1931 Duesenberg Tire Fitment Guide

1931 Duesenberg vehicles covered here use one tire size: 700-19. That size applies to the 1931 Duesenberg 8 Cyl. and mounts on a 19-inch rim. Available 700-19 products are bias-ply tires, and the listed rim width range for applicable products is 3.75 to 4.00 inches.

That makes the fitment side of a 1931 Duesenberg simpler than many multi-model year-and-make pages, because you are not choosing between several diameters or metric conversions. The important next step is to confirm the actual wheel on the car and then choose the 700-19 product that matches your goals for sidewall appearance, restoration accuracy, and intended driving style.

On a 1931 Duesenberg, 700-19 is a classic numeric bias-ply size. The 7.00 portion refers to the nominal section width in inches, while the 19 identifies the wheel diameter in inches. Unlike a modern metric radial size, it does not use a millimeter width, aspect ratio, and radial construction code.

That matters because a numeric pre-war tire should be read in the context of its era rather than translated too casually into a modern passenger-car size. If you are trying to keep a 1931 Duesenberg visually and dynamically correct, reading the code properly helps you stay with the intended 19-inch fitment and the tall, substantial bias-ply profile associated with the period.

The 1931 Duesenberg model covered here uses the same tire size throughout: 700-19 on the 8 Cyl. chassis. There is no split here between different model-specific sizes, so the year-and-make fitment remains centered on a single 19-inch tire specification.

That does not mean every 1931 Duesenberg should be restored the same way visually. Buyers still need to think about whether a blackwall or double-whitewall presentation best suits the body style, coachbuilder, and restoration direction of the individual car. Once the wheel diameter is confirmed, the decision shifts from size selection to appearance and authenticity priorities.

1931 Duesenberg tires in 700-19 are available with both Blackwall and Double-Whitewall sidewall styles. Firestone offerings appear in both treatments, while the listed Lester option is shown as a Blackwall. All of them remain within the correct pre-war bias-ply family for the size itself.

Sidewall style has a strong effect on how a Full Classic presents, especially on a large luxury chassis like a Duesenberg. Blackwalls often suit a more restrained or formal look, while a double-whitewall can emphasize the car’s presence and period glamour. The right choice comes down to the body style, restoration theme, and the standards you want the finished car to reflect.

Firestone and Lester both offer tires for 1931 Duesenberg fitment in 700-19. Firestone appears in multiple series, including Balloon and Classic Bias Ply variations, while Lester is represented with a classic bias-ply offering in the same size. All of the listed options stay within period-appropriate bias-ply construction.

For a buyer, that means brand choice is less about changing the basic fitment and more about selecting the product line and appearance that best suit the car. Looking at the available sidewall treatment, casing style, and any stated load information will usually tell you more than the brand name alone when you are narrowing down a 1931 Duesenberg tire.

For the 1931 Duesenberg in 700-19, Firestone Balloon and Firestone Classic Bias Ply share the same basic size and bias-ply construction, but they are presented as distinct series. The listed Firestone Balloon examples include blackwall and double-whitewall versions, carry a 1570-pound load figure at 36 psi, and show a 3.75 to 4.00-inch rim width range. The listed Firestone Classic Bias Ply example shows a 1,585-pound load figure at 36 psi.

That distinction gives restorers room to choose a tire that fits the visual and technical character they want without changing the actual 700-19 fitment. If one series better matches the sidewall look or product style you want on a 1931 Duesenberg, that is often the more useful deciding factor than a small difference in stated load figure within the same overall size category.

For 1931 Duesenberg 700-19 tires, the listed applicable rim width range is 3.75 to 4.00 inches on the products where rim width is specified. All of the tires mount on a 19-inch wheel diameter, which is the key dimensional constant across the fitment shown here.

That makes wheel verification straightforward but still important. Before choosing a tire for a 1931 Duesenberg, measure or confirm the actual wheel on the car rather than relying on assumptions from age alone. A correct 19-inch wheel still needs to fall within the appropriate width range for the specific tire you intend to run.

The listed 1931 Duesenberg 700-19 products do not carry TT or TL markings in the size line, so tube status should be confirmed against the specific tire and the wheel you plan to use. On a pre-war application like a 1931 Duesenberg, tube use is often part of the broader wheel-and-tire setup rather than something to assume from size alone.

That is especially important on original-style or older service wheels, where the wheel design may influence whether a tube is appropriate. When setting up a 1931 Duesenberg, confirm the actual sidewall marking and inspect the wheel condition at the same time. Treat the tube question as part of the complete wheel assembly, not as a separate afterthought.

For the 1931 Duesenberg fitment covered here, there is only one tire size: 700-19. That means there is no alternate tire diameter within this page’s fitment to compare against the original wheels. The central compatibility point is that the tire mounts on a 19-inch rim.

If your 1931 Duesenberg still wears its original-style wheels, the practical job is to confirm their condition, exact diameter, and width before final selection. Original wheels can age just as much as tires do, and a large, heavy pre-war car places real demands on the wheel assembly. Verifying that foundation first is the best way to avoid fitment surprises later.

A 1931 Duesenberg should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate sidewall cracking. Because the car uses bias-ply tires, long stationary periods can also encourage flat-spotting more readily than a radial tire would on a later vehicle.

If the car will sit for extended periods, keep the tires properly inflated, move the car periodically, or use stands when appropriate for long-term storage. A heavy luxury car places a substantial static load on its tires, so small storage habits make a real difference. Clean, stable conditions and occasional movement help preserve both appearance and road manners.

Tires on a 1931 Duesenberg should be evaluated by age as much as by tread depth. On a collector car, five to seven years is a sensible inspection window for closer age-related review, and around ten years is a common point for serious replacement consideration even if the car has seen limited mileage. The DOT date code is a useful reference on later reproduction tires.

That approach matters because many pre-war cars travel only occasional miles, which can make old tires look healthier than they really are. Rubber hardens, sidewalls age, and internal structure changes over time whether or not the odometer climbs quickly. A 1931 Duesenberg deserves the same age-based caution as any other valuable collector automobile.

Tires on a 1931 Duesenberg should be inspected before every drive and again before any longer outing or event. Look closely for sidewall cracking, cuts, bulges, irregular tread wear, and signs that the tire has not been holding pressure consistently. If your setup uses tubes, the condition of the valve stem area deserves attention as well.

Pre-drive inspection is especially worthwhile on a seldom-driven car because problems often develop quietly during storage rather than on the road. A quick walkaround can catch age-related issues before they become expensive or dangerous. On a large pre-war chassis, finding a problem in the garage is far better than discovering it once the car is underway.

A 1931 Duesenberg 8 Cyl. would have been fitted in period with bias-ply tires rather than modern radial construction. The available 700-19 offerings align with that era-correct construction type and preserve the tall pre-war profile expected on a grand American luxury chassis of the early 1930s. Original-equipment brand selection could vary by market, body delivery, and owner preference, so construction type and size are the first authenticity markers to get right.

For a serious restoration, start with the correct 700-19 size and then refine the choice by sidewall style and overall presentation. If the car is headed for judged events, it is wise to compare your selection with period photos, marque references, and Duesenberg club guidance. Those sources can help confirm what is most convincing for your particular coachbuilt car.

Correct tire fitment matters a great deal when showing a 1931 Duesenberg because judges and knowledgeable enthusiasts notice size, construction type, and sidewall presentation quickly. A proper 700-19 bias-ply tire keeps the car within the visual language of the early 1930s, while an obviously modern construction or an out-of-character sidewall treatment can distract from an otherwise strong restoration.

That does not mean every event applies the same standard, but authenticity expectations are usually higher on a prominent Full Classic than on an ordinary driver. If the car is being prepared for concours-level display, confirm the event’s judging guidance and compare your tire choice with period-correct examples. Tire fitment is one of the easiest details to get visibly right.

For the 1931 Duesenberg in 700-19, the available sidewall presentations include blackwall and double-whitewall. Both remain within the same size family and bias-ply construction, so the difference is visual rather than dimensional. The blackwall reads more restrained, while the double-whitewall creates a brighter, more formal period statement on a large pre-war chassis.

Choosing between them depends on how the individual 1931 Duesenberg is being interpreted. A conservative touring body may look more natural on blackwalls, while a more flamboyant coachbuilt car can carry double-whitewalls convincingly. Review period photos of similar bodies and consult marque specialists if you want the sidewall treatment to align closely with historical presentation.

A properly maintained 1931 Duesenberg tire in the correct 700-19 bias-ply size can be used for normal road driving when the tire is in sound condition and suited to the wheel. The listed products here are traditional bias-ply designs rather than modern high-speed radials, and no separate speed-rating letters are shown in the size markings provided for these options.

On a car from 1931, tire capability is only one part of the road-use picture. Brakes, steering, suspension, wheel condition, and the car’s overall mechanical state often matter just as much as the tire itself at real-world speeds. Highway use should be approached with the expectations appropriate to a large pre-war automobile, not a modern touring car.

For 1931 Duesenberg 700-19 tires, listed load figures include 1,570 pounds at 36 psi and 1,585 pounds at 36 psi on specific products. Those figures describe the tire’s rated load relationship at that pressure, not automatically the exact operating pressure every individual car should use in service. Inflation should always be considered in the context of the vehicle, wheel, and the specific tire selected.

The best practice is to compare the original vehicle guidance with the tire manufacturer’s recommendations for the reproduction tire you plan to run. A 1931 Duesenberg is not a car to inflate by guesswork or by copying another size’s pressure. Use the tire’s own published rating as a boundary and tune within appropriate guidance for the actual vehicle setup.

Before a longer drive in a 1931 Duesenberg, inspect each tire for cracking, cuts, bulges, uneven wear, and pressure loss, and examine the valve stems and spare as part of the same check. Confirm that the 700-19 tires are seated properly on the 19-inch wheels and that the wheel hardware and overall wheel condition inspire confidence.

That tire inspection should happen alongside a broader pre-drive review of fluids, brakes, steering, cooling, and electrical systems, because a 1931 Duesenberg’s age makes every system part of the trip equation. A longer outing is much easier to enjoy when the car has been checked methodically in advance. Preparation is part of responsible operation for any significant pre-war automobile.
