The 1949 Studebaker Commander arrived in the immediate postwar years, when American cars balanced fresh styling with practical everyday road manners. Studebaker stood apart from many larger manufacturers by giving its cars a distinct look and a loyal following that still matters to restorers and collectors today. For this exact model, the primary fitment is a 6.50-15 bias-ply tire on a 15-inch rim, which keeps the vehicle in its original-era sizing language. That makes tire choice less about sorting through multiple fitments and more about selecting the right period-style construction and appearance for the way the car will be used. For restoration-minded owners, wheel condition, overall stance, and road-readiness checks matter just as much as the size itself.
Which Tire Size Is Right for The 1949 Studebaker Commander
The 1949 Studebaker Commander uses one primary tire size: 6.50-15 in bias-ply construction on a 15-inch rim. The same fitment applies to the covered Commander 16A 6 Cyl. sub-model, so the main decision is choosing the right period-style tire within that size and confirming that the car still retains the correct wheel setup before installation.
A 6.50-15 tire uses a vintage numeric bias-ply size format, where 6.50 refers to the nominal section width in inches and 15 identifies the rim diameter. On a 1949 Studebaker Commander, this sizing keeps the car in the construction style and visual language typical of the late 1940s. Buyers looking at this size are usually balancing period-style appearance, ride character, and restoration goals rather than choosing among different modern fitment systems. It is also important to confirm that the car still has proper 15-inch wheels and enough overall clearance if wheel or suspension changes were made at some point in its life.
Sub-model fitment is straightforward for the covered 1949 Studebaker Commander application. The Commander 16A 6 Cyl. uses the same primary tire size, which simplifies selection as long as the car still carries the correct 15-inch wheel setup.

Frequently Asked Questions
These FAQs focus on the 1949 Studebaker Commander’s 6.50-15 tire fitment, 15-inch rim requirement, period-style selection concerns, and the maintenance checks that matter before a collector car returns to regular road use.
Tire Size & Fitment
What tire size fits a 1949 Studebaker Commander?
The 1949 Studebaker Commander uses a 6.50-15 tire size in bias-ply construction. That is the primary fitment for this application and it uses a 15-inch rim, which places the car firmly in a traditional postwar sizing format rather than a modern metric or P-metric system.
Using the correct size starts with confirming that the car still has 15-inch wheels and has not been changed to a different wheel diameter over the years. On an older collector car, it is also smart to inspect fender clearance, suspension height, and wheel condition before replacing tires, especially if the vehicle has seen restoration work or modifications.
What size rim does a 1949 Studebaker Commander use?
The 1949 Studebaker Commander uses a 15-inch rim with its 6.50-15 tire size. Rim diameter is the key wheel dimension tied directly to this tire size, and it needs to match correctly before any replacement tire is considered.
A 15-inch tire should only be mounted on the proper 15-inch wheel, so verifying the wheel diameter on the car itself is an important first step. Older vehicles are often changed during long ownership, and mismatched wheels can complicate tire selection quickly. Checking wheel width and general wheel condition is also worthwhile before putting a restored or long-stored car back into service.
Does the 1949 Studebaker Commander 16A 6 Cyl. use the same tire size?
Yes. The 1949 Studebaker Commander 16A 6 Cyl. uses the same 6.50-15 bias-ply tire size as the covered Commander fitment. That keeps the size question simple and avoids the need to sort between multiple primary tire sizes for this specific sub-model.
Even with shared fitment, it still helps to verify what is actually on the car today. Collector cars can pick up replacement wheels, altered ride height, or mixed tire sets over time. Confirming wheel diameter, checking for rubbing at full steering lock, and inspecting the condition of wheels and suspension components will help avoid problems once the new tires are mounted.
Choosing the Right Tire
What should I consider when choosing a 6.50-15 tire for a 1949 Studebaker Commander?
Start with the fundamentals: the tire should be a 6.50-15 and it should suit the Commander’s bias-ply fitment. For most buyers, the choice then becomes one of appearance and intended use, especially if the car is being restored, preserved as a collector vehicle, or prepared for occasional road driving.
A period-style presentation often matters as much as the size on a late-1940s car, so it helps to think about overall stance and how authentic-looking the finished car should appear. It is also worth checking that the wheels are sound, properly sized, and free of damage. On an older vehicle, a careful fitment decision always includes the condition of the car, not just the tire label.
How do I choose between the available 6.50-15 tires for a 1949 Studebaker Commander?
Choosing between 6.50-15 tires for a 1949 Studebaker Commander comes down to selecting a tire that matches the car’s vintage character and the owner’s goals for use. Since the size itself is already established, the real comparison is usually centered on how period-style the tire looks and how closely it suits the car’s restoration direction.
A Commander intended for show presentation may call for a different visual approach than one driven more regularly on local roads. Tire construction style, sidewall appearance, and compatibility with the car’s existing wheels should all be reviewed before making the final choice. It also helps to compare the condition of the rest of the chassis, because weak suspension or worn steering parts can affect how any new tire feels.
Why is the 6.50-15 size important on a 1949 Studebaker Commander?
The 6.50-15 size matters because it is the primary tire fitment for the 1949 Studebaker Commander and it preserves the vehicle’s intended wheel-to-tire relationship. On a postwar car like this, the tire size plays a major role in stance, visual balance, and the traditional driving character associated with bias-ply construction.
Moving away from the established size without careful checking can affect more than appearance. Wheel compatibility, body clearance, and the way the car sits can all change if the setup has been altered. That is why tire selection on an older Studebaker should begin with confirming the actual wheel diameter on the car and making sure the rest of the setup still supports the proper fitment.
Restoration & Appearance
Which tire should I choose for a period-style 1949 Studebaker Commander?
For a period-style 1949 Studebaker Commander, the best starting point is the original-era fitment format: a 6.50-15 bias-ply tire on a 15-inch rim. That keeps the car aligned with the sizing and construction style associated with late-1940s American passenger cars and supports a traditional overall presentation.
Appearance decisions on a restoration should be made with the whole car in mind, including wheel finish, ride height, and how authentic the final stance should look. If exact originality is important, marque literature, period photography, and restoration references can help narrow down the most appropriate visual treatment. The tire should complement the vehicle rather than simply fill the wheel opening.
Does correct tire fitment matter for a 1949 Studebaker Commander restoration?
Yes, correct tire fitment matters on a 1949 Studebaker Commander restoration because the tire has a strong effect on both appearance and overall presentation. A 6.50-15 bias-ply fitment keeps the car in the proper vintage sizing language and helps maintain the proportions expected on a late-1940s Studebaker.
Fitment also matters mechanically, not just visually. An older car with the wrong wheel diameter, questionable wheel condition, or altered suspension can end up with clearance issues or an awkward stance even when the tire itself is appropriate in size. Taking time to confirm the wheel setup and inspect the car before final assembly usually leads to a more convincing and roadworthy restoration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1949 Studebaker Commander?
Yes. Modifications can affect tire fitment on a 1949 Studebaker Commander even when the intended tire size remains 6.50-15. Changes to wheel diameter, wheel width, suspension height, steering components, or body clearances can all influence whether the tire sits and operates as expected on the car.
A Commander that has been lowered, fitted with aftermarket wheels, or rebuilt with non-original suspension parts deserves a closer inspection before new tires are mounted. Turning clearance, fender clearance, and the condition of the steering and suspension should all be checked. On a collector car with a long service history, assuming the setup is still stock can lead to avoidable fitment problems.
What should I inspect before driving a 1949 Studebaker Commander on new tires?
Before driving a 1949 Studebaker Commander on new tires, inspect the wheels, lug hardware, valve stems, steering components, suspension parts, and overall tire clearance. It also helps to check for fluid leaks that could reach the tires or brakes, along with any obvious issues that might affect safe road manners after the car has been parked or restored.
A careful walk-around should include tire pressure, tread area inspection, and a look for cuts, bulges, or sidewall damage if the car has been sitting for a long period during the installation process. Once the vehicle is moving again, pay attention to pull, vibration, or rubbing. Those signs can point to wheel, alignment, or clearance issues that should be addressed early.
How should 6.50-15 tires on a collector 1949 Studebaker Commander be maintained?
6.50-15 tires on a collector 1949 Studebaker Commander should be maintained with regular pressure checks, routine visual inspections, and attention to storage conditions. Because collector cars are often driven less frequently, tire condition can change with age and inactivity even when tread wear appears minimal.
Inspect the sidewalls for cracking, look for flat spotting after long storage, and watch for slow air loss before each outing. Clean, dry storage away from prolonged sunlight, heat, and ozone sources can help protect the tires over time. It is also wise to examine the wheels and suspension periodically, since an older vehicle’s roadworthiness depends on the entire assembly, not the tires alone.
