Bentley T Tires
Bentley T marked a pivotal moment for Crewe, pairing traditional Bentley craftsmanship with the modernized engineering direction of the marque’s late 1960s and 1970s saloon era. Produced here from 1966 through 1976, Bentley T sits in a period where ride quality, road manners, and visual character all influence the right tire choice. Tire selection is not entirely straightforward because the fitments span older numeric bias-ply sizing, a metric radial option, and a later alphanumeric radial size even though the wheel diameter remains consistent. For a Bentley T, the first job is to verify the exact model year and the tire type already fitted so the replacement matches the car’s intended stance and driving character.
Bentley T Tire Size Guide
Bentley T uses 3 distinct tire sizes across the 1966 to 1976 production span. All listed fitments use a 15-inch rim, but the sizing language changes during production from numeric bias-ply sizing to metric and alphanumeric radial formats. That matters because the code itself tells you not just width and profile conventions, but also whether the tire reflects an earlier period-correct bias-ply approach or a later radial construction.
815-15 is the early Bentley T fitment used from 1966 through 1972 on cars specified for this numeric bias-ply size. In this numeric format, 815 indicates a nominal section width of about 8.15 inches and 15 is the rim diameter, with available products fitting 15-inch wheels in the 5.00 to 6.50 inch rim-width range. Choose this size when preserving the earlier bias-ply look and feel of the car; A tube is required.
205R15 appears for 1972 Bentley T models where a radial fitment is listed alongside the earlier numeric size. In this euro-metric radial format, 205 is the section width in millimeters, R identifies radial construction, and 15 is the rim diameter, with listed products fitting 15-inch wheels and one product specifying a 5.50 to 6.00 inch rim-width range. Choose this size when the car is set up for the radial option listed for 1972, and confirm the existing tire type and wheel specification before changing from a bias-ply setup.
HR70-15 is the later Bentley T fitment shown for 1976 and represents a different sizing convention from the earlier listings. In this alphanumeric radial format, H identifies the tire’s width and load class, R marks radial construction, 70 is the aspect series, and 15 is the rim diameter. Choose this size for a 1976 Bentley T using the later radial specification, and verify the exact marking on the current tire or original vehicle paperwork before substituting another size.
Bentley T Tires by Year
The year listing shows which tire sizes are associated with each Bentley T model year so you can narrow the choices before reviewing individual products. In 1972, more than one size is listed, reflecting a construction split between numeric bias-ply and radial fitments. These listings cover a relatively short production span, so it is wise to confirm the exact car against original vehicle paperwork or a marque specialist before choosing a tire.

Frequently Asked Questions
The FAQ below focuses on the Bentley T’s shift from numeric bias-ply sizing to radial formats, the two-size overlap in 1972, and the practical differences between period-style and later-construction tire choices.
Size Basics & Fitment
Bentley T uses three listed tire sizes across the years covered here: 815-15 for 1966, 1968, 1970, and 1972; 205R15 for 1972; and HR70-15 for 1976. Every listed size uses a 15-inch rim, but the formats differ. The 815-15 fitment is a numeric bias-ply size, 205R15 is a radial metric-style size, and HR70-15 is an alphanumeric radial size.
The practical step is to match the tire to the exact year and to the type already fitted to the car. A 1972 Bentley T needs extra attention because both 815-15 and 205R15 appear in that year, which means you should verify whether the car is set up for the earlier bias-ply specification or the radial alternative before replacing a full set.
On a Bentley T, 815-15 is a numeric bias-ply size. The 815 portion represents a nominal section width of about 8.15 inches, while 15 is the rim diameter in inches. The products listed in this size fit 15-inch wheels and specify a rim-width range of 5.00 to 6.50 inches.
That older numeric code matters because it points to a period-style bias-ply tire rather than a later radial. If your Bentley T is being kept visually and dynamically close to its earlier fitment style, 815-15 is the size to investigate first, and because the available products are bias-ply, tube use should be part of the installation plan.
A 1972 Bentley T has two tire sizes listed because that year includes both 815-15 and 205R15. The split is a construction split rather than a wheel-diameter change, since both sizes use a 15-inch rim. One option is the older numeric bias-ply fitment and the other is a radial fitment using a more modern size convention.
That means year alone is not enough to choose correctly for a 1972 Bentley T. Check the tire markings already on the car, review any original service or ownership records you have, and confirm whether the goal is to preserve the car’s earlier bias-ply character or maintain a radial setup that may already be established.
Bentley T tires in the listed 815-15 size do require tubes because that fitment is offered here as a bias-ply tire with no tubeless indication. The 205R15 radial products are presented as radial passenger-car tires and are not described the same way. Tube use therefore depends on which Bentley T size and construction you are fitting.
For an early Bentley T on 815-15 tires, plan the installation as a tube-type bias-ply setup. For a 1972 car using 205R15 radials, or a later car using radial sizing, confirm the wheel design and current configuration before making any changes, especially if the car has been converted from one tire type to another at some point in its life.
Buying the Right Tire
A 1972 Bentley T is the key year to verify carefully because two sizes are listed for that model year: 815-15 and 205R15. Both fit 15-inch wheels, so the deciding factor is not wheel diameter but whether the car is intended to run the earlier numeric bias-ply tire or the radial alternative. The size molded on the current tire is the quickest first check.
After reading the existing sidewall, compare the wheel and tire setup as a complete package rather than choosing by year alone. If the car is a long-term restoration, check old photos, service records, or marque references as well, since maintaining the established construction type usually gives the most consistent result in appearance, steering feel, and ride character.
Bentley T tire listings here include several sidewall styles: narrow whitewall, whitewall with redline, wide whitewall, and blackwall. The 815-15 bias-ply products are offered as a 1.00-inch whitewall and as a whitewall-redline combination. The 205R15 radial products appear in both wide whitewall and blackwall form.
Sidewall choice affects the car’s visual tone almost as much as the size itself. A Bentley T restored with a more formal luxury presentation may suit a whitewall treatment, while a blackwall radial can give a cleaner later-period look; the right choice depends on the year, the character of the restoration, and whether you are preserving originality or a long-established personal specification.
Bentley T tires in the listed sizes are available here from BFGoodrich, Phoenix, and Avon. BFGoodrich appears in the 815-15 bias-ply size, while Phoenix and Avon appear in 205R15 radial form. That mix reflects the way Bentley T fitment spans older American-style numeric sizing and later radial sizing conventions.
Brand choice should come after you confirm the exact size and construction the car needs. Once that is settled, compare the available sidewall treatments and overall presentation, because a Bentley T often has very specific visual expectations, and the right brand-and-style combination should support both the way the car looks parked and the way it behaves on the road.
Maintenance & Longevity
A Bentley T stores best in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and long exposure to heat. Proper inflation matters even when the car is not being driven regularly, because underinflation can create flat spotting and sidewall stress over time. Clean floors and a stable indoor environment help preserve both bias-ply and radial tires.
If the Bentley T will sit for extended periods, move it periodically or support it in a way that reduces prolonged loading on one contact patch. Cars fitted with older-style bias-ply tires deserve especially careful storage because collector tires often age out long before they wear out, and preserving casing shape is part of preserving ride quality when the car returns to service.
Tires on a Bentley T should be inspected before every drive and more thoroughly several times during the year, even if mileage is very low. Look for pressure loss, cracking, sidewall distortion, tread separation signs, uneven wear, and valve condition. On a collector car, time and storage conditions can affect the tire just as much as road use.
That routine matters even more if your Bentley T alternates between long storage periods and occasional touring. A quick visual walk-around is not enough for a heavy luxury car; inspect the inner and outer sidewalls, confirm pressures when cold, and pay attention to any change in steering feel or vibration because those are often the first clues that a tire issue is developing.
A Bentley T can need new tires even when the tread still looks respectable, because age, heat cycles, storage history, and internal deterioration all matter on collector vehicles. Cracking, hardening, bulges, repeated pressure loss, or any sign of casing damage are clear replacement triggers. Low annual mileage does not protect an older tire from aging out.
Treat calendar age and condition as seriously as wear depth, particularly on a substantial car like a Bentley T. If the car has sat for years, or if there is any doubt about the history of the fitted tires, a specialist inspection is prudent before road use, and replacement is usually wiser than trying to extend service from a tire whose age or condition is already in question.
Restoration & Authenticity
Bentley T appears here with more than one period-appropriate fitment approach across its production years: 815-15 in earlier years, 205R15 in 1972, and HR70-15 in 1976. That means there is not one single answer that covers every Bentley T. The correct original-style direction depends on the exact year and the specification of the individual car.
For restoration work, treat the year as the starting point and then verify the car’s history as closely as possible. If originality matters for presentation or judging, compare the tire size and sidewall style against factory literature, early photos, or marque-club references so the final selection reflects not just what fits the wheel, but what belongs on that specific Bentley T.
Correct tire fitment can influence both the presentation and the perceived authenticity of a Bentley T, especially when judges or experienced collectors notice profile, sidewall treatment, and construction type. A car wearing a size or style that clashes with its year can look subtly wrong even if the wheel diameter is correct. On a prestige saloon, those details tend to stand out.
For owners focused on concours standards or preservation value, tire choice should support the period stance and overall character of the car. Marque clubs, archival photographs, and established restoration references are the best tie-breakers when more than one acceptable-looking option exists, because they help distinguish what is merely serviceable from what is truly era-appropriate for a Bentley T.
Bentley T tire offerings here include narrow whitewall, whitewall-redline, wide whitewall, and blackwall options depending on size. No single sidewall style applies to every year because the listed fitments span different tire constructions and visual eras. The right restoration choice therefore depends on both the size your car uses and the look you are trying to return it to.
A more formal, luxury-oriented restoration may call for a whitewall treatment, while a later radial-equipped Bentley T can suit a restrained blackwall presentation. The strongest approach is to match the sidewall style to period photos, surviving original examples, or marque guidance, since sidewall appearance can change the personality of the car even when the tire size itself is correct.
Safety & Road Use
A properly sized, properly installed tire in sound condition can be appropriate for public-road use on a Bentley T, but safety depends on more than the sidewall marking alone. Construction type, age, inflation, wheel condition, and overall vehicle condition all matter. A Bentley T is a substantial car, so the tires need to be matched to the car’s setup and kept in healthy operating condition.
For practical road use, keep the tire type consistent across the car unless a knowledgeable specialist has planned otherwise, and inspect the wheels, suspension, and steering at the same time. If the car has been sitting, or if you are unsure how old the fitted tires are, treat recommissioning seriously before regular driving rather than assuming tread depth tells the whole story.
Before driving a Bentley T, check cold tire pressures, visible sidewall condition, tread condition, valve stems, and whether all four tires match in size and construction. On a 1972 Bentley T, also confirm that the car is consistently fitted either for the listed bias-ply size or for the listed radial size rather than an accidental mixture. Wheel and spare-tire condition deserve the same attention.
That pre-drive check is especially valuable on collector cars that spend long stretches parked. A few minutes spent looking for cracking, bulges, impact damage, or pressure loss can prevent damage to the car and improve road manners, and any new vibration, pull, or steering oddity should be taken as a reason to stop and inspect rather than drive through it.
Appropriate speed for a Bentley T depends on the exact tire fitted, its age, condition, construction, and how closely the rest of the car has been maintained. An older-style bias-ply setup should generally be treated more conservatively than a healthy radial setup, especially on a heavy luxury car designed for smooth, controlled motoring rather than abrupt inputs. Age matters as much as design.
The sensible approach is to drive within the limits of the tire type and the mechanical condition of the car, building speed only after confirming stable handling and correct pressures. If the tires are older, of uncertain history, or have spent years in storage, keep speeds modest until the car has been thoroughly evaluated, because confidence in a collector Bentley starts with tire condition, not just fitment.
