The 1932 Hupmobile 322 Series comes from a fascinating prewar period when independent American automakers still competed on style, engineering, and road manners in a rapidly changing market. For owners restoring or maintaining one today, tire choice is closely tied to preserving that early-1930s driving character and proper stance. This Hupmobile uses a 6.00-17 bias-ply tire on a 17-inch rim, keeping the fitment firmly in traditional vintage territory. The main decision is less about multiple sizes and more about choosing the right period-style tire within that fitment. That makes wheel condition, construction choice, and overall presentation especially important before putting the car back into regular road use.
Which Tire Size Is Right for The 1932 Hupmobile 322 Series
The 1932 Hupmobile 322 Series uses one primary tire size: 6.00-17 in bias-ply construction on a 17-inch rim. The 6 Cyl. sub-model follows that same fitment, so the real decision is choosing the right vintage-style tire within that size and confirming that the wheels and overall vehicle setup still match the original-style configuration.
A 6.00-17 tire uses a vintage numeric bias-ply size format in which the first number reflects the nominal section width in inches and the final number identifies the wheel diameter. On the 1932 Hupmobile 322 Series, this sizing matches the car's traditional prewar fitment and keeps the tire choice aligned with its original-era wheel design and appearance. Bias-ply construction is an important part of how a car from this period sits and presents visually, especially on a restoration-oriented vehicle. Choosing this size means focusing on proper 17-inch wheel compatibility, sound wheel condition, and the kind of period-style look you want the car to carry on the road.
Tire fitment is straightforward across the covered 1932 Hupmobile 322 Series sub-models. The key point is confirming the exact sub-model and wheel setup so the correct vintage 6.00-17 bias-ply fitment stays in place.

Frequently Asked Questions
These FAQs focus on the 1932 Hupmobile 322 Series tire size, 17-inch rim fitment, bias-ply construction, restoration-minded tire selection, and the basic inspection and maintenance checks that matter before road use.
Tire Size & Fitment
What tire size fits a 1932 Hupmobile 322 Series?
The 1932 Hupmobile 322 Series uses a 6.00-17 tire in bias-ply construction. That is the primary fitment for this vehicle, and it matches a 17-inch wheel diameter rather than a modern metric sizing system.
The practical next step is to confirm that the car still has its correct 17-inch wheels and has not been changed to another diameter over the years. On an older collector car, wheel swaps, mixed wheels, or long-stored parts can complicate a simple size decision, so the mounted wheel should always be checked before selecting new tires.
What size rim does a 1932 Hupmobile 322 Series use?
The 1932 Hupmobile 322 Series uses a 17-inch rim with its 6.00-17 tire fitment. In this size format, the final number in the tire code identifies the wheel diameter, so the tire is intended for a 17-inch wheel.
That rim diameter should be verified on the actual car before replacing tires, especially on a prewar vehicle that may have seen decades of repairs or parts changes. Checking wheel diameter along with overall wheel condition helps prevent ordering a correct tire size for the model but the wrong fitment for the wheels currently on the vehicle.
Does the 1932 Hupmobile 322 Series 6 Cyl. use the same tire size?
Yes. The 1932 Hupmobile 322 Series 6 Cyl. uses the same 6.00-17 bias-ply tire size as the model covered here. That keeps fitment straightforward at the sub-model level and avoids the need to sort through multiple primary sizes.
Even with shared fitment, it still helps to inspect the car closely before choosing tires. A restoration, older wheel replacement, or long-ago modification can leave a car wearing something different from its intended setup, so the most useful approach is to confirm the mounted wheel diameter and overall wheel condition before moving ahead.
Choosing the Right Tire
What should I consider when choosing a 6.00-17 tire for a 1932 Hupmobile 322 Series?
Start with the correct primary fitment: 6.00-17 in bias-ply construction on a 17-inch rim. For a prewar Hupmobile, that size choice is closely tied to the car's intended look, stance, and traditional road character, so staying within the proper vintage fitment is the first priority.
After that, focus on the condition and compatibility of the wheels already on the car. An early-1930s vehicle may have original wheels, restored wheels, or older replacement parts, and each should be checked carefully for diameter, structural condition, and overall suitability before new tires are mounted and the car returns to regular road use.
How do I choose between the available 6.00-17 tires for a 1932 Hupmobile 322 Series?
The main factors are maintaining the correct 6.00-17 bias-ply fitment and selecting a tire that suits the car's intended use and presentation. On a vehicle like the 1932 Hupmobile 322 Series, appearance and proper vintage fitment usually matter just as much as basic size compatibility.
A touring-oriented driver may prioritize road-ready condition and dependable wheel compatibility, while a restoration-minded owner may focus more heavily on a traditional early-1930s look. Looking at the tire in the context of the car's finish, ride height, and wheel condition usually leads to a better decision than treating size alone as the only concern.
What rim-fitment details matter when choosing tires for a 1932 Hupmobile 322 Series?
The most important rim detail is the 17-inch wheel diameter required by the 6.00-17 tire size. Beyond diameter, the wheel itself should be appropriate for a vintage bias-ply application and in sound enough condition to support safe mounting and road use.
On an older collector car, tire fitment is affected by more than the printed size on the sidewall. Wheel age, previous repairs, rust, bent flanges, and changes made during an earlier restoration can all influence how well a tire mounts and runs, so a careful wheel inspection is an important part of choosing the right tire.
Restoration & Appearance
Which tire should I choose for a period-style 1932 Hupmobile 322 Series?
A 6.00-17 bias-ply tire is the right starting point for a period-style 1932 Hupmobile 322 Series because it matches the vehicle's primary vintage fitment and preserves the traditional construction associated with cars from this era. That approach keeps the tire choice visually in step with the car's prewar character.
Owners focused on historical accuracy should also consider the specific presentation goals of the restoration. Tire construction, tread styling, and sidewall appearance can all affect how authentic the finished car feels, so it is wise to compare the tire choice with marque references, restoration photos, and other authoritative period guidance when originality matters.
Does correct tire fitment matter for a 1932 Hupmobile 322 Series restoration?
Yes, correct tire fitment matters significantly on a 1932 Hupmobile 322 Series restoration. The proper 6.00-17 size and bias-ply construction influence not only whether the tire belongs on the car, but also how the vehicle sits, how the wheel openings are filled, and how convincingly the finished restoration reflects its era.
A tire that departs too far from the intended vintage fitment can change the visual balance of the car even before it changes the driving experience. Restoration-minded owners usually get better results by treating tire choice as part of the car's overall presentation, alongside wheel finish, ride height, and the broader historical goals of the project.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1932 Hupmobile 322 Series?
Yes. Modifications can affect tire fitment on a 1932 Hupmobile 322 Series even when the intended tire size remains 6.00-17. Wheel changes, brake work, suspension alterations, or body repairs carried out over many decades can all change the available space or alter the wheel setup enough to matter.
A car that has been restored or updated should be checked for actual wheel diameter, wheel condition, and clearance at full steering movement before new tires are installed. That step is especially important on prewar vehicles, where old modifications may not be obvious until the tire is mounted and the car is back on the ground.
What should I inspect before driving a 1932 Hupmobile 322 Series on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and the general condition of the suspension and steering components. Tire pressure should be set correctly for the tire and wheel setup being used, and the mounted tires should be checked for proper seating and any visible clearance concerns.
A prewar car also deserves a careful walk-around after the first short drive. Looking for rubbing, unusual vibration, air loss, or movement at the wheel attachment points can catch problems early, and it is especially helpful on a vehicle that may have spent long periods in storage or has recently returned to service after restoration work.
How should 6.00-17 tires on a collector 1932 Hupmobile 322 Series be maintained?
Collector-car tires should be inspected regularly even if the car is driven only occasionally. On a 1932 Hupmobile 322 Series, that means watching for cracking, cuts, bulges, tread wear, and slow air loss, while also keeping the tires properly inflated and the car stored away from prolonged heat, sunlight, and ozone sources.
Low annual mileage does not eliminate the need for inspection because age and storage conditions affect vintage tires as much as road use does. Periodic checks of wheel condition and tire pressure, along with a close look before longer drives, help the car stay road-ready and reduce the chance of discovering a problem after the trip has already started.
