In 2009 Aston Martin balanced traditional grand touring character with modern performance across a compact but clearly separated lineup. The DB9 and V8 Vantage carried the marque’s core road-car identity, while the DBS pushed further into flagship territory with a more aggressive stance and larger wheel package. Across these three models, four radial tire sizes appear, with the DB9 and V8 Vantage sharing 19-inch fitments and the DBS using its own 20-inch sizes. For most buyers, the first step is confirming whether the car is a DB9, DBS, or V8 Vantage, because the model determines both the correct size set and the wheel diameter your tires must match.
Which Tire Size Is Right for Your 2009 Aston Martin
Four tire sizes are used across 2009 Aston Martin vehicles, and they vary by model rather than being shared across the full range. The real decision starts with confirming the model and wheel diameter first, since DB9 and V8 Vantage use 19-inch fitments while the DBS moves to 20-inch fitments. Understanding that split before choosing a product saves time and helps ensure the right match.
Year(s): 2009|Fit(s): DB9, V8 Vantage|Construction: Radial|Rim: 19 in
The 235/40R19 is a radial metric size with a 235-millimeter section width, 40-series aspect ratio, and 19-inch rim diameter, and it is specific to the front fitment used on the DB9 and V8 Vantage rather than the full 2009 Aston Martin range. It is available from BFGoodrich in Blackwall form, with a Y speed rating up to 186 mph and a published load figure of 1,565 pounds at 50 psi. This size suits owners keeping the original 19-inch front fitment on those two models and wanting a modern radial for road use.
Year(s): 2009|Fit(s): DB9, V8 Vantage|Construction: Radial|Rim: 19 in
The 275/35R19 is a radial metric size with a 275-millimeter section width, 35-series aspect ratio, and 19-inch rim diameter, and it is the matching 19-inch rear size for the DB9 and V8 Vantage rather than a universal Aston Martin fitment. BFGoodrich and Nitto both offer this size, all in Blackwall form, and speed ratings vary by product between W at 168 mph and Y at 186 mph. This is the right choice for owners preserving the staggered 19-inch setup those models were built around while selecting among different modern radial product lines.
Year(s): 2009|Fit(s): DBS|Construction: Radial|Rim: 20 in
The 245/35R20 is a radial metric size with a 245-millimeter section width, 35-series aspect ratio, and 20-inch rim diameter, and it is specific to the DBS front axle. BFGoodrich and Nitto offer it in Blackwall form, with W speed ratings up to 168 mph across the available products and a published load figure of 1,521 pounds at 50 psi on one BFGoodrich option. This size is the correct starting point for a DBS owner retaining the model’s 20-inch front wheel fitment and looking for a contemporary radial tire.
Year(s): 2009|Fit(s): DBS|Construction: Radial|Rim: 20-in rim
The 295/30R20 is a radial metric size with a 295-millimeter section width, 30-series aspect ratio, and 20-inch rim diameter, and it serves as the DBS rear fitment rather than a shared size across all 2009 Aston Martin models. This size does not have a product offering here, so the key point is its role as the matching rear size for the DBS 20-inch staggered setup. DBS owners should treat it as a model-specific rear size and confirm the exact wheel and application before moving forward.
Three 2009 Aston Martin models are covered here. Tire size varies by model, with the DB9 and V8 Vantage sharing one 19-inch staggered fitment and the DBS using a separate 20-inch staggered fitment, so year and make alone are not enough to choose correctly. Select your model below to narrow the fitment history and products to the car you actually own.
2009 Aston Martin DB9
The 2009 Aston Martin DB9 was the marque’s signature grand tourer, blending long-distance refinement with the proportion and presence buyers expect from a modern Aston. Its tires mount on 19-inch wheels, and the shared DB9/V8 Vantage sizing reflects a performance-oriented staggered setup rather than a one-size-fits-all arrangement across the brand.
The 2009 Aston Martin DBS sat at the sharper, more aggressive end of the range, with a more focused personality than the DB9 while still carrying true Aston Martin GT credentials. Its tire package moves to 20-inch wheels, making it distinct from the DB9 and V8 Vantage and reinforcing why the model name matters before choosing tires.
The 2009 Aston Martin V8 Vantage brought a smaller, more agile feel to the lineup, aimed at drivers who wanted Aston style with a sportier edge. Like the DB9, it uses 19-inch tires, but the car’s shorter-wheelbase sports-car character can make owners especially attentive to preserving the intended front-to-rear sizing balance.
Nine products are available across four tire sizes for 2009 Aston Martin vehicles. The 235/40R19 has one BFGoodrich radial in Blackwall, 275/35R19 has four BFGoodrich and Nitto radials in Blackwall, and 245/35R20 has four BFGoodrich and Nitto radials in Blackwall. Confirm your model and exact front or rear size before selecting.
These FAQs cover the model-specific 19-inch and 20-inch fitments used across 2009 Aston Martin vehicles, plus rim width, speed rating, storage, and longer-drive considerations for modern high-performance radials on collector-minded cars.
Size Basics & Fitment
What tire sizes fit 2009 Aston Martin vehicles?
2009 Aston Martin vehicles use four sizes split by model. The DB9 and V8 Vantage use 235/40R19 at the front and 275/35R19 at the rear, both on 19-inch rims. The DBS uses 245/35R20 at the front and 295/30R20 at the rear, both on 20-inch rims. Published rim width ranges appear for 235/40R19 at 8 to 9.5 inches, 275/35R19 at 9 to 11 inches, and 245/35R20 at 8 to 9.5 inches.
That means there is no single tire size that fits every 2009 Aston Martin model. The practical first step is identifying the exact model and whether you are replacing the front pair, the rear pair, or the full staggered set. On cars with factory-style staggered fitment, mixing the wrong front and rear dimensions can alter appearance and handling balance, so it is worth checking the sidewall on the tires already mounted and confirming the wheel diameter before ordering replacements.
What does 235/40R19 mean on a 2009 Aston Martin tire?
On a 2009 Aston Martin, 235/40R19 is a metric radial size. The 235 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. Within the 2009 Aston Martin range, that size belongs to the DB9 and V8 Vantage on 19-inch front wheels, not to the DBS.
The code matters because a modern Aston Martin front tire is more than just a diameter match. Width, profile, and construction all affect clearance and the relationship to the matching rear size. If your car is a DB9 or V8 Vantage and still uses its original wheel concept, 235/40R19 is the front-size starting point. It should still be verified against the actual wheel and existing tire before replacing only one axle.
Do all 2009 Aston Martin models use the same tire size?
No. The 2009 Aston Martin DB9 and 2009 Aston Martin V8 Vantage share the same 19-inch staggered sizes, while the 2009 Aston Martin DBS uses a different 20-inch staggered combination. That split is important because the shared year and make do not guarantee a shared wheel diameter or shared front and rear dimensions across the range.
For a buyer, the takeaway is simple: confirm the model before narrowing the tire choice. A DB9 owner and a V8 Vantage owner can often start from the same size pair, but a DBS owner needs to look at a different front and rear package entirely. If the car has changed hands or wears aftermarket wheels, the safest approach is to verify both the sidewall markings and the wheel diameter currently on the car before moving ahead.
Buying the Right Tire
What sidewall styles are available for 2009 Aston Martin tires?
The available 2009 Aston Martin fitments here use Blackwall sidewalls across the supported 19-inch and 20-inch sizes. That applies to the 235/40R19, 275/35R19, and 245/35R20 products. For a 2009 Aston Martin, that appearance aligns naturally with the car’s modern performance-era character, where low-profile radial tires and clean sidewalls suit the original visual intent better than vintage-style whitewall treatments.
Sidewall style may seem secondary, but it changes how authentic the car looks at a glance. On a neo-classic performance car such as a 2009 Aston Martin, Blackwall is generally the expected visual choice for owners preserving factory-era appearance. Once the correct size is settled, the next comparison is usually between tire series, speed rating, and wheel-width compatibility rather than decorative sidewall treatment.
What brands make tires for 2009 Aston Martin vehicles?
BFGoodrich and Nitto cover the supported 2009 Aston Martin sizes that have product offerings here. BFGoodrich appears in 235/40R19, 275/35R19, and 245/35R20, while Nitto appears in 275/35R19 and 245/35R20. All of those offerings are radial Blackwall tires aimed at modern high-performance road use rather than vintage-style reproduction fitments.
Brand choice matters most after the correct size has been pinned down for your model and axle position. A DB9 or V8 Vantage owner comparing 275/35R19 rear tires can cross-shop BFGoodrich and Nitto in the same size, while the 235/40R19 front fitment is narrower in available brand coverage. A DBS owner has multiple choices at 245/35R20 front, but should still keep the front and rear pairing appropriate to the car’s original staggered setup.
What is the difference between BFGoodrich and Nitto options for the 2009 Aston Martin 275/35R19?
In 275/35R19 for a 2009 Aston Martin DB9 or V8 Vantage, BFGoodrich offers multiple series and Nitto offers the NT555 G2. All are Blackwall radials, but speed ratings vary: BFGoodrich appears in both W-rated 168 mph and Y-rated 186 mph versions, while the Nitto example is W-rated at 168 mph. Published weights also differ slightly, with the BFGoodrich and Nitto choices sitting close to one another in the upper-20-pound to low-30-pound range.
That means the comparison is less about basic fit and more about the exact tire line you want on the rear axle. If speed rating, load detail, or wheel-width guidance matters to your application, compare the individual series rather than assuming every 275/35R19 behaves the same. Keeping both rear tires matched by brand and series is usually the cleanest approach on a staggered-performance Aston Martin.
Fitting & Setup
What rim width do 2009 Aston Martin tires require?
Rim width guidance for 2009 Aston Martin tires depends on the size. The 235/40R19 fits rims from 8 to 9.5 inches wide, the 275/35R19 fits rims from 9 to 11 inches wide, and the 245/35R20 fits rims from 8 to 9.5 inches wide. Those ranges support the DB9 and V8 Vantage 19-inch setup and the DBS 20-inch front fitment, while still leaving wheel-width confirmation as an important final step.
Rim width influences sidewall shape and how the tread sits on the road, so it is not something to guess at by eye. If your wheels are original, those ranges are a useful check against the factory-style package. If the car has aftermarket wheels, confirm the actual width before selecting a tire, especially on low-profile 35- and 40-series fitments where small width changes can affect appearance and clearance.
Do 2009 Aston Martin tires require inner tubes?
The supported 2009 Aston Martin tire offerings here are modern radial performance tires and do not carry tube-type markings. Their construction and sizing format fit the tubeless norm used on late-model high-performance road cars. That matches the design expectations of a 2009 Aston Martin far more closely than older collector applications where tube-type and tubeless choices can overlap.
Even so, tube questions are ultimately wheel questions as much as tire questions. If the car still has its original late-model wheels in sound condition, tubeless fitment is the normal expectation. If a wheel has been replaced, repaired, or modified, inspect the bead seats and valve stem condition carefully before mounting new tires so the finished setup seals and balances correctly.
Maintenance, Storage & Longevity
How should I store a 2009 Aston Martin when the tires are fitted?
A 2009 Aston Martin should be stored in a cool, dry, dark space away from direct sunlight, electric motors, furnaces, welders, and other ozone sources that can age rubber prematurely. Keep the tires properly inflated during storage and avoid letting the car sit for long periods on underinflated tires. Because these are low-profile radials, they generally recover from short-term parking better than older bias-ply designs, but long static periods still deserve attention.
If the car will sit for months, roll it periodically to change the contact patch or place it on stands in a way that follows safe storage practice for the suspension and chassis. Clean, dry surfaces are better than dirt or damp concrete, and tire dressings that leave oily residue are best avoided. A careful storage routine protects both the rubber and the refined ride quality owners expect from an Aston Martin.
How long do tires on a 2009 Aston Martin typically last?
On a 2009 Aston Martin, tire age usually matters more than tread depth alone. Collector and low-mileage cars often keep plenty of visible tread even as the rubber hardens with time, so a tire should be evaluated regularly once it reaches roughly five to seven years of age, with replacement commonly considered around the ten-year mark. The DOT date code on the sidewall is the starting point for that timeline.
That approach is especially important on a performance car with wide rear tires and low profiles, because aging rubber can change grip and ride quality before the tread looks worn out. If the car is driven infrequently, include calendar age in every maintenance review rather than relying on mileage. A younger tire in the correct size is usually a better long-term decision than an older one that only appears fresh.
How often should tires on a 2009 Aston Martin be inspected?
Tires on a 2009 Aston Martin should be inspected before every drive and again before any extended outing. Look for sidewall cracking, bulges, cuts, uneven wear, embedded debris, and pressure loss, and check that the valve stems remain in good condition. On a staggered-performance car, it is also wise to compare both tires on the same axle for matching size, similar wear, and consistent condition.
Frequent inspection matters because low-mileage collector use can hide age-related problems until the car is finally taken on a longer trip. A quick walkaround and pressure check take only a few minutes, but they can reveal issues early enough to avoid vibration, poor handling, or roadside trouble. Include the spare in the same routine if the car still carries one, since emergency tires age too.
Safety & Road Use
Are 2009 Aston Martin tires safe for highway driving?
Yes, the supported 2009 Aston Martin tires are modern radial performance tires intended for highway use, and their speed ratings are well beyond normal U.S. road speeds. The available sizes include W-rated products up to 168 mph and Y-rated products up to 186 mph, depending on the exact size and tire series. On a road car such as a 2009 Aston Martin, those ratings generally exceed the demands of ordinary interstate travel.
Highway safety still depends on more than the speed symbol on the sidewall. Tire age, inflation, alignment, suspension condition, and brake health matter just as much, especially on a powerful GT car that may spend long periods parked between drives. Choose the correct front and rear sizes for the model, keep the tires in matched pairs by axle, and inspect them carefully before any sustained higher-speed trip.
What inflation pressure should I use for 2009 Aston Martin tires?
Inflation pressure on a 2009 Aston Martin should follow the vehicle’s factory recommendation for the specific model and axle position first, because front and rear pressures on staggered high-performance cars are often not the same. Tire load figures here include examples such as 1,565 pounds at 50 psi for 235/40R19, 1,764 pounds at 50 psi for one 275/35R19, and 1,521 pounds at 50 psi for one 245/35R20, but those are maximum load-and-pressure ratings, not blanket running-pressure instructions.
The practical approach is to use the owner’s manual or door-jamb placard for the baseline and then confirm that the mounted tire is appropriate for that operating range. Do not transfer a pressure figure from a 19-inch DB9 or V8 Vantage fitment to a 20-inch DBS tire, and do not assume the front and rear settings should match. Pressure should always be checked cold for a meaningful reading.
What should I check before taking a 2009 Aston Martin on a longer drive?
Before taking a 2009 Aston Martin on a longer drive, inspect all four tires for cracking, cuts, punctures, bulges, and uneven wear, then verify cold pressures and confirm that the front and rear sizes match the intended staggered setup for the model. Look over the valve stems, check for vibration or pull during a short local test drive, and make sure any spare tire and inflation equipment are usable. Tire condition is only one part of the broader pre-drive review on a modern collector-performance car.
A longer trip is also the right time to think beyond the tread face. Check brake feel, fluid condition, battery health, and whether the car has been sitting long enough for flat spotting or pressure loss to develop. If anything feels unsettled in the first few miles, stop and inspect rather than assuming it will clear up on its own. A careful pre-drive routine preserves both safety and enjoyment.
