1995 Aston Martin Tire Fitment Guide

1995 Aston Martin vehicles use two tire sizes, and both apply to the DB7. The front size is 245/40R18 and the rear size is 265/35R18, so this is a staggered setup rather than a same-size arrangement at all four corners. Both sizes mount on 18-inch wheels. Rim-width coverage runs from 8.0 to 9.5 inches for most 245/40R18 road tires, with one 245 fitment at 8.5 inches, while 265/35R18 road tires span 9.0 to 10.5 inches.

That means the first fitment question on a 1995 Aston Martin is not simply year and make, but which end of the DB7 you are replacing. If you are changing only two tires, confirm whether you need the narrower front or wider rear size. If you are restoring or servicing a full set, verify the wheel widths on the car before final selection so the tire matches both the position and the wheel it will be mounted on.

On a 1995 Aston Martin DB7, 245/40R18 is a modern metric radial size. The 245 is the nominal section width in millimeters, 40 is the aspect ratio, meaning the sidewall height is 40 percent of the section width, R identifies radial construction, and 18 is the wheel diameter in inches. In this application, it is the front tire size and is paired with blackwall radial products from M&H Racemaster, BFGoodrich, and Nitto.

Understanding that code helps you separate road-use tires from specialized products in the same basic size. A DB7 owner looking for front tires can stay within the correct size while still choosing between general performance street radials and a drag-oriented radial. That keeps the fitment right while letting the tire's intended use guide the final decision.

On a 1995 Aston Martin DB7, 265/35R18 is also a metric radial size. The 265 is the nominal section width in millimeters, 35 is the aspect ratio, R means radial construction, and 18 is the wheel diameter in inches. In the DB7 fitment, this is the rear size, and it appears in blackwall radial form from BFGoodrich and Nitto with W- and Y-rated choices depending on the tire.

That larger rear size is part of the DB7's staggered layout, so it should not be treated as an interchangeable alternative to the front size. If you are replacing rear tires, match the 265/35R18 size and confirm the wheel width before mounting. Keeping the rear fitment correct preserves the car's intended stance and avoids mixing front and rear sizes by mistake.

A 1995 Aston Martin DB7 does not call for one size or the other as a preference choice; it uses both. The 245/40R18 is the front fitment and the 265/35R18 is the rear fitment, so the decision is based on tire position rather than style or construction, since both sizes are radial and both mount on 18-inch wheels. Choosing between them starts with identifying which axle you are servicing.

If you are replacing a full set, order both sizes as a matched front-and-rear combination. If you are replacing only two tires, verify whether the car needs fronts or rears and check the wheel widths already on the car. That step matters more on a staggered grand touring car than broad year-make lookups, because the wrong size can be correct for the model yet still be wrong for the end of the car.

1995 Aston Martin DB7 tires in these two sizes are available in blackwall form. The 245/40R18 and 265/35R18 both stay within a modern performance appearance rather than using wide whitewall, redline, or other vintage decorative sidewall treatments. That suits the DB7's 1990s design language, which was far more contemporary than earlier Aston Martins and visually belongs with low-profile radial tires.

For most owners, that makes the sidewall decision straightforward: choose the tire based on intended use, speed rating, and wheel fit rather than visual trim. If originality of overall appearance matters, a blackwall radial is the natural match for a 1995 Aston Martin. The finer point is selecting the right front and rear sizes rather than searching for an era-style sidewall treatment that was never central to the car's look.

Three brands cover 1995 Aston Martin DB7 tire sizes: BFGoodrich, Nitto, and M&H Racemaster. The 245/40R18 front size is available from all three, while the 265/35R18 rear size is available from BFGoodrich and Nitto. Within BFGoodrich, the DB7 sizes are represented by more than one performance series, which gives owners a few ways to stay within the correct fitment while choosing a tire character that fits the car's use.

That brand spread is most useful when you already know whether you need a front or rear tire. A driver-focused DB7 may lean toward mainstream performance street radials, while a specialized straight-line use case points toward the drag-oriented 245/40R18 option. The important thing is to compare within the correct size first, then sort by brand, service description, and speed rating.

For 1995 Aston Martin DB7 fitment, 245/40R18 road tires fit rim widths from 8.0 to 9.5 inches, with one 245 application built around an 8.5-inch wheel. The 265/35R18 rear size fits 9.0 to 10.5 inches. Both sizes share an 18-inch rim diameter, but the front and rear width ranges are different because the rear tire is substantially wider.

That makes wheel-width confirmation especially important if the car has aftermarket wheels or if you are replacing tires after years of prior ownership changes. A tire can have the right diameter and still be a poor match for the wheel if the width is off. Check the wheel itself before final selection so the front tire matches a front-width wheel and the rear tire matches a rear-width wheel.

The 1995 Aston Martin DB7 tire options here are modern radial performance tires, and tube-type markings are not part of these size descriptions. That points to a tubeless-style fitment rather than a classic tube-type setup. Nothing in these DB7 sizes suggests the kind of antique or early bias-ply application where an inner tube would normally be expected as part of the standard package.

Even so, the wheel still matters. If a DB7 is wearing original-style 18-inch wheels in sound condition, the usual path is a tubeless radial installation with proper valve stems and a clean bead seat. If the wheels have been repaired, modified, or heavily refinished, have them inspected during mounting so air retention depends on the wheel's condition as much as the tire itself.

A 1995 Aston Martin DB7 uses 18-inch wheels front and rear, so both 245/40R18 and 265/35R18 share the same wheel diameter. That means the original wheels can support both sizes in the sense of diameter compatibility, but not as interchangeable front-to-rear pieces without checking width. The front tire's rim-width range is narrower than the rear tire's, which reflects the car's staggered layout.

In practice, the original wheel diameter is not the issue; wheel width and position are. A front wheel intended for 245/40R18 should not automatically be treated as suitable for the 265/35R18 rear size, and the reverse is equally true. If you are rotating wheels for service work or sorting through spare parts, confirm which wheel belongs at which corner before mounting tires.

A 1995 Aston Martin DB7 stores best in a cool, dry garage away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate sidewall aging. Keep the tires properly inflated during storage and avoid leaving the car parked for long periods on a damp surface. Because the DB7 uses low-profile radial tires, regular movement helps reduce flat-spotting and keeps the tires from sitting under load in one position for too long.

If the car will sit for months at a time, rolling it periodically or using stands under the suspension can help reduce long-term stress. Storage habits matter as much as mileage on collector GT cars, because a tire can age out while still showing substantial tread. A clean, climate-stable space is one of the simplest ways to preserve both the tires and the overall driving feel of the car.

On a 1995 Aston Martin DB7, tire life should be judged more by age and condition than by mileage alone. A collector-driven car may cover few miles while the rubber still hardens over time, so five to seven years is a sensible evaluation window and around ten years is a common point for serious replacement consideration regardless of tread depth. The DOT date code on the tire sidewall is the key reference for age.

That approach is especially important on a performance-oriented 1990s grand tourer, where grip, ride quality, and wet-weather behavior can decline before the tread looks worn out. If a DB7 has older tires with plenty of visible tread, inspect them with the same seriousness you would apply to a heavily driven set. Age, cracking, and loss of compliance are what usually retire collector-car tires first.

Tires on a 1995 Aston Martin DB7 should be inspected before every drive and again before any longer outing or tour. Look for sidewall cracking, punctures, bulges, uneven wear, and any sign that a tire is losing pressure. On a staggered setup, check all four corners individually rather than assuming front and rear wear or condition will match, because the tire sizes and wheel widths differ.

That routine matters even more on a car that is driven intermittently. A DB7 can sit long enough for age-related issues to develop quietly, then be asked to cruise at modern highway speeds the next day. Frequent visual inspection, regular pressure checks, and periodic professional evaluation give you a much better chance of catching a problem before it turns into vibration, poor handling, or a roadside failure.

Yes, the 1995 Aston Martin DB7 tire options in these sizes are modern radial performance tires appropriate for highway use when they are in good condition and matched to the correct wheel. Within these sizes, W-rated tires carry a 168 mph ceiling and Y-rated tires carry a 186 mph-plus ceiling. Those ratings are far beyond ordinary interstate use, and on a grand touring car of this era, overall mechanical condition often matters more in real-world touring than the tire's top-speed symbol alone.

Safety on the road still depends on age, inflation, alignment, and whether the front and rear sizes are mounted in the proper positions. A newer W-rated or Y-rated tire that fits correctly is a far better highway companion than an old tire with more impressive numbers on paper. Treat speed rating as one part of the picture, then inspect the entire car before expecting it to perform confidently on a long drive.

Inflation pressure on a 1995 Aston Martin DB7 should follow the vehicle's factory recommendation first, since the car uses a staggered setup and front and rear needs may differ. Tire load-and-pressure figures in these sizes include 245/40R18 examples at 1,235 pounds at 44 psi, 1,433 pounds at 51 psi, and 1,609 pounds at 50 psi, while 265/35R18 examples include 1,433 pounds at 51 psi and 1,609 pounds at 50 psi. Those are maximum load-at-pressure ratings for the tire itself, not a blanket setting for every DB7.

The practical approach is to use the Aston Martin specification as your baseline, then make sure the chosen tire is suitable for that service. Do not transfer a pressure number from the front size to the rear size or from one product line to another just because the wheel diameter matches. If the car has aftermarket wheels or suspension changes, revisit pressures carefully after confirming the fitment is otherwise correct.

Before a longer drive in a 1995 Aston Martin DB7, inspect all four tires for cracking, cuts, punctures, bulges, and uneven wear, then confirm cold pressures at each corner. Make sure the front 245/40R18 and rear 265/35R18 positions are correct, and check the spare if the car carries one. Because the DB7 is a performance GT car, a tire issue that seems minor around town can become very noticeable at sustained highway speeds.

That tire check should be part of a broader pre-drive routine that includes brakes, fluids, suspension condition, and steering feel. On an older grand tourer, the tires are the final link between all of those systems and the road. A careful inspection before departure is less about ceremony and more about preserving the smooth, confident character that made the DB7 appealing in the first place.
