The 1955 Bristol 405 occupies an unusual place in postwar British motoring, combining Bristol’s aircraft-influenced engineering character with a refined four-door grand touring presence. Owners are often balancing authenticity, drivability, and the visual character that suits a hand-built car from this era. For this exact model, the primary fitment is a 500-16 bias-ply tire on a 16-inch rim, which keeps the tire discussion focused less on size choice and more on selecting the right style within that format. Available options lean toward a traditional blackwall presentation, so the key decisions center on intended use, period-style appearance, and confirming wheel condition before road service.
Which Tire Size Is Right for The 1955 Bristol 405
The 1955 Bristol 405 uses one primary tire size: 500-16. That means the main fitment question is straightforward, with a bias-ply tire on a 16-inch rim, including the covered Base sub-model. From there, the decision shifts to choosing the tire style that suits how the car will be used, while keeping construction, wheel compatibility, and overall presentation in mind.
A 500-16 is a numeric bias-ply size in which the 500 designates an approximate 5.00-inch nominal section width and the 16 identifies the wheel diameter in inches. On the 1955 Bristol 405, this keeps the car in its original-era sizing language and traditional bias-ply construction. The available 500-16 product uses a blackwall sidewall and Firestone’s Dirt Track series with a ribbed front design, giving the size a distinctly vintage presentation. This size is the right starting point when the goal is to stay with the proper period-style format and confirm the car’s wheels are still set up for a 16-inch bias-ply fitment.
Tire fitment is straightforward across the covered 1955 Bristol 405 sub-model lineup. The Base model uses the same primary tire size, so the focus stays on selecting the right tire within that fitment and verifying the wheel setup before installation.

Best 1955 Bristol 405 Tires for Sale
Available 500-16 options for the 1955 Bristol 405 focus on traditional bias-ply construction rather than a broad mix of fitments. The current choice centers on a Firestone blackwall tire in the Dirt Track series, so comparison points are mainly appearance, intended use, and wheel-width compatibility.
Common questions for the 1955 Bristol 405 usually center on the 500-16 tire size, 16-inch rim fitment, bias-ply construction, period-style appearance, and the checks worth making before returning a collector car to road use.
Tire Size & Fitment
What tire size fits a 1955 Bristol 405?
The 1955 Bristol 405 uses a 500-16 tire size. This is a numeric bias-ply fitment on a 16-inch rim, and the covered Base sub-model uses that same size, so there is no second primary size to sort through for this application.
That makes the size decision fairly direct, but it is still worth confirming that the car remains on the correct 16-inch wheels and has not been altered over the years. Many collector cars have seen wheel changes, long storage, or past replacement work, so the next step is checking wheel diameter, wheel width, and tire condition goals before choosing a replacement.
What size rim does a 1955 Bristol 405 use?
The 1955 Bristol 405 uses a 16-inch rim with its 500-16 tire size. The tire format itself confirms the wheel diameter, with the final number in 500-16 identifying a 16-inch wheel rather than a different rim size.
Wheel diameter should be confirmed on the car before any tire purchase, especially on a low-production collector vehicle that may have changed hands many times. Measuring the existing wheel and checking its width and condition helps prevent mismatches, and it is especially important when the car has old wheels, replacement rims, or uncertain restoration history.
Does the 1955 Bristol 405 Base use the same tire size?
Yes. The 1955 Bristol 405 Base uses the same 500-16 bias-ply tire size as the overall 1955 Bristol 405 fitment. That means the Base model does not introduce a second rim diameter or alternate primary size that would change the basic selection process.
Even with shared fitment, the practical check is still the car in front of you. A Bristol that has been restored, stored for long periods, or fitted with non-original wheels may need wheel measurements and clearance checks before replacement tires are chosen, particularly if the goal is to preserve a traditional look and proper road manners.
Choosing the Right Tire
What should I consider when choosing a 500-16 tire for a 1955 Bristol 405?
Start with the correct 500-16 size, bias-ply construction, and 16-inch wheel requirement. From there, the choice is less about multiple fitment sizes and more about selecting a tire whose style and intended use match the character of the Bristol, including sidewall appearance and overall vintage presentation.
It also helps to compare wheel-width compatibility, load specification, and how the car will actually be driven. A Bristol used for display, occasional touring, or more spirited vintage use may call for a different product emphasis, so the tire should suit both the wheel setup and the way the car will be put back on the road.
What sidewall styles are available for 1955 Bristol 405 tires?
The available 500-16 option for the 1955 Bristol 405 uses a blackwall sidewall. That gives the car a restrained, traditional tire presentation that suits many postwar British applications, especially when the goal is to keep the visual emphasis on the body and wheel design rather than decorative sidewall treatment.
Sidewall choice matters because it changes the car’s overall look even when the size stays the same. On a restoration-oriented Bristol, the right sidewall is usually the one that complements the intended period impression, so it is wise to compare archival photos, marque references, and the car’s finished style before settling on appearance alone.
What brands offer tires for the 1955 Bristol 405?
Firestone is represented in the available 500-16 fitment for the 1955 Bristol 405. The current option is part of the Firestone Dirt Track series, giving buyers a recognizable vintage brand choice within the correct size and bias-ply construction for this application.
Brand is only one part of the decision on a car like this. The more important comparison is how the tire’s series, sidewall style, wheel-width compatibility, and intended use line up with the Bristol’s setup, especially since a specialty vehicle with one primary size benefits from careful selection rather than broad brand shopping alone.
Restoration & Appearance
Which tire should I choose for a period-style 1955 Bristol 405?
A period-style approach starts with the 500-16 size and bias-ply construction, because that keeps the Bristol 405 in the sizing and construction format associated with its era. Staying within that fitment preserves the car’s traditional visual stance more effectively than treating it like a modern tire application.
Appearance details still deserve careful thought. The available blackwall presentation offers a restrained vintage look, but exact restoration decisions should be checked against marque-specific references, period photography, and the way the particular car is being finished. On a hand-built British car, subtle tire appearance choices can noticeably influence the completed result.
Does correct tire fitment matter for a 1955 Bristol 405 restoration?
Yes, correct tire fitment matters because tire size and construction strongly affect how a 1955 Bristol 405 sits, looks, and feels on the road. Using the proper 500-16 bias-ply format helps preserve the proportions and visual character expected from a mid-1950s Bristol sedan.
Fitment also matters mechanically, not just visually. A restoration should include confirming wheel diameter, wheel width, and overall wheel condition so the chosen tire suits the car’s actual setup. Even if the bodywork and trim are finished beautifully, an incorrect tire format can undermine both presentation and driving confidence.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1955 Bristol 405?
Yes. Even though the 1955 Bristol 405 uses a straightforward 500-16 fitment, modifications can still affect whether that size works as expected on the car. Wheel replacements, brake changes, altered suspension height, or body repairs can all influence clearances and the relationship between tire and wheel.
A Bristol that has lived through decades of repairs or restoration work deserves a hands-on check before new tires go on. Confirm the actual wheel diameter and width, look at inner and outer clearances, and make sure steering movement is unobstructed. That is especially important on specialty cars where past modifications may not be obvious at first glance.
What should I inspect before driving a 1955 Bristol 405 on new tires?
Before road use, inspect wheel condition, valve stems, tire seating, and inflation, then look over the rest of the car for issues that can affect how the new tires behave. Steering components, suspension wear, brake operation, and wheel-bearing condition are all worth checking on a collector Bristol.
The tires themselves should also be watched closely during the first drives. Recheck pressure after installation, pay attention to any rubbing or unusual vibration, and inspect for uneven contact or air loss once the car has been driven and parked again. Early inspection helps catch wheel or chassis issues before they become bigger problems.
How should 500-16 tires on a collector 1955 Bristol 405 be maintained?
Collector-car tires benefit from regular pressure checks, periodic visual inspection, and storage habits that limit deterioration. On a 1955 Bristol 405, 500-16 bias-ply tires should be watched for cracking, bulges, cuts, flat-spotting, and signs of age, especially if the car spends long stretches parked between outings.
Maintenance also includes protecting the tires from prolonged sun, heat, moisture, and ozone exposure in storage. Driving the car occasionally and moving it during extended storage can help avoid one spot carrying the load too long. A quick inspection before every outing is a smart habit on a seldom-driven postwar touring car.
