The 2009 Bentley Arnage represents the final era of Bentley’s hand-built flagship sedan, blending traditional British luxury with the presence and power expected from a large, chauffeur-worthy grand touring car. On a vehicle of this size and character, tire fitment is less about guesswork and more about confirming the exact Arnage sub-model and wheel diameter first. Depending on configuration, the 2009 Bentley Arnage uses 255/50R18, 255/45R19, or 255/40R20 radial tires. That makes the real choice a matter of matching the correct wheel setup, then selecting the right tire style and specification for road use, appearance, and overall driving intent.
Which Tire Size Is Right for The 2009 Bentley Arnage
The 2009 Bentley Arnage uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are radial metric sizes, but they are tied to different 18-inch, 19-inch, and 20-inch wheel fitments. The first step is confirming which Arnage version you have and which wheels are actually on the car before comparing tire choices.
A 255/40R20 tire uses a 255-millimeter section width, a 40-series aspect ratio, radial construction, and a 20-inch rim. On the 2009 Bentley Arnage, this size is associated with the Final Series and reflects a lower-profile modern luxury-performance fitment. Available product choice in this size includes a Blackwall BFGoodrich g-Force Phenom T/A, giving the buyer a distinctly modern tire presentation rather than a traditional collector-style sidewall treatment. This size should be evaluated with close attention to the actual wheel diameter and width already on the car.
A 255/45R19 tire keeps the same 255-millimeter nominal width but uses a 45-series sidewall on a 19-inch rim. For the 2009 Bentley Arnage, this size applies to certain R, RL, and T configurations, so it is important to confirm the exact setup rather than assume every Arnage uses the same wheel package. The metric radial format is familiar to modern buyers and suits a full-size luxury sedan that still needs proper load support and wheel compatibility. This size is best chosen after verifying whether the car remains on its original wheel diameter or has been changed.
A 255/50R18 tire uses the same 255-millimeter nominal width with a taller 50-series sidewall on an 18-inch rim. On the 2009 Bentley Arnage, this size is also used on certain R, RL, and T versions, making it part of a multi-wheel-diameter fitment picture rather than a universal Arnage size. Its metric radial sizing is straightforward, but the practical decision still comes down to the exact wheel package on the car and how much sidewall profile the setup was designed around. It should be considered only after confirming the current 18-inch wheel fitment.
Sub-model fitment matters on the 2009 Bentley Arnage because tire size changes with the exact version and wheel package. The Final Series uses a different size than the R, RL, and T, while those three can use either 18-inch or 19-inch fitments depending on the setup.

2009 Bentley Arnage Final Series
The 2009 Bentley Arnage Final Series uses the 255/40R20 radial size, tying it to a 20-inch wheel fitment. Tire selection here starts with confirming that the car still carries its 20-inch wheels, then comparing available product characteristics within that size.
The 2009 Bentley Arnage R can use either 255/45R19 or 255/50R18 radial tires, so wheel diameter confirmation is essential before choosing a replacement. The real decision is not between two interchangeable sizes, but between two distinct wheel-and-tire setups that need to match the car.
The 2009 Bentley Arnage RL also uses either 255/45R19 or 255/50R18 radial tires, depending on the wheel configuration. That makes the current wheel diameter the first thing to verify before comparing replacement tires or assuming fitment from another Arnage sub-model.
The 2009 Bentley Arnage T shares the same two-size fitment pattern of 255/45R19 or 255/50R18 in radial construction. Selection should begin with the actual wheel size on the car, then move to tire specifications that suit the vehicle’s intended road use and overall setup.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2009 Bentley Arnage Tires for Sale
Current product choice is concentrated in 255/40R20, where the available option uses radial construction with a Blackwall sidewall and an 8.5- to 10-inch rim-width range. That makes wheel-width compatibility an important comparison point alongside size and load specification.
These FAQs focus on exact 2009 Bentley Arnage tire sizing, wheel-diameter differences by sub-model, product-selection factors, and the fitment checks that matter before putting a large luxury Bentley back on the road.
Tire Size & Fitment
What tire size fits a 2009 Bentley Arnage?
The 2009 Bentley Arnage uses three primary tire sizes: 255/40R20, 255/45R19, and 255/50R18. The correct size depends on the exact sub-model and wheel package. Final Series models use 255/40R20, while Arnage R, RL, and T models use either 255/45R19 or 255/50R18.
That means the right starting point is not simply the model name on the trunk, but the actual wheel diameter on the car. Many collector and luxury cars have seen wheel changes over time, so the safest approach is to confirm the current 18-inch, 19-inch, or 20-inch setup before selecting a replacement tire.
What size rim does a 2009 Bentley Arnage use?
A 2009 Bentley Arnage can use 18-inch, 19-inch, or 20-inch rims depending on the sub-model and tire size. The 255/50R18 tire fits an 18-inch rim, the 255/45R19 fits a 19-inch rim, and the 255/40R20 fits a 20-inch rim.
Rim diameter is the most important fitment check on this vehicle because the three tire sizes are tied to three different wheel diameters. Before comparing tread design or brand, inspect the wheel itself and verify its diameter and width so the replacement tire matches the car’s actual wheel setup.
Do all 2009 Bentley Arnage sub-models use the same tire size?
No, 2009 Bentley Arnage sub-models do not all use the same tire size. The Final Series uses 255/40R20, while the Arnage R, RL, and T use either 255/45R19 or 255/50R18. Fitment changes with the specific sub-model and wheel configuration.
This matters because one Arnage owner cannot assume the same tire size applies to another car from the same year. Confirm the exact sub-model, then check the wheel diameter already installed. That two-step check prevents ordering an 18-inch, 19-inch, or 20-inch tire for the wrong wheel package.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 tire for a 2009 Bentley Arnage?
A 255/40R20 tire for the 2009 Bentley Arnage should first match the car’s 20-inch wheel setup, then be evaluated for radial construction, load specification, and rim-width compatibility. In this size, the available product uses a Blackwall sidewall and fits an 8.5- to 10-inch rim-width range.
Selection should reflect how the car will actually be used. A road-driven Arnage needs the correct size and wheel match first, but buyers may also care about modern tire appearance, sidewall presentation, and whether the existing wheel width falls within the tire’s approved range.
What sidewall styles are available for 2009 Bentley Arnage tires?
The currently available 255/40R20 product for the 2009 Bentley Arnage uses a Blackwall sidewall style. That gives the tire a clean modern presentation, which suits the late-production Arnage’s formal but contemporary luxury appearance.
Sidewall style affects appearance more than basic fitment, but it can still matter on a car with this much visual presence. Once the correct size and wheel diameter are confirmed, the sidewall treatment becomes part of the overall look, especially if the car is being kept close to its later-era Bentley character.
What brands offer tires for the 2009 Bentley Arnage?
BFGoodrich currently appears among the available tire choices for the 2009 Bentley Arnage, specifically in the 255/40R20 size. The available product in that fitment is the g-Force Phenom T/A, built as a radial tire for a 20-inch rim.
Brand is only one part of the decision on an Arnage. The more important checks are matching the exact tire size to the wheel diameter on the car, confirming the wheel width falls within the tire’s approved range, and making sure the tire’s specifications suit the vehicle’s weight and intended road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Bentley Arnage?
Yes, modifications can affect tire fitment on a 2009 Bentley Arnage. Changes such as aftermarket wheels, altered wheel widths, suspension height adjustments, or body modifications can all change how a 255/50R18, 255/45R19, or 255/40R20 tire sits in the wheel opening.
That is especially important on a large luxury sedan with multiple factory wheel diameters. A replacement tire should be checked against the actual wheel dimensions on the car, along with steering clearance and fender room, rather than chosen only by model year and sub-model name.
What should I inspect before driving a 2009 Bentley Arnage on new tires?
Before driving a 2009 Bentley Arnage on new tires, inspect wheel diameter and width, confirm the tires were mounted in the correct size, and check inflation pressure. It also helps to look over the suspension, steering, and braking components so the new tires are not being asked to compensate for unrelated wear.
A careful walkaround after installation is worthwhile on any collector or luxury car. Look for rubbing, uneven stance, or signs that the tire sits too close to suspension or body components. A short, cautious road test can then confirm straight tracking, smooth operation, and proper clearance in motion.
How often should tires on a 2009 Bentley Arnage be inspected?
Tires on a 2009 Bentley Arnage should be inspected regularly, especially if the car is driven infrequently. Collector-oriented luxury sedans often spend long periods parked, which makes routine checks for pressure loss, sidewall cracking, cuts, bulges, and uneven tread wear particularly important.
Inspection should happen before longer drives, after storage periods, and anytime ride quality or steering feel changes. Low annual mileage does not prevent tire aging, so appearance and condition matter just as much as tread depth. Keeping the tires clean, properly inflated, and protected from prolonged heat and sunlight also helps.
