1955 Bentley Continental Tires

The 1955 Bentley Continental uses two primary tire sizes: 650-16 in bias-ply construction and 185R16 in radial construction. Both sizes are associated with the Continental R and both use a 16-inch rim, so the fitment question is less about wheel diameter and more about which construction and sizing system the car is set up to use.

A car that still follows a traditional restoration approach may stay with 650-16, while a car using a classic radial setup may use 185R16. Checking the tires already on the car, the wheel width, and the available clearance around the fender and suspension helps narrow the correct path before choosing a specific product.

The 1955 Bentley Continental uses a 16-inch rim with both of its primary tire sizes. That applies whether the car is fitted with 650-16 bias-ply tires or 185R16 radial tires, so the wheel diameter stays consistent even though the tire construction and sizing format change.

Wheel diameter is only part of the fitment picture, especially when comparing bias-ply and radial choices. It is still important to confirm the actual wheel width on the car, since several 650-16 and 185R16 products call for different rim-width ranges and that affects how confidently a given tire can be matched to the existing wheel.

650-16 is a vintage numeric bias-ply size. The 6.50 refers to the tire's nominal section width in inches, while the 16 identifies the wheel diameter in inches. On a 1955 Bentley Continental, this size represents the traditional bias-ply fitment and is the one most closely associated with a period-style tire presentation.

That size code also signals that modern radial sizing conventions do not apply in the same way. A buyer looking at 650-16 should focus on the construction, sidewall style, and wheel-width requirements of the specific tire, especially if the car has been updated over the years or if maintaining a restoration-oriented appearance is important.

For the 1955 Bentley Continental, 650-16 is a bias-ply tire size. It is the traditional numeric sizing format used on many mid-century luxury and touring cars, and it appears here alongside a separate radial fitment, 185R16, rather than as a radial size itself.

That distinction matters because choosing 650-16 usually means preserving the vintage construction style as well as the visual character that comes with it. Anyone comparing it with 185R16 should look beyond the shared 16-inch rim diameter and confirm wheel width, overall setup, and how closely the car is being kept to a period-style specification.

A 1955 Bentley Continental can be set up with either 650-16 bias-ply tires or 185R16 radial tires, so the better choice depends on how the car is being used and how it is presently equipped. Bias-ply favors a more traditional appearance and vintage construction, while 185R16 gives the car a classic radial fitment on the same 16-inch rim diameter.

The practical decision usually comes down to restoration priorities, road-use expectations, and wheel compatibility. Cars already running radials should have their wheel width checked against the chosen 185R16 product, while cars staying with 650-16 should compare available blackwall and wide whitewall options to match the desired presentation.

The key conversion check is whether the car's wheels and present setup support the 185R16 radial size rather than the 650-16 bias-ply size. Since both use a 16-inch rim, the important differences are the tire construction, the radial product's wheel-width requirements, and how the tire sits within the car's suspension and body clearances.

A careful inspection should include wheel width, steering clearance, fender clearance, and the condition of suspension and steering components before the change is made. It also helps to confirm that all four wheels match and that the car is not carrying older mixed-fitment hardware from past repairs or modifications.

Start with the tire size and construction the car is actually set up to use. A 1955 Bentley Continental may run 650-16 bias-ply tires or 185R16 radial tires, both on 16-inch rims, so the choice begins with construction style, then moves to wheel-width compatibility, sidewall presentation, and the character of the available tire series.

That means a restoration-focused car may lean toward the traditional look of 650-16, while a car already on radials may be better served by selecting among the available 185R16 blackwall options. Product details such as rim-width range, load figures where stated, and intended visual style are more useful than choosing by brand name alone.

Sidewall style depends on which of the Bentley's two tire sizes you choose. The 185R16 radial options are offered in blackwall form, while 650-16 bias-ply tires are available in both blackwall and wide whitewall styles. That gives the car a clear appearance choice between a more restrained radial presentation and a more traditional bias-ply look.

Sidewall treatment can change the personality of a restoration even when the wheel diameter stays the same. Buyers comparing 650-16 products should decide whether the car calls for a plain blackwall or a wide whitewall visual treatment, then confirm that the tire's construction and wheel-width requirements still suit the car's actual setup.

Brand choice is broad for the 1955 Bentley Continental. In 185R16, the available radial brands include Michelin, Avon, and Vredestein. In 650-16 bias-ply, choices include BFGoodrich, Coker Classic, Firestone, Garfield, Excelsior, Lester, Goodyear, STA, and Tornel, spread across several different classic tire series and sidewall treatments.

The most useful way to compare those brands is by the kind of tire each one represents rather than by name alone. Some 650-16 products emphasize blackwall or wide whitewall appearance, while some bias-ply offerings lean toward truck or military-style tread patterns, so matching the tire to the Bentley's intended presentation matters.

For a period-style 1955 Bentley Continental, 650-16 bias-ply is the natural starting point because it preserves the vintage sizing format and the traditional construction associated with the era. That size is available in both blackwall and wide whitewall forms, which gives room to shape the car's visual tone without leaving the correct 16-inch fitment family.

The right version depends on how closely the car is being restored and what kind of presentation the owner wants at a glance. When exact originality matters, it is worth checking marque-specific historical references or restoration records, then comparing those findings with the available bias-ply sidewall and series choices.

Tire construction changes the visual character of a restored 1955 Bentley Continental as much as the size code itself. A 650-16 bias-ply tire gives the car a more traditional mid-century presentation, especially when paired with blackwall or wide whitewall styling, while 185R16 creates a radial look that is still classic but visually more modern in character.

That difference matters because the tire is such a large visual element on a formal grand touring car. Owners aiming for a restoration-oriented result usually decide on construction first, then choose the sidewall style that best supports the body color, wheel treatment, and the overall era impression they want the Bentley to carry.

Yes, modifications can affect tire fitment on a 1955 Bentley Continental even when the tire size appears correct on paper. Changes such as different wheel widths, replacement wheels, suspension alterations, or body and brake updates can influence how either 650-16 bias-ply or 185R16 radial tires sit within the wheel opening and steering range.

A car that has been altered over the years should be checked at full steering lock and through normal suspension travel before a new set is chosen. Clearance around fenders, inner wheelhouses, and suspension parts matters more once the car no longer reflects its original wheel and chassis setup.

Before driving a 1955 Bentley Continental on new tires, inspect the wheels for damage or corrosion, confirm the tire size and construction match the car's setup, and verify that all tires are properly seated and inflated. It is also smart to look over valve stems, wheel fasteners, and the basic condition of steering and suspension components.

A short, careful road test is the best next step after installation. Pay attention to rubbing, pulling, vibration, and any sign of contact at parking-lot steering angles, especially if the Bentley has not been driven recently or if it has changed from one construction type to another.

Collector-car tires on a 1955 Bentley Continental should be maintained with regular pressure checks, visual inspections, and close attention to age and condition. That applies to both 650-16 bias-ply tires and 185R16 radials, since low annual mileage does not prevent deterioration from time, heat, sunlight, ozone, or long stationary periods.

Routine checks should include tread condition, sidewall cracking, bulges, cuts, and any sign of air loss before the car goes back on the road. Storage habits matter too, so keeping the Bentley in a clean, dry space and moving it periodically can help reduce stress on the tires during long periods of inactivity.
