The 1947 Studebaker Commander arrived in the first full model year after World War II, when buyers wanted dependable transportation with fresh styling and a more modern look than many prewar carryovers. That makes tire selection especially important today, because the stance and road manners of a restored postwar sedan depend heavily on staying true to its original sizing approach. This exact 1947 Studebaker Commander uses a 6.50-15 bias-ply tire on a 15-inch rim. The real choice is usually within that vintage size itself, especially for owners balancing traditional appearance, restoration character, and actual road use. Before changing anything, confirm the wheel setup and decide whether preserving the bias-ply presentation is part of the goal.
Which Tire Size Is Right for The 1947 Studebaker Commander
The 1947 Studebaker Commander uses one primary tire size: 6.50-15. It is a bias-ply fitment on a 15-inch rim, and the covered Commander 6 Cyl. configuration follows that same sizing. Since the size itself is straightforward, the decision usually comes down to choosing the right vintage-style tire within 6.50-15 and confirming that the car still has the correct wheel setup before replacement.
A 6.50-15 is a numeric bias-ply size in which 6.50 refers to the tire's nominal section width in inches and 15 identifies the wheel diameter. On a 1947 Studebaker Commander, this format reflects the period sizing system used on many immediate postwar American cars and preserves the traditional tire profile associated with the car's original layout. Because this is a bias-ply application, buyers typically focus on maintaining the correct visual proportion and overall vintage character rather than converting to a modern sizing system. It is the right starting point for a restoration-oriented replacement, but the actual wheel and vehicle setup should still be checked before mounting new tires.
Tire fitment is straightforward for the covered 1947 Studebaker Commander sub-model. The Commander 6 Cyl. uses the same 6.50-15 bias-ply sizing, so the main task is confirming that the car still retains the proper 15-inch wheel setup.

Frequently Asked Questions
Owners of a 1947 Studebaker Commander usually want clarity on the 6.50-15 fitment, 15-inch rim compatibility, bias-ply construction, restoration appearance, and the inspection steps that matter before putting a collector-era car back on the road.
Tire Size & Fitment
What tire size fits a 1947 Studebaker Commander?
The 1947 Studebaker Commander uses a 6.50-15 tire. This is a numeric bias-ply size, and it is the primary fitment for the covered Commander application on a 15-inch wheel.
That means the first priority is staying with the correct 6.50-15 sizing rather than jumping to a modern size by appearance alone. Many collector cars have had wheel changes over the years, so it is smart to confirm the actual wheel diameter and overall setup on the car before replacing tires.
What size rim does a 1947 Studebaker Commander use?
The 1947 Studebaker Commander uses a 15-inch rim with its 6.50-15 tire fitment. The tire size itself points to a 15-inch wheel, which is consistent with the Commander's primary setup.
Wheel diameter is only part of the fitment picture, especially on a car that may have seen decades of service or restoration work. It helps to verify the actual wheels on the car, inspect their condition, and make sure the tire size, wheel width, and overall clearance still suit the vehicle as it sits today.
Does the 1947 Studebaker Commander 6 Cyl. use the same tire size?
Yes. The covered 1947 Studebaker Commander 6 Cyl. uses the same 6.50-15 bias-ply tire size. That keeps fitment simple within this application and avoids a separate size decision between covered Commander versions.
Even when the sub-model fitment is straightforward, it still makes sense to confirm the wheel setup before ordering or mounting tires. A car that has been modified, stored for a long time, or fitted with later replacement wheels can need a closer look before settling on a new set of 6.50-15 tires.
Choosing the Right Tire
What should I consider when choosing a 6.50-15 tire for a 1947 Studebaker Commander?
Start with the correct size and construction. A 1947 Studebaker Commander uses a 6.50-15 bias-ply tire, so the first decision is whether the goal is to maintain a traditional postwar appearance and driving character with that vintage-style format.
From there, focus on practical details such as wheel condition, actual wheel dimensions, intended use, and how restoration-oriented the car needs to look. A Commander used mainly for shows may call for a different emphasis than one driven regularly, but both should begin with the proper 6.50-15 fitment.
How do I choose between available 6.50-15 tires for a 1947 Studebaker Commander?
Selection within 6.50-15 usually comes down to the kind of presentation and use the car is meant to have. On a 1947 Studebaker Commander, buyers often weigh vintage styling, restoration goals, and how closely they want the tire to reflect the car's original-era look.
It helps to compare tire details carefully rather than assuming every 6.50-15 is the same in practical use. Check the wheel setup on the car, think about how often it will be driven, and choose a tire that suits both the vehicle's appearance and the way the car will actually be used.
Why is the correct 6.50-15 size important on a 1947 Studebaker Commander?
The 6.50-15 size matters because it is the established fitment for the 1947 Studebaker Commander and it plays a major role in the car's stance, proportion, and period presentation. Collector-era cars can look noticeably different when the tire size drifts away from the intended range.
Using the correct size also gives a consistent starting point when checking wheel fit, body clearance, and overall drivability. Even if the car appears to have enough room for something else, staying with the proper 6.50-15 format helps avoid unnecessary guesswork on a postwar restoration or driver.
Restoration & Appearance
Which tire should I choose for a period-style 1947 Studebaker Commander?
A period-style 1947 Studebaker Commander starts with the correct 6.50-15 bias-ply size. That sizing format matches the Commander’s postwar tire profile and is the most natural foundation for preserving the car’s traditional stance and visual character.
Exact originality can involve details beyond size alone, so owners pursuing a highly specific restoration should compare surviving examples, factory literature, or marque-club guidance before settling on final appearance details. For most restoration-oriented cars, though, staying with a 6.50-15 bias-ply layout is the right first step.
Does correct tire fitment matter for a 1947 Studebaker Commander restoration?
Yes, correct tire fitment matters a great deal on a 1947 Studebaker Commander restoration. Tire size and construction affect the car's visual balance, ride height impression, and overall authenticity of presentation, especially on a postwar American car where tire profile is easy to notice.
A restoration-minded owner should think about more than whether a tire simply mounts on the wheel. The right 6.50-15 bias-ply fitment helps keep the car's appearance in character, while wheel changes or mismatched modern sizing can alter the look enough to stand out on an otherwise well-finished Commander.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1947 Studebaker Commander?
Yes. Modifications can affect tire fitment on a 1947 Studebaker Commander even when the original size is straightforward. Changes to wheels, suspension height, brake components, or body clearance can all influence how a 6.50-15 tire sits and operates on the car.
That is why an older vehicle should be inspected as it exists today, not only as it left the factory. A Commander with replacement wheels or altered suspension may need extra attention to wheel dimensions, steering clearance, and overall stance before new tires are installed for regular road use.
What should I inspect before driving a 1947 Studebaker Commander on new tires?
Before driving a 1947 Studebaker Commander on new tires, inspect the wheels, valve hardware, lug hardware, and general suspension and steering condition. It also helps to confirm that the tires are seated properly, inflated correctly for the application, and free from any mounting or clearance concerns.
Collector cars often need a broader safety check before returning to the road. Look over wheel bearings, brake condition, alignment behavior, and any signs of rubbing once the car is on the ground. A short local test drive can reveal vibration, pull, or interference before a longer outing.
How should 6.50-15 tires on a collector 1947 Studebaker Commander be maintained?
6.50-15 tires on a collector 1947 Studebaker Commander should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is low, collector vehicles can develop tire issues from age, long periods of inactivity, heat, sunlight, or improper inflation.
Routine checks should include looking for sidewall cracking, bulges, cuts, uneven wear, and slow air loss. It also helps to keep the car stored in a clean, dry area away from ozone sources and to move or drive it occasionally so the tires are not left supporting the same load position for long periods.
