The 2018 Bentley Trucks Bentayga brought Bentley craftsmanship into the ultra-luxury SUV world, blending high-speed touring character with the stance and utility buyers expected from a modern premium sport utility. For owners today, tire selection is less about vintage-style construction and more about matching the exact wheel setup already on the vehicle. This Bentayga uses modern radial fitments in 275/50R20, 285/45R21, and 285/40R22, depending on the sub-model and wheel package. The key decision is confirming the correct rim diameter first, then choosing a tire that suits the vehicle’s use, ride priorities, and overall presentation without disturbing proper clearance.
Which Tire Size Is Right for The 2018 Bentley Trucks Bentayga
Three tire sizes apply to the 2018 Bentley Trucks Bentayga, and they differ by sub-model and wheel diameter. The first step is identifying the exact Bentayga configuration and confirming whether the vehicle is on 20-inch, 21-inch, or 22-inch wheels, because each size is a radial fitment matched to a specific rim diameter. Once that is settled, the decision becomes selecting the right tire within the proper size for road use, appearance, and overall wheel compatibility.
Fit(s): Activity Edition, Mulliner, Onyx Edition, W12, and W12 Signature
Construction: Radial|Rim: 20 in
275/50R20 is a metric radial size in which 275 identifies the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2018 Bentley Trucks Bentayga, this is one of the modern radial fitments used on 20-inch wheels. Its dimensions place it in the larger luxury SUV touring range rather than a vintage sizing system. This size should be evaluated when the vehicle is equipped with the correct 20-inch wheel setup and the sub-model supports that fitment.
Fit(s): Activity Edition, Black Edition, Mulliner, Onyx Edition, W12, and W12 Signature
Construction: Radial|Rim: 22 in
285/40R22 is a metric radial size where 285 is the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 22 indicates a 22-inch rim. For the 2018 Bentley Trucks Bentayga, this size is tied to a 22-inch wheel package and is the sole fitment used by the Black Edition. Compared with the other Bentayga sizes, it represents a lower-profile modern SUV tire format. It is the size to focus on when the vehicle carries 22-inch wheels and clearance should remain consistent with that setup.
Fit(s): Activity Edition, Mulliner, Onyx Edition, W12, and W12 Signature
Construction: Radial|Rim: 21 in
285/45R21 is a metric radial tire size with a 285-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 21-inch rim diameter. On the 2018 Bentley Trucks Bentayga, it serves as one of the modern radial fitments for vehicles equipped with 21-inch wheels. Its sizing sits between the 20-inch and 22-inch Bentayga options in rim diameter and profile. This size belongs on Bentayga configurations that use the correct 21-inch wheel package, so wheel identification should come before comparing tire choices.
Sub-model fitment matters on the 2018 Bentley Trucks Bentayga because not every version uses the same wheel and tire setup. Most covered sub-models can appear with all three radial sizes, but the Black Edition is tied specifically to the 22-inch 285/40R22 fitment.

2018 Bentley Trucks Bentayga Activity Edition
The Activity Edition can use 275/50R20, 285/45R21, or 285/40R22 radial tires depending on the wheel package installed on the vehicle. Tire selection starts with confirming the actual wheel diameter, then choosing within that exact size rather than treating all Bentayga fitments as interchangeable.
The Black Edition uses the 285/40R22 radial tire size, making its fitment more straightforward than the other covered Bentayga versions. The main selection point is choosing the right 22-inch tire for the existing wheel setup while keeping overall wheel and clearance requirements in mind.
The Mulliner can be equipped with 275/50R20, 285/45R21, or 285/40R22 radial tires, so the wheel package on the vehicle must be confirmed before replacing tires. Once the rim diameter is verified, the buyer can focus on tire choice within the correct modern metric size.
The Onyx Edition appears with 275/50R20, 285/45R21, or 285/40R22 radial fitments depending on the wheel diameter fitted to the vehicle. That makes wheel confirmation the key first step before comparing replacement tires or considering any change from the existing setup.
The W12 uses one of three modern radial sizes: 275/50R20, 285/45R21, or 285/40R22, depending on the wheel package. Choosing the right tire means matching the exact wheel diameter already on the vehicle and then checking for proper compatibility within that size.
The W12 Signature can use 275/50R20, 285/45R21, or 285/40R22 radial tires, so there is no single universal size across every example. Confirming whether the vehicle is on 20-inch, 21-inch, or 22-inch wheels is the essential first step before selecting replacement tires.
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
Common questions for the 2018 Bentley Trucks Bentayga usually center on identifying the correct tire size by sub-model, confirming wheel diameter, and understanding how modifications or maintenance can affect modern radial fitment on a luxury SUV.
Tire Size & Fitment
What tire size fits a 2018 Bentley Trucks Bentayga?
The 2018 Bentley Trucks Bentayga uses three radial tire sizes: 275/50R20, 285/45R21, and 285/40R22. The correct one depends on the exact sub-model and, just as importantly, the wheel diameter on the vehicle, since these sizes are matched to 20-inch, 21-inch, and 22-inch rims.
The practical first step is checking the wheel setup already installed rather than assuming every Bentayga uses the same tire. Once the rim diameter is confirmed, the buyer can match the proper size to the vehicle and avoid mixing fitments that belong to different wheel packages.
What size rim does a 2018 Bentley Trucks Bentayga use?
A 2018 Bentley Trucks Bentayga can use 20-inch, 21-inch, or 22-inch rims depending on configuration. Those rim diameters correspond to the vehicle’s three tire sizes: 275/50R20, 285/45R21, and 285/40R22, all in radial construction.
Rim diameter should be confirmed before any tire purchase because the Bentayga does not rely on one universal wheel size across all covered versions. Checking the wheel itself, the existing tire sidewall, and the exact sub-model helps prevent choosing a tire that belongs to a different factory wheel package.
Do all 2018 Bentley Trucks Bentayga sub-models use the same tire size?
No, the covered 2018 Bentley Trucks Bentayga sub-models do not all use the same tire size. Activity Edition, Mulliner, Onyx Edition, W12, and W12 Signature can use 275/50R20, 285/45R21, or 285/40R22, while the Black Edition is tied to 285/40R22.
That difference means the sub-model name alone is helpful, but the wheel diameter on the vehicle still needs to be checked before selecting tires. On a Bentayga that has had wheel changes over time, the actual wheel and tire combination matters more than relying on a broad model-level assumption.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Bentley Trucks Bentayga?
Start with the exact tire size and wheel diameter used on the vehicle: 275/50R20, 285/45R21, or 285/40R22. Because the 2018 Bentley Trucks Bentayga uses multiple modern radial fitments, the right choice begins with matching the tire to the installed 20-inch, 21-inch, or 22-inch wheel.
After size is confirmed, compare tires within that exact fitment based on intended road use, ride expectations, and the condition of the vehicle’s wheels and suspension. A Bentayga used for regular touring may call for a different replacement emphasis than one driven only occasionally, but the correct size remains the foundation.
How do I choose between the available 2018 Bentley Trucks Bentayga tire sizes?
The available Bentayga tire sizes are not alternatives to choose from freely; they are tied to different wheel diameters and sub-model setups. A 20-inch wheel uses 275/50R20, a 21-inch wheel uses 285/45R21, and a 22-inch wheel uses 285/40R22.
That means selection starts with the vehicle as it sits today, not with a preference for one size over another. Any change from one factory-style wheel diameter to another should be treated as a full wheel-and-tire fitment decision, with attention to clearance, overall setup, and how the vehicle is used.
Why does the 2018 Bentley Trucks Bentayga have more than one tire size?
The 2018 Bentley Trucks Bentayga has more than one tire size because it was offered with different wheel diameters across the covered sub-models and configurations. That is why 275/50R20, 285/45R21, and 285/40R22 all appear as valid radial fitments within the same model year.
For the buyer, that means a model-year match is only the starting point. The real fitment decision comes from confirming the exact sub-model and checking whether the vehicle is running 20-inch, 21-inch, or 22-inch wheels before comparing replacement tires.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Bentley Trucks Bentayga restoration or refurbishment?
Yes, correct tire fitment still matters on a 2018 Bentley Trucks Bentayga even though it is a modern luxury SUV rather than a vintage restoration project. Using the proper radial size for the installed wheel diameter helps preserve the vehicle’s intended stance, wheel-to-tire proportion, and overall presentation.
On a refurbishment-minded Bentayga, appearance and fitment usually go together. Matching the correct 20-inch, 21-inch, or 22-inch size is a better starting point than chasing a different look through an incorrect tire, especially when the goal is to keep the vehicle visually balanced and properly set up.
How does tire size affect the appearance of a 2018 Bentley Trucks Bentayga?
Tire size has a visible effect on the 2018 Bentley Trucks Bentayga because each fitment is tied to a different wheel diameter and sidewall profile. The 275/50R20, 285/45R21, and 285/40R22 sizes each create a different visual balance between wheel face and sidewall height.
That is why appearance changes should be approached through the correct wheel-and-tire combination rather than by substituting an unrelated size. Even on a newer luxury SUV, keeping the proper fitment helps the vehicle look composed while reducing the risk of clearance or compatibility problems.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Bentley Trucks Bentayga?
Yes, modifications can affect tire fitment on a 2018 Bentley Trucks Bentayga. If the vehicle has aftermarket wheels, suspension changes, altered ride height, or body modifications, those changes can influence which of the original radial sizes still works properly and how much clearance remains.
A modified Bentayga should be checked at full steering lock and through normal suspension travel before settling on replacement tires. Wheel diameter, wheel width, and the actual tire size on the vehicle all matter, especially when the SUV no longer matches its original wheel-and-suspension configuration.
What should I inspect before driving a 2018 Bentley Trucks Bentayga on new tires?
Before driving a 2018 Bentley Trucks Bentayga on new tires, inspect the wheels for damage, confirm the correct tire size for the installed rim diameter, and make sure inflation is set appropriately for the vehicle’s use. It is also wise to check that there is no rubbing at the fenders, suspension, or steering components.
A road-ready inspection should also include tread seating, valve condition, and a close look at alignment or suspension issues that could shorten tire life. On a heavy luxury SUV, those basic checks matter just as much as the tire size itself, especially after any recent wheel or suspension work.
How should tires on a 2018 Bentley Trucks Bentayga be maintained?
Tires on a 2018 Bentley Trucks Bentayga should be maintained with regular pressure checks, visual inspections for cuts or bulges, and periodic review of tread wear across all four corners. Because the Bentayga uses large-diameter modern radial tires, even small problems can become noticeable quickly in ride quality and wear pattern.
Low-use vehicles still need attention, since age, storage conditions, and long periods of sitting can affect tire condition even when tread depth looks acceptable. Keeping the SUV clean, moving it periodically, and inspecting for cracking or air loss helps maintain road readiness between longer drives.
