The 1966 Bristol 408 sits in a distinctive corner of British grand touring, blending hand-built exclusivity with understated performance and long-distance road manners. Owners are often balancing originality, drivability, and the car’s refined period character rather than chasing a one-size-fits-all tire answer. For this model, the key fitment decision centers on two 16-inch tire paths: a 600-16 bias-ply choice or a 175R16 radial. Available tires span traditional blackwalls along with whitewall treatments in the bias-ply size, so the decision is as much about presentation and driving intent as it is about size. Wheel condition, construction choice, and the car’s actual setup should all be confirmed before road use.
Which Tire Size Is Right for The 1966 Bristol 408
The 1966 Bristol 408 uses two primary tire sizes, and both fit a 16-inch rim. The important distinction is construction rather than wheel diameter: 600-16 is a bias-ply fitment, while 175R16 is a radial fitment. Since the Bristol 408 Base is associated with both sizes, the real choice is whether to keep a traditional bias-ply presentation or move toward a radial setup after confirming wheel compatibility and the car’s actual configuration.
The 175R16 size uses a metric section width of 175 millimeters, radial construction, and a 16-inch rim diameter. On a 1966 Bristol 408, this size represents the radial side of the fitment picture and is typically the choice for owners evaluating a more modern construction within the correct rim diameter. The size format is familiar to later European vehicles, even though it still suits a classic touring car context. This is the size to examine when the goal is radial construction on the Bristol’s 16-inch wheels without moving into an older numeric bias-ply designation.
The 600-16 size is a vintage numeric bias-ply designation in which the leading number refers to nominal section width in inches and the final number identifies a 16-inch rim. For the 1966 Bristol 408, it preserves a traditional tire format and opens up the broadest range of visible style choices. Available options include blackwall, wide whitewall, and double-whitewall tires from brands such as BFGoodrich, Firestone, Goodyear, Coker Classic, Avon, Excelsior, Lester, STA, Camac, and Ford Script across several series. This size is the one to study closely when period-style appearance matters as much as basic fitment.
Fitment is straightforward here because the covered sub-model shares the same two 16-inch tire paths. Checking the exact sub-model still matters, but the main decision on a 1966 Bristol 408 is whether to use the radial 175R16 or the bias-ply 600-16.

Tire Size & Fitment
What tire size fits a 1966 Bristol 408?
The 1966 Bristol 408 uses two primary tire sizes: 175R16 in radial construction and 600-16 in bias-ply construction. Both sizes are associated with the Bristol 408 Base and both use a 16-inch rim, so the fitment question is not just about diameter but also about which tire construction the car is set up to use.
That means the next step is confirming the wheel and vehicle setup before choosing between the two. A buyer comparing these sizes should look at wheel condition, wheel width where known, tire construction preference, and the car’s intended use, especially if originality of appearance matters as much as road manners.
What size rim does a 1966 Bristol 408 use?
The 1966 Bristol 408 uses a 16-inch rim with both of its associated tire sizes, 175R16 and 600-16. Even though the tire sizing formats are different, the wheel diameter remains the same, which simplifies the first stage of fitment compared with cars that used multiple rim diameters across trim levels.
Rim diameter is only part of the picture, so it is still worth checking the actual wheel on the car before ordering tires. Collector vehicles may have had wheel changes over the years, and a move between radial and bias-ply construction should also prompt a closer look at wheel width, clearance, and general wheel condition.
What does 600-16 mean on a 1966 Bristol 408?
A 600-16 is a vintage numeric bias-ply tire size. The 600 portion refers to a nominal section width of about 6.00 inches, while the 16 identifies the rim diameter in inches. On a 1966 Bristol 408, this size represents the traditional bias-ply fitment path rather than a modern metric radial format.
Understanding that older size code helps when comparing period-style tires, since many products in 600-16 differ more by series and sidewall appearance than by basic fitment. Once the size is confirmed, the more useful shopping questions become blackwall versus whitewall treatment, brand and series preference, and whether the car should stay bias-ply.
Bias-Ply & Radial Options
Is 600-16 a bias-ply or radial tire for the 1966 Bristol 408?
For the 1966 Bristol 408, 600-16 is a bias-ply tire size. It uses the older numeric sizing system and is tied to the traditional construction choice for this car, while 175R16 is the radial size associated with the same 16-inch rim diameter.
That distinction matters because choosing 600-16 is usually about preserving a more period-style tire format and appearance. Anyone moving away from it should compare the wheel setup and overall tire presentation carefully, since matching rim diameter alone does not make two different construction types automatically interchangeable in every real-world installation.
Should I use bias-ply or radial tires on a 1966 Bristol 408?
A 1966 Bristol 408 can be approached from either direction because both 600-16 bias-ply and 175R16 radial sizes are associated with the car. The choice comes down to what matters most for the car’s use: a more traditional vintage format and look, or a radial construction that aligns with a later tire design approach.
The practical decision should be made around the actual wheels on the car, how closely the owner wants to stay with a period-style presentation, and how the Bristol will be driven. A lightly used restoration may point one way, while a regularly driven grand tourer may point another, but the wheel and clearance checks still come first.
What should I check before converting my 1966 Bristol 408 from bias-ply to radial tires?
Start by confirming that the car is actually using the correct 16-inch wheels and that the intended radial size is 175R16. A conversion from 600-16 bias-ply to 175R16 radial should be treated as a deliberate fitment change rather than a simple same-diameter swap.
The most useful checks include wheel condition, wheel width, suspension condition, steering clearance, and fender clearance at full movement. It also helps to inspect whether the car has had wheel, brake, or suspension modifications over time, since an altered setup can change the way a radial tire sits and behaves on the vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 1966 Bristol 408?
The first choice for a 1966 Bristol 408 is size and construction: 175R16 radial or 600-16 bias-ply. After that, the important comparison points are the car’s intended use, the look you want, and whether the wheels currently on the car are appropriate for the tire being considered.
Within the 600-16 range, available options differ by brand, tire series, sidewall style, and some rim-width and load specifications. That gives restoration-minded owners more visual choice, while buyers focused on overall road use may start with the construction question first and narrow the product list from there.
What sidewall styles are available for 1966 Bristol 408 tires?
The broadest sidewall variety for the 1966 Bristol 408 appears in the 600-16 bias-ply size. That size is available in blackwall, wide whitewall, and double-whitewall forms, giving the owner a meaningful appearance choice without changing the basic 16-inch tire size.
Sidewall style mainly affects presentation, so the right choice depends on whether the car is being restored with a conservative touring look or with more visual emphasis. It is worth selecting the sidewall treatment after the correct size and construction are settled, since appearance should complement fitment rather than override it.
What brands offer tires for the 1966 Bristol 408?
The 600-16 tire size for the 1966 Bristol 408 is available from BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those products span several tire series, which is useful for buyers who want more than one visual or construction-era expression within the same basic size.
Brand choice should be approached as part of the overall tire decision, not as a stand-alone shortcut. Once the correct size and construction are settled, compare sidewall treatment, tire series, and any relevant rim-width or load details so the final choice suits both the Bristol’s appearance and its real road use.
Restoration & Appearance
Which tire should I choose for a period-style 1966 Bristol 408?
For a period-style presentation, the 600-16 bias-ply size is the natural starting point on a 1966 Bristol 408. It uses the vintage numeric format and offers the widest selection of traditional-looking tires, including blackwall, wide whitewall, and double-whitewall choices across several classic-style series.
That does not automatically make any one brand or sidewall treatment exactly right for every restored Bristol. Owners pursuing a highly exact appearance should compare surviving photos, marque references, and restoration documentation, while those seeking a broadly authentic road-going look can use the 600-16 bias-ply format as the foundation.
Does correct tire fitment matter for a 1966 Bristol 408 restoration?
Correct tire fitment matters because tires strongly influence the stance, visual balance, and overall character of a restored 1966 Bristol 408. On this car, the main restoration-related decision is whether to stay with the traditional 600-16 bias-ply format or use the 175R16 radial associated with the same 16-inch wheel diameter.
A tire that matches the car’s intended restoration direction usually looks more coherent than one chosen only by diameter. Even on a driver-oriented restoration, the details still matter, so it is wise to consider sidewall style, construction type, and how the selected tire complements the Bristol’s body lines and wheel presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1966 Bristol 408?
Yes, modifications can affect tire fitment on a 1966 Bristol 408 even when the tire size itself is correct. Changes to wheels, suspension height, steering components, brakes, or body clearance can all alter how a 175R16 or 600-16 tire sits on the car and how much space it has through full steering and suspension travel.
That is why a modified Bristol should be checked as an actual vehicle, not treated as a standard factory-spec example by assumption. A careful inspection of wheel diameter, wheel width, clearance at lock, and any signs of rubbing will help prevent choosing a tire that is correct on paper but awkward on the car.
What should I inspect before driving a 1966 Bristol 408 on new tires?
Before driving a 1966 Bristol 408 on new tires, inspect the wheels for condition, verify the tire size and construction chosen for the car, and make sure each tire is seated and inflated correctly. It also helps to check valve stems, lug hardware, and general clearance around suspension and bodywork.
A short initial road test is a smart follow-up, especially on a collector car that may not be driven often. Pay attention to air loss, vibration, rubbing, and steering feel, then recheck pressure and visible seating once the car has been driven briefly and returned to the garage for a second inspection.
How should tires on a collector 1966 Bristol 408 be maintained?
Tires on a collector 1966 Bristol 408 should be maintained with regular pressure checks, routine visual inspection, and storage habits that limit unnecessary aging. Even low-mileage tires deserve close attention because collector cars often spend long periods parked, which can hide problems until the car is driven again.
Look for cracking, bulges, cuts, flat spotting, and unexplained air loss, and inspect the tread and sidewalls before any longer outing. Keeping the car away from prolonged heat, direct sunlight, excess moisture, and ozone-producing equipment can also help preserve tire condition between drives and reduce surprises on the road.
