1931 Stutz MB Tires

The 1931 Stutz MB uses a 700-20 tire size. This is a bias-ply fitment, and the covered 8 Cyl. sub-model uses that same 700-20 size rather than a different primary option.

That means the main decision is not choosing between multiple factory-type sizes, but choosing the right 700-20 tire for the car’s wheels and intended appearance. A Stutz that retains restoration-oriented wheels may call for a different rim-width match and sidewall treatment than a car set up for more utilitarian road use, so the wheel dimensions should be confirmed before selecting among the available products.

The 1931 Stutz MB uses a 20-inch rim with its 700-20 tire size. That 20-inch diameter is the critical wheel dimension because the tire must match the rim diameter exactly.

Wheel width matters too, especially since 700-20 products in this application are offered for different rim-width ranges. A Firestone Balloon tire and a BFGoodrich Silvertown Classic Bias Ply tire do not share the same width requirements, so it is smart to verify the actual wheel dimensions on the car before choosing a tire based only on the size stamped on the sidewall.

Yes. The 1931 Stutz MB 8 Cyl. uses the same 700-20 bias-ply tire size as the covered MB fitment. There is no separate primary tire size shown for that sub-model.

Even with shared size, the best product choice can still vary depending on the car’s wheel width and the look you want. Some owners may prefer a blackwall for a simpler or more service-oriented presentation, while others may lean toward wide whitewall or double-whitewall styling to suit a more formal pre-war restoration approach.

Start with the correct 700-20 size and confirm that the tire’s bias-ply construction matches the type of fitment you want to keep on the car. Then compare rim-width compatibility, sidewall style, tire series, and whether the tire is aimed more at passenger-car presentation or truck-type service.

A Firestone Balloon tire, a BFGoodrich Silvertown Classic Bias Ply, and a truck-oriented 700-20 may all share the same nominal size while serving different goals. The right choice depends on whether the Stutz is being finished with a restoration-minded look, prepared for occasional touring, or fitted with wheels that favor one rim-width range over another.

The 1931 Stutz MB’s 700-20 tire choices include blackwall, wide whitewall, and double-whitewall sidewall styles. Those options give the car a noticeably different visual character even when the tire size itself stays the same.

Sidewall selection should follow the personality of the car and the type of restoration or preservation being pursued. A blackwall usually delivers a simpler, more understated presentation, while wide whitewall and double-whitewall tires create a more formal pre-war appearance. The visual choice should still be balanced against wheel-width compatibility and the specific tire series being considered.

700-20 tires for the 1931 Stutz MB are available from Firestone, BFGoodrich, and Denman. The available series include Firestone Balloon, Silvertown Classic Bias Ply, Highway Classic Truck, and Firestone Classic Truck.

Brand alone should not decide the purchase. It is more useful to compare how each tire is configured, including sidewall treatment, rim-width range, load specification where stated, and whether the tire has a passenger-car or truck-oriented character. That approach helps narrow the field to the tires that make the most sense for the way the Stutz is equipped and used.

A period-style 1931 Stutz MB should begin with the correct 700-20 bias-ply size and then narrow the choice by sidewall treatment and tire series. Firestone Balloon and BFGoodrich Silvertown Classic Bias Ply options fit naturally into that traditional pre-war visual range.

Appearance details matter on a car like this, but exact originality should be judged against marque references, period photos, or restoration documentation for the individual car. A wide whitewall or double-whitewall may suit one presentation, while a blackwall may better support another, so the right answer depends on the look being recreated rather than size alone.

The 1931 Stutz MB’s primary fitment is a 700-20 bias-ply tire, and that construction plays a major role in preserving the car’s pre-war look. Bias-ply proportions and sidewall presentation help maintain the tall, formal stance expected on a luxury car from this period.

Even within bias-ply construction, sidewall style changes the result significantly. A blackwall gives a more restrained appearance, while wide whitewall and double-whitewall versions create a more decorative and upscale presentation. For a restoration-focused car, construction and sidewall treatment should be chosen together so the tire supports both fitment needs and the overall visual theme.

Yes. Even though the primary size is 700-20, modifications can affect how that tire works on a 1931 Stutz MB. Changes to wheel width, wheel design, suspension height, brake components, or fender clearance can all influence whether a specific 700-20 product is suitable.

That is especially important here because available 700-20 tires do not all share the same rim-width requirements. A car with replacement wheels or later hardware should have the actual wheel dimensions checked before purchase. Clearance around the front suspension, steering travel, and bodywork also deserves attention on a large pre-war chassis before any road miles are added.

Before driving a 1931 Stutz MB on new tires, inspect the wheels for correct diameter and width, check that the beads seat properly, and confirm that the tires clear fenders and steering components through their full range of motion. Lug hardware, valve stems, and inflation should also be checked carefully.

A pre-war car benefits from a broader road-readiness inspection at the same time. Steering play, brake condition, wheel-bearing health, and suspension wear can all affect how the car feels on fresh tires. It is also wise to recheck pressure and fastener tightness after the first short drive, especially if the car has been inactive for long periods.

700-20 tires on a collector 1931 Stutz MB should be kept at appropriate pressure for the specific tire in use, inspected regularly for cracking, cuts, bulges, and air loss, and protected from long exposure to sunlight, moisture, and ozone-producing equipment. Low annual mileage does not eliminate the need for inspection.

Collector cars often spend more time parked than driven, so storage habits matter. Moving the car occasionally can help avoid prolonged flat spotting, and clean, dry storage is preferable to damp or heat-soaked spaces. Tires should also be checked before each outing, since age-related condition changes are easy to miss on a vehicle that sees only occasional use.
