The 1989 Bentley Mulsanne represents the formal, long-wheelbase British luxury sedan tradition that carried Bentley through the late twentieth century with understated presence and serious road manners. Buyers looking after one today are usually balancing elegant appearance, correct proportions, and dependable touring use rather than chasing a dramatic fitment change. This car uses a 235/70R15 radial tire on a 15-inch rim, so the focus is less about sorting through multiple factory sizes and more about choosing the right version of that size. Available options include blackwall, narrow whitewall, wide whitewall, redline, and raised white letter designs across several premium-style series. The right choice depends on whether the goal is a restrained luxury presentation, a restoration-oriented look, or regular road use with careful wheel and clearance verification.
Which Tire Size Is Right for The 1989 Bentley Mulsanne
The 1989 Bentley Mulsanne uses one primary tire size: 235/70R15, a radial fitment for a 15-inch rim. The Mulsanne S uses the same size, so the main decision is not which size fits, but which tire style, sidewall treatment, and series best match the car’s appearance goals and intended road use.
235/70R15 is a metric radial size in which 235 identifies the section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 15 is the rim diameter in inches. On the 1989 Bentley Mulsanne, this size supports the car’s late-classic luxury-touring character with a modern radial layout rather than an earlier bias-ply format. Within this size, choices include blackwall, narrow whitewall, wide whitewall, redline, and raised white letter designs from Avon, BFGoodrich, Cooper, and Michelin across series such as Silvertown Radial, Michelin XVS, Turbosteel, Cobra Radial G/T, and Radial T/A. That gives owners room to select a tire that suits the car’s visual tone while still staying with the proper primary fitment size.
Sub-model fitment is straightforward here because the covered 1989 Bentley Mulsanne configuration uses the same primary tire size throughout. Checking the exact sub-model still matters so the tire selection matches the vehicle’s intended appearance and preserves the correct 15-inch fitment.

1989 Bentley Mulsanne S
The 1989 Bentley Mulsanne S uses the same 235/70R15 radial tire size as the model core. That keeps tire selection centered on sidewall style, tire series, and wheel-width compatibility rather than sorting through different primary sizes.
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 1989 Bentley Mulsanne?
The 1989 Bentley Mulsanne uses a 235/70R15 radial tire. That size is the primary fitment for this application and keeps the car on a 15-inch rim with the proportions expected for a late-classic Bentley luxury sedan.
The practical decision is choosing the right version of 235/70R15 rather than searching for another primary size. Sidewall treatment, tire series, brand, and wheel-width compatibility all matter, especially if the car has replacement wheels or has been restored with appearance goals in mind.
What size rim does a 1989 Bentley Mulsanne use?
The 1989 Bentley Mulsanne uses a 15-inch rim with its 235/70R15 tire size. That 15-inch diameter is built into the tire size itself, and the available tires in this fitment are designed around that wheel diameter.
Rim diameter is only part of the check. Wheel width also matters, since available 235/70R15 products in this application carry different approved rim-width ranges. Before choosing a tire, confirm the actual wheel size on the car, especially if the wheels may have been changed at some point.
Does the 1989 Bentley Mulsanne S use the same tire size?
Yes. The 1989 Bentley Mulsanne S uses the same 235/70R15 radial tire size. That keeps fitment simple across the covered Mulsanne application and means the sub-model does not introduce a different primary diameter or alternate construction.
Even with the same tire size, owners still have meaningful choices within the category. Whitewall, blackwall, redline, and raised white letter options are available, so the next step is matching the tire’s look and wheel-width requirements to the way the car is being maintained, restored, or driven.
Choosing the Right Tire
What should I consider when choosing a 235/70R15 tire for a 1989 Bentley Mulsanne?
Start with the correct size, 235/70R15, and confirm that the tire matches the car’s 15-inch wheel setup. From there, compare radial tire series, sidewall style, approved rim-width range, and any load figures that are important for how the car will be used.
A Bentley Mulsanne often needs a tire that looks appropriate on the car as much as one that simply shares the size code. A restrained blackwall or narrow whitewall can suit a formal luxury presentation, while wheel dimensions and clearance should still be checked before finalizing any choice.
What sidewall styles are available for 1989 Bentley Mulsanne tires?
The 1989 Bentley Mulsanne’s 235/70R15 tire size is available with several sidewall treatments, including blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles. Those options can change the visual character of the car even when the underlying size remains the same.
Choosing among them depends on how the car is presented. Blackwall and narrow whitewall options usually keep a more formal look, while wide whitewall, redline, or raised white letter styles create a more distinct visual statement. The tire should still be matched to the actual wheel dimensions on the vehicle.
What brands offer tires for the 1989 Bentley Mulsanne?
Tires for the 1989 Bentley Mulsanne’s 235/70R15 fitment are available from Avon, BFGoodrich, Cooper, and Michelin. The available series include Turbosteel 70 CR11B, Silvertown Radial, Cobra Radial G/T, Radial T/A, and Michelin XVS.
Brand choice should be used as part of a broader comparison rather than the only decision point. It helps to compare sidewall style, rim-width range, weight, and the overall presentation each series brings, especially on a car where appearance and road manners both matter.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Bentley Mulsanne?
A period-style 1989 Bentley Mulsanne usually starts with the correct 235/70R15 radial size and then narrows the choice by sidewall treatment and series character. Blackwall, narrow whitewall, and wide whitewall options all exist, so the visual direction can be tailored without changing the primary fitment.
The best appearance choice depends on how the car is being presented, from formal luxury touring to a more restoration-oriented look. When exact originality matters, it is worth checking marque-specific references and the car’s own history before selecting a sidewall style simply because it is available in the correct size.
Does correct tire fitment matter for a 1989 Bentley Mulsanne restoration?
Yes. Correct tire fitment matters on a 1989 Bentley Mulsanne restoration because the tire’s size and sidewall profile have a strong effect on stance, wheel opening fill, and the car’s overall visual balance. Staying with 235/70R15 preserves the intended 15-inch fitment relationship.
Appearance is only part of the equation. The wheel’s actual width, the tire’s approved rim range, and the condition of the suspension and steering components should also be considered before putting the car back on the road. A well-restored Bentley benefits from fitment that looks right and functions properly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Bentley Mulsanne?
Yes. Modifications can affect tire fitment on a 1989 Bentley Mulsanne even when the tire size remains 235/70R15. Changes such as aftermarket wheels, different wheel widths, altered offset, suspension work, or body adjustments can all influence how the tire sits and clears the car.
That matters because a correct size code alone does not guarantee the same result on every car. A Mulsanne with non-original wheels or suspension changes should be checked for inner and outer clearance, steering movement, and wheel-width compatibility before a new set of tires is chosen.
What should I inspect before driving a 1989 Bentley Mulsanne on new tires?
Before driving a 1989 Bentley Mulsanne on new tires, inspect the wheels for damage or corrosion, confirm the wheel size, and make sure the tires are seated and inflated properly. It is also wise to look over suspension and steering components so the new tires are not being asked to compensate for worn hardware.
A collector Bentley may spend long periods parked, so road readiness goes beyond mounting fresh rubber. Check for alignment issues, uneven old tire wear, fluid leaks onto the tires, and any rubbing through full steering travel. A careful inspection helps the new 235/70R15 tires perform as intended.
How should 235/70R15 tires on a collector 1989 Bentley Mulsanne be maintained?
235/70R15 tires on a collector 1989 Bentley Mulsanne should be maintained with regular pressure checks, visual inspections, and periodic movement of the car to avoid long-term flat spotting. Tread condition, sidewall cracking, cuts, bulges, and slow air loss all deserve attention even if the car is driven infrequently.
Storage conditions also matter on a luxury car that may see seasonal use. Keeping the Bentley away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. Before any longer outing, inspect all four tires again rather than assuming low mileage means low risk.
