The 1926 Studebaker Big 6 Cyl. came from an era when American cars were growing larger, more powerful, and more capable of sustained road travel, and tire choice was still closely tied to how a car was used and equipped. That matters here because this Studebaker appears with two bias-ply fitment paths: 32X6.75 and 700-20. Those sizes reflect very different vintage sizing conventions, and the available 700-20 selections add meaningful variation in brands, tire series, and sidewall presentation. For a restoration-minded owner, the key is confirming which wheel setup is actually on the car before choosing for appearance, road use, and proper rim compatibility.
Which Tire Size Is Right for The 1926 Studebaker Big 6 Cyl.
The 1926 Studebaker Big 6 Cyl. uses two primary tire sizes, and the first step is confirming which wheel and rim diameter the car actually has. Both fitments are bias-ply, but they differ sharply in sizing format and rim diameter, so the real decision starts with the wheel setup before moving on to sidewall style, tire series, or restoration-oriented appearance.
The 32X6.75 size uses an older diameter-by-section convention, where 32 refers to the tire's approximate overall diameter in inches and 6.75 refers to its section width. It is a bias-ply fitment and represents an early sizing system that looks quite different from later rim-diameter-first formats. On a 1926 Studebaker Big 6 Cyl., this size needs especially careful wheel confirmation because the tire dimensions point to a different wheel setup than the 700-20 option. This is the size to evaluate when the car retains an antique-style wheel arrangement rather than a later 20-inch fitment.
The 700-20 size is a numeric bias-ply format in which 7.00 represents the nominal section width in inches and 20 identifies the rim diameter. It is the more familiar of the two vintage fitments here and opens up a broader range of choices for a 1926 Studebaker Big 6 Cyl. Available options include Firestone, BFGoodrich, and Denman products, with Blackwall, Wide Whitewall, and Double-Whitewall presentations across series such as Firestone Balloon, Silvertown Classic Bias Ply, Highway Classic Truck, and Firestone Classic Truck. This size deserves close comparison if the car uses 20-inch wheels and the goal includes both proper vintage character and a specific sidewall look.
Fitment is straightforward at the sub-model level because the covered 1926 Studebaker Big 6 Cyl. Base is associated with the same two primary tire sizes. Checking the actual wheel setup still matters, since the decision is less about trim level and more about which wheel and tire format the car is wearing today.

Tire Size & Fitment
What tire size fits a 1926 Studebaker Big 6 Cyl.?
The 1926 Studebaker Big 6 Cyl. is associated with two primary bias-ply tire sizes: 32X6.75 and 700-20. Those are not simply two ways of writing the same tire size, because they use different vintage sizing conventions and correspond to different wheel setups.
The practical first step is confirming which wheels are actually on the car today. A restored or long-owned Studebaker may not still wear its earlier setup, and the rim diameter is especially important here because one fitment is tied to a 20-inch wheel while the other follows an antique diameter-by-section format.
What size rim does a 1926 Studebaker Big 6 Cyl. use?
The two tire fitments tied to the 1926 Studebaker Big 6 Cyl. point to two different rim diameters. The 32X6.75 size is associated with a 5.0-inch rim diameter, while 700-20 uses a 20-inch rim.
That difference makes wheel verification more important than usual before selecting tires. Reading the sidewall on the old tire can help, but it is also worth measuring the wheel and confirming what is physically on the car, especially if the Studebaker has gone through restoration work, wheel changes, or many decades of mixed service history.
What does 700-20 mean on a 1926 Studebaker Big 6 Cyl.?
On the 1926 Studebaker Big 6 Cyl., 700-20 is a numeric bias-ply size. The 7.00 identifies the tire's nominal section width in inches, and the 20 identifies the rim diameter in inches.
That size format is useful because it gives a clearer modern reference point for wheel diameter than some earlier systems do. Once the car is confirmed to use 20-inch wheels, the next step is comparing the available 700-20 tire styles by brand, sidewall treatment, tire series, and rim-width specification rather than assuming every vintage-looking option is the same.
Choosing the Right Tire
What should I consider when choosing a 700-20 tire for a 1926 Studebaker Big 6 Cyl.?
Start with the basics: confirm that the car actually uses the 700-20 fitment and that the wheel matches the tire's rim requirements. From there, the main differences are brand, tire series, sidewall presentation, intended vehicle character, and product specifications such as rim-width range and load capacity.
Some 700-20 options lean toward a more passenger-car presentation, including whitewall and double-whitewall styles, while others are more truck-oriented in look and specification. Matching the tire to the Studebaker's actual use matters just as much as matching the size, particularly if the car sees road driving rather than static display.
What sidewall styles are available for 1926 Studebaker Big 6 Cyl. tires?
Within the available 700-20 selections for the 1926 Studebaker Big 6 Cyl., sidewall styles include Blackwall, Wide Whitewall, and Double-Whitewall. Those choices can change the car's visual character substantially even when the size remains the same.
A blackwall generally gives a more restrained, utilitarian appearance, while whitewall treatments create a more formal and restoration-oriented presentation. Since sidewall style is an appearance choice rather than a fitment shortcut, the best approach is to confirm the wheel setup first and then choose the visual treatment that suits the Studebaker's intended look.
What brands offer tires for the 1926 Studebaker Big 6 Cyl.?
Available 700-20 tires for the 1926 Studebaker Big 6 Cyl. come from Firestone, BFGoodrich, and Denman. Those brands appear across several product types, including traditional passenger-style balloon and bias-ply offerings as well as truck-oriented selections.
Brand alone should not make the decision. It is more useful to compare the exact tire series, sidewall style, rim-width specification, and overall presentation that each option brings, especially when a pre-war vehicle may be restored for show, occasional touring, or a more utilitarian vintage-road purpose.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Studebaker Big 6 Cyl.?
A period-style choice for a 1926 Studebaker Big 6 Cyl. begins with using the correct primary size for the wheel setup actually on the car, then selecting a bias-ply tire that matches the vehicle's intended visual character. In 700-20, that can mean choosing among blackwall, wide whitewall, or double-whitewall presentations.
The right answer depends on whether the Studebaker is being finished as a formal restoration, a touring car, or a more utilitarian survivor. When exact historical accuracy matters, it helps to compare the tire choice against marque literature, period photos, and club guidance rather than relying on appearance alone.
How does tire construction affect the appearance of a restored 1926 Studebaker Big 6 Cyl.?
On a restored 1926 Studebaker Big 6 Cyl., bias-ply construction plays a major role in preserving the vehicle's traditional stance and visual proportions. That matters here because both primary fitments tied to this car are bias-ply sizes, not modern radial fitments.
Construction is only part of the appearance story, though. Sidewall treatment, tire series, and the wheel setup itself all shape how authentic or formal the finished car looks, so the final choice should balance visual goals with the way the Studebaker will actually be driven and presented.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Studebaker Big 6 Cyl.?
Yes. On a 1926 Studebaker Big 6 Cyl., wheel changes, brake conversions, suspension work, altered ride height, or later replacement rims can all affect which tire size is appropriate. That is especially important on this car because its two primary fitments point to very different wheel arrangements.
A Studebaker that has been restored over many decades may no longer match its earlier configuration exactly. Checking wheel diameter, wheel width, and available clearance at the fenders and steering components is a smart step before buying tires, even when the car appears outwardly stock.
What should I inspect before driving a 1926 Studebaker Big 6 Cyl. on new tires?
Before road use, inspect the wheels for condition, verify lug hardware, and make sure the tires are seated and inflated appropriately for their application. It is also worth checking the steering, suspension, and brake system on a 1926 Studebaker Big 6 Cyl., since an old chassis can influence how new tires behave.
A short, careful test drive is the best next step. Pay attention to clearance during turning, signs of rubbing, unusual vibration, and any tendency for the car to pull or wander, because those symptoms can point to wheel, alignment, or mechanical issues rather than a problem with the tire itself.
How should 700-20 tires on a collector 1926 Studebaker Big 6 Cyl. be maintained?
Collector-car 700-20 tires on a 1926 Studebaker Big 6 Cyl. should be checked regularly for pressure, tread condition, sidewall cracking, cuts, bulges, and slow air loss. Even a car that is driven infrequently needs routine inspection, because age and storage conditions can affect tire condition as much as mileage does.
Storage habits matter on a pre-war vehicle. Keeping the Studebaker away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and moving the car occasionally can reduce long static loading. A visual inspection before each outing is a sound routine for a vintage car that spends much of its time parked.
