1956 Arnolt-Bristol Tire Fitment Guide

1956 Arnolt-Bristol vehicles covered here use one tire size: 550-16. That size applies to the 1956 Arnolt-Bristol MKII and mounts on a 16-inch wheel. Where rim-width guidance is provided, 550-16 products list a compatible range of 3.25 to 4.00 inches, although that range should still be checked against the exact wheel on the car.

Because there is only one fitment size in this range, most buyers are not choosing between alternate dimensions. The more useful comparison is between blackwall and wide whitewall versions, along with brand preference and any load or speed markings on the specific tire you select. Confirm the wheel diameter and actual wheel width before ordering, especially on a hand-built or long-restored car where wheels may have been changed over time.

On a 1956 Arnolt-Bristol, 550-16 is a numeric bias-ply tire size. The 5.50 figure is the nominal section width expressed in inches, and the 16 is the wheel diameter in inches. Unlike a modern metric radial size, it does not spell out an aspect ratio, and the bias-ply construction is part of the period-correct sizing system rather than shown with an R in the code.

That matters because a 550-16 should be understood as an older-style fitment standard, not translated loosely into a modern metric size without careful comparison. Buyers restoring an Arnolt-Bristol usually want the correct visual proportion and casing style as much as the basic dimensions. Keeping the original numeric format also helps preserve the proper stance and vintage appearance that suit a mid-1950s specialty sports car.

The 1956 Arnolt-Bristol model covered here, the MKII, uses 550-16. Within this year-and-make range, there is no second size competing with it, so there is no model-to-model fitment split to sort out. The shared wheel diameter for the fitment is 16 inches.

That simplifies the search process because the first question is usually just whether your car is an MKII on correct-spec wheels. After that, the decision moves to brand, sidewall style, and the look you want the finished car to present. On a low-production car like an Arnolt-Bristol, it is still wise to compare the actual tire on the car and confirm wheel dimensions before making a final choice.

1956 Arnolt-Bristol tires in 550-16 are available in both blackwall and wide whitewall form. Blackwall choices appear from Excelsior and Avon, while wide whitewall choices appear from BFGoodrich and Firestone. All of them stay within the correct-era bias-ply construction family for a mid-1950s sports car.

Sidewall style changes the visual character of the car more than the fitment itself. A blackwall usually gives a more restrained sports-car presentation, while a wide whitewall creates a stronger period styling statement that can suit a show-focused restoration. The right answer depends on how your particular Arnolt-Bristol is being restored and the look you want when the car is viewed as a whole.

Four brands appear in the 550-16 fitment for 1956 Arnolt-Bristol vehicles: Excelsior, Avon, BFGoodrich, and Firestone. Each is offered as a bias-ply tire in the correct basic size, with sidewall style differences separating some of the choices. Avon appears here in a Tourist Crossply line, while BFGoodrich and Firestone are represented with wide whitewall offerings.

Brand choice often comes down to the combination of appearance, heritage, and the exact specifications shown on the tire. Some owners will gravitate toward a simpler blackwall for a competition-minded look, while others may prefer a named American classic tire line with a whitewall for a more stylized restoration. Comparing the sidewall treatment and any stated load or speed marking is usually more useful than treating all 550-16 tires as interchangeable in character.

For the 1956 Arnolt-Bristol, both the Firestone Classic Bias Ply and BFGoodrich Silvertown Classic Bias Ply appear in 550-16 with wide whitewall styling and bias-ply construction. The Firestone listing carries a published maximum load of 840 pounds at 32 psi and a listed weight of 19 pounds, while the BFGoodrich listing is also a 550-16 wide whitewall but does not present the same pressure-and-load figure in the available details.

That means the comparison is less about basic fitment and more about which presentation and published specifications matter to you. If you want to compare beyond appearance, review the exact sidewall marking and any stated load information on the tire you are considering. On a specialty car such as an Arnolt-Bristol, those small differences can matter when you are aiming for a particular restoration style or trying to match a set already on the car.

Published rim-width guidance for 1956 Arnolt-Bristol 550-16 tires includes a 3.25 to 4.00 inch range on products where that information is shown. The wheel diameter is 16 inches, so both diameter and width need to be checked together rather than assuming any 16-inch wheel is automatically correct. Bias-ply tires are more sensitive to proper wheel match than many owners realize.

The practical step is to measure or verify the wheel actually fitted to the car before making a final tire decision. Rare cars are often restored over decades, and replacement wheels do not always match original dimensions. Staying within the stated rim-width range where it is provided helps preserve the intended profile and avoids forcing the casing onto a wheel that is too narrow or too wide.

The 1956 Arnolt-Bristol 550-16 products shown here do not include a TT or TL marking in the size descriptions, so tube requirement is something to confirm against the exact tire and wheel combination rather than assume from size alone. On collector cars of this era, tube use can depend on both the tire's construction details and whether the wheel itself is intended for tube-type service.

The safest approach is to inspect the wheel design and check the sidewall markings on the exact tire you plan to use. If the car retains original-style wheels, many restorers also inspect valve stems, wheel condition, and bead-seat integrity at the same time. That extra step is especially worthwhile on a low-volume 1950s sports car where wheel history may not be straightforward.

A 1956 Arnolt-Bristol should be stored out of direct sunlight, away from ozone-producing equipment such as electric motors and compressors, and in a dry, stable environment. Bias-ply tires can develop temporary flat-spotting more readily during long static storage, so periodic movement of the car or the use of stands in long-term storage can help reduce casing stress. Proper inflation during storage also matters.

Collector cars benefit from a storage routine that protects both the tires and the wheels at the same time. Clean the tires before putting the car away, avoid petroleum-based dressings, and do not let the car sit for months on soft or underinflated tires. If the Arnolt-Bristol is stored for an extended season, a short inspection and pressure check before the next drive should be part of waking the car back up.

Tires on a 1956 Arnolt-Bristol should be judged more by age and condition than by mileage. A good rule for a collector car is to begin careful evaluation around five to seven years of age and to treat about ten years as a point where replacement deserves serious consideration, even if the tread still looks usable. The DOT date code on the tire helps establish age.

That timeline reflects the reality of low-use vintage cars, which often age their tires out before wearing them out. Heat cycling, sunlight, storage conditions, and long periods of inactivity all affect the casing. If the car is driven infrequently, keeping a written record of installation dates and regular inspections is often more useful than trying to estimate service life from miles alone.

Tires on a 1956 Arnolt-Bristol should be inspected before every drive and again before any longer outing or tour. Look for sidewall cracking, cuts, tread separation, bulges, uneven wear, and signs that the tire is not holding pressure correctly. Because collector cars may sit for stretches, a tire that looked fine last season can still need attention before the next road use.

A quick pre-drive check takes only a few minutes and can prevent trouble that spoils a drive or damages a rare car. Include the spare in the same routine, and inspect valve stems and wheel condition while you are there. If the car uses tubes or older wheels, that inspection habit becomes even more valuable because slow leaks and age-related issues are easier to catch early.

A 1956 Arnolt-Bristol MKII would have been fitted in the bias-ply era, and the 550-16 size aligns with that period construction and sizing practice. The available fitment here stays within that traditional bias-ply format rather than shifting to a later radial-metric system. Original-equipment brand choice could vary by market, distributor, or restoration history, so the most reliable benchmark is the correct size, construction type, and period presentation.

For an owner pursuing a factory-style restoration, getting those fundamentals right usually matters more than chasing a brand name without supporting evidence. Sidewall treatment can also influence authenticity depending on how the car is being restored and judged. If you are preparing a serious concours car, it is wise to compare surviving photos, period literature, and Arnolt-Bristol club knowledge before making the final call.

Correct tire fitment does matter when showing a 1956 Arnolt-Bristol, especially on a rare car where overall presentation is closely scrutinized. Judges and knowledgeable enthusiasts typically notice whether the size, construction type, and sidewall style suit the period. A mid-1950s specialty sports car wearing the right 550-16 bias-ply format will usually look more convincing than the same car on an obviously later-style tire.

The practical issue is deciding what standard you are building toward. A local show may reward general presentation, while marque-oriented or high-level judging can be more sensitive to sidewall details and the overall stance of the car. If your Arnolt-Bristol will be judged, check event standards and compare with accepted restorations so your tire choice supports the rest of the car rather than distracting from it.

For the 1956 Arnolt-Bristol, the difference between blackwall and wide whitewall tires is primarily visual rather than dimensional, since both appear in the same 550-16 bias-ply size. Blackwall examples are offered by Excelsior and Avon, while wide whitewall versions are offered by BFGoodrich and Firestone. All preserve the correct basic period construction, but they create very different finished looks.

A blackwall usually suits an owner who wants a more restrained sporting appearance, which can feel natural on an Arnolt-Bristol's purposeful lines. A wide whitewall makes a stronger styling statement and may better match a restoration that leans into 1950s visual drama. The best choice depends on how original your car is intended to look and whether your target audience is general enthusiasts or marque-savvy judges.

1956 Arnolt-Bristol tires in the listed 550-16 fitment are bias-ply tires, and one Avon example in this size carries an 80L marking, indicating an 80 mph speed ceiling for that tire. Highway use is possible when the tires are in sound condition, correctly inflated, and matched to a mechanically healthy car. On a 1950s sports car, the vehicle's braking, steering, suspension, and alignment condition are often just as important as the tire itself.

The key is to treat highway driving as a whole-vehicle decision rather than a tire-size question alone. Fresh, properly fitted tires help, but so do realistic speeds, proper pressures, and attention to how the car feels once warmed up. If the Arnolt-Bristol has been sitting or recently returned to service, a shorter shakedown drive is smarter than assuming a rare collector car is ready for sustained high-speed use immediately.

Inflation pressure for 1956 Arnolt-Bristol tires should be set by the vehicle's factory recommendation and then checked against the specific tire's published rating information. In the 550-16 fitment shown here, one Firestone tire lists a maximum load of 840 pounds at 32 psi. That figure is a tire rating point, not a blanket instruction to run every 550-16 tire on every Arnolt-Bristol at the same pressure.

Use the owner's manual or accepted marque guidance for the starting pressure, then verify that the chosen tire's load-and-pressure limits support the intended use. Bias-ply tires can feel and wear differently when overinflated or underinflated, so small deviations matter. If you change tire brand or construction details within the same size, revisit pressures rather than assuming the previous setting is automatically ideal.

Before taking a 1956 Arnolt-Bristol on a longer drive, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation, and check that the spare is usable as well. Look closely at the valve stems, and confirm that the wheels and lug hardware are in good condition. A longer outing in a low-production 1950s sports car should always start with a careful walkaround.

Tires are only one part of the pre-drive checklist, but they are one of the easiest places to catch trouble early. Add a check of brakes, steering response, fluid levels, and cooling health before committing to distance. If the car has not been driven recently, letting it prove itself on shorter local runs first is the best way to build confidence without putting unnecessary stress on a rare Arnolt-Bristol.
