The 1988 Bentley Turbo R marked a more driver-focused chapter for Bentley, blending traditional hand-built luxury with a firmer, more assertive road character than earlier Rolls-Royce-based sedans. It is a substantial performance touring car, so tire choice affects both stance and composure in a very noticeable way. The 1988 Bentley Turbo R uses a 255/65R15 radial tire, giving this car a distinctly modern metric fitment rather than an older bias-ply sizing convention. That keeps the decision centered on selecting the right radial tire dimensions and preserving the car’s intended look on its 15-inch wheels. For restoration-minded owners and regular drivers alike, wheel condition, actual wheel size, and overall tire proportions still deserve a careful check before replacement.
Which Tire Size Is Right for The 1988 Bentley Turbo R
The 1988 Bentley Turbo R uses one primary tire size: 255/65R15. That is a radial tire for a 15-inch wheel, and the same fitment applies to the covered Base sub-model. Since the size itself is straightforward, the real decision is choosing a tire that preserves the correct overall character of the car while confirming wheel condition, dimensions, and clearance on any vehicle that may have seen wheel or suspension changes over time.
255/65R15 is a metric radial size in which 255 indicates the nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. On the 1988 Bentley Turbo R, this is the primary fitment and suits the car’s late-classic luxury-performance character better than an older vintage sizing format. Its dimensions reflect a substantial, wide touring tire profile. This size is the right starting point when the goal is to keep the car’s proportions consistent, provided the actual 15-inch wheel setup on the car is still in place.
Sub-model fitment is straightforward for the 1988 Bentley Turbo R. The covered Base model uses the same primary tire size, so the main task is confirming that the car still has its correct 15-inch wheel configuration before selecting a replacement tire.

Frequently Asked Questions
Common questions for the 1988 Bentley Turbo R usually center on its 255/65R15 tire size, 15-inch wheel fitment, metric radial sizing, restoration-minded tire selection, and the checks worth making before putting a heavy collector luxury car back on the road.
Tire Size & Fitment
What tire size fits a 1988 Bentley Turbo R?
The 1988 Bentley Turbo R uses a 255/65R15 radial tire. That is the primary tire size for this model and it matches a 15-inch wheel diameter, giving the car a modern metric radial fitment rather than an older alphanumeric or numeric vintage size.
Using the correct size matters because this Bentley is a large, heavy performance-luxury sedan with proportions that can be affected noticeably by the wrong tire dimensions. A replacement should be checked against the actual wheel size on the car, especially if it has had aftermarket wheels, suspension work, or long-term storage that may have altered the setup.
What size rim does a 1988 Bentley Turbo R use?
The primary tire fitment for a 1988 Bentley Turbo R is built for a 15-inch rim. That wheel diameter is reflected directly in the 255/65R15 size, where the final number identifies the tire’s intended rim diameter in inches.
Rim diameter is only one part of fitment, so it is worth confirming the actual wheels on the car before buying tires. A Turbo R that has been modified or refitted over time may no longer have its original wheel setup, and wheel width, condition, and clearance should still be reviewed alongside the 15-inch diameter.
Does the 1988 Bentley Turbo R Base use the same tire size?
Yes. The 1988 Bentley Turbo R Base uses the same 255/65R15 radial tire size as the model’s primary fitment. There is no separate tire size change within the covered Base sub-model, so the size question is relatively simple on this vehicle.
That consistency shifts the focus from identifying trim-specific sizing to verifying the car itself. On a collector Bentley, it is smart to inspect the actual wheels, check for prior modifications, and look at the condition of existing tires before replacement, since age, wear, and non-original wheel changes can complicate an otherwise straightforward fitment.
Choosing the Right Tire
What should I consider when choosing a 255/65R15 tire for a 1988 Bentley Turbo R?
Start with the correct 255/65R15 size and radial construction, since that is the primary fitment for the 1988 Bentley Turbo R. From there, the main considerations are maintaining the proper overall proportions of the car, confirming compatibility with the 15-inch wheels, and choosing a tire suited to the vehicle’s combination of luxury weight and road use.
A careful buyer should also look at the actual condition of the wheels and the car’s present setup. A Bentley that has sat for long periods or received suspension or wheel changes may need added fitment checks, and replacement tires should be evaluated for clearance, load suitability, and how well they preserve the car’s intended visual presence.
How do I choose between the available 255/65R15 tires for a 1988 Bentley Turbo R?
The best approach is to treat size accuracy as the first filter and compare the remaining tires by how well they suit the car’s purpose. On a 1988 Bentley Turbo R, that usually means balancing a correct 255/65R15 radial fitment with the owner’s priorities for regular road use, touring comfort, and the visual character expected of a late-classic Bentley.
Beyond size, compare details that affect installation and long-term use, such as wheel compatibility, overall tire presentation, and the condition of the car’s suspension and steering components. Even the right size can behave differently on a vehicle with worn bushings, alignment issues, or non-original wheels, so the tire decision should reflect the complete setup.
What rim-fitment details should I compare when choosing 1988 Bentley Turbo R tires?
The key rim-fitment point is that the 1988 Bentley Turbo R uses a 15-inch wheel with its 255/65R15 tire size. Any replacement tire should be matched to that wheel diameter first, since the final number in the tire size is not flexible if the car still uses its primary wheel setup.
After diameter, attention should turn to the actual wheels on the car. Wheel width, condition, offset, and any previous wheel changes can influence how a tire sits and whether it clears suspension and bodywork properly, so those checks matter just as much as reading the tire size itself on a luxury performance sedan of this size.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Bentley Turbo R?
A period-style starting point for a 1988 Bentley Turbo R is the correct 255/65R15 radial size. Because this Bentley came from an era that already used modern metric radial sizing, keeping the proper dimensions does more for a restoration-minded appearance than forcing the car into an earlier vintage tire format that does not belong to its original design period.
Owners pursuing a more exact restoration should also consider the presentation of the wheel and tire combination as a whole. Tire shape, sidewall look, ride height, and the presence of any non-original wheels can all influence whether the car reads as authentically late-1980s, so marque-specific historical references are helpful when visual accuracy is a priority.
Does correct tire fitment matter for a 1988 Bentley Turbo R restoration?
Yes, correct tire fitment matters because the 1988 Bentley Turbo R has a very specific visual balance. The proper 255/65R15 radial size supports the car’s intended proportions, and an incorrect diameter or profile can make a restored example sit awkwardly or lose some of the substantial touring presence that defines the model.
Fitment also affects more than appearance. A restoration-quality car should have wheels and tires that work together without rubbing, overhang, or obvious mismatch, and old collector cars sometimes carry replacement wheels from earlier ownership. Confirming the actual 15-inch setup before mounting new tires helps protect both the car’s look and its road manners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Bentley Turbo R?
Yes. Even though the primary tire size is 255/65R15, modifications can change how that size works on a 1988 Bentley Turbo R. Aftermarket wheels, altered ride height, suspension repairs, or body changes can all influence tire clearance and the way the tire sits relative to the fenders and steering components.
That makes it important to inspect the actual car rather than relying only on the original size. A 15-inch diameter may still be present, but wheel width, offset, and suspension geometry can shift enough to create rubbing or visual mismatch, so those areas deserve a careful check before mounting replacement tires.
What should I inspect before driving a 1988 Bentley Turbo R on new tires?
Before road use, inspect the wheels, confirm the tire size, and make sure the tires seat properly on the rims. It is also wise to look over the suspension and steering for looseness, check alignment-related wear patterns, and verify that there is no interference at full steering lock or over normal suspension movement.
Collector luxury cars often sit for long periods, so the inspection should include more than the new tires themselves. Old valve stems, wheel corrosion, brake drag, uneven ride height, and aged suspension components can all affect how the car drives, and correcting those issues early helps the 255/65R15 fitment behave as intended.
How often should tires on a 1988 Bentley Turbo R be inspected?
Tires on a 1988 Bentley Turbo R should be inspected regularly, especially if the car is driven infrequently. Visual checks for cracking, cuts, bulges, uneven tread wear, and air loss are important on any collector vehicle, and a low-mileage Bentley can still develop tire problems simply from age and storage conditions.
A practical routine is to check the tires before longer drives and at intervals during storage periods. Looking at pressure, sidewall condition, and tread wear helps catch issues before they become road-use problems, and the inspection should include the wheels as well, since corrosion or damage at the rim can affect tire performance and retention.
