1963 Bristol 408 Tires

The 1963 Bristol 408 uses two primary tire sizes: 600-16 in bias-ply construction and 175R16 in radial construction. Both sizes are associated with the Bristol 408 Base and both use a 16-inch rim, so the fitment question is really about construction choice rather than different wheel diameters.

A Bristol that remains on a traditional bias-ply setup calls for a 600-16 tire, while a car set up for radial construction uses 175R16. The next step is checking what wheels are actually on the car and whether the goal is a period-style presentation, a radial-driving setup, or a restoration that stays close to the car’s established tire profile.

The 1963 Bristol 408 uses a 16-inch rim diameter. Both primary tire sizes tied to the car, 600-16 and 175R16, are built for that same 16-inch wheel diameter, so there is no change in rim diameter between the bias-ply and radial fitments.

Even with the correct 16-inch diameter, wheel details still matter before choosing a tire. Collector cars sometimes carry replacement wheels, and width differences can affect how a tire sits and performs. A quick check of the actual wheel size on the car helps keep the selection aligned with the intended construction, overall appearance, and available tire specifications.

The 1963 Bristol 408 Base is associated with both primary sizes used on this model: 600-16 bias-ply and 175R16 radial. That means the Base sub-model does not introduce a separate trim-specific tire size, but it does leave room for a meaningful choice between two different construction types.

For an owner, that makes the decision less about trim identification and more about the car’s current wheel and tire setup. A Bristol being preserved with a traditional look may stay with 600-16 bias-ply tires, while a car already running a radial arrangement should be evaluated around 175R16 and the wheel dimensions that support that setup.

For the 1963 Bristol 408, 600-16 is a bias-ply tire size. It uses the older numeric sizing format common to many vintage vehicles, where the first number refers to nominal section width and the second number identifies the 16-inch rim diameter.

That matters because a 600-16 bias-ply selection keeps the car in a more traditional construction style and opens the broadest range of period-style sidewall choices. Before changing away from that setup, confirm the wheel dimensions, the car’s present stance, and whether the goal is originality in feel and appearance or a move toward radial construction.

The 1963 Bristol 408 can be fitted with either 600-16 bias-ply tires or 175R16 radial tires. Bias-ply construction suits buyers pursuing a more traditional presentation, while the radial option is the construction choice for owners setting the car up around a more modern tire format on the same 16-inch rim diameter.

The right answer depends on how the car is being used and how closely the owner wants to stay with a period-style look. Construction changes should be approached carefully by checking wheel width, overall tire dimensions, and clearance at the fenders and steering components, especially if the Bristol has had wheel, suspension, or ride-height changes over time.

Before converting a 1963 Bristol 408 from 600-16 bias-ply tires to a radial setup such as 175R16, start by confirming that the car still has the correct 16-inch wheels and that the wheel width is appropriate for the radial tire being considered. It is also important to compare the car’s present tire dimensions and stance with the intended radial setup.

Clearance should be checked at full steering lock and through normal suspension travel, since an older grand touring car may have small variations from side to side or from prior repairs. Tire choice should also match how the car is used, because a restoration-focused Bristol may call for a different approach than one prepared mainly for regular road miles.

Start with the basics: the tire must be a true 600-16 bias-ply and it must suit the 16-inch wheel on the car. From there, the key differences are brand, tire series, sidewall style, and supporting specifications such as rim-width guidance and load figures where those are stated.

A 1963 Bristol 408 often rewards a careful balance between appearance and use. Blackwall tires give a restrained look, while wide whitewall and double-whitewall versions create a stronger period-style presentation. It also helps to compare whether the tire is part of a classic passenger-car line or a military or truck-oriented series, since tread character and visual tone can differ noticeably.

For the 1963 Bristol 408, the available 600-16 bias-ply choices include blackwall, wide whitewall, and double-whitewall sidewall styles. Those options create very different visual results even when the size remains the same, so sidewall treatment becomes one of the most important appearance decisions on this car.

A blackwall usually gives the Bristol a more understated and sporting presentation, while whitewall and double-whitewall tires lean harder into formal early-1960s styling. Since sidewall treatment changes the car’s look so dramatically, it is worth matching the tire to the vehicle’s paint, trim, and restoration direction rather than choosing only by brand or tread pattern.

The 1963 Bristol 408 has 600-16 tire options from BFGoodrich, Coker Classic, Avon, Firestone, Goodyear, Lester, Excelsior, STA, Camac, and Ford Script. Most of those choices are bias-ply offerings, and they span several different tire series and sidewall presentations rather than one single style of replacement.

Brand selection should be treated as part of a broader fitment decision, not the whole decision by itself. Compare the specific series, whether the tire is blackwall or whitewall, and any rim-width or load information that matters for the wheel on the car. That approach keeps the focus on compatibility and appearance instead of relying on the name on the sidewall alone.

For a period-style 1963 Bristol 408, the 600-16 bias-ply size is the natural starting point because it preserves the traditional construction and vintage numeric sizing associated with the car. Within that size, several brands and tire series are available, giving room to shape the car’s visual character without changing the basic fitment.

The final choice depends on how formal or understated the restoration is meant to look. A blackwall creates a cleaner, more restrained appearance, while wide whitewall and double-whitewall versions add stronger vintage presence. If exact originality matters down to sidewall treatment, marque references and period photographs are worth consulting before settling on one presentation.

Tire construction changes more than driving feel on a restored 1963 Bristol 408; it also changes the car’s visual language. A 600-16 bias-ply tire gives the car a more traditional vintage profile, while a 175R16 radial introduces a later-style sizing convention and a different presentation, even though both use a 16-inch rim.

That visual difference is especially important on a hand-built British grand tourer where wheel and tire proportion strongly influence the finished stance. Owners aiming for a restoration-oriented look usually begin with the bias-ply format, then narrow the choice by sidewall style. Radials can still be considered, but they should be chosen with a clear eye toward how they alter the car’s appearance.

Yes, modifications can affect tire fitment on a 1963 Bristol 408 even when the nominal tire size stays the same. Aftermarket wheels, changes in wheel width, suspension work, ride-height alterations, or body repairs can all influence how a 600-16 or 175R16 tire sits within the wheel opening and how much clearance remains.

That is why an older Bristol should be measured as it exists today rather than judged only by model-year fitment. Steering clearance, fender clearance, and the relationship between tire and wheel all deserve a fresh check. A car restored years ago or updated by a previous owner may need a different evaluation than one that remains closer to original specification.

Before driving a 1963 Bristol 408 on new tires, inspect the wheels for condition, verify proper mounting on the 16-inch rims, and make sure the tires have adequate clearance through full steering travel. It also helps to check alignment basics, valve stems, and whether the suspension and steering components are in sound condition.

A collector car that has seen limited use deserves extra attention after tire installation. Look for any rubbing marks, confirm stable air pressure, and recheck the tires after the first short drive. That early inspection can catch small clearance or seating issues before the car is taken on a longer outing, especially when changing construction or replacing very old tires.

Tires on a collector 1963 Bristol 408 should be maintained with regular pressure checks, visual inspections for cracking, bulges, cuts, and uneven wear, and periodic review of how the car is stored. Low-mileage vintage cars often age their tires long before they wear them out, so condition matters as much as tread depth.

Storage has a major effect on tire life. Keeping the Bristol away from prolonged sunlight, moisture, heat, and ozone sources helps preserve the rubber, while moving the car occasionally can reduce flat spotting during long periods of inactivity. Any sign of persistent air loss or sidewall deterioration is a reason to stop and evaluate the tire before further road use.
