Bentley Arnage Tires

Bentley Arnage uses four tire sizes across its 1999 to 2009 production run: 255/55R17 for 1999, 255/50R18 for 2000 through 2009, 255/45R19 for 2002 through 2009, and 255/40R20 for 2009. Each size is tied to a specific wheel diameter, so those fitments correspond to 17-inch, 18-inch, 19-inch, and 20-inch wheels respectively.

The practical step is to confirm the wheel diameter actually fitted to your Bentley Arnage before choosing a tire, then match the size to the correct year range. That matters most on later cars, where one model year can carry more than one wheel and tire package.

On a Bentley Arnage, 255/50R18 is a modern metric radial size. The 255 is the section width in millimeters, the 50 is the aspect ratio as a percentage of that width, the R means radial construction, and the 18 is the wheel diameter in inches.

Reading the code correctly helps you avoid one of the most common mistakes on modern luxury cars: matching width but missing the wheel diameter or profile. A Bentley Arnage that needs 255/50R18 must remain on an 18-inch wheel, even if another year of Arnage used a tire with the same width on a different diameter rim.

The 2009 Bentley Arnage appears with 255/50R18, 255/45R19, and 255/40R20 because that model year includes a rim-diameter split rather than one universal tire package. All three sizes share the same 255 mm nominal width, but each is built around a different wheel diameter and sidewall profile.

That means year alone is not enough to choose correctly for a 2009 Bentley Arnage. Check the wheel itself, confirm whether the car is on 18-inch, 19-inch, or 20-inch rims, and then match the tire size to that wheel diameter before moving ahead.

Bentley Arnage uses several rim diameters across its production run: 17 inches in 1999, 18 inches from 2000 onward, 19 inches from 2002 onward on certain configurations, and 20 inches in 2009 on one listed fitment. The first wheel-diameter change occurs in 2000, when the model moves from 17-inch to 18-inch fitment.

Wheel diameter is the first specification to verify because it immediately narrows the correct tire family. Once you know whether your Bentley Arnage is on 17-, 18-, 19-, or 20-inch wheels, the year listing becomes much easier to use accurately.

Start with the model year, then match it to the tire sizes assigned to that Bentley Arnage year: 1999 uses 255/55R17, 2000 and 2001 use 255/50R18, 2002 through 2008 can use either 255/50R18 or 255/45R19, and 2009 can use 255/50R18, 255/45R19, or 255/40R20. The deciding factor on years with multiple options is the actual wheel diameter fitted to the car.

Inspect the wheel, confirm its diameter, and compare the mounted tire size if the car already has tires installed. On a Bentley Arnage, that simple check prevents ordering a 19-inch or 20-inch fitment for a car still carrying 18-inch wheels.

The currently listed Bentley Arnage product offering shows a Blackwall sidewall style in 255/40ZR20. No additional sidewall styles appear in the available product range tied to this model group.

For a late-production luxury sedan like Bentley Arnage, blackwall styling is visually appropriate and consistent with modern high-performance radial presentation. If your car uses a different wheel diameter than the listed 20-inch product, match size and wheel fitment first, then consider sidewall appearance within the correct size category.

The current Bentley Arnage product coverage includes BFGoodrich. The listed product is the g-Force Phenom T/A in 255/40ZR20.

Brand choice matters less than getting the correct size and wheel diameter for your specific Bentley Arnage year and configuration. Once that fitment is confirmed, you can evaluate the available brand by its construction type, load rating, sidewall style, and intended character.

The listed Bentley Arnage product range currently includes the BFGoodrich g-Force Phenom T/A series. It is a modern radial performance tire and is shown in 255/40ZR20 sizing for the 20-inch Arnage application.

For a Bentley Arnage, tire series differences matter because they shape how the car feels on the road as much as the raw size does. If your Arnage uses another wheel diameter, keep the size and rim match as the priority, then compare available series within that correct fitment group.

A Bentley Arnage should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and prolonged heat. Inflation should be kept at an appropriate level for storage, and the car should not be left sitting for long periods with visibly low tires carrying the vehicle’s full weight.

Because Bentley Arnage is a heavy luxury sedan, flat spotting and sidewall stress can develop faster than on lighter collector cars. Rolling the car periodically, using tire cradles, or supporting the car properly during long-term storage helps preserve the tire shape and reduce standing-load damage.

Tires on a Bentley Arnage should be inspected before any meaningful drive and at regular intervals even when the car is used sparingly. Look for cracking, bulges, irregular wear, impact damage, valve-stem deterioration, and any mismatch between the tire size fitted and the wheel diameter the car actually carries.

Collector cars often age their tires out before they wear them out, and Bentley Arnage is no exception. Frequent visual checks, pressure checks, and occasional professional inspection are especially worthwhile on a large, powerful sedan that can place significant stress on aging tires.

Tires on a Bentley Arnage should be replaced when they show age cracking, hardening, sidewall distortion, repeated air loss, impact damage, or any structural concern, even if the tread still appears usable. Tread depth alone is not a reliable measure of serviceability on a collector car that may spend much of its life parked.

The safest approach is to treat age and condition as seriously as wear, particularly on a heavy car like Bentley Arnage. If a tire’s history is uncertain or its condition raises questions, replacement is the better path than continuing to rely on appearance alone.

Bentley Arnage appears with four production-era size families across its run: 255/55R17 in 1999, 255/50R18 from 2000 onward, 255/45R19 from 2002 onward, and 255/40R20 in 2009. Those size changes reflect the model’s evolution through different wheel packages during production rather than a single universal original fitment.

For restoration accuracy, the best reference is the exact year and configuration of your Bentley Arnage, then the wheel diameter actually fitted to the car. Matching the correct size for that specific setup supports the proper stance and preserves the visual character expected of a flagship Bentley saloon.

Correct tire fitment can affect how a Bentley Arnage is viewed, especially when the car is presented as a carefully preserved or accurately restored example. The right size and wheel-diameter combination helps maintain proper proportions, fills the arches correctly, and supports the model’s intended visual presence.

For owners concerned with presentation, originality, or marque scrutiny, tire fitment should match the specific year and wheel package rather than a convenient substitute. A Bentley Arnage wearing the wrong diameter or profile can look subtly off even before any mechanical concerns are considered.

The current Bentley Arnage product offering shows a Blackwall sidewall style. That appearance suits the late-classic to modern character of the Arnage and aligns well with the restrained, performance-oriented presentation expected on a large luxury sedan from this era.

If your restoration goal is factory-like visual correctness, begin with the proper tire size and wheel diameter, then evaluate sidewall styling within that fitment. On Bentley Arnage, the sidewall profile and wheel proportion usually have a bigger effect on authenticity than decorative sidewall treatment.

A Bentley Arnage can be driven on public roads when it is fitted with the correct tire size for its wheel diameter and the tires are in sound condition. Safe road use depends on much more than tread depth, including age, load suitability, inflation condition, and freedom from cracking or structural damage.

Because Bentley Arnage is a heavy, high-performance luxury car, any weakness in tire condition is magnified in use. Before regular road driving, make sure the tire size matches the wheel exactly and have any aging or questionable tire evaluated by a qualified tire professional.

Before driving a Bentley Arnage, check that all four tires match the wheel diameter they are mounted on, inspect for visible cracking or bulges, confirm inflation, and look for uneven wear that could point to alignment or suspension issues. Also verify that the tire size on the car matches one of the appropriate Bentley Arnage fitments for its year and wheel package.

That pre-drive inspection is especially important on collector-use cars that may sit for long stretches between outings. A few minutes spent checking tire condition can catch age-related problems early and help prevent a roadside failure in a car that places substantial load on its tires.

Appropriate speed for a Bentley Arnage on its tires should be governed by the exact tire fitted, its condition, and its service age rather than the car’s performance capability alone. Even when the size is correct, an older tire should not be treated like a fresh high-speed-rated modern tire simply because the vehicle itself is capable of substantial speed.

The sensible approach is to drive a Bentley Arnage progressively and conservatively until tire condition, age, and overall readiness are fully known. On any collector car, preserving a margin of safety matters more than testing the theoretical limits suggested by the size code.
