1938 Graham Custom Supercharger Tires

The 1938 Graham Custom Supercharger uses a 650-16 tire size. This is a vintage numeric bias-ply size mounted on a 16-inch rim, and it is the primary fitment for the covered model.

That makes the first job fairly simple: confirm that the car still has 16-inch wheels and has not been changed to another wheel setup over the years. Once the size is confirmed, the real choice becomes selecting the right 650-16 tire style for the car, such as blackwall or wide whitewall, along with a bias-ply series that matches the vehicle's appearance and intended use.

The 1938 Graham Custom Supercharger uses a 16-inch rim with its 650-16 tire size. Product fitments in this size commonly pair with rim widths around 4.50 to 5.00 inches, with some variation depending on the tire series.

Rim diameter needs to be confirmed before any tire purchase, especially on a prewar car that may have seen wheel changes during restoration or long-term ownership. Wheel width also matters, since some 650-16 options are aimed at slightly narrower or more specific rim ranges, so the actual wheel on the car should be checked rather than assumed.

Yes. The covered 1938 Graham Custom Supercharger 6 Cyl. uses the same 650-16 bias-ply tire size. There is no separate primary size change within that sub-model listing.

That consistency helps narrow the search quickly, but it does not remove the need to inspect the car itself. A restored or modified Graham may be wearing different wheels than expected, and prewar cars can also vary in how much clearance they have around fenders and steering components if suspension parts, wheel offsets, or ride height have been altered.

Start with the correct 650-16 size and confirm that the car still uses a 16-inch wheel with a compatible width for the tire being considered. Since this Graham uses a bias-ply fitment, the next decision usually comes down to period-style presentation, intended driving use, and the specific tire series available in that size.

A buyer comparing 650-16 options should look at sidewall style, rim-width specification, load figure where stated, and tread character. A blackwall can suit a more understated presentation, while a wide whitewall creates a stronger prewar visual statement. Those details often matter more than simply picking the first tire that shares the size code.

The 1938 Graham Custom Supercharger's 650-16 fitment is available in both blackwall and wide whitewall styles. That gives the car two distinctly different visual directions while staying within the same primary tire size and bias-ply construction.

Sidewall style should be chosen with the car's restoration goal in mind rather than treated as a purely cosmetic afterthought. A wide whitewall gives the Graham a fuller late-1930s luxury presentation, while a blackwall keeps the look more restrained. The important point is to keep the correct 650-16 fitment first, then decide which appearance best suits the car.

In 650-16, the 1938 Graham Custom Supercharger has choices from BFGoodrich, Coker Classic, Firestone, Garfield, Excelsior, Lester, Goodyear, STA, and Tornel. Those brands appear across several classic bias-ply and specialty-style series in the correct size.

Brand alone should not decide the tire. It makes more sense to compare each option by sidewall style, series character, stated rim-width compatibility, and whether the tire is aimed at passenger-car presentation or a more utility-oriented tread style. On a prewar collector car, visual match and proper fitment are often just as important as the name on the sidewall.

A period-style 1938 Graham Custom Supercharger should begin with the correct 650-16 bias-ply size. From there, the decision usually comes down to whether the car looks best with a traditional blackwall or a wide whitewall, along with selecting a classic bias-ply series that suits the vehicle's presentation.

For many prewar restorations, tire appearance has a major effect on the car's stance and visual balance. Buyers focused on historical accuracy should compare the chosen sidewall treatment with period photos, marque-club guidance, and restoration documentation for their specific car. That approach is more reliable than assuming any currently available wide whitewall or blackwall automatically matches original delivery.

Yes, correct tire fitment matters a great deal on a 1938 Graham Custom Supercharger restoration. The right 650-16 bias-ply size helps preserve the car's intended proportions, wheel-to-fender relationship, and overall prewar character in a way that a casually substituted size may not.

Restoration-minded owners should think beyond simple diameter and make sure the tire also suits the wheel width and the appearance they want the car to carry. Even when a tire can be mounted, a different size or construction can change visual balance noticeably. On a car with styling as distinctive as a Graham, that can affect the finished result more than many buyers expect.

Yes. Modifications can affect tire fitment on a 1938 Graham Custom Supercharger even when the tire size remains 650-16. Changes to wheels, wheel width, offset, suspension height, brake components, or steering parts can alter how much space the tire has in real driving conditions.

A Graham that has been restored over many decades may not still match its original wheel and chassis setup exactly. Checking clearance at full steering lock, confirming wheel dimensions, and inspecting for rubbing around the fenders or suspension is worthwhile before settling on a tire. That is especially important when comparing different 650-16 product lines with different intended uses.

Before driving a 1938 Graham Custom Supercharger on new tires, inspect the wheels for damage, confirm the rim diameter and width, and make sure the tires are mounted and inflated appropriately for the application. The steering, suspension, and brake components should also be checked for condition and proper operation.

A road test is safest after confirming there is no interference through the full steering range and no signs of air loss, sidewall contact, or uneven stance. On a prewar collector car, it also makes sense to inspect wheel bearings, alignment-related wear, and general chassis condition, since tire performance can only be as sound as the hardware supporting it.

650-16 tires on a collector 1938 Graham Custom Supercharger should be inspected regularly for pressure retention, tread wear, cracking, bulges, cuts, and any change in how the car sits or steers. Because collector cars are often driven infrequently, condition and age matter just as much as tread depth.

Storage also affects tire life. Keeping the Graham away from prolonged sunlight, excess heat, standing moisture, and ozone sources helps preserve the sidewalls and casing. It is also smart to check the tires before every meaningful outing, since long parked periods can hide slow air loss or age-related deterioration that may not be obvious at a glance.
