The 1970 Bentley T belongs to an era when Bentley offered understated luxury with substantial road presence, sharing much of its engineering character with its Rolls-Royce counterpart while keeping a distinct identity. Buyers drawn to these cars today are often balancing preservation, presentation, and confident touring use. For the 1970 Bentley T, the primary tire fitment is 815-15 in bias-ply construction on a 15-inch rim. Available choices stay close to that traditional setup, with BFGoodrich Silvertown Classic Bias Ply options in narrow whitewall and whitewall-redline styling. The real decision is less about size and more about selecting the sidewall treatment that best suits the car’s character and restoration direction.
Which Tire Size Is Right for The 1970 Bentley T
The 1970 Bentley T uses one primary tire size: 815-15, a bias-ply fitment for a 15-inch rim. That same size carries across the Bentley T Series covered here, so the main choice is not between multiple fitments, but between period-style tire presentation options within the correct size and construction.
An 815-15 uses the older numeric bias-ply sizing system, where 8.15 refers to the tire’s nominal section width in inches and 15 identifies the wheel diameter. On a 1970 Bentley T, this is a traditional bias-ply fitment that supports the car’s original-era stance and overall visual character. Available options include BFGoodrich Silvertown Classic Bias Ply tires with either a narrow whitewall or a whitewall-redline sidewall treatment. This size makes the most sense for owners who want to keep the Bentley on its primary vintage construction while choosing the appearance that best matches the car.
Fitment is straightforward across the covered 1970 Bentley T sub-models. The key point is confirming that the car is a Bentley T Series, then selecting the correct 815-15 bias-ply tire and the sidewall style that suits the vehicle’s presentation.

Available 815-15 choices for the 1970 Bentley T center on BFGoodrich Silvertown Classic Bias Ply tires, with the main distinction being sidewall appearance. Buyers can compare a narrow whitewall against a whitewall-redline version while staying within the same traditional size and construction.
Common questions for the 1970 Bentley T usually center on the 815-15 tire size, 15-inch rim fitment, bias-ply construction, sidewall appearance, and what to inspect before putting a collector Bentley back on the road.
Tire Size & Fitment
What tire size fits a 1970 Bentley T?
The 1970 Bentley T uses an 815-15 tire. This is a numeric bias-ply size fitted to a 15-inch rim, and it is the primary fitment for the Bentley T covered here, including the T Series sub-model.
That makes the first step fairly simple: confirm the car still has the correct 15-inch wheels and then choose among the available 815-15 bias-ply options. If the car has been modified with different wheels or suspension changes over the years, wheel width, clearance, and overall tire presentation should be checked before selecting a replacement.
What size rim does a 1970 Bentley T use?
The 1970 Bentley T uses a 15-inch rim with its 815-15 tire size. Available 815-15 products in this fitment are built for 15-inch wheels and carry a rim-width range of 5.00 to 6.50 inches.
Rim diameter is the first item to verify on a collector car, especially if the wheels may have been changed at some point. Wheel width matters too, because staying within the tire’s approved rim-width range helps preserve proper tire shape, supports predictable fitment, and reduces the chance of avoidable clearance or mounting issues.
Does the 1970 Bentley T Series use the same tire size?
Yes. The 1970 Bentley T Series uses the same 815-15 bias-ply tire size as the Bentley T fitment covered here. There is no separate primary tire size within this sub-model grouping.
That consistency means the buying decision is mostly about tire style rather than alternate fitments. Once the correct wheel diameter and wheel width are confirmed, the focus can shift to appearance details such as narrow whitewall versus whitewall-redline, along with the broader goal of preserving a traditional period-style look on the car.
Choosing the Right Tire
What should I consider when choosing a 815-15 tire for a 1970 Bentley T?
Start with the correct size and construction: 815-15 in bias-ply form on a 15-inch rim. From there, the important differences are wheel-width compatibility, sidewall appearance, load capacity, and how closely the tire matches the look and use you have in mind for the car.
For this Bentley, available 815-15 options share the same BFGoodrich Silvertown Classic Bias Ply series, 1610@32 psi maximum load capacity, and 5.00 to 6.50 inch rim-width range. That makes sidewall treatment a major point of comparison, especially if the goal is a more formal touring presentation or a slightly more distinctive vintage look.
What sidewall styles are available for 1970 Bentley T tires?
The 1970 Bentley T has 815-15 tire options with two sidewall styles: a narrow whitewall and a whitewall-redline treatment. Both are offered in bias-ply construction within the same Silvertown Classic Bias Ply series.
Sidewall choice has a strong effect on the car’s visual tone even when the size and construction stay the same. A narrow whitewall tends to suit a restrained luxury presentation, while the whitewall-redline version gives a more distinctive period-style accent. The right choice usually depends on the Bentley’s restoration direction, wheel appearance, and overall trim presentation.
How do I choose between the available 815-15 tires for a 1970 Bentley T?
The available 815-15 choices for a 1970 Bentley T are closely matched in core specifications, so the decision comes down mainly to appearance and compatibility. Both options are BFGoodrich bias-ply tires in the Silvertown Classic Bias Ply line with the same load rating, weight, and rim-width range.
That means the most practical comparison is whether the sidewall styling complements the car the way you want. Check that the wheel falls within the approved 5.00 to 6.50 inch width range, then choose the tire that best fits the Bentley’s intended character, whether that leans toward subtle formal elegance or a more pronounced vintage accent.
Restoration & Appearance
Which tire should I choose for a period-style 1970 Bentley T?
An 815-15 bias-ply tire is the period-style starting point for a 1970 Bentley T. Keeping the original-era size format and bias-ply construction helps preserve the visual proportions and traditional tire presentation associated with a luxury car of this period.
From there, the finer point is sidewall appearance. A narrow whitewall usually gives a more restrained look, while a whitewall-redline option adds a stronger visual statement. If exact originality matters for a restoration, it is worth checking marque references, period photography, or build-related documentation before settling on a specific sidewall treatment.
How does tire construction affect the appearance of a restored 1970 Bentley T?
Tire construction changes more than ride feel on a restored 1970 Bentley T; it also changes the car’s visual impression. A bias-ply tire such as the 815-15 maintains a more traditional vintage look that suits the car’s era and formal proportions.
On a restoration-minded Bentley, the tire sidewall shape and overall presentation are part of the finished result, not just a mechanical detail. Keeping the proper size and a traditional construction can help the car look more settled and period-appropriate. That is especially important on a large luxury car where wheel and tire appearance is easy to notice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1970 Bentley T?
Yes. A 1970 Bentley T may have originally used 815-15 bias-ply tires on 15-inch wheels, but changes to wheel width, wheel offset, suspension height, or body clearance can affect what works on the car today. Even a correct nominal size should be checked against the current setup.
Collector cars are often altered over decades of ownership, sometimes in ways that are not obvious at first glance. If the Bentley has aftermarket wheels, replacement springs, or any chassis changes, inspect wheel diameter, wheel width, steering clearance, and fender space before mounting new tires. That extra step helps avoid surprises once the car is back on the road.
What should I inspect before driving a 1970 Bentley T on new tires?
Before putting a 1970 Bentley T into regular road use on new tires, inspect the wheels, valve stems, and overall condition of the suspension and steering system. It also helps to confirm that the tire size, rim diameter, and wheel width all match the intended fitment.
A collector Bentley can sit for long periods, so roadworthiness involves more than fresh rubber. Check for looseness, fluid leaks, uneven wear patterns from previous alignment issues, and any signs of rubbing at full steering lock. Once the tires are installed, monitor air pressure and recheck the car after the first few drives for clearance and seating concerns.
How should 815-15 tires on a collector 1970 Bentley T be maintained?
Maintain 815-15 tires on a collector 1970 Bentley T by checking air pressure regularly, inspecting the sidewalls and tread for cracking or damage, and watching for slow air loss. Because this is a vintage-style bias-ply fitment, routine condition checks are especially important when the car is driven infrequently.
Storage conditions matter just as much as mileage on a collector car. Keep the Bentley away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or compressors. During driving season, examine the tires before longer trips and look for bulges, cuts, irregular wear, or any change in behavior that could point to a developing problem.
