2019 Aston Martin sits at the modern grand touring end of the marque’s history, pairing British luxury and hand-built character with serious contemporary performance. In that model year, Aston Martin’s range stretched from the DB11 and Vantage to the more powerful DBS and the four-door Rapide, and tire sizing followed those distinct roles rather than one universal fitment. Across four models, six radial sizes appear, with the DB11 and Vantage sharing one 20-inch front-and-rear pairing while the DBS and Rapide each use their own 21-inch combinations. Before choosing a tire for 2019 Aston Martin, confirm your exact model first, then verify whether you need the 20-inch or 21-inch fitment package.
Which Tire Size Is Right for Your 2019 Aston Martin
Six tire sizes are used across 2019 Aston Martin vehicles, and they vary by model rather than being shared across the full range. The real decision starts with confirming the correct model and rim diameter first, since DB11 and Vantage use 20-inch fitments while DBS and Rapide use different 21-inch front-and-rear combinations. Understanding that distinction before choosing a product saves time and helps match the right tire to the right car.
Year(s): 2019|Fit(s): DB11, Vantage|Construction: Radial|Rim: 20 in
255/40R20 is a radial metric size with a 255-millimeter section width, a 40-series aspect ratio, and a 20-inch rim diameter. This size is specific to the DB11 and Vantage, and it is available from BFGoodrich in a Blackwall sidewall with a Y speed rating to 186 mph. Buyers usually choose this size when keeping the correct front fitment for those two models and wanting a modern high-performance radial.
Year(s): 2019|Fit(s): DB11, Vantage|Construction: Radial|Rim: 20 in
295/35R20 is a radial metric size with a 295-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. This size is specific to the DB11 and Vantage, and it is available from Nitto in a Blackwall sidewall with a W speed rating to 168 mph. Buyers usually choose this size when keeping the correct rear fitment for those two models and matching the wider rear tire these cars were designed around.
265/35R21 is a radial metric size with a 265-millimeter section width, a 35-series aspect ratio, and a 21-inch rim diameter. This size is specific to the DBS rather than universal across 2019 Aston Martin models. Choose it only if you are fitting the front position on a 2019 Aston Martin DBS and have confirmed the car uses the 21-inch DBS package.
305/30R21 is a radial metric size with a 305-millimeter section width, a 30-series aspect ratio, and a 21-inch rim diameter. This size is specific to the DBS and serves as the wider rear companion to its 21-inch front fitment. Choose it only if you are fitting the rear position on a 2019 Aston Martin DBS and want the proper size family for that model.
245/35R21 is a radial metric size with a 245-millimeter section width, a 35-series aspect ratio, and a 21-inch rim diameter. This size is specific to the Rapide rather than shared across the rest of the 2019 Aston Martin range. Choose it only if you are fitting the front position on a 2019 Aston Martin Rapide and have confirmed the car uses the 21-inch Rapide fitment.
295/30R21 is a radial metric size with a 295-millimeter section width, a 30-series aspect ratio, and a 21-inch rim diameter. This size is specific to the Rapide and pairs with its 21-inch front tire rather than fitting every 2019 Aston Martin model. Choose it only if you are fitting the rear position on a 2019 Aston Martin Rapide and want the correct rear size for that four-door grand tourer.
Four 2019 Aston Martin models are covered here: DB11, DBS, Rapide, and Vantage. Tire size varies by model, so year and make alone are not enough to choose the correct fitment; you need to identify the exact model and confirm whether it uses the 20-inch or 21-inch package. Select your model below to narrow the fitment history and see the tire options that apply to it.
2019 Aston Martin DB11
The DB11 is Aston Martin’s modern grand tourer, balancing long-distance comfort with the marque’s familiar front-engine performance character. Its tire package mounts on 20-inch wheels, with a staggered front-and-rear setup shared with the 2019 Vantage rather than the larger 21-inch fitments used on DBS and Rapide.
The DBS sits at the sharper, more powerful end of Aston Martin’s grand touring lineup, carrying a more aggressive stance and its own distinct tire package. Its tires mount on 21-inch wheels, with model-specific front and rear sizes that do not interchange with the DB11, Vantage, or Rapide combinations.
The Rapide brings Aston Martin styling and grand touring character into a four-door format, aimed at buyers who want performance with added passenger space. Its fitment uses 21-inch wheels and a staggered radial setup unique to the Rapide within the 2019 Aston Martin range.
The Vantage is Aston Martin’s more compact sports car, with a more focused personality than the larger DB11 while still carrying the brand’s luxury-performance identity. Its tires mount on 20-inch wheels, using the same staggered size pairing as the DB11 rather than the 21-inch setups found on DBS and Rapide.
Two products are available across two tire sizes for 2019 Aston Martin vehicles. The 255/40R20 front size uses a BFGoodrich radial Blackwall, while the 295/35R20 rear size uses a Nitto radial Blackwall; confirm your exact model and front-or-rear size before selecting.
These answers cover how 2019 Aston Martin tire sizes differ between DB11, DBS, Rapide, and Vantage, what the metric sizing codes mean, and what to verify about rim width, speed rating, and long-term care on a modern exotic used for collector or weekend driving.
Size Basics & Fitment
What tire sizes fit 2019 Aston Martin vehicles?
2019 Aston Martin vehicles use six sizes across four models. DB11 and Vantage use 255/40R20 front and 295/35R20 rear, both on 20-inch wheels. DBS uses 265/35R21 front and 305/30R21 rear, while Rapide uses 245/35R21 front and 295/30R21 rear, all on 21-inch wheels. Rim width guidance is available for 255/40R20 at 8.5 to 10 inches.
That means there is no single 2019 Aston Martin tire size that fits the whole model range. The first step is identifying the exact model, then confirming whether you are replacing the front or rear tire on a staggered setup. If you are working with DB11 or Vantage, you can narrow the search to the shared 20-inch package; if you have a DBS or Rapide, the 21-inch sizes are model-specific and should be matched carefully.
What does 255/40R20 mean on a 2019 Aston Martin tire?
On a 2019 Aston Martin, 255/40R20 means the tire is 255 millimeters wide, has a 40-series aspect ratio, and fits a 20-inch wheel. The R identifies it as a radial construction. This size is used on the front of the DB11 and Vantage, and one available version carries a Y speed rating, which is rated to 186 mph.
That code matters because each part affects fitment, not just overall size. A 255/40R20 belongs in the 20-inch front position for the models that use it, and it should also be checked against the wheel width; the available BFGoodrich version fits rims from 8.5 to 10 inches wide. Matching the full size code is more important than matching width alone when replacing a tire on a modern Aston Martin.
Do all 2019 Aston Martin models use the same tire size?
No, 2019 Aston Martin models do not all use the same tire size. DB11 and Vantage share a 20-inch staggered package with 255/40R20 front and 295/35R20 rear. DBS uses its own 21-inch pair, 265/35R21 and 305/30R21, while Rapide uses a different 21-inch pair, 245/35R21 and 295/30R21.
That split is important because year and make alone can point you in the wrong direction. Even within the same brand and model year, Aston Martin tuned these cars for different roles, so the correct tire depends on the exact car and axle position. Before replacing anything, confirm the model badge, check whether the car is front or rear staggered as expected, and verify the size molded into the existing tire sidewall.
Buying the Right Tire
What sidewall styles are available for 2019 Aston Martin tires?
The available 2019 Aston Martin fitments shown here use Blackwall sidewalls in both 255/40R20 and 295/35R20. That appearance suits a modern performance GT or sports car far better than the whitewall and pie-crust styles associated with earlier collector eras. Since every available product here is a radial performance tire, the sidewall presentation stays contemporary and understated.
For a 2019 Aston Martin, sidewall style is mostly an appearance and authenticity question rather than an old-versus-new construction debate. A clean Blackwall look is consistent with how late-model Aston Martins are typically equipped and judged visually. If appearance matters as much as fitment, compare the sidewall branding and profile details of the exact tire you are considering so the finished look matches the character of the car.
What brands make tires for 2019 Aston Martin vehicles?
Two brands cover the 2019 Aston Martin sizes with available products here. BFGoodrich offers the 255/40R20 front size used on DB11 and Vantage, while Nitto offers the 295/35R20 rear size used on those same models. Both are radial performance tires with Blackwall styling, but they apply to different positions in the staggered setup rather than serving as interchangeable alternatives.
That means brand choice may be tied to axle position as much as personal preference. On a staggered modern Aston Martin, the more important task is keeping the correct size on the correct wheel, then confirming the performance category and speed rating suit the car’s intended use. If you are replacing one tire in a pair, pay attention to how the new tire will match the remaining tire in construction, category, and overall appearance.
What is the difference between BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 for the 2019 Aston Martin?
BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 cover different 2019 Aston Martin sizes rather than the same fitment. The BFGoodrich version is a 255/40ZR20 with a 101Y service description, a 1,819-pound maximum load at 50 psi, and an approved rim width range of 8.5 to 10 inches. The Nitto version is a 295/35ZR20XL 105W, with a wider section size for the rear position and a different speed rating ceiling.
In practical terms, this is not a head-to-head choice between two interchangeable tires. The BFGoodrich fits the front 20-inch position used on DB11 and Vantage, while the Nitto fits the rear 20-inch position on those same cars. Compare them by intended position first, then by details such as speed rating and wheel-width compatibility, because the correct front-rear relationship matters more than selecting one brand name over another.
Fitting & Setup
What rim width do 2019 Aston Martin tires require?
Rim width guidance is available for the 2019 Aston Martin 255/40R20 size. That tire fits wheels from 8.5 to 10 inches wide and mounts on a 20-inch rim. The other sizes here are also tied to either 20-inch or 21-inch rim diameters by their size codes, but only the 255/40R20 fitment includes a published rim-width range in this group.
Wheel diameter must match the tire exactly, but width deserves the same attention before mounting. A tire can be the right diameter and still be a poor match if the wheel is too narrow or too wide for its approved range. When replacing tires on a 2019 Aston Martin, confirm the actual wheel dimensions on the car rather than assuming every factory-style wheel shares the same width across trims or axle positions.
Do 2019 Aston Martin tires require inner tubes?
The available 2019 Aston Martin tires here are modern radial performance sizes with no tube-type marking, and the 255/40ZR20 and 295/35ZR20 products follow tubeless passenger-car sizing conventions. Nothing in these fitments suggests an inner-tube application like you would expect on earlier tube-type collector tires. That aligns with the wheel and tire design normally used on late-model high-performance Aston Martins.
Even so, the right approach is to confirm the exact sidewall marking on the tire you choose and inspect the wheel condition at the same time. Air retention on a modern tubeless setup depends on clean bead seats, undamaged valve stems, and a wheel free from cracks or corrosion where the bead seals. If a car has aftermarket wheels, inspect them especially carefully before mounting a fresh set of tires.
Maintenance, Storage & Longevity
How should I store a 2019 Aston Martin when the tires are fitted?
A 2019 Aston Martin should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that can age rubber prematurely. Keep the tires properly inflated during storage and move the car periodically so the same contact patch is not carrying the load for months at a time. Modern radials resist flat-spotting better than vintage bias-ply tires, but long static storage still takes a toll.
Collector use often means long periods between drives, so storage habits have a direct effect on tire life. If the car will sit for an extended season, clean the tires, maintain pressure, and consider tire cradles or stands to reduce stress on the casing. When the car returns to service, inspect the sidewalls and tread before driving at speed, because appearance alone does not always reveal internal age-related hardening.
How long do tires on a 2019 Aston Martin typically last?
Tire life on a 2019 Aston Martin should be judged by age and condition as much as tread depth. A useful collector-car rule is to begin evaluating tires carefully around five to seven years of age and to treat roughly ten years as a point where replacement deserves serious consideration, even if the car has not covered many miles. The DOT date code on the sidewall tells you when the tire was built.
That matters because many Aston Martins are driven sparingly, and low mileage can make an older tire look healthier than it really is. Heat cycles, UV exposure, long storage, and inflation history all affect the structure of the tire over time. If the tires are several years old, a close inspection by a knowledgeable tire professional is worthwhile before any highway trip or spirited use.
How often should tires on a 2019 Aston Martin be inspected?
Tires on a 2019 Aston Martin should be inspected before every drive and again before any extended outing. Check inflation pressure, tread wear, visible cuts, bulges, punctures, and sidewall cracking, and look for signs that one axle is wearing differently from the other. On a staggered performance car, unequal wear can reveal alignment or suspension issues sooner than it would on a square setup.
A more thorough inspection every few months is a good habit for a car that alternates between storage and occasional use. Pay attention to valve stems, wheel lips, and any vibration that develops after the car has been sitting. Catching a problem early can prevent damage to the wheel and helps preserve the driving character these cars are known for when they return to the road.
Safety & Road Use
Are 2019 Aston Martin tires safe for highway driving?
2019 Aston Martin tires are designed as modern radial performance fitments, and the available examples here carry high-speed service ratings appropriate to the type of vehicle. The 255/40ZR20 BFGoodrich carries a Y rating, which is rated to 186 mph, while the 295/35ZR20XL Nitto carries a W rating, which is rated to 168 mph. Those limits exceed normal U.S. highway speeds by a wide margin when the tires are in sound condition and properly inflated.
Real-world safety depends on more than the speed symbol on the sidewall. Tire age, inflation pressure, alignment, suspension condition, and any prior impact damage matter just as much on a high-performance Aston Martin. Before sustained highway use, make sure all four tires are matched correctly to their positions and that the car has not been sitting long enough for age or storage issues to become the more important concern.
What inflation pressure should I use for 2019 Aston Martin tires?
Inflation pressure on a 2019 Aston Martin should follow the vehicle manufacturer’s recommendation first, since that accounts for the car’s weight distribution, intended axle loads, and handling balance. One available 255/40R20 tire carries a maximum load of 1,819 pounds at 50 psi, but that figure is the tire’s rated maximum, not a universal running pressure for every 2019 Aston Martin application. Pressure should never be copied from one size to another without confirmation.
The right process is to check the placard or owner’s manual for the front and rear pressures specified for your exact model, then compare that with the tire maker’s guidance for the replacement tire you are using. Modern Aston Martins often rely on very specific front-to-rear pressure balance, especially with staggered wheels. Set pressures cold, recheck them regularly, and revisit them whenever ambient temperatures change significantly.
What should I check before taking a 2019 Aston Martin on a longer drive?
Before a longer drive in a 2019 Aston Martin, inspect all four tires for cracking, cuts, punctures, bulges, abnormal wear, and correct cold inflation pressure. Confirm that the front and rear sizes are in the correct positions, since these cars use staggered setups, and inspect the spare or inflator kit if the car is equipped with one. A quick wheel check for damage or curb impact is equally worthwhile on low-profile tires.
Tires are only one part of the broader pre-drive routine on a modern exotic, but they are the part in direct contact with the road. After storage, pay extra attention to vibration, pressure loss, or any pull that suggests alignment or tire damage. If anything feels different in the first few miles, stop and inspect before continuing, rather than assuming the car simply needs to warm back up.
