The 1929 Studebaker Commander came from an important period when American automakers were balancing refinement, style, and growing highway capability. Whether equipped as a six-cylinder or eight-cylinder Commander, this is a late-1920s car whose tire choice has a major effect on both stance and authenticity of presentation. For this model, the primary fitments are 29X5.50 and 550-19, both bias-ply sizes built around a 19-inch wheel. That leaves the real decision centered on understanding the two size formats and choosing between blackwall and wide whitewall presentation. For restoration-minded owners, wheel dimensions, overall appearance, and careful pre-road inspection all matter before putting the car back into regular use.
Which Tire Size Is Right for The 1929 Studebaker Commander
The 1929 Studebaker Commander uses two primary tire sizes, and both are bias-ply fitments tied to the same 19-inch rim diameter. Since the 6 Cyl. and 8 Cyl. sub-models share both size options, the main task is understanding the two sizing systems and confirming which tire presentation and wheel dimensions make the most sense for the car in front of you.
A 29X5.50 tire uses an older diameter-by-section format, where 29 refers to the approximate overall tire diameter and 5.50 refers to the nominal section width in inches. It is a bias-ply fitment suited to the late-1920s character of the 1929 Studebaker Commander and reflects the way many cars of the period were originally sized. This format is especially useful for owners focused on traditional fitment language and period-style proportions. It should still be matched carefully to the actual wheel and vehicle setup, particularly if the car has been restored with replacement wheels or altered running gear.
A 550-19 tire uses vintage numeric bias-ply sizing, with 5.50 representing the nominal section width in inches and 19 representing the wheel diameter. On the 1929 Studebaker Commander, this size offers a straightforward path for buyers who want a current bias-ply option built for a 19-inch rim. Available choices include BFGoodrich Silvertown Classic Bias Ply tires in both blackwall and 3.25-inch wide whitewall form. This size is a strong place to start when the goal is a usable restoration-oriented tire with a clear sidewall-style choice.
Tire fitment is straightforward across the covered 1929 Studebaker Commander sub-models, since both the 6 Cyl. and 8 Cyl. share the same two bias-ply size options. Checking the exact sub-model still helps confirm that the car has remained on the expected wheel setup over time.

1929 Studebaker Commander 6 Cyl.
The 1929 Studebaker Commander 6 Cyl. uses the same pair of primary bias-ply size options found across the covered Commander range. That makes the selection process more about choosing the preferred vintage size format and sidewall appearance than sorting through different sub-model-only fitments.
The 1929 Studebaker Commander 8 Cyl. also shares the same primary bias-ply fitment pattern as the 6 Cyl. version. Tire selection can therefore stay focused on period-style presentation, wheel confirmation, and whether blackwall or wide whitewall better suits the car's restoration direction.
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 1929 Studebaker Commander Tires for Sale
Available 550-19 choices center on BFGoodrich Silvertown Classic Bias Ply tires, with blackwall and wide whitewall sidewall treatments. These options share 19-inch rim fitment and similar vintage bias-ply character, while giving restoration-minded owners a clear appearance decision.
These 1929 Studebaker Commander tire FAQs focus on the two primary sizes, 19-inch wheel fitment, bias-ply construction, sidewall appearance choices, and the checks that matter before a restored or collector car returns to regular road use.
Tire Size & Fitment
What tire size fits a 1929 Studebaker Commander?
The 1929 Studebaker Commander uses two primary tire sizes: 29X5.50 and 550-19. Both are bias-ply fitments, and both the 6 Cyl. and 8 Cyl. Commander sub-models use these same size options.
The key difference is the sizing language rather than a major split between sub-models. 29X5.50 is an older diameter-by-section format, while 550-19 is a numeric bias-ply size tied clearly to a 19-inch rim, so the next step is confirming the wheel setup on the car and choosing the presentation that best suits its restoration goals.
What size rim does a 1929 Studebaker Commander use?
The 1929 Studebaker Commander uses a 19-inch rim with its primary tire fitments. That 19-inch diameter aligns with the 550-19 tire size and is the wheel diameter to confirm before selecting replacement tires.
Wheel diameter is only part of the fitment picture on a late-1920s car. It also helps to check the actual wheel width, condition of the rim, and whether the car still carries its expected wheels, since older restorations and long-term ownership changes can leave a Commander wearing something different from its standard tire setup.
Do all 1929 Studebaker Commander sub-models use the same tire size?
Yes. The covered 1929 Studebaker Commander 6 Cyl. and 8 Cyl. sub-models share the same two tire size options: 29X5.50 and 550-19, both in bias-ply construction.
That shared fitment makes sub-model selection less complicated than on vehicles with trim-specific wheel packages. The practical job is confirming which size format is already on the car, making sure the wheels are actually 19-inch rims, and then choosing a tire that supports either a traditional blackwall look or a more formal wide whitewall restoration style.
Choosing the Right Tire
What should I consider when choosing a 550-19 tire for a 1929 Studebaker Commander?
Start with the basics: 550-19 is a primary bias-ply fitment for the 1929 Studebaker Commander and uses a 19-inch rim. Available choices in this size include BFGoodrich Silvertown Classic Bias Ply tires, so the main variables are sidewall style, rim-width compatibility, and the kind of presentation you want the car to have.
A blackwall tire gives a simpler, more understated appearance, while a wide whitewall changes the visual character noticeably. It also helps to compare practical details such as rim width range, weight, and load specification, then confirm that the car's actual wheels, suspension condition, and intended driving use match the tire you are considering.
What sidewall styles are available for 1929 Studebaker Commander tires?
For the 1929 Studebaker Commander in 550-19, the available sidewall styles include Blackwall and Wide Whitewall. Both are bias-ply tires in the BFGoodrich Silvertown Classic Bias Ply line, so the choice is mainly about appearance rather than changing the basic construction type.
That sidewall decision has a strong effect on how the car presents after restoration. Blackwall suits a more restrained vintage look, while a 3.25-inch wide whitewall creates a more formal period-style statement, so it is worth considering the car's paint, trim, and overall restoration direction before settling on one visual approach.
What tire series are available for the 1929 Studebaker Commander?
The available 550-19 products for the 1929 Studebaker Commander are in the BFGoodrich Silvertown Classic Bias Ply series. That means the comparison is less about switching between multiple series and more about selecting the right sidewall treatment within a consistent vintage bias-ply family.
A single series can still involve meaningful choices for a collector car. Since both blackwall and wide whitewall versions are offered, attention should shift to appearance, wheel compatibility, and how the tire will be used, especially if the Commander will see more than occasional display use after the restoration is complete.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Studebaker Commander?
A period-style approach for a 1929 Studebaker Commander starts with staying in one of its primary bias-ply sizes, 29X5.50 or 550-19. Those sizes preserve the vintage sizing language and construction style that suit a late-1920s vehicle much better than a modern-looking tire format would.
From there, the decision usually comes down to how the finished car should look. A blackwall tire creates a restrained traditional presentation, while a wide whitewall adds a more dressy visual effect, and owners pursuing exact historical accuracy should compare that appearance choice against marque references or period photos for their specific car.
Does correct tire fitment matter for a 1929 Studebaker Commander restoration?
Yes, correct tire fitment matters a great deal on a 1929 Studebaker Commander because tire size and construction strongly influence stance, wheel appearance, and the way a restored car reads visually. Using one of the proper bias-ply sizes keeps the tire in step with the car's era and overall design.
Fitment also affects practical details beyond appearance. A tire that matches the intended wheel diameter and suitable rim width helps avoid unnecessary problems with mounting and clearance, and it keeps the restoration focused on a coherent vintage result instead of mixing period bodywork with an obviously mismatched tire profile.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Studebaker Commander?
Yes. A 1929 Studebaker Commander may share the same original tire sizes across its covered sub-models, but later wheel changes, suspension work, brake conversions, or body alterations can change what actually fits the car today.
That matters even when staying with a primary size like 550-19. Any replacement tire should be checked against the wheel diameter already on the car, the wheel width, and available clearance at the fender and steering components, especially if the Commander has been restored more than once or carries parts from another period build.
What should I inspect before driving a 1929 Studebaker Commander on new tires?
Before putting a 1929 Studebaker Commander back on the road with new tires, inspect the wheels for damage, confirm that the rims are the expected 19-inch diameter, and make sure the tires are seated properly and inflated correctly. It is also worth checking lug hardware, valve stems, and basic front-end condition.
A late-1920s car depends on the whole chassis working together, not just the tires. Steering play, weak suspension components, and brake issues can all affect how the car feels on the road, so a careful inspection of tire clearance, alignment-related wear patterns, and overall road readiness is smart before any longer drive.
How should 550-19 tires on a collector 1929 Studebaker Commander be maintained?
550-19 tires on a collector 1929 Studebaker Commander should be maintained with regular pressure checks, visual inspection for cracking or cuts, and periodic tread and sidewall review even if the car is driven only occasionally. Collector-car tires can age quietly, so low mileage does not eliminate the need for inspection.
Storage habits matter almost as much as road use on a vehicle from this era. Keeping the Commander away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and it is wise to look for air loss, flat spotting, or sidewall changes before each outing rather than assuming a seldom-driven car is automatically ready to go.
