1963 Bristol Tire Fitment Guide

1963 Bristol vehicles use two tire sizes: 175R16 and 600-16. Both sizes fit the 1963 Bristol 407 and 1963 Bristol 408, so there is no model-only split within the year. Both also mount on 16-inch wheels, and the 600-16 bias-ply products with published fitment guidance suit rim widths from 4.00 to 4.50 inches.

That means most owners start by choosing the type of driving experience they want rather than sorting through different model-specific wheel diameters. A 600-16 keeps the car in a traditional bias-ply format, while a 175R16 moves toward a radial layout. Before ordering, verify the wheel width actually on your Bristol, since many hand-built British cars have been changed over the years.

On a 1963 Bristol tire, 600-16 is a numeric bias-ply size. The 6.00 designation is the nominal section width in inches, and the 16 is the wheel diameter in inches. For 1963 Bristol applications, 600-16 is used on both the 407 and 408 and appears in period-style bias-ply products with blackwall or wide whitewall sidewalls.

This format is common on mid-century cars and reads very differently from later metric radial sizing. If your Bristol is being restored with an emphasis on era-correct look and construction, 600-16 is usually the first place to focus. It is still important to compare the wheel width against the tire’s approved range, especially on cars that may have had replacement wheels fitted during past restoration work.

Yes. The 1963 Bristol 407 and 1963 Bristol 408 both use the same two sizes: 175R16 and 600-16. That shared fitment means tire selection at the year-and-make level is straightforward, because you are not sorting between different wheel diameters or exclusive model-only sizes within the 1963 Bristol range.

The practical difference comes down to how you want the car to look and drive. Owners pursuing a traditional restoration often lean toward the numeric bias-ply size, while owners who prioritize contemporary road manners often consider the radial size. Once you know which direction you want to go, the next step is checking the actual wheel on the car and matching the tire to that wheel correctly.

For a 1963 Bristol, the decision between 175R16 and 600-16 is mostly about construction type and the character you want from the car. The 175R16 is a radial fitment, while the 600-16 is a bias-ply fitment used on both the 407 and 408. Since both sizes mount on 16-inch wheels, this is not primarily a question of one model requiring a different diameter.

A Bristol restored for period appearance usually points owners toward the 600-16, especially when sidewall style matters to the overall presentation. A Bristol driven regularly on modern roads may benefit from the radial format’s more contemporary feel. The right choice depends on whether your priorities are authenticity, driving character, or a blend of both, and that choice should be made before narrowing down brands or sidewall style.

1963 Bristol tires in 600-16 are available in blackwall and wide whitewall form. BFGoodrich and Firestone offer wide whitewall versions in this size, while Coker Classic and Avon are available as blackwalls. Those sidewall choices sit within the same bias-ply size, so the decision is about appearance rather than changing the basic wheel diameter.

For a British grand touring car like a 1963 Bristol, blackwall tends to be the most restrained and broadly era-appropriate visual choice, especially for owners seeking an understated factory-style presentation. Wide whitewalls create a stronger period custom or luxury look and should be chosen carefully to suit the way the car is being restored. Matching the sidewall style to the car’s intended presentation is just as important as choosing the right size.

1963 Bristol vehicles have 600-16 tire options from BFGoodrich, Coker Classic, Avon, and Firestone. Those brands cover both blackwall and wide whitewall treatments in the bias-ply size used by the Bristol 407 and 408. Avon’s 600H16 93H also adds an H speed rating, which carries a 130 mph ceiling.

Brand choice often follows the kind of Bristol you are building. Some owners focus on a distinctly British flavor, while others prioritize a particular sidewall look associated with American classic tire styling. Once you have settled on construction type and appearance, comparing the available brand families within that size becomes much easier and keeps the search aligned with the character of the car.

For 1963 Bristol applications in 600-16, the published rim width range is 4.00 to 4.50 inches on a 16-inch diameter wheel. That guidance applies to the bias-ply products in this size used on both the 407 and 408. The year-make fitment also includes 175R16 on a 16-inch wheel, so wheel diameter remains consistent across both sizes.

Rim width matters because it affects the tire’s profile, tread shape, and overall fit on the wheel. Even when the car still wears original-looking 16-inch wheels, it is wise to measure the wheel rather than relying on assumption, especially on a hand-built car that may have seen decades of maintenance and parts changes. Confirming the wheel first prevents choosing a tire that is technically the right diameter but wrong for the wheel width.

Tube requirement should be confirmed product by product on a 1963 Bristol. The 600-16 bias-ply products here do not carry a universal tube-type or tubeless marking across every offering, so it is best to verify the exact sidewall marking and the wheel design before finalizing the setup. That matters on both the 407 and 408 because they share the same tire sizes.

Older wheel designs, wheel condition, and the specific construction of the tire all influence whether a tube is appropriate. A restorer should also look closely at the valve stem arrangement and the condition of the wheel’s bead seat before making the decision. Treat tube choice as part of the wheel-and-tire system rather than as a simple property of the size name alone.

In many cases, yes, because both 175R16 and 600-16 for 1963 Bristol vehicles use a 16-inch rim diameter. That means the original 1963 Bristol wheel diameter is compatible with either size in principle on both the 407 and 408. The remaining question is whether the actual wheel width on the car matches the tire you intend to use.

That distinction is important because shared diameter does not automatically mean every 16-inch tire is ideal on every 16-inch wheel. If your Bristol still wears its original wheels, measure them and inspect them for straightness, corrosion, and proper bead condition before fitting new tires. If the wheels are replacements, the need to verify width becomes even more important before choosing between bias-ply and radial construction.

A 1963 Bristol should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Tire pressures should be maintained during storage, and the car should be moved periodically or supported in a way that reduces long-term static loading. Bias-ply tires such as 600-16 are especially prone to temporary flat-spotting during long periods of inactivity.

Good storage habits preserve both appearance and road feel when the car comes back into service. If your Bristol sits for months at a time, a quick inspection and a short warm-up drive can help a bias-ply tire settle back into shape before extended use. Keeping the tires clean and free from petroleum-based dressings also helps protect the sidewalls over time.

On a 1963 Bristol, tire life is usually judged more by age and condition than by mileage. Collector-car tires should be inspected regularly after about five to seven years of service, and many owners begin serious replacement consideration as tires approach ten years from the DOT date code, even if tread depth still looks acceptable. That guideline applies whether the car uses radial 175R16 or bias-ply 600-16 tires.

Low annual mileage can hide age-related deterioration, especially on cars that spend long periods parked indoors. Sidewall cracking, hardening, irregular wear, and repeated air loss matter more than odometer readings on a Bristol that only sees occasional touring. A tire that still looks presentable in the garage may no longer be the right choice for high-speed or long-distance driving once age becomes the dominant factor.

Tires on a 1963 Bristol should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, embedded debris, and signs of air loss. If the final setup uses tubes, valve stems and stem grommets also deserve close attention because leaks can develop there even when the tread and casing still appear sound.

Frequent inspections are especially worthwhile on a grand touring car that may sit for stretches and then be asked to cover meaningful road miles in a single trip. A quick walkaround takes only a minute and often catches age-related problems before they become roadside issues. It is also a good time to confirm cold inflation pressure and to inspect the spare, which is easy to overlook on a seldom-driven collector car.

A 1963 Bristol 407 would have been associated with period-correct tire practice from the early 1960s, when bias-ply construction was still widely used even as radials were gaining ground in Europe. Within the 1963 Bristol range, both 600-16 bias-ply and 175R16 radial fit the 407. That means the right choice for originality depends on the exact market presentation, restoration philosophy, and any surviving factory or ownership history tied to the individual car.

Owners chasing strict historical accuracy should treat 600-16 bias-ply as the natural starting point and then verify details with Bristol specialists, period road tests, original handbooks, and marque clubs. If the car has a long, well-preserved history, existing wheel and tire evidence may also help guide the decision. Sidewall treatment matters too, since blackwall and whitewall create very different period impressions on a hand-built British GT.

Correct tire fitment matters a great deal when showing a 1963 Bristol, especially in judged classes that value authenticity. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall appearance suit the car’s era and presentation. A radial may be acceptable on a touring-driven car, but a bias-ply often looks more appropriate on a Bristol restored to a period-correct standard.

What counts as correct can vary by event, country, and judging philosophy, so event-specific standards should be checked before the car is prepared. A blackwall versus wide whitewall decision can also affect how authentic the car appears in a concours setting. If showing is a major priority, settle the originality question first and let that drive the final tire choice rather than working backward from convenience.

The 1963 Bristol 408 sits in the same fitment family as the 407, using 600-16 bias-ply and 175R16 radial sizes on 16-inch wheels. For a car of this era and class, bias-ply construction remains the most traditional historical reference point, while radial sizing reflects the broader transition taking place in European motoring during the period. No original-equipment brand should be assumed without car-specific historical confirmation.

That makes restoration research important if the goal is a truly authentic 408. Period photos, surviving factory literature, and Bristol club knowledge can help narrow whether a particular car is better presented on blackwalls or another sidewall treatment and whether radial use is appropriate for its history. When authenticity is the target, tire choice should support the story of the individual car, not just the broad year-and-make fitment.

1963 Bristol tires can be suitable for highway driving when the tire is in good condition, correctly fitted, and used within its design limits. The 600-16 size includes H-rated examples with a 130 mph ceiling, while other products in that size do not necessarily carry the same marking. The 175R16 radial and 600-16 bias-ply also deliver different road manners, even though both fit the 407 and 408 on 16-inch wheels.

On a car like a Bristol, overall mechanical condition matters just as much as tire capability. Brakes, suspension, steering, alignment, and wheel condition all influence highway confidence on a low-volume 1960s grand tourer. A tire should be chosen for the way the car will actually be driven, and any old or questionable casing should be replaced before asking the car to cover long highway distances.

Inflation pressure for a 1963 Bristol should be set by the tire manufacturer’s guidance and checked against the original owner’s literature for the car. In 600-16 bias-ply fitments, several products carry a 1400-pound load rating at 32 psi, while the Avon 600H16 is rated at 1,433 pounds. Those figures describe the tire’s rated load relationship and should not be transferred automatically to another size or product.

The safest approach is to start with the vehicle’s factory recommendation when available and then make sure the exact reproduction or specialty tire you choose is being used within its own approved operating range. Pressure should always be checked cold, and the same number should not be assumed correct simply because two tires share a 16-inch rim diameter. Tire construction and product design still matter.

Before a longer drive in a 1963 Bristol, inspect each tire for cracking, cuts, bulges, punctures, irregular wear, and proper cold inflation pressure. Check the spare as well, since a seldom-used spare is often older than the road tires and may no longer be dependable. If the final tire setup uses tubes, valve stems and any signs of slow leakage should be part of the inspection.

Tires are only one part of the pre-trip check on a 1960s Bristol, but they are one of the easiest places to prevent avoidable trouble. A grand touring car encourages sustained road speeds, so any weakness in the casing, wheel, or valve hardware deserves attention before departure. Combine the tire check with a broader review of brakes, fluids, cooling, and wheel fasteners to prepare the car for a proper long-distance run.
