1965 Bristol 408 Tires

The 1965 Bristol 408 is associated with two primary tire sizes: 175R16 in radial construction and 600-16 in bias-ply construction. Both sizes 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.

That distinction matters because a radial-size Bristol and a bias-ply-size Bristol can look and behave differently. Start by confirming what is currently on the car, then verify the actual wheel size and width before selecting a replacement. On collector cars, previous owners may have changed wheels or construction type, so it is smart to inspect the current setup rather than assume.

The tire fitments associated with the 1965 Bristol 408 use a 16-inch rim. Both the 175R16 radial and the 600-16 bias-ply are built around that same 16-inch wheel diameter, which keeps rim diameter simple even though the tire constructions differ.

Wheel diameter is only part of the picture on a hand-built luxury car such as the Bristol 408. It is still worth checking the actual wheel width and the car's present wheel setup before choosing tires, especially if the car has been restored, modified, or converted from one construction style to another. The right diameter alone does not settle every fitment detail.

The 1965 Bristol 408 Base is associated with the same two primary tire sizes used for the model overall: 175R16 radial and 600-16 bias-ply. There is no separate wheel diameter for the Base sub-model, since both fitments remain on a 16-inch rim.

That means the Base model decision is mainly about the car's present construction type and the look the owner wants to preserve. A Bristol kept in a traditional restoration style may stay with 600-16 bias-ply, while a car already using radial construction may continue with 175R16. Checking the actual wheels and tire-to-body clearance is still the sensible next step.

For the 1965 Bristol 408, 600-16 is the bias-ply fitment. It uses a vintage numeric sizing system in which the 600 indicates an approximate 6.00-inch nominal section width and the 16 identifies the wheel diameter, giving the car a traditional period-style tire format.

That matters because bias-ply construction affects both appearance and setup decisions. Owners choosing 600-16 can compare blackwall, wide whitewall, and double-whitewall styles, but should also confirm wheel width and the overall condition of the suspension and steering components. On a collector Bristol, construction choice should match the car's restoration direction and intended road use.

On the 1965 Bristol 408, 175R16 is the radial fitment. The size uses a Euro-metric radial format, with 175 indicating nominal section width in millimeters, R marking radial construction, and 16 identifying the wheel diameter in inches.

A radial setup changes the tire-selection conversation because the owner is no longer choosing within the older numeric bias-ply system. Before staying with or returning to 175R16, it is worth confirming the actual wheel width, current wheel type, and body and steering clearance on the car. That is especially important on low-volume grand touring cars that may have seen changes over time.

A 1965 Bristol 408 can be approached from either direction because it is associated with both 600-16 bias-ply and 175R16 radial fitment. The right choice depends on whether the car is being kept in a more traditional presentation or maintained around an existing radial setup on 16-inch wheels.

Bias-ply usually appeals more to owners focused on period-style appearance, while radial fitment may suit owners keeping an established radial-equipped car in service. The decision should be made after checking the actual wheels, current tire size, and available clearance rather than by size code alone. Matching all four tires and keeping the construction consistent remains the prudent approach.

Choosing a 600-16 tire for a 1965 Bristol 408 starts with confirming that the car is staying on its bias-ply setup. From there, the main decision points are sidewall style, brand, tire series, and wheel compatibility, since available 600-16 products include blackwall, wide whitewall, and double-whitewall options across several vintage-oriented lines.

A restoration-focused car may point toward a traditional sidewall presentation, while a more understated road car may suit a blackwall. It also helps to compare rim-width specifications, load figures where shown, and tire series character before deciding. On a Bristol, appearance and fitment usually matter just as much as the basic size code.

For the 1965 Bristol 408's 600-16 bias-ply fitment, available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those choices give the car noticeably different visual character, from a restrained touring look to a more formal restoration-oriented presentation on a 16-inch wheel.

Sidewall style should be chosen with the car's finish, trim, and overall restoration direction in mind rather than by size alone. A whitewall can change the car's presence significantly, while blackwall keeps the look simpler and more understated. Since appearance preferences vary widely on British grand touring cars, many owners settle the style decision before comparing brand and series details.

The 600-16 fitment for a 1965 Bristol 408 is available from several brands, including BFGoodrich, Firestone, Goodyear, Coker Classic, Avon, Lester, Excelsior, STA, Camac, and Ford Script. Those brands appear across multiple bias-ply series and sidewall treatments rather than as one uniform type of tire.

Brand choice is best treated as part of a broader comparison that also includes series, sidewall style, and wheel compatibility. Some owners begin with the visual goal, such as blackwall or whitewall, then narrow the selection by series and specifications. That approach usually works better than choosing by brand name first and trying to force the look afterward.

For a period-style 1965 Bristol 408, the 600-16 bias-ply fitment is the more traditional starting point. Its vintage numeric size format and available sidewall treatments suit the kind of visual character many owners want on a mid-1960s hand-built British grand touring car.

The exact choice within 600-16 depends on how formal or understated the finished car should look. Blackwall keeps the presentation restrained, while whitewall variations add more visual emphasis. When exact originality matters, the final decision should be cross-checked against Bristol-specific historical references and the car's own restoration goals rather than appearance alone.

Tire construction has a visible effect on a restored 1965 Bristol 408 because the car is associated with both 600-16 bias-ply and 175R16 radial fitment. A bias-ply setup generally preserves a more traditional vintage presentation, while a radial setup reflects a different sizing convention and visual character on the same 16-inch wheel.

That difference is one reason tire selection should be part of the restoration plan rather than an afterthought. Construction changes can alter the way the car sits visually, especially when paired with different sidewall styles. On a low-production British car, choosing the tire format early helps keep the wheel, stance, and overall appearance moving in the same direction.

Modifications can affect tire fitment on a 1965 Bristol 408 even when the tire still appears to be the correct size. Changes to wheel width, wheel offset, ride height, suspension parts, or body clearance can all alter how a 175R16 radial or 600-16 bias-ply sits and moves within the wheel opening.

That is why a modified Bristol should be checked at the wheel rather than judged by catalog size alone. Look at steering lock clearance, fender space, and the present wheel dimensions before replacing tires. A collector car may also carry older modifications that are easy to overlook, especially if the work was done many years ago.

Before driving a 1965 Bristol 408 on new tires, inspect the wheels for correct diameter and condition, then confirm that the tires are properly seated and inflated. It is also smart to check suspension bushings, steering components, and brake condition so the car can take advantage of the fresh tires safely and predictably.

A short road test should follow, with attention paid to vibration, pulling, rubbing, and any sign of clearance issues at full steering lock. On a low-use collector car, the rest of the chassis may have aged even when mileage is low. New tires are only one part of making an older Bristol ready for regular road use.

600-16 tires on a collector 1965 Bristol 408 should be maintained with regular pressure checks, visual inspections, and clean storage habits. A bias-ply collector tire can spend long periods parked, so sidewall cracking, tread aging, flat spotting, and slow air loss deserve more attention than they might on a frequently driven modern vehicle.

Storage conditions matter almost as much as mileage. Keeping the car away from prolonged sunlight, excess heat, standing moisture, and ozone sources helps preserve the tires between drives. It also pays to inspect the spare and to look over all four road tires before each outing, especially before a longer tour or seasonal return to the road.
