The 2018 Aston Martin DB11 blends grand touring refinement with the long-hood, short-deck proportions that define Aston Martin’s modern flagship coupes. It is a high-speed road car meant to cover distance with composure, so tire fitment matters as much to balance and appearance as it does to grip. The 2018 Aston Martin DB11 uses a staggered radial setup with 255/40R20 up front and 295/35R20 at the rear on 20-inch wheels. Available choices center on modern blackwall performance tires from BFGoodrich and Nitto rather than vintage-style sidewall treatments. The key is matching the correct front and rear sizes while confirming the actual wheel setup on the car.
Which Tire Size Is Right for The 2018 Aston Martin DB11
The 2018 Aston Martin DB11 uses two primary tire sizes, and they serve different positions on the car rather than different trim levels. Both are radial tires on 20-inch rims, so the first step is confirming whether you are selecting a front or rear tire and making sure the wheel diameter and staggered setup on the car have not been changed.
255/40R20 is a modern metric radial size in which 255 identifies nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2018 Aston Martin DB11, this size is used at the front, where steering response and overall balance depend on keeping the proper front fitment in place. The available option in this size is a BFGoodrich blackwall tire from the g-Force Phenom T/A series. This is the size to evaluate when replacing worn front tires or confirming that the car still retains its intended staggered tire arrangement.
295/35R20 is a modern metric radial size with a 295-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2018 Aston Martin DB11, this is the rear tire size, giving the car the wider rear fitment that supports its staggered layout. The available option here is a Nitto blackwall tire in the NT555 G2 series, which gives the rear position a distinctly modern performance-tire character. This is the size to focus on when replacing rear tires and verifying that wheel width and rear clearance remain appropriate.
Sub-model fitment on the 2018 Aston Martin DB11 is straightforward, but the car uses different sizes at the front and rear. Checking the exact wheel position matters because the staggered setup requires matching the correct tire to each end of the vehicle.

2018 Aston Martin DB11 Base Front
The 2018 Aston Martin DB11 Base Front uses a 255/40R20 radial tire on a 20-inch wheel. Tire selection here centers on maintaining the correct front size and confirming wheel width if the car has been altered from its original staggered arrangement.
The 2018 Aston Martin DB11 Base Rear uses a 295/35R20 radial tire on a 20-inch wheel. Choosing the right rear tire means keeping the wider rear fitment in place and checking for proper clearance if aftermarket wheels or suspension changes are present.
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.
Best 2018 Aston Martin DB11 Tires for Sale
Available 2018 Aston Martin DB11 tire choices focus on modern radial blackwall performance tires in the correct staggered 20-inch sizes. The current options come from BFGoodrich and Nitto, with distinct tire series for the front and rear positions.
These FAQs focus on the staggered 20-inch tire setup used on the 2018 Aston Martin DB11, including front and rear sizing, rim fitment, product selection, and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2018 Aston Martin DB11?
The 2018 Aston Martin DB11 uses a staggered tire setup with 255/40R20 at the front and 295/35R20 at the rear. Both are radial tire sizes mounted on 20-inch wheels, so the car does not use the same size at all four corners.
That means tire selection starts with identifying wheel position, not just year, make, and model. A front replacement should stay with the front size, and a rear replacement should stay with the rear size unless the car has been deliberately reconfigured. It is also wise to confirm the actual wheels on the car if previous ownership included aftermarket changes.
What size rim does a 2018 Aston Martin DB11 use?
The 2018 Aston Martin DB11 uses 20-inch rims with both of its primary tire sizes. The front 255/40R20 and rear 295/35R20 are both built around the same 20-inch wheel diameter, even though the section widths and aspect ratios differ.
Matching rim diameter is only the first step, especially on a staggered grand touring car. Wheel width also matters, and any car fitted with aftermarket wheels should be checked carefully before replacement tires are chosen. Keeping the correct 20-inch diameter while verifying wheel width and clearance helps preserve the intended front-to-rear balance.
Why does the 2018 Aston Martin DB11 have more than one tire size?
The 2018 Aston Martin DB11 has more than one tire size because it uses a staggered setup. The front axle carries 255/40R20 tires, while the rear axle uses wider 295/35R20 tires, giving the car different tire dimensions at each end.
This matters because a staggered arrangement is part of the vehicle’s overall setup rather than a random size difference. Replacing only one pair of tires requires attention to position, construction, and wheel diameter so the front and rear remain matched to their intended roles. It is smart to inspect current wheel sizes and confirm that previous modifications have not altered the original layout.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Aston Martin DB11?
Start with the correct position-specific size: 255/40R20 for the front and 295/35R20 for the rear. From there, compare radial construction, wheel diameter, brand, tire series, sidewall style, and product specifications such as rim-width compatibility or load information where it is available.
The DB11 is not a one-size-fits-all application, so the right choice depends on whether you are replacing front tires, rear tires, or a complete set while preserving the staggered layout. A buyer should also consider how the car is used, whether the current wheels are original-size, and whether consistent appearance and handling matter more than mixing unlike tire types.
What brands offer tires for the 2018 Aston Martin DB11?
Current tire options for the 2018 Aston Martin DB11 include BFGoodrich and Nitto. BFGoodrich appears in the 255/40R20 front size with the g-Force Phenom T/A series, while Nitto appears in the 295/35R20 rear size with the NT555 G2 series.
Because the DB11 uses different front and rear sizes, brand choice may also be tied to tire position rather than simple preference. That makes it important to review each product in the correct size instead of assuming the same brand and series are available across the entire staggered setup. Matching the correct tire to each axle is the first priority.
What sidewall styles are available for 2018 Aston Martin DB11 tires?
The available tires for the 2018 Aston Martin DB11 use a blackwall sidewall style. That suits the DB11’s modern performance-touring character and keeps the visual presentation clean and contemporary rather than leaning toward vintage sidewall treatments.
Sidewall style is mostly an appearance decision once the correct front and rear sizes have been established, but it still affects the overall look of the car. On a vehicle like the DB11, the blackwall presentation aligns naturally with 20-inch radial performance tires. Buyers should still confirm that front and rear tires maintain a consistent visual and construction approach.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Aston Martin DB11?
Yes. Any change to wheels, suspension height, alignment settings, or body clearance can affect tire fitment on a 2018 Aston Martin DB11. That is especially important on a car with staggered 20-inch tires, because the front and rear sizes already differ as part of the normal setup.
A DB11 fitted with aftermarket wheels may no longer match original wheel widths or offsets, even if the rim diameter is still 20 inches. Lowering changes, spacer use, or bodywork modifications can also alter clearance during steering and suspension travel. Verifying the actual wheel and tire package on the car before ordering replacements helps avoid mismatch issues.
What should I inspect before driving a 2018 Aston Martin DB11 on new tires?
Check that the front tires are 255/40R20 and the rear tires are 295/35R20, and confirm that all four are properly mounted on 20-inch wheels. It is also wise to inspect inflation, wheel condition, valve stems, and overall tire seating before the first road use.
A visual inspection should also include tread and sidewall condition on any tire that has been stored, moved, or mounted recently. Look for cuts, bulges, irregular wear, or air loss, and make sure there is no interference at full steering lock or under suspension compression. A short shakedown drive followed by a recheck of pressure and clearance is a sensible final step.
How often should tires on a 2018 Aston Martin DB11 be inspected?
Tires on a 2018 Aston Martin DB11 should be inspected regularly rather than only when tread appears low. On a performance-oriented grand touring car with staggered fitment, routine checks for pressure, tread wear, sidewall condition, and visible damage help catch problems before they affect ride quality or stability.
Inspection matters even more if the car is driven seasonally or stored for stretches between outings. A low-use vehicle can still develop flat spotting, air loss, age-related cracking, or damage from impacts and road debris. Frequent visual checks and periodic professional inspections are a smart habit, particularly before highway trips or any longer-distance drive.
