1963 Bristol 407 Tires

A 1963 Bristol 407 uses either a 175R16 radial tire or a 600-16 bias-ply tire. Both are 16-inch fitments, and both apply to the Bristol 407 Base, so the car does not require a different size simply because of the sub-model name.

The practical choice is deciding which construction belongs on your car and confirming that the wheels match the tire you plan to use. A car that has been restored, re-wheeled, or converted in the past may not still be set up exactly as expected, so checking wheel width, overall clearance, and the current tire type is a smart first step.

The 1963 Bristol 407 uses a 16-inch rim diameter with both of its primary tire sizes. That shared rim diameter applies whether the car is using the 175R16 radial fitment or the 600-16 bias-ply fitment.

Rim diameter is only part of the fitment picture on a collector car. The wheel’s actual width still matters, especially when comparing bias-ply and radial setups, and any past wheel changes can affect which tire choice makes sense. Measuring the wheels already on the car is worthwhile before settling on a new set.

On a 1963 Bristol 407, 600-16 is a vintage numeric bias-ply size. The 600 refers to an approximate 6.00-inch nominal section width, while the 16 identifies the wheel diameter in inches.

That size format is different from a modern metric radial marking, so it helps to treat it as a traditional bias-ply fitment rather than trying to compare the numbers directly. If the car is being kept in a period-style presentation, 600-16 is the size to review closely, along with the available sidewall treatments and wheel compatibility.

For the 1963 Bristol 407, 600-16 is a bias-ply tire size. The radial fitment associated with this car is 175R16, so the two sizes represent different construction paths on the same 16-inch rim diameter.

That distinction matters because a bias-ply tire changes both the look and the setup compared with a radial. Anyone choosing between them should look at the car’s current wheels, the type of driving planned, and whether the goal is a more traditional period-style presentation or a radial-equipped road car with the proper wheel and clearance checks.

A 1963 Bristol 407 can be fitted with either 600-16 bias-ply tires or 175R16 radial tires. The right choice depends on how the car is configured now and whether the priority is maintaining a traditional vintage presentation or running the car with a radial construction setup.

Bias-ply and radial tires should be treated as distinct fitment directions rather than casual substitutes. Before changing construction, inspect the actual wheel dimensions on the car and check clearance around the fenders and suspension. A Bristol that has gone through restoration work over the years may deserve a closer look before making the switch.

Before converting a 1963 Bristol 407 from 600-16 bias-ply tires to 175R16 radial tires, start by confirming the wheel diameter and actual wheel width. The car uses a 16-inch rim diameter, but the wheel still needs to suit the radial tire’s fitment requirements.

It also helps to inspect steering and fender clearance, suspension condition, and the car’s present ride height before committing to the change. A radial conversion should be approached as a full fitment check rather than a simple tire swap, especially on a low-production grand touring car that may have seen wheel or suspension changes over time.

Start with the basics: 600-16 is the Bristol 407’s vintage numeric bias-ply size, so the tire should match the car’s intended construction, wheel diameter, and overall presentation. Within that size, choices vary by brand, tire series, sidewall style, rim-width specification, weight, and load figures where those are stated.

Selection becomes easier once the goal is clear. A restoration-oriented car may lean toward a traditional blackwall or whitewall treatment, while a regularly driven car may call for closer comparison of wheel compatibility and product specifications. Looking at the tire series and sidewall appearance together usually gives a more useful answer than focusing on brand name alone.

In 600-16, sidewall choices for the 1963 Bristol 407 include blackwall, wide whitewall, and double-whitewall styles. Those options create noticeably different visual presentations even when the tire size and basic construction remain the same.

The best sidewall choice depends on how the car is being presented rather than on fitment alone. A blackwall usually gives a restrained, traditional look, while whitewall and double-whitewall treatments make a stronger visual statement. Because sidewall style can change the character of the car so much, it is worth matching that decision to the restoration theme before comparing individual tires.

The 600-16 fitment for the 1963 Bristol 407 is available from BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those brands appear across several bias-ply tire series and sidewall treatments, so brand choice is only one part of the selection process.

A useful comparison looks at the whole package: tire series, sidewall appearance, stated rim-width range where given, and other product details such as weight or load specification. That approach is especially important on a specialty car like the Bristol 407, where the chosen tire needs to support both the car’s appearance and the wheel setup actually on the vehicle.

For a period-style 1963 Bristol 407, the 600-16 bias-ply size is the natural starting point because it preserves the vintage sizing format and traditional construction. Within that size, the visual result can still vary significantly depending on whether the car is fitted with blackwall, wide whitewall, or double-whitewall tires.

The most appropriate choice depends on the exact restoration direction of the car rather than on size alone. When strict originality matters, it is wise to compare your car against marque references, period photography, or other authoritative Bristol-specific material. That extra step helps separate a broadly period-style tire choice from one intended to mirror a more exact historical presentation.

Tire construction changes the look of a restored 1963 Bristol 407 as well as the way the size is presented on the sidewall. A 600-16 bias-ply setup delivers a distinctly vintage tire format, while a 175R16 radial introduces a later metric-style marking and a different visual character even though both use a 16-inch rim.

That makes construction choice part of the restoration conversation, not just a mechanical decision. A buyer aiming for a traditional grand touring appearance may prefer to begin with the bias-ply path and then choose the sidewall style carefully. A radial setup can still suit the car well, but it should be selected with an eye toward the finished look.

Yes, modifications can affect tire fitment on a 1963 Bristol 407 even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, altered ride height, suspension work, or body modifications can all influence how a 175R16 or 600-16 tire sits and clears the car.

A collector car that has changed hands over decades may no longer wear its original-style wheel setup, so measuring what is actually on the car matters. Checking steering clearance, fender room, and suspension condition before mounting new tires helps avoid choosing a size or construction that looks right on paper but conflicts with the vehicle’s current configuration.

Before driving a 1963 Bristol 407 on new tires, inspect the wheels for correct diameter and overall condition, then verify that the tires are mounted in the intended size and construction. It is also worth checking valve stems, balance, inflation, and whether the tires clear the body and suspension through the steering range.

A road test should begin gently, especially on a car that has been parked or restored. Pay attention to pull, vibration, unusual rubbing, or air loss after the first miles. On an older grand touring car, those basic checks are just as important as choosing the right tire size, because roadworthiness depends on the whole wheel-and-tire system.

Tires on a collector 1963 Bristol 407 should be inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, even if the car is driven only occasionally. Pressure checks matter on low-mileage cars because a tire can age or lose air long before the tread shows much use.

Storage conditions also play a role in long-term tire health. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires between drives. A Bristol that spends much of its time parked should still have its tires and wheels looked over before road use, particularly ahead of a longer outing.
