1941 Plymouth P11 Tires

A 1941 Plymouth P11 uses either 600-16 or 650-16 tires, and both are bias-ply sizes for 16-inch rims. The 1941 Plymouth P11 6 Cyl. uses 600-16, while the 1941 Plymouth P11 6 Cyl. (7 Passenger) uses 650-16.

That means the first step is confirming the exact sub-model rather than choosing by appearance alone. Once the size is matched correctly, the remaining decision is usually between blackwall, wide whitewall, or other period-style presentations, along with the specific tire series that best suits the car’s restoration style and driving use.

The 1941 Plymouth P11 uses a 16-inch rim with both of its primary tire sizes. Whether the car takes 600-16 or 650-16, the wheel diameter stays the same, so the size difference is in the tire itself rather than a change to a different rim diameter.

Wheel diameter is only part of the fitment picture on an older Plymouth. Before choosing a tire, it is still important to confirm the actual wheel width on the car, especially if the wheels have been changed over the years, because the available 600-16 and 650-16 products do not all share the same rim-width guidance.

The 1941 Plymouth P11 has more than one tire size because the covered sub-models do not use the same fitment. The standard 6 Cyl. model uses 600-16, while the 6 Cyl. (7 Passenger) model uses 650-16, even though both remain bias-ply applications on 16-inch rims.

That difference makes sub-model identification the most important step before any purchase or restoration decision. A car that has been altered, stored for decades, or fitted with non-original wheels should be checked carefully, since matching the correct tire to the body configuration helps preserve proper stance, appearance, and clearance.

Start with the correct primary size for the exact car: 600-16 for the 1941 Plymouth P11 6 Cyl. and 650-16 for the 6 Cyl. (7 Passenger). From there, compare construction, sidewall style, tire series, and rim-width guidance within that size rather than assuming every 16-inch option serves the same purpose.

A restoration-oriented sedan may call for a traditional blackwall or wide whitewall look, while another owner may be more concerned with tread style or load capacity. Looking at the car’s wheel setup, intended road use, and desired visual presentation usually narrows the field more effectively than choosing by brand name alone.

1941 Plymouth P11 tires are available in several sidewall styles, including blackwall and wide whitewall in both 600-16 and 650-16. In 600-16, double-whitewall options are also available, giving that size an extra appearance choice for owners pursuing a more dressed-up prewar presentation.

Sidewall style mainly affects the car’s visual character rather than its basic fitment category, but it can change the whole impression of a restoration. Matching the sidewall look to the Plymouth’s trim level, finish, and intended period style usually creates a more cohesive result than choosing a whitewall width simply because it is available.

Tires for the 1941 Plymouth P11 are available from several brands, including BFGoodrich, Coker Classic, Firestone, Goodyear, Excelsior, Lester, Avon, Ford Script, STA, Camac, Garfield, and Tornel, depending on whether the car uses 600-16 or 650-16. Those brands cover both passenger-style and military or truck-style bias-ply offerings.

Brand choice should be considered alongside the actual tire series, sidewall treatment, and intended use of the car. A prewar Plymouth driven for show, local road use, or a more utility-focused setup may point toward very different tread styles, even when the overall size remains correct for the sub-model.

A period-style 1941 Plymouth P11 starts with the correct primary bias-ply size for the exact sub-model: 600-16 for the 6 Cyl. and 650-16 for the 6 Cyl. (7 Passenger). From there, traditional blackwall or wide whitewall options in classic bias-ply series usually provide the most appropriate visual starting point.

Appearance details matter on a prewar Plymouth because tire profile and sidewall treatment strongly affect the car’s stance. When exact originality matters, compare your car’s configuration with marque references, photos, or restoration documentation, then choose the tire presentation that supports the era-correct look you want without assuming every available style is historically exact.

Correct tire fitment matters a great deal on a 1941 Plymouth P11 because the car’s proportions, ride height, and overall visual balance depend on using the proper bias-ply size. Since the P11 uses two different primary sizes across its sub-models, restoration work should begin by matching the tire to the correct vehicle configuration.

Using the wrong size can change how the car sits and can make an otherwise careful restoration look off even before the Plymouth is driven. Once the basic fitment is correct, details such as blackwall versus whitewall and the selected tire series help fine-tune the finished appearance without changing the vehicle’s underlying period character.

Yes, modifications can affect tire fitment on a 1941 Plymouth P11 even when the tire size itself is correct for the sub-model. Changes to wheel width, wheel offset, suspension height, brake components, or body clearance can alter how a 600-16 or 650-16 tire sits and moves within the car’s available space.

That is especially important on older vehicles that may have had wheels swapped long ago. A Plymouth with aftermarket wheels, altered springs, or body repairs should be measured carefully before tire selection, because correct nominal size alone does not guarantee the same clearance at the fenders, steering range, or suspension travel.

Before driving a 1941 Plymouth P11 on new tires, inspect the wheels for damage, verify the rim diameter and width, and make sure the tire size matches the correct sub-model. It is also smart to check wheel hardware, valve stems or tubes where applicable, alignment condition, and visible suspension or steering wear.

A fresh set of tires cannot compensate for long-stored mechanical issues common to collector cars. Looking over for side-to-side clearance, confirming proper inflation, and checking that the brakes, wheel bearings, and steering respond normally on a short test drive helps protect both the new tires and the car itself.

Collector-car tires on a 1941 Plymouth P11 should be maintained with regular pressure checks, periodic visual inspections, and careful storage habits. Even when tread wear is low, bias-ply tires on an infrequently driven car should be watched for cracking, flat spotting, bulges, cuts, and gradual air loss over time.

Keeping the Plymouth out of prolonged sunlight, heat, moisture, and ozone exposure helps preserve the rubber between drives. Routine inspection matters just as much as mileage on a prewar car, because age, storage conditions, and long idle periods can affect tire condition long before the tread appears worn out.
