1963 Bentley Tire Fitment Guide

1963 Bentley vehicles here use one tire size: 820-15. That size fits both the 1963 Bentley S2 and 1963 Bentley S3, and it mounts on a 15-inch rim. Available products for 820-15 are built for rim widths from 6.00 to 6.50 inches, which gives owners a clear wheel-width range to confirm against the actual wheel before choosing a tire.

Because both Bentley models share the same size, the buying decision usually comes down to sidewall style and the kind of restoration presentation you want rather than a model-specific fitment split. If your car still wears its original wheels, confirm the rim width and overall wheel condition first, especially on a luxury car that may have gone through decades of service, storage, or restoration work.

On a 1963 Bentley, 820-15 is a numeric bias-ply tire size. The 8.20 portion refers to the tire’s nominal section width in inches, and the 15 identifies the wheel diameter in inches. Unlike modern metric radial sizing, this format does not spell out an aspect ratio, and the construction here is traditional bias-ply rather than radial.

That matters because a numeric bias-ply size reads differently from a modern tire code and delivers a different driving character as well. For a 1963 Bentley owner, understanding that 820-15 is an era-correct mid-century luxury-car size helps narrow the search quickly, especially when comparing blackwall and whitewall options that all fit the same basic wheel diameter.

Yes. Both the 1963 Bentley S2 and 1963 Bentley S3 use 820-15 tires in this fitment group. There is no split here between the two models by tire size, so you do not need to sort between multiple rim diameters or alternate section widths just to identify the basic fitment.

That shared sizing simplifies the search, but it does not make every tire choice identical in appearance. A narrow whitewall, wide whitewall, or blackwall can change the visual impression of the car quite a bit, particularly on a formal British saloon where stance and sidewall presentation are a major part of the finished restoration.

1963 Bentley tires in 820-15 are available in blackwall, narrow whitewall, and wide whitewall styles. BFGoodrich offers both blackwall and a 1.00-inch narrow whitewall in this size, while US Royal offers a 3.50-inch wide whitewall, and Firestone appears here in blackwall form. All of them share the same basic 820-15 bias-ply fitment.

Sidewall style is often the biggest visual decision on a 1963 Bentley because the fitment itself stays the same across both models. Owners aiming for a restrained European luxury look often lean toward blackwall or a modest whitewall, while a broader whitewall can create a stronger period presentation for a car restored to a distinctly early-1960s luxury aesthetic.

BFGoodrich, Firestone, and US Royal all offer 820-15 tires for 1963 Bentley vehicles. Each brand appears in bias-ply construction, and the available selection spans blackwall, narrow whitewall, and wide whitewall styles depending on the tire. That gives Bentley owners several historically familiar American-brand options in a size appropriate to the period.

Brand choice on a collector Bentley usually comes down to the look you want and the particular sidewall treatment that best complements the car. Since the two Bentley models here share one size, comparing brands is less about chasing a different fitment and more about selecting the presentation that fits your restoration plan, touring use, or show-field goals.

For the 1963 Bentley, BFGoodrich and Firestone both offer 820-15 bias-ply tires with the same 1920-pound load rating at 32 psi and the same 15-inch rim diameter with a 6.00 to 6.50 inch rim-width range. The visible difference is that BFGoodrich appears in both blackwall and 1.00-inch narrow whitewall form, while Firestone appears here in blackwall form. Weight also varies slightly, with the BFGoodrich blackwall at 28 pounds, the BFGoodrich narrow whitewall at 30 pounds, and the Firestone at 33 pounds.

That means the practical comparison is mostly about appearance and brand preference rather than a dramatic fitment change. If you want to stay with a blackwall, both brands cover that need in the same basic size. If you want a modest whitewall without moving away from the 820-15 fitment, BFGoodrich adds that option in the same rim and load category.

The 820-15 tires used on 1963 Bentley vehicles are built for 6.00 to 6.50 inch rim widths and mount on a 15-inch wheel. That range applies across the available products in this size, making rim-width confirmation one of the most important setup checks before final selection. It is a straightforward fitment, but the wheel still needs to match both diameter and width.

On an older Bentley, wheel history matters because a car may have had replacement rims, repaired wheels, or long-stored originals. Measure the wheel or verify stamped wheel information before fitting new tires. Staying within the correct width range helps preserve the intended profile and supports the tire properly without forcing the sidewall into an unsuitable shape.

The 820-15 products for 1963 Bentley vehicles are not marked here with tube-type or tubeless distinctions, so tube choice should be confirmed against the actual tire sidewall marking and the wheel design itself. On a collector car of this era, that is especially important because wheel construction and restoration history can affect whether a tube is appropriate. The basic fitment size alone does not answer the tube question.

A Bentley owner should check both the tire’s marking and the wheel’s condition before final assembly. If the wheel was originally designed around tube-type service, or if there is any doubt about the wheel’s sealing surfaces after decades of use, restoration, or refinishing, discussing the combination with a trusted installer or marque specialist is a smart final step.

A 1963 Bentley should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Bias-ply tires also tend to develop temporary flat-spotting more readily than radials when a heavy car sits for long periods. Clean floors, stable temperatures, and proper inflation all help reduce stress on the tire casing during storage.

If the car will sit for months, move it periodically so the tire is not resting on the same contact patch the entire time, or use appropriate stands if that fits your storage routine. A large luxury saloon like a 1963 Bentley puts considerable static load on each tire, so storage habits matter. Keeping the car sheltered and the tires correctly inflated goes a long way toward preserving ride quality and sidewall appearance.

Tires on a 1963 Bentley should be judged more by age and condition than by mileage, because collector cars often cover limited annual miles. A good rule is to begin careful age-related evaluation around five to seven years and to treat roughly ten years as a point for serious replacement consideration, even if the tread still looks deep. The DOT date code and the tire’s overall condition matter more than odometer readings on a low-use classic.

That approach is especially important on a car that may spend long periods parked between drives or events. Rubber hardens over time, sidewalls can crack, and internal aging does not always show up as obvious tread wear. If a 1963 Bentley still rides on older bias-ply tires, regular age checks are a better guide to service life than waiting for the tread to look worn out.

Tires on a 1963 Bentley should be inspected before every drive and given a more thorough check before any extended outing. Look for sidewall cracking, bulges, embedded objects, irregular wear, and any signs that the tire is losing pressure. On a heavy, refined saloon, even a small issue can affect road manners more noticeably than the owner expects.

A longer pre-drive inspection should also include the spare, valve stems, and the general condition of the wheel itself. Since many collector cars are driven less frequently, problems can develop quietly during storage rather than on the road. Catching age-related damage early is one of the simplest ways to avoid spoiling a tour or risking damage to a restored wheel and fender.

A 1963 Bentley S3 would have been a bias-ply car in period, and the shared 820-15 fitment used across the 1963 Bentley models here aligns with that era of original construction. That means a bias-ply 820-15 is the appropriate starting point for an owner pursuing a historically faithful restoration. Original-equipment branding could vary by market and delivery history, so the safest path is to confirm factory literature or marque-club guidance for the specific car.

For most restorers, size, construction type, and sidewall appearance matter more than chasing a brand name without hard evidence. A 1963 Bentley restored for authenticity usually benefits from staying with the correct numeric bias-ply format and then selecting the blackwall or whitewall treatment that matches the car’s presentation, market, and coachbuilt or standard-body character.

Yes, correct tire fitment matters on a shown 1963 Bentley because judges and knowledgeable enthusiasts notice whether the size, construction, and sidewall style suit the period. An 820-15 bias-ply tire matches the mid-century luxury-car character far more closely than a visibly modern substitute. Sidewall presentation also affects the overall visual balance of the car, especially on a formal saloon with a tall greenhouse and restrained body lines.

The level of scrutiny depends on the event. Some shows care mainly about cleanliness and overall presentation, while marque-focused judging may pay close attention to whether the sidewall style looks appropriate for the model and market. If authenticity is a major goal, consult Bentley and Rolls-Royce club resources before finalizing the tire appearance for a concours-oriented car.

For the 1963 Bentley, BFGoodrich and US Royal both offer 820-15 bias-ply tires with the same 1920-pound load rating at 32 psi and the same 15-inch rim fitment with a 6.00 to 6.50 inch rim-width range. The key difference is sidewall presentation: BFGoodrich appears in blackwall and 1.00-inch narrow whitewall form, while US Royal appears here as a 3.50-inch wide whitewall. Weight also differs slightly, with the BFGoodrich narrow whitewall at 30 pounds and the US Royal wide whitewall at 29 pounds.

For a restoration, that makes this comparison less about the basic fit and more about the visual statement you want the car to make. A modest whitewall can keep the car understated, while a broader whitewall creates a more formal early-1960s luxury look. Either way, both stay within the proper 820-15 bias-ply framework for a period-correct Bentley presentation.

A properly fitted, properly maintained 820-15 bias-ply tire can be suitable for highway driving on a 1963 Bentley when it is in sound condition and used within its intended limits. The products here do not show explicit modern speed-rating letters, so tire condition, inflation, balance, and the overall health of the car matter greatly. On a car of this era, brakes, suspension, steering condition, and alignment are often just as important as the tire itself.

The practical takeaway is to treat the tire as one part of a complete roadworthiness check rather than the only factor. A well-sorted 1963 Bentley is a composed touring car, but it still comes from an era with different mechanical expectations than a modern sedan. Before sustained highway use, make sure the tires are fresh and the chassis systems are equally ready for the trip.

For 1963 Bentley 820-15 tires, the available products carry a maximum load of 1920 pounds at 32 psi. That figure is the tire’s rated load-and-pressure point, not automatically the exact running pressure every Bentley should use in service. Factory recommendations can vary by vehicle weight distribution, driving load, and the way the manufacturer wanted the car to ride and handle.

Start by checking the original owner’s manual or factory placard for the car’s intended operating pressure, then compare that with the reproduction tire’s construction and published limits. Do not transfer a pressure assumption from another size or another luxury car of the period. On a heavy saloon, correct pressure has a direct effect on steering feel, ride quality, and even tread wear over time.

Before a longer drive in a 1963 Bentley, inspect each tire for cracks, cuts, bulges, exposed cords, and uneven tread wear, then verify inflation pressure and look over the valve stems and spare. Since both the S2 and S3 share the same 820-15 size, the core inspection routine is the same across both models. Wheel condition matters too, especially if the car still wears older restored rims.

A longer trip also deserves a broader mechanical check because tire health and vehicle health work together on a classic Bentley. Make sure the steering feels consistent, the suspension is settled, and the brakes are operating evenly before heading out. A stately grand-touring saloon can cover distance beautifully, but only when the tires and the rest of the chassis are equally prepared.
