Studebaker 8 Cyl. Tires

Studebaker 8 Cyl. applications in this group use two tire sizes for 1964: 6.50-15 and 670-15. Both are numeric bias-ply sizes built for 15-inch wheels. Product coverage shown here is centered on 670-15, with multiple bias-ply options in blackwall, narrow whitewall, and wide whitewall styles.

The practical difference is that a 1964 Studebaker 8 Cyl. owner should not assume one size fits every car from the year. Start by reading the size on the tire currently mounted, then compare that with the wheel width and any factory literature, build information, or restoration records for the specific car. That approach is especially important when more than one size appears within a single model year.

A 670-15 tire for a Studebaker 8 Cyl. uses the older numeric sizing system common on American bias-ply tires. The 670 indicates a nominal section width of about 6.70 inches, and the 15 indicates the wheel diameter in inches. The available 670-15 products here are bias-ply tires built for 15-inch rims, with many listed around a 4.50 to 5.00 inch rim width range.

That size code matters because it tells you both the width family and the wheel diameter, but it does not by itself confirm that every 1964 Studebaker 8 Cyl. used the same setup. Use the code as a fitment checkpoint, then verify the actual wheel on the car and compare the mounted tire’s proportions with the stance you want for restoration, touring, or show presentation.

A 1964 Studebaker 8 Cyl. has two listed tire sizes because the model group includes more than one fitment within the same year. Both sizes use the same 15-inch rim diameter and the same general bias-ply construction family, so the split is not a wheel-diameter change. It points instead to differences in configuration within the 1964 range, such as trim level or body style.

That means the year alone is not enough to choose a tire for a 1964 Studebaker 8 Cyl. owner who is trying to get the fit right. Check the car’s existing wheel and tire markings, compare the wheel width, and review any original sales literature, service information, or marque-club guidance tied to the specific car. Those details usually settle which of the two sizes belongs on a given example.

Studebaker 8 Cyl. tires in the listed sizes are bias-ply numeric fitments, and with this style of collector tire a tube is required. That applies to both 6.50-15 and 670-15 within this fitment group. The available products shown for 670-15 are all bias-ply constructions, which aligns with traditional tube-type use on period wheels.

Tube choice matters just as much as tire choice on a collector car because the wrong tube can create fitment or durability problems even when the outer tire size is correct. When replacing tires on a Studebaker 8 Cyl., match the tube to the tire size and wheel condition, and inspect the wheel carefully for rust, burrs, or damage that could affect sealing or tube life.

A 1964 Studebaker 8 Cyl. can use either 6.50-15 or 670-15, so the correct size starts with the individual car rather than the year alone. Both are 15-inch numeric bias-ply sizes, but they are not automatically interchangeable without checking the wheel and the original fitment intent for that specific configuration.

The best path is to inspect the sidewall of the tire currently on the car, measure or confirm the wheel width, and compare that information with original paperwork or trusted Studebaker references. If the car is being restored, decide whether originality, road manners, or visual stance is the top priority. That keeps the decision grounded in the actual car instead of relying on a broad year-only match.

Studebaker 8 Cyl. tires in the available 670-15 offerings come in blackwall, narrow whitewall, and wide whitewall styles. The whitewall widths vary, with several narrow 1-inch treatments and multiple wider period-style whitewalls also represented. That range gives owners room to match a plain, sporty, or more upscale mid-1960s appearance.

Sidewall style can change the character of a Studebaker 8 Cyl. as much as the size itself, especially on a restored car where period presentation matters. Blackwalls usually suit a more restrained look, while whitewalls can complement trim and brightwork. The right choice depends on how the car was originally equipped and how faithfully you want to follow its showroom-era appearance.

Studebaker 8 Cyl. tires in the available 670-15 size are offered by Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands span several period-style bias-ply families, from classic passenger-car lines to a truck-oriented option. The selection also includes multiple series names within certain brands.

Brand choice on a Studebaker 8 Cyl. usually comes down to the look you want, the sidewall style you prefer, and whether you are restoring a passenger-car presentation or considering a more utility-oriented tire. Owners building a judged restoration often start with visual correctness, while drivers focused on era-appropriate road use may compare sidewall style, load rating, and overall appearance more closely.

Studebaker 8 Cyl. offerings in 670-15 include series such as Firestone Classic Bias Ply, US Royal Classic Bias Ply, Coker Classic Bias Ply, Universal Classic Bias Ply, Silvertown Classic Bias Ply, Excelsior Bias Ply, Turbospeed Mk4, Super Cushion, Custom Super Cushion, Super Cushion Deluxe, and Super Transport. Most are period-style passenger-car bias-ply lines, while Super Transport is oriented toward truck service. Turbospeed Mk4 stands apart as an Avon bias-ply series with its own branding and specification style.

Those series differences matter because a Studebaker 8 Cyl. owner may be balancing authenticity, visual style, and intended use. A classic passenger-car series usually makes the most sense for a stock restoration or normal collector driving, while the truck-family option should be considered carefully in relation to the car’s use and appearance. Compare the sidewall treatment and construction family first, then narrow the choice by the look you want on the finished car.

A Studebaker 8 Cyl. should be stored in a cool, dry, dark space with clean tires, proper inflation, and as little exposure to sunlight, electric motors, and ozone sources as possible. If the car will sit for long periods, move it occasionally or support it in a way that reduces flat-spotting stress on the tires. Bias-ply collector tires especially benefit from stable storage conditions.

Good storage habits preserve more than tread life on a Studebaker 8 Cyl.; they also help protect sidewalls, casing shape, and the overall appearance that matters on a restored car. Keep oil, solvent, and fuel away from the rubber, and avoid letting one section of the tire carry the full vehicle load for months at a time. That simple routine can materially extend service life on a low-use collector car.

Tires on a Studebaker 8 Cyl. should be inspected before regular road use and again after any long storage period. On a collector car that sees occasional driving, a close visual check at least every few months is a sensible baseline. Look for cracking, weathering, uneven wear, bulges, punctures, and any signs that the tube or bead area may be causing trouble.

Inspection is especially important on a Studebaker 8 Cyl. because age and storage conditions can matter as much as mileage. Also check inflation pressure, valve stems, and the wheel itself, since a clean tire can still be unsafe if the tube, rim, or mounting surface is compromised. A collector car that appears fine parked in the garage can reveal problems only when it is prepared carefully for use.

A Studebaker 8 Cyl. tire should be replaced when age, cracking, hardening, sidewall damage, flat spotting that does not recover, or any structural concern appears, even if tread depth still looks generous. Collector tires often age out before they wear out. That is particularly true on low-mileage hobby cars where appearance can hide internal deterioration.

The practical rule for a Studebaker 8 Cyl. owner is to judge tires by condition and age, not just by remaining tread. If the car has sat for years, or if the rubber has become stiff and weathered, replacement is usually the wiser path. A specialist inspection is worthwhile whenever there is doubt, because age-related tire failure on a heavy V8-era collector car can be costly and dangerous.

Studebaker 8 Cyl. fitment in this group points to 6.50-15 and 670-15 as the relevant period sizes for 1964. The currently available products shown here are concentrated in 670-15 and are all period-style bias-ply offerings from several brands and series. That tells a restorer the car belongs in the traditional 15-inch bias-ply world rather than a later radial metric format.

Pinning down the exact original tire for a specific Studebaker 8 Cyl. still depends on the individual car’s configuration and restoration goal. A factory-authentic restoration should be checked against original literature, surviving examples, and Studebaker club guidance, especially when two sizes appear in the same model year. Once the correct size is confirmed, sidewall style becomes the next major authenticity decision.

Correct tire fitment can absolutely affect how a Studebaker 8 Cyl. is judged and how credible the restoration appears to knowledgeable enthusiasts. Size, sidewall style, and overall period character are all visible details that can change the car’s stance and historical presentation. On a collector car from the 1960s, those details are often noticed quickly.

For a Studebaker 8 Cyl. owner pursuing concours points or top-tier show presentation, the right approach is to match the tire size and sidewall treatment to the car’s specific configuration and era. Marque clubs and surviving original cars are often the best references for what looks right. Even outside formal judging, proper tire fitment supports the kind of authentic appearance that usually helps long-term collector appeal.

Studebaker 8 Cyl. tire offerings in 670-15 include blackwall, narrow whitewall, and wide whitewall choices, so more than one period-appropriate appearance is possible. That reflects the way mid-1960s American cars could vary in visual presentation depending on trim and equipment. A plain blackwall and a prominent whitewall can both look historically believable in the right context.

The correct sidewall style for a Studebaker 8 Cyl. restoration depends on how the individual car was equipped when new and how accurately the owner wants to replicate that look. Sales brochures, original photos, and marque-specific restoration guides are especially useful here. Once the proper size is established, selecting the right sidewall style is often what makes the finished car look truly sorted rather than merely close.

A properly selected, properly mounted Studebaker 8 Cyl. tire can be suitable for normal collector-car road use when the tire, tube, wheel, brakes, steering, and suspension are all in sound condition. The available options here are bias-ply designs, so they should be used with the expectations that come with period tire construction. They are not modern performance radials and should be treated accordingly.

For a Studebaker 8 Cyl., safety depends on the whole car rather than the tire alone. Before regular road driving, verify the correct size, inspect for age or storage damage, and make sure the chassis is aligned and mechanically healthy. A well-sorted collector car on fresh, correctly fitted bias-ply tires can be enjoyable on the road, but it should still be driven with period-appropriate caution.

Before driving a Studebaker 8 Cyl., check tire inflation, sidewall condition, tread condition, valve stems, wheel security, and any signs of tube-related leakage or bead trouble. Also look for uneven wear that might suggest alignment or suspension issues. On a collector car, those basic checks are often more important than mileage because long periods of inactivity can create problems that are not obvious at first glance.

The next step is to consider the car as a system. A Studebaker 8 Cyl. should have sound brakes, steering response, and suspension condition before any road trip, since even a correct tire cannot compensate for worn chassis parts. If the car has been parked for a season or longer, a short local shakedown drive after inspection is usually wiser than immediately heading onto faster roads.

A Studebaker 8 Cyl. running original-type bias-ply tires should be driven at moderate, sensible speeds that respect both the tire construction and the age of the vehicle itself. Even when a bias-ply tire is new, it does not deliver the same feel, tracking, or heat tolerance as a modern radial. That makes conservative cruising a better match for the way the car was designed to operate.

In practice, a Studebaker 8 Cyl. owner should build speed gradually, watch how the car feels, and avoid pushing the car as though it were equipped with modern touring tires. Steering corrections, braking distances, and ride behavior can all be different on bias-ply construction. The goal is steady, controlled collector-car driving rather than sustained high-speed use, especially on older roads or in hot weather.
