The 1998 Bentley Azure sits in a distinctive corner of late twentieth-century luxury motoring, blending hand-built Bentley presence with open-top grand touring character. Owners tend to value these cars for their effortless road manners, substantial scale, and the special feel that comes with a bespoke convertible from Crewe. Tire selection matters because the 1998 Bentley Azure uses radial fitments in two modern metric sizes, 255/50R18 and 255/55R17, depending on the wheel setup on the car. That makes wheel diameter the first decision, followed by choosing a tire that suits the car’s intended road use and preserves the composed, substantial look expected of an Azure.
Which Tire Size Is Right for The 1998 Bentley Azure
The 1998 Bentley Azure uses two primary tire sizes, and the difference comes down to wheel diameter: 255/50R18 for 18-inch rims or 255/55R17 for 17-inch rims. Both are radial metric fitments, so the first step is confirming which wheels are actually on the car before comparing tire choices, ride profile, and overall presentation.
A 255/50R18 tire uses a 255-millimeter nominal section width, a 50-series aspect ratio, radial construction, and an 18-inch rim diameter. On a 1998 Bentley Azure, this is one of the two primary radial fitments and should be matched to an actual 18-inch wheel rather than assumed from the model alone. The lower-profile metric format gives the buyer a modern sizing reference that is familiar and easy to verify. Choose this size only after confirming the car is equipped with 18-inch wheels and checking that the rest of the wheel and suspension setup remains appropriate for Azure fitment.
A 255/55R17 tire also carries a 255-millimeter nominal section width, but with a 55-series aspect ratio and a 17-inch rim diameter in radial construction. For the 1998 Bentley Azure, this size serves the alternate primary fitment for cars running 17-inch wheels. Its metric radial sizing is straightforward for modern buyers, but the key distinction is the wheel diameter it requires. This size should be evaluated by confirming the wheel itself first, then checking overall vehicle setup so the tire choice matches the Azure’s current wheels and intended road use.
The 1998 Bentley Azure Base uses both primary tire sizes, so fitment is less about trim differences and more about verifying the wheel diameter on the car. Checking whether the car has 17-inch or 18-inch wheels is the key step before choosing tires.

Frequently Asked Questions
Common questions for the 1998 Bentley Azure usually center on the two metric tire sizes, the 17-inch versus 18-inch wheel decision, and what to inspect before putting a heavy luxury convertible back on the road.
Tire Size & Fitment
What tire size fits a 1998 Bentley Azure?
The 1998 Bentley Azure uses two primary tire sizes: 255/50R18 and 255/55R17. Both are radial metric fitments, and both are associated with the Azure Base, so the correct choice depends on which wheel diameter is actually installed on the car.
That means the first job is not guessing by trim name, but confirming the wheels. An 18-inch wheel requires 255/50R18, while a 17-inch wheel requires 255/55R17. Before selecting tires, inspect the wheel markings and compare the current setup carefully, especially if the car has ever been changed from its earlier wheel and tire combination.
What size rim does a 1998 Bentley Azure use?
A 1998 Bentley Azure uses either a 17-inch rim or an 18-inch rim, depending on the tire size on the car. The two corresponding tire fitments are 255/55R17 for a 17-inch wheel and 255/50R18 for an 18-inch wheel.
Rim diameter matters because these two sizes are not interchangeable across the same wheel. A quick visual estimate is not enough on a collector car, particularly one that may have had replacement wheels at some point. Check the wheel itself, then confirm the tire size matches it before moving on to brand, tread pattern, or other tire-selection details.
Why does the 1998 Bentley Azure have more than one tire size?
The 1998 Bentley Azure has more than one tire size because it is associated with two different wheel diameters. The model uses 255/55R17 on 17-inch rims or 255/50R18 on 18-inch rims, with both sizes appearing within the same Azure Base fitment range.
For the buyer, that makes wheel confirmation more important than sub-model identification. A car may still wear one of these wheel setups today, or it may have been changed during its life. Matching the tire to the actual wheel is the foundation, and only after that should overall condition, clearance, and intended road use shape the final tire decision.
Choosing the Right Tire
What should I consider when choosing a 255/50R18 tire for a 1998 Bentley Azure?
Start by confirming that the car truly has 18-inch wheels, because 255/50R18 is only correct for that setup. The size itself tells you the tire is a modern metric radial with a 255-millimeter section width and a 50-series profile intended for an 18-inch rim.
Once the wheel diameter is confirmed, compare the tire’s overall suitability for a large luxury convertible rather than selecting by size alone. Wheel condition, suspension health, alignment, and body clearance all matter on a heavy grand touring car. It also helps to compare the current tire dimensions against what is already on the vehicle before making a change.
What should I consider when choosing a 255/55R17 tire for a 1998 Bentley Azure?
A 255/55R17 tire is one of the correct primary fitments for a 1998 Bentley Azure, but only on a 17-inch wheel. It is a modern metric radial size, so the first decision is verifying the wheel diameter rather than assuming every Azure uses the same tire.
After that, think about how the car is actually used. A Bentley Azure that spends most of its time on occasional touring drives may call for a different overall tire priority than one driven more regularly. Tire age, ride quality expectations, and the condition of the existing wheels should all be reviewed before settling on a replacement in this size.
How do I choose between the available tire sizes for a 1998 Bentley Azure?
You do not choose between 255/50R18 and 255/55R17 as styling alternatives on the same wheel. The correct size is determined by the wheel diameter already fitted to the 1998 Bentley Azure: 18-inch wheels use 255/50R18, and 17-inch wheels use 255/55R17.
That makes this a wheel-confirmation decision first and a tire-selection decision second. Measure or inspect the wheel, then verify that the current setup has adequate clearance and remains appropriate for the car’s suspension and steering range. On a vehicle that may have seen wheel changes over time, that extra check helps avoid ordering a size that belongs on the other rim diameter.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Bentley Azure?
A period-style tire choice for a 1998 Bentley Azure starts with using the correct primary fitment for the wheel on the car: 255/50R18 on 18-inch rims or 255/55R17 on 17-inch rims. Since both are modern metric radial sizes, the visual result depends heavily on keeping the wheel-and-tire proportions appropriate to the Azure’s grand touring character.
Appearance should be judged alongside fitment accuracy, not apart from it. An Azure with the wrong tire size can lose the substantial, composed stance that suits the car. For owners pursuing a highly exact restoration, compare the present wheel setup with marque-specific historical references so the finished look stays consistent with the car’s intended period presentation.
Does correct tire fitment matter for a 1998 Bentley Azure restoration?
Correct tire fitment matters on a 1998 Bentley Azure restoration because the car’s stance, wheel-to-body relationship, and road-going character all depend on using the right size for the installed rim. The two primary fitments share similar overall dimensions, but each belongs to a different wheel diameter.
Restoration-minded owners should treat tire fitment as both a visual and mechanical decision. A car restored with the wrong rim-and-tire combination can look slightly off even when the mistake is hard to spot at first glance. Confirming wheel diameter, checking suspension condition, and matching the tire size to the actual setup help preserve the Azure’s intended presence.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Bentley Azure?
Yes, modifications can affect tire fitment on a 1998 Bentley Azure. Even though the primary sizes are 255/50R18 and 255/55R17, changes such as aftermarket wheels, altered wheel offset, suspension work, or body modifications can influence how those sizes sit within the wheel openings and steering range.
That is why a modified Azure should be checked as an individual car before replacement tires are chosen. Verify wheel diameter first, then inspect width, clearance at full steering lock, and the relationship between the tire and fender or suspension components. Those checks matter even when the tire size itself appears to match one of the standard Azure fitments.
What should I inspect before driving a 1998 Bentley Azure on new tires?
Before driving a 1998 Bentley Azure on new tires, inspect the wheels for damage or corrosion, confirm the tire size matches the actual rim diameter, and look over the suspension and steering components for wear. On a heavy luxury convertible, alignment condition also deserves attention before regular road use resumes.
The tires themselves should be checked for proper inflation, secure valve hardware, and any early signs of air loss after installation. It also helps to drive the car carefully at first and watch for vibration, pulling, or unexpected clearance issues. Those observations can reveal wheel or chassis issues that the old tires may have been masking.
What should I check before a longer drive in a 1998 Bentley Azure?
Before a longer drive in a 1998 Bentley Azure, confirm that the tires are the correct 255/50R18 or 255/55R17 size for the wheels on the car and that inflation is set appropriately for the vehicle’s use. Inspect tread and sidewalls for cracking, bulges, cuts, or uneven wear before setting off.
A longer outing also makes it worthwhile to review the age and general condition of the tires, especially on a collector car that may sit for extended periods. Pay attention to wheel security, steering feel, and any signs of vibration during the first miles. Catching those issues early can prevent a short local problem from becoming a highway interruption.
