The 2018 Bentley Flying Spur blends modern grand touring comfort with the commanding presence expected from a hand-finished luxury sedan. In this model year, Flying Spur buyers were getting a car that could cover long distances in near-silent comfort while still carrying the weight, speed, and road manners of a high-performance Bentley. Tire fitment centers on radial construction, with 275/45R19, 275/40R20, and 275/35R21 sizes depending on the specific configuration and wheel setup. Available choices are concentrated around 275/40R20, where blackwall, redline, and raised white letter options appear across several series and brands. The key is confirming the exact sub-model and wheel diameter before choosing a tire style that matches the car's intended look and use.
Which Tire Size Is Right for The 2018 Bentley Flying Spur
The 2018 Bentley Flying Spur uses three primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. All three are metric radial sizes, but they mount on different 19-inch, 20-inch, or 21-inch rims, so confirming the current wheel setup is the first step before comparing tire style, series, or appearance options.
275/35R21 is a modern metric radial size in which 275 is the section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 21 is the rim diameter in inches. On the 2018 Bentley Flying Spur, this size represents a large-diameter, low-profile fitment suited to configurations using 21-inch wheels. It is part of the Flying Spur's modern radial fitment story rather than a vintage sizing format. This size should be chosen only after confirming that the car is equipped with the correct 21-inch wheel package and that the current wheel and suspension setup remains unchanged.
275/40R20 is a metric radial size that translates to a 275-millimeter section width, a 40-series profile, radial construction, and a 20-inch rim. For the 2018 Bentley Flying Spur, it is the most visibly varied size in the available product mix, with options from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, along with blackwall, redline, and raised white letter sidewall treatments. Tire series also vary, including g-Force, NT555 G2, Street Pro III, and Drag Radial offerings. It is a useful size to evaluate carefully when appearance, intended driving use, and wheel-width compatibility all matter.
275/45R19 is a metric radial size with a 275-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2018 Bentley Flying Spur, this size is associated with 19-inch wheel fitment and carries the tallest profile of the three primary sizes used on this model. Its role is straightforward: it belongs on Flying Spur configurations equipped with the corresponding 19-inch wheels. Before selecting this size, verify that the car has not been changed to a larger wheel package, since rim diameter is the deciding factor here.
Sub-model fitment matters on the 2018 Bentley Flying Spur because not every version uses the same full range of tire sizes. The first step is confirming whether the car is a V8, V8 S, W12, or W12 S, then matching that sub-model to the wheel diameter currently on the vehicle.

2018 Bentley Flying Spur V8
The 2018 Bentley Flying Spur V8 uses radial tire fitments across three possible wheel diameters, making it the broadest sub-model in this group for tire-size coverage. That means selection starts with confirming whether the car is on 19-inch, 20-inch, or 21-inch wheels before comparing available tire styles and series.
The 2018 Bentley Flying Spur V8 S uses radial tire fitments on either 20-inch or 21-inch wheels rather than the full three-size range seen elsewhere. Tire choice therefore depends on confirming the installed wheel diameter first, then deciding whether appearance-focused options such as redline or raised white letter sidewalls are relevant.
The 2018 Bentley Flying Spur W12 uses radial tire sizes tied to 20-inch or 21-inch wheel fitment. The practical takeaway is to verify the exact wheel package on the car before ordering, especially if the vehicle has ever been changed from its original wheel and tire setup.
The 2018 Bentley Flying Spur W12 S also uses radial tire fitments on 20-inch or 21-inch rims. Choosing the right tire begins with wheel confirmation, then moves to comparing the available tire character, sidewall treatment, and intended road use within the correct size.
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.

Tire Size & Fitment
What tire size fits a 2018 Bentley Flying Spur?
The 2018 Bentley Flying Spur uses three primary tire sizes: 275/45R19, 275/40R20, and 275/35R21. All are radial sizes, and the correct one depends on the exact sub-model and, just as importantly, the wheel diameter currently on the car.
A Flying Spur V8 can use all three sizes, while the V8 S, W12, and W12 S use 20-inch or 21-inch fitments. That makes wheel confirmation the first step before choosing a tire, especially on a luxury performance sedan that may have had wheel changes or aftermarket replacements over time.
What size rim does a 2018 Bentley Flying Spur use?
A 2018 Bentley Flying Spur uses 19-inch, 20-inch, or 21-inch rims depending on the tire size fitted to the car. The three matched combinations are 275/45R19 on a 19-inch rim, 275/40R20 on a 20-inch rim, and 275/35R21 on a 21-inch rim.
Rim diameter needs to match the tire size exactly, so this is not a place for approximation. Checking the actual wheel on the car matters because sub-model fitment varies, and some cars may no longer be wearing their original wheel package after replacement or styling upgrades.
Do all 2018 Bentley Flying Spur sub-models use the same tire size?
No. The 2018 Bentley Flying Spur V8 uses 275/45R19, 275/40R20, and 275/35R21, while the V8 S, W12, and W12 S use 275/40R20 and 275/35R21. That means there is overlap across the range, but not every sub-model uses the full set of three sizes.
This matters because tire selection should start with both the sub-model and the wheel diameter on the car. A quick check of the existing tire sidewall or wheel size can prevent ordering the right width in the wrong rim diameter, which is the most important distinction on this page.
Choosing the Right Tire
What should I consider when choosing a 275/40R20 tire for a 2018 Bentley Flying Spur?
Start with the correct size, radial construction, and 20-inch wheel requirement, then compare the intended character of the tire. In 275/40R20, available choices include blackwall street radials, appearance-oriented redline and raised white letter options, and even a drag-focused radial.
The right choice depends on how the Flying Spur is used and how the owner wants it to look. Rim-width guidance, stated load capacity where available, and the tire series itself are all worth comparing, especially on a heavy, high-powered luxury sedan where style and setup both influence the final decision.
What sidewall styles are available for 2018 Bentley Flying Spur tires?
For the 2018 Bentley Flying Spur, the visible sidewall choices in 275/40R20 include blackwall, redline, and RWL, or raised white letter. Those options create very different visual results even when the tire size remains the same.
Blackwall keeps the presentation modern and understated, while redline and raised white letter styles add a more custom or performance-oriented look. Sidewall choice does not change the need to match the correct size and rim diameter, but it can significantly affect how the car presents itself from curbside to show field.
What brands offer tires for the 2018 Bentley Flying Spur?
In 275/40R20, the 2018 Bentley Flying Spur has tire options from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Those brands appear across several radial series, giving the buyer more than one approach within the same basic size.
Brand alone should not make the decision. It is more useful to compare the tire series, sidewall style, stated rim-width compatibility, and any load information that appears with the product, then choose the option that best matches the car's wheels, intended use, and desired appearance.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2018 Bentley Flying Spur?
On a 2018 Bentley Flying Spur, construction itself is straightforward because the primary fitments are radial. The appearance difference comes less from bias-ply versus radial and more from the wheel diameter, tire profile, and sidewall treatment selected within the correct radial size.
A blackwall tire keeps the car close to its modern luxury character, while redline or raised white letter options create a more customized look. Owners pursuing a preservation-minded presentation should compare the car's current wheel-and-tire setup with period photography, marque references, and original delivery documentation before changing its visual stance.
Does correct tire fitment matter for a 2018 Bentley Flying Spur restoration?
Yes, correct tire fitment matters because the 2018 Bentley Flying Spur uses multiple wheel diameters and closely related overall tire dimensions. Staying with the correct size family helps preserve the car's intended proportions and avoids visual mismatches that can make the sedan look under-tired or overly aggressive.
A restoration-oriented approach should begin by confirming the sub-model and wheel package actually on the car. Once that is settled, details such as blackwall, redline, or raised white letter styling can be chosen to support the presentation without drifting away from the proper size and rim-diameter relationship.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Bentley Flying Spur?
Yes. Wheel changes, suspension alterations, ride-height changes, and body modifications can all affect tire fitment on a 2018 Bentley Flying Spur, even when the size sounds close on paper. This matters most on a car using 19-inch, 20-inch, or 21-inch wheel packages with low-profile radial tires.
An owner should verify the actual wheel diameter and width on the car, then check clearance at the fender, inner wheelhouse, and steering range before selecting replacements. Even a correct factory-style tire size can become problematic if the car has aftermarket wheels, spacers, or altered suspension geometry.
What should I inspect before driving a 2018 Bentley Flying Spur on new tires?
Before driving, inspect the wheel condition, confirm the tire size matches the rim diameter, and check that inflation is set correctly for the installed tires. It is also smart to look over valve stems, tread seating, and the sidewalls for any shipping damage or installation-related issues.
A short, careful road test should follow, with attention to vibration, rubbing, pull, or unexpected steering feel. On a heavy luxury performance sedan, even small fitment or balance issues can be noticeable, so a final recheck of pressure and visible clearance after the first miles is worthwhile.
How often should tires on a 2018 Bentley Flying Spur be inspected?
Tires on a 2018 Bentley Flying Spur should be inspected regularly, not just when tread appears worn. A monthly pressure and condition check is a sensible routine, along with a closer inspection before longer drives or anytime the car has been stored for an extended period.
Look for uneven wear, cuts, bulges, cracking, and signs of air loss, especially on low-profile sizes where impacts can be harder on the tire and wheel. Cars that see occasional collector use can age their tires before they wear them out, so condition matters just as much as tread depth.
