In 2000 Bentley stood at an interesting crossroads, blending traditional British luxury with modern grand touring expectations. The range spanned the stately Arnage sedan and the long-running Azure and Continental coupes and convertibles, all of them heavy, powerful cars that ask more of their tires than earlier Bentleys ever did. Across 2000 Bentley models, three radial tire sizes appear, with the Arnage using one shared size and the Azure and Continental using a broader mix that includes both 17-inch and 18-inch fitments. The first step is confirming your exact model, then verifying whether your car is meant to run the narrower 255-section size or the wider 285/45R18 rear fitment.
Which Tire Size Is Right for Your 2000 Bentley
Three tire sizes are used across 2000 Bentley vehicles, and they vary by model rather than carrying across the whole range. The main decision is confirming your exact Bentley model first, then confirming whether your car uses a 17-inch or 18-inch wheel and whether it calls for the wider 285-section fitment. Understanding that distinction before choosing a product saves time and helps match the tire to the car correctly.
Year(s): 2000|Fit(s): Arnage, Azure, Continental|Construction: Radial|Rim: 18-in rim
255/50R18 is a radial metric size with a 255 millimeter section width, a 50-series aspect ratio, and an 18-inch rim diameter. This size serves all three 2000 Bentley models covered here, making it the one shared fitment across the year and make. For buyers comparing across the range, it is the common 18-inch size to confirm first before narrowing down product style and exact application.
Year(s): 2000|Fit(s): Azure, Continental|Construction: Radial|Rim: 17-in rim
255/55R17 is a radial metric size with a 255 millimeter section width, a 55-series aspect ratio, and a 17-inch rim diameter. This fitment is specific to the 2000 Bentley Azure and 2000 Bentley Continental rather than the full model range. It is the size to choose when your car is equipped for the 17-inch application used on those grand touring models, so the wheel diameter should be confirmed before moving any further.
Year(s): 2000|Fit(s): Azure, Continental|Construction: Radial|Rim: 18-in rim
285/45R18 is a radial metric size with a 285 millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. This size is specific to the 2000 Bentley Azure and 2000 Bentley Continental, and its wider section sets it apart from the 255-width options used elsewhere in the range. It is the size to confirm when your Bentley uses the broader 18-inch fitment associated with those models rather than the shared Arnage size.
Three Bentley models are covered for the 2000 model year. Tire size is not uniform across the range, so identifying whether you have an Arnage, Azure, or Continental matters before choosing a tire size. Select your model below to narrow the fitment history and see the tire options that apply to that specific Bentley.
2000 Bentley Arnage
The 2000 Bentley Arnage carried Bentley into the modern luxury-sedan era while keeping the marque's familiar sense of weight, presence, and long-distance refinement. Its tire fitment here stays focused on an 18-inch application, which simplifies selection compared with the broader grand touring Bentley range.
The 2000 Bentley Azure was a large, hand-built luxury convertible aimed at effortless high-speed touring with traditional Bentley character. Its fitments span both 17-inch and 18-inch wheels, including a wider 285/45R18 application, so confirming the exact wheel setup is especially important on this model.
The 2000 Bentley Continental continued the marque's long-running formula of high-speed luxury coupe motoring, combining substantial curb weight with serious grand touring intent. Like the Azure, it uses both 17-inch and 18-inch tire applications in this model year, including the wider 285/45R18 size on certain setups.
These FAQs cover how the three radial sizes are split across the 2000 Bentley range, what the metric size codes mean, and what to confirm before fitting tires to an Arnage, Azure, or Continental that may see collector use rather than daily mileage.
Size Basics & Fitment
What tire sizes fit 2000 Bentley vehicles?
Three tire sizes fit 2000 Bentley vehicles in this range: 255/50R18, 255/55R17, and 285/45R18. The 255/50R18 fits the 2000 Bentley Arnage, Azure, and Continental. The 255/55R17 and 285/45R18 fit the 2000 Bentley Azure and 2000 Bentley Continental, but not the Arnage. That means the year and make alone are not enough to choose correctly across the whole Bentley lineup.
Identifying the model is the first step, and wheel diameter comes next. The 255/55R17 mounts on a 17-inch wheel, while the 255/50R18 and 285/45R18 mount on 18-inch wheels. If you are working from an existing car rather than factory paperwork, verify the tire size already on the car and check the actual wheel before choosing a replacement.
What does 255/50R18 mean on a 2000 Bentley tire?
On a 2000 Bentley, 255/50R18 means the tire is 255 millimeters wide, has a 50-series aspect ratio, uses radial construction, and fits an 18-inch wheel. It is a modern metric radial size rather than an older numeric or alphanumeric collector-car code. Among 2000 Bentley models, this size is the shared fitment used by the Arnage, Azure, and Continental.
That shared use makes 255/50R18 the easiest place to start when you know the year and make but still need to confirm the exact model. Even so, the size code must still match the wheel on the car. An 18-inch metric radial cannot be substituted onto a 17-inch wheel, and a wider 285-section tire serves a different fitment role on Azure and Continental applications.
Do all 2000 Bentley models use the same tire size?
No, not all 2000 Bentley models use the same tire size. The Arnage uses 255/50R18, while the Azure and Continental can use 255/50R18, 255/55R17, or 285/45R18 depending on the application. That split reflects the difference between the Arnage luxury sedan and the Azure and Continental grand touring models, which span more than one wheel and tire setup.
If your Bentley is an Azure or Continental, confirming the model alone may still not be enough; you should also verify the wheel diameter and whether the car uses the wider 285/45R18 fitment. Owners of an Arnage have a more straightforward path because only one size applies here. A quick check of the sidewall marking and wheel diameter usually settles the question.
Buying the Right Tire
What sidewall styles are available for 2000 Bentley tires?
All three sizes used on 2000 Bentley vehicles are modern radial fitments, so the sidewall appearance typically follows a later grand touring luxury-car look rather than an early collector-car bias-ply look. On a car from this era, buyers usually focus more on maintaining the correct overall stance, width, and wheel diameter than on recreating a prewar or 1950s sidewall treatment.
That matters most on the Azure and Continental, where the visual difference between a 255-width tire and a wider 285-width tire can change the car's stance noticeably. For a cleaner, more authentic appearance, keep the sidewall style and overall tire profile appropriate to a 2000 Bentley rather than trying to imitate an earlier-period look. The best approach is to confirm the correct size first, then compare the available sidewall presentation within that size.
How do I choose the right tire size for a 2000 Bentley Azure or 2000 Bentley Continental?
Choosing the right tire size for a 2000 Bentley Azure or 2000 Bentley Continental starts with matching the size already specified for the car: 255/50R18, 255/55R17, or 285/45R18. All three are radial sizes, so the decision is not about bias-ply versus radial construction. It is about confirming the correct wheel diameter and whether the car uses the wider 285-section 18-inch fitment.
The practical check is simple: read the current tire sidewall, confirm the wheel diameter, and compare front and rear sizes if the car has a staggered setup. A 17-inch tire and an 18-inch tire are not interchangeable, and a 285-width tire should not be treated as a substitute for a 255-width tire without verifying the intended application. On these Bentleys, correct size selection supports the car's appearance and intended road manners.
Fitting & Setup
Do 2000 Bentley tires require inner tubes?
The tire sizes used on 2000 Bentley vehicles are modern radial fitments, which are commonly associated with tubeless wheel and tire practice, but the final answer depends on the exact tire and wheel combination you are using. Tube use can vary by product and by wheel design, especially on specialty or replacement wheel setups. That means the tire's sidewall marking and the wheel's construction both matter.
If your Bentley still uses its original style wheels, verify whether the wheel is intended for tubeless service before fitting a tire. If a specific tire is marked in a way that calls for a tube, follow that requirement rather than assuming all products in the same size are identical. On a heavy luxury car such as a 2000 Bentley, matching tube practice to the exact tire and wheel is part of responsible setup.
Can the original 2000 Bentley wheels be used with all tire sizes?
Original 2000 Bentley wheels can only be used with tire sizes that match their rim diameter. The 255/55R17 fits a 17-inch wheel, while the 255/50R18 and 285/45R18 fit 18-inch wheels. That means a wheel sized for one of the 18-inch fitments cannot accept the 17-inch tire, and a 17-inch wheel cannot accept either 18-inch tire.
Azure and Continental owners should pay especially close attention here because those models span more than one diameter. If your Bentley currently wears 18-inch wheels, you still need to confirm whether the intended fitment is the 255/50R18 or the wider 285/45R18. Keeping the original wheel is often possible, but only when the tire size matches the wheel diameter and the wheel is appropriate for that exact application.
Maintenance, Storage & Longevity
How should I store a 2000 Bentley when the tires are fitted?
A 2000 Bentley should be stored on clean, properly inflated tires in a cool, dry, dark environment away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Even modern radial tires age faster when they sit in heat or near ozone sources. Long periods of static storage can also create temporary flat-spotting, especially on a heavy luxury car.
Moving the car occasionally, changing the tire's contact patch, and keeping weight distribution from staying fixed for months at a time all help. For longer layups, many collectors place the car on stands or storage cradles after confirming a safe lifting method for the chassis. If your Bentley is driven only seasonally, proper storage can matter as much as mileage in preserving the tires.
How long do tires on a 2000 Bentley typically last?
Tires on a 2000 Bentley usually age out before they wear out, especially on collector-driven cars. A good rule is to begin close evaluation around five to seven years from the tire's manufacturing date and to treat about ten years as the point where replacement deserves serious consideration, even if tread depth still looks acceptable. The DOT date code on the tire sidewall tells you when the tire was made.
That age-based approach is more useful than mileage on an Arnage, Azure, or Continental that may spend much of its life indoors or on occasional tours. Rubber hardens over time, and internal aging is not always obvious from tread appearance alone. If the car is new to you, checking the date code is one of the first things to do before assuming the tires are road-ready.
How often should tires on a 2000 Bentley be inspected?
Tires on a 2000 Bentley should be inspected before every drive and again before any extended highway outing. Look for sidewall cracking, tread wear, cuts, punctures, bulges, irregular shoulder wear, and any sign that a tire is losing pressure between drives. On a heavy, high-speed-capable luxury car, small tire issues can become large problems quickly once heat and speed build.
A more thorough inspection every few months is wise even if the Bentley is seldom driven. Check pressures cold, inspect valve stems, and look at the spare as well as the four tires on the ground. If the car has been sitting for a long period, pay close attention to vibration on the first drive and recheck the tires afterward for any signs of age-related distress.
Safety & Road Use
Are 2000 Bentley tires safe for highway driving?
2000 Bentley tires use modern radial size formats, which are entirely appropriate for highway use when the tires are in good condition, correctly inflated, and matched to the proper wheel. Safety on the highway depends not just on the size code but on the age and condition of the tire, the exact product's speed rating, and the condition of the vehicle itself. On a 2000 Bentley, suspension condition, brake performance, and alignment are just as important as the tire itself.
For practical road use, confirm that the tire's speed rating suits the way the car will be driven and that all four tires are sound and evenly worn. If the Bentley has older tires with plenty of tread but advanced age, replacement is usually the smarter decision before long-distance highway use. A well-maintained Arnage, Azure, or Continental can be an excellent road car, but tire age and setup should never be treated casually.
What inflation pressure should I use for 2000 Bentley tires?
Inflation pressure for 2000 Bentley tires should follow the factory recommendation for the car and the tire manufacturer's limits for the exact tire size and product you choose. The correct pressure is not something to transfer casually from one size to another, because 255/55R17, 255/50R18, and 285/45R18 are different fitments with different operating characteristics. Pressure should always be checked cold.
Start with the Bentley owner's manual, door-jamb placard if present, or a marque specialist's guidance for your exact model and wheel setup. Then compare that figure with the maximum pressure marking on the tire sidewall so you understand the tire's rated limit. If your car uses different front and rear sizes or load conditions, confirm each axle's recommendation rather than assuming one all-around number.
What should I check before taking a 2000 Bentley on a longer drive?
Before taking a 2000 Bentley on a longer drive, inspect each tire for cracking, cuts, bulges, uneven wear, embedded debris, and proper cold inflation pressure. Check the valve stems, confirm the spare is usable, and make sure the tire size on the car matches the intended setup for the model. Because Azure and Continental fitments can involve more than one size, it is also wise to confirm that the car is wearing the correct 17-inch or 18-inch combination.
A longer drive is also the right time to look beyond the tires. Wheel torque, suspension condition, brake feel, and alignment all affect how a large, powerful Bentley behaves on the road. If the car has been sitting for months, take a short local drive first and recheck pressures and vibration before committing to highway mileage. That extra step can catch age-related tire issues early.
