The 1930 Studebaker Commander comes from an era when American cars were rapidly gaining refinement, presence, and long-distance capability, and Studebaker had built a strong reputation for solid engineering and distinctive styling. For owners of this exact model, tire selection centers on two period bias-ply sizes, 29X5.50 and 550-19, both tied to 19-inch fitment. That makes the real decision less about modern-size guessing and more about choosing the right period-style presentation, especially since 550-19 is available in both blackwall and wide whitewall form. For restoration work or road use, wheel condition, actual wheel size, and the appearance you want to preserve all matter before making a choice.
Which Tire Size Is Right for The 1930 Studebaker Commander
The 1930 Studebaker Commander uses two primary tire sizes, and both covered sub-models share them. Both are bias-ply fitments associated with 19-inch use, so the key is confirming which sizing convention matches the wheels and tire setup on the car. Once that is settled, the decision shifts to period-style appearance and product details rather than moving between unrelated modern fitments.
29X5.50 is an antique diameter-by-section size, meaning the first number refers to an approximate overall tire diameter of 29 inches and the second number refers to an approximate section width of 5.50 inches. It is a bias-ply fitment suited to the pre-war sizing conventions used on cars like the 1930 Studebaker Commander. This format is especially relevant to owners trying to stay close to an early tire-marking system rather than using a later numeric size designation. It is a useful size to evaluate when authenticity of presentation and compatibility with the car's existing wheel setup are the main priorities.
550-19 is a numeric bias-ply size in which 550 represents an approximate 5.50-inch nominal section width and 19 identifies the rim diameter. On a 1930 Studebaker Commander, it reflects a familiar vintage replacement format for 19-inch applications and is the size with available product choices. BFGoodrich offers this size in the Silvertown Classic Bias Ply series with both blackwall and wide whitewall sidewall treatments. It is the practical size to focus on when you want a defined 19-inch bias-ply option and the ability to choose a more understated or more restoration-oriented look.
Tire fitment is straightforward across the covered 1930 Studebaker Commander sub-models because both the 6 Cyl. and 8 Cyl. use the same two bias-ply sizes. Checking the sub-model still helps confirm that the car has not been altered and that the wheel and tire setup still matches the intended 19-inch application.

1930 Studebaker Commander 6 Cyl.
The 1930 Studebaker Commander 6 Cyl. uses the same pair of bias-ply tire sizes found across this model range, so fitment does not split into a separate size path here. That keeps tire selection focused on the wheel setup already on the car and on whether a blackwall or wide whitewall presentation better suits the vehicle's intended finish.
The 1930 Studebaker Commander 8 Cyl. follows the same tire-size pattern as the 6-cylinder version, with both primary bias-ply sizes applying here as well. For most owners, the important step is confirming the existing 19-inch wheel arrangement and then choosing the sidewall treatment and period-style tire presentation that best matches the car.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1930 Studebaker Commander Tires for Sale
Available 550-19 options center on BFGoodrich's Silvertown Classic Bias Ply series, with a choice between blackwall and 3.25-inch wide whitewall styling. The shared 19-inch fitment and matching load specification make appearance and wheel-width compatibility the main points to compare in the product grid.
These 1930 Studebaker Commander tire FAQs focus on shared 6-cylinder and 8-cylinder fitment, the difference between 29X5.50 and 550-19 sizing, sidewall appearance choices, and the wheel, condition, and maintenance checks that matter before road use.
Tire Size & Fitment
What tire size fits a 1930 Studebaker Commander?
The 1930 Studebaker Commander uses two primary bias-ply tire sizes: 29X5.50 and 550-19. Both the 6 Cyl. and 8 Cyl. versions use these same sizes, so the fitment question is less about engine designation and more about which size marking matches the car's present wheel and tire setup.
That distinction matters because 29X5.50 and 550-19 represent different vintage sizing formats even though they relate to the same general period of fitment. Start by confirming the wheel diameter on the car, then compare the existing tire markings and wheel dimensions before selecting a replacement.
What size rim does a 1930 Studebaker Commander use?
The 1930 Studebaker Commander uses a 19-inch rim with its primary tire fitment. The 550-19 size states that rim diameter directly, and available products in that size are built for 19-inch application with rim-width compatibility in the narrow vintage range used on early vehicles.
Rim diameter should be confirmed on the actual wheels before ordering tires, especially on a car that may have changed hands several times over many decades. A replacement tire should match both the wheel diameter and the wheel width already on the vehicle, not just the badge on the hubcap.
Do all 1930 Studebaker Commander sub-models use the same tire size?
Yes. The covered 1930 Studebaker Commander sub-models, including the 6 Cyl. and 8 Cyl., share the same two primary bias-ply tire sizes: 29X5.50 and 550-19. There is no separate tire-size split between those two versions within this fitment group.
That makes sub-model identification less critical than it would be on a vehicle with trim-specific wheel packages, but it is still wise to inspect what is on the car now. A Studebaker restored years ago or updated with replacement wheels may no longer reflect the original style of 19-inch setup.
Choosing the Right Tire
What should I consider when choosing a 550-19 tire for a 1930 Studebaker Commander?
Start with the basics: confirm that the car is using the 550-19 size and that the wheels remain 19-inch rims within the appropriate width range. From there, the main choices are construction style, which remains bias-ply here, and sidewall appearance, since 550-19 is available in both blackwall and wide whitewall form.
That means the right selection often comes down to how the Studebaker will be used and presented. A more understated blackwall can suit a simpler touring look, while a wide whitewall creates a stronger restoration-oriented visual statement without changing the tire's vintage sizing format.
What sidewall styles are available for 1930 Studebaker Commander tires?
For the 1930 Studebaker Commander, available 550-19 products include both Blackwall and Wide Whitewall sidewall styles. Both are BFGoodrich Silvertown Classic Bias Ply tires, so the visual difference is the main distinction rather than a change to the underlying vintage size or basic construction type.
Choosing between them depends on the look you want the car to carry. A blackwall keeps the presentation restrained and functional, while a 3.25-inch wide whitewall gives the car a brighter, more formal pre-war appearance that many restoration-minded owners prefer on display vehicles.
What brands offer tires for the 1930 Studebaker Commander?
Available products for the 1930 Studebaker Commander in 550-19 come from BFGoodrich. Those choices appear within the Silvertown Classic Bias Ply series and include both blackwall and wide whitewall versions, giving owners an appearance decision within the correct vintage numeric bias-ply size.
Since the available brand choice is focused rather than broad, selection becomes more about matching the tire's look and wheel compatibility to the car. Compare the sidewall treatment, confirm the rim width, and make sure the overall presentation suits the level of restoration or regular driving planned.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Studebaker Commander?
A period-style 1930 Studebaker Commander should stay with one of its primary bias-ply fitments, either 29X5.50 or 550-19, depending on the wheel and tire setup already on the car. For owners choosing among available products, 550-19 provides a practical path with vintage bias-ply construction and traditional sidewall options.
Appearance then becomes the deciding factor. A blackwall delivers a simpler, more restrained look, while a wide whitewall creates a more formal restoration-style presentation. If exact historical accuracy matters at a show level, compare the tire choice against marque references and period photography for the specific car.
Does correct tire fitment matter for a 1930 Studebaker Commander restoration?
Yes, tire fitment plays a major role in how a 1930 Studebaker Commander looks and sits, and it also affects whether the car remains visually consistent with its era. Using the correct vintage size format and a proper 19-inch bias-ply setup helps preserve the tall, narrow stance expected of an early-1930s automobile.
Fitment matters beyond appearance as well. The wrong wheel diameter, an unsuitable rim width, or an oversized substitute can change the car's proportions and create clearance concerns. On a restoration, tire selection should support both the visual character of the car and the actual wheel hardware on it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Studebaker Commander?
Yes. A 1930 Studebaker Commander may have replacement wheels, altered suspension components, or bodywork changes from earlier restoration work, and any of those can affect tire fitment. Even when the intended size is 29X5.50 or 550-19, the actual clearance and wheel compatibility can change if the car no longer matches its traditional setup.
Inspect the wheels closely before choosing tires. Confirm the wheel diameter, measure the rim width, and look for steering or fender clearance issues that might appear at full lock or over suspension movement. Older collector cars often carry decades of changes that are not obvious at first glance.
What should I inspect before driving a 1930 Studebaker Commander on new tires?
Before road use, inspect the wheels for rust, cracks, bent flanges, and general structural condition, then verify that the tires are seated properly and inflated correctly for their application. It is also wise to check the valve stems, wheel fasteners, and any signs of interference at the fenders, brakes, or steering components.
A short, careful test drive should follow any tire change on a pre-war vehicle. Pay attention to tracking, vibration, air retention, and visible clearance under turning and braking. On a car that has been stored for long periods, the rest of the chassis deserves the same level of inspection.
How should 550-19 tires on a collector 1930 Studebaker Commander be maintained?
550-19 tires on a collector 1930 Studebaker Commander should be kept clean, properly inflated, and inspected regularly for cracking, cuts, bulges, uneven wear, and gradual air loss. Because collector cars often spend long periods parked, tire age and storage conditions can matter just as much as visible tread depth.
Good storage practice helps preserve both appearance and service life. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or generators. Regular pressure checks and periodic inspection before each drive are especially important on low-use vintage vehicles.
