The 1933 Graham 65 Series comes from a period when independent American automakers still carved out distinct identities through styling, engineering, and road manners rather than sheer production volume. For many owners today, the appeal lies in preserving that unmistakable early-1930s character while keeping the car ready for careful touring and show use. Tire fitment for the 1933 Graham 65 Series centers on a 550-17 bias-ply tire on a 17-inch rim, which keeps the car in its proper prewar visual and driving context. Available choices focus on presentation, with Blackwall, Double-Whitewall, and Wide Whitewall versions in the BFGoodrich Silvertown Classic Bias Ply line. The right selection depends on how original-looking, road-ready, or restoration-oriented the finished car needs to be.
Which Tire Size Is Right for The 1933 Graham 65 Series
The 1933 Graham 65 Series uses one primary tire size: 550-17, a bias-ply fitment for a 17-inch rim. The 6 Cyl. sub-model uses that same size, so the decision is less about choosing between sizes and more about selecting the right sidewall appearance and period-style tire presentation for the car.
A 550-17 size uses the vintage numeric bias-ply system, where the 550 indicates an approximate 5.50-inch nominal section width and the 17 identifies the wheel diameter in inches. On the 1933 Graham 65 Series, this keeps the car in the tire construction style associated with its era and preserves the tall, upright visual character expected on an early-1930s automobile. Available choices in this size include BFGoodrich Silvertown Classic Bias Ply options with Blackwall, Double-Whitewall, and Wide Whitewall sidewall treatments. That makes 550-17 the size to evaluate when appearance, restoration goals, and proper wheel compatibility all need to stay aligned.
Fitment is straightforward for the covered 1933 Graham 65 Series sub-models because the same primary tire size is used across the range shown here. Checking the exact sub-model still helps confirm that the car remains on its intended 17-inch wheel and bias-ply tire setup.

1933 Graham 65 Series 6 Cyl.
The 1933 Graham 65 Series 6 Cyl. uses the same 550-17 bias-ply tire fitment as the model core. That keeps tire selection focused on period-style presentation, sidewall appearance, and confirming that the car still has the correct 17-inch wheel setup before replacement.
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.

These FAQs focus on 1933 Graham 65 Series tire size, 17-inch rim fitment, bias-ply construction, sidewall appearance choices, and the practical checks worth making before road use on a prewar collector car.
Tire Size & Fitment
What tire size fits a 1933 Graham 65 Series?
The 1933 Graham 65 Series uses a 550-17 tire size. This is a bias-ply fitment on a 17-inch rim, and the covered 6 Cyl. sub-model uses that same primary size as well.
That makes the first step simple: confirm that the car is still running the correct 17-inch wheels and has not been changed to a different wheel diameter over the years. Once size is confirmed, the real choice becomes sidewall appearance and restoration style, since 550-17 is available in more than one traditional presentation.
What size rim does a 1933 Graham 65 Series use?
The 1933 Graham 65 Series uses a 17-inch rim with its 550-17 tire size. That rim diameter matches the tire code itself, where the final number identifies the wheel diameter in inches.
Rim diameter is the non-negotiable starting point when replacing tires on a prewar car. A Graham that has had wheel changes at some point should be measured directly before ordering, and the wheel's width and overall condition should also be checked so the new 550-17 bias-ply tires are being matched to a sound, compatible wheel.
Does the 1933 Graham 65 Series 6 Cyl. use the same tire size?
Yes. The 1933 Graham 65 Series 6 Cyl. uses the same 550-17 bias-ply tire size as the model core. There is no separate alternate primary size within the covered sub-model fitment shown here.
That consistency helps keep selection straightforward, but it is still worth confirming the actual wheel setup on the car. Older collector vehicles are often restored, modified, or pieced together over time, so checking the mounted wheel diameter and the car's present clearance condition remains a smart step before replacing a full set.
Choosing the Right Tire
What should I consider when choosing a 550-17 tire for a 1933 Graham 65 Series?
Start with the basics: the correct size is 550-17, the construction is bias-ply, and the wheel diameter is 17 inches. From there, the choice centers on how the car is used and presented, because the available options stay within the same size and BFGoodrich Silvertown Classic Bias Ply series.
For many owners, the deciding factor is appearance rather than fitment. A Blackwall gives a plainer, more understated look, while Double-Whitewall and Wide Whitewall versions create a more formal prewar presentation. Tire age on the rest of the set, wheel condition, and the overall restoration direction should all be considered before settling on one style.
What sidewall styles are available for 1933 Graham 65 Series tires?
The 1933 Graham 65 Series has 550-17 tire options in Blackwall, Double-Whitewall, and Wide Whitewall sidewall styles. All of those choices remain within the same bias-ply size and the same BFGoodrich Silvertown Classic Bias Ply family.
That means the sidewall choice mainly changes the car's visual character rather than its basic fitment. Owners aiming for a restrained touring look may lean toward Blackwall, while a more formal restoration-style presentation may point toward one of the whitewall options. Matching the sidewall treatment to the car's trim, era feel, and intended use usually brings the best result.
What brands offer tires for the 1933 Graham 65 Series?
BFGoodrich is the available brand for the 1933 Graham 65 Series in the 550-17 size. The choices shown here are all bias-ply tires in the Silvertown Classic Bias Ply series, with variation coming from sidewall treatment rather than brand changes.
Since the brand selection is focused, comparison should shift to the details that actually differ: Blackwall versus whitewall presentation and how that supports the car's restoration style. It is also helpful to confirm that every tire on the car will match in size, construction, and appearance, especially on a prewar vehicle where uneven tire choices can stand out quickly.
Restoration & Appearance
Which tire should I choose for a period-style 1933 Graham 65 Series?
A 550-17 bias-ply tire is the correct period-style starting point for a 1933 Graham 65 Series. Keeping the original size format and bias-ply construction preserves the visual proportions and traditional stance associated with a prewar Graham.
The finer decision comes down to sidewall treatment. Blackwall creates a simpler look, while Double-Whitewall or Wide Whitewall versions make a stronger visual statement. If exact originality matters, the final appearance choice should be checked against marque references, restoration photography, or other vehicle-specific historical material rather than relying on size alone.
How does tire construction affect the appearance of a restored 1933 Graham 65 Series?
Tire construction matters quite a bit on a restored 1933 Graham 65 Series because bias-ply tires carry the visual character expected on an early-1930s car. The 550-17 bias-ply format supports the tall, narrow, upright look that suits prewar wheel openings and body proportions.
Appearance is not only about size; sidewall treatment also changes the personality of the finished car. A Blackwall keeps things restrained, while whitewall versions create a dressier presentation. For an owner focused on restoration authenticity, keeping the construction and size in period style usually has as much visual impact as paint, trim, or wheel finish.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1933 Graham 65 Series?
Yes. Even though the primary fitment is a 550-17 bias-ply tire on a 17-inch rim, later wheel changes, brake work, suspension alterations, or body modifications can change what actually clears on the car today. That is especially true on older vehicles that may have passed through several owners and restorations.
A careful check should include actual wheel diameter, wheel width, tire-to-fender clearance, and steering clearance at full lock. Suspension condition also matters, since worn bushings, sagging springs, or misalignment can create rubbing that was not part of the original design. Verifying the current setup prevents ordering the right size for the wrong configuration.
What should I inspect before driving a 1933 Graham 65 Series on new tires?
Before road use, inspect the wheel condition, valve hardware, mounting quality, and inflation pressure, then make sure the tires seat properly and rotate without visible wobble. A short, careful test should also confirm that the 550-17 tires clear the fenders, suspension, and steering components through normal movement.
The rest of the car deserves equal attention on a prewar vehicle. Brake function, steering play, suspension wear, and wheel bearing condition should all be checked before any meaningful drive. New tires improve readiness, but they do not offset age-related issues elsewhere in the chassis that can affect safety and road manners.
How should 550-17 tires on a collector 1933 Graham 65 Series be maintained?
Collector-car tires like 550-17 bias-ply tires should be inspected regularly for air loss, sidewall cracking, bulges, cuts, and uneven wear. Even on a lightly driven 1933 Graham 65 Series, age and storage conditions matter just as much as tread depth because long parked periods can be hard on vintage-style tires.
Proper storage helps preserve them between drives. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can slow deterioration, and maintaining correct inflation helps protect the tire's shape while parked. A brief inspection before every outing is worthwhile, since collector cars often spend more time stored than actually on the road.
