The 1976 Bentley T came from an era when hand-finished luxury still defined the driving experience, pairing substantial road presence with the quiet, composed character expected of a Bentley sedan. Buyers looking after one today are usually balancing originality, ride quality, and confident road manners rather than chasing aggressive fitment changes. This car uses an HR70-15 radial tire on a 15-inch rim, so the main decision is less about multiple factory sizes and more about selecting the right tire within that fitment. For a restoration-minded car, the focus shifts to correct size, proper radial construction, and a tire that suits both the Bentley’s appearance and intended use.
Which Tire Size Is Right for The 1976 Bentley T
The 1976 Bentley T uses one primary tire size: HR70-15. That fitment is a radial on a 15-inch rim, and it carries across the covered T Series sub-model, so the real choice is selecting the right tire within that size while confirming the actual wheel setup on the car has not been changed over time.
HR70-15 is a vintage alphanumeric radial size in which the letter designation identifies the tire’s size class, the R indicates radial construction, the 70 refers to the profile family, and 15 is the rim diameter in inches. On a 1976 Bentley T, that matters because radial construction is the primary fitment rather than a later conversion from bias-ply. This size suits buyers who want to stay with the established fitment for the car and then narrow the choice by tire design, ride character, and restoration presentation. Wheel condition, true rim size, and any past modifications should still be checked before final selection.
Fitment is straightforward across the covered 1976 Bentley T sub-models. The T Series uses the same primary tire size, so the main job is confirming that the car still carries its correct 15-inch wheel setup and has not been altered with aftermarket wheels.

Frequently Asked Questions
Owners of a 1976 Bentley T usually want clear answers on HR70-15 sizing, 15-inch rim fitment, restoration-minded tire selection, and the checks worth making before putting a heavy luxury car back into regular road use.
Tire Size & Fitment
What tire size fits a 1976 Bentley T?
The 1976 Bentley T uses an HR70-15 tire size. This is a radial fitment on a 15-inch rim, and it is the primary size associated with the model.
That makes size selection fairly straightforward, but it is still worth confirming the actual wheels on the car before replacing tires. Many collector cars have seen wheel changes over the years, and even when the size marked on the old tire is correct, wheel condition, rim width, and clearance around suspension and bodywork should be checked before mounting a new set.
What size rim does a 1976 Bentley T use?
The 1976 Bentley T uses a 15-inch rim with its HR70-15 tire fitment. The tire’s final number, 15, matches the wheel diameter in inches.
Rim diameter is the first thing to confirm before ordering replacement tires, especially on a car that may have changed hands several times. Measuring the wheel or verifying the stamping on the rim helps prevent costly mistakes, and it also gives a better starting point for checking whether the car is still on its intended wheel setup rather than an aftermarket substitute.
Does the 1976 Bentley T Series use the same tire size?
Yes. The 1976 Bentley T Series uses the same HR70-15 radial tire size. Fitment remains consistent across the covered sub-model rather than splitting into different primary sizes.
That consistency simplifies replacement planning because the focus stays on selecting the right tire within the correct size, not sorting through multiple factory fitments. Even so, an individual car should still be checked for wheel swaps, suspension changes, or unusual clearance issues, since those real-world conditions matter more than model naming once the tires are ready to be mounted.
Choosing the Right Tire
What should I consider when choosing an HR70-15 tire for a 1976 Bentley T?
Start with the correct size and construction: HR70-15 radial on a 15-inch rim. For a 1976 Bentley T, the next considerations are the car’s intended use, the condition of the wheels, and whether the goal is preservation, regular touring, or a restoration-oriented appearance.
A heavy luxury car benefits from careful attention to wheel condition, tire age, and overall fitment rather than size alone. Looking at load-related specifications, verifying the tire matches the actual wheel setup, and checking for adequate clearance at full steering lock can help avoid problems that might not show up until the car is back on the road.
How do I choose between the available HR70-15 tires for a 1976 Bentley T?
Choosing between HR70-15 tires comes down to matching the tire to the way the Bentley T will be used and presented. Even when size and radial construction stay the same, tires can differ in design details that affect the car’s visual character and the kind of ownership experience the buyer wants.
A car headed for touring use may be judged differently than one being finished for a preservation-minded display setting. It helps to compare the tire’s overall presentation, construction type, wheel compatibility, and any available load-related details, then weigh those factors against the condition of the suspension, steering components, and the originality of the wheel setup.
What rim-fitment details should I compare when choosing 1976 Bentley T tires?
The most important rim-fitment detail is wheel diameter, which is 15 inches for the 1976 Bentley T’s HR70-15 tire size. After that, the condition and true specification of the wheel matter because an older car may no longer be running the wheel setup it originally used.
Checking the wheel itself is especially important on a collector Bentley because bent rims, corrosion, or prior repairs can affect how a new tire seats and performs. A buyer should also look at wheel width, tire-to-body clearance, and any signs that the suspension height or geometry has been altered since those changes can influence tire selection even when the nominal size remains correct.
Restoration & Appearance
Which tire should I choose for a period-style 1976 Bentley T?
A period-style starting point for a 1976 Bentley T is the correct HR70-15 radial size on a 15-inch rim. Staying with the proper size and construction preserves the visual proportions the car was built around and keeps the selection aligned with the Bentley’s formal luxury character.
For a restoration-minded car, appearance should be considered alongside road use and wheel condition rather than treated as a separate issue. Buyers who want a more historically faithful presentation should compare available tire designs carefully and, when exact originality matters, consult marque references or restoration documentation specific to the individual car before making a final choice.
Does correct tire fitment matter for a 1976 Bentley T restoration?
Yes, correct tire fitment matters a great deal on a 1976 Bentley T restoration. The right HR70-15 sizing helps preserve the car’s stance, wheel-to-body proportion, and overall visual balance, all of which are especially noticeable on a large, formal luxury sedan.
Fitment also affects more than appearance. An incorrect diameter, mismatched wheel, or poorly chosen substitute can change how the car sits and may create clearance or drivability concerns that work against an otherwise careful restoration. Getting the tire size right early in the process helps keep suspension, alignment, and final presentation decisions moving in the right direction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1976 Bentley T?
Yes. Modifications can affect tire fitment on a 1976 Bentley T even when the intended replacement size is still HR70-15. Aftermarket wheels, suspension work, altered ride height, or body repairs can all change the space available for the tire.
A Bentley of this age may also have accumulated changes that are not obvious until the car is inspected closely. Looking at steering clearance, wheel width, and how the tire sits within the wheel opening helps catch issues before installation, especially if the car has been restored, lowered, or updated at any point in its life.
What should I inspect before driving a 1976 Bentley T on new tires?
Before driving a 1976 Bentley T on new tires, inspect the wheels, valve stems, and the general condition of the suspension and steering components. The new tires should be checked for proper inflation, secure mounting, and any signs of interference once the car is on the ground.
A short, careful road test is a smart next step because older luxury cars can reveal vibration, pull, or clearance problems only under motion. It also helps to recheck air pressure after the first drive and look again for rubbing marks, uneven stance, or looseness in related components before taking the car on a longer trip.
How should HR70-15 tires on a collector 1976 Bentley T be maintained?
HR70-15 tires on a collector 1976 Bentley T should be maintained with regular pressure checks, periodic visual inspection, and attention to age-related condition even if the car is driven only sparingly. Tread depth alone is not enough on a low-mileage collector car.
Sidewall cracking, flat spotting from long storage, bulges, cuts, and slow air loss deserve close attention on a heavy sedan that may spend long periods parked. Good storage habits also matter, including keeping the car away from prolonged sunlight, moisture, and ozone sources, then inspecting the tires again before returning the Bentley to regular road use.
