1961 Studebaker Silver Hawk Tires

The 1961 Studebaker Silver Hawk uses a 670-15 tire size in bias-ply construction. That size is the primary fitment for the covered Silver Hawk application and mounts on a 15-inch rim, making it the starting point for any period-style replacement or comparison against modern radial-equivalent options.

Once the size is confirmed, the real choice becomes how the tire should look and how the car will be used. A traditional bias-ply keeps the original-style format, while radial equivalents need a closer look at wheel width, overall dimensions, and clearance before changing away from the 670-15 setup.

The primary tire fitment for a 1961 Studebaker Silver Hawk is built around a 15-inch rim. That rim diameter is tied directly to the 670-15 tire size, with the final number in the size marking identifying the wheel diameter rather than the tire’s outside height.

Rim diameter is only one part of the fitment picture, so it is worth checking actual wheel width before choosing between available 670-15 products or moving toward a radial equivalent. Collector cars are often changed over time, and an aftermarket wheel can affect how comfortably a given tire works on the car.

Yes. The covered 1961 Studebaker Silver Hawk 8 Cyl. uses the same 670-15 bias-ply tire size as the main model fitment. That makes size selection straightforward, since the decision does not depend on sorting through multiple tire sizes for different covered Silver Hawk configurations.

With the size settled, attention can shift to appearance and driving goals. A blackwall tire gives the car a more understated look, while narrow and wide whitewalls change the visual character substantially. Owners considering a radial alternative should still verify wheel width and body clearance before changing construction.

For the 1961 Studebaker Silver Hawk, 670-15 is the primary bias-ply tire size. It uses a vintage numeric sizing system rather than a modern metric format, which is why it looks different from later radial markings such as 195R15 or P205/75R15.

That matters because construction affects both presentation and selection. Staying with bias-ply keeps the Silver Hawk in its original tire format and opens up a wide range of blackwall and whitewall choices. Changing to a radial-equivalent size calls for a closer look at wheel width, tire dimensions, and available clearance.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. Those options cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial that keeps a more traditional visual character than a typical modern radial size.

These sizes are useful comparison points rather than automatic replacements. The recommended rim-width range associated with the equivalents is 5 to 7 inches, so the actual wheel should be measured before conversion. Clearance at the fender, suspension, and steering range should also be checked on the car as it sits.

A 670R15 bias-look radial is available as an equivalent to the 670-15 used on the 1961 Studebaker Silver Hawk. That makes it an appealing option for owners who want a radial-format alternative while keeping a tire presentation that is closer to the car’s original-era visual character.

It should still be treated as a conversion rather than a guaranteed substitute. Checking the Silver Hawk’s actual wheel width is important, especially since the recommended rim-width range for the radial equivalents is 5 to 7 inches. Tire-to-fender and steering clearance deserve a careful look before changing construction.

Start with the correct primary size, 670-15, and then narrow the choice by construction, sidewall style, and wheel compatibility. For the 1961 Studebaker Silver Hawk, the main decision is whether to keep a traditional bias-ply tire and choose among blackwall, narrow whitewall, or wide whitewall versions.

Brand and tire series also shape the final choice, especially if the car is being restored to a certain visual tone or used regularly on the road. Rim-width specifications vary across products, so the actual wheel should be checked before settling on a tire. Load capacity and overall vehicle setup are worth reviewing as well.

The 670-15 tires available for a 1961 Studebaker Silver Hawk come in blackwall, narrow whitewall, and wide whitewall styles. That gives the car a broad range of visual possibilities, from a restrained and simple look to a brighter, more prominent whitewall presentation associated with many early 1960s American cars.

The right sidewall style depends on the character of the individual car rather than on fitment alone. A blackwall often suits a more understated driver look, while whitewalls lean more restoration-oriented. Since several whitewall widths appear in this size, owners can fine-tune the Silver Hawk’s appearance without changing the underlying tire size.

The 1961 Studebaker Silver Hawk’s 670-15 size is available from Firestone, BFGoodrich, US Royal, Goodyear, Universal Vintage Tire, Coker Classic, Excelsior, Avon, and STA. Those brands appear across several bias-ply series, giving owners a wide selection without moving away from the car’s primary tire size.

Choosing among brands should come down to the details that matter for the car: sidewall treatment, rim-width specification, load figure where stated, and the overall presentation you want on the Silver Hawk. Rather than treating brand alone as the deciding factor, compare the complete tire specification and appearance together.

A period-style starting point for a 1961 Studebaker Silver Hawk is the original-format 670-15 bias-ply tire. That size keeps the car in the vintage numeric system and is available in several traditional series and sidewall treatments, including blackwall, narrow whitewall, and wide whitewall versions.

The best visual match depends on how the individual car is being presented. Some Silver Hawks look right with a restrained blackwall, while others benefit from a whitewall that emphasizes the coupe’s early 1960s styling. When exact originality matters, marque references and vehicle-specific historical material are worth consulting before final selection.

Construction changes the visual character as much as the driving character. On a restored 1961 Studebaker Silver Hawk, a 670-15 bias-ply keeps the car in its original-era tire format, while a radial equivalent can alter the look through different sizing conventions and a more modern sidewall profile.

That is why many restoration-oriented owners start by deciding whether appearance or construction change is the main priority. A bias-look radial offers a middle ground, since it is meant to preserve more traditional styling cues than a typical modern metric radial. The final choice should still be checked against the car’s actual wheels and stance.

Yes. A 1961 Studebaker Silver Hawk may have the correct 15-inch wheel diameter yet still present fitment issues if wheel width, offset, ride height, suspension parts, or brake components have been changed over the years. That becomes especially important when considering a radial-equivalent alternative to the original 670-15 bias-ply size.

Even mild changes can alter clearance at the fender edge, inner wheelhouse, or steering range. A Silver Hawk with aftermarket wheels should have the wheel width measured before tire selection, and a modified suspension should be inspected at full lock and full compression. That extra check helps avoid surprises after installation.

Before road use, inspect the 1961 Studebaker Silver Hawk’s wheels for correct diameter, visible damage, and proper bead-seat condition, then confirm that the tires are mounted in the right size and inflated appropriately for their application. Lug hardware, valve stems, and overall tire seating should be checked carefully as part of the installation.

The car itself deserves the same attention. Steering and suspension wear, weak shocks, poor alignment, and old brake components can all affect how a fresh set of tires feels on the road. A short local test drive followed by a second visual inspection is a smart way to confirm clearance, pressure stability, and general behavior.

Collector-car tires such as 670-15 fitments on a 1961 Studebaker Silver Hawk benefit from regular inspection even when the car is driven only occasionally. Pressure should be checked routinely, and the sidewalls and tread should be examined for cracking, cuts, bulges, flat spotting, or signs of slow air loss before any meaningful drive.

Storage conditions matter almost as much as mileage. Keeping the Silver Hawk away from prolonged heat, direct sunlight, standing moisture, and ozone sources helps preserve tire condition over time. Moving the car periodically and inspecting the tires by age as well as tread depth is especially important on low-use collector vehicles.
