By 2004, Aston Martin balanced old-world grand touring character with sharper modern performance, offering the DB7 and the flagship Vanquish as distinctly different expressions of the marque. Both carried the long-hood, hand-finished appeal buyers expect from Gaydon-era Aston Martin, but their tire requirements were not interchangeable. Across 2004 Aston Martin models, six radial sizes appear, with the DB7 using four sizes split between 18- and 19-inch fitments and the Vanquish using its own 19-inch front-and-rear pairing. The first step is to confirm whether you have a DB7 or a Vanquish, then verify whether your car is on its 18- or 19-inch wheel setup before choosing a tire.
Which Tire Size Is Right for Your 2004 Aston Martin
Six tire sizes are used across 2004 Aston Martin models, and they vary by model rather than being shared across the full range. Every size here is a radial, so the key decision is identifying the correct model and wheel diameter first, especially since the DB7 spans both 18- and 19-inch fitments while the Vanquish uses its own 19-inch staggered setup. Understanding that distinction before choosing a product saves time and helps match the tire to the car correctly.
Year(s): 2004|Fit(s): DB7|Construction: Radial|Rim: 19 in
245/35R19 is a metric radial size with a 245-millimeter section width, a 35-series aspect ratio, and fitment for a 19-inch wheel. This size is available from BFGoodrich and Nitto in blackwall form, and the products shown here carry W speed ratings to 168 mph. On 2004 Aston Martin fitment, this size is specific to the DB7 rather than universal across the year and make. It suits an owner keeping a DB7 on its 19-inch wheel package and looking for a modern radial tire in the correct size.
Year(s): 2004|Fit(s): DB7|Construction: Radial|Rim: 18 in
245/40R18 is a metric radial size with a 245-millimeter section width, a 40-series aspect ratio, and fitment for an 18-inch wheel. It is available in blackwall form from M&H Racemaster, BFGoodrich, and Nitto, and speed ratings vary by product, including W at 168 mph and Y at 186 mph or higher. This size is specific to the DB7 and belongs to the 18-inch setup rather than every 2004 Aston Martin model. It is the right path for a DB7 owner who has confirmed 18-inch wheels and wants to stay with the factory-type diameter class for that package.
265/30R19 is a metric radial size with a 265-millimeter section width, a 30-series aspect ratio, and fitment for a 19-inch wheel. Blackwall radial choices define this size category for the 2004 Aston Martin DB7. This size is specific to the DB7 and pairs with the car's 19-inch staggered fitment rather than the broader Aston Martin range for the year. It is the rear-size choice to confirm when a DB7 is equipped with the 19-inch wheel combination.
Year(s): 2004|Fit(s): DB7|Construction: Radial|Rim: 18 in
265/35R18 is a metric radial size with a 265-millimeter section width, a 35-series aspect ratio, and fitment for an 18-inch wheel. BFGoodrich and Nitto offer this size in blackwall form, and speed ratings vary by product, with W reaching 168 mph and Y reaching 186 mph or higher. This size is specific to the DB7 and serves the 18-inch rear application rather than every 2004 Aston Martin model. It is the rear-size match for DB7 owners confirming an 18-inch front-and-rear package.
Year(s): 2004|Fit(s): Vanquish|Construction: Radial|Rim: 19 in
255/40R19 is a metric radial size with a 255-millimeter section width, a 40-series aspect ratio, and fitment for a 19-inch wheel. BFGoodrich covers this size in blackwall form, and speed ratings vary by product, with W reaching 168 mph and Y reaching 186 mph or higher. This size is specific to the Vanquish and is not shared with the DB7. It fits the front position on the Vanquish's 19-inch staggered setup and should be matched carefully to the corresponding rear size.
285/40R19 is a metric radial size with a 285-millimeter section width, a 40-series aspect ratio, and fitment for a 19-inch wheel. Blackwall radial choices define this size category for the 2004 Aston Martin Vanquish. This size is specific to the Vanquish and serves the rear of that model's staggered 19-inch arrangement rather than the full Aston Martin lineup for the year. It is the size to verify when maintaining the Vanquish's original front-to-rear width relationship.
Two Aston Martin models are covered for 2004. Tire size changes by model, and in the DB7's case it also changes by wheel package, so identifying the exact model matters before choosing a tire. Select a model below to narrow the fitment history and see the sizes that apply to that specific Aston Martin.
2004 Aston Martin DB7
The 2004 Aston Martin DB7 carried the elegant Ian Callum-era shape that helped define Aston Martin's modern revival, blending traditional grand touring style with contemporary performance. Its tires mount on either 18-inch or 19-inch wheels depending on the setup, with staggered front and rear sizes in both cases. That makes wheel-diameter confirmation especially important before choosing a tire for a DB7.
The 2004 Aston Martin Vanquish was the marque's flagship grand tourer, pairing dramatic styling with a more assertive, high-speed character than the DB7. Its tires mount on 19-inch wheels front and rear, using a wider rear size than the front in a classic staggered performance layout. Keeping the correct front-to-rear size relationship is central to choosing tires for a Vanquish.
Twenty products are available across six tire sizes for 2004 Aston Martin vehicles. The 245/35R19 has 3 BFGoodrich and Nitto blackwall radials, 245/40R18 has 7 M&H Racemaster, BFGoodrich, and Nitto blackwall radials, 265/35R18 has 4 BFGoodrich and Nitto blackwall radials, and 255/40R19 has 6 BFGoodrich blackwall radials. Confirm your size first, since speed ratings can vary within some sizes.
These answers focus on the model-specific sizing differences between the 2004 Aston Martin DB7 and Vanquish, how the 18- and 19-inch fitments relate, and what to check on modern radial performance tires before fitting a low-use collector car.
Size Basics & Fitment
What tire sizes fit 2004 Aston Martin vehicles?
2004 Aston Martin vehicles use six sizes, and they are model-specific rather than shared across the whole range. The DB7 uses 245/40R18 and 265/35R18 on its 18-inch setup, or 245/35R19 and 265/30R19 on its 19-inch setup. The Vanquish uses 255/40R19 at the front and 285/40R19 at the rear. Rim-width guidance appears where available: 245/35R19 fits 8.0 to 9.5-inch rims, 245/40R18 fits roughly 8.0 to 9.5-inch rims, 265/35R18 fits 9.0 to 10.5-inch rims, and 255/40R19 fits 8.5 to 10.0-inch rims.
The practical takeaway is that year and make alone are not enough for a 2004 Aston Martin. You need to identify whether the car is a DB7 or a Vanquish, then confirm whether the DB7 is on its 18-inch or 19-inch wheel package. After that, verify front and rear sizes separately, because both models use staggered sizing and the rear tire is not interchangeable with the front.
What does 245/35R19 mean on a 2004 Aston Martin tire?
On a 2004 Aston Martin, 245/35R19 is a metric radial size. The 245 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. In 2004 Aston Martin applications, this size belongs to the DB7 and mounts on a 19-inch wheel, with rim-width guidance running from 8.0 to 9.5 inches on the available products.
That breakdown matters because it tells you this is not just any 19-inch tire. The width, sidewall height, and radial construction are all part of the intended fitment, and changing one dimension can alter stance, clearance, and front-to-rear balance. If your DB7 wears 19-inch wheels, confirm whether 245/35R19 is the front size before choosing among the available blackwall performance radials.
Do all 2004 Aston Martin models use the same tire size?
No, 2004 Aston Martin models do not use the same tire size. The DB7 has four possible sizes because it appears with either an 18-inch or a 19-inch staggered setup, while the Vanquish uses its own 19-inch staggered pair in 255/40R19 front and 285/40R19 rear. Every size in this year and make is a radial, but the actual measurements differ enough that cross-model substitution should not be assumed.
For a buyer, that means the model badge is the first checkpoint and the wheel diameter is the second. A DB7 owner who skips that step can easily land on a tire meant for the other DB7 wheel package, and a Vanquish owner can mistake a 19-inch DB7 size for a correct fit just because the rim diameter matches. Confirm the exact front and rear sizes on the car before moving ahead.
Buying the Right Tire
What sidewall styles are available for 2004 Aston Martin tires?
The available 2004 Aston Martin tires in these sizes use blackwall sidewalls across the sizes with product coverage. That suits the period and character of both the DB7 and Vanquish, since these are modern-era high-performance grand touring Aston Martins rather than wide-whitewall classics. The blackwall presentation also aligns with the low-profile radial sizing used on these cars.
From a buying standpoint, sidewall style is less of a branching decision here than size, model, and speed category. Once you have confirmed the correct front and rear dimensions, the main differences shift to brand, series, rim-width compatibility, and speed letter. That keeps the visual appearance consistent while allowing you to choose the product line that best matches how the car is driven.
What brands make tires for 2004 Aston Martin vehicles?
Three brands cover the 2004 Aston Martin sizes shown here: BFGoodrich, Nitto, and M&H Racemaster. BFGoodrich and Nitto appear in the 245/35R19, 245/40R18, and 265/35R18 sizes, while BFGoodrich alone appears in 255/40R19, and M&H Racemaster appears in 245/40R18. The overall mix is strongly performance-oriented, which fits the DB7 and Vanquish character well.
Brand choice should come after fitment is settled, not before. Start by confirming the exact front and rear sizes on your model, then compare the brands available within those sizes. Once you are inside the correct size, details such as speed rating, rim-width range, and the product line's intended use become more important than simply picking a familiar brand name.
What is the difference between BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Phenom T/A for a 2004 Aston Martin?
Within overlapping 2004 Aston Martin sizes, BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Phenom T/A share blackwall radial construction but differ in available speed letters and some published load figures. In 245/35R19, the Comp 2 A/S appears as 93W and the Phenom T/A also appears as 93W, with the Phenom carrying a published load figure of 1,433 pounds at 50 psi. In 265/35R18, the Comp 2 A/S appears as 97W while the Phenom T/A appears as 97Y with 1,609 pounds at 50 psi.
That means the choice is less about basic fitment and more about the exact spec you want inside the same size. If your car calls for 265/35R18, for example, the W-versus-Y distinction may matter to owners who want to stay closer to a particular speed category. It is smart to compare the full sidewall marking and load information on the exact tire before making a final decision.
Fitting & Setup
What rim width do 2004 Aston Martin tires require?
Rim-width guidance varies by size on 2004 Aston Martin applications. The 245/35R19 fits 8.0 to 9.5-inch rims, 245/40R18 fits about 8.0 to 9.5 inches depending on product, 265/35R18 fits 9.0 to 10.5-inch rims, and 255/40R19 fits 8.5 to 10.0-inch rims. Those ranges align with the front-versus-rear stagger seen on both the DB7 and Vanquish, where the wider rear tire generally belongs on a wider wheel.
Rim width is one of the easiest fitment details to overlook when replacing tires on a collector-performance car. Even if the diameter and size code look right, the tire still needs to suit the wheel's actual width to maintain proper shape and behavior. Measure the wheels already on the car or confirm their specifications before selecting a tire, especially if the car may have been changed from its original setup.
Do 2004 Aston Martin tires require inner tubes?
The 2004 Aston Martin sizes shown here are modern radial performance sizes, and one 255/40R19 application is explicitly marked TL for tubeless. Other size markings do not consistently call out tube status in the same way, so the safest reading is to treat tubeless fitment as common for this era and confirm the exact sidewall marking on the specific tire you choose. Wheel design and condition still matter, especially on older wheels that may have been refinished or repaired.
In practice, the tire alone is only part of the tube question. If your wheels are original, inspect the bead seats, valve stem condition, and general sealing surfaces before mounting new tires. A tire installer familiar with performance and collector cars can help confirm whether the wheel is suitable for tubeless service in its present condition rather than assuming every 19-inch or 18-inch wheel behaves the same.
Maintenance, Storage & Longevity
How should I store a 2004 Aston Martin when the tires are fitted?
A 2004 Aston Martin should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that can age rubber prematurely. Keep the tires properly inflated, avoid long exposure to moisture on bare concrete, and move the car periodically if it sits for extended stretches. Low-profile radial tires generally tolerate storage better than older bias-ply designs, but they still benefit from careful environmental control.
Owners who keep a DB7 or Vanquish off the road for part of the year should think about tire condition as part of overall preservation, not just appearance. If the car will sit for months, occasional rolling or the use of stands can help reduce flat spotting and stress at one contact patch. A clean, climate-stable garage does more for tire longevity than any dressing or cosmetic treatment.
How long do tires on a 2004 Aston Martin typically last?
On a 2004 Aston Martin, tire age usually matters more than mileage because many DB7 and Vanquish cars are driven sparingly. A sound rule is to begin close inspection once tires reach about five to seven years of age and to treat around ten years as the point where replacement deserves serious consideration, regardless of remaining tread. The DOT date code on the sidewall is the simplest way to determine a tire's age.
Collector cars often wear tires that look fresh but have aged internally from time, heat cycles, and storage conditions. That is especially important on powerful grand touring cars, where high-speed stability depends on healthy sidewalls and consistent construction. If your Aston Martin still wears older tires, judge them by age and condition first, not by how many miles the odometer says the car has traveled.
How often should tires on a 2004 Aston Martin be inspected?
Tires on a 2004 Aston Martin should be inspected before every drive and again before any longer trip. Look for sidewall cracking, punctures, bulges, uneven shoulder wear, embedded debris, and any sign that the tire has been run underinflated. Because both the DB7 and Vanquish use staggered sizing, it is also worth confirming that the correct front and rear tires remain in their intended positions after any recent service.
A quick walkaround can prevent problems that do not show up until the car is fully warm and up to speed. Check air pressure when the tires are cold, and pay attention to steering feel or vibration once underway, since those can be early clues to a tire issue. If a tire loses pressure over time, inspect the valve stem and the wheel sealing surfaces as part of the diagnosis.
Safety & Road Use
Are 2004 Aston Martin tires safe for highway driving?
Yes, the radial tires available for 2004 Aston Martin sizes are suitable for highway use when the correct size, condition, and inflation are maintained. Speed ratings in these sizes include W, which carries a 168 mph ceiling, and Y, which carries a 186 mph-or-higher ceiling. Those numbers are well beyond normal U.S. highway speeds, so on a sound DB7 or Vanquish the larger real-world limits are often tire age, inflation, alignment, and the overall mechanical condition of the car.
Highway safety is not just about the letter on the sidewall. A high-speed-rated tire that is old, damaged, or mounted on the wrong wheel is still a poor choice. Before any extended highway run, confirm the tire size, inspect the sidewalls and tread carefully, and make sure the suspension, brakes, and steering are in equally good order so the car can use the tire's capability properly.
What inflation pressure should I use for 2004 Aston Martin tires?
Inflation pressure for a 2004 Aston Martin should start with the factory recommendation for the exact model and wheel setup, then be checked against the maximum load-and-pressure information printed on the tire itself. Available examples include 245/35R19 at 1,433 pounds at 50 psi, 245/40R18 from 1,235 pounds at 44 psi up to 1,609 pounds at 50 psi, 265/35R18 at 1,433 pounds at 51 psi or 1,609 pounds at 50 psi, and 255/40R19 at 1,764 pounds at 50 psi.
Those figures are not blanket running pressures for every Aston Martin application. They describe the tire's rated capacity at a stated pressure and should not be transferred from one size to another or from one model to another. Use the car's recommended cold pressure as your baseline, then fine-tune only within the tire maker's guidance and the needs of the car's actual wheel-and-tire combination.
What should I check before taking a 2004 Aston Martin on a longer drive?
Before a longer drive in a 2004 Aston Martin, inspect each tire for cracks, cuts, punctures, bulges, unusual wear, and correct cold pressure. Confirm that the front and rear sizes match the car's staggered setup, and examine the valve stems as closely as the tread. If the car carries a spare or mobility solution, check that as well, because a grand touring route can quickly become inconvenient if the backup is neglected.
Tires are only one part of the pre-trip routine on a DB7 or Vanquish, but they are the part that touches the road every mile. Once the tires pass inspection, give equal attention to brakes, fluids, steering feel, and wheel fastener torque. A well-prepared Aston Martin is far more enjoyable on a longer run, and tire confidence is a big part of that confidence behind the wheel.
