1926 Duesenberg 8 Cyl. Tires

The 1926 Duesenberg 8 Cyl. is associated with two primary tire sizes: 31X6.75 and 700-19. Both are bias-ply sizes, but they use different sizing systems, and they do not point to the same rim diameter. That means the tire decision starts with identifying which wheel-and-tire combination is actually on the car.

A pre-war car may have been restored, re-wheeled, or changed over decades of ownership, so the safest next step is to inspect the existing wheel and tire carefully. Confirm the rim diameter, compare the size stamped on the current tire if readable, and make sure the replacement matches the car's actual setup rather than assuming every 1926 Duesenberg 8 Cyl. is configured the same way.

The two tire sizes tied to the 1926 Duesenberg 8 Cyl. use different rim diameters. The 31X6.75 size is associated with a 5.0-inch rim diameter, while 700-19 uses a 19-inch rim diameter. Since those are entirely different wheel dimensions, the car's actual wheel setup has to be confirmed before selecting a replacement tire.

This matters because antique sizing can be easy to misread if a buyer is more familiar with later numeric or metric sizes. Measuring the wheel and checking the current tire marking will usually resolve the question quickly. On an older collector car, it is also wise to confirm that all four wheels match and that no previous owner mixed wheel types during an earlier restoration or service interval.

700-19 is a numeric bias-ply tire size. The 700 portion represents an approximate 7.00-inch nominal section width, while the 19 identifies a 19-inch rim diameter. On the 1926 Duesenberg 8 Cyl., it is one of the primary fitments and the size with the broadest visible product choice in traditional bias-ply styles.

Understanding that format helps avoid confusion with antique diameter-by-section sizing such as 31X6.75, which reads very differently. For a buyer choosing 700-19, the next practical step is comparing sidewall style, tire series, and rim-width compatibility where stated. That approach keeps the selection grounded in the actual wheel on the car instead of relying on the size code alone.

Start with the correct size and construction: 700-19 in bias-ply form. From there, the meaningful differences are visual presentation, tire series, and wheel compatibility details. Firestone and Lester both appear in this size, and Firestone Balloon as well as classic bias-ply series are part of the available mix.

The right choice depends on how the car is used and how traditional you want it to look. A blackwall presents differently than a wide whitewall or double-whitewall, even when the size is the same. Rim-width specifications are also worth checking where stated, especially on a restoration that may not still wear its original wheels after many decades of service and ownership changes.

For the 700-19 fitment on a 1926 Duesenberg 8 Cyl., available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those choices allow the same basic size to take on a more restrained touring look or a more formal period presentation, depending on the direction of the restoration and the owner's visual preference.

Sidewall style changes appearance far more than many buyers expect, especially on a large pre-war automobile with tall, prominent tires. The best approach is to choose a treatment that suits the car's overall finish and trim level without assuming any one sidewall is automatically correct for every example. Buyers focused on historical precision should compare their choice against photos, marque references, or restoration records for their own car.

The 700-19 size for the 1926 Duesenberg 8 Cyl. is available from Firestone and Lester. Within those brand choices, the visible product mix includes Firestone Balloon and classic bias-ply offerings, giving the buyer a combination of brand selection and styling variation rather than just one uniform tire in the correct size.

Brand choice should be considered alongside the tire's sidewall presentation, series character, and any wheel-spec detail that applies to the product. For a collector car of this age, the most useful question is not simply which brand name appears on the sidewall, but which tire best matches the car's wheels, intended road use, and restoration presentation once the fitment itself has been confirmed.

A period-style starting point for a 1926 Duesenberg 8 Cyl. is the correct bias-ply size for the wheel actually fitted to the car, either 31X6.75 or 700-19. For cars using 700-19, Firestone and Lester options keep the construction and overall presentation in line with what buyers usually expect from a pre-war luxury automobile.

The finer decision often comes down to sidewall treatment and the overall look of the restoration rather than size alone. A blackwall gives one character, while wide whitewall and double-whitewall versions create a more formal visual statement. If historical exactness matters beyond a broadly period-style result, the smartest next step is checking marque-specific references, old photographs, or restoration records tied to the individual car.

On a restored 1926 Duesenberg 8 Cyl., bias-ply construction has a major influence on appearance because it preserves the tall, early-style tire profile associated with the era. Since the primary fitments here are bias-ply, the construction itself supports an authentic pre-war visual impression in a way that matches the car's age and proportions.

Appearance is not only about size; it is also shaped by sidewall treatment and the tire's overall character once mounted on the wheel. Even within 700-19, blackwall, wide whitewall, and double-whitewall choices can change the car's visual emphasis. For restoration-minded buyers, construction and sidewall should be considered together so the finished stance looks coherent from wheel to fender line.

Yes. On a 1926 Duesenberg 8 Cyl., later wheel changes, brake updates, suspension work, or long-ago restoration choices can affect which tire size actually belongs on the car today. That is especially important here because 31X6.75 and 700-19 do not share the same rim diameter, so a visual assumption is not enough.

Any collector car that has been apart over the years deserves a careful wheel and clearance check before new tires are installed. Measure the wheel, inspect the current tire markings, and confirm that all four corners match. Steering clearance and fender space should also be reviewed, particularly if the car has non-original wheels or chassis changes that altered its original tire-and-wheel relationship.

Before road use, inspect the wheels, valve hardware, and the overall condition of the mounting surfaces as carefully as the new tires themselves. A 1926 Duesenberg 8 Cyl. places a lot of visual and functional importance on its wheel-and-tire assembly, so proper installation, correct inflation, and an even seated tire should all be confirmed before the car moves under load.

It also helps to check steering movement at low speed, verify that the tires clear fenders and suspension components, and make sure the brakes and wheel bearings are in suitable condition for road use. On a low-mile collector car, tire age is only one part of the picture. The surrounding chassis systems deserve equal attention before any meaningful drive, especially after long storage.

Tires on a collector 1926 Duesenberg 8 Cyl. should be inspected regularly for pressure loss, tread wear, sidewall cracking, cuts, and any sign of distortion from long stationary periods. Bias-ply tires on pre-war cars often spend more time stored than driven, so condition checks matter even when mileage remains very low.

Storage environment also makes a difference. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tire casing over time. Rolling the car periodically can reduce flat spotting during long rests, and any persistent vibration, pull, or air loss should be investigated promptly so a small issue does not become a larger wheel, tire, or chassis problem.
