The 1955 Bristol 404 sits in a distinctive corner of postwar British motoring, blending Bristol’s aircraft-influenced engineering character with compact grand touring style. It is the kind of collector car where tire choice affects both appearance and the way the car presents on the road. Fitment for the 1955 Bristol 404 spans 16-inch tires in both bias-ply and radial form, with size differences tied to early and late saloon configurations. That gives owners a real choice between traditional numeric bias-ply sizing and a Euro-metric radial format, along with different sidewall treatments and tire series in the bias-ply range. The right selection starts with the exact saloon version, then balances road use, visual authenticity, and wheel compatibility.
Which Tire Size Is Right for The 1955 Bristol 404
The 1955 Bristol 404 uses three primary tire sizes, all on 16-inch rims, and the correct choice depends on the exact saloon version. Early cars can use either 175R16 radial or 600-16 bias-ply, while late saloons use 550-16 bias-ply. Before comparing brands or sidewall styles, confirm whether the car is an early or late saloon and whether it is currently set up for radial or bias-ply construction.
175R16 is a Euro-metric radial size in which 175 identifies the nominal section width in millimeters, R indicates radial construction, and 16 is the rim diameter in inches. On the 1955 Bristol 404, this size applies to the early saloon configuration and represents the radial option within the covered fitments. Its sizing format differs from the car’s numeric bias-ply alternatives, so the practical decision is less about decoding the number and more about confirming that the car’s wheels, clearances, and overall setup are appropriate for a radial-equipped early car.
600-16 is a numeric bias-ply size, with the leading number representing an approximate 6.00-inch nominal section width and the 16 identifying the wheel diameter. On the 1955 Bristol 404, this bias-ply fitment belongs to the early saloon and opens up the broadest range of traditional-looking tire choices. Available options include blackwall, wide whitewall, and double-whitewall styles from brands such as BFGoodrich, Firestone, Coker Classic, Goodyear, Avon, Excelsior, Ford Script, STA, and Camac. It is the right size to evaluate when the goal is a vintage construction and a more restoration-oriented visual presentation.
550-16 is also a numeric bias-ply size, but with a narrower nominal 5.50-inch section width and the same 16-inch rim diameter. For the 1955 Bristol 404, this size belongs to the late saloon configuration rather than the earlier cars. Product choices include blackwall and wide whitewall tires from brands such as Excelsior, Avon, BFGoodrich, and Firestone, with series that lean toward traditional collector-car use. It is the size to focus on when a late saloon is being kept in its bias-ply format and the owner wants to compare appearance as carefully as fitment.
Sub-model fitment matters on the 1955 Bristol 404 because the early and late saloon versions do not use the same tire setup. Identifying the exact saloon configuration comes first, since an early car may be fitted with either radial or bias-ply construction while the late saloon uses a different bias-ply size.

1955 Bristol 404 (Early) Saloon
The 1955 Bristol 404 (Early) Saloon uses either 175R16 radial or 600-16 bias-ply tires on 16-inch rims. That makes construction choice part of the decision, so it is important to confirm whether the car is being kept in a traditional bias-ply presentation or evaluated around an established radial setup.
The 1955 Bristol 404 (Late) Saloon uses the narrower 550-16 bias-ply size on a 16-inch rim. Tire selection here is more straightforward, with the main decision centered on blackwall versus whitewall appearance and comparing the available bias-ply brands and series.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners of a 1955 Bristol 404 usually need to sort out early versus late saloon fitment first, then decide between numeric bias-ply and radial sizing where applicable. These FAQs cover tire size, rim fitment, construction choice, appearance, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 1955 Bristol 404?
The 1955 Bristol 404 uses three primary tire sizes: 175R16, 600-16, and 550-16. The early saloon uses either 175R16 radial or 600-16 bias-ply, while the late saloon uses 550-16 bias-ply. All three fitments are built around a 16-inch rim diameter.
The first step is confirming whether the car is an early or late saloon, since that determines which size family belongs on the car. After that, check the actual wheel setup on the vehicle, especially if it has been restored, re-wheeled, or converted between constructions at some point in its life.
What size rim does a 1955 Bristol 404 use?
The 1955 Bristol 404 uses 16-inch rims across its covered tire fitments. That remains true whether the car is fitted with 175R16 radial, 600-16 bias-ply, or 550-16 bias-ply tires. The diameter stays consistent even though the tire sizes and constructions vary by saloon version.
Rim diameter is only part of the fitment picture, so wheel width should still be checked before choosing among available products. That matters most when comparing different bias-ply lines or confirming a car that may no longer be wearing its original wheel set after years of collector ownership or restoration work.
Why does the 1955 Bristol 404 have more than one tire size?
More than one tire size appears on the 1955 Bristol 404 because fitment changes between the early and late saloon versions, and the early car also spans both radial and bias-ply construction. The early saloon uses 175R16 or 600-16, while the late saloon uses 550-16.
That means tire selection is not just a matter of choosing any 16-inch tire that looks close. The exact saloon version, the wheel dimensions on the car today, and the construction you intend to keep all matter before settling on a specific tire line, sidewall treatment, or period-style appearance.
Choosing the Right Tire
What should I consider when choosing a 600-16 tire for a 1955 Bristol 404?
A 600-16 tire for a 1955 Bristol 404 should first be matched to an early saloon that uses the numeric bias-ply fitment. After size is confirmed, the meaningful differences are tire series, brand, sidewall style, and rim-width specification, since 600-16 appears in blackwall, wide whitewall, and double-whitewall forms.
Choice within that size depends on how the car is used and how traditional you want it to look. A restoration-oriented owner may focus on visual presentation, while a road-use owner may spend more time comparing the tire’s intended category and wheel-width compatibility before making a final decision.
What sidewall styles are available for 1955 Bristol 404 tires?
The 1955 Bristol 404’s applicable bias-ply tire offerings include blackwall, wide whitewall, and double-whitewall styles, depending on the size and series selected. The broadest sidewall variety appears in 600-16, while 550-16 also includes both blackwall and wide whitewall options for late saloon fitment.
Sidewall style changes the car’s visual character more than many owners expect, especially on a compact 1950s British saloon. Keeping the correct tire size and construction family comes first, then the sidewall treatment can be used to lean the car toward a cleaner touring look or a more decorative period-style presentation.
What brands offer tires for the 1955 Bristol 404?
Applicable 1955 Bristol 404 bias-ply products include brands such as BFGoodrich, Firestone, Coker Classic, Goodyear, Avon, Excelsior, Ford Script, STA, and Camac, depending on tire size. Brand availability is much broader in 600-16 than in 550-16, so the exact saloon fitment affects how many options can be compared.
Brand choice should follow size, construction, and wheel compatibility rather than the other way around. Once those basics are settled, comparing brand offerings becomes useful for narrowing the visual style, tire series character, and sidewall treatment that best suits the way the Bristol is being maintained or presented.
Restoration & Appearance
Which tire should I choose for a period-style 1955 Bristol 404?
A period-style 1955 Bristol 404 tire choice starts with the correct primary fitment for the exact saloon version. Early cars may be evaluated around 600-16 bias-ply for a traditional presentation, while late saloons use 550-16 bias-ply. Those numeric bias-ply sizes align most naturally with the car’s mid-1950s character.
After the size is confirmed, the appearance decision usually comes down to blackwall, wide whitewall, or, in some 600-16 offerings, double-whitewall styling. Owners seeking exact historical accuracy should compare the car against marque references or restoration records, since period-style and exact as-delivered appearance are not always the same thing.
How does tire construction affect the appearance of a restored 1955 Bristol 404?
Tire construction changes the look of a restored 1955 Bristol 404 because bias-ply and radial tires present differently even when both use the same 16-inch wheel diameter. On this car, the numeric 600-16 and 550-16 bias-ply options deliver the most traditional vintage sizing language, while 175R16 introduces a later radial format on the early saloon.
That difference matters most when the goal is a restoration-oriented presentation rather than simple road service. Owners preserving a more original visual mood often start with the correct bias-ply size for their sub-model, then refine the final look through sidewall treatment instead of assuming construction has no effect on appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1955 Bristol 404?
Modifications can absolutely affect tire fitment on a 1955 Bristol 404, even though all covered sizes use a 16-inch rim diameter. Wheel-width changes, different offsets, suspension alterations, or body and brake updates can influence how a 175R16, 600-16, or 550-16 tire sits in the car and clears surrounding components.
A collector car that has passed through multiple owners may no longer match its earlier wheel or suspension setup, so visual confirmation matters. Check the wheel dimensions actually on the car, then inspect steering clearance, fender space, and stance before assuming the original fitment path still matches the car as it sits today.
What should I inspect before driving a 1955 Bristol 404 on new tires?
Before driving a 1955 Bristol 404 on new tires, inspect wheel condition, confirm the tire size matches the correct saloon fitment, and make sure the tires seat properly on the rims. It is also wise to check for adequate clearance at full steering lock and through suspension movement before any meaningful road mileage is added.
A short initial drive should be followed by another visual check for rubbing, uneven stance, or unexpected air loss. Collector cars benefit from extra caution because aged suspension parts, old wheels, and long storage intervals can reveal problems only after the car is back in motion under normal road load.
How should 1955 Bristol 404 tires be maintained on a collector car?
Tires on a collector-grade 1955 Bristol 404 should be maintained with regular pressure checks, periodic visual inspection, and careful storage habits. Look for sidewall cracking, cuts, bulges, uneven wear, and slow air loss, especially on a car that sees infrequent use and may spend long stretches parked between drives.
Good storage conditions help preserve both appearance and serviceability, so keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources when possible. Even a lightly used Bristol should have its tires inspected routinely, because age and storage conditions can matter just as much as tread depth on a vintage vehicle.
