1952 Studebaker Champion Tires

The 1952 Studebaker Champion uses a 640-15 tire size. This is a vintage numeric bias-ply fitment paired with a 15-inch wheel, and the covered Champion 6 Cyl. sub-model uses that same primary size.

For most owners, the question is less about choosing among multiple original sizes and more about selecting the right version of 640-15. Sidewall style, tire series, and whether to stay with bias-ply construction or evaluate a radial equivalent are the practical decisions, especially if the car has been fitted with different wheels over the years.

The 1952 Studebaker Champion uses a 15-inch rim with its primary 640-15 tire size. That rim diameter is central to both the original bias-ply fitment and any radial-equivalent size being considered.

Rim diameter alone is not the whole fitment story on an older car. It is also worth confirming the actual wheel width on the vehicle, especially if the car has replacement or aftermarket wheels, because the original bias-ply products and the radial equivalents do not all share the same rim-width guidance.

Yes. The 1952 Studebaker Champion 6 Cyl. uses the same 640-15 bias-ply tire size as the core fitment for this model. That keeps tire selection fairly simple at the sub-model level.

Because the size remains the same, the real comparison shifts to tire appearance and construction choice. A blackwall can give the car a more understated look, while narrow and wide whitewall options create a more restoration-oriented presentation, and any move to a radial equivalent still deserves a check of wheel width and vehicle clearance.

For the 1952 Studebaker Champion, 640-15 is the primary bias-ply tire size. That construction matches the vintage sizing system used on the car and preserves the traditional tire profile associated with early-1950s fitment.

Bias-ply and radial construction should not be treated as the same thing just because they can share a wheel diameter. Owners keeping a period-style look often stay with 640-15 bias-ply, while those considering a radial alternative should compare wheel width, tire dimensions, and clearance before making a change.

Radial equivalents for 640-15 include 175R15 as an 80-series metric radial, P175/75R15 as a 75-series P-metric radial, and P185/70R15 as a 70-series P-metric radial. A bias-look radial equivalent is not part of the available equivalent set for this size.

Those three alternatives give the 1952 Studebaker Champion owner different radial sizing conventions to compare rather than one automatic substitute. A 5- to 6-inch recommended rim-width range is tied to the equivalent group, so wheel width, overall tire dimensions, and clearance around suspension and bodywork should be confirmed before conversion.

Start by confirming the actual wheel diameter and wheel width on the car, then compare the available radial equivalents for the original 640-15 size. For this application, the equivalent group includes 175R15, P175/75R15, and P185/70R15, with a recommended rim-width range of 5 to 6 inches.

A conversion also deserves a close look at fender and steering clearance, suspension condition, and the car's overall setup. Older cars are often running replacement wheels, altered ride height, or worn steering components, and any of those factors can affect how a radial alternative behaves or whether it suits the vehicle cleanly.

Start with the correct primary size, which is 640-15, and then narrow the choice by construction, sidewall appearance, and wheel compatibility. Available products include bias-ply options from BFGoodrich, Firestone, Avon, and Excelsior, with blackwall, narrow whitewall, and wide whitewall styles.

The right choice depends on what the car is meant to do and how it should look. A restoration-oriented Champion may call for one whitewall treatment, while a more understated driver may suit blackwalls, and wheel width should still be checked because the listed 640-15 products do not all share exactly the same rim-width guidance.

The 1952 Studebaker Champion has 640-15 tire options in blackwall, narrow whitewall, and wide whitewall styles. That gives owners a meaningful appearance choice even while staying within the same primary tire size and bias-ply construction family.

Sidewall style can change the visual character of the car more than many buyers expect. A blackwall usually gives a simpler, plainer presentation, while narrow and wide whitewalls create a stronger early-1950s look, so the best match often comes down to the car's trim, restoration direction, and the owner's preference for subtle or more formal period styling.

Tires for the 1952 Studebaker Champion in the 640-15 size are available from BFGoodrich, Firestone, Avon, and Excelsior. Those brands cover several vintage-style bias-ply series and more than one sidewall presentation.

Brand choice should be considered alongside the details that actually affect selection, such as sidewall style, tire series, rim-width suitability, load specification, and the overall look you want on the car. Comparing those factors within the correct size usually tells an owner more than choosing by brand name alone.

A period-style 1952 Studebaker Champion starts with the original 640-15 bias-ply size on a 15-inch rim. Staying with that vintage numeric bias-ply fitment keeps the car in the proper size family and preserves the traditional sidewall shape associated with early-1950s American cars.

From there, the choice becomes more visual and use-specific. Blackwall, narrow whitewall, and wide whitewall versions all create different impressions, so owners concerned with exact authenticity should compare the car against marque references, period photographs, or restoration documentation rather than assuming every available sidewall treatment is equally appropriate.

Tire construction affects both the visual stance and the overall character of a restored 1952 Studebaker Champion. The original-size 640-15 bias-ply keeps the car in a traditional vintage construction, while radial equivalents move the car into a more modern sizing and construction approach.

That difference matters even before the car starts moving. Owners focused on a restoration-oriented presentation often prefer the look of a bias-ply in the original size family, while owners more interested in a driver may compare radial alternatives carefully, keeping in mind that wheel width, dimensions, and clearance still need to be verified before making the change.

Yes. Modifications can affect tire fitment on a 1952 Studebaker Champion even when the intended size remains 640-15 or one of its radial equivalents. Replacement wheels, different wheel widths, altered ride height, brake changes, or body and suspension work can all change the available space around the tire.

A car that has been lowered, fitted with aftermarket wheels, or rebuilt with non-stock components should be measured rather than assumed to match original clearance. Steering lock, inner fender space, and wheel width are especially important when moving away from the original bias-ply setup toward radial alternatives.

Before road use, inspect the wheels for damage, confirm the wheel diameter and width, and make sure the tires are seated correctly and inflated appropriately for the application. It is also smart to look over the valve stems, wheel hardware, and general clearance around suspension, fenders, and steering components.

On an older collector car, tire installation is only part of the readiness check. The Champion should also be examined for brake condition, steering play, worn suspension parts, and any signs that the body or chassis has shifted over time, since those issues can affect how the new tires track and clear under real driving conditions.

640-15 tires on a collector 1952 Studebaker Champion should be checked regularly for air loss, uneven wear, sidewall cracking, bulges, cuts, and signs of age-related deterioration. Collector cars often spend long periods parked, so tires can age and flat-spot even when tread wear appears minimal.

Good storage habits make a difference on a low-use car. Keeping the Champion away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and periodic inspection before each drive is wise because a vehicle that looks road-ready after storage can still have tire-related issues that deserve attention.
