In 2023, Aston Martin balanced grand touring elegance with serious modern performance, offering a range that stretched from the refined DB11 to the harder-edged Vantage and the flagship DBS. Every model carried low-profile radial fitments, but the year did not use one universal size across the lineup. DB11 and Vantage share several front and rear sizes in both 20- and 21-inch fitments, while DBS uses its own 21-inch staggered combination and Vantage also adds a wider 21-inch setup of its own. For a 2023 Aston Martin, the first step is confirming the exact model and whether your car is on its 20-inch or 21-inch wheel package before choosing tires.
Which Tire Size Is Right for Your 2023 Aston Martin
Eight tire sizes appear across the 2023 Aston Martin range, and they vary by model rather than carrying across every car in the lineup. The real decision starts with confirming the correct model and wheel diameter, since some fitments are 20-inch and others are 21-inch, with staggered front and rear sizing throughout the range. Understanding that distinction before choosing a product saves time and helps ensure the right match.
255/35R21 is a metric radial size with a 255-millimeter section width, a 35-series aspect ratio, and a 21-inch rim diameter. It fits DB11 and Vantage applications rather than the full 2023 Aston Martin range, but no products are currently represented here to compare brands, sidewall styles, tube status, or speed ratings within this size. This is a model-specific 21-inch fitment to confirm against the actual front or rear wheel on the car before moving to a tire choice.
Year(s): 2023|Fit(s): DB11, Vantage|Construction: Radial|Rim: 20 in
255/40R20 is a metric radial size with a 255-millimeter section width, a 40-series aspect ratio, and a 20-inch rim diameter. BFGoodrich offers this size in a Blackwall configuration, and the available example carries a Y speed rating with a 186-mph ceiling and a load rating of 1,819 pounds at 50 psi. This shared DB11 and Vantage size suits owners confirming a 20-inch fitment and looking for a modern radial tire in a contemporary performance style.
295/30R21 is a metric radial size with a 295-millimeter section width, a 30-series aspect ratio, and a 21-inch rim diameter. It is used on DB11 and Vantage rather than across all 2023 Aston Martin models, though no products are currently represented here to compare brands, sidewall styles, tube status, or speed ratings within the size. Buyers should treat it as a shared 21-inch model-specific fitment and confirm whether it belongs on the front or rear axle of their exact car.
Year(s): 2023|Fit(s): DB11, Vantage|Construction: Radial|Rim: 20 in
295/35R20 is a metric radial size with a 295-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. Nitto offers this size in a Blackwall configuration, and the available example carries a W speed rating with a 168-mph ceiling. This shared DB11 and Vantage fitment is the companion 20-inch wide size and should be matched to the correct axle position before selecting a tire.
265/35R21 is a metric radial size with a 265-millimeter section width, a 35-series aspect ratio, and a 21-inch rim diameter. It is specific to the DBS within the 2023 Aston Martin range, and no products are currently represented here to compare brands, sidewall styles, tube status, or speed ratings within this size. DBS owners should start by confirming this dedicated 21-inch fitment rather than assuming interchange with DB11 or Vantage sizes.
305/30R21 is a metric radial size with a 305-millimeter section width, a 30-series aspect ratio, and a 21-inch rim diameter. It is also specific to the DBS, with no products currently represented here to compare brands, sidewall styles, tube status, or speed ratings across this size. As the wider DBS 21-inch fitment, it should be verified carefully against the car's exact wheel position before choosing a tire.
275/35R21 is a metric radial size with a 275-millimeter section width, a 35-series aspect ratio, and a 21-inch rim diameter. This size is specific to certain Vantage fitments rather than universal across the 2023 Aston Martin range, and no products are currently represented here to compare brands, sidewall styles, tube status, or speed ratings within the size. Vantage owners should confirm this dedicated 21-inch application before treating it as interchangeable with the DB11 or DBS front size.
315/30R21 is a metric radial size with a 315-millimeter section width, a 30-series aspect ratio, and a 21-inch rim diameter. It is specific to Vantage applications and no products are currently represented here to compare brands, sidewall styles, tube status, or speed ratings within this size. This is the widest 2023 Aston Martin size in the range, so confirming the exact Vantage wheel package is essential before selecting a tire.
Three Aston Martin models are covered for 2023, and they do not all use the same tire sizes. DB11 and Vantage overlap in several staggered front and rear fitments, while DBS uses its own dedicated 21-inch combination and Vantage adds an additional wider 21-inch setup of its own. Select your model below to narrow the fitment history and see the tire options that apply to that specific car.
2023 Aston Martin DB11
The DB11 is Aston Martin's grand touring coupe, blending high-speed refinement with a more luxurious character than the brand's sharper sports-car offerings. Its fitments span both 20-inch and 21-inch wheels, so wheel diameter is the first thing to verify before moving to front and rear tire selection.
The DBS sits at the top of Aston Martin's front-engine performance line, with a more forceful personality and a dedicated fitment package of its own. Its tires mount on 21-inch wheels, using a staggered front and rear setup that does not overlap with the DBS model's siblings in the same way as the DB11 and Vantage pairings do.
The Vantage is Aston Martin's focused sports car, with a shorter-wheelbase, more aggressive feel than the DB11 grand tourer. It uses both 20-inch and 21-inch wheel fitments depending on application, including several sizes shared with DB11 and an additional wider 21-inch combination unique to Vantage.
Two products are available across two tire sizes for 2023 Aston Martin vehicles. The 255/40R20 has one BFGoodrich radial Blackwall option, and the 295/35R20 has one Nitto radial Blackwall option. Confirm your exact size first, since speed ratings differ between these fitments.
These FAQs sort out the 20- and 21-inch fitments used across the 2023 Aston Martin range, explain how DB11, DBS, and Vantage sizes differ, and cover practical details such as sidewall style, load and speed ratings, setup, and long-term care.
Size Basics & Fitment
What tire sizes fit 2023 Aston Martin vehicles?
2023 Aston Martin vehicles use eight sizes across three model lines: 255/35R21, 255/40R20, 295/30R21, 295/35R20, 265/35R21, 305/30R21, 275/35R21, and 315/30R21. DB11 uses 255/35R21, 255/40R20, 295/30R21, and 295/35R20. DBS uses 265/35R21 and 305/30R21. Vantage uses 255/35R21, 255/40R20, 295/30R21, 295/35R20, 275/35R21, and 315/30R21. Rim diameters are either 20 or 21 inches, and the only confirmed rim-width range here is 8.5 to 10 inches for 255/40R20.
That means year and make alone are not enough for a correct match on a 2023 Aston Martin. You need the exact model first, then the actual wheel diameter, and then the specific front or rear size because these cars use staggered fitments. DB11 and Vantage share several combinations, but DBS stands apart with its own 21-inch pair. If you are replacing only one axle, verify the size directly on the tire already fitted to that wheel so you do not mix a 20-inch package with a 21-inch package.
What does 255/40R20 mean on a 2023 Aston Martin tire?
On a 2023 Aston Martin, 255/40R20 is a metric radial size. The 255 is the section width in millimeters, 40 is the aspect ratio, meaning the sidewall height is 40 percent of the section width, R indicates radial construction, and 20 is the wheel diameter in inches. This size appears on DB11 and Vantage applications. One currently represented example in this size carries a Y speed rating, which has a 186-mph ceiling, and a load rating of 1,819 pounds at 50 psi.
That decoding helps you distinguish wheel size from tire width and profile before comparing brands. A 255/40R20 cannot substitute for a 255/35R21 even though the section width looks similar, because the wheel diameter is different and the overall proportions change. On a 2023 Aston Martin, that matters because some cars in the range use 20-inch packages while others use 21-inch packages. Always match the exact size on the axle you are replacing, then confirm whether the tire's speed and load characteristics suit the way you use the car.
Do all 2023 Aston Martin models use the same tire size?
No, 2023 Aston Martin models do not use one common tire size across the range. DB11 and Vantage overlap in four sizes: 255/35R21, 255/40R20, 295/30R21, and 295/35R20. DBS uses a separate 21-inch staggered pair of 265/35R21 and 305/30R21. Vantage also has its own additional 21-inch combination of 275/35R21 and 315/30R21. All of these are radial sizes, but they are tied to specific models and wheel packages.
The practical effect is that identifying the car as simply a 2023 Aston Martin is only a starting point. Owners comparing DB11 and Vantage should still inspect the tire sidewalls or wheel package because those two models can be equipped with either 20-inch or 21-inch sizes. DBS owners should not assume interchange just because the car also runs 21-inch wheels. Front and rear fitments are staggered throughout the range, so replacing two rear tires with a size meant for the front axle will create a mismatch even if the wheel diameter sounds right.
Buying the Right Tire
What sidewall styles are available for 2023 Aston Martin tires?
The currently represented 2023 Aston Martin products use Blackwall sidewall styling. BFGoodrich offers the 255/40R20 as a Blackwall radial, and Nitto offers the 295/35R20 as a Blackwall radial. No whitewall, redline, or other heritage sidewall treatment appears in the current selection for these modern fitments. That matches the contemporary character of late-model Aston Martin applications, where understated performance styling is the norm.
For most 2023 Aston Martin owners, sidewall style will be a simpler decision than size or wheel diameter. The real priority is confirming the correct staggered fitment first, then choosing the tire that aligns with the car's intended use and appearance. Because the visible options here are all Blackwalls, the cosmetic choice is straightforward compared with vintage applications that might offer multiple period sidewall treatments. If appearance matters closely, compare the tire's shoulder shape and branding style as well as the sidewall color treatment.
What brands make tires for 2023 Aston Martin vehicles?
Two brands are currently represented for 2023 Aston Martin fitments here: BFGoodrich and Nitto. BFGoodrich appears in 255/40R20 with the g-Force Phenom T/A, and Nitto appears in 295/35R20 with the NT555 G2. Both are radial performance tires with Blackwall sidewalls. Other 2023 Aston Martin sizes in the range do not currently have a represented product to compare within this page's scope.
Brand matters most after the correct size has been nailed down, because Aston Martin fitments are highly specific by model and axle position. A buyer replacing 20-inch DB11 or Vantage tires can compare those represented BFGoodrich and Nitto options within their respective sizes, but that comparison does not automatically extend to the 21-inch fitments used elsewhere in the range. Start with the exact size on your car, then compare brand character, speed rating, and any available load information within that size rather than trying to choose a brand first.
What is the difference between BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 for the 2023 Aston Martin?
For a 2023 Aston Martin, the BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 are not direct alternatives in the same size. The BFGoodrich is represented in 255/40ZR20 with a Y speed rating, a 1,819-pound load rating at 50 psi, a Blackwall sidewall, a 20-inch rim diameter, and an approved rim-width range of 8.5 to 10 inches. The Nitto NT555 G2 is represented in 295/35ZR20XL 105W with a Blackwall sidewall and a 20-inch rim diameter. Their widths, profiles, and speed ratings differ, and they belong to different positions in a staggered setup.
That means the choice between them is usually determined by your car's required size rather than by preference alone. A DB11 or Vantage owner running a 20-inch package may encounter both tires in the broader fitment set, but one serves the narrower 255 section width while the other serves the wider 295 section width. Compare them only after identifying the exact axle and wheel they are meant for. Mixing them up would not be a brand decision; it would be a fitment error.
Fitting & Setup
What rim width do 2023 Aston Martin tires require?
Confirmed rim-width guidance for 2023 Aston Martin fitments appears for 255/40R20, which suits wheels from 8.5 to 10 inches wide. Confirmed rim diameters are 20 inches for 255/40R20 and 295/35R20, and 21 inches for 255/35R21, 295/30R21, 265/35R21, 305/30R21, 275/35R21, and 315/30R21. A tire's section width and profile need to match the wheel correctly, so rim diameter alone is not enough to confirm suitability.
For owners of a 2023 Aston Martin, the safest approach is to read the wheel and tire currently on the car before replacing anything. That is especially important on staggered applications, where front and rear wheels often differ in width even when they share the same diameter. If you are changing wheel packages or replacing a wheel as well as a tire, confirm the wheel's actual width against the tire manufacturer's approved range for that exact size. Do not assume one 20-inch or 21-inch Aston Martin wheel is interchangeable with every tire in that diameter.
Do 2023 Aston Martin tires require inner tubes?
The represented 2023 Aston Martin fitments are modern radial performance tires, and no tube-type marking appears on the available examples. The 255/40ZR20 BFGoodrich and 295/35ZR20XL 105W Nitto are both presented as contemporary radial tires without tube-type notation. That is consistent with modern low-profile performance applications using tubeless wheel-and-tire assemblies. The other sizes in the 2023 Aston Martin range do not currently have a represented product here to compare in the same way.
In practice, most owners of a 2023 Aston Martin will be working with tubeless assemblies, but the right check is always the tire sidewall and the wheel itself. If a wheel has been changed from original specification, confirm that the wheel is designed for tubeless use and that the valve stem condition is good before mounting new tires. On a late-model car like this, an air-retention problem is more likely to involve a wheel, bead seat, or valve issue than a need for an inner tube.
Maintenance, Storage & Longevity
How should I store a 2023 Aston Martin when the tires are fitted?
A 2023 Aston Martin should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Modern radial tires resist flat-spotting better than older bias-ply designs, but they still age from heat, UV exposure, and long static periods. If the car is parked for extended stretches, move it occasionally or use properly placed stands if that fits your storage routine and vehicle-support plan.
Good storage habits help preserve both the tire casing and the way the car feels when it returns to the road. A modern Aston Martin can hide tire aging until speed rises or the road gets demanding, so visible condition and age matter just as much as tread depth. Keep the storage floor dry, avoid petroleum contamination, and check pressure before and after long idle periods. If the car is stored with one side facing a window or door, rotate its position periodically to reduce uneven light and heat exposure.
How long do tires on a 2023 Aston Martin typically last?
Tires on a 2023 Aston Martin should be judged more by age, condition, and storage history than by mileage alone, especially on a collector-oriented or low-use performance car. A sound rule is to begin close inspection in the five- to seven-year range and to treat the ten-year point as a serious replacement threshold even if tread remains. The DOT date code on the sidewall gives the tire's week and year of manufacture, which is essential for age tracking.
That timeline matters because high-performance tires can look acceptable long after their rubber chemistry has begun to harden. A 2023 Aston Martin that sees occasional spirited use may still have low mileage when its tires have already aged out of their best service life. If the steering response feels harsher, wet grip seems reduced, or sidewall cracking begins to appear, age may be the issue rather than wear. Keep a written record of installation dates so age decisions do not depend on memory alone.
How often should tires on a 2023 Aston Martin be inspected?
Tires on a 2023 Aston Martin should be inspected before every drive and again before any longer trip or high-speed run. Look for sidewall cracking, cuts, punctures, bulges, uneven shoulder wear, and any loss of pressure. On staggered performance fitments, also check that the front and rear sizes match the car's intended setup and that no previous service has introduced a mismatch between axle positions.
Frequent inspection is especially valuable on a car that may sit for stretches and then be driven hard. Catching a slow air loss, impact bruise, or alignment-related wear pattern early can prevent damage to expensive wheels and preserve the handling balance Aston Martin engineered into the chassis. Make pressure checks part of the inspection rather than relying on appearance, since low-profile tires can be visually misleading. If one tire repeatedly loses air, investigate the tire, wheel, and valve stem together rather than topping it off and moving on.
Safety & Road Use
Are 2023 Aston Martin tires safe for highway driving?
2023 Aston Martin tires in these fitments are modern radials intended for contemporary road use, and the represented products carry substantial speed capability. The BFGoodrich 255/40ZR20 uses a Y speed rating with a 186-mph ceiling, while the Nitto 295/35ZR20XL 105W uses a W speed rating with a 168-mph ceiling. Those ratings are well beyond normal U.S. highway speeds. For real-world driving, tire condition, inflation, alignment, and the car's overall mechanical health matter more than the raw rating alone.
Highway safety still depends on using the exact size required by the car and axle, because a staggered Aston Martin setup is designed around specific front-to-rear dimensions. A tire with the wrong width, aspect ratio, or wheel diameter can upset handling even if it is a premium high-speed radial. Before any sustained highway trip, verify pressures cold, inspect for impact damage, and make sure the tires are not aging out. On a powerful GT or sports car, the tire has to work with the chassis, not just fit the wheel.
What inflation pressure should I use for 2023 Aston Martin tires?
Inflation pressure on a 2023 Aston Martin should follow the vehicle manufacturer's specification for the exact model, wheel package, and axle position. One represented 255/40ZR20 tire carries a maximum load of 1,819 pounds at 50 psi, but that figure is the tire's rated limit rather than a blanket service recommendation for every Aston Martin application. Pressure should never be transferred from one size to another just because the tires belong to the same year and make.
Use the factory placard or owner's literature as your starting point, then confirm you are looking at the right numbers for the exact front and rear combination on your car. That matters because DB11, DBS, and Vantage do not all share the same sizes, and staggered layouts often use different front and rear pressures. Check pressures cold, not after driving, and recheck them seasonally as ambient temperatures change. If your car has been fitted with a different wheel package, verify the intended pressure guidance before assuming the original placard still applies unchanged.
What should I check before taking a 2023 Aston Martin on a longer drive?
Before a longer drive in a 2023 Aston Martin, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and correct cold inflation. Confirm that the front and rear sizes match the car's intended staggered arrangement, and inspect valve stems and wheel condition at the same time. The spare, sealant kit, or roadside-support equipment should also be checked so you know what backup you actually have if something happens away from home.
A tire check should be part of a broader pre-drive inspection on any high-performance grand tourer or sports car. Brakes, fluids, battery condition, and suspension behavior all matter, but tires are the one contact point every mile depends on. If the car has been sitting, take a short local drive first to feel for vibration, pull, or pressure loss before committing to distance. Any fresh shimmy, steering change, or warning light deserves attention before the trip rather than after the first high-speed stretch.
