The 1929 De Soto 6 came to market at the start of the brand’s brief but important pre-war rise, offering buyers a well-positioned six-cylinder car in an era when tire choice still played a big role in both appearance and road manners. For this model, the primary fitment is a 500-19 bias-ply tire on a 19-inch rim, which places it firmly in the traditional pre-war sizing world. Available choices in that size include blackwall bias-ply tires from Excelsior and Firestone, with differences in tire series and intended character. For a restoration-minded owner, the real focus is keeping the correct size, matching the car’s period presentation, and confirming wheel condition before road use.
Which Tire Size Is Right for The 1929 De Soto 6
The 1929 De Soto 6 uses one primary tire size: 500-19. That size is a bias-ply fitment for a 19-inch rim, and the covered sub-model uses the same specification. With the size already established, the main decision shifts to choosing the right tire series within 500-19 and making sure the wheel and overall condition of the car are ready for safe use.
A 500-19 size uses the older numeric bias-ply system, where the leading number refers to nominal section width in inches and the final number identifies the 19-inch rim diameter. On a 1929 De Soto 6, this is a traditional bias-ply fitment that suits the vehicle’s pre-war wheel and tire character. In this size, available options include Excelsior Comp H and Firestone Dirt Track series tires, both in blackwall form, with differences in tire series and rim-width specification. Choosing within 500-19 comes down to the type of use the car sees and the kind of period-style presentation the owner wants to maintain.
Fitment is straightforward across the covered 1929 De Soto 6 lineup because the listed sub-model uses the same primary tire size. Checking the exact sub-model still helps confirm that the car remains on its intended 19-inch wheel setup before selecting a replacement tire.

Common questions for the 1929 De Soto 6 usually center on its 500-19 tire size, 19-inch rim fitment, bias-ply construction, restoration-minded appearance, and the basic checks worth making before putting a low-use pre-war car back on the road.
Tire Size & Fitment
What tire size fits a 1929 De Soto 6?
The 1929 De Soto 6 uses a 500-19 tire size. This is a numeric bias-ply size and it mounts on a 19-inch rim, which is typical of late-1920s fitment practice. The covered De Soto 6 Base sub-model uses that same size, so the primary fitment question is straightforward.
The important next step is making sure the car still has the correct 19-inch wheels and that no later wheel swap has changed the fitment. Once that is confirmed, selection usually comes down to choosing the appropriate 500-19 bias-ply tire series and checking wheel condition, tube setup if applicable, and overall road-readiness.
What size rim does a 1929 De Soto 6 use?
The 1929 De Soto 6 uses a 19-inch rim with its 500-19 tire size. That rim diameter is part of the tire size itself, and the available 500-19 products for this application are built around that 19-inch wheel requirement rather than a modern passenger-car rim size.
Rim diameter should be verified on the actual car before ordering tires, especially on an older vehicle that may have seen wheel changes over many decades. Rim width matters too, since available 500-19 products are associated with specific rim-width measurements, so checking both diameter and width helps avoid preventable fitment issues.
Does the 1929 De Soto 6 Base use the same tire size?
Yes. The 1929 De Soto 6 Base uses the same 500-19 bias-ply tire size as the main vehicle fitment. That means there is no separate primary size to sort through for the covered sub-model, and the fitment remains centered on the same 19-inch rim diameter.
Even with shared sizing, an owner should still inspect the actual wheel setup on the car before replacing tires. Older restorations, long-term storage, and wheel substitutions can change what is mounted today, so confirming the wheel dimensions and the condition of rims, fasteners, and tires is still a sensible part of the process.
Choosing the Right Tire
What should I consider when choosing a 500-19 tire for a 1929 De Soto 6?
Start with the correct size and construction: the 1929 De Soto 6 uses a 500-19 bias-ply tire on a 19-inch rim. After that, compare the available tire series, intended use, rim-width specification, weight, and overall appearance so the tire matches the way the car is being restored, displayed, or driven.
A pre-war car often benefits from a more deliberate choice than a simple size match. One owner may want a traditional blackwall presentation for a restoration-oriented look, while another may be focused on a specialized tire character within the same size. The wheel setup and the car’s planned use should guide the final decision.
What brands offer tires for the 1929 De Soto 6?
Available 500-19 tires for the 1929 De Soto 6 include products from Excelsior and Firestone. Those choices give the owner more than one brand path within the correct size, while still staying within the traditional bias-ply construction used on this pre-war De Soto application.
Brand choice should be weighed alongside tire series, intended character, rim-width compatibility, and the type of use the car will see. Rather than treating brand alone as the deciding factor, it makes more sense to compare how each 500-19 option aligns with the car’s wheel setup and the owner’s appearance or driving goals.
What tire series are available for the 1929 De Soto 6?
The 1929 De Soto 6 has 500-19 tire options in at least two distinct series: Excelsior Comp H and Firestone Dirt Track. Both are bias-ply blackwall tires, but the series names indicate that they are not simply identical versions of the same product within the size.
Series differences matter because they can shape the tire’s character and the type of vehicle use it best suits. A buyer comparing 500-19 options should look beyond the size code and review the product details carefully, especially rim-width compatibility, tire attributes, and whether the car is being prepared for display, occasional touring, or another purpose.
Restoration & Appearance
Which tire should I choose for a period-style 1929 De Soto 6?
A period-style starting point for a 1929 De Soto 6 is the correct 500-19 bias-ply size on a 19-inch rim. Staying with the proper size and traditional bias-ply construction helps preserve the visual proportions expected on a late-1920s six-cylinder car, especially when the goal is a restoration-oriented presentation.
Within that size, appearance still comes down to the specific tire series and how the finished car is meant to look and be used. Exact originality claims should be checked against marque references, period photographs, or restoration documentation, but the right size and construction remain the foundation of a convincing pre-war tire presentation.
Does correct tire fitment matter for a 1929 De Soto 6 restoration?
Yes, correct tire fitment matters a great deal on a 1929 De Soto 6 restoration. The 500-19 size and 19-inch rim are part of the car’s visual stance, wheel opening fill, and overall pre-war character, so using the proper fitment helps the finished vehicle look proportionate and historically appropriate.
Restoration value is not only about appearance. Proper sizing also supports sensible wheel compatibility and reduces the chance of introducing avoidable clearance or mounting issues. Before the car returns to active use, inspect the wheels carefully, confirm the tires match the intended setup, and make sure age or storage damage has not compromised any existing components.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 De Soto 6?
Yes. Even though the standard fitment is a 500-19 bias-ply tire on a 19-inch rim, modifications can change what actually works on the car. Wheel swaps, changes in rim width, brake conversions, suspension alterations, or body repairs can all affect how a replacement tire mounts and clears.
That is especially important with a pre-war vehicle, where decades of repairs or updates may not be immediately obvious. Measuring the actual wheels on the car and checking clearance at the fenders, steering components, and suspension is a smart step before replacing tires, particularly if the De Soto has not remained in a stock-style configuration.
What should I inspect before driving a 1929 De Soto 6 on new tires?
Before road use, inspect the wheel condition, mounting surfaces, lug hardware, valve stems, and the overall condition of the tires themselves. On a 1929 De Soto 6, it also makes sense to confirm the 19-inch wheel setup, check for sidewall damage, and look for signs of age, cracking, cuts, or air loss.
A low-use collector car often needs more than fresh tires to be truly road-ready. Steering, suspension, brakes, and wheel bearings should all be examined, since old components can affect how the car tracks and how the tires wear. A careful inspection helps the De Soto return to service with fewer surprises on the first drive.
How should 500-19 tires on a collector 1929 De Soto 6 be maintained?
500-19 tires on a collector 1929 De Soto 6 should be kept properly inflated, inspected regularly, and protected from long periods of heat, sunlight, moisture, and ozone exposure. Because collector cars often spend more time parked than driven, sidewall condition and age-related deterioration deserve as much attention as tread wear.
Driving the car occasionally can help reveal air loss, vibration, or handling changes before they become larger problems, but long storage still calls for routine checks. Keeping the wheels clean, monitoring tire condition at each service interval, and watching for cracks, bulges, or flat spotting will help preserve both safety and presentation.
