1958 Bentley S-Type Tires

The 1958 Bentley S-Type uses an 820-15 tire size in bias-ply construction. This is a vintage numeric size fitted to a 15-inch rim and serves as the primary fitment for the covered model.

That means the first step is staying in the 820-15 size family before comparing brands, sidewall styles, or construction alternatives. If the car has replacement wheels, previous tire substitutions, or suspension changes, it is worth confirming the actual wheel dimensions and available clearance before selecting a new tire.

The 1958 Bentley S-Type uses a 15-inch rim with its 820-15 tire fitment. Product offerings in this size commonly pair with rim widths in the 6.00 to 6.50 inch range, while some specialty versions use wider wheel ranges.

Rim diameter is the non-negotiable starting point, because a 15-inch tire must match a 15-inch wheel. Wheel width matters too, especially if the car has aftermarket wheels or if a radial-equivalent size is being considered, since construction changes can make wheel compatibility and clearance checks more important.

Yes. The 1958 Bentley S-Type Base uses the same 820-15 bias-ply tire size as the covered S-Type fitment. That keeps the basic size question simple and consistent across the page.

With the size already established, the real decision becomes how you want the car to look and drive. A buyer can focus on blackwall versus whitewall styling, compare available tire series, or look at radial-equivalent options while still verifying wheel width and overall fit on the specific car.

For the 1958 Bentley S-Type, 820-15 is the primary bias-ply tire fitment. In this application, the size is presented in a vintage numeric bias-ply format rather than as a modern radial size.

Keeping bias-ply construction usually makes the most sense when maintaining a traditional period-style look and feel is the priority. Moving away from that construction changes the decision from simple replacement to comparison, so wheel width, overall size, and clearance should all be reviewed before choosing a radial alternative.

Radial equivalents for 820-15 include 235R15 as an 80-series metric radial, P235/75R15 as a 75-series P-metric radial, P255/70R15 as a 70-series P-metric radial, and 820R15 as a bias-look radial. Each one stays in the 15-inch rim family while using a different radial sizing approach.

Those options should be treated as alternatives rather than automatic replacements. The recommended rim-width range for these equivalents is 6 to 8 inches, and the specific car should still be checked for wheel compatibility, fender clearance, and any differences created by prior wheel, suspension, or tire changes.

Yes, an 820R15 bias-look radial is available as a radial equivalent for the 1958 Bentley S-Type’s 820-15 size. It is intended for buyers who want a radial option while retaining a more traditional visual presentation than a modern metric tire may provide.

That can make it appealing on a formal collector car where appearance matters as much as construction choice. Even so, the change still deserves the same checks as any other radial conversion, including wheel width, overall dimensions, steering clearance, and the condition of the suspension and steering components.

Start with the correct 820-15 size and a 15-inch wheel, then narrow the choice by construction, sidewall style, and intended use. The available range includes traditional bias-ply touring-style tires along with specialty performance-oriented versions that differ in character and wheel-width requirements.

A restoration-minded Bentley owner may prioritize a period-style profile and whitewall treatment, while a driver focused on road use may also compare radial-equivalent alternatives. Rim width, load capacity figures where stated, and the overall condition of the car’s wheel and suspension setup all deserve attention before making the final selection.

The 1958 Bentley S-Type has 820-15 tire choices in blackwall, narrow whitewall, and wide whitewall styles. That gives the car a broad appearance range, from a restrained touring look to a more formal period-style whitewall presentation.

Sidewall choice changes the visual character of the car more than the size itself, so it is worth matching the tire to the way the Bentley will be presented. Buyers aiming for restoration-oriented appearance often compare whitewall widths carefully, while drivers who prefer a simpler look may stay with a blackwall bias-ply option.

Brands available in 820-15 for the 1958 Bentley S-Type include BFGoodrich, Firestone, US Royal, Universal Vintage Tire, and Avon. Those brands appear across several bias-ply series and sidewall treatments, giving the Bentley owner more than one path within the correct primary size.

Brand alone should not decide the tire. It is smarter to compare the specific series, sidewall treatment, rim-width suitability, and whether the tire is a traditional road-going bias-ply design or a more specialized offering. That approach keeps the choice centered on fitment and presentation instead of name recognition.

A period-style 1958 Bentley S-Type usually starts with the 820-15 bias-ply size, since that preserves the car’s original-era sizing format and traditional visual proportions. Within that size, blackwall, narrow whitewall, and wide whitewall versions all create distinctly different but still era-appropriate presentations.

The right choice depends on how formally the car is being restored and how it will be used once finished. Buyers pursuing exact historical authenticity should compare surviving photos, marque-club guidance, and vehicle-specific documentation, while those focused on presentation can choose the sidewall treatment that best suits the car’s character.

Tire construction can noticeably influence how a restored 1958 Bentley S-Type looks. A bias-ply 820-15 keeps the car in its original-style size format and generally supports a more traditional vintage presentation than a modern metric radial alternative.

That difference matters most on a car with formal lines and a strong period identity. A bias-look radial can soften the visual change for owners who want radial construction, but appearance should still be judged alongside wheel width and overall fit so the restored car keeps balanced proportions and proper road clearance.

Yes. Modifications can affect tire fitment on a 1958 Bentley S-Type even when the tire size remains 820-15 or a recognized radial equivalent. Aftermarket wheels, altered wheel width, changed offset, suspension work, or body modifications can all influence how much clearance the tire has in actual use.

A Bentley that has been lowered, fitted with replacement wheels, or converted to another tire construction should be checked at full steering lock and through suspension travel. Looking at real wheel dimensions and physical clearance on the car is more useful than assuming that the nominal size alone settles the fitment question.

Before driving a 1958 Bentley S-Type on new tires, inspect the wheels for correct diameter and sound condition, confirm proper mounting, and check that the tires clear the fenders and steering components. It also helps to verify inflation, valve condition, and that the spare and road tires are in matching serviceable condition.

Collector cars often spend long periods parked, so tire age and general chassis condition matter as much as fresh tread. A short initial drive followed by another check for air loss, rubbing marks, and unusual handling can reveal issues early, especially if the car has not been on the road regularly.

820-15 tires on a collector 1958 Bentley S-Type should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long exposure to heat, sunlight, and ozone sources. Cars that sit for extended periods deserve extra attention because age-related deterioration can develop even with limited mileage.

Routine maintenance is especially important on a heavy luxury car where stability and ride depend on sound tires and sound wheels. Periodic checks of alignment, suspension wear, and air retention help preserve the tire investment, while occasional repositioning during storage can reduce flat spotting on low-use collector vehicles.
