The 1936 Graham Supercharger comes from a fascinating prewar period when independent American automakers were still willing to experiment with styling and performance. Graham’s supercharged models stand apart for their distinctive presence and for the kind of engineering ambition that still draws serious collector interest today. Tire fitment for this car is straightforward, centered on the 6.25-16 bias-ply size used on a 16-inch rim. That keeps the decision focused less on finding the right size and more on choosing the right period-style bias-ply tire presentation for the car’s intended use. For a restoration-minded owner, the goal is balancing authentic prewar character with careful wheel and condition checks before road use.
Which Tire Size Is Right for The 1936 Graham Supercharger
The 1936 Graham Supercharger uses one primary tire size: 6.25-16 in bias-ply construction on a 16-inch rim. The same size applies to the covered 6 Cyl. sub-model, so the main decision is not size selection but choosing a tire that suits the car’s prewar appearance, restoration direction, and actual wheel condition before it goes back on the road.
In a numeric bias-ply size like 6.25-16, the 6.25 refers to the tire’s nominal section width in inches and the 16 identifies the wheel diameter. This is a traditional bias-ply fitment that matches the kind of tire construction associated with a 1936 Graham Supercharger and helps preserve its prewar driving character and visual stance. Numeric bias-ply sizing is especially familiar on vehicles of this era because it reflects period tire standards rather than modern metric sizing. Choosing this size keeps the fitment centered on the proper vintage format while leaving room to compare tire appearance and overall restoration priorities.
Fitment is simple across the covered 1936 Graham Supercharger sub-models because the same primary tire size is used throughout. Checking the exact sub-model still helps confirm that the car remains on its proper 16-inch wheel setup before selecting a replacement tire.

Frequently Asked Questions
Owners of a 1936 Graham Supercharger usually need clear guidance on 6.25-16 fitment, 16-inch rim compatibility, period-style bias-ply selection, restoration appearance, and the condition checks that matter before a prewar car returns to road use.
Tire Size & Fitment
What tire size fits a 1936 Graham Supercharger?
The 1936 Graham Supercharger uses a 6.25-16 tire in bias-ply construction. That is the primary fitment for this model, and it follows the traditional numeric sizing format commonly seen on prewar American cars.
Using the correct size matters because older vehicles are especially sensitive to wheel diameter, tire proportions, and clearance around fenders and suspension parts. A Graham that has been modified, fitted with different wheels, or left unused for long periods should have its actual wheel setup and overall tire condition checked before replacement.
What size rim does a 1936 Graham Supercharger use?
The 1936 Graham Supercharger uses a 16-inch rim with its 6.25-16 tire fitment. That rim diameter is an important part of the tire size itself, since the final number in 6.25-16 identifies the wheel diameter the tire is built to mount on.
Rim diameter should be confirmed before buying tires, especially on a collector car that may have changed wheels over the years. Measuring the wheel and checking its condition can prevent mismatch problems and also helps you evaluate whether the car is still set up in a way that suits traditional bias-ply fitment.
Does the 1936 Graham Supercharger 6 Cyl. use the same tire size?
Yes. The covered 1936 Graham Supercharger 6 Cyl. uses the same 6.25-16 bias-ply tire size as the model core. That makes fitment more straightforward than on vehicles where different trim levels or configurations require different tire sizes.
Even with shared sizing, it is still worth confirming that the car remains on the correct 16-inch wheels and has not been altered with later rims or suspension changes. On a prewar vehicle, tire choice often comes down to preserving the right overall look and maintaining proper fit rather than sorting between multiple factory sizes.
Choosing the Right Tire
What should I consider when choosing a 6.25-16 tire for a 1936 Graham Supercharger?
Start with the correct 6.25-16 size and bias-ply construction, since that is the primary fitment for the 1936 Graham Supercharger. For a prewar car like this, the decision is usually about selecting a tire that maintains the right vintage format and visual character rather than moving between several different fitment sizes.
Wheel condition, intended use, and restoration goals all matter. A car built for show presentation may call for a different appearance choice than one driven regularly on back roads or touring events. It also helps to inspect the wheels for rust, damage, or bead-seat issues before mounting fresh tires on an older chassis.
How do I choose between the available 6.25-16 tires for a 1936 Graham Supercharger?
Choose between 6.25-16 tires by staying with the proper bias-ply size first, then comparing the visual style and overall character that best suits the 1936 Graham Supercharger. On a car from this era, appearance and period presentation are often just as important as simple dimensional fitment.
Think about how the Graham will be used and how closely the tire should support the rest of the restoration. A car shown as a carefully preserved prewar automobile may benefit from a more traditional look, while a driver still needs the same attention to wheel integrity, tire age, and safe mounting on sound 16-inch rims.
What rim-fitment details should I compare when choosing 1936 Graham Supercharger tires?
The first rim-fitment detail is diameter, since the 1936 Graham Supercharger uses a 16-inch wheel with its 6.25-16 tire size. Beyond diameter, the wheel itself should be appropriate for bias-ply use and in sound condition, especially on a vehicle that may still have older restored or original-style rims.
Checking the wheel carefully helps avoid problems that a new tire alone cannot solve. Look for bent flanges, corrosion, poor previous repairs, and anything that could affect bead seating. Tire selection on a prewar car should always be tied to the actual wheel on the vehicle, not just the size stamped into the tire.
Restoration & Appearance
Which tire should I choose for a period-style 1936 Graham Supercharger?
A period-style 1936 Graham Supercharger should begin with the correct 6.25-16 bias-ply size, since that keeps the tire format aligned with the car’s prewar character. The right starting point is less about modern substitution and more about maintaining the proportions and construction style that suit the vehicle’s era.
Appearance choices should support the way the car is being restored, whether that means a preserved driver or a more formal show presentation. When exact originality matters, it is wise to compare the tire’s look against marque references, period photography, and other authoritative restoration sources rather than assuming any vintage-style tire is automatically correct.
Does correct tire fitment matter for a 1936 Graham Supercharger restoration?
Yes, correct tire fitment plays a major role in a 1936 Graham Supercharger restoration. The proper 6.25-16 bias-ply size affects not only how the car looks but also how naturally it sits on its wheels and how convincingly it reflects prewar automotive proportions.
Restoration-minded owners usually notice that tires influence stance, side profile, and overall presentation as much as many visible trim pieces. Fitment also has a practical side, since the wrong wheel diameter or an unsuitable replacement can create mounting and clearance problems. Getting the tire size right is one of the foundations of a coherent vintage restoration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1936 Graham Supercharger?
Yes, modifications can affect tire fitment on a 1936 Graham Supercharger even when the intended replacement size remains 6.25-16. Changes to wheels, suspension height, brake components, or body clearances can all influence how comfortably a traditional bias-ply tire works on the car.
A Graham with later wheels or altered suspension should be checked at full steering travel and normal ride height before new tires are mounted. Collector cars often accumulate changes over decades, so measuring the actual wheel diameter and inspecting clearance around fenders and chassis parts is more useful than assuming the setup is still original.
What should I inspect before driving a 1936 Graham Supercharger on new tires?
Before driving a 1936 Graham Supercharger on new tires, inspect the wheels, lug hardware, valve stems, and the surrounding suspension and steering components. The tires themselves should be checked for proper inflation, secure mounting, and any signs that the wheel condition could affect bead seating or long-term air retention.
A prewar car that has spent long periods parked deserves extra attention before heading onto the road. It helps to look for cracked bushings, loose steering parts, brake issues, and any rubbing marks near the tires. A cautious initial drive at moderate speed can reveal vibration, pull, or clearance issues before a longer outing.
How should 6.25-16 tires on a collector 1936 Graham Supercharger be maintained?
6.25-16 tires on a collector 1936 Graham Supercharger should be kept properly inflated, inspected regularly, and protected from the kinds of storage conditions that accelerate aging. Bias-ply tires on low-use vehicles deserve close attention because time, heat, sunlight, and inactivity can affect them even when tread wear is minimal.
Routine checks should include sidewall cracking, cuts, bulges, uneven wear, and gradual air loss. It also helps to keep the car on a clean, dry surface and away from ozone sources such as electric motors or certain shop equipment. A vintage car driven occasionally should have its tires evaluated by condition and age, not mileage alone.
