1955 Nash Statesman Tires

The 1955 Nash Statesman uses a 670-15 tire size. That is a vintage numeric bias-ply size mounted on a 15-inch rim, and it is the primary fitment for the covered Statesman application.

Because there is one main size to work with, the next decision is not which primary size fits but which version of 670-15 best matches the car. Sidewall style, tire series, and whether to stay with bias-ply construction or consider a radial equivalent become the important comparisons once the vehicle still has the expected wheel setup.

The primary tire fitment for a 1955 Nash Statesman is built around a 15-inch rim. That rim diameter matches the 670-15 sizing, where the final number identifies the wheel diameter in inches.

Rim diameter should be confirmed directly on the car before ordering tires, especially if the vehicle has been changed over the years. A 15-inch wheel can still vary in width, and that matters when comparing available 670-15 products or evaluating a radial equivalent that may call for a different wheel-width range than a traditional bias-ply tire.

Yes. The covered 1955 Nash Statesman 6 Cyl. uses the same 670-15 bias-ply tire size as the model-level fitment. That keeps the basic size question simple for this sub-model.

Since the size stays the same, selection comes down to tire presentation and intended use. A blackwall can give the car a more understated look, while narrow or wide whitewalls push it in a more restoration-oriented direction, and radial equivalents may appeal to owners who want an alternative construction after verifying wheel width and vehicle clearance.

For the 1955 Nash Statesman, 670-15 is the primary bias-ply tire size. That numeric format is part of the car’s traditional fitment and is the size around which the available classic tire choices are built.

That matters because a bias-ply 670-15 preserves the original-era sizing convention and appearance of the car. Buyers comparing alternatives should keep in mind that a radial equivalent is a separate choice rather than the same construction in a different label, so wheel width, clearance, and the car’s intended use should all be checked before changing direction.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. The first is an 80-series metric radial, the second is a 75-series P-metric radial, the third is a 70-series P-metric radial, and 670R15 is the bias-look radial alternative.

Those options give a 1955 Nash Statesman owner several ways to move from the original bias-ply size into radial construction without treating every option as the same. The recommended rim-width range for the equivalents is 5 to 7 inches, and the final choice should be checked against the wheel on the car, surrounding clearances, and the look the owner wants to maintain.

Start by confirming that the car still has 15-inch wheels and that the wheel width matches the radial size being considered. For the 670-15 fitment, radial equivalents include 195R15, P205/75R15, P215/70R15, and 670R15, with a recommended rim-width range of 5 to 7 inches.

The practical checks go beyond the size label. Steering clearance, fender clearance, suspension condition, and the actual wheel setup all matter when moving from bias-ply to radial construction, especially on an older car that may have seen wheel or suspension changes. That approach helps avoid assuming that an equivalent size will automatically suit every Statesman exactly the same way.

Begin with the confirmed primary fitment: 670-15 on a 15-inch wheel. From there, compare whether the goal is a traditional bias-ply tire, a sidewall style that matches the car’s intended appearance, and a product whose rim-width specification and load capacity suit the wheel and use of the vehicle.

A 1955 Nash Statesman can take on a noticeably different character depending on whether it wears blackwalls, narrow whitewalls, or wide whitewalls. Tire series and brand differences also matter when comparing visual style and specifications, so it helps to decide early whether the priority is restoration-minded presentation, general collector-car driving, or evaluating a radial-equivalent path.

In 670-15, the 1955 Nash Statesman has blackwall, narrow whitewall, and wide whitewall choices. Those sidewall treatments appear across multiple classic bias-ply offerings, so the size allows meaningful variation in how the car is presented without changing the primary fitment.

Sidewall style has a strong effect on the finished look of a mid-1950s sedan. Blackwalls tend to feel more restrained, narrow whitewalls split the difference, and wide whitewalls create a stronger period-style statement, so the right choice depends on whether the car is being preserved as a subtle driver or finished with a more restoration-oriented appearance.

The 670-15 size for a 1955 Nash Statesman is available from Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands appear across several bias-ply series and sidewall treatments rather than as one uniform type of product.

Brand choice should be weighed alongside construction, sidewall style, rim-width specification, and the intended look of the car. Some buyers focus on a particular classic tire series, while others are primarily choosing between blackwall and whitewall presentations, so the most useful comparison is usually the complete package rather than the brand name alone.

A 670-15 bias-ply tire is the period-style starting point for a 1955 Nash Statesman because it preserves the original-era sizing format and traditional construction associated with the car. Within that size, blackwall, narrow whitewall, and wide whitewall versions create very different visual impressions.

The best restoration-oriented choice depends on how closely the car is being finished and what historical look is being pursued. If exact originality matters, marque references, period photos, and vehicle-specific documentation are worth consulting before settling on a brand or whitewall width, since the right presentation is often more specific than size alone.

Tire construction changes more than ride feel on a restored 1955 Nash Statesman; it also changes the car’s visual character. A bias-ply 670-15 keeps the traditional vintage sizing language and complements a more authentic mid-1950s presentation, while a radial alternative can shift the look even if the wheel diameter stays the same.

That is why many restoration-minded owners decide on appearance before comparing product details. A bias-look radial can help bridge that gap for someone who wants radial construction without moving as far away from a traditional tire profile, but it still deserves the same checks for wheel width, clearance, and overall visual balance on the finished car.

Yes. A 1955 Nash Statesman may use the original 670-15 fitment, but aftermarket wheels, altered wheel width, suspension changes, or body and brake updates can all affect what works on the car. Even when the rim diameter remains 15 inches, the actual setup can differ from stock.

That matters most when choosing among products with different rim-width specifications or when considering a radial equivalent. The safest approach is to verify the wheel dimensions actually on the car and then check tire-to-fender and tire-to-steering clearance at full lock and through suspension travel rather than assuming every Statesman still matches its original configuration.

Before road use, inspect wheel condition, valve stems, lug hardware, tire pressure, and overall clearance around the new tires. On a collector-era car like a 1955 Nash Statesman, it also makes sense to look closely at suspension wear, steering components, and brake condition so the new tires are not being asked to compensate for other problems.

A short, careful test drive is a useful follow-up after installation. Listen for rubbing, check steering response, and recheck inflation once the tires have settled in service, especially if the car has sat for long periods or has had previous wheel changes. That routine helps confirm that the fitment works cleanly in real driving conditions.

670-15 tires on a collector 1955 Nash Statesman should be kept properly inflated, inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, and stored away from prolonged sunlight, heat, moisture, and ozone sources when the car is parked for long periods. Regular visual checks matter even if mileage stays low.

Collector cars often age their tires by time and storage conditions more than by tread wear. Rolling the car occasionally, keeping the suspension in sound condition, and checking the tires before each longer outing helps catch developing issues early. That is especially important on an older bias-ply setup, where condition and proper care are as important as the correct size.
