The 2014 Bentley Mulsanne represents Bentley’s modern flagship sedan in a form that still leans heavily on traditional craftsmanship, long-wheelbase luxury, and effortless grand-touring character. Buyers drawn to a Mulsanne usually care just as much about ride quality and presentation as outright specification. For this model, tire selection centers on two radial fitments, 265/40R21 and 265/45R20, tied directly to the wheel diameter on the car. That makes the key decision less about tire construction and more about confirming whether the car wears 20-inch or 21-inch wheels. Before choosing tires, it is worth checking the current wheel setup carefully, especially on cars that may have seen wheel changes over time.
Which Tire Size Is Right for The 2014 Bentley Mulsanne
The 2014 Bentley Mulsanne uses two primary tire sizes, and both are radial fitments. The most important step is confirming whether the car is equipped with 20-inch or 21-inch wheels, because the two sizes are tied to different rim diameters even though their overall dimensions are very close. Once wheel diameter is confirmed, the decision becomes choosing the right tire within that exact size for the car’s ride, appearance, and intended road use.
A 265/40R21 tire uses a 265-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 21-inch rim diameter. On the 2014 Bentley Mulsanne, this is one of the modern radial fitments and belongs on cars equipped with 21-inch wheels rather than as a substitute for the 20-inch setup. The lower-profile sidewall gives this size a distinctly modern luxury-performance character while still maintaining an overall diameter close to the alternate fitment. It should be chosen only after confirming the actual wheel diameter and making sure the car has not been changed from its current wheel package.
A 265/45R20 tire also carries a 265-millimeter nominal section width and radial construction, but the 45-series profile is paired with a 20-inch rim. For the 2014 Bentley Mulsanne, this size serves the 20-inch wheel setup and keeps overall tire dimensions very close to the 21-inch alternative while using a taller sidewall. That makes wheel confirmation especially important, since similar overall height does not make the two sizes interchangeable across different rim diameters. This size is the right starting point when the car retains its 20-inch wheels and a buyer wants to match that configuration correctly.
The covered 2014 Bentley Mulsanne sub-model fitment is straightforward, but it still requires attention because the same sub-model can use either of two radial tire sizes. Checking the exact wheel diameter on the car matters more than trim naming when selecting between these two options.

Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2014 Bentley Mulsanne, how to verify the correct rim diameter, and what to inspect before choosing replacement tires for a luxury sedan that depends heavily on proper fitment.
Tire Size & Fitment
What tire size fits a 2014 Bentley Mulsanne?
The 2014 Bentley Mulsanne uses two primary tire sizes: 265/40R21 and 265/45R20. Both are radial tires, and the correct one depends on which wheel diameter is actually installed on the car. The 265/40R21 belongs with a 21-inch wheel, while the 265/45R20 belongs with a 20-inch wheel.
Because the two sizes have very similar overall dimensions, the safest way to choose is by confirming the wheel diameter first rather than judging by appearance alone. A Mulsanne that has had wheel changes, replacement wheels, or previous tire service may not still match an expected configuration, so checking the wheel itself before ordering tires is important.
What size rim does a 2014 Bentley Mulsanne use?
A 2014 Bentley Mulsanne can use either a 20-inch rim or a 21-inch rim, depending on the tire size on the car. The 265/45R20 tire is matched to a 20-inch rim, and the 265/40R21 tire is matched to a 21-inch rim. Both fitments are radial and are specific to their respective wheel diameters.
Rim diameter should be confirmed directly on the wheel before selecting replacement tires. Even though the two tire sizes are close in overall height, a 20-inch tire cannot be mounted on a 21-inch wheel, and a 21-inch tire cannot be mounted on a 20-inch wheel. That makes wheel verification the first fitment step on this Mulsanne.
Why does the 2014 Bentley Mulsanne have more than one tire size?
The 2014 Bentley Mulsanne has more than one tire size because it was fitted with different wheel diameters. One setup uses 265/45R20 tires on 20-inch rims, and the other uses 265/40R21 tires on 21-inch rims. Both are legitimate primary fitments for this model year and sub-model coverage.
That means the right tire is determined by the wheel package on the individual car, not by guesswork or by assuming every Mulsanne used the same wheel. Since many luxury cars are later updated with different wheels, it helps to inspect the current setup carefully and match the new tire to the exact rim diameter already in service.
Choosing the Right Tire
What should I consider when choosing a 265/40R21 or 265/45R20 tire for a 2014 Bentley Mulsanne?
Start with the exact size that matches the wheel diameter on the car, because the 2014 Bentley Mulsanne uses either 265/40R21 or 265/45R20 depending on its wheel setup. After that, look at overall tire category, intended road use, and how closely the replacement matches the dimensions and character expected from a large luxury sedan.
A Mulsanne places a premium on smooth road manners, proper load support, and a refined appearance, so it is worth checking the current wheel setup and comparing tire specifications carefully. Cars with aftermarket wheels or altered suspension should be inspected even more closely, since changes in wheel design or ride height can affect clearance and fitment.
How do I choose between the available tire sizes for a 2014 Bentley Mulsanne?
Choosing between the available tire sizes on a 2014 Bentley Mulsanne is not a matter of preference alone. The car uses either 265/45R20 or 265/40R21 based on the wheel diameter installed, so the correct choice begins with identifying whether the car has 20-inch or 21-inch rims. Both sizes are proper radial fitments for this model.
Once wheel diameter is confirmed, compare replacement tires within that exact size instead of crossing between the two. Even though the overall diameters are close, rim diameter remains fixed, and the sidewall profile differs between the 20-inch and 21-inch setups. Matching the tire to the wheel already on the car keeps the selection process accurate and avoids basic mounting problems.
What rim-fitment details should I verify before buying tires for a 2014 Bentley Mulsanne?
The first rim-fitment detail to verify is diameter, since the 2014 Bentley Mulsanne can use either 20-inch or 21-inch wheels. The matching tire sizes are 265/45R20 for the 20-inch setup and 265/40R21 for the 21-inch setup. Confirming that pairing is more important than relying on visual estimates or prior paperwork.
It also helps to inspect the actual wheels on the car for any signs of replacement or modification. A Mulsanne with aftermarket wheels may differ from its original setup in width or design, and that can influence tire selection and clearance. Checking the wheel markings and the currently mounted tire size gives a cleaner starting point before replacement.
Restoration & Appearance
Does correct tire fitment matter for a 2014 Bentley Mulsanne restoration or presentation?
Yes, correct tire fitment matters on a 2014 Bentley Mulsanne because wheel and tire proportions have a strong effect on how the car sits and presents. This model uses either 265/45R20 or 265/40R21, so maintaining the proper relationship between wheel diameter and tire profile helps preserve the balanced look expected of a flagship Bentley sedan.
Presentation is not only visual. A mismatched tire size can also change how the car feels on the road and how naturally it fills the wheel opening. For an appearance-focused project, it is worth confirming the existing wheel package and staying with the correct size family for that setup rather than mixing dimensions simply because they appear close at a glance.
How does tire profile affect the appearance of a 2014 Bentley Mulsanne?
Tire profile plays an important role in the appearance of a 2014 Bentley Mulsanne because the car can wear either a 45-series tire on a 20-inch wheel or a 40-series tire on a 21-inch wheel. Both keep a similar overall diameter, but the sidewall proportion changes the visual balance between tire and wheel.
That difference is especially noticeable on a large luxury sedan, where wheel opening fill and sidewall depth contribute to the car’s stance. A buyer concerned with presentation should avoid treating the two sizes as interchangeable choices and instead match the replacement tire to the actual wheel diameter already on the car for the intended overall look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Bentley Mulsanne?
Yes, modifications can affect tire fitment on a 2014 Bentley Mulsanne. If the car has aftermarket wheels, altered suspension height, or body changes, those changes can influence clearance even when the tire size appears close to the original setup. This matters on a car that already uses two different wheel diameters across its primary fitments.
A modified Mulsanne should be checked for wheel diameter, wheel width, and clearance at full steering and suspension movement before replacement tires are chosen. Even without major changes, previous owners may have installed different wheel packages. Inspecting the current setup directly is the best way to avoid ordering a tire that does not match the car’s actual configuration.
What should I inspect before driving a 2014 Bentley Mulsanne on new tires?
Before driving a 2014 Bentley Mulsanne on new tires, inspect the installed tire size, confirm the wheel diameter, and make sure all four tires match the intended setup. It is also wise to look over the wheels for damage and verify that the tires were mounted and seated correctly. Proper inflation should be checked before the car goes back on the road.
A large luxury sedan puts a premium on smooth, stable road manners, so early inspection matters. Watch for vibration, unusual clearance issues, or any sign of rubbing after installation. It also helps to recheck air pressure after the first period of driving and keep an eye on ride quality, especially if the car has not been used regularly.
How often should tires on a 2014 Bentley Mulsanne be inspected?
Tires on a 2014 Bentley Mulsanne should be inspected regularly, especially if the car is driven infrequently or stored for long periods. A visual check before use can help catch cracking, cuts, bulges, uneven wear, or air loss before they become larger problems. Low-mileage collector-oriented use does not remove the need for routine tire inspection.
Luxury cars often spend time parked, and that makes condition checks just as important as tread depth. Looking at sidewalls, measuring pressure, and watching for changes in ride quality can help catch age-related issues early. Any tire that shows damage, persistent pressure loss, or visible deterioration should be evaluated carefully before longer road use.
