1964 Studebaker Wagons Tires

The 1964 Studebaker Wagons use 6.50-15, 670-15, and 600-15 tire sizes, all in bias-ply construction on 15-inch rims. The exact size depends on the wagon’s specific configuration, including sliding-roof versus non-sliding-roof body style and whether it is a 6-cylinder or 8-cylinder model.

That means the first job is matching the tire to the exact sub-model rather than assuming every 1964 Studebaker wagon uses the same size. A wagon that has had wheel changes over the years also deserves a quick measurement of the actual rim before ordering, especially if the goal is to keep a proper vintage stance and appearance.

The covered 1964 Studebaker Wagons tire sizes all use a 15-inch rim diameter. That applies across 6.50-15, 670-15, and 600-15 fitments, so the wheel diameter remains consistent even though the tire size itself can vary by sub-model.

Rim diameter is only part of the fitment picture on an older wagon. Wheel width should also be checked before selecting a tire, particularly if the car has replacement wheels or if a radial equivalent is being considered in place of a bias-ply size. Confirming both dimensions helps avoid clearance and proportion issues.

More than one tire size appears because the 1964 Studebaker Wagons line includes several sub-model configurations. Sliding-roof and non-sliding-roof wagons, along with 6-cylinder and 8-cylinder versions, do not all share the same primary size, even though they stay within 15-inch bias-ply fitment.

That makes sub-model identification the key step before comparing brands or sidewall styles. Once the correct size is established, the buying decision becomes much easier, because the remaining choices are about appearance, tire series, and whether to remain with a traditional bias-ply tire or consider an approved radial-equivalent size where one exists.

For the 1964 Studebaker Wagons, 670-15 is a primary bias-ply tire size. It uses the traditional numeric sizing system and appears as one of the wagon’s original-style fitments rather than as a modern radial format.

That matters because a buyer choosing 670-15 is usually deciding whether to keep the vintage bias-ply construction or move to a radial equivalent separately. The construction change affects more than appearance alone, so wheel width, overall dimensions, and clearance should be reviewed before making a switch, especially on a collector wagon that may no longer wear its original wheels.

Radial equivalents for 670-15 include 195R15 as an 80-series metric radial, P205/75R15 as a 75-series P-metric radial, P215/70R15 as a 70-series P-metric radial, and 670R15 as a bias-look radial. The recommended rim-width range attached to these equivalents is 5 to 7 inches.

Those options give different sizing formats rather than one automatic substitute. A bias-look radial keeps a more traditional visual impression, while the metric and P-metric choices follow modern radial sizing conventions. Before converting, compare the wagon’s actual wheel width and inspect steering, fender, and suspension clearance so the equivalent chosen suits the vehicle’s current setup.

Start with the original bias-ply size used on the wagon and match it only to an explicitly available radial equivalent for that size. Then confirm the wheel diameter, wheel width, and the recommended rim-width range attached to the equivalent being considered, such as 5 to 7 inches for 670-15 equivalents or 4 to 5 inches for 600-15 equivalents.

A conversion should also include a careful look at fender clearance, steering travel, and suspension condition, especially on a wagon that may have sat for long periods or been modified. Radial-equivalent sizing is a useful comparison tool, but the final choice still needs to suit the actual wheels and body clearances on the car in front of you.

The first consideration is making sure 670-15 is the correct size for the exact 1964 Studebaker wagon configuration. After that, the main differences come from construction style within the bias-ply category, available brands, sidewall treatment, tire series, rim-width specification, and product details such as load capacity and weight.

Some owners want a blackwall for a simpler utility look, while others prefer a narrow or wide whitewall for a stronger mid-century presentation. Because 670-15 has the widest assortment on this vehicle, it is also the size where comparing wheel compatibility and deciding between a traditional bias-ply tire and a radial-equivalent alternative becomes especially important.

The available sidewall styles for 1964 Studebaker Wagons tires include blackwall, narrow whitewall, and wide whitewall, depending on the tire size selected. The broadest variety appears in 670-15, while 600-15 has a more limited selection centered on blackwall and wide whitewall choices.

Sidewall style changes the wagon’s visual character more than many buyers expect, especially on a long-roof body where the tire is a prominent styling element. The right choice depends on whether the goal is a restrained utility look, a more upscale period-style appearance, or a restoration-oriented presentation that matches the way the vehicle is being finished.

Tires for the 1964 Studebaker Wagons are available from Firestone, BFGoodrich, US Royal, Coker Classic, Universal Vintage Tire, Excelsior, Avon, Goodyear, and STA, depending on the exact size. Most of the variety is concentrated in 670-15, while 600-15 has a narrower selection.

Brand choice should be considered alongside the size, sidewall style, and tire series rather than treated as the only decision. On a vintage wagon, a blackwall Firestone or Goodyear can create a different presentation from a wide-whitewall US Royal or BFGoodrich, even when the basic fitment is correct, so appearance goals still matter once size is settled.

A period-style 1964 Studebaker Wagons restoration starts with the correct primary bias-ply size for the exact sub-model, whether that is 6.50-15, 670-15, or 600-15. Once the proper size is confirmed, the visual direction usually comes down to blackwall versus whitewall and the character of the available classic tire series.

A wagon restored with a practical, understated look may suit blackwalls, while a more dressed presentation may point toward narrow or wide whitewalls. If exact originality matters beyond a general period-style approach, marque-specific historical references and restoration records are worth checking before settling on a brand or whitewall treatment.

Correct tire fitment matters on a 1964 Studebaker Wagons restoration because size, construction, and sidewall style all influence how the car sits and how authentic the finished presentation feels. Using the wrong primary size can change the visual balance of the wagon even before the car turns a wheel.

Fitment accuracy also helps keep the restoration practical, since the right 15-inch size and wheel relationship reduce the chance of avoidable clearance problems. Even when the goal is not concours judging, choosing the proper bias-ply size for the exact sub-model gives the restoration a more convincing vintage presence and a cleaner overall result.

Yes, modifications can affect tire fitment on a 1964 Studebaker Wagons even when the tire size itself is correct for the original application. Aftermarket wheels, changes in wheel width, altered ride height, suspension work, or body repairs can all influence how a bias-ply or radial-equivalent tire sits in the wheel opening.

An older wagon should be treated as an individual vehicle rather than as a fixed factory baseline. A quick check of actual wheel dimensions and visible clearances at the fender, steering components, and suspension can prevent surprises, especially if the car has changed hands several times or spent years off the road.

Before driving a 1964 Studebaker Wagons on new tires, inspect the wheels for correct diameter and condition, then verify that lug hardware, valve stems, and overall mounting condition are sound. The tires themselves should be checked for proper inflation, even seating, and adequate clearance at the fenders and steering components.

A collector wagon also benefits from a broader walk-around before road use. Look for suspension wear, brake issues, uneven stance, and anything that suggests the car has been sitting for a long time. A careful first inspection helps the new tires do their job without being asked to mask unrelated mechanical problems.

670-15 tires on a collector 1964 Studebaker Wagons should be maintained with regular pressure checks, periodic visual inspections, and clean, dry storage conditions. Watch for cracking, bulges, cuts, unusual wear, or air loss, since vintage vehicles often spend long periods parked and may age tires differently than a regularly driven car.

Storage habits matter almost as much as mileage on a collector vehicle. Keeping the wagon away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires between drives. It also makes sense to inspect the tires before any longer trip, since low annual use can hide age-related condition issues.
