The 1931 Plymouth Export comes from the early Depression-era period when Plymouth was building its reputation on practical transportation with solid engineering and clean, conservative styling. Cars from this era depend heavily on proper tire proportions to preserve their stance, steering response, and overall period character. For this model, the primary fitment is a 500-19 bias-ply tire on a 19-inch rim. Available choices in that size include blackwall bias-ply options from Excelsior and Firestone, with differences in tire series and intended use. For a restoration-minded owner, the key decision is choosing a 500-19 that matches the car's appearance goals and the way it will actually be driven.
Which Tire Size Is Right for The 1931 Plymouth Export
The 1931 Plymouth Export uses one primary tire size: 500-19. That size is a bias-ply fitment for a 19-inch rim, and it carries across the covered sub-model here, so the main decision is not size selection but choosing the right 500-19 tire style and product type for restoration appearance, intended road use, and wheel compatibility.
The 500-19 size uses a vintage numeric bias-ply format in which the 500 refers to an approximate 5.00-inch nominal section width and the 19 identifies the rim diameter in inches. On a 1931 Plymouth Export, that keeps the tire in the period-style construction the car was built around. In this size, blackwall choices include the Excelsior Comp H series and the Firestone Dirt Track Ribbed Front, so selection can center on series character and rim-width compatibility. It is the size to evaluate when preserving an early 1930s look and maintaining the proper wheel diameter.
Fitment is straightforward for the covered 1931 Plymouth Export sub-model. The same primary tire size carries across the listed configuration, so checking the sub-model mainly confirms that the car remains on the expected wheel and tire setup before choosing among available 500-19 options.

Tire Size & Fitment
What tire size fits a 1931 Plymouth Export?
The 1931 Plymouth Export uses a 500-19 tire size. This is a bias-ply fitment, and the covered sub-model here uses that same size, so the starting point for replacement remains consistent across the vehicle page.
The practical step is confirming that the car still has its 19-inch wheels and has not been changed to a different wheel setup over the years. Once that is verified, the decision moves to comparing available 500-19 tires by series, rim-width suitability, and the type of use planned for the car.
What size rim does a 1931 Plymouth Export use?
The 1931 Plymouth Export uses a 19-inch rim with its 500-19 tire size. Product options in this fitment are also built around a 19-inch rim, which is the critical wheel diameter to confirm before choosing a replacement tire.
Rim diameter matters first, but wheel width still deserves a look because available 500-19 products can carry different rim-width specifications. A car that has been restored, repaired, or modified may not still be on its expected wheels, so checking the actual rim before purchase helps avoid unnecessary fitment issues.
Does the 1931 Plymouth Export Base use the same tire size?
Yes. The 1931 Plymouth Export Base uses the same 500-19 bias-ply tire size as the model core. That keeps fitment straightforward and means the buyer is comparing tire choices within one established vintage size rather than sorting through multiple primary sizes.
That consistency simplifies the search, but it is still worth checking the car's current wheel setup if it has had a long restoration history. A visual inspection of the wheel diameter, rim width, and overall tire clearance is especially useful on early vehicles where replacement wheels may have been installed at some point.
Choosing the Right Tire
What should I consider when choosing a 500-19 tire for a 1931 Plymouth Export?
Start with the correct 500-19 size and the bias-ply construction this Plymouth uses. From there, compare the tire series, the intended use of the tire, rim-width specifications, and any available load information so the tire choice matches both the wheel and the way the car will be driven.
Appearance also matters on a 1931 car because tire shape and sidewall presentation have a strong effect on the vehicle's stance. A restoration-oriented owner may focus on traditional blackwall presentation, while a buyer planning specialty use may pay closer attention to product character and wheel compatibility.
What brands offer tires for the 1931 Plymouth Export?
The 500-19 fitment for the 1931 Plymouth Export is available from Excelsior and Firestone. Those brand choices give the buyer more than one path within the same vintage size, while still keeping the tire in a bias-ply construction suited to the vehicle's period setup.
Brand alone should not be the only filter. It makes more sense to compare the specific tire series, the stated rim-width range, and whether the tire is aimed at general vintage use or a more specialized application. That approach keeps the selection grounded in fitment and intended use rather than name recognition alone.
How do I choose between the available 500-19 tires for a 1931 Plymouth Export?
Choosing between 500-19 tires comes down to matching the product to the car's purpose. The available options differ by tire series, brand, rim-width specification, weight, and product character, even though they share the same basic size, blackwall appearance, and bias-ply construction.
A Plymouth driven for general collector use may call for a different selection approach than one prepared for a more specialized setting. Comparing the actual wheel width on the car, reviewing any stated load figure, and thinking about how much originality in look matters will usually narrow the choice quickly.
Restoration & Appearance
Which tire should I choose for a period-style 1931 Plymouth Export?
A period-style 1931 Plymouth Export should begin with the correct 500-19 bias-ply size because the tire's overall look is closely tied to the car's early 1930s character. Staying with the original sizing format preserves the visual relationship between the tire, wheel, and body proportions.
From there, compare the available 500-19 products by series and intended use while keeping a traditional blackwall appearance in mind. Owners pursuing exact historical accuracy should still cross-check marque references or restoration records, since a correct size and construction do not automatically establish an exact original brand or tire pattern.
Does correct tire fitment matter for a 1931 Plymouth Export restoration?
Yes, correct tire fitment matters a great deal on a 1931 Plymouth Export. Early vehicles are visually sensitive to tire dimensions, so using the proper 500-19 size and a bias-ply construction helps maintain the car's expected stance, wheel-to-fender proportion, and authentic period presentation.
Proper fitment also affects more than appearance. The wrong wheel diameter or an unsuitable tire profile can create problems with clearance, steering feel, and overall presentation even before the car leaves the garage. A restoration-minded buyer should treat tire size, wheel size, and tire style as part of the vehicle's finished visual package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1931 Plymouth Export?
Yes. Modifications can affect tire fitment on a 1931 Plymouth Export even when the intended tire size remains 500-19. Changes to wheels, wheel width, suspension height, brake components, or body clearances can alter how a bias-ply tire sits and how much room it has during steering and road movement.
A car that has been restored over many decades may not still match its original wheel setup exactly. Checking the actual rim diameter, wheel width, and clearance at the front suspension and fenders is a smart step before mounting tires, especially on an early collector vehicle with parts sourced from different periods.
What should I inspect before driving a 1931 Plymouth Export on new tires?
Inspect the wheels, valve stems, mounting surfaces, and overall tire clearance before road use. It also makes sense to confirm proper inflation, look over steering and suspension condition, and make sure each tire shows no visible damage from shipping, handling, or installation before the car is driven.
An early Plymouth deserves a cautious first drive even with fresh tires installed. Recheck air pressure after the first outing, watch for rubbing during turns, and pay attention to any pull, vibration, or irregular contact pattern. Catching those issues early helps protect both the new tires and the car's vintage running gear.
How should 500-19 tires on a collector 1931 Plymouth Export be maintained?
Collector-car 500-19 tires should be kept properly inflated, inspected regularly for cuts, bulges, cracking, and irregular wear, and stored away from prolonged sunlight, heat, moisture, and ozone sources when the car is not in use. Low annual mileage does not eliminate the need for routine inspection.
Short, infrequent drives can be harder on a vintage car than regular use if tire condition is ignored between outings. Checking pressure before each drive, rolling the car periodically during long storage, and keeping an eye on how the tires age over time will help a 1931 Plymouth Export stay road-ready and presentable.
