The 1932 Reo 25 Series comes from an era when independent American makes still gave buyers distinctive engineering and styling choices, and surviving examples today tend to be maintained with a strong eye toward authenticity and roadworthiness. That makes tire selection more important than simply finding something that mounts. The 1932 Reo 25 Series uses a 6.50-17 bias-ply tire on a 17-inch rim, a traditional fitment that suits the vehicle’s pre-war character and wheel setup. For most owners, the real choice is how to stay faithful to that original-style sizing while paying close attention to wheel condition, overall tire presentation, and safe operation on a collector vehicle.
Which Tire Size Is Right for The 1932 Reo 25 Series
The 1932 Reo 25 Series uses one primary tire size: 6.50-17. It is a bias-ply fitment for a 17-inch rim, and the covered 8 Cyl. sub-model uses that same sizing. With only one primary size to identify, the decision shifts from size selection to choosing a tire that matches the vehicle’s traditional appearance, wheel setup, and intended road use.
A 6.50-17 tire uses the older numeric bias-ply sizing system, where 6.50 refers to the nominal section width in inches and 17 identifies the rim diameter. For a 1932 Reo 25 Series, that format is part of the vehicle’s pre-war tire character and keeps the fitment aligned with the kind of construction originally associated with the period. Numeric bias-ply sizes also carry a distinctly vintage look on the car. Choosing this size is mainly about preserving the proper wheel diameter relationship and confirming that the existing wheels are sound, correctly sized, and ready for road use.
Fitment is straightforward across the covered 1932 Reo 25 Series sub-models. The main reason to confirm the sub-model is to make sure the vehicle remains on the same 6.50-17 bias-ply sizing and 17-inch rim arrangement before selecting a replacement tire.

Frequently Asked Questions
Common questions for the 1932 Reo 25 Series usually center on 6.50-17 fitment, 17-inch rim compatibility, period-style tire selection, and the inspections that matter before putting a pre-war collector car back on the road.
Tire Size & Fitment
What tire size fits a 1932 Reo 25 Series?
The 1932 Reo 25 Series uses a 6.50-17 tire. This is a numeric bias-ply size, and it is the primary fitment associated with the vehicle covered here, including the 8 Cyl. sub-model.
That means the first goal is not sorting through multiple primary sizes, but confirming that the car still has the correct 17-inch wheels and has not been altered over the years. On an older collector vehicle, wheel condition, bead-seat integrity, and overall clearance should all be checked before mounting replacement tires.
What size rim does a 1932 Reo 25 Series use?
The 1932 Reo 25 Series uses a 17-inch rim with its 6.50-17 tire size. The rim diameter is a key part of the fitment, since the final number in the tire size corresponds to the wheel diameter the tire is built to mount on.
Rim diameter should be verified directly on the car, especially if the vehicle has been restored or modified at some point in its life. A pre-war vehicle can have replacement wheels or mixed components, so confirming the actual wheel size before selecting tires helps avoid fitment mistakes and mounting issues.
Does the 1932 Reo 25 Series 8 Cyl. use the same tire size?
Yes. The 1932 Reo 25 Series 8 Cyl. uses the same 6.50-17 bias-ply tire size as the main vehicle fitment. That keeps the fitment picture simple for owners of that sub-model.
Even with shared sizing, it is still worth checking the car’s actual wheel setup before ordering tires. Collector vehicles sometimes carry later wheel changes, old repairs, or mismatched rims, so confirming the 17-inch wheel diameter and inspecting for age, wear, or structural issues remains an important step.
Choosing the Right Tire
What should I consider when choosing a 6.50-17 tire for a 1932 Reo 25 Series?
Start with the correct primary size and construction. A 1932 Reo 25 Series uses a 6.50-17 bias-ply tire, so the main selection question is whether the replacement keeps the car aligned with its traditional pre-war fitment and appearance.
Beyond size, look closely at how the car will be used and what condition the wheels are in. A vehicle intended for restoration display may call for a different presentation than one used for regular touring, and any tire choice should be paired with careful inspection of wheels, brakes, steering components, and available clearance.
How do I choose between available 6.50-17 tires for a 1932 Reo 25 Series?
Choosing between 6.50-17 tires for a 1932 Reo 25 Series comes down to staying within the proper size while matching the vehicle’s intended look and use. On a pre-war car, owners often want a tire that complements the period character rather than a modern-looking substitute.
It also helps to think about how the car will spend its time once finished or maintained. A vehicle headed to shows, preservation events, or occasional local drives may have different priorities than one meant for longer collector tours, and the wheel setup should always be checked before making the final selection.
What rim-fitment details matter when choosing tires for a 1932 Reo 25 Series?
The most important rim-fitment detail is confirming that the car still uses the correct 17-inch wheels for the 6.50-17 tire size. Since this is an older bias-ply application, wheel condition matters just as much as the nominal tire size.
Attention should go to rust, cracks, flange condition, trueness, and any signs of previous repairs before new tires are mounted. Pre-war wheels and hardware can have decades of use behind them, so a proper inspection helps ensure the tire and wheel work together as intended once the vehicle is back on the road.
Restoration & Appearance
Which tire should I choose for a period-style 1932 Reo 25 Series?
For a period-style 1932 Reo 25 Series, the proper starting point is the original-size-style 6.50-17 bias-ply fitment. That sizing preserves the car’s pre-war stance and helps maintain the visual relationship between the tire, wheel, and body proportions.
Owners pursuing a highly exact restoration should also compare their tire choice against marque-specific history, period photography, and other authoritative references tied to the individual car. Even when the size is correct, details of presentation can matter on a carefully restored vehicle, especially if authenticity is part of the project goal.
Does correct tire fitment matter for a 1932 Reo 25 Series restoration?
Yes, correct tire fitment matters a great deal on a 1932 Reo 25 Series restoration. The 6.50-17 bias-ply size influences not only how the car sits, but also how naturally it presents as a pre-war automobile.
Using the right size helps preserve the vehicle’s proportions and avoids a mismatched look that can come from modernized sizing choices. It also reduces the chance of wheel-diameter errors, clearance problems, or an appearance that feels out of place on a restoration intended to reflect the character of the early 1930s.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1932 Reo 25 Series?
Yes. Modifications can affect tire fitment on a 1932 Reo 25 Series even when the intended tire size remains 6.50-17. Changes to wheels, suspension height, brake components, or body clearances can all alter how comfortably a replacement tire works on the car.
Any restored or updated vehicle should be checked as it sits today rather than assumed to match original dimensions. Wheel diameter, wheel width, steering travel, and fender clearance all deserve attention, particularly on pre-war cars that may have gone through multiple ownership periods and older mechanical revisions.
What should I inspect before driving a 1932 Reo 25 Series on new tires?
Before driving a 1932 Reo 25 Series on new tires, inspect the wheels, lug hardware, valve stems, and overall tire seating. It is also wise to look over the steering, brakes, suspension joints, and alignment-related components so the new tires are not being asked to compensate for worn mechanical parts.
A slow, careful road test is a sensible next step once inflation and installation have been confirmed. On a collector car of this age, attention should also go to wheel bearing condition, air retention, and any signs of rubbing or uneven contact before the vehicle is used for longer distances.
How should 6.50-17 tires on a collector 1932 Reo 25 Series be maintained?
6.50-17 tires on a collector 1932 Reo 25 Series should be maintained with regular pressure checks, visual inspections, and careful storage habits. Since collector cars often sit for long periods, sidewall condition, tread condition, and any sign of cracking, bulging, or air loss deserve more attention than mileage alone would suggest.
Storage conditions make a real difference on a low-use pre-war vehicle. Keeping the car away from prolonged sunlight, moisture, excessive heat, and ozone sources can help protect the tires between drives, and periodic inspection remains important even if the car only sees occasional touring or show use.
