Bentley Azure Tires

Bentley Azure uses five tire sizes across the years covered here: 255/55R17 for 1996-2002, 255/50R18 for 1998-2002, 285/45R18 for 1999-2003, 255/45R19 for 2006-2009, and 255/40R20 for 2009-2010. Their rim diameters are built into the size codes, so those fit 17-inch, 18-inch, 18-inch, 19-inch, and 20-inch wheels respectively.

The important detail is that some Bentley Azure years overlap multiple sizes rather than using one size across the board. A 1999 through 2002 car, and especially a 2009 car, should be checked by actual wheel diameter and current tire markings instead of relying on year alone.

A 1999 Bentley Azure shows three listed sizes because that year sits in a transition period. The available sizes are 255/55R17, 255/50R18, and 285/45R18, which means both 17-inch and 18-inch wheel fitments appear, along with two different widths on the 18-inch wheel.

That makes 1999 a configuration-sensitive year rather than a simple one-size year. The correct approach is to confirm whether the car carries 17-inch or 18-inch wheels first, then determine whether the 18-inch setup uses the narrower 255 section width or the wider 285 section width.

Bentley Azure uses several rim diameters across its production span: 17-inch, 18-inch, 19-inch, and 20-inch. The earliest cars use 17-inch fitments, 18-inch sizes begin in 1998, 19-inch fitments appear in 2006, and 20-inch fitments arrive in 2009.

Rim diameter is the first fitment point to verify because none of these sizes interchange across different wheel diameters. Reading the tire sidewall and measuring the wheel if needed will usually settle the question faster than working from model year alone.

On a Bentley Azure, 255/40R20 means the tire is 255 millimeters wide, has a 40-series aspect ratio, uses radial construction, and fits a 20-inch wheel. The available product in this size is shown with a recommended rim-width range of 8.5 to 10 inches.

That size belongs to late Bentley Azure fitment, covering 2009 and 2010, and it should only be used on cars equipped with the matching 20-inch wheel. On a 2009 Bentley Azure, this matters especially because that same year also appears with a 19-inch alternative.

A 2000 Bentley Azure can use 255/55R17, 255/50R18, or 285/45R18, so the year by itself does not settle the question. The correct tire size comes down to the wheel diameter on the car and, for 18-inch applications, whether the setup uses the narrower or wider section width.

Start with the tire currently mounted and the wheel diameter cast or stamped on the wheel, then compare that information to the year listing. If the car is being restored or returned to a prior wheel package, original service records or marque-specific references are the best way to confirm the intended fitment.

The currently listed Bentley Azure product is from BFGoodrich. It appears in the 255/40R20 size with the g-Force Phenom T/A series and radial construction.

Because the available product coverage shown here is limited to one size, brand availability should not be assumed across the full Bentley Azure year range. Match the exact size first, then compare the tire's dimensions and approved rim-width range to the wheels fitted to the car.

The listed Bentley Azure product appears in the BFGoodrich g-Force Phenom T/A series. That is a modern radial performance tire line, and the shown 255/40ZR20 version uses a 20-inch rim and carries a 101Y service description.

For a late Bentley Azure, the tire series matters because it reflects the kind of driving character the tire is designed to support, not just the raw size. Even when the size matches, the wheel-width range, load capability, and overall intent of the tire should align with the specific car and its wheel setup.

A Bentley Azure should be stored on clean, properly inflated tires in a cool, dry, dark space away from direct sunlight, ozone sources, and long periods of heat exposure. Heavy luxury convertibles place meaningful static load on their tires, so storage conditions matter even when the car is driven only occasionally.

If the car will sit for extended periods, move it periodically or use appropriate supports to reduce flat-spotting and sidewall stress. Keeping the tires clean, the pressures consistent, and the car out of harsh environmental conditions will do more for tire life than mileage alone on a low-use collector Bentley Azure.

Tires on a Bentley Azure should be inspected regularly for pressure loss, sidewall cracking, tread irregularity, impact damage, and age-related hardening. A low-mile collector car can still develop tire problems because time, load, and storage conditions affect rubber even when tread wear remains minimal.

A practical routine is to inspect the tires before each drive and give them a more thorough check several times a year, especially before highway use or seasonal outings. Uneven wear or repeated pressure changes can also point to wheel, alignment, or suspension issues that should be corrected before the next drive.

Bentley Azure tires should be replaced when they show age cracking, sidewall deterioration, tread separation, impact damage, persistent vibration, or hardening that changes the way the car rides and responds, even if tread depth still looks acceptable. Collector cars often age out tires before they wear them out.

The decision should be driven by condition and age as much as mileage, especially on a substantial grand touring convertible that can stress old rubber. Any tire of uncertain age or history deserves careful evaluation before continued road use, because appearance alone does not tell the full story.

Bentley Azure appears with several original-style fitment sizes across its run rather than one size for every year. The range begins with 255/55R17, then expands to 255/50R18 and 285/45R18, later moves to 255/45R19, and finally to 255/40R20.

For restoration work, the correct answer depends on the exact production year and the wheel package fitted to the individual Bentley Azure. Factory literature, service history, and marque-specific references are the right way to confirm whether the car should retain its present wheel and tire specification or return to an earlier configuration.

Correct tire fitment can affect both presentation and credibility on a Bentley Azure, especially when wheel diameter and tire proportions are a visible part of the car's stance. A car wearing the wrong diameter or an incorrect width relationship can look noticeably different from its intended configuration.

For judged events or high-level restoration, getting the year-appropriate size and wheel package right is more important than simply finding a tire that physically fits. Owners seeking maximum authenticity should compare the car against factory references and marque-club guidance before finalizing a restoration-era tire choice.

The currently listed Bentley Azure tire is offered as a Blackwall. That sidewall style suits the late-production 255/40R20 application shown here and aligns with the modern performance-oriented appearance expected on a high-end convertible from this era.

For restoration purposes, sidewall style should follow the exact year, wheel package, and visual character of the car rather than personal preference alone. A Bentley Azure restored to later production appearance generally benefits from a restrained blackwall presentation that does not overpower the wheel design.

A Bentley Azure can be driven on public roads safely when the tires are the correct size for the wheel, are in sound condition, and are appropriate for the weight and intended road use of the car. The listed 255/40R20 product is a modern radial with a 101Y service description and a maximum load rating of 1819 pounds at 50 psi.

Road safety depends on more than size alone, so condition, age, inflation, alignment, and suspension health all matter. On a Bentley Azure, using the wrong wheel diameter or an aged tire with deteriorated structure can undermine handling and braking even if the tread still appears usable.

Before driving a Bentley Azure, check tire pressure, sidewall condition, tread condition, wheel damage, and any signs of vibration or flat-spotting from storage. Because this model spans several wheel diameters and overlapping sizes, it is also wise to confirm that all four tires match the intended fitment for the car.

A brief pre-drive check is especially worthwhile on low-mile collector cars that may sit for long periods between outings. If the car pulls, shimmies, or feels unsettled once underway, stop and inspect the tires and wheels before continuing at normal road speeds.

A Bentley Azure should only be driven at speeds appropriate to the condition, age, and capability of the tires actually fitted to the car. For the listed 255/40R20 radial, the 101Y service description indicates a modern high-speed-capable tire, but that rating only matters when the tire is in proper condition and correctly fitted to the wheel.

On any collector Bentley Azure, sensible road speed should reflect the entire vehicle, not the printed rating alone. Tire age, storage history, inflation, suspension condition, and overall mechanical health should all be considered before using the car at sustained highway or high-speed touring pace.
