1933 Plymouth PC Tires

The 1933 Plymouth PC uses two primary tire sizes: 5.25-17 and 600-16. Both are bias-ply sizes, and the difference between them is tied to wheel diameter, with one fitting a 17-inch rim and the other fitting a 16-inch rim.

The practical choice starts with the wheels actually on the car, not just the model name on the title. A Plymouth that has been restored, repaired, or modified over the years may no longer wear its earlier wheel setup, so checking the rim diameter on the vehicle is the safest way to narrow the tire search before comparing appearance and tire series.

A 1933 Plymouth PC can use either a 17-inch rim or a 16-inch rim, depending on which primary tire size is on the car. The 5.25-17 tire matches a 17-inch rim, while the 600-16 tire matches a 16-inch rim.

That distinction matters because the two tire sizes are not simply alternate labels for the same wheel. Measuring the existing wheel or confirming the stamping on the rim helps avoid ordering the wrong size, especially on a pre-war car that may have changed wheels during decades of service, restoration work, or parts replacement.

The 1933 Plymouth PC appears with two primary bias-ply sizes because it is associated with two different wheel diameters. One setup uses 5.25-17 on a 17-inch rim, while the other uses 600-16 on a 16-inch rim.

For a buyer, that means the important question is not which size sounds more correct in general, but which wheel setup is actually on the car today. Once that is confirmed, the tire decision becomes much easier and can shift toward tread style, sidewall treatment, and whether the goal is road use, restoration presentation, or a combination of both.

Start with the basics: the car must have 16-inch wheels, and the tire should remain a bias-ply design to match the primary fitment. From there, 600-16 opens up the broadest selection, with different brands, tire series, sidewall styles, rim-width specifications, load figures, and tread presentations.

A restoration-focused car may lean toward traditional blackwall or whitewall styling, while a more specialized build may call for a different tread character. It also helps to compare rim-width guidance where shown, especially on an older vehicle that could be using replacement wheels rather than its earlier setup. Those details shape both appearance and compatibility.

The strongest sidewall variety appears in 600-16, where blackwall, wide whitewall, and double-whitewall options are available. That gives a 1933 Plymouth PC owner room to shape the car’s visual presentation without changing the basic vintage bias-ply construction.

Sidewall style affects the personality of the car as much as the tire brand does. A blackwall tends to keep the look restrained and utilitarian, while a wide whitewall or double-whitewall creates a more dressed, restoration-oriented appearance. The right choice depends on how the Plymouth is finished and whether the goal is understated authenticity or a more decorative period-style treatment.

For 600-16 fitment, the available brands include BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those options span several bias-ply series and include both traditional passenger-car styles and more specialized tread patterns.

Brand choice should come after size and wheel diameter are confirmed. Once the car is narrowed to 600-16, the useful comparison points become sidewall style, rim-width guidance where shown, load figures where stated, and whether the tire’s overall look suits a stock-style restoration, a driver-quality car, or a more specialized pre-war presentation.

A period-style 1933 Plymouth PC should start with the correct primary bias-ply size for the wheels on the car, either 5.25-17 or 600-16. That keeps the construction and overall visual character in step with the era, which is usually a major part of a pre-war Plymouth’s appeal.

After the size is settled, appearance becomes the real decision. A blackwall can suit a simpler, workmanlike presentation, while wide whitewall or double-whitewall options create a more formal restoration look. If exact originality matters down to sidewall treatment or brand style, marque-specific references and period vehicle documentation are worth consulting before making the final choice.

On a restored 1933 Plymouth PC, bias-ply construction plays a big role in preserving the visual character associated with an early 1930s automobile. The profile, stance, and overall presentation look appropriate to the car’s age in a way that modern tire constructions often do not replicate.

Construction is only part of the appearance equation, though. Sidewall style, tread pattern, and the relationship between the tire and the wheel also influence how finished the car looks once it is on the ground. Keeping the size and construction aligned with the car’s actual wheel setup helps the Plymouth look settled rather than mismatched.

Yes, modifications can affect tire fitment on a 1933 Plymouth PC, especially if the car has replacement wheels, altered suspension height, brake changes, or body and fender work. Even on an older vehicle with a simple tire specification, those changes can alter wheel diameter, wheel width, and available clearance.

That is why the actual car should be inspected before choosing between 5.25-17 and 600-16. A pre-war Plymouth may have lived through many decades of repairs and parts substitutions, so it helps to verify wheel dimensions, steering clearance, and the tire-to-fender relationship rather than assuming the current setup still matches an earlier configuration.

Before driving a 1933 Plymouth PC on new tires, inspect the wheels for damage or heavy corrosion, confirm the tire size matches the rim diameter, and check that the tires seat properly and hold pressure. It is also wise to look over the valve stems, lug hardware, and general condition of the brake and suspension components.

A short test drive should be preceded by a clearance check with the steering turned and the car at normal ride height. Pre-war cars often spend long periods parked, so road readiness is not just about the new tires themselves. Checking for looseness, uneven ride height, and signs of rubbing helps catch problems early.

Tires on a collector-era 1933 Plymouth PC should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and air loss, and protected from long exposure to sun, heat, moisture, and ozone-producing equipment. Regular visual checks matter because older cars are often driven less frequently than modern vehicles.

Maintenance also includes watching how the tires sit on the car over time. Uneven wear, a tire that begins to lean, or a sudden change in steering feel can point to wheel, alignment, or suspension issues rather than a tire problem alone. Consistent inspections are especially important before seasonal drives or longer trips.
