The 1951 Bristol 402 belongs to a small, highly regarded group of postwar British grand touring cars that combined restrained coachwork with a distinctly sporting character. For owners today, tire choice has a real effect on how the car looks, sits, and feels on the road, especially when originality of presentation matters. The 1951 Bristol 402 uses a 550-16 bias-ply tire on a 16-inch rim, keeping selection centered on a traditional vintage fitment rather than a modern radial conversion. Available choices include blackwall and wide whitewall styles from Excelsior, Avon, BFGoodrich, and Firestone. The key decision is choosing the right period-style appearance and verifying wheel condition before regular driving.
Which Tire Size Is Right for The 1951 Bristol 402
The 1951 Bristol 402 uses one primary tire size: 550-16. This is a bias-ply fitment on a 16-inch rim, and the covered 402 Base model shares that same size, so the main choice is not between multiple fitments but between sidewall style, brand, tire series, and how closely the tire suits your restoration or road-use goals.
A 550-16 size is a vintage numeric bias-ply designation in which the 5.50 refers to the nominal section width in inches and the 16 identifies the wheel diameter. On a 1951 Bristol 402, that keeps the car in its traditional bias-ply construction and preserves the narrow, upright look associated with early postwar European touring cars. Available choices include blackwall and wide whitewall versions in series such as Excelsior Bias Ply, Tourist Crossply, Silvertown Classic Bias Ply, and Firestone Classic Bias Ply. This size makes the buying decision more about appearance, brand preference, and wheel compatibility than about sorting through multiple primary fitments.
Fitment for the covered 1951 Bristol 402 sub-model is straightforward. The 402 Base uses the same primary tire size, so selection comes down to choosing the right 550-16 bias-ply tire and matching its appearance and specifications to the car’s wheels and intended use.

Tire Size & Fitment
What tire size fits a 1951 Bristol 402?
The 1951 Bristol 402 uses a 550-16 tire. This is the primary fitment for the model, and it is a bias-ply tire size intended for a 16-inch wheel, keeping the car in its traditional vintage sizing format rather than a modern metric system.
That means the main fitment question is usually not choosing between multiple sizes, but confirming that the car still has the correct 16-inch wheels and an original-style wheel width. If the car has been modified over the years, check the wheel stamping or measure the rim before selecting among the available 550-16 options.
What size rim does a 1951 Bristol 402 use?
The 1951 Bristol 402 uses a 16-inch rim with its 550-16 tire size. Product specifications in this size also show rim-width ranges such as 3.25 to 4.00 inches on some options, which is useful when comparing an existing wheel to the intended tire.
Rim diameter should be confirmed first, especially on an older collector car that may have had wheel changes at some point. After that, verify that the wheel width is appropriate for the specific tire you are considering, since matching the rim properly helps preserve the tire’s shape, clearance, and vintage road manners.
Does the 1951 Bristol 402 Base use the same tire size?
Yes. The 1951 Bristol 402 Base uses the same 550-16 bias-ply tire size as the core model fitment. There is no alternate primary size shown for the covered sub-model, so the fitment remains consistent rather than varying by trim or configuration.
That consistency simplifies the search, but it does not remove the need to inspect the actual car. A Bristol that has seen wheel replacement, brake work, or long-term storage may still need wheel-diameter confirmation and a close check of rim condition before new tires are installed for road use.
Choosing the Right Tire
What should I consider when choosing a 550-16 tire for a 1951 Bristol 402?
Start with the basics: correct 550-16 sizing, bias-ply construction, and a 16-inch wheel that matches the tire’s intended rim-width range. From there, the choice usually comes down to the look you want, the tire series you prefer, and details such as weight or load capacity when those specifications are available.
A Bristol 402 often benefits from a tire that matches its understated postwar character, so sidewall treatment matters as much as brand. Blackwall tires give a restrained touring appearance, while wide whitewalls create a more formal period-style presentation. It also helps to compare wheel condition and intended driving use before settling on a specific product.
What sidewall styles are available for 1951 Bristol 402 tires?
The available 550-16 tires for a 1951 Bristol 402 come in both blackwall and wide whitewall styles. That gives owners a meaningful appearance choice within the correct vintage size, without changing the basic bias-ply construction or the 16-inch rim requirement.
Blackwalls tend to suit a subtle, sporting presentation, while wide whitewalls lean more toward a formal restoration-oriented look. Neither appearance should be assumed to be factory-correct without vehicle-specific historical confirmation, but both are legitimate style directions within the proper size. Choosing between them usually depends on how the car is finished and how period-minded the overall build will be.
What brands offer tires for the 1951 Bristol 402?
The 1951 Bristol 402 has 550-16 tire options from Excelsior, Avon, BFGoodrich, and Firestone. These choices remain within the same core vintage size and bias-ply format, while giving owners different brand families and tire series to compare for appearance and specification details.
Brand choice should be approached as a matter of product character rather than brand ranking. One tire may offer a blackwall presentation, another a wide whitewall, and some include published rim-width guidance or load information. Comparing those specifics against the car’s wheels and the intended finished look usually leads to a more useful decision than choosing by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1951 Bristol 402?
A period-style 1951 Bristol 402 typically starts with the correct 550-16 bias-ply size. That keeps the car in a traditional vintage construction and preserves the narrow-profile visual character that suits an early 1950s Bristol far better than an obviously modern metric tire treatment would.
The final choice depends on the look of the specific restoration. A blackwall tire gives a cleaner, more restrained sporting presentation, while a wide whitewall changes the car’s visual emphasis considerably. If exact historical accuracy is important, compare the tire choice against period photos, marque references, and restoration records for the individual car before deciding.
Does correct tire fitment matter for a 1951 Bristol 402 restoration?
Yes, correct tire fitment matters a great deal on a 1951 Bristol 402 because tire size and construction strongly influence stance, wheel-well appearance, and the car’s overall period impression. Staying with the proper 550-16 bias-ply format helps maintain the visual proportions expected of a postwar Bristol.
Fitment also affects practical restoration results. A tire that is correct in style but mismatched to the wheel can create avoidable issues with seating, clearance, or road behavior. Before finishing the car for driving or show use, confirm wheel diameter, inspect rim condition, and choose the sidewall presentation that best matches the restoration’s intended character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1951 Bristol 402?
Yes. Even though the 1951 Bristol 402 uses a straightforward 550-16 fitment, later changes can alter what actually works on the car. Aftermarket wheels, brake conversions, suspension work, or body repairs may affect rim dimensions, steering clearance, or the space available around the tire.
A collector car should be measured as it sits today rather than assumed to retain every original specification. Confirm wheel diameter and width first, then check clearance at full steering lock and normal ride height. That is especially important if the Bristol has been restored in stages or passed through several owners over the decades.
What should I inspect before driving a 1951 Bristol 402 on new tires?
Before driving a 1951 Bristol 402 on new tires, inspect the wheels for corrosion, dents, cracks, and bead-seat condition, then confirm that each rim matches the intended 16-inch fitment. It also makes sense to check valve stems, mounting quality, and whether the tires are inflated appropriately for the setup being used.
The car itself deserves equal attention. Look over suspension bushings, steering play, brake function, and any signs of rubbing once the new 550-16 tires are mounted. A short local test drive is a smart way to confirm tracking, clearance, and general behavior before asking an older Bristol to handle sustained road mileage.
How should 550-16 tires on a collector 1951 Bristol 402 be maintained?
Collector-car tires such as 550-16 bias-ply tires on a 1951 Bristol 402 should be inspected regularly for cracking, flat spotting, bulges, cuts, uneven wear, and slow air loss. Because many collector cars are driven infrequently, age and storage conditions can matter just as much as tread depth.
Keep the tires clean, maintain stable pressure, and store the car away from prolonged sunlight, excess moisture, and ozone sources such as electric motors or battery chargers. Moving the car periodically can help reduce flat spotting during long storage periods, and any tire showing visible deterioration should be evaluated before road use resumes.
