The 1968 Bentley T arrived at a moment when Bentley blended traditional British luxury with a more modern, understated presentation than many earlier coachbuilt cars. Buyers and collectors value these cars for their refined road manners, stately proportions, and close ties to Rolls-Royce engineering of the period. Tire selection for the 1968 Bentley T centers on one primary fitment, the 815-15 bias-ply tire on a 15-inch rim. Within that size, the main choices focus on sidewall presentation, including a narrow whitewall or a whitewall-redline treatment in BFGoodrich's Silvertown Classic Bias Ply series. For restoration-minded ownership, the right decision comes down to preserving the car's period character while confirming wheel compatibility and overall condition before road use.
Which Tire Size Is Right for The 1968 Bentley T
The 1968 Bentley T uses one primary tire size: 815-15 in bias-ply construction on a 15-inch rim. The Bentley T Series sub-model uses that same fitment, so the question is less about choosing between sizes and more about selecting the right sidewall treatment and period-style tire presentation within the correct size.
An 815-15 is a numeric bias-ply size in which the 8.15 figure refers to the tire's nominal section width in inches and the 15 identifies the wheel diameter. Its bias-ply construction suits the period character of a 1968 Bentley T and keeps the tire choice aligned with the type of fitment associated with the car. Available options in this size include BFGoodrich Silvertown Classic Bias Ply tires with either a narrow whitewall or a whitewall-redline sidewall treatment. That makes 815-15 the size to use when the goal is proper fitment with a restoration-oriented look on the correct 15-inch wheel.
Fitment is straightforward for the covered 1968 Bentley T sub-models because the same primary tire size is used throughout. Checking the exact sub-model still matters, but tire selection remains centered on the same 815-15 bias-ply fitment.

Tire Size & Fitment
What tire size fits a 1968 Bentley T?
The 1968 Bentley T uses an 815-15 tire size. This is a bias-ply fitment and it remains the central size choice for the Bentley T covered here, including the T Series sub-model.
Using the correct size is the starting point, but condition and wheel compatibility matter just as much on a collector car. Before replacing tires, confirm that the car still has the proper 15-inch wheels, check for any past wheel changes, and choose the sidewall style that matches the look you want for touring, preservation, or restoration-oriented use.
What size rim does a 1968 Bentley T use?
The 1968 Bentley T uses a 15-inch rim with its 815-15 tire fitment. Available 815-15 products in this application are built for that 15-inch wheel diameter and are suited to rim widths in the 5.00 to 6.50 inch range.
Rim diameter is only one part of the fitment picture, especially on an older luxury car that may have seen wheel replacement over time. Measure the wheel, confirm its width, and inspect the rim for damage, corrosion, or bead-seat issues so the new tire is matched to both the intended size and the actual wheel on the car.
Does the 1968 Bentley T Series use the same tire size?
Yes. The 1968 Bentley T Series uses the same 815-15 bias-ply tire size as the model core. That makes fitment relatively straightforward compared with vehicles that split tire sizes by trim or body configuration.
Even with shared sizing, tire choice still affects how the car presents. The practical decision is whether a narrow whitewall or a whitewall-redline sidewall better suits the Bentley's appearance, while also confirming that the existing wheels remain 15-inch rims within the proper width range for the 815-15 size.
Choosing the Right Tire
What should I consider when choosing an 815-15 tire for a 1968 Bentley T?
Start with the basics: the correct size is 815-15, the construction is bias-ply, and the wheel should be a 15-inch rim within the proper width range. On this Bentley, the main visible difference among available choices is sidewall treatment rather than a change in size or construction.
Selection usually comes down to the car's intended presentation and use. A preservation-minded owner may focus on a traditional narrow whitewall look, while another may prefer the added visual character of a whitewall-redline combination. It also helps to compare load figures, wheel condition, and how closely the current setup matches the car's original-style appearance.
What sidewall styles are available for 1968 Bentley T tires?
Two sidewall styles are available in 815-15 for the 1968 Bentley T: Narrow Whitewall and Whitewall-Redline. Both are offered in BFGoodrich's Silvertown Classic Bias Ply series, so the visual treatment is the main difference rather than a change in fitment category.
That choice matters because sidewall appearance strongly shapes how a large British luxury car sits and reads visually. A narrow whitewall gives a restrained, formal presentation, while a whitewall-redline treatment adds more contrast. Either way, keep the focus on the correct 815-15 size and make sure the wheels and overall stance still suit the tire's proportions.
What brands offer tires for the 1968 Bentley T?
BFGoodrich is the available brand for the 1968 Bentley T in the 815-15 size. The applicable products fall within the Silvertown Classic Bias Ply series and keep the Bentley's tire selection centered on period-style bias-ply construction.
With one brand in the mix, comparison shifts away from brand preference and toward specification and appearance. The more useful questions are which sidewall style suits the car, whether the tire matches the existing 15-inch wheel setup, and whether the car's intended use calls for a more formal whitewall look or a more distinctive sidewall presentation.
Restoration & Appearance
Which tire should I choose for a period-style 1968 Bentley T?
An 815-15 bias-ply tire is the period-style starting point for a 1968 Bentley T. That size and construction keep the car aligned with the type of tire fitment associated with its late-1960s luxury character, while available choices let you refine the look through sidewall styling.
The decision often comes down to how formal or expressive the finished car should appear. A narrow whitewall generally delivers a more restrained presentation, while a whitewall-redline treatment stands out more. When exact originality matters, compare the tire choice against marque references, restoration records, and the car's own historical details before settling on appearance alone.
Does correct tire fitment matter for a 1968 Bentley T restoration?
Yes, correct tire fitment matters because tire size and construction have a strong effect on stance, visual balance, and overall authenticity of presentation. On a 1968 Bentley T, staying with the 815-15 bias-ply format helps preserve the kind of look expected from a substantial British luxury car of the period.
Fitment also affects how the restoration functions on the road. A tire that matches the proper wheel diameter and width helps avoid unnecessary complications during mounting and use, while the right sidewall style supports the car's finished appearance. Restorers should also inspect wheel condition carefully, since old rims can undermine even a well-chosen new tire.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1968 Bentley T?
Yes. Even though the standard fitment is 815-15 on a 15-inch rim, modifications can change what actually works on the car. Aftermarket wheels, altered ride height, brake changes, or body repairs can all affect clearance and wheel compatibility.
A Bentley T that still appears stock may still have a changed wheel setup, so it is worth measuring before ordering tires. Confirm wheel diameter and width, inspect inner and outer clearance, and look for signs of rubbing at the fender, suspension, or steering components. Those checks are especially important on a collector car that has passed through several owners.
What should I inspect before driving a 1968 Bentley T on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and overall tire seating on the rim. It also makes sense to check suspension components, steering play, and brake condition so the new 815-15 tires are not being asked to compensate for unrelated mechanical wear.
Collector cars often spend long periods parked, which means surrounding systems deserve attention along with the tires themselves. Look for uneven ride height, fluid leaks near brake components, and any old alignment issues that could disturb tread wear. Once mounted, maintain proper inflation, recheck air pressure after initial use, and keep an eye out for vibration or pull on the first drives.
How should 815-15 tires on a collector 1968 Bentley T be maintained?
Maintain 815-15 tires on a collector 1968 Bentley T by keeping inflation consistent, inspecting the sidewalls and tread regularly, and watching for cracking, cuts, bulges, or slow air loss. Low-use collector cars can age tires quietly, even when tread still looks serviceable.
Storage conditions matter almost as much as mileage. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment when possible, and move or drive it periodically to avoid long static loading in one position. Regular visual checks, pressure checks, and attention to the wheels themselves help preserve both safety and the car's road-ready condition.
