The 1993 Bentley Turbo R sits in the era when Bentley's large luxury sedans began projecting a more assertive driver-focused identity without losing their traditional long-wheelbase presence and handcrafted character. It is a serious grand touring car, and its tire choice plays a visible role in preserving both stance and road manners. For this model, the primary fitment is a 255/65R15 radial, giving the Turbo R a distinctly modern metric tire format rather than an older bias-ply specification. Because both Base and LWB versions share that same size, the main decision centers on selecting the right radial tire and confirming wheel condition, dimensions, and overall vehicle setup before road use.
Which Tire Size Is Right for The 1993 Bentley Turbo R
The 1993 Bentley Turbo R uses one primary tire size: 255/65R15, a radial tire for a 15-inch rim. That fitment stays consistent across the covered Base and LWB versions, so the question is less about sorting through multiple factory sizes and more about understanding what 255/65R15 means, choosing the right radial tire within that size, and confirming that the wheels on the car still match the intended setup.
A 255/65R15 tire uses a metric sizing system: 255 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1993 Bentley Turbo R, that radial format suits a later luxury-performance sedan that was built around modern road manners rather than vintage bias-ply behavior. The size also reflects a substantial footprint appropriate to the car's weight, presence, and touring character. Selecting this size correctly means confirming the wheel remains a 15-inch fitment and that any replacement preserves the clearance and overall presentation expected for the Turbo R.
Tire fitment is straightforward on the 1993 Bentley Turbo R because both covered sub-models use the same 255/65R15 radial size. Checking the exact sub-model still helps confirm that the car has not been altered with different wheels or a nonstandard suspension setup over time.

1993 Bentley Turbo R Base
The 1993 Bentley Turbo R Base uses the same 255/65R15 radial fitment as the rest of the covered lineup. That keeps tire selection focused on choosing the right modern radial in the proper size and verifying that the car still retains the intended 15-inch wheel setup.
The 1993 Bentley Turbo R LWB also uses 255/65R15 radial tires, so the long-wheelbase version does not introduce a separate primary size. Tire selection remains centered on the correct metric radial fitment, with added attention to wheel condition, clearance, and the actual configuration of the car today.
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
These FAQs focus on 1993 Bentley Turbo R tire size, 15-inch rim fitment, radial construction, choosing the proper 255/65R15 tire, and the condition checks worth making before putting a heavy luxury-performance sedan back on the road.
Tire Size & Fitment
What tire size fits a 1993 Bentley Turbo R?
The 1993 Bentley Turbo R uses a 255/65R15 tire size. That is the primary fitment for both the Base and LWB versions, and it is a radial tire rather than a vintage bias-ply format.
That consistency makes selection simpler, but it is still worth confirming the car has its intended 15-inch wheels before replacing tires. Many older luxury cars have seen wheel changes over time, so checking the actual wheel diameter, overall clearance, and the condition of the existing setup is just as important as matching the size code itself.
What size rim does a 1993 Bentley Turbo R use?
The 1993 Bentley Turbo R uses a 15-inch rim with its 255/65R15 tire fitment. The 15 in the tire size is the wheel diameter in inches, which is the key dimension that must match the tire.
Rim diameter is the first thing to confirm before ordering replacement tires, especially on a collector-era Bentley that may have changed hands several times. A tire can share a similar overall look yet still be wrong for the wheel, so verifying the wheel markings and measuring the actual setup helps avoid fitment, clearance, and mounting issues.
Do all 1993 Bentley Turbo R sub-models use the same tire size?
Yes. Both the 1993 Bentley Turbo R Base and the 1993 Bentley Turbo R LWB use the same 255/65R15 radial tire size. There is no separate primary size for the long-wheelbase version in this covered fitment.
That shared fitment means the real next step is evaluating the condition and originality of the wheel-and-tire package already on the car. A previous owner may have fitted different wheels or altered ride height, so even when the official size is straightforward, the actual vehicle should still be checked before final tire selection.
Choosing the Right Tire
What should I consider when choosing a 255/65R15 tire for a 1993 Bentley Turbo R?
Start with the correct size and construction: the 1993 Bentley Turbo R uses a 255/65R15 radial on a 15-inch rim. That makes size accuracy the first priority, followed by choosing a tire that suits the car's luxury-touring character and substantial curb weight.
After confirming size, inspect the wheels themselves and compare the tire's intended use with how the car is driven today. A Turbo R used for regular road miles may call for different priorities than one kept mainly for occasional collector use, and wheel condition, suspension health, and clearance all deserve a close look before mounting new tires.
How do I choose between the available 255/65R15 tires for a 1993 Bentley Turbo R?
The best approach is to compare tires within the correct 255/65R15 size rather than treating every tire in that size as identical. Construction is already established as radial, so the meaningful differences usually come down to how closely a tire matches the car's intended road use, presentation, and wheel setup.
A Bentley of this era rewards careful selection because tire choice affects both appearance and driving feel. Look at the actual condition of the suspension, confirm that the wheels remain true and undamaged, and choose a tire that supports the way the car will be used instead of selecting only by size code.
What rim-fitment details should I compare when choosing 1993 Bentley Turbo R tires?
The most important rim-fitment detail is wheel diameter, since the 1993 Bentley Turbo R uses a 15-inch wheel with its 255/65R15 tire. The tire and wheel must match at that diameter before any other fitment question can be resolved.
Wheel condition and actual vehicle setup matter too, especially on a heavy luxury sedan that may have older rims, prior repairs, or aftermarket changes. It is smart to inspect for bent wheels, bead-seat corrosion, and any mismatch between the wheel on the car and the intended tire size before putting the Bentley back into regular service.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Bentley Turbo R?
A period-style starting point for a 1993 Bentley Turbo R is the correct 255/65R15 radial size on the proper 15-inch rim. Because this car belongs to a later collector era, keeping the right metric radial profile does more for an authentic overall presentation than forcing an earlier-looking vintage construction.
Appearance still needs to work with the car's actual stance and wheel setup, so focus first on preserving the intended proportions. For buyers pursuing a highly exact restoration, factory literature, marque-club references, and the car's own historical records are useful guides when deciding how closely the replacement tire should mirror the original visual impression.
Does correct tire fitment matter for a 1993 Bentley Turbo R restoration?
Yes, correct tire fitment matters because the 1993 Bentley Turbo R has a distinctive combination of formal body lines, substantial wheel openings, and a road-focused stance. Using the proper 255/65R15 radial size helps preserve those proportions and keeps the car from looking under-tired, over-tired, or visually out of period.
Restoration-minded owners should think beyond simple diameter and pay attention to how the tire fills the wheel opening and complements the car's character. Even if the vehicle is not being restored to concours standards, staying with the intended size is usually the best foundation before evaluating cosmetic details or any nonstandard wheel choices.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Bentley Turbo R?
Yes. Even though the 1993 Bentley Turbo R uses a straightforward 255/65R15 radial fitment, aftermarket wheels, suspension changes, or altered ride height can affect whether that size works the same way on an individual car. Fitment on paper and fitment on the vehicle are not always identical after modifications.
A changed wheel diameter or width is the first thing to check, followed by steering and fender clearance through the full range of movement. A Bentley that has been lowered, repaired, or reworked over the years may need closer inspection before new tires are mounted, even when the replacement size itself is correct.
What should I inspect before driving a 1993 Bentley Turbo R on new tires?
Before driving on new tires, inspect the wheels for damage or corrosion, verify that the 15-inch rims match the intended 255/65R15 fitment, and make sure the suspension and steering components are in sound condition. On a heavy grand touring sedan, small issues can become more noticeable once fresh tires are installed.
It also helps to check alignment, air retention, and basic clearance at the fenders and suspension. A careful road-use inspection should include looking for fluid leaks, worn bushings, uneven old tire wear, and anything else that suggests the chassis may not be supporting the new tires evenly across normal driving conditions.
How should 255/65R15 tires on a collector 1993 Bentley Turbo R be maintained?
255/65R15 tires on a collector 1993 Bentley Turbo R should be inspected regularly for cracking, cuts, bulges, tread wear, and gradual air loss, especially if the car is driven infrequently. Collector cars often accumulate age faster than mileage, so condition matters at least as much as tread depth.
Storage practices also make a difference. Keeping the Bentley away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives, while periodic pressure checks and short inspections before each outing help catch problems early on a vehicle that may spend long periods parked.
