The 1931 Plymouth PA comes from the early years when Plymouth was building a reputation for practical, well-engineered transportation during a highly competitive Depression-era market. Cars of this period ride and look right only when their tires suit both the chassis and the era. The 1931 Plymouth PA uses a 475-19 bias-ply tire on a 19-inch rim, keeping the fitment firmly in traditional pre-war territory. Available choices center on the Goodyear Deluxe All-Weather line, with either a blackwall or a 2.875 inch wide whitewall presentation. For a driver, restorer, or collector, the key decision is preserving the proper period-style stance while confirming wheel condition before road use.
Which Tire Size Is Right for The 1931 Plymouth PA
The 1931 Plymouth PA uses one primary tire size: 475-19. It is a bias-ply fitment for a 19-inch rim, and the covered PA Base model uses that same size. That means the main decision is not choosing between multiple primary sizes, but selecting the right sidewall style and staying true to the original-style bias-ply construction that suits a pre-war Plymouth.
In a numeric bias-ply size like 475-19, the 475 refers to an approximate 4.75-inch nominal section width, while 19 identifies the wheel diameter in inches. This is a traditional bias-ply construction, which matches the kind of tire format the 1931 Plymouth PA was designed around. Within this size, the available Goodyear Deluxe All-Weather options focus on appearance, with both blackwall and wide whitewall versions. Choosing 475-19 keeps the vehicle in its proper fitment family, but it is still wise to confirm that the car retains the correct 19-inch wheels and suitable rim condition before installation.
Tire fitment for the covered 1931 Plymouth PA sub-models is straightforward. The PA Base uses the same primary tire size, so the focus stays on selecting the right bias-ply tire style rather than sorting through multiple fitment combinations.

1931 Plymouth PA Base
The 1931 Plymouth PA Base uses the same 475-19 bias-ply tire as the model core, keeping fitment simple around a 19-inch wheel. That lets the selection process focus on period-style presentation, such as blackwall versus wide whitewall, while keeping the original-style construction in place.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

These FAQs focus on 1931 Plymouth PA tire size, 19-inch rim fitment, bias-ply construction, sidewall appearance, and the practical checks that matter before a pre-war Plymouth returns to road use.
Tire Size & Fitment
What tire size fits a 1931 Plymouth PA?
The 1931 Plymouth PA uses a 475-19 tire size. This is a numeric bias-ply size mounted on a 19-inch rim, and it is the primary fitment for the covered vehicle. The PA Base uses that same size, so there is no separate primary size to sort through within the covered sub-model range.
That makes the next step more about confirming the wheels on the car than comparing multiple fitment sizes. A 1931 vehicle may have had wheels replaced over the years, so checking that the car still has the correct 19-inch rims and proper rim condition is just as important as choosing the tire itself.
What size rim does a 1931 Plymouth PA use?
The 1931 Plymouth PA uses a 19-inch rim with its 475-19 tire fitment. Available tires in this size are built around that wheel diameter, and the product options shown for this application use a 19-inch rim with a 3-inch rim width.
Wheel diameter needs to be confirmed before ordering because a pre-war car may no longer wear its original wheel setup. It also helps to inspect the rim for rust, damage, out-of-round condition, and bead-seat issues so the tire choice is matched with a wheel that is suitable for safe mounting and road use.
Does the 1931 Plymouth PA Base use the same tire size?
Yes. The 1931 Plymouth PA Base uses the same 475-19 bias-ply tire size as the model core. That keeps fitment straightforward and means the main choice is between available tire presentations within the same size rather than switching between different primary fitments.
Even with shared fitment, it still helps to verify the actual wheels on the car before making a selection. Collector vehicles can pick up wheel substitutions over time, and checking rim diameter, width, and overall wheel condition avoids choosing a tire that matches the catalog fitment but not the car’s present setup.
Choosing the Right Tire
What should I consider when choosing a 475-19 tire for a 1931 Plymouth PA?
Start with the correct 475-19 size and the proper bias-ply construction, since that is the fitment family the 1931 Plymouth PA was built around. From there, the main product choice is sidewall appearance within the Goodyear Deluxe All-Weather series, with blackwall and wide whitewall versions available for the same size.
Selection usually comes down to how the car is being presented. A driver focused on a more understated pre-war look may lean toward blackwall, while a restoration-oriented car may benefit visually from a wide whitewall. Wheel condition, intended use, and the look you want the Plymouth to carry should guide the final choice.
What sidewall styles are available for 1931 Plymouth PA tires?
For the 1931 Plymouth PA, 475-19 tires are available in both blackwall and wide whitewall form. The wide whitewall option in this fitment is offered as a 2.875 inch whitewall, giving buyers a distinctly different period-style presentation while staying within the same overall tire size and construction type.
Sidewall style has a major effect on how a pre-war car looks, even when the size does not change. A blackwall keeps the appearance simpler and more restrained, while a wide whitewall creates a brighter, more formal look. Matching the tire’s visual character to the car’s restoration goals usually matters as much as the fitment itself.
How do I choose between the available 475-19 tires for a 1931 Plymouth PA?
The available 475-19 choices for a 1931 Plymouth PA stay within the same Goodyear brand, Deluxe All-Weather series, bias-ply construction, 19-inch rim diameter, and 3-inch rim width. That means the most visible difference is the sidewall treatment rather than a change in size, construction family, or basic fitment role.
Since the core specifications stay consistent, focus on how the tire supports the vehicle’s intended use and visual direction. A car built around authenticity in general appearance may call for one sidewall style, while a regularly driven collector car may simply need the look the owner prefers. Wheel health and proper mounting still matter either way.
Restoration & Appearance
Which tire should I choose for a period-style 1931 Plymouth PA?
A period-style 1931 Plymouth PA should begin with the proper 475-19 bias-ply size, because that preserves the tire format and overall visual character expected on an early 1930s Plymouth. Within that size, the Goodyear Deluxe All-Weather line offers a traditional route, with the main visual choice being blackwall or wide whitewall.
For many restorations, the decision comes down to how formal or restrained the finished car should look. A wide whitewall creates a more dressed appearance, while blackwall keeps the presentation simpler. If exact originality matters beyond general period style, marque-specific documentation and restoration references are worth checking before finalizing the sidewall choice.
Does correct tire fitment matter for a 1931 Plymouth PA restoration?
Yes, correct tire fitment matters greatly on a 1931 Plymouth PA restoration. The 475-19 size affects the car’s stance, wheel proportion, and overall period presentation, and the proper bias-ply construction helps maintain the visual character expected of a pre-war Plymouth rather than giving it a noticeably more modern tire profile.
Appearance is only part of the issue. Correct fitment also supports proper wheel compatibility and helps avoid problems created by mismatched diameters or altered wheel setups. On an older restoration or a newly acquired car, confirming actual rim dimensions and general wheel condition is a smart step before mounting new tires intended to restore the car’s look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1931 Plymouth PA?
Yes, modifications can affect tire fitment on a 1931 Plymouth PA even though the primary size is straightforward. Changes such as replacement wheels, altered suspension height, brake conversions, or body repairs can shift the wheel and tire relationship enough that a correct 475-19 tire size on paper still deserves a physical fitment check.
The most important things to verify are actual wheel diameter, wheel width, and available clearance through steering travel and suspension movement. A car of this age may have accumulated changes over many decades, so the safest approach is to confirm the present setup before mounting tires rather than assuming every surviving Plymouth PA remains exactly stock.
What should I inspect before driving a 1931 Plymouth PA on new tires?
Before driving a 1931 Plymouth PA on new tires, inspect the wheels for rust, cracks, bent areas, and bead-seat condition, then confirm the tires are mounted and inflated properly. It also helps to check valve stems, lug hardware, steering response, and whether the tires clear fenders and suspension components through normal movement.
A pre-war car deserves a broader road-readiness check beyond the tires themselves. Brake function, wheel bearings, alignment condition, and suspension wear can all affect how the car behaves once new bias-ply tires are installed. A short local test drive followed by another inspection is a sensible way to catch rubbing, air loss, or hardware issues early.
How should 475-19 tires on a collector 1931 Plymouth PA be maintained?
475-19 tires on a collector 1931 Plymouth PA should be maintained with regular pressure checks, visual inspections, and careful storage habits. Watch for sidewall cracking, bulges, cuts, uneven wear, and signs of slow air loss, especially on a car that spends long periods parked and only sees occasional use.
Collector vehicles often age their tires through time and environment more than mileage. Keeping the Plymouth away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition, and moving the car periodically can reduce long-term stress in one contact area. Tires that look acceptable at a glance still deserve close inspection before road use.
