1928 Studebaker Commander Tires

The 1928 Studebaker Commander uses two primary bias-ply tire sizes: 29X5.50 and 550-20. Both sizes belong to the same covered vehicle fitment and reflect period sizing conventions rather than modern metric or P-metric designations.

The most important next step is confirming which size is actually mounted on the car or which wheel setup the car currently retains. A late-1920s vehicle may have had wheels, tires, or markings changed over time, so replacement should start with the exact size on the wheel, the wheel diameter, and the visual style you want to maintain.

The 1928 Studebaker Commander uses a 20-inch rim with its covered tire fitments. The numeric 550-20 size states that rim diameter directly, and the available products in that size are built for 20-inch wheels.

Wheel diameter should be confirmed on the car before ordering tires, especially on an older collector vehicle that may have seen replacement wheels at some point in its life. Wheel width also matters on antique applications, so the rim itself should be checked carefully along with any tube-type requirements and the overall condition of the wheel before the car returns to service.

Yes. The covered 1928 Studebaker Commander 6 Cyl. uses the same two primary tire sizes, 29X5.50 and 550-20, and both are bias-ply fitments. That keeps sub-model fitment relatively simple compared with later vehicles that split sizes by trim or package.

The real distinction is usually not the sub-model name but the size convention already on the car and the condition of the wheels underneath it. Many owners will want to match the existing period-style setup, while others may focus more on sidewall presentation, such as blackwall versus wide whitewall, within the correct 550-20 fitment.

Start with the basics: correct size, bias-ply construction, and proper 20-inch wheel compatibility. For the 1928 Studebaker Commander, 550-20 is also available in more than one visual style, so appearance becomes part of the decision along with the mechanical fitment.

A BFGoodrich Silvertown Classic Bias Ply in blackwall gives a more restrained presentation, while the 3.25-inch wide whitewall creates a stronger restoration-oriented look. It also helps to compare rim-width suitability, load capacity, and whether the car will be used mainly for show, local touring, or occasional longer drives on secondary roads.

For the 1928 Studebaker Commander's available 550-20 products, the sidewall styles include blackwall and wide whitewall. The wide whitewall offering is a 3.25-inch whitewall, while the other option keeps a plain black sidewall presentation.

That choice affects the car's finished look more than its basic fitment, so the better option depends on your restoration goals and how much visual emphasis you want from the tires. Owners aiming for a more formal late-1920s appearance often pay close attention to whitewall width, while others prefer the simpler and less decorative look of a blackwall tire.

The available 550-20 products for the 1928 Studebaker Commander are offered in the BFGoodrich Silvertown Classic Bias Ply series. That keeps the selection focused within a traditional bias-ply line rather than spreading across multiple modern construction families.

Since the series remains consistent, the main comparison points shift to sidewall style, weight, rim-width fitment, and the type of appearance you want on the completed car. That can simplify the buying process for owners who already know they want to stay with a period-style bias-ply tire rather than compare several different performance-oriented product categories.

A period-style 1928 Studebaker Commander should stay with one of its proper bias-ply fitments, either 29X5.50 or 550-20, depending on the wheel and size convention already on the car. Within the currently available 550-20 options, a BFGoodrich Silvertown Classic Bias Ply keeps the tire in the right visual and construction family for the era.

The appearance decision then becomes more specific: blackwall for a simpler look or 3.25-inch wide whitewall for a more decorative late-1920s presentation. When exact originality matters, it is worth comparing your car against marque references, period photos, and restoration documentation so the sidewall treatment matches the character you want to preserve.

Tire construction has a major visual effect on a restored 1928 Studebaker Commander because the car belongs to an era defined by tall, narrow bias-ply proportions and traditional sidewall treatments. Keeping the car on its correct bias-ply size family helps preserve the stance and presentation expected from a late-1920s automobile.

Appearance is influenced not only by the size code but also by sidewall style, especially when choosing between blackwall and wide whitewall. Even small visual changes can alter how authentic the finished car feels, so construction, profile, and sidewall details should all be considered together rather than treated as separate cosmetic decisions.

Yes. Tire fitment on a 1928 Studebaker Commander can be affected if the car has replacement wheels, altered ride height, brake updates, or body and fender changes made during an older restoration. On antique vehicles, even a seemingly minor wheel change can alter the correct relationship between tire size and rim.

A careful inspection should include wheel diameter, wheel width, tire-to-fender clearance, and steering clearance at full lock. Antique cars also deserve close attention to wheel condition itself, since age, corrosion, and prior repairs can matter as much as the tire choice when preparing the vehicle for reliable road use.

Before driving a 1928 Studebaker Commander on new tires, inspect the wheels, valve hardware, and overall tire seating, then check inflation pressure, sidewall condition, and clearance around fenders and steering components. On an antique car, the wheel and tire relationship deserves special attention before the first road miles.

A short, cautious initial drive is a smart way to confirm there is no rubbing, unusual vibration, or air loss. It also helps to recheck pressure after the tires have settled, and to look over suspension and steering wear points, since older mechanical components can influence how confidently a newly tired collector car behaves on the road.

550-20 tires on a collector 1928 Studebaker Commander should be maintained with regular pressure checks, visual inspections for cracking, cuts, bulges, and uneven wear, and careful storage away from prolonged sunlight, moisture, and ozone sources. Collector cars often age their tires by time and environment as much as by mileage.

Routine inspection matters even when the car is driven only occasionally, because long periods of sitting can hide air loss or sidewall aging. It is also wise to keep the wheels clean, monitor how the tires are supporting the car at rest, and inspect the spare if one is carried as part of the car's touring setup.
