2010 Aston Martin Tire Fitment Guide

2010 Aston Martin vehicles use eight sizes across five models. DB9 and V8 Vantage use 235/40R19 front and 275/35R19 rear. DBS uses 245/35R20 front and 295/30R20 rear. Rapide uses 245/40R20 front and 295/35R20 rear. V12 Vantage uses 255/35R19 front and 295/30R19 rear. The 19-inch applications and 20-inch applications do not interchange simply because they share the Aston Martin name, and several of these sizes also have their own rim-width ranges where that information is available.

The practical takeaway is that 2010 Aston Martin fitment starts with the exact model, then the axle position. Many owners know they have a DB9 or Vantage but do not immediately realize the car uses a staggered arrangement, meaning the front and rear tires are different sizes by design. If your car has replacement wheels, verify the actual wheel diameter and width before selecting a tire, especially on the 19-inch front fitments where recommended rim-width ranges differ by size.

On a 2010 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. For this model year, that size is used on the front of the DB9 and V8 Vantage, both of which share the same 19-inch front fitment.

That code matters because it tells you far more than just overall size. It confirms the tire belongs on a 19-inch wheel and preserves the low-profile proportions engineered into those cars. For the 235/40R19 products available here, recommended rim width falls in the 8- to 9.5-inch range, so owners with aftermarket wheels should compare that tire-to-wheel relationship before moving ahead.

No, 2010 Aston Martin models do not all use the same tire size. DB9 and V8 Vantage share one staggered 19-inch combination, but DBS, Rapide, and V12 Vantage each use their own front-and-rear pairings. Even where two cars share the same wheel diameter, the actual section width and aspect ratio can differ substantially, especially between the GT-oriented and more performance-focused models.

That means year and make are only the beginning of the search. Choosing by Aston Martin badge alone can easily put a 20-inch DBS or Rapide owner into the wrong front or rear size, or put a V12 Vantage owner into the DB9 and V8 Vantage pairing. If you are comparing cars in the same garage or replacing one axle at a time, confirm both the model and axle position before you narrow the tire options.

Most 2010 Aston Martin tire sizes here are available in Blackwall form, which suits the restrained, modern appearance expected on a Gaydon-era Aston Martin. The one exception in this group is 245/40R20, the Rapide front size, which is also available with an RWL sidewall. That gives Rapide owners a broader visual choice than the rest of the range, where Blackwall remains the standard look.

For most owners, Blackwall will be the more era-appropriate appearance on a 2010 Aston Martin, especially on DB9, DBS, V8 Vantage, and V12 Vantage. An RWL sidewall changes the visual character in a noticeable way and leans more custom than factory-like on a modern Aston. If the car is being kept close to original presentation, sidewall appearance matters almost as much as the actual size and should be chosen with the car's intended look in mind.

BFGoodrich, Nitto, and Pro-Trac cover the 2010 Aston Martin sizes here, though not every brand appears in every fitment. BFGoodrich covers 235/40R19, 275/35R19, 245/35R20, 245/40R20, and 255/35R19. Nitto covers 275/35R19, 245/35R20, 245/40R20, and 295/35R20. Pro-Trac appears in 245/40R20, which is the Rapide front size.

Brand choice becomes more limited as the fitment becomes more specialized. A shared size such as 275/35R19 gives DB9 and V8 Vantage owners more room to compare series and speed ratings, while niche rear sizes have fewer choices. Start by identifying the exact size your car needs on each axle, then compare the available brands within that size rather than assuming the same brand or series will cover the whole car.

On sizes where both appear, the BFGoodrich g-Force Comp-2 A/S and g-Force Phenom T/A differ in speed rating and, in some cases, published load information and weight. In 275/35R19, the Comp-2 A/S carries a 96W rating while the Phenom T/A carries a 100Y rating and a max load of 1,764 pounds at 50 psi. In 245/40R20, the Comp-2 A/S is 99W XL while the Phenom T/A is 99Y with a max load of 1,709 pounds at 50 psi.

That comparison matters most when you want to stay close to a specific performance envelope or need a published load-and-pressure figure to compare against your use. A W rating carries a 168 mph ceiling, while a Y rating carries a 186-plus mph ceiling. The right choice is not about one being universally better; it is about selecting the size-specific product whose rating, load information, and overall character align with your car's intended use.

Several 2010 Aston Martin sizes here include recommended rim-width ranges. 235/40R19 fits 8 to 9.5 inches. 275/35R19 fits 9.0 to 11.0 inches. 245/35R20 fits 8.0 to 9.5 inches. 245/40R20 fits 8.0 to 9.5 inches. 255/35R19 fits 8.5 to 10.0 inches. Rear 295-series applications in this group do not carry a rim-width range in the available specifications shown here.

Wheel width matters because the same nominal tire size can behave differently when mounted at the narrow or wide end of its approved range. On a 2010 Aston Martin with aftermarket wheels, verify both diameter and actual wheel width before choosing a tire. That is especially important if you are replacing only one axle, because the front sizes and rear sizes often differ not just in section width, but also in what wheel width they are designed to support.

A 2010 Aston Martin's original wheels are intended to be used with the car's paired front and rear tire sizes, not interchangeably across axles. DB9 and V8 Vantage use 19-inch front and rear wheels with different tire sizes, DBS and Rapide use 20-inch front and rear wheels with different tire sizes, and V12 Vantage uses a unique 19-inch front and rear pairing. Matching rim diameter is only the first step in confirming compatibility.

Even when both ends of the car use the same diameter, the wheel widths are typically different because the fitment is staggered. That means a front tire should not be chosen on the assumption that it can be mounted on the rear wheel, or vice versa, without checking the wheel width against the tire's approved range. If your Aston still has its factory wheels, keep the original front and rear positions in mind as you evaluate replacement tires.

A 2010 Aston Martin should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, battery tenders, furnaces, and other ozone-producing sources. Modern high-performance radials tolerate storage better than older bias-ply designs, but low-profile tires on heavy, powerful GT cars can still develop temporary flat spotting if the car sits in one position for long periods. Clean floors, moderate temperatures, and stable inflation pressure all help preserve the tire casing.

If the car is stored for weeks or months at a time, move it periodically or use stands in a way that supports the vehicle safely and appropriately. Avoid parking long-term on damp concrete, gravel, or surfaces contaminated with petroleum products. Before returning the car to regular use, check pressure, inspect the sidewalls for weathering or impact damage, and make sure each tire rolls smoothly after the first few miles.

On a 2010 Aston Martin, tire age is usually a more important replacement factor than mileage. Collector and specialty-use cars often accumulate miles slowly, so a tire can still look serviceable in tread depth while aging out in the casing and sidewall. A sensible rule is to begin evaluating tires closely around five to seven years of age and to treat ten years as a serious replacement threshold, regardless of how much tread remains.

The best way to judge age is by the DOT date code on the sidewall, then by condition and use history. Heat cycles, storage conditions, and long periods of inactivity all affect service life, especially on a high-performance car with low-profile tires. If your Aston Martin still wears older tires that have spent years parked more than driven, replacement on age alone can be the smarter move even if the tread appears hardly used.

Tires on a 2010 Aston Martin should be inspected before every drive, and again more carefully before any longer trip or sustained high-speed use. Check for cracking, cuts, bulges, punctures, uneven wear, and pressure loss, especially on the inside shoulders where low-profile performance tires can hide wear from a quick glance. Because these cars use staggered fitments, compare each tire against its correct axle position rather than assuming all four should look the same.

A deeper inspection every few months is worthwhile even if the car is driven sparingly. Look at tread depth across the full width, confirm valve stem condition, and pay attention to any vibration or tramlining that has changed over time. Regular inspection is especially important on a modern exotic that may spend long stretches parked, since age, storage, and old impact damage often reveal themselves before mileage-related wear does.

A 2010 Aston Martin DB9 was originally designed around modern radial performance tires in a staggered 19-inch arrangement, using 235/40R19 at the front and 275/35R19 at the rear. By 2010, radial construction was standard for high-performance luxury GT cars, so the key originality points are the correct size, the proper front-and-rear pairing, and a sidewall look that suits the car's contemporary factory presentation. Specific original-supplier branding can vary by market and production timing.

For an owner focused on authenticity, the safest approach is to preserve the original size layout first and then choose a sidewall style that matches the car's intended presentation. Blackwall is the natural visual fit for a DB9 of this era. If the car is being prepared for marque judging or a highly exact restoration, verify market-specific details through Aston Martin club resources or model specialists before treating any one brand as universal across all 2010 DB9s.

Correct tire fitment does matter when showing a 2010 Aston Martin, even though the car is a modern classic rather than an early collector car. Judges and knowledgeable enthusiasts will notice whether the car carries the right front and rear sizes, whether the wheel diameter suits the model, and whether the sidewall appearance matches the car's original character. A 20-inch Rapide or DBS fitment on a 19-inch Vantage-family car would stand out immediately as incorrect.

Authenticity on a 2010 Aston Martin is usually less about period-style pie crusts or wide whitewalls and more about preserving the car's factory stance, proportions, and modern performance aesthetic. Blackwall sidewalls generally align best with that expectation. If your goal is concours-level accuracy, size and axle placement should be treated as non-negotiable, while brand preference can be refined with help from marque clubs and event-specific judging standards.

Where both appear in the same 2010 Aston Martin size, BFGoodrich g-Force Sport Comp-2 and Nitto NT555 G2 are close modern radial performance choices, but they differ in published weight and, in some fitments, in how much specification detail accompanies them. In 275/35R19, the BFGoodrich weighs 30 pounds while the Nitto weighs 29.54 pounds, and both carry a W speed rating. In 245/35R20, the BFGoodrich weighs 28 pounds and the Nitto 28.21 pounds, again with W ratings.

That makes the comparison less about a dramatic spec gap and more about choosing the product character and brand preference you want within the correct size. When two tires share the same speed ceiling and closely similar physical specs, details such as sidewall branding, tread family, and how they complement the car's intended use become the deciding factors. Owners replacing one axle pair often compare those nuances after first locking in the exact size their Aston requires.

Yes, the 2010 Aston Martin sizes covered here are modern radial performance tires suitable for highway use when they are the correct size, in sound condition, and properly inflated. Speed ratings in this group run from W to Y depending on size and product. W carries a 168 mph ceiling, while Y carries a 186-plus mph ceiling. Those ratings are well beyond normal U.S. highway speeds, and on a modern Aston Martin the condition of the tire usually matters more than the raw letter on the sidewall during ordinary road use.

The bigger safety issue is using the right size on the right axle and making sure the tire is fresh enough to trust. A high-performance grand tourer or sports car can place heavy demands on its tires during braking, cornering, and sustained heat cycling, even at legal road speeds. Before longer highway driving, check age, pressure, wear pattern, and any signs of impact damage, especially if the car has spent much of its life parked.

Inflation pressure on a 2010 Aston Martin should follow the vehicle's factory guidance first, with the tire maker's maximum-rated pressure treated as a product limit rather than a blanket running recommendation. Some tires here also publish load-at-pressure figures: 235/40R19 supports 1,565 pounds at 50 psi, 275/35R19 up to 1,764 pounds at 50 psi in one application, 245/35R20 up to 1,521 pounds at 50 psi, 245/40R20 up to 1,709 pounds at 50 psi, and some 255/35R19 products reach 1,565 or 2,041 pounds at 50 psi depending on the tire.

Those figures should not be transferred from one size to another or treated as the pressure you should automatically run on the car. Aston Martin's own pressure recommendations account for weight distribution, suspension tuning, and the front-rear stagger built into each model. Start with the door-jamb or owner's-manual specification for your exact model, then adjust only within responsible limits if your tire manufacturer and your use case support it.

Before taking a 2010 Aston Martin on a longer drive, inspect all four tires for cuts, cracking, bulges, exposed cords, punctures, and irregular wear. Confirm cold pressures, verify that the front and rear sizes are mounted in the correct positions, and check that the spare or inflation solution is usable if your car carries one. On low-profile radials, also look closely at the inner and outer rim areas for evidence of curb strikes or pothole damage that may not be obvious from a distance.

Tires are only one part of a longer-trip check on a modern exotic, but they are the part that meets the road. A tire with plenty of tread can still be a weak link if it is old, heat-cycled, or damaged from storage and impact. Once the tires pass inspection, it is wise to include brakes, fluid levels, battery condition, and suspension feel in the rest of the pre-drive routine so the car is prepared as a complete system.
