The 2006 Bentley Arnage sits in the final chapter of Bentley’s hand-built, large-displacement luxury sedans, blending old-world presence with modern grand-touring capability. Buyers drawn to an Arnage today are usually balancing preservation, road manners, and the visual authority that a proper wheel-and-tire package gives the car. Tire selection matters here because the 2006 Bentley Arnage uses two radial sizes, 255/45R19 and 255/50R18, depending on the specific sub-model and wheel setup. That makes the choice less about vintage construction and more about confirming the correct rim diameter first. Once that is settled, the focus shifts to matching the right size to the car’s intended use and current wheel configuration.
Which Tire Size Is Right for The 2006 Bentley Arnage
The 2006 Bentley Arnage uses two primary tire sizes, and the difference comes down to wheel diameter rather than a change from one construction type to another. Both sizes are radial, but some Arnage sub-models can use either 18-inch or 19-inch fitments, so the first step is confirming the exact sub-model and the actual wheels on the car before choosing tires.
255/45R19 is a metric radial size in which 255 identifies the nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 19 is the wheel diameter in inches. On the 2006 Bentley Arnage, this size serves the 19-inch wheel fitment and reflects the more modern sizing language expected on a late-production luxury performance sedan. Because it appears across multiple Arnage sub-models, this size is often a key reference point when confirming replacement tires. It is the right size to evaluate only after verifying that the car is actually fitted with 19-inch wheels.
255/50R18 is also a metric radial size, with the same 255-millimeter nominal width but a 50-series profile on an 18-inch wheel. For the 2006 Bentley Arnage, this size supports the 18-inch fitment used on certain covered configurations, giving buyers a second primary size to consider within the same model year. Its dimensions place it in the same general fitment conversation as the 19-inch option, but the wheel diameter remains different and must match the car. This is the size to pursue when the Arnage retains or has been fitted with 18-inch wheels.
Sub-model fitment on the 2006 Bentley Arnage is mostly straightforward, but it is not identical across the range. Checking the exact Arnage variant matters because the Blue Train uses one size, while the R, RL, and T can be associated with both 18-inch and 19-inch radial fitments.

2006 Bentley Arnage R
The 2006 Bentley Arnage R can use either the 255/45R19 or 255/50R18 radial size, so wheel diameter is the key detail before selecting tires. That means the tire decision starts with confirming whether the car is on 19-inch or 18-inch wheels rather than choosing between different construction types.
The 2006 Bentley Arnage R Blue Train uses the 255/45R19 radial size, making its fitment path more specific than the broader Arnage R. Tire selection here centers on staying with the correct 19-inch metric radial size and confirming that the car still carries its intended wheel setup.
The 2006 Bentley Arnage RL is associated with both 255/45R19 and 255/50R18 radial fitments. For an RL owner, the practical step is verifying the wheel diameter on the car now, especially if the vehicle has seen wheel changes during its life.
The 2006 Bentley Arnage T can also use either 255/45R19 or 255/50R18 in radial construction. That makes exact wheel confirmation essential before replacement, since both sizes belong to this sub-model but are tied to different rim diameters.
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.
Frequently Asked Questions
Owners of a 2006 Bentley Arnage usually need to sort out the correct tire size by sub-model and wheel diameter first. The questions below focus on fitment, radial sizing, product-selection factors, appearance considerations, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2006 Bentley Arnage?
The 2006 Bentley Arnage uses two primary tire sizes: 255/45R19 and 255/50R18. Both are radial sizes, and the correct one depends on the specific Arnage sub-model and the wheel diameter fitted to the car.
The practical step is to confirm whether the car has 18-inch or 19-inch wheels before choosing a tire. Several Arnage variants can be associated with either size, so relying on the model name alone is not always enough if the wheels have ever been changed.
What size rim does a 2006 Bentley Arnage use?
A 2006 Bentley Arnage uses either an 18-inch or 19-inch rim, depending on the tire size fitted to the car. The 255/50R18 size mounts on an 18-inch rim, while the 255/45R19 size mounts on a 19-inch rim.
Rim diameter should be confirmed before any replacement purchase because the two sizes are not interchangeable across the same wheel. Checking the wheel itself is especially important on a collector luxury sedan, where prior owners may have changed wheels while keeping a similar overall tire profile.
Do all 2006 Bentley Arnage sub-models use the same tire size?
No. The 2006 Bentley Arnage R, RL, and T can use either 255/45R19 or 255/50R18, while the 2006 Bentley Arnage R Blue Train uses 255/45R19. That means fitment varies within the Arnage lineup for this model year.
Sub-model identification helps narrow the choices, but wheel confirmation still matters because some variants are associated with both sizes. A quick check of the current wheel diameter and the size already on the car is the safest way to avoid selecting the wrong fitment.
Choosing the Right Tire
What should I consider when choosing a 255/45R19 or 255/50R18 tire for a 2006 Bentley Arnage?
Start with the exact size the car uses now, since the 2006 Bentley Arnage can take either 255/45R19 or 255/50R18 depending on sub-model and wheel diameter. Both are radial sizes, so the main fitment question is matching the tire to the correct rim.
After confirming size, compare the tire’s intended use with how the Arnage is driven and maintained. A low-mileage collector car, a regularly exercised touring sedan, and a modified example may each call for a slightly different approach to wheel verification, clearance checks, and overall tire condition.
How do I choose between the available 2006 Bentley Arnage tire sizes?
Choosing between the available Arnage sizes is not a matter of preference alone, because 255/45R19 and 255/50R18 belong to different wheel diameters. The right choice is the size that matches the actual wheels on the specific 2006 Bentley Arnage being serviced.
A car that has remained in original-style configuration may be straightforward, but any prior wheel change can alter the answer quickly. Looking at the sidewall on the current tire and measuring wheel diameter will usually resolve the question faster than relying only on model or trim assumptions.
What tire series are available for the 2006 Bentley Arnage?
Tire selection for the 2006 Bentley Arnage centers on the correct radial size rather than on named vintage tire series. The key fitments here are 255/45R19 and 255/50R18, and the more important distinction is which wheel diameter the car uses.
That shifts the buying decision toward exact sizing, wheel compatibility, and the present condition of the car’s wheel-and-suspension setup. On a large luxury sedan like the Arnage, getting the fitment baseline right matters more than chasing a series name that does not define the vehicle’s primary tire requirement.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Bentley Arnage?
A period-style choice for a 2006 Bentley Arnage starts with using the correct primary size for the car: either 255/45R19 or 255/50R18. Since the Arnage is a modern-era luxury sedan with radial fitments, maintaining the proper size and wheel diameter does more for its appearance than forcing an unrelated alternative.
A well-kept Arnage looks right when the tire proportions suit the body and wheel package the car actually carries. Owners pursuing a highly exact presentation should also compare the current setup with marque references, photos, and vehicle-specific historical material before making appearance-driven changes.
Does correct tire fitment matter for a 2006 Bentley Arnage restoration?
Yes, correct tire fitment matters because the 2006 Bentley Arnage uses specific radial sizes tied to either 18-inch or 19-inch wheels. Even on a modern collector sedan, the wrong rim diameter or incorrect size can change the car’s stance, visual balance, and overall presentation.
A restoration-minded owner should confirm the exact sub-model and inspect the wheels currently on the car before replacing tires. That is especially worthwhile on luxury cars that may have passed through several owners, where wheel changes can blur what belongs on the vehicle today.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Bentley Arnage?
Yes. Wheel changes, suspension alterations, or body modifications can affect tire fitment on a 2006 Bentley Arnage even when the tire size appears close to the original specification. This matters because the car already has two legitimate fitment paths, one on 18-inch wheels and one on 19-inch wheels.
A modified Arnage should be checked for actual wheel diameter, wheel width, and clearance at the fenders and suspension before replacement tires are chosen. Looking at the current setup on the car is more reliable than assuming the original trim designation still tells the full fitment story.
What should I inspect before driving a 2006 Bentley Arnage on new tires?
Before driving a 2006 Bentley Arnage on new tires, inspect the wheels for damage, confirm the tires match the car’s 18-inch or 19-inch fitment, and make sure inflation is set appropriately for the installed tires. It is also worth checking that each tire seats properly and clears the surrounding body and suspension.
A careful road-use check should include looking for uneven wear, vibration, air loss, or rubbing once the car is moving again. On a heavy luxury sedan that may spend time parked between drives, early inspection after installation helps catch setup issues before they become expensive problems.
How often should tires on a 2006 Bentley Arnage be inspected?
Tires on a 2006 Bentley Arnage should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Age, pressure loss, sidewall cracking, tread wear, cuts, and bulges all deserve attention even when the vehicle covers very few miles.
A practical routine is to look over the tires before each longer drive and to give them a fuller inspection during routine service intervals. Collector-oriented cars often age their tires through time and storage conditions rather than mileage alone, so visual condition matters as much as tread depth.
