The 1949 Bristol 401 came from an important postwar moment when Bristol was building refined British grand touring cars with a strong emphasis on engineering, balance, and clean aerodynamic styling. For owners today, that character matters because the car looks and feels right when the tire choice stays in step with its period presentation. The 1949 Bristol 401 uses a 5.75-16 bias-ply tire on a 16-inch rim. That keeps the decision centered on selecting the right period-style tire within the proper size rather than sorting through multiple fitments. For restoration-minded driving and road use alike, wheel condition, tire age, and overall compatibility deserve a careful check before the car goes back into service.
Which Tire Size Is Right for The 1949 Bristol 401
The 1949 Bristol 401 uses one primary tire size: 5.75-16. It is a bias-ply fitment for a 16-inch rim, and the covered sub-model uses the same size, so the main decision is choosing the right period-style tire within that fitment and confirming that the wheels on the car still match the original size and construction approach.
A 5.75-16 tire uses the older numeric bias-ply sizing system, where 5.75 refers to the nominal section width in inches and 16 identifies the wheel diameter. On a 1949 Bristol 401, this is a traditional bias-ply fitment that suits the car's postwar touring-era design and appearance. Buyers looking at this size are usually focused on preserving a proper period-style stance and maintaining compatibility with the intended wheel diameter. Before making a final choice, it is wise to confirm the actual wheel size on the car and inspect for any past wheel or suspension changes that could affect fitment.
Tire fitment is straightforward for the covered 1949 Bristol 401 sub-model. The main value in checking the sub-model is simply confirming that the car falls under the same single-size, 16-inch bias-ply fitment before selecting a tire.

Frequently Asked Questions
Common questions for the 1949 Bristol 401 usually center on the single 5.75-16 fitment, 16-inch rim compatibility, period-style tire selection, restoration appearance, and the basic checks that matter before returning a collector car to road use.
Tire Size & Fitment
What tire size fits a 1949 Bristol 401?
The 1949 Bristol 401 uses a 5.75-16 tire. That is a vintage numeric bias-ply size, and it is the primary fitment for this model on a 16-inch rim.
That makes tire selection more about choosing the right tire within the correct size than sorting through multiple factory fitments. Before replacing old tires, confirm that the car still has 16-inch wheels and has not been altered with different rims, suspension changes, or other modifications that could affect clearance or compatibility.
What size rim does a 1949 Bristol 401 use?
The 1949 Bristol 401 uses a 16-inch rim with its 5.75-16 tire size. The wheel diameter is an essential part of the fitment, because the tire size is built around that 16-inch specification.
Wheel diameter should be verified on the car before ordering tires, especially on a collector vehicle that may have changed hands many times. A tire in the correct vintage size still needs the correct wheel diameter to mount properly, and checking the actual wheels helps avoid mistakes when a car has been modified or fitted with later replacements.
Does the 1949 Bristol 401 Base use the same tire size?
Yes. The 1949 Bristol 401 Base uses the same 5.75-16 bias-ply tire size as the model covered here. There is no separate primary tire size for that sub-model within this fitment range.
That consistency simplifies the search, but it still helps to verify the car's wheels before making a final choice. Older restorations sometimes pick up replacement wheels over time, and even when the sub-model fitment is straightforward, the actual wheel diameter and overall condition of the wheels should be checked before mounting new tires.
Choosing the Right Tire
What should I consider when choosing a 5.75-16 tire for a 1949 Bristol 401?
Start with the correct fitment: 5.75-16 in a bias-ply construction on a 16-inch rim. For a 1949 Bristol 401, the main choice is usually about staying true to the car's period character while selecting a tire that matches the intended use of the vehicle.
A Bristol that is shown, lightly toured, or driven regularly may lead to slightly different priorities, even within the same size. Check the wheel condition, confirm that the car still carries the proper rim diameter, and think about whether appearance, preservation, or regular road use matters most before settling on a specific tire.
How do I choose between the available 5.75-16 tires for a 1949 Bristol 401?
The first step is making sure the tire is the correct 5.75-16 bias-ply fitment for the 1949 Bristol 401. After that, the real comparison usually comes down to overall presentation, how closely the tire suits the car's era, and whether the vehicle is being restored, preserved, or prepared for occasional road use.
It helps to look beyond the size alone and consider the full setup on the car. Wheel condition, suspension health, and how the Bristol is actually driven all matter, because a collector vehicle may spend long periods parked and then return to service, making condition and compatibility just as important as the correct sidewall size.
Why is choosing the correct size important on a 1949 Bristol 401?
The 1949 Bristol 401 was designed around a 5.75-16 bias-ply tire, so the correct size plays a major role in preserving the car's intended stance, wheel compatibility, and overall period character. Using the proper size also keeps the tire matched to the 16-inch rim diameter used on the car.
Even small departures from the intended fitment can create extra questions about wheel width, fender clearance, and the way the car sits. On a restoration-oriented British car like the 401, tire size affects both appearance and practical fitment, which is why confirming the actual wheel setup is worth doing before any replacement tire is chosen.
Restoration & Appearance
Which tire should I choose for a period-style 1949 Bristol 401?
A period-style 1949 Bristol 401 starts with the correct 5.75-16 bias-ply fitment on a 16-inch rim. That sizing and construction align with the car's postwar touring-era character and help preserve the visual balance that suits the 401's refined body lines.
For a restoration-oriented car, staying with the proper size is often just as important as the brand or tread presentation. If exact historical originality is the goal, compare the tire choice against marque references, restoration records, or other authoritative Bristol-specific documentation, since period-style and exact as-delivered specification are not always the same thing.
Does correct tire fitment matter for a 1949 Bristol 401 restoration?
Yes, correct tire fitment matters a great deal on a 1949 Bristol 401 restoration. The proper 5.75-16 bias-ply size supports the car's intended visual proportions and keeps the restoration grounded in the kind of fitment a late-1940s Bristol would have worn.
Tires influence much more than simple road contact. They affect stance, wheel appearance, and how convincing the finished car looks as a complete restoration. Even if the Bristol is driven only occasionally, confirming the correct wheel diameter and using a size that suits the car's era helps avoid a look that feels out of scale or out of period.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1949 Bristol 401?
Yes. Modifications can affect tire fitment on a 1949 Bristol 401 even when the target size remains 5.75-16. Changes to wheels, suspension height, steering components, or body clearance can alter how a vintage-size tire sits and behaves once mounted.
A collector car should always be checked as it currently exists, not just as it left the factory decades ago. If the Bristol has aftermarket wheels or altered suspension, confirm wheel diameter, physical clearance, and general compatibility before selecting new tires so the correct vintage size does not run into avoidable fitment problems.
What should I inspect before driving a 1949 Bristol 401 on new tires?
Before driving a 1949 Bristol 401 on new tires, inspect the wheels for damage or corrosion, confirm the wheel diameter, and make sure the tires are mounted and inflated correctly. It is also wise to look over the suspension and steering, since collector cars may have sat unused for long stretches.
A sound tire installation works best when the rest of the chassis is equally ready for road use. Check for rubbing at full steering lock, watch for signs of air loss after mounting, and inspect the old tires for uneven wear patterns that might point to alignment or mechanical issues needing attention before a longer drive.
How should 5.75-16 tires on a collector 1949 Bristol 401 be maintained?
Collector-car tires in 5.75-16 should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and uneven wear, and protected from long-term exposure to heat, sunlight, moisture, and ozone sources. A 1949 Bristol 401 that is driven occasionally still benefits from routine tire checks between outings.
Long storage periods can be as important as mileage on an older car, so maintenance should include watching for age-related condition changes rather than focusing only on tread depth. Moving the car periodically, keeping the tires clean, and checking pressure before road use all help a lightly used Bristol stay ready for safer and more consistent driving.
