The 2011 Bentley Mulsanne marked Bentley’s return to a flagship sedan carrying its own distinct identity, with handcrafted luxury, substantial road presence, and the kind of long-wheelbase composure buyers expect from a top-tier grand touring saloon. Tire selection on this car is tied closely to preserving that balance of ride quality, stance, and wheel fitment. The 2011 Bentley Mulsanne uses radial tires in two primary sizes, 265/40R21 and 265/45R20, depending on the wheel setup. That makes the real decision less about broad fitment and more about confirming wheel diameter first, then choosing the right size for proper appearance, clearance, and road use.
Which Tire Size Is Right for The 2011 Bentley Mulsanne
The 2011 Bentley Mulsanne uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. The first step is confirming whether the car is fitted with 20-inch or 21-inch wheels, since that determines whether 265/45R20 or 265/40R21 is the correct size. Once wheel diameter is confirmed, the focus shifts to maintaining proper overall proportions and ensuring the tire suits the car’s intended road use.
In 265/40R21, the 265 identifies nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 21 is the wheel diameter in inches. On the 2011 Bentley Mulsanne, this size belongs with a 21-inch wheel setup and keeps the car in a modern low-profile luxury-performance format. Its overall dimensions place it very close to the alternate 20-inch fitment in height, but it is not the same tire. This size should be chosen only after verifying that the car is actually equipped with 21-inch wheels and that the wheel package has not been changed.
In 265/45R20, the 265 is the nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 20 is the required rim diameter in inches. For the 2011 Bentley Mulsanne, this size matches a 20-inch wheel configuration while maintaining nearly the same overall tire height as the 21-inch option. That close diameter relationship helps explain why both fitments can exist on the same model, but wheel diameter still decides which one is correct. It is the right choice only when the car is fitted with 20-inch wheels.
The covered 2011 Bentley Mulsanne sub-model is straightforward in one sense and specific in another: the Base model uses both primary tire sizes, but each size belongs to a different wheel diameter. Checking the exact wheel setup matters more than trim name alone when selecting tires for this car.

2011 Bentley Mulsanne Base
The 2011 Bentley Mulsanne Base uses radial tires in both 265/40R21 and 265/45R20, so the key detail is the wheel diameter currently on the car. Tire selection starts with confirming whether the sedan has 21-inch or 20-inch wheels, then matching the size accordingly for proper fitment and proportion.
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
Tire questions for the 2011 Bentley Mulsanne usually come down to confirming whether the car has 20-inch or 21-inch wheels, then understanding how each metric radial size relates to fitment, ride profile, and maintenance on a large luxury sedan.
Tire Size & Fitment
What tire size fits a 2011 Bentley Mulsanne?
The 2011 Bentley Mulsanne uses two primary tire sizes: 265/40R21 and 265/45R20. Both are radial fitments, and each one corresponds to a different wheel diameter rather than a different basic vehicle generation or unrelated application.
The practical step is to confirm which wheels are actually on the car before choosing a tire. A Mulsanne fitted with 21-inch wheels needs 265/40R21, while a 20-inch setup takes 265/45R20. Even though the two sizes are close in overall diameter, they are not interchangeable without the matching rim diameter.
What size rim does a 2011 Bentley Mulsanne use?
A 2011 Bentley Mulsanne uses either a 20-inch or 21-inch rim, depending on the tire size mounted on the car. The 265/45R20 tire belongs on a 20-inch rim, while the 265/40R21 tire belongs on a 21-inch rim.
Rim diameter is the first fitment detail to verify because it determines the correct tire size immediately. Checking the sidewall marking on the current tire and confirming the actual wheel size on the car helps avoid ordering a tire that matches width and profile style but cannot mount to the wheel.
Why does the 2011 Bentley Mulsanne have more than one tire size?
The 2011 Bentley Mulsanne has more than one tire size because it can be fitted with different wheel diameters. The two primary sizes, 265/45R20 and 265/40R21, keep nearly the same overall tire height while pairing with 20-inch and 21-inch wheels respectively.
That means the difference is not simply a matter of preference once the wheels are already chosen. Tire selection should follow the wheel package currently on the vehicle. If the car has had wheel changes at some point, confirm the actual wheel diameter and inspect clearance before assuming either size is still appropriate.
Choosing the Right Tire
What should I consider when choosing a 265/40R21 tire for a 2011 Bentley Mulsanne?
Choosing a 265/40R21 tire for a 2011 Bentley Mulsanne starts with confirming that the car is equipped with 21-inch wheels. This size uses a modern metric radial format and gives the Mulsanne a lower-profile tire presentation than the alternate 20-inch fitment.
After wheel diameter is confirmed, compare the tire’s dimensions against the car’s current setup and intended use. On a large luxury sedan, maintaining the proper balance of clearance, ride character, and overall proportions matters as much as getting the size code right. Any previous wheel or suspension changes should be checked before final selection.
What should I consider when choosing a 265/45R20 tire for a 2011 Bentley Mulsanne?
A 265/45R20 tire is appropriate for a 2011 Bentley Mulsanne only when the car has 20-inch wheels. It is a radial fitment that keeps overall tire height very close to the 21-inch alternative while using a slightly taller sidewall profile on the smaller rim diameter.
That makes wheel confirmation the first requirement, followed by a close look at how the car is actually equipped. Buyers should verify that the wheels are original to the current setup or at least correctly sized, then inspect for any suspension or clearance changes that could affect how the tire sits and operates on the vehicle.
How do I choose between the available tire sizes for a 2011 Bentley Mulsanne?
The choice between tire sizes on a 2011 Bentley Mulsanne is determined by wheel diameter, not by mixing and matching based on appearance alone. A car with 20-inch wheels uses 265/45R20, and a car with 21-inch wheels uses 265/40R21.
Once that is settled, compare each tire against the vehicle’s current condition and intended use. Since both sizes are close in overall diameter, the main concern is not general height but correct wheel compatibility. Cars that have seen aftermarket wheel changes or suspension alterations deserve an extra check before any replacement tire is selected.
Restoration & Appearance
Does correct tire fitment matter for a 2011 Bentley Mulsanne restoration?
Correct tire fitment matters on a 2011 Bentley Mulsanne because the wrong size can change the car’s stance, wheel relationship, and overall presentation. Since this model uses either 265/45R20 or 265/40R21 depending on wheel diameter, maintaining the proper size for the actual wheel package is part of keeping the car visually coherent.
Appearance is only one side of the issue. Correct fitment also helps preserve intended clearance and proportion on a large luxury sedan with substantial bodywork and large wheels. If originality is especially important, verify the car’s exact wheel configuration through vehicle-specific documentation before making appearance-driven tire changes.
How does tire profile affect the appearance of a restored 2011 Bentley Mulsanne?
Tire profile has a noticeable effect on the appearance of a restored 2011 Bentley Mulsanne because the car was designed around large-diameter wheels and a carefully balanced sidewall proportion. The 265/45R20 and 265/40R21 sizes achieve a similar overall height while presenting different sidewall-to-wheel relationships.
That means the visual character changes with the wheel package even when the car remains within proper fitment. The 20-inch setup carries a slightly taller sidewall look, while the 21-inch setup appears lower profile. Any departure from those sizes should be evaluated carefully so the finished stance does not look mismatched to the body and wheel openings.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Bentley Mulsanne?
Modifications can affect tire fitment on a 2011 Bentley Mulsanne, especially when they involve wheels, suspension height, or alignment geometry. Even when the car retains one of its correct primary sizes, changes in wheel width, offset, or ride height can alter how the tire clears the fender, suspension, and steering components.
That makes it important to inspect the car as it sits today rather than assuming any original fitment still applies unchanged. A Mulsanne with aftermarket wheels or suspension changes should have wheel diameter, wheel width, and clearance checked carefully before replacement tires are selected for regular road use.
What should I inspect before driving a 2011 Bentley Mulsanne on new tires?
Before driving a 2011 Bentley Mulsanne on new tires, inspect the wheels for the correct diameter, confirm that the tire size matches the wheel, and check that the tires are seated and inflated properly. It is also wise to look over the valve stems, wheel condition, and general clearance at the fenders and suspension.
A short, careful road test should follow the installation so any vibration, rubbing, or air-loss issue can be caught early. Large luxury sedans place real demands on tires and wheels, so alignment condition and suspension health deserve attention too. Those checks help the car deliver the composed road manners expected from the Mulsanne.
How often should tires on a 2011 Bentley Mulsanne be inspected?
Tires on a 2011 Bentley Mulsanne should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Check for uneven wear, visible cuts, bulges, sidewall cracking, and signs of slow air loss, and make a habit of confirming inflation pressure before longer drives.
Low-use luxury and collector cars can age tires out before wearing them out, so visual condition matters as much as tread depth. A quick inspection every month and a more careful check before extended road use is a sensible routine. Storage away from prolonged heat, sunlight, moisture, and ozone sources also helps protect the tires.
