The 1940 Studebaker Champion arrived as a smart, efficient prewar American car, remembered for bringing streamlined styling and sensible engineering to a broad market. For many owners today, the appeal is in preserving that balanced character rather than over-tiring the car with a modern-looking replacement. The 1940 Studebaker Champion uses a 550-16 bias-ply tire on a 16-inch rim, keeping the fitment firmly in period. Within that size, choices include blackwall and wide whitewall presentations across several traditional bias-ply series and brands. The real decision is usually how closely the tire should match the car’s intended appearance and road use while staying compatible with the original wheel setup.
Which Tire Size Is Right for The 1940 Studebaker Champion
The 1940 Studebaker Champion uses one primary tire size: 550-16 in bias-ply construction on a 16-inch rim. That fitment carries across the covered Champion sub-model here, so the main choice is not between multiple sizes, but between blackwall or wide whitewall appearance, brand and series, and how closely the tire should support a restoration-minded look.
A 550-16 size uses a vintage numeric bias-ply format in which the 5.50 figure refers to the tire’s nominal section width in inches, and the 16 identifies the rim diameter. On a 1940 Studebaker Champion, that construction preserves the prewar tire profile and look that suit the car’s original-era character. Available choices in this size include Excelsior, Avon, BFGoodrich, and Firestone, with both blackwall and wide whitewall styles offered across traditional bias-ply series. Choosing within 550-16 comes down to wheel compatibility, appearance goals, and whether the car is being finished as a restrained driver or a more restoration-oriented presentation.
Fitment is straightforward for the covered 1940 Studebaker Champion sub-model. Tire size remains consistent here, so checking the sub-model mainly helps confirm that the car still uses the expected wheel and tire setup before selecting among available bias-ply options.

Tire Size & Fitment
What tire size fits a 1940 Studebaker Champion?
The 1940 Studebaker Champion uses a 550-16 tire size in bias-ply construction. That is the primary fitment for the covered Champion application and it matches a 16-inch rim, which places the car firmly in the prewar numeric bias-ply sizing system rather than later alphanumeric or modern metric sizing.
Knowing the size is only the first step, because many Champions have spent decades in storage or have seen wheel changes over time. Confirm that the car still has the correct 16-inch wheels, then compare the available 550-16 options by sidewall style, brand, and rim-width compatibility before settling on a tire for road use or restoration display.
What size rim does a 1940 Studebaker Champion use?
The 1940 Studebaker Champion uses a 16-inch rim with its 550-16 tire fitment. That rim diameter is central to the size itself, since the final number in 550-16 identifies the wheel diameter the tire is built to mount on.
Rim diameter should be confirmed on the actual car before any purchase, especially on an older vehicle that may have had wheel swaps during its life. A tire built for a 16-inch rim cannot be treated as suitable for another diameter, and rim width should also be checked so the chosen 550-16 tire matches the wheel it will actually run on.
Does the 1940 Studebaker Champion 6 Cyl. use the same tire size?
Yes. The covered 1940 Studebaker Champion 6 Cyl. uses the same 550-16 bias-ply tire size as the core 1940 Studebaker Champion fitment shown here. That keeps the fitment picture simple and avoids the sub-model size split that appears on some other vintage vehicles.
Even with shared fitment, the right tire can still vary by the car’s intended finish and use. A blackwall 550-16 gives a more restrained prewar look, while a wide whitewall changes the visual character noticeably, so it helps to decide whether the car is being prepared as a driver, a restoration-minded car, or a display-focused vehicle.
Choosing the Right Tire
What should I consider when choosing a 550-16 tire for a 1940 Studebaker Champion?
Start with the fundamentals: the 1940 Studebaker Champion uses a 550-16 bias-ply tire on a 16-inch rim, so the first job is staying within that fitment. After that, the main differences are brand, tire series, sidewall treatment, and whether the selected tire’s wheel-width range matches the wheels actually on the car.
Appearance often drives the final choice on a prewar Studebaker. A blackwall usually gives a simpler, more understated presentation, while a wide whitewall creates a stronger vintage visual statement. It is also worth checking product details such as load figures where shown, because a collector car that sees regular road miles may call for a different balance than one used mainly for shows.
What sidewall styles are available for 1940 Studebaker Champion tires?
The 1940 Studebaker Champion’s 550-16 tire choices include both blackwall and wide whitewall sidewall styles. Those options are available within traditional bias-ply offerings, so the change is primarily one of appearance rather than a switch to a different tire construction category.
Sidewall style has a major effect on how the car presents visually. Blackwall tires keep the look restrained and functional, while wide whitewalls give the Champion a brighter, more formal prewar character. Because the page already narrows the fitment to the correct size, the best next step is comparing sidewall style alongside brand, series, and wheel compatibility rather than treating appearance as the only factor.
What brands offer tires for the 1940 Studebaker Champion?
Available 550-16 tires for the 1940 Studebaker Champion come from Excelsior, Avon, BFGoodrich, and Firestone. Those brands appear across several traditional bias-ply lines, giving the buyer more than one route to the correct vintage size without changing the car’s basic fitment approach.
Brand choice is most useful when paired with the other visible differences in the product range. Some options emphasize a blackwall presentation, others offer wide whitewalls, and some include published rim-width or load details that may matter on the actual wheel setup. The stronger approach is to compare the whole tire package rather than assume the brand name alone answers the fitment question.
Restoration & Appearance
Which tire should I choose for a period-style 1940 Studebaker Champion?
A period-style 1940 Studebaker Champion should begin with the correct 550-16 bias-ply size, because that preserves the tire format and overall visual character appropriate to a prewar American passenger car. From there, the choice usually narrows to blackwall or wide whitewall, along with the brand and tire series that best suit the way the car is being presented.
For many restoration-minded owners, appearance matters nearly as much as fitment. A wide whitewall can create a stronger formal or show-oriented look, while a blackwall keeps the presentation simpler and more reserved. If exact originality is important, it helps to compare the tire choice against marque-club guidance, period photos, or other vehicle-specific historical references before finalizing the finish.
How does tire construction affect the appearance of a restored 1940 Studebaker Champion?
Tire construction affects a restored 1940 Studebaker Champion visually as well as mechanically. The correct primary fitment here is bias-ply, and that construction supports the tall, traditional prewar look buyers usually expect on a car from 1940, especially when paired with the right sidewall treatment.
On a restoration-oriented car, construction influences the overall impression from fender to wheel opening, not just the tread. Keeping the Champion on a bias-ply 550-16 helps maintain a traditional profile, while the choice between blackwall and wide whitewall further shapes the finished appearance. Matching tire style to the car’s trim level and intended presentation usually produces a more coherent result than choosing on brand name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1940 Studebaker Champion?
Yes. Even though the 1940 Studebaker Champion’s primary fitment is 550-16 on a 16-inch rim, modifications can change how safely and cleanly that size works on the actual car. Wheel swaps, altered rim width, suspension changes, brake conversions, or body work can all affect mounting compatibility and running clearance.
A vintage Studebaker often looks stock while hiding decades of changes, so inspection matters before mounting new tires. Check wheel diameter and width first, then look at steering clearance, fender clearance, and the condition of springs and suspension components. That extra verification is especially worthwhile on a car returning to the road after a long layup or partial restoration.
What should I inspect before driving a 1940 Studebaker Champion on new tires?
Before driving a 1940 Studebaker Champion on new tires, inspect the wheels, valve stems, lug hardware, and the overall condition of the suspension and steering. The car should also be checked for proper tire seating, adequate clearance at full steering travel, and any signs that old wheel damage or misalignment could affect how the new 550-16 tires run.
Collector cars often reveal problems only after fresh tires go on, because the new rubber highlights issues that tired old tires were masking. A short local test drive followed by another look for rubbing, air loss, or unusual wear is a smart step. It also helps to confirm inflation and make sure the spare, if carried, is in equally roadworthy condition.
How should 550-16 tires on a collector 1940 Studebaker Champion be maintained?
550-16 tires on a collector 1940 Studebaker Champion should be maintained with regular pressure checks, visual inspections, and careful storage habits. Bias-ply tires on low-mileage vintage cars deserve close attention for sidewall cracking, flat-spotting from long parking periods, tread damage, bulges, and slow air loss, even when the car appears to be used only lightly.
Good storage helps extend service life on a prewar car that spends more time parked than driving. Keep the Champion away from prolonged sunlight, excess heat, moisture, and ozone sources, and move the car periodically if it sits for long stretches. A tire that still looks presentable should not be assumed road-ready without checking age, condition, and how consistently it holds air.
