The 2009 Aston Martin DB9 sits in the modern grand touring tradition, pairing hand-built British luxury with the long-hood, V12-powered character that made the model a centerpiece of Aston Martin’s early 21st-century lineup. Tire fitment on this car follows a staggered 19-inch radial setup, with 235/40R19 in front and 275/35R19 in the rear. That means the decision is less about finding one universal size and more about matching the front and rear positions correctly while comparing the available radial choices in each size. For owners focused on road manners, appearance, and proper fitment, wheel details and axle location both matter before making a selection.
Which Tire Size Is Right for The 2009 Aston Martin DB9
The 2009 Aston Martin DB9 uses two primary tire sizes, and they serve different positions on the car rather than different trim levels. Both are radial tires mounted on 19-inch wheels, so the first step is confirming whether you are replacing a front or rear tire, then checking that the wheel and overall setup still match the original staggered arrangement.
In 235/40R19, the 235 identifies the tire's nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2009 Aston Martin DB9, this size is used at the front and works as part of the car's staggered radial setup. Available choices in this size include a Blackwall BFGoodrich g-Force Phenom T/A, giving the buyer a modern performance-oriented option within the correct fitment range. Selecting this size means preserving the intended front tire position and confirming wheel width compatibility before installation.
In 275/35R19, the 275 denotes nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 19 designates the wheel diameter. On the 2009 Aston Martin DB9, this size is used at the rear, where it complements the narrower front tire in the factory-style staggered layout. Rear tire choices include Blackwall options from BFGoodrich and Nitto across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. This is the size to evaluate when replacing rear tires and maintaining the car's correct front-to-rear fitment balance.
Fitment across the covered 2009 Aston Martin DB9 and DB9 Volante configurations is consistent in size, with the same staggered front and rear tire arrangement used throughout. Checking the exact sub-model still matters so the correct axle position is matched and wheel hardware details are not overlooked during replacement.

2009 Aston Martin DB9 (21mm hex lug nut) Front
This front-position DB9 configuration uses the smaller of the two staggered radial sizes on a 19-inch wheel. Tire selection here should focus on maintaining the proper front axle fitment and confirming wheel width before comparing available product options.
This rear-position DB9 configuration uses the wider rear radial size that completes the staggered setup. Choosing the correct rear tire means matching the axle location properly and comparing the available Blackwall performance-oriented options in this size.
This front-position DB9 setup keeps the same front radial tire size as the other covered configurations. The key decision is selecting a tire that matches the front wheel specification and preserves the intended staggered relationship to the rear size.
This rear-position DB9 setup uses the same wider rear radial tire found across the covered model variations. Buyers should treat it as a rear-only fitment and verify wheel width and overall setup before choosing among the available series.
2009 Aston Martin DB9 Volante (21mm hex lug nut) Front
The DB9 Volante front configuration uses the same front radial tire size as the coupe-related listings in this coverage set. That keeps tire selection straightforward, with the main focus on front axle placement, wheel compatibility, and preserving the staggered arrangement.
2009 Aston Martin DB9 Volante (21mm hex lug nut) Rear
The DB9 Volante rear configuration uses the same rear radial size as the other covered versions of the 2009 DB9. Replacement choice should stay centered on rear-position fitment and on selecting among the available brands and tire series in that size.
2009 Aston Martin DB9 Volante (22mm hex lug nut) Front
This DB9 Volante front-position setup continues the same 19-inch front radial fitment used throughout the covered range. Tire selection is therefore less about model variation and more about getting the correct front size and wheel match.
2009 Aston Martin DB9 Volante (22mm hex lug nut) Rear
This DB9 Volante rear-position setup uses the wider rear tire that completes the staggered 19-inch package. Buyers should confirm they are replacing a rear tire specifically, then compare the available radial choices within the correct rear size.
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.

Tire Size & Fitment
What tire size fits a 2009 Aston Martin DB9?
The 2009 Aston Martin DB9 uses a staggered tire setup with 235/40R19 on the front and 275/35R19 on the rear. Both sizes are radial tires mounted on 19-inch wheels, so the car does not use the same tire size at all four corners.
That front-to-rear difference matters any time tires are replaced. A buyer should confirm axle position first, then make sure the car still has the expected wheel setup, especially if it has changed hands or has had aftermarket wheel work, suspension changes, or previous tire substitutions.
What size rim does a 2009 Aston Martin DB9 use?
The 2009 Aston Martin DB9 uses 19-inch rims with both of its primary tire sizes. The front 235/40R19 and rear 275/35R19 sizes both share the same rim diameter, even though the tire widths and aspect ratios differ between the two axle positions.
Sharing a 19-inch diameter does not make the front and rear tires interchangeable. Wheel width still needs to suit the tire being installed, and the correct tire must stay on its intended axle so the staggered fitment, handling balance, and physical clearance are preserved.
Why does the 2009 Aston Martin DB9 have more than one tire size?
The 2009 Aston Martin DB9 has more than one tire size because it uses a staggered arrangement: a narrower 235/40R19 in front and a wider 275/35R19 in the rear. This is a position-based fitment rather than a trim-level split, and it applies across the covered DB9 and DB9 Volante configurations.
For the owner, that means tire selection starts with identifying whether the replacement is for the front or rear axle. It is also worth checking that the car still carries the correct wheel widths and has not been converted to a nonstandard setup that changes how those tire sizes need to be evaluated.
Choosing the Right Tire
What should I consider when choosing a 235/40R19 and 275/35R19 tire set for a 2009 Aston Martin DB9?
Start with the correct staggered sizes: 235/40R19 for the front and 275/35R19 for the rear. From there, compare the available radial choices by axle position, wheel-width compatibility, tire series, brand, and any useful specification details such as weight or load figure where those details are offered.
A matching approach front to rear is important, but the front and rear do not have the same product selection. The car's current wheel setup, how it is driven, and whether the priority is straightforward replacement or a specific handling and appearance preference should guide the final comparison.
What sidewall styles are available for 2009 Aston Martin DB9 tires?
The available tires for the 2009 Aston Martin DB9 in these sizes use a Blackwall sidewall style. That applies to the front 235/40R19 option and to the rear 275/35R19 choices, so the visual presentation stays clean and contemporary rather than using whitewall or raised-letter treatments.
For most DB9 owners, that means sidewall appearance is not the main decision point on this page. Selection is more about choosing the correct front or rear size, then comparing the available brands and tire series while keeping the car's staggered fitment and wheel compatibility intact.
What brands offer tires for the 2009 Aston Martin DB9?
BFGoodrich and Nitto offer tires in the sizes used on the 2009 Aston Martin DB9. BFGoodrich appears in both the front and rear fitments, while Nitto is represented in the rear 275/35R19 size with the NT555 G2.
Brand choice should still come after confirming the tire's position on the car. A front replacement has a narrower field than a rear replacement, so the better comparison is not brand alone but brand plus tire series, wheel-width compatibility, and how closely the new tire matches the intended front or rear role.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Aston Martin DB9?
A period-style approach for a 2009 Aston Martin DB9 starts with keeping the original staggered format intact: 235/40R19 in front and 275/35R19 in the rear, both in radial construction on 19-inch wheels. That preserves the modern grand touring character the car was designed around rather than moving to an unrelated tire profile.
Appearance on this model is shaped more by proper proportion and stance than by vintage sidewall detailing. A buyer who wants the car to look right should focus on correct axle placement, matching wheel setup, and a tire series that complements the DB9's clean, contemporary design without forcing an off-era presentation.
Does correct tire fitment matter for a 2009 Aston Martin DB9 restoration?
Correct tire fitment matters on a 2009 Aston Martin DB9 restoration because the car uses a specific staggered setup rather than one all-around size. The 235/40R19 front and 275/35R19 rear pairing affects the car's stance, wheel fill, and overall visual balance as much as it affects basic fitment.
A restoration-minded owner should confirm the wheels remain the proper 19-inch pieces and have widths that suit the selected tires. Even on a newer collector car, altered wheels or past tire substitutions can change the finished look, so keeping the front and rear relationship correct is part of restoring the car's intended presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Aston Martin DB9?
Yes, modifications can affect tire fitment on a 2009 Aston Martin DB9 even when the nominal tire sizes stay the same. Aftermarket wheels, suspension changes, altered ride height, or previous changes in wheel width can all influence how a 235/40R19 front or 275/35R19 rear tire sits on the car.
That is why it helps to inspect the car before ordering replacements. Check wheel diameter and width, look for signs of rubbing at full steering lock or under suspension compression, and confirm that the current setup still supports the staggered front-and-rear arrangement the DB9 was designed to use.
What should I inspect before driving a 2009 Aston Martin DB9 on new tires?
Before driving a 2009 Aston Martin DB9 on new tires, inspect the wheel condition, verify that the front and rear sizes have been installed in the correct positions, and confirm proper inflation. It is also wise to look over the valve stems, check for bead seating issues, and make sure no fender or suspension contact appears.
A short, careful road test is the next practical step. Pay attention to vibration, pull, rubbing, or any unusual steering feel, then recheck tire pressure after the first drive. On a staggered car like the DB9, a simple front-versus-rear installation mistake can create problems even when both tires are 19-inch radials.
How often should tires on a 2009 Aston Martin DB9 be inspected?
Tires on a 2009 Aston Martin DB9 should be inspected regularly, not only by mileage but also by time and storage conditions. A low-use grand touring car can spend long periods parked, so tread depth alone is not enough; sidewall condition, air retention, and overall aging all deserve routine attention.
Monthly pressure checks are a sensible baseline, with closer inspection before longer drives or after the car has been stored. Watch for cracking, bulges, punctures, uneven wear, or signs that the front and rear tires are not wearing as expected, since those clues can point to alignment or setup issues.
