1933 Plymouth PD Tires

A 1933 Plymouth PD uses one of two primary bias-ply tire sizes: 5.25-17 or 600-16. Both sizes are correct to the model, but they are not interchangeable choices in the casual sense because each one is tied to a different rim diameter.

The practical step is to confirm the wheel diameter on the car before choosing a tire. A PD on 17-inch wheels needs the 5.25-17 path, while a PD on 16-inch wheels needs the 600-16 path. On an older car, wheel changes over the years are common, so the actual wheel setup matters more than assumption.

The 1933 Plymouth PD appears with two rim diameters in its tire fitment: 17-inch rims for 5.25-17 tires and 16-inch rims for 600-16 tires. Both fitments are bias-ply and both belong to the PD, so rim size is the deciding factor in choosing the tire size.

Checking the wheel itself is especially important on a pre-war car that may have seen replacement wheels or long-term restoration work. Measure or verify the rim diameter before ordering tires, and inspect wheel width and condition at the same time. That helps narrow the choice correctly before moving on to sidewall style or tire series.

The 1933 Plymouth PD Base follows the same overall fitment pattern as the model core, using either 5.25-17 or 600-16 bias-ply tires. That means the sub-model name alone does not settle the tire choice, because both sizes are associated with the Base configuration.

What matters next is the wheel diameter actually on the car. Once that is confirmed, the selection becomes much easier, especially with 600-16 where there is much more visible variety in brands, sidewall treatments, and tread character. The sub-model fitment is simple, but the wheel check still cannot be skipped.

A 600-16 tire for a 1933 Plymouth PD should first match the car's 16-inch wheel setup, then be chosen by the type of presentation and use the car is meant to have. This size is available in classic bias-ply form across passenger-style, military, and truck-oriented patterns, so the appearance and tread character can vary quite a bit.

Selection usually comes down to whether the car is being restored for a traditional passenger-car look or used in a way that calls for a more utilitarian tread style. Sidewall treatment also matters, since blackwall, wide whitewall, and double-whitewall options create very different visual results. Rim-width compatibility and overall wheel condition are worth reviewing before finalizing the choice.

For the 1933 Plymouth PD, the visible sidewall choices in 600-16 include blackwall, wide whitewall, and double-whitewall styles. Those options all stay within a bias-ply, pre-war-friendly tire presentation, but they change the car's visual character substantially from understated to more formal or more decorative.

A blackwall usually suits a simpler, more utilitarian appearance, while a wide whitewall brings a stronger vintage show-car feel. Double-whitewall designs offer another traditional look that stands apart from both. Since sidewall style is an appearance decision rather than a fitment shortcut, start with the correct rim diameter and tire size, then choose the look that matches the car's finish and restoration direction.

The 1933 Plymouth PD has 600-16 tire options from BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those brands appear across several bias-ply series, giving buyers a mix of traditional passenger-car styling and more specialized military or truck-style tread patterns.

Brand choice should be considered alongside the rest of the tire's character rather than by name alone. Compare the sidewall treatment, tire series, rim-width specification where stated, and the intended use of the car. On a vehicle like the PD, the right brand choice is usually the one that best matches the correct size, the wheel setup, and the visual direction of the restoration.

A period-style 1933 Plymouth PD starts with the correct bias-ply size for the wheel diameter on the car, either 5.25-17 or 600-16. From there, the best match depends on how traditional or formal the finished car is meant to look, especially if the car is being restored with strong attention to era-appropriate visual details.

For many owners, the appearance decision is shaped by sidewall style more than by the basic size itself. A blackwall can keep the look restrained, while a wide whitewall or double-whitewall creates a stronger pre-war visual statement. When absolute originality matters, compare the tire choice against marque references or period photos rather than assuming one sidewall treatment suits every restored PD.

On a restored 1933 Plymouth PD, bias-ply construction is central to the car's traditional tire profile and overall pre-war presentation. Since the PD's primary fitments here are bias-ply sizes, the construction itself plays a large role in preserving the kind of visual stance owners usually want from an early-1930s Plymouth.

Appearance is not shaped by construction alone, because sidewall design and tread style also influence the finished look. A classic passenger bias-ply gives a different impression than a military or truck-oriented bias-ply even in the same basic size. Matching construction to the car's restoration purpose helps the tire look intentional rather than simply serviceable.

Modifications can absolutely affect tire fitment on a 1933 Plymouth PD. If the car has replacement wheels, altered wheel width, suspension work, brake changes, or body modifications, those changes can influence which of the two primary tire sizes is appropriate and how much clearance is available.

An older car should always be checked as it sits today rather than judged by model name alone. Verify wheel diameter first, then look at wheel width, steering travel, and clearance around fenders and suspension components. That is especially important before moving into a wider-looking 600-16 product style or using a tread design with a different visual footprint.

Before driving a 1933 Plymouth PD on new tires, inspect the wheels for correct diameter, sound condition, and proper tire seating. It is also wise to check valve hardware, tube-related needs where applicable, wheel mounting surfaces, and overall clearance once the tires are installed and the car is on the ground.

Road readiness on a pre-war vehicle also depends on the rest of the chassis. Look over steering components, suspension wear, brake function, and alignment condition so the new tires are not being asked to compensate for other issues. After initial use, recheck inflation, fastener security, and any signs of rubbing or uneven contact.

Collector-car tires on a 1933 Plymouth PD should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the car uses 5.25-17 or 600-16 bias-ply tires, owners should watch for cracking, cuts, bulges, unusual wear, and any sign that the tire has been losing air while the car sits.

Low-use collector vehicles often age their tires by time and environment as much as by mileage. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the rubber, and occasional inspection of the contact patch can reveal flat-spotting or storage stress. A quick check before each outing is a good habit on any pre-war Plymouth.
