1957 Arnolt-Bristol Tire Fitment Guide

1957 Arnolt-Bristol vehicles use one tire size: 550-16. Within this year and make, that size applies to the MKII and mounts on a 16-inch wheel. Rim width guidance appears on some 550-16 products at 3.25 to 4.00 inches, which is the wheel-width range to compare against your actual wheels when narrowing down a tire choice.

That makes fitment relatively simple compared with year-make pages that split across multiple sizes or wheel diameters. The important step is confirming that your car is in fact a 1957 Arnolt-Bristol MKII and then checking the wheel itself before choosing among the available blackwall and whitewall bias-ply options in 550-16.

On a 1957 Arnolt-Bristol, 550-16 is a traditional numeric bias-ply size. The 5.50 portion refers to the tire's nominal section width in inches, while the 16 identifies the wheel diameter in inches. Unlike modern metric radial sizing, it does not include a stated aspect ratio in the code, and the construction here is bias-ply rather than radial.

That matters because a 1950s numeric bias-ply designation describes a tire family with period-correct proportions and road feel, not a modern high-information metric package. If your goal is to keep the Arnolt-Bristol visually and dynamically in its proper era, understanding that older size language helps you avoid comparing it too literally to later radial conventions.

Yes. For 1957 Arnolt-Bristol applications covered here, the MKII uses 550-16, so there is no year-and-make split into multiple tire sizes. The shared fitment also means every product option for this year revolves around the same 16-inch wheel diameter and the same basic bias-ply sizing convention.

That simplifies the shopping process because the question is not which diameter or alternate size belongs to a different model. Instead, your attention can go toward brand preference, blackwall versus wide whitewall appearance, and whether the tire's intended rim-width range matches the wheels currently on the car.

1957 Arnolt-Bristol tires in 550-16 are offered in both blackwall and wide whitewall form. Blackwall options include Excelsior and Avon, while wide whitewall options appear from BFGoodrich and Firestone. All are bias-ply tires, so the sidewall choice changes the visual presentation more than the basic construction style.

For a sporting British-Italian specialty car like the Arnolt-Bristol, many owners lean toward blackwalls for a cleaner, more purposeful look that suits the car's roadster character. Wide whitewalls can still be attractive if the restoration is styled around a more formal 1950s American visual cue, but concours expectations are best checked against marque-specific references and event standards.

Four brands are represented for 1957 Arnolt-Bristol fitment in 550-16: Excelsior, Avon, BFGoodrich, and Firestone. Each of those offerings is a bias-ply tire built around the same basic size, but they differ in sidewall presentation and, in some cases, in the load information published with the tire.

That gives Arnolt-Bristol owners a useful spread of choices without changing away from the correct period construction. Avon often appeals to buyers who like a brand with long-standing British-market credibility, while BFGoodrich and Firestone whitewall options may suit owners aiming for a certain 1950s visual treatment. The final pick usually comes down to appearance, published specifications, and how the car will be used.

The Avon Tourist 550-16 80L and Firestone 2.50 Inch Whitewall 550-16 are both bias-ply tires for the 1957 Arnolt-Bristol, but they differ in presentation and listed specifications. Avon is a blackwall tire with a published maximum load capacity of 992 pounds, while the Firestone is a wide whitewall with a published 840-pound load figure at 32 psi. The Firestone also lists a rim-width range of 3.25 to 4.00 inches.

That makes the choice fairly clear for many owners. Avon suits a more understated sports-car appearance, while the Firestone changes the car's period look more dramatically through its whitewall styling. Before settling on either one, compare your wheel width to the tire's published rim guidance and decide whether the finished car should read as sporting and restrained or more visibly stylized.

Rim width guidance is published on some 1957 Arnolt-Bristol 550-16 tires at 3.25 to 4.00 inches. That range appears on both the Excelsior and Firestone versions of the size, and it is the most direct wheel-width reference available within the current 550-16 product selection. All of the fitments here use a 16-inch rim diameter.

The practical takeaway is to measure the wheel on the car rather than relying on assumption, especially with a limited-production specialty vehicle that may have been restored or modified over the years. If your wheel falls within that 3.25-to-4.00-inch range, you are working from a strong starting point for those products. If it does not, compare the wheel carefully against the tire you are considering before moving forward.

The available 1957 Arnolt-Bristol 550-16 products are presented as traditional bias-ply tires, but the current markings shown for this size do not split the lineup into clearly labeled tube-type and tubeless variants. On a car of this era, tube use is often tied as much to wheel design and wheel condition as to the tire itself, especially if the original wheels are being retained.

That means the right approach is to inspect the actual wheels and confirm the sidewall markings of the specific tire you intend to use. If the car still wears original-style wheels, many owners also have the wheels checked by a knowledgeable restoration or wheel specialist before mounting new tires so the final setup matches both the product and the hardware.

A 1957 Arnolt-Bristol should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Bias-ply tires also benefit from being kept at proper inflation during storage, because they are more prone than radials to taking a temporary flat spot if the car sits in one position for long periods.

If the car will be parked for months rather than weeks, move it periodically or support it in a way that reduces constant loading on one patch of tread. Clean, dry floors and moderate indoor temperatures help as well. Those simple storage habits preserve both the tire casing and the way the Arnolt-Bristol feels when it goes back on the road.

On a collector car like a 1957 Arnolt-Bristol, tire age usually matters more than mileage. A sensible rule is to begin inspecting more critically once tires reach the five-to-seven-year range and to treat around ten years from the DOT date code as a point where replacement deserves serious consideration, even if tread depth still looks acceptable.

That guideline is especially relevant for low-use sports cars that spend much of their life parked, trailered, or driven only to events. Rubber hardens and ages whether or not the miles accumulate. If the car is showing sidewall cracking, persistent flat-spotting, pressure loss, or any visible distortion, those signs matter at least as much as the odometer when deciding whether to replace the tires.

Tires on a 1957 Arnolt-Bristol should be inspected before every drive and again before any longer outing. Look for sidewall cracking, tread separation, bulges, cuts, embedded debris, uneven wear, and any sign that the tire is no longer holding pressure consistently. Because this is a 1950s collector car, the spare deserves the same attention as the four road tires.

A quick visual check is not enough if the car has been parked for a while. Run your hand around the tread and sidewall, verify inflation with a gauge, and inspect valve stems as part of the routine. Catching a storage-related issue in the garage is far better than finding it after the car is warmed up and miles from home.

A 1957 Arnolt-Bristol MKII belongs to an era when bias-ply tires were the expected original construction type, and the size used here is 550-16. That aligns with the period character of the car and with the proportions enthusiasts expect to see on a mid-1950s specialty sports car. No original-equipment brand should be assumed solely from modern replacement choices.

For most restorations, the key points are getting the size, the bias-ply construction, and the sidewall look in harmony with the car's intended presentation. If you are pursuing high-level authenticity, especially for judged events, it is wise to compare your car against period photos, factory literature, and Arnolt-Bristol marque sources because market-specific or owner-delivery differences can influence what is considered most correct.

Yes, correct tire fitment matters on a 1957 Arnolt-Bristol because judges and knowledgeable enthusiasts often notice tire size, construction type, and sidewall appearance immediately. A 550-16 bias-ply tire keeps the car within the right visual and historical vocabulary for the period, while an obviously modern alternative can change the stance and presentation enough to draw scrutiny.

The details that matter most depend on the event. Some shows emphasize broad period correctness, while others look more closely at market presentation and restoration philosophy. Blackwall versus whitewall can also affect how authentic the finished car appears, so event standards and marque-club guidance should shape the final choice if the car is being prepared for serious judging rather than casual display.

Excelsior and BFGoodrich both offer 550-16 bias-ply tires for the 1957 Arnolt-Bristol, but the most visible difference is sidewall presentation. The Excelsior version is a blackwall, while the BFGoodrich offering uses a 2.25-inch wide whitewall. Both preserve the era-correct bias-ply construction and the proper 16-inch fitment for the MKII.

That makes the choice especially important for restoration tone. Excelsior will usually read as more restrained and sporting on an Arnolt-Bristol, while the BFGoodrich creates a more stylized 1950s visual statement. Neither changes the basic size or period construction, so the decision is largely about whether the finished car should look closer to a purposeful road machine or a more formal period presentation.

1957 Arnolt-Bristol tires in the available 550-16 range can be suitable for highway use when they are new, properly mounted, correctly inflated, and matched to sound wheels. One current 550-16 option, the Avon Tourist 80L, carries an L speed rating, which corresponds to 75 mph. The broader safety picture on a 1957 specialty sports car also depends heavily on the car's brakes, steering, suspension, and overall mechanical condition.

That means the tire itself is only one part of highway readiness. A freshly restored or well-maintained Arnolt-Bristol on proper bias-ply tires can be enjoyed responsibly, but it should still be driven within the limits of its era and condition. Before regular highway use, make sure the alignment, wheel balance, suspension bushings, and braking system are all up to the same standard as the tires.

Inflation pressure for 1957 Arnolt-Bristol tires should be set with two references in mind: the vehicle's original recommended pressure and the reproduction tire's own published limits. Within the current 550-16 choices, one Firestone tire lists a load figure of 840 pounds at 32 psi. That figure belongs to that specific product and should not be transferred automatically to every 550-16 tire.

The safest approach is to start with the owner's or factory specification for the car, then compare that against the tire manufacturer's published guidance for the exact tire you are using. Pressures that are too high can make a light sports car feel skittish, while pressures that are too low can affect wear and stability. Check inflation cold and recheck it regularly on a collector car that is driven infrequently.

Before taking a 1957 Arnolt-Bristol on a longer drive, inspect each tire for cracking, cuts, bulges, uneven wear, and any sign of separation or age-related hardening. Verify cold inflation pressure, look closely at the valve stems, and make sure the spare is serviceable. On a vintage car, it is also smart to check wheel fasteners, brake response, fluid levels, and whether the car tracks straight without unusual vibration.

A specialty car like the Arnolt-Bristol rewards thorough pre-drive preparation because even a short touring route can expose weak points quickly. If the tires have been sitting for long periods, take a short local drive first to feel for flat spots or pulling before committing to distance. That brief shakedown can reveal problems while you are still close to tools, air, and familiar roads.
