The 1932 Reo 31 & 35 Series comes from an era when independent American automakers still gave buyers distinctive engineering and upscale presentation in the depths of the Depression. A surviving Reo from this period is often restored and driven with close attention to period character, and the tires play a big part in that look and stance. This vehicle uses a 650-18 bias-ply tire on an 18-inch rim. Available choices center on Firestone Balloon tires in either blackwall or 3.50-inch wide whitewall form. For a restoration-minded owner, the key decision is usually preserving the proper prewar appearance while also confirming wheel condition before road use.
Which Tire Size Is Right for The 1932 Reo 31 & 35 Series
The 1932 Reo 31 & 35 Series uses one primary tire size: 650-18. It is a bias-ply fitment for an 18-inch rim, and the covered 8 Cyl. sub-model uses the same size. That means the main decision is not between multiple primary sizes, but between available period-style tire presentations such as blackwall or wide whitewall while keeping wheel compatibility and intended use in mind.
A 650-18 numeric bias-ply size uses the leading number to indicate a nominal section width of about 6.50 inches, while the final number identifies the 18-inch rim diameter. For the 1932 Reo 31 & 35 Series, that format matches the traditional bias-ply construction associated with prewar driving feel and appearance. In this size, Firestone Balloon options include both blackwall and 3.50-inch wide whitewall styles. Choosing within 650-18 usually comes down to the visual presentation you want and confirming that the existing wheels match the required 18-inch diameter and appropriate rim-width range.
Tire fitment is straightforward for the covered 1932 Reo 31 & 35 Series sub-model. The listed configuration uses the same primary size, so the buyer's attention can stay on construction, sidewall appearance, and wheel condition rather than sorting through multiple fitment patterns.

Tire Size & Fitment
What tire size fits a 1932 Reo 31 & 35 Series?
The 1932 Reo 31 & 35 Series uses a 650-18 tire size. This is a numeric bias-ply fitment, and the covered 8 Cyl. sub-model uses that same primary size on an 18-inch rim.
That makes the next step less about choosing between different sizes and more about confirming the actual wheel setup on the car. A restored or modified vehicle may have had wheels changed over the years, so checking rim diameter, rim width, and overall clearance before mounting new tires is still important.
What size rim does a 1932 Reo 31 & 35 Series use?
The primary tire fitment for the 1932 Reo 31 & 35 Series uses an 18-inch rim. In 650-18, the available Firestone Balloon products are built around that 18-inch wheel diameter.
Rim diameter is the first measurement to confirm, but it should not be the only one. The wheel also needs to match the tire's intended width range, and an older car should have its wheels inspected for condition, trueness, and bead-seat integrity before any fresh bias-ply tires go into service.
Does the 1932 Reo 31 & 35 Series 8 Cyl. use the same tire size?
Yes. The covered 1932 Reo 31 & 35 Series 8 Cyl. uses the same 650-18 bias-ply tire size as the core fitment. That keeps sizing simple and preserves a consistent period-style fitment approach for this sub-model.
Even with a shared size, tire selection can still vary by appearance and wheel compatibility. A buyer choosing between blackwall and wide whitewall versions should verify the wheel dimensions and inspect the car for any changes that could affect clearance, especially on a vehicle that may have been restored decades ago.
Choosing the Right Tire
What should I consider when choosing a 650-18 tire for a 1932 Reo 31 & 35 Series?
Start with the confirmed 650-18 size, bias-ply construction, and 18-inch rim diameter used by the 1932 Reo 31 & 35 Series. From there, the decision usually comes down to the tire's visual presentation, the wheel dimensions on the car, and whether the car is being restored for show-oriented appearance or regular collector driving.
The available Firestone Balloon choices make sidewall style a meaningful factor, since blackwall and 3.50-inch wide whitewall versions create different looks. It also helps to compare product specifications such as rim-width range, weight, and load information where shown, then match those details to the actual wheel and vehicle setup.
What sidewall styles are available for 1932 Reo 31 & 35 Series tires?
For the 1932 Reo 31 & 35 Series in 650-18, available sidewall styles include blackwall and wide whitewall. The wide whitewall offering is a 3.50-inch whitewall in the Firestone Balloon line, while another Firestone Balloon option is finished as a blackwall.
That choice affects the car's visual character more than its core fitment. A blackwall usually gives a more restrained, utilitarian presentation, while a wide whitewall pushes the car toward a more formal restoration-oriented look. Either way, the tire still needs to match the wheel diameter and width used on the car.
What tire series are available for the 1932 Reo 31 & 35 Series?
The available 650-18 products for the 1932 Reo 31 & 35 Series are in the Firestone Balloon series. That keeps the fitment story simple, since the main distinctions are not between many different series names, but between sidewall treatments and the product specifications attached to each version.
For a buyer, that means comparing the details within the same series rather than trying to sort through unrelated tire families. Looking at sidewall style, rim-width range, weight, and any stated load figure will do more to narrow the right choice than focusing only on brand or series name.
Restoration & Appearance
Which tire should I choose for a period-style 1932 Reo 31 & 35 Series?
A period-style 1932 Reo 31 & 35 Series starts with the correct 650-18 bias-ply size on an 18-inch rim. Within that fitment, the Firestone Balloon line keeps the construction and overall presentation in step with the prewar character most restoration-minded owners want to preserve.
The remaining decision is usually blackwall versus wide whitewall, depending on how formal or restrained you want the finished car to look. When exact historical authenticity matters, tire appearance should be checked against marque references, photographs, and restoration documentation rather than assumed from size alone.
Does correct tire fitment matter for a 1932 Reo 31 & 35 Series restoration?
Yes, correct tire fitment has a major effect on the stance, visual balance, and overall credibility of a 1932 Reo 31 & 35 Series restoration. Using the proper 650-18 bias-ply size keeps the car aligned with the proportions expected from a prewar automobile of this type.
Appearance is only part of the story, though. A restoration should also account for wheel condition, proper mounting, and the way the tire sits within the fenders and suspension envelope. Even a visually accurate tire choice can create problems if the car's wheels or chassis have changed over time.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1932 Reo 31 & 35 Series?
Yes. A 1932 Reo 31 & 35 Series may have the correct primary size of 650-18, but modifications can still affect whether a given tire setup works as intended. Wheel changes, altered suspension height, brake conversions, or body repairs can all change how much space the tire has.
That is why an older collector car should be measured as it sits today rather than treated as untouched. Checking wheel diameter, wheel width, steering travel, and fender clearance helps prevent surprises, especially on a car that may have passed through several restorations or mechanical updates over the years.
What should I inspect before driving a 1932 Reo 31 & 35 Series on new tires?
Before driving a 1932 Reo 31 & 35 Series on new tires, inspect the wheels, valve hardware, and overall mounting condition along with the tires themselves. On the vehicle, confirm that nothing rubs at full steering angle and that the tires seat properly on sound 18-inch rims.
A prewar collector car also deserves a broader road-use check. Tire pressure, lug security, brake function, steering play, and suspension condition all influence how the car behaves once fresh bias-ply tires are installed. A cautious local test drive is a smart way to spot vibration, pull, or clearance issues early.
How should 650-18 tires on a collector 1932 Reo 31 & 35 Series be maintained?
650-18 tires on a collector 1932 Reo 31 & 35 Series should be kept properly inflated, inspected regularly, and protected from long periods of heat, sunlight, moisture, and ozone exposure. Because collector cars are often driven less, tire age and storage conditions matter just as much as tread appearance.
Routine checks should include sidewall cracking, cuts, bulges, uneven wear, and any sign of air loss. It also helps to look over the wheels and valve hardware whenever the tires are checked. A car that sits for long stretches benefits from periodic inspection before every meaningful drive, not just seasonal maintenance.
