The 1932 Graham 56 Series came from a period when independent automakers competed on style, engineering character, and road presence during the heart of the pre-war era. Owners restoring or maintaining one today usually care as much about stance and presentation as they do about basic drivability. This model uses a 550-17 bias-ply tire on a 17-inch rim, which keeps the fitment firmly in traditional pre-war territory. Within that size, the main choices center on sidewall appearance, including blackwall, wide whitewall, and double-whitewall versions in BFGoodrich's Silvertown Classic Bias Ply line. The real decision is choosing the look and road character that best suits the car's restoration direction and wheel setup.
Which Tire Size Is Right for The 1932 Graham 56 Series
The 1932 Graham 56 Series uses one primary tire size: 550-17 in bias-ply construction on a 17-inch rim. The Base sub-model uses that same fitment, so the main decision is not between different primary sizes, but between sidewall styles and the kind of period-style presentation you want to maintain on the car.
The 550-17 size uses a vintage numeric bias-ply format in which the 550 indicates an approximate 5.50-inch nominal section width and the 17 identifies the wheel diameter in inches. For a 1932 Graham 56 Series, that means a traditional pre-war tire construction and visual profile rather than a modern radial format. Available choices in this size include BFGoodrich Silvertown Classic Bias Ply tires in blackwall, wide whitewall, and double-whitewall styles. That gives the owner room to match the tire's appearance to a more restrained driver-quality car or a more formal restoration-minded presentation.
Fitment is straightforward for the covered 1932 Graham 56 Series sub-model. The same primary tire size is used here, so checking the sub-model mainly helps confirm that the car still carries the expected wheel and tire setup.

1932 Graham 56 Series Base
The 1932 Graham 56 Series Base uses the same 550-17 bias-ply fitment as the broader model line. Tire selection therefore comes down to choosing the sidewall presentation that best suits the car while confirming that the wheels remain true 17-inch rims in the proper vintage configuration.
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.

Tire Size & Fitment
What tire size fits a 1932 Graham 56 Series?
The 1932 Graham 56 Series uses a 550-17 bias-ply tire. That is the primary fitment for this model, and the covered Base sub-model uses the same size, keeping tire selection fairly straightforward at the size level.
The next step is confirming that the car still has 17-inch wheels and has not been changed to a different wheel or tire package over the years. On a pre-war vehicle, wheel condition, bead-seat condition, and overall clearance are worth checking closely before installing new tires.
What size rim does a 1932 Graham 56 Series use?
The 1932 Graham 56 Series uses a 17-inch rim with its 550-17 tire size. That rim diameter is central to the fitment, since the tire size and wheel diameter work together and should be matched exactly.
A buyer should still verify the actual wheels on the car, especially if it has been restored, stored for many years, or modified by a previous owner. Pre-war wheels deserve extra attention for condition, trueness, and compatibility before mounting a fresh set of bias-ply tires.
Does the 1932 Graham 56 Series Base use the same tire size?
Yes. The 1932 Graham 56 Series Base uses the same 550-17 bias-ply tire size as the broader model fitment covered here. There is no separate primary size to sort through for that sub-model.
That consistency makes the size decision easier, but the car should still be checked for changes made over decades of use and restoration. Once the wheel diameter is confirmed, the buyer can focus more on sidewall style and the kind of period-style look that suits the car best.
Choosing the Right Tire
What should I consider when choosing a 550-17 tire for a 1932 Graham 56 Series?
Start with the correct primary fitment: 550-17 in bias-ply construction on a 17-inch rim. From there, the key choices are the tire's visual presentation and whether the car is being maintained as a preservation driver, a restoration-oriented vehicle, or a more formal show-minded example.
The available BFGoodrich Silvertown Classic Bias Ply options differ mainly by sidewall treatment rather than by a change in basic size or construction. Matching the tire's look to the vehicle matters on a pre-war car, but wheel condition, proper mounting, and overall road-readiness matter just as much.
What sidewall styles are available for 1932 Graham 56 Series tires?
The 1932 Graham 56 Series has 550-17 tire options in blackwall, wide whitewall, and double-whitewall form. All of those choices stay within the same bias-ply size, so the decision is mainly about appearance rather than changing the tire's basic fitment category.
A blackwall tends to give the car a more restrained and utilitarian presentation, while whitewall treatments create a more formal period-style look. Since sidewall style can strongly affect the visual balance of a pre-war car, it helps to consider the vehicle's paint, trim, and restoration theme before choosing.
What brands offer tires for the 1932 Graham 56 Series?
BFGoodrich offers 550-17 tires for the 1932 Graham 56 Series in the Silvertown Classic Bias Ply series. Within that brand and series, the visible variation comes from sidewall styling rather than a change to a different primary size.
That means the brand decision is simple, while the more important comparison becomes how each sidewall treatment suits the car's intended look. It is still worth confirming wheel diameter and overall wheel condition first, since even the correct tire size depends on a sound vintage wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 1932 Graham 56 Series?
A 550-17 bias-ply tire is the right starting point for a period-style 1932 Graham 56 Series because it preserves the vehicle's traditional sizing format and pre-war construction character. Within that fitment, the choice becomes whether a blackwall, wide whitewall, or double-whitewall best matches the car's presentation.
For some owners, the goal is a restrained driver with understated visual treatment, while others want a more formal restoration-minded appearance. If exact historical authenticity matters at a very high level, the final sidewall choice should be checked against marque references, old photos, or other vehicle-specific documentation.
How does tire construction affect the appearance of a restored 1932 Graham 56 Series?
On a restored 1932 Graham 56 Series, bias-ply construction does more than satisfy fitment needs; it also supports the car's overall pre-war visual character. The stance, sidewall shape, and general presentation of a 550-17 bias-ply tire look more in keeping with the period than a modern tire style would.
Appearance is only part of the decision, though, because an attractive tire still has to work with the car's actual wheels and intended road use. A carefully chosen sidewall treatment can strengthen the finished look, but proper wheel inspection and correct mounting remain essential on an older restoration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1932 Graham 56 Series?
Yes. A 1932 Graham 56 Series may have had wheel, suspension, or brake-related changes over the decades, and any of those can affect how a 550-17 tire sits and clears. Even when the original size is known, the car's current setup still determines whether the fitment remains appropriate.
A careful check should include wheel diameter, wheel condition, side-to-side clearance, steering travel, and any signs that the car sits differently than stock. Pre-war vehicles often carry long ownership histories, so confirming the actual hardware on the car is just as important as choosing the right tire size.
What should I inspect before driving a 1932 Graham 56 Series on new tires?
Before road use, inspect the wheels, valve stems, mounting surfaces, and the tires themselves for proper seating and inflation. On a 1932 Graham 56 Series, it also makes sense to look closely at suspension condition, steering play, brake function, and any age-related issues that could affect how the car behaves on the road.
A brief test at low speed is a sensible way to confirm that the tires run true and clear the body and suspension through normal steering movement. Collector cars that have spent time in storage should also be checked for fluid leaks, bearing issues, and other dormant-car problems before longer drives.
How should 550-17 tires on a collector 1932 Graham 56 Series be maintained?
550-17 tires on a collector 1932 Graham 56 Series should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long exposure to heat, sunlight, and moisture. Bias-ply tires on low-use vehicles also benefit from periodic movement so they are not left sitting in one position for extended periods.
Regular inspection matters because age and storage conditions can affect a collector car's tires even when tread wear is minimal. A pre-drive walkaround should include checking air pressure and looking for signs of air loss, while seasonal checks should include the wheels and overall suspension condition as well.
