1973 Bentley Tire Fitment Guide

1973 Bentley vehicles in this range use one tire size: 205R15. It applies to the 1973 Bentley T Series, and the products available in that size mount on 15-inch wheels. Rim width guidance is present for the Phoenix version of 205R15 at 5.50 to 6.00 inches, which is a useful benchmark when checking wheel compatibility.

That single-size setup makes the year and make much easier to sort out than a mixed model range with several fitments. Even so, it is still wise to confirm the actual wheel diameter on the car and compare the wheel width to the tire manufacturer's approved range before committing to a tire, especially on a restored or long-owned Bentley that may have seen wheel changes over time.

On a 1973 Bentley, 205R15 is a euro-metric radial size. The 205 refers to a nominal section width of 205 millimeters, the R identifies radial construction, and the 15 is the wheel diameter in inches. Because this code does not state an aspect ratio, it is conventionally treated as an 80-series radial.

That matters because 205R15 is a distinctly modernized sizing format compared with older numeric or bias-ply designations. For a Bentley T Series, it points you toward a touring-oriented radial that suits the car's luxury character, but you should still compare sidewall style, speed rating, and approved wheel width before choosing between available versions of the same size.

Yes. The 1973 Bentley range covered here uses one tire size across the board: 205R15, and that fitment applies to the T Series. There is no year-specific split between one model using a different diameter or a different construction type, so the baseline fitment question is straightforward.

That does not mean every owner will choose the same tire presentation. Some Bentley owners prefer a wide whitewall for a more formal period look, while others want a blackwall to keep the car visually restrained. Once you know the car is a 1973 Bentley T Series on 15-inch wheels, the decision becomes more about style and intended use than about sorting through multiple factory size options.

1973 Bentley tires in 205R15 are available in both wide whitewall and blackwall form. Phoenix offers the size with a 2.50-inch whitewall, while Avon offers the same size as a blackwall. Both are radial tires, so the visual difference is more significant here than a change in construction type.

For a Bentley of this era, sidewall style can shape the car's presence almost as much as wheel finish. A wide whitewall leans into the formal luxury character many owners associate with traditional British saloons, while a blackwall gives the T Series a cleaner, more understated touring look. Matching the sidewall to your restoration goal is usually more important here than chasing a different size.

Phoenix and Avon both make 205R15 tires for 1973 Bentley vehicles. Phoenix offers a wide whitewall radial, and Avon offers a blackwall radial in the same size. That gives Bentley owners a choice between two established names while staying within the proper 15-inch radial fitment.

Brand choice often comes down to the way you want the finished car to look and how closely you want to align with a European luxury-touring feel. Avon has long been associated with premium British and European applications, while Phoenix is often chosen when whitewall presentation is part of the visual goal. Choosing between them is less about changing fitment and more about matching the tire to the car's character.

For the 1973 Bentley, both Phoenix and Avon are available in 205R15 radial form, but they differ in presentation and some published specifications. The Phoenix tire uses a 2.50-inch wide whitewall, weighs 26 pounds, and fits a 5.50 to 6.00-inch rim width range. The Avon Turbosteel is a blackwall, weighs 25 pounds, and carries a 97V marking, which includes a V speed rating with a 149 mph ceiling.

That comparison makes the choice fairly clear for most owners. Phoenix suits a more formal visual restoration where whitewall presence matters, while Avon suits owners who want a blackwall radial with an explicitly marked speed rating. Either way, the tire remains the same base size, so your decision is mainly about appearance and the character you want the Bentley to project on the road.

A 1973 Bentley tire in 205R15 has a published rim width range of 5.50 to 6.00 inches for the Phoenix radial. All 205R15 options here use a 15-inch rim diameter, so diameter compatibility is consistent across the fitment. Wheel width still matters because it affects sidewall shape, tread behavior, and overall fit on the car.

The smart approach is to measure the actual wheel before choosing a tire, especially on a classic Bentley that may have had replacement or refinished wheels over the years. If your wheel falls within the approved width range, you are on much firmer ground. If not, move carefully and compare the exact tire's specifications rather than assuming every 205R15 will behave the same way on every 15-inch wheel.

The 205R15 tires available for 1973 Bentley do not carry tube-type markings in their size descriptions, and both are modern radial products. That points buyers toward tubeless-style fitments rather than a traditional tube-type collector tire setup. The deciding factor, however, is the wheel condition and whether the wheel itself is suitable for tubeless service.

Older wheels can have corrosion, pitting, or design features that affect air retention even when the tire itself is built for tubeless use. A careful inspection of the rim, valve stem area, and bead seat is worth doing before mounting new tires. If the wheels have been restored or the car has sat for a long period, having a knowledgeable vintage tire installer inspect them is time well spent.

A 1973 Bentley stores best in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing sources. Maintain normal inflation, keep the car off damp ground, and move it periodically so the tires do not sit in one contact patch for months at a time. Radial tires generally tolerate storage better than bias-ply tires, but they still age from time, heat, and environment.

For a long-term parked car, many owners either roll the Bentley occasionally or use stands placed correctly to reduce continuous load. Tire covers can help if the storage area has light exposure, but clean, stable indoor conditions matter more than accessories. If the car is part of a collection and driven infrequently, storage discipline often does more for tire life than low mileage ever will.

Tires on a 1973 Bentley should be judged more by age and condition than by tread wear alone. A useful rule is to begin evaluating them closely once they reach five to seven years of service and to treat about ten years as a point where replacement deserves serious consideration regardless of miles traveled. The DOT date code on the tire sidewall is the quickest way to verify age.

Collector Bentleys often see gentle use, which can make old tires look deceptively healthy even when the rubber compound has hardened. Sidewall cracking, vibration, flat spotting that does not clear, or a loss of wet-road confidence are all signs that age is becoming the real issue. A low-mileage classic can still need new tires long before the tread appears worn out.

Tires on a 1973 Bentley should be inspected before every drive and given a more careful check before any extended outing. Look for sidewall cracking, cuts, bulges, embedded debris, uneven tread wear, and signs of pressure loss. Because this is a heavy luxury car from an earlier era, catching a tire issue early is especially important to preserve ride quality and road manners.

A monthly pressure check is a good habit even when the Bentley is not being driven often. Before a tour or weekend trip, inspect the spare as well, since a spare that is decades old may not be trustworthy even if it has never touched the road. If you notice new vibration or a pull that was not there before, do not assume it is just an old-car quirk.

A 1973 Bentley T Series belongs to an era when radial tires were already established for luxury European saloons, and the 205R15 fitment reflects that. The available replacements for this year and model are radial tires in that same basic size family. That makes radial construction the historically appropriate starting point when restoring or maintaining a T Series.

Original-equipment branding could vary by market, delivery region, and period supplier relationships, so owners chasing exact factory-level authenticity should confirm details through Bentley marque clubs, factory literature, or long-established specialists. For most restorations, getting the correct size, proper 15-inch fitment, and the right sidewall appearance will matter more than trying to force a different construction that does not suit the period.

Yes, correct tire fitment matters on a 1973 Bentley if the car is judged for authenticity. Judges and knowledgeable enthusiasts will often notice whether the size, construction type, and sidewall presentation suit the era and the character of the model. On a formal British luxury saloon, an obviously incorrect diameter or an out-of-place sidewall treatment can distract from an otherwise careful restoration.

That does not mean every event uses the same standard. Some concours venues care deeply about period-correct appearance, while touring events may be more relaxed if the tire is the proper size and looks appropriate on the car. If you are building the Bentley for judged competition, check event rules and consult Bentley club experts before choosing between blackwall and wide whitewall presentations.

In restoration terms, the main difference is visual character. Phoenix offers the 205R15 as a wide whitewall radial, while Avon offers the same size as a blackwall radial with a 97V marking. The Phoenix tire also carries a published rim width range of 5.50 to 6.00 inches and weighs 26 pounds, while the Avon weighs 25 pounds.

For many restorers, the decision comes down to which look best matches the Bentley they are presenting. A wide whitewall creates a more ceremonial, traditional luxury appearance, while a blackwall tends to look more restrained and European. Neither changes the basic size fitment, so the restoration question is usually one of authenticity and visual intent rather than one of mechanical compatibility.

Yes, 1973 Bentley tires can be suitable for highway driving when they are the correct size, in sound condition, and properly maintained. The available 205R15 fitment is radial, and the Avon version carries a V speed rating, which corresponds to a 149 mph ceiling. In normal U.S. highway use, the broader condition of the tire and the health of the Bentley's suspension, steering, and brakes matter at least as much as the speed symbol.

A well-kept Bentley T Series is a relaxed touring car, but age changes the equation on any collector vehicle. Old rubber, underinflation, or long storage can make even a correctly sized tire a poor highway companion. Before any sustained road use, make sure the tires are not simply adequate on paper but genuinely roadworthy in the real world.

For 1973 Bentley tires, use the vehicle manufacturer's recommended cold inflation pressure as your primary starting point, then confirm that the tire itself is being operated within its own rated limits. The 205R15 Phoenix tire carries a maximum load of 1609 at 34 psi, and the Avon 205R15 carries a maximum load of 1,609 pounds. Those figures describe the tire's load-capacity point, not necessarily the exact pressure the Bentley should run in routine service.

That distinction matters because factory pressure recommendations are tied to the car's weight distribution, ride quality, and handling balance. A reproduction or specialty radial can have a different construction feel than a mid-1970s original-equipment tire even in the same size. Check the owner's literature first, then fine-tune only within the tire maker's approved guidance rather than copying a pressure from a different size or a different vehicle.

Before a longer drive in a 1973 Bentley, inspect each tire for cracking, cuts, bulges, irregular wear, embedded objects, and proper cold inflation pressure. Check valve stems, confirm that the tread area is wearing evenly, and make sure the spare is present and serviceable. A Bentley that looks immaculate can still hide age-related tire issues if it spends more time stored than driven.

Tires are only one part of the pre-drive routine on a 1970s luxury car, so pair that inspection with a broader check of brakes, fluids, steering response, and suspension condition. The T Series was built for refined road use, but refinement depends on every system working together. A calm highway trip usually starts with patient garage-time inspection rather than trying to discover problems after departure.
