aston Martin DBS?
Tire sizing has a visible effect on the 2021 Aston Martin DBS because the car uses a staggered arrangement with a narrower front and wider rear. That difference contributes to the planted, modern grand touring look of the car and helps define how the 21-inch wheels visually fill the body.
Changing away from the established front and rear sizes can alter that balance even before any handling differences are considered. Anyone focused on appearance should confirm both axle sizes carefully and avoid assuming that a same-diameter wheel automatically means front and rear tire sizes can be mixed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Aston Martin DBS?
Yes. A 2021 Aston Martin DBS that has aftermarket wheels, altered suspension height, alignment changes, or body modifications may need closer fitment review even if it still appears to use the original 265/35R21 front and 305/30R21 rear sizes. Clearance can change without changing the size code.
That is why replacement should include a check of actual wheel diameter, wheel width, and available space at the fender and suspension. A staggered high-performance setup leaves less room for guesswork, so any modified car deserves a position-by-position inspection before mounting new tires.
What should I inspect before driving a 2021 Aston Martin DBS on new tires?
Before road use, inspect tire pressure, mounting direction where applicable, bead seating, valve condition, and visible clearance at the suspension and fender edges. On a 2021 Aston Martin DBS, it also makes sense to confirm that the 265/35R21 tires are on the front and the 305/30R21 tires are on the rear.
A short initial check drive is useful for catching vibration, rubbing, or pressure loss early. After that, recheck inflation and look again for any contact marks, especially if the car has nonstandard wheels, lowered suspension, or other changes that could narrow available clearance.
How often should tires on a 2021 Aston Martin DBS be inspected?
Tires on a 2021 Aston Martin DBS should be inspected regularly, not just when tread appears low. Performance-oriented low-profile tires can show wear, impact damage, or air-loss issues that are easier to catch early, particularly on a car that sees spirited driving or long periods of storage.
A practical routine is to check pressure and visible condition before drives, then make fuller inspections for tread wear, cuts, bulges, and cracking on a regular schedule. Collector cars that sit for extended periods also benefit from clean storage conditions and periodic movement to avoid long static loading.
