The 1977 Bentley T2 Series represents the later development of Bentley’s understated full-size luxury saloon from the 1970s, a car valued for its formal presence, quiet road manners, and hand-finished character. Buyers looking after one today are usually balancing proper appearance with dependable road use rather than chasing an aggressive tire setup. This Bentley uses an HR70-15 radial tire on a 15-inch rim, so the fitment conversation is centered on one primary size rather than multiple factory-type configurations. The key choices come down to selecting the right tire within that vintage alphanumeric radial size and confirming that the wheel and overall setup remain true to the car.
Which Tire Size Is Right for The 1977 Bentley T2 Series
The 1977 Bentley T2 Series uses one primary tire size: HR70-15, and it is a radial fitment for a 15-inch rim. The same size applies to the covered Base sub-model, so the main decision is not sorting between multiple factory-type sizes, but choosing the right HR70-15 tire for the car’s appearance, driving use, and wheel compatibility.
HR70-15 is a vintage alphanumeric radial size in which the letter-based sizing class works with the 70-series profile and 15-inch rim diameter to describe the tire’s fitment format. Because this is already a radial construction, it suits buyers who want to retain the T2 Series’ primary tire type rather than convert from bias-ply. For this Bentley, the real comparison is usually between available tires within the HR70-15 category, with attention paid to overall presentation, wheel match, and how closely the tire supports the car’s formal late-1970s luxury character. It is a size that rewards careful selection rather than experimentation.
Tire fitment is straightforward across the covered 1977 Bentley T2 Series sub-models. The Base model uses the same primary size, so the buying focus stays on choosing the right HR70-15 tire rather than sorting through multiple sub-model-specific fitments.

Frequently Asked Questions
Common questions for the 1977 Bentley T2 Series usually center on the HR70-15 size, 15-inch rim fitment, period-appropriate tire selection, and what to inspect before putting a large collector-era luxury sedan back on the road.
Tire Size & Fitment
What tire size fits a 1977 Bentley T2 Series?
The 1977 Bentley T2 Series uses HR70-15 tires. This is the primary fitment for the model and it is a radial tire size, which makes the size choice itself fairly straightforward compared with vehicles that use different sizes across multiple trims or wheel packages.
The practical next step is confirming that the car still has the correct 15-inch wheels and that no previous owner changed the wheel or suspension setup. On a collector luxury car, appearance and road behavior matter, so staying with the proper size format helps preserve both the stance of the car and the intended fit around the wheel opening.
What size rim does a 1977 Bentley T2 Series use?
The 1977 Bentley T2 Series uses a 15-inch rim with its HR70-15 tire size. That means the tire is intended for a wheel with a 15-inch bead-seat diameter, which is the critical measurement to verify before selecting any replacement tire.
Wheel diameter should be confirmed directly on the car, especially if it has been in long-term ownership or has passed through restoration work. A tire with the correct size family still needs the proper wheel to match, and checking the actual wheel before purchase helps avoid problems with mounting, appearance, or overall fit on the Bentley.
Does the 1977 Bentley T2 Series Base use the same tire size?
Yes. The 1977 Bentley T2 Series Base uses the same HR70-15 radial tire size. That keeps fitment simple within the covered sub-model range, since there is no need to sort between separate primary tire sizes for different versions of the car.
Even with shared fitment, it is still worth checking the actual wheels on the individual car. Older Bentleys are sometimes fitted with replacement wheels during restoration or maintenance, and any change in wheel dimensions can affect how the correct tire size mounts and how it sits within the fender and suspension space.
Choosing the Right Tire
What should I consider when choosing an HR70-15 tire for a 1977 Bentley T2 Series?
Start with the correct size and construction: HR70-15 radial on a 15-inch rim. Once that is established, the important considerations become how the tire suits the Bentley’s formal luxury character, whether the wheel dimensions remain appropriate, and whether the tire’s overall presentation matches the level of restoration or preservation the owner wants.
It also helps to think about how the car is used. A Bentley kept for occasional fair-weather touring may call for a different selection emphasis than one driven more regularly. Looking closely at wheel condition, ride expectations, and the visual relationship between tire and body helps narrow the choice without straying from the correct size.
How do I choose between the available HR70-15 tires for a 1977 Bentley T2 Series?
Choosing between HR70-15 tires for a 1977 Bentley T2 Series comes down to selecting the tire that best matches the car’s purpose and presentation while staying within the correct size. Since the fitment itself is fixed, the comparison is less about finding a usable size and more about the character of the tire within that size category.
Focus on factors such as wheel compatibility, the look you want on the car, and whether the Bentley is maintained as a restoration-oriented sedan or a regularly driven collector vehicle. On a large, formal car like the T2 Series, small differences in tire presentation can noticeably affect the overall visual balance even when the size remains correct.
What rim-fitment details should I compare when choosing 1977 Bentley T2 Series tires?
The most important rim-fitment detail is the 15-inch wheel diameter required by the HR70-15 tire size. Beyond that, the actual wheel on the car should be checked for condition, proper dimensions, and any signs that it has been replaced with something outside the original style of fitment.
That inspection matters because an older luxury car may have seen wheel service, refinishing, or replacement over the years. Confirming that the wheel remains suitable for the tire helps support proper mounting and appearance, and it reduces the chance of selecting a tire that looks out of place or creates clearance concerns at full steering lock.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Bentley T2 Series?
A period-style approach starts with the correct HR70-15 radial size, since that preserves the original fitment format used on the 1977 Bentley T2 Series. Keeping the right size family is especially important on a car with restrained luxury styling, where tire proportions play a visible role in the overall presentation.
Beyond size, the best choice depends on how strictly the car is being restored and how it will be driven. Some owners want a restoration-oriented look, while others prioritize regular road use. If exact originality matters, it is worth checking marque-specific references and historical documentation before deciding on the final tire appearance.
Does correct tire fitment matter for a 1977 Bentley T2 Series restoration?
Yes, correct tire fitment matters on a 1977 Bentley T2 Series restoration because the tire has a strong effect on both appearance and stance. Using the proper HR70-15 radial size helps the car maintain the visual proportion expected of a late-1970s Bentley saloon rather than taking on an altered or overly modern look.
Fitment also affects how naturally the tire sits on the wheel and within the fender opening. Even when a car is not being restored to a judged standard, staying close to the correct size format supports a more convincing period presentation. It is a detail that influences the whole car more than many owners expect.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Bentley T2 Series?
Yes. Modifications can affect tire fitment on a 1977 Bentley T2 Series even when the intended tire size remains HR70-15. Changes such as aftermarket wheels, altered suspension height, nonstandard springs, or previous body work can all influence how a replacement tire sits and clears the surrounding components.
A large collector sedan should be checked carefully before assuming that the original-style size will behave the same on every example. Verifying wheel diameter, wheel width, steering clearance, and fender space helps prevent surprises. It is especially wise on cars that have been restored, customized, or maintained over several decades by different owners.
What should I inspect before driving a 1977 Bentley T2 Series on new tires?
Before driving a 1977 Bentley T2 Series on new tires, inspect the wheels for damage or corrosion, confirm proper inflation, and make sure the tires seat correctly and clear the car through the steering range. It is also smart to look over suspension and steering components on a car of this age.
A freshly mounted tire cannot compensate for worn bushings, loose steering parts, or neglected alignment. Older collector vehicles often spend long periods parked, so checking for fluid leaks, brake condition, and any rubbing points during a short initial drive is just as important as the tire installation itself before returning the Bentley to regular road use.
How should HR70-15 tires on a collector 1977 Bentley T2 Series be maintained?
HR70-15 tires on a collector 1977 Bentley T2 Series should be maintained with regular pressure checks, routine visual inspection, and careful storage habits when the car is not in use. Sidewall cracking, tread irregularities, bulges, cuts, and slow air loss all deserve attention, especially on a low-mileage car.
Collector vehicles often age their tires by time and storage conditions more than by mileage. Keeping the Bentley away from prolonged sunlight, moisture, and ozone sources helps preserve tire condition, and periodic movement can reduce flat-spotting during storage. A close inspection before each longer outing is a good habit on a car that may sit between drives.
