The 1932 Hupmobile 326 comes from an era when independent American automakers still competed on style, engineering character, and road presence. For owners restoring or maintaining one today, tire choice has a major effect on stance, drivability, and the period feel of the car. This model uses a 6.50-17 bias-ply tire on a 17-inch rim, which keeps the fitment rooted in its original prewar sizing convention. The main decision is not sorting through multiple factory sizes, but choosing the right 6.50-17 tire for appearance and intended use. That makes wheel confirmation, overall condition, and preservation goals especially important before putting the car back on the road.
Which Tire Size Is Right for The 1932 Hupmobile 326
The 1932 Hupmobile 326 uses one primary tire size: 6.50-17, a bias-ply fitment for a 17-inch rim. The 8 Cyl. sub-model shares that same size, so the real decision is choosing the right tire within 6.50-17 and making sure the wheel and overall vehicle setup still match the original-style fitment.
A 6.50-17 tire is a vintage numeric bias-ply size, where 6.50 refers to the nominal section width in inches and 17 identifies the wheel diameter. On the 1932 Hupmobile 326, this construction suits the car's prewar chassis character and traditional tire profile. Buyers looking at this size are usually balancing period-style appearance with road-use practicality rather than deciding between multiple primary fitments. The key is confirming that the car still has the proper 17-inch wheels and that wheel condition, clearance, and restoration goals support staying with the original-style bias-ply setup.
Tire fitment is straightforward across the covered 1932 Hupmobile 326 sub-models. The main value in checking the exact sub-model is confirming that the car still carries the same original-style wheel and tire setup before selecting a replacement.

Frequently Asked Questions
These FAQs focus on 1932 Hupmobile 326 tire sizing, 17-inch rim fitment, period-style bias-ply selection, restoration considerations, and the basic inspection steps that matter before driving a prewar collector car.
Tire Size & Fitment
What tire size fits a 1932 Hupmobile 326?
The 1932 Hupmobile 326 uses a 6.50-17 tire size. This is a numeric bias-ply fitment built for a 17-inch wheel, and it is the primary size associated with the model covered here.
That means the first step is verifying that the car still has the correct 17-inch rims and has not been changed to a different wheel setup over the years. On a prewar car, wheels, brakes, suspension height, and body clearances may have been altered during restoration or long-term ownership, so checking the actual car before choosing a replacement tire is still important.
What size rim does a 1932 Hupmobile 326 use?
The 1932 Hupmobile 326 uses a 17-inch rim with its 6.50-17 tire size. In this sizing format, the final number identifies the wheel diameter, so the tire is intended for a 17-inch wheel rather than a smaller modern rim.
Rim diameter is only part of the fitment picture on an older vehicle. It also helps to inspect the wheel itself for condition, correct width, bead-seat integrity, and any signs of damage or previous repairs. A collector car that has sat for long periods can have wheel issues that are easy to overlook until the tires are being replaced.
Does the 1932 Hupmobile 326 8 Cyl. use the same tire size?
Yes. The 1932 Hupmobile 326 8 Cyl. uses the same 6.50-17 bias-ply tire size as the core model fitment. There is no separate primary tire size change within the covered sub-model information for that configuration.
That simplifies selection, because the decision is not about choosing between different factory sizes for different trims. Instead, the focus shifts to making sure the vehicle still retains its correct wheel setup and then choosing a 6.50-17 tire that matches the car's restoration direction, visual style, and intended road use.
Choosing the Right Tire
What should I consider when choosing a 6.50-17 tire for a 1932 Hupmobile 326?
Start with the correct primary size, which is 6.50-17, and stay with the proper bias-ply construction for this fitment. On a car from this era, that size and construction choice play a major role in preserving the traditional profile, stance, and overall visual balance of the vehicle.
After size confirmation, attention should shift to the actual wheel condition and how the car will be used. A touring car driven occasionally around town may call for a different priority than a restoration built mainly for show presentation. Tire age, wheel integrity, suspension condition, and how closely the car follows an original-style setup all matter before installation.
How do I choose between available 6.50-17 tires for a 1932 Hupmobile 326?
The best way to compare 6.50-17 choices for a 1932 Hupmobile 326 is to begin with fitment and appearance. Since the car uses one primary size, the decision usually comes down to whether the tire delivers the right period-style look and whether it suits a preservation-minded driver or a more road-oriented collector owner.
It also helps to look closely at the vehicle's current state rather than the catalog size alone. A car with original-style wheels and a careful restoration plan may point toward one kind of traditional presentation, while a car that has seen older repairs or hardware changes may need extra wheel and clearance checks before a final tire is chosen.
What rim-fitment details should I compare when choosing 1932 Hupmobile 326 tires?
The most important rim-fitment detail for a 1932 Hupmobile 326 is that the tire must match a 17-inch wheel, since the correct primary size is 6.50-17. Beyond diameter, older wheels should be inspected for condition, trueness, bead-seat integrity, and any signs of age-related wear.
A collector vehicle can still have the correct nominal wheel size and yet need attention before new tires go on. Rust, prior repairs, bent rims, and mismatched wheels from earlier ownership can all affect fitment and serviceability. Careful wheel inspection is especially worthwhile on prewar cars that may have spent long stretches stored or off the road.
Restoration & Appearance
Which tire should I choose for a period-style 1932 Hupmobile 326?
For a period-style 1932 Hupmobile 326, the starting point is the correct 6.50-17 bias-ply size. That sizing and construction align with the car's prewar character and help preserve the tall, traditional visual proportions that matter so much on an early 1930s automobile.
A restoration-minded owner should think about more than size alone. The car's stance, wheel finish, body presentation, and intended use all influence whether a given tire feels right on the vehicle. When strict originality matters, marque-specific historical references and restoration documentation remain the best way to confirm whether a particular visual treatment matches the car's build.
Does correct tire fitment matter for a 1932 Hupmobile 326 restoration?
Yes, correct tire fitment matters a great deal on a 1932 Hupmobile 326 restoration. Tire size has a strong effect on ride height, fender-to-tire proportion, and the overall visual impression of the car, especially on a prewar vehicle where tall sidewalls are part of the design language.
Using the proper 6.50-17 format helps keep the car visually grounded in its era, but condition and compatibility still need attention. A carefully restored body paired with incorrect wheels or worn rims can undermine the result. Checking the actual wheel setup before mounting tires is just as important as selecting the proper period-style size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1932 Hupmobile 326?
Yes. Modifications can affect tire fitment on a 1932 Hupmobile 326 even when the nominal tire size remains 6.50-17. Changes to wheels, suspension height, brake components, or body clearance can alter how the tire sits in the wheel opening and how much room it has during steering and road movement.
That is why an older collector car should be checked as it exists today, not only as it may have left the factory. A Hupmobile that has had replacement wheels, suspension work, or long-ago restoration changes may need closer measurement and inspection before new tires are mounted and driven at road speed.
What should I inspect before driving a 1932 Hupmobile 326 on new tires?
Before driving a 1932 Hupmobile 326 on new tires, inspect the wheels, valve hardware, mounting surfaces, and overall tire seating. It also makes sense to check steering movement, brake condition, and whether the tires clear fenders and suspension components through the normal range of motion.
A prewar collector car benefits from a broader safety check before road use. Look for loose wheel hardware, uneven ride height, signs of suspension wear, and anything that suggests the car has been sitting for an extended period. Tire pressure should be set appropriately, and any vibration or pull on the first drive deserves immediate attention.
How should 6.50-17 tires on a collector 1932 Hupmobile 326 be maintained?
6.50-17 tires on a collector 1932 Hupmobile 326 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Because collector cars often see limited mileage, tire age and condition can matter just as much as tread depth when deciding whether a tire is still roadworthy.
Routine inspection should include looking for sidewall cracking, cuts, bulges, flat spotting, and slow air loss. Storage away from prolonged sunlight, moisture, and ozone-producing equipment helps protect older-style tires between drives. Even a car that is rarely used should have its tires checked before each outing, especially after long periods of inactivity.
