1963 Bentley S2 Tires

The 1963 Bentley S2 uses an 820-15 tire size. This is a numeric bias-ply fitment mounted on a 15-inch rim, and it is the primary size associated with the Bentley S2 covered here, including the Base sub-model.

That means the first step is not choosing among multiple factory-type sizes, but selecting the right 820-15 tire for the car’s intended use and appearance. Buyers typically compare blackwall versus whitewall styling, tire series, and whether to remain with bias-ply construction or consider one of the available radial-equivalent alternatives after confirming wheel width and clearance.

The 1963 Bentley S2 uses a 15-inch rim with its primary 820-15 tire size. Product fitments in this size commonly pair with rim widths in the 6.00 to 6.50 inch range, while some alternative or specialty tires show broader width compatibility.

Rim diameter should always be confirmed before ordering because a 15-inch tire only mounts correctly on a 15-inch wheel. It is also worth checking actual wheel width on the car, especially if the Bentley has seen wheel changes over the years, since sidewall profile, bead seating, and overall fit can all be affected by width differences.

Yes. The 1963 Bentley S2 Base uses the same 820-15 bias-ply tire size as the core fitment for this model. There is no alternate primary tire size shown for the Base sub-model in this application.

That keeps the decision centered on tire type and presentation rather than sub-model differences. A Bentley owner can focus on choosing between blackwall, narrow whitewall, and wide whitewall styles, comparing brands and series, and deciding whether the goal is a traditional bias-ply look or a carefully checked radial-equivalent setup.

For the 1963 Bentley S2, 820-15 is a bias-ply tire size. The primary fitment is not a radial, which is why the available radial options are treated separately as equivalents rather than as the original construction style for this car.

Staying with bias-ply construction preserves the vintage sizing format and the traditional look most owners expect on a large early-1960s Bentley. Anyone thinking about a radial alternative should compare the wheel setup carefully, because construction changes can affect how the tire presents on the rim and how much space it uses within the fender and suspension area.

Radial equivalents for 820-15 include 235R15, P235/75R15, P255/70R15, and 820R15. Those options cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial intended to retain a more traditional visual character.

These alternatives give a Bentley S2 owner several ways to approach a radial conversion without assuming every option suits every wheel or chassis setup the same way. A recommended rim-width range of 6 to 8 inches is associated with the equivalent group, and the final choice should still be checked against the actual wheel width, tire dimensions, and available clearance on the car.

Yes, 820R15 is a bias-look radial equivalent for the 1963 Bentley S2’s original 820-15 size. It gives the car a radial-construction alternative while aiming to keep a more traditional tire presentation than a fully modern-looking metric radial.

That makes it appealing for owners who want to preserve a classic visual impression without staying strictly with bias-ply construction. Even so, it should be treated as an equivalent, not an automatic replacement, so wheel width, mounting compatibility, and body or suspension clearance deserve the same careful review as any other radial conversion on a vintage Bentley.

Start with the correct 820-15 size and 15-inch rim fitment, then narrow the choice by construction, sidewall style, and intended use. Most options are traditional bias-ply tires, but the assortment also includes specialty products and radial-equivalent paths that suit different priorities.

A restoration-oriented Bentley may call for a classic blackwall or whitewall presentation, while a road-driven car might push the decision toward a carefully evaluated radial equivalent instead. It also helps to compare rim-width compatibility, maximum load figures such as 1920@32 psi where stated, and the visual effect each tire series creates on a large formal saloon.

The 1963 Bentley S2 has 820-15 tire options in blackwall, narrow whitewall, and wide whitewall styles. That range allows the same basic fitment to look noticeably different, from restrained and understated to more formal and visually prominent.

Sidewall choice matters on a car like the S2 because the tire contributes heavily to the vehicle’s overall stance and period impression. A blackwall can create a more subdued appearance, while narrow and wide whitewalls offer progressively stronger vintage character. The right choice depends on how the Bentley is being presented, not just on size and construction alone.

Tires for the 1963 Bentley S2 are available from BFGoodrich, Firestone, US Royal, Universal Vintage Tire, and Avon in the 820-15 fitment. Those brands appear across several classic-style bias-ply series, with differences in sidewall treatment and certain specification details.

Brand choice is best treated as part of the overall selection process rather than as a ranking exercise. A Bentley owner should compare how each offering aligns with the car’s intended look, whether the tire is a standard classic bias-ply or a specialty design, and whether the rim-width and load specifications suit the actual wheel and road-use plans.

An 820-15 bias-ply tire is the natural starting point for a period-style 1963 Bentley S2. This size preserves the vintage numeric format and supports the traditional visual proportions expected on a large early-1960s Bentley saloon.

From there, the appearance decision usually comes down to blackwall, narrow whitewall, or wide whitewall styling, along with brand and series preference. When exact originality matters, the smartest next step is to compare the car against marque references, photos, and restoration records so the chosen sidewall treatment matches the way the particular car is being restored.

Tire construction changes more than ride characteristics on a restored 1963 Bentley S2; it also changes the visual impression of the car. A bias-ply 820-15 maintains the vintage format and sidewall character most closely associated with the period, while radial equivalents can give the car a different visual feel.

That difference is especially noticeable on a full-size luxury car where the tire sidewall plays a large role in the overall stance. Owners focused on traditional presentation often remain with bias-ply construction, while those considering radial alternatives usually do so with care, balancing appearance against road-use expectations and confirming the wheel and chassis setup before making the change.

Yes, modifications can affect tire fitment on a 1963 Bentley S2 even when the nominal tire size remains 820-15. Changes to wheel width, wheel offset, suspension height, steering components, or body clearances can alter how much space the tire has and how it sits on the car.

That is especially important if the Bentley no longer has its original wheel setup or if a radial equivalent is being considered. Any changed component should prompt a fresh check of wheel diameter, rim width, sidewall clearance, and turning clearance, because a correct-looking tire size on paper does not eliminate the need to verify the actual car.

Before driving a 1963 Bentley S2 on new tires, inspect the wheels for correct diameter and condition, confirm proper mounting, and look over the suspension and steering for obvious wear or looseness. Tire pressure, valve stems, and clearance at full steering lock also deserve attention before the first longer outing.

A collector Bentley often spends long periods parked, so the rest of the chassis may need just as much scrutiny as the tires themselves. It is wise to check for rubbing, uneven stance, unusual vibration, and any sign of air loss during the first drives, then recheck pressure and wheel security once the car has been driven and settled.

820-15 tires on a collector 1963 Bentley S2 should be maintained with regular pressure checks, periodic visual inspection, and careful storage habits. Even when tread wear is minimal, vintage-use cars can develop issues from age, inactivity, heat, sunlight, and long static loading on the same part of the tire.

A good routine is to inspect for cracking, cuts, bulges, and slow air loss before road use and after extended storage. The car should also be kept in a clean, dry environment away from prolonged ozone and direct sun when possible. Occasional movement, proper inflation, and prompt attention to any vibration or pull help preserve both tire life and driving confidence.
