The 1932 Studebaker 55 Series comes from an era when independent automakers still expressed a strong identity through engineering, proportions, and road manners, and tire choice played a visible role in that presentation. For owners of these early 1930s cars, the tire decision is closely tied to both appearance and proper vintage fitment. The 1932 Studebaker 55 Series uses a 550-18 bias-ply tire on an 18-inch rim, keeping the car in the sizing language and construction style of its period. Within that size, blackwall, wide whitewall, and double-whitewall options are available across several historic tire lines. The key is choosing a tire that suits the car's restoration character, wheel setup, and intended road use.
Which Tire Size Is Right for The 1932 Studebaker 55 Series
The 1932 Studebaker 55 Series uses one primary tire size: 550-18, a bias-ply fitment for an 18-inch rim. The 6 Cyl. sub-model shares that same size, so the main decision is not which primary size fits, but which 550-18 tire best matches the car's appearance, wheel width, and restoration or driving goals.
A 550-18 size uses the older numeric bias-ply system, where the 550 refers to an approximate 5.50-inch nominal section width and the 18 identifies the wheel diameter in inches. On the 1932 Studebaker 55 Series, this is a traditional bias-ply fitment that preserves the period construction and visual character expected on an early 1930s car. Available choices include Excelsior, Firestone, BFGoodrich, and Michelin offerings, with blackwall, wide whitewall, and double-whitewall presentations across series such as Comp H, Firestone Classic Bias Ply, Silvertown Classic Bias Ply, and Double Rivet. That gives owners room to choose a more understated touring look or a stronger restoration-oriented sidewall treatment.
Tire fitment for the covered 1932 Studebaker 55 Series sub-models is straightforward. The main point is confirming the car falls within the 6 Cyl. configuration, then choosing among the available 550-18 bias-ply tires based on appearance and wheel compatibility.

1932 Studebaker 55 Series 6 Cyl.
The 1932 Studebaker 55 Series 6 Cyl. uses the same 550-18 bias-ply tire that defines this vehicle line's primary fitment. That keeps tire selection focused on sidewall style, brand, and restoration presentation rather than sorting through multiple primary sizes.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Available 550-18 choices span Excelsior, Firestone, BFGoodrich, and Michelin, with series differences and sidewall options that include blackwall, wide whitewall, and double-whitewall. Rim-width specifications also vary, so product comparison should balance appearance with the wheel actually on the car.
Owners of a 1932 Studebaker 55 Series usually want clarity on 550-18 fitment, 18-inch rims, period-style sidewall choices, and what to inspect before putting a seldom-driven collector car back on the road.
Tire Size & Fitment
What tire size fits a 1932 Studebaker 55 Series?
The 1932 Studebaker 55 Series uses a 550-18 tire size. This is a numeric bias-ply size mounted on an 18-inch rim, and the covered 6 Cyl. sub-model uses that same primary fitment.
That makes the main decision less about sorting through multiple sizes and more about choosing the right 550-18 tire for the car's setup and appearance. Sidewall treatment, tire series, and wheel-width compatibility become the next checks, especially if the car has been restored with replacement wheels or has sat for long periods.
What size rim does a 1932 Studebaker 55 Series use?
The primary tire fitment for the 1932 Studebaker 55 Series is built around an 18-inch rim. The 550-18 size uses that 18-inch wheel diameter, which is the critical wheel measurement to confirm before selecting tires.
Wheel diameter is only part of the picture on a vintage car. Product options in 550-18 can call for different rim-width ranges, so it is worth checking the actual wheel on the car before choosing among available tires. That matters even more if the wheels were replaced during restoration or if the car no longer carries its original-style rims.
What does 550-18 mean on a 1932 Studebaker 55 Series?
On a 1932 Studebaker 55 Series, 550-18 is a vintage numeric bias-ply tire size. The 550 refers to an approximate 5.50-inch nominal section width, while the 18 identifies the wheel diameter in inches.
That older sizing format differs from modern metric radial sizing, so it helps to read it in period terms rather than trying to compare it casually to a current passenger-car size. Once the size is confirmed, the next step is choosing the sidewall style and tire line that best suits the car's restoration character, wheel width, and intended use.
Choosing the Right Tire
What should I consider when choosing a 550-18 tire for a 1932 Studebaker 55 Series?
Start with the correct primary size, which is 550-18, and confirm that the tire is a bias-ply design appropriate to the car's vintage fitment. From there, compare the actual wheel width on the car, since available 550-18 products do not all share the same rim-width specification.
Appearance is the next major decision. Some owners want a plain blackwall for a more restrained look, while others prefer wide whitewall or double-whitewall styling for a more formal restoration presentation. Brand, tire series, and details such as load figures where stated can also help narrow the choice without changing the original size format.
What sidewall styles are available for 1932 Studebaker 55 Series tires?
The 1932 Studebaker 55 Series has 550-18 tire options in blackwall, wide whitewall, and double-whitewall form. Those sidewall treatments give the car very different visual character even when the size and basic bias-ply construction stay the same.
A blackwall tire tends to suit a more understated or utilitarian presentation, while whitewall styles create a more formal period look often associated with restored pre-war cars. The right choice depends on how the Studebaker is being finished and shown. Sidewall style should be selected alongside brand, tire series, and wheel compatibility rather than by appearance alone.
What brands offer tires for the 1932 Studebaker 55 Series?
Available 550-18 tires for the 1932 Studebaker 55 Series come from Excelsior, Firestone, BFGoodrich, and Michelin. Those options span several vintage-style series, including Comp H, Firestone Classic Bias Ply, Silvertown Classic Bias Ply, and Double Rivet.
Brand choice is only one part of the decision. It should be weighed alongside sidewall style, rim-width specification, and the overall look you want the car to carry. Two tires can share the same 550-18 size yet still differ meaningfully in presentation and fitment details, so it helps to compare the full product characteristics before settling on one.
Restoration & Appearance
Which tire should I choose for a period-style 1932 Studebaker 55 Series?
A period-style starting point for a 1932 Studebaker 55 Series is a 550-18 bias-ply tire, since that keeps the car in its original-era sizing format and construction style. Within that size, the choice usually comes down to whether the car looks best with a blackwall, wide whitewall, or double-whitewall presentation.
The right answer depends on the character of the individual restoration rather than one universal rule. A restrained touring presentation may favor blackwall, while a more formal show-oriented finish may lean toward whitewall styling. When exact originality matters, marque references and vehicle-specific historical material are worth consulting before settling on a sidewall treatment.
Does correct tire fitment matter for a 1932 Studebaker 55 Series restoration?
Correct tire fitment matters because tire size and construction have a strong effect on how a 1932 Studebaker 55 Series sits, looks, and presents as an early 1930s automobile. Staying with the 550-18 bias-ply format preserves the proportions and visual language expected of the car.
Fitment also matters beyond appearance. The wheel must suit the tire's rim requirements, and the finished combination should clear the body and steering range properly. Even a well-restored Studebaker deserves those checks, particularly if the wheels were replaced, refinished, or altered at some point during the car's restoration life.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1932 Studebaker 55 Series?
Yes. A 1932 Studebaker 55 Series may still use the same 550-18 tire size in principle, but fitment can change if the car has replacement wheels, altered wheel width, brake conversions, suspension work, or body modifications that affect clearance.
Vintage cars often accumulate changes over decades, so it is smart to inspect what is actually on the car instead of assuming every 550-18 option will suit it the same way. Wheel diameter, wheel width, and steering or fender clearance should all be checked before mounting new tires, especially on a vehicle with an unknown restoration history.
What should I inspect before driving a 1932 Studebaker 55 Series on new tires?
Before road use, inspect the wheel condition, valve stems, bead seats, and overall mounting hardware, then confirm the tires are inflated properly for the chosen product and application. It also helps to check for even seating, adequate body and steering clearance, and any signs of rubbing at full lock.
A collector car deserves a broader inspection than the tires alone. Brakes, steering play, suspension condition, and wheel fastener security all matter before the first real drive. On an early 1930s Studebaker, that kind of pre-drive review is especially important if the car has been stored for a long time or recently returned to service.
How should 550-18 tires on a collector 1932 Studebaker 55 Series be maintained?
550-18 tires on a collector 1932 Studebaker 55 Series should be kept properly inflated, inspected regularly for cuts, cracking, bulges, and air loss, and protected from long exposure to heat, sunlight, moisture, and ozone sources. Occasional cleaning and routine pressure checks are especially important on low-mileage vintage cars.
Long storage can age a tire even when tread wear is minimal, so condition matters as much as miles traveled. It is also wise to look over the wheels and the way the car is sitting, since flat spotting, uneven loading, or poor storage surfaces can affect road behavior. Regular inspection keeps a seldom-driven Studebaker ready for safe, careful use.
