The 1997 Bentley Continental sits in the modern coachbuilt grand touring tradition, blending imposing presence with the kind of effortless high-speed character Bentley was known for in the 1990s. For owners today, tire selection is less about vintage-style construction and more about matching the exact Continental variant to the correct modern radial fitment. The 1997 Bentley Continental R uses 255/55R17, while the more aggressive Continental T uses 285/45R18. That means the real decision starts with identifying the sub-model, then confirming wheel diameter before comparing tire design, road-use priorities, and overall fitment on a car that may have seen wheel or suspension changes over time.
Which Tire Size Is Right for The 1997 Bentley Continental
The 1997 Bentley Continental uses two primary tire sizes, and the correct choice depends on the exact sub-model. The Continental R uses a 17-inch radial fitment, while the Continental T uses an 18-inch radial fitment, so confirming both the model variant and wheel diameter is the first step before comparing tire options or checking any modified wheel setup.
255/55R17 is a metric radial size in which 255 identifies the nominal section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 17 is the wheel diameter in inches. On the 1997 Bentley Continental, this size is associated with the Continental R and reflects a modern performance-touring fitment rather than an older bias-ply convention. Its dimensions suit a large luxury coupe that still needs proper wheel and clearance matching. This is the size to evaluate if the car is an R model with its original 17-inch wheel setup or a confirmed equivalent wheel package.
285/45R18 is a metric radial size where 285 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 1997 Bentley Continental, this size belongs to the Continental T and represents a wider, lower-profile fitment on an 18-inch rim. That makes wheel confirmation especially important before replacement, particularly on cars that may have had aftermarket wheels installed. This is the size to focus on when the vehicle is a Continental T and the current wheel diameter remains 18 inches.
Tire fitment for the 1997 Bentley Continental varies by sub-model rather than staying uniform across the range. Checking whether the car is a Continental R or Continental T matters first, because each uses a different radial size and wheel diameter.

1997 Bentley Continental R
The 1997 Bentley Continental R uses a 255/55R17 radial tire. Tire selection for the R starts with confirming the 17-inch wheel setup, then choosing a replacement that matches the car's intended road use, ride character, and overall fitment.
The 1997 Bentley Continental T uses a 285/45R18 radial tire. For the T, the key step is verifying the 18-inch wheel configuration and making sure width, clearance, and suspension condition are all in order before selecting a replacement tire.
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 1997 Bentley Continental usually center on identifying the correct tire size by sub-model, confirming 17-inch versus 18-inch wheel fitment, and checking condition, clearance, and maintenance before putting a heavy luxury coupe back on the road.
Tire Size & Fitment
What tire size fits a 1997 Bentley Continental?
A 1997 Bentley Continental uses one of two radial tire sizes depending on the sub-model. The Continental R uses 255/55R17, while the Continental T uses 285/45R18. Both are modern metric radial sizes, but they are not the same fitment and they do not use the same wheel diameter.
The practical first step is identifying whether the car is an R or a T, then confirming the wheels currently on the car. If a previous owner changed wheel diameter, width, or suspension height, the original sub-model fitment is still the reference point, but actual clearance and wheel compatibility should be checked before choosing replacement tires.
What size rim does a 1997 Bentley Continental use?
Rim diameter depends on the specific 1997 Bentley Continental sub-model. The Continental R uses a 17-inch rim with its 255/55R17 tire size, while the Continental T uses an 18-inch rim with its 285/45R18 tire size. That means wheel diameter is tied directly to the correct tire selection.
Measuring or confirming the wheel already on the car is important before ordering tires, especially on a vehicle that may have received aftermarket wheels over time. Even when the sub-model is known, the actual wheel width, condition, and available clearance around suspension and bodywork should be reviewed so the replacement tire matches the setup on the car.
Do all 1997 Bentley Continental sub-models use the same tire size?
No, the 1997 Bentley Continental sub-models do not share the same tire size. The Continental R uses 255/55R17, and the Continental T uses 285/45R18. Both are radial tires, but they differ in width, aspect ratio, and rim diameter, so they represent two distinct fitments within the same model line.
That difference matters because a buyer cannot choose tires by year and model name alone. The sub-model has to be confirmed first, and the current wheel setup should match it. On cars with changed wheels or suspension, the original fitment remains a useful guide, but actual dimensions and clearance should be verified before putting the car back into regular road use.
Choosing the Right Tire
What should I consider when choosing a 255/55R17 tire for a 1997 Bentley Continental?
For a 1997 Bentley Continental fitted with 255/55R17, the main considerations are confirming that the car is a Continental R, verifying the wheel is still 17 inches in diameter, and making sure the tire's overall size suits the car's existing setup. Since this is a modern radial fitment, proper wheel compatibility is central to the selection process.
A careful inspection of wheel width, suspension condition, and surrounding clearance is worthwhile before replacement, especially on a large luxury coupe that may have seen modifications over the years. Tire age and condition also matter if the car is driven infrequently, because low mileage does not prevent weathering, flat-spotting, or sidewall deterioration from becoming a road-use concern.
What should I consider when choosing a 285/45R18 tire for a 1997 Bentley Continental?
On a 1997 Bentley Continental using 285/45R18, the first priority is confirming that the car is a Continental T and that it still carries the correct 18-inch wheel setup. This size combines a wider tread section with a lower profile than the Continental R fitment, so wheel and body clearance deserve close attention.
Selection should also take the car's real-world use into account, whether it is driven occasionally, stored for long periods, or exercised more regularly. Checking wheel condition, alignment, and suspension wear helps prevent fitment surprises, and it is wise to confirm there is no rubbing at full steering lock or under compression before relying on the car for longer trips.
How do I choose between the available tire sizes for a 1997 Bentley Continental?
Choosing between the available tire sizes for a 1997 Bentley Continental is not a matter of preference; it starts with the correct sub-model. The Continental R uses 255/55R17, while the Continental T uses 285/45R18. Those sizes correspond to different wheel diameters and should be treated as separate fitment paths rather than interchangeable options.
Once the correct sub-model is confirmed, the next step is to compare that original fitment with the wheel and suspension setup currently on the car. A Bentley that has been altered over time may still need careful measuring before replacement. Matching the tire to the actual wheel, clearance, and intended road use is more important than choosing between the two sizes abstractly.
Restoration & Appearance
Which tire should I choose for a period-style 1997 Bentley Continental?
A period-style 1997 Bentley Continental should begin with the correct sub-model fitment rather than a generalized size choice. That means 255/55R17 for the Continental R and 285/45R18 for the Continental T. Because this is a late-1990s Bentley, the correct visual impression comes from retaining the proper modern radial proportions and wheel diameter for the specific variant.
Appearance on a car of this era depends heavily on stance and scale, so incorrect diameter or profile can change the look quickly. Owners pursuing a restoration-oriented result should compare the current wheel setup to the original sub-model specification, then confirm that tire dimensions preserve the intended visual balance without creating clearance issues or an obviously altered presentation.
Does correct tire fitment matter for a 1997 Bentley Continental restoration?
Yes, correct tire fitment matters on a 1997 Bentley Continental restoration because tire size has a strong effect on stance, wheel-to-body proportion, and the overall character of the car. The Continental R and Continental T do not share the same size, so using the correct radial fitment for the exact variant is part of getting the finished presentation right.
That matters both visually and practically. A tire that departs from the proper wheel diameter or profile can alter the car's look and may also create avoidable fitment issues. For an owner trying to restore the car thoughtfully, confirming sub-model, wheel diameter, and current chassis setup is a better starting point than choosing a tire only by general Bentley application.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1997 Bentley Continental?
Yes, modifications can affect tire fitment on a 1997 Bentley Continental even when the car started with the correct factory-size reference for its sub-model. Aftermarket wheels, altered wheel widths, changes in offset, lowering, suspension work, or body modifications can all change how a 255/55R17 or 285/45R18 tire sits within the available space.
That is why the current setup should be checked instead of assuming the original sub-model fitment still tells the whole story. Wheel diameter, width, and clearance at the fender, suspension, and steering components all deserve attention. On a heavy grand touring coupe, even small changes can affect rubbing risk, steering clearance, and the overall confidence of the fitment.
What should I inspect before driving a 1997 Bentley Continental on new tires?
Before driving a 1997 Bentley Continental on new tires, inspect the wheels for damage, confirm the tire size matches the correct sub-model, and make sure inflation is set appropriately for the tire and vehicle use. It is also wise to look over suspension and steering components, since worn parts can affect how a new tire behaves on the road.
A short local drive is a sensible first check after installation. Listen for rubbing, feel for vibration, and verify the car tracks properly without unusual pull or noise. Rechecking air pressure after the first drives, along with a visual look for any contact marks, helps catch setup problems early before they become expensive or compromise road confidence.
How should tires on a collector 1997 Bentley Continental be maintained?
Tires on a collector 1997 Bentley Continental should be maintained with regular pressure checks, periodic visual inspection, and careful storage habits. Even if the car is driven sparingly, tires can age from time, heat, sunlight, and ozone exposure. Sidewall cracking, flat spotting, tread separation signs, bulges, cuts, and slow air loss all deserve attention.
Collector cars benefit from more than mileage-based thinking. A Bentley that sits for extended periods should be moved or repositioned occasionally, stored in a clean and dry environment, and checked before any longer outing. Looking closely at both tire condition and wheel condition is especially important on a heavy luxury coupe, where neglected maintenance can show up quickly once road speeds increase.
