1937 De Soto 6 Air Stream Tires

A 1937 De Soto 6 Air Stream uses either 650-16 or 600-16, both in bias-ply construction on 16-inch rims. The 7 Passenger model uses 650-16, while the S-3 uses 600-16, so there is not one universal size across every covered version of the car.

The most important step is identifying the exact sub-model before ordering tires. Once that is settled, check the actual wheel diameter and width on the car, especially if it has been restored long ago or changed over the years, since a correct size still needs to match the wheel and body clearance available.

The 1937 De Soto 6 Air Stream uses a 16-inch rim with either of its primary tire sizes. Both 650-16 and 600-16 are built around that same wheel diameter, so the change between sizes is tied to sub-model application rather than a switch to a different rim diameter.

Wheel diameter is only the first part of the fitment check on a prewar car. Rim width also matters, and the tire options in these sizes can call for different width ranges, so it is smart to confirm the actual wheels on the car before choosing between passenger-style whitewalls, blackwalls, or more utility-oriented tread patterns.

No. The 1937 De Soto 6 Air Stream sub-models covered here do not all use the same tire size. The 7 Passenger version uses 650-16, while the S-3 uses 600-16, and both are bias-ply tires designed for 16-inch wheels.

That difference affects more than the number molded into the sidewall. It changes the tire’s nominal section width, and it can influence how the car sits visually and how the tire matches the wheel already installed, so the sub-model should be confirmed before focusing on whitewall width, brand preference, or tread style.

Start with the exact sub-model, since the 1937 De Soto 6 Air Stream uses 650-16 for the 7 Passenger model and 600-16 for the S-3. Both are bias-ply fitments, so the next considerations are wheel compatibility, sidewall style, tire series, and whether the tire is aimed at passenger-car presentation or a more utility-oriented tread.

Appearance matters on a car from this era, but the wheel setup matters just as much. A blackwall, wide whitewall, or double-whitewall can change the look substantially, and some products also differ in rim-width guidance, load specification, and general character, so the best comparison is always made within the correct primary size.

The available sidewall styles for 1937 De Soto 6 Air Stream tires include blackwall and wide whitewall in both primary sizes, with double-whitewall options also appearing in 600-16. That gives owners room to choose between a restrained presentation and a brighter prewar look without leaving the correct bias-ply size family.

Sidewall style should be chosen with the car’s overall finish and restoration direction in mind. A whitewall can emphasize the car’s period character, while a blackwall gives a simpler, more understated appearance, and the right choice should still be paired with the proper size and wheel-width compatibility for the exact sub-model.

Brands available in the 1937 De Soto 6 Air Stream’s primary sizes include BFGoodrich, Coker Classic, Firestone, Garfield, Lester, Goodyear, Excelsior, STA, Tornel, Avon, Ford Script, and Camac. Brand availability varies by size, so one sub-model may have a different mix of choices than the other even though both use 16-inch bias-ply tires.

Brand choice is best treated as part of a broader comparison rather than the first filter. Once the proper size is confirmed, compare sidewall treatment, tire series, rim-width specification, and the kind of use the car will actually see, especially if the vehicle is driven occasionally rather than displayed as a restoration piece.

A period-style 1937 De Soto 6 Air Stream should begin with the correct primary bias-ply size for the exact sub-model: 650-16 for the 7 Passenger model or 600-16 for the S-3. From there, the choice usually comes down to whether the car looks best with a blackwall or one of the available whitewall treatments.

For many restorations, the goal is visual balance rather than chasing one universal answer. Tire series, tread character, and sidewall treatment all shape the finished look, and owners pursuing exact historical accuracy should compare their selection against marque literature, surviving examples, or restoration references specific to their De Soto.

Yes, correct tire fitment matters a great deal on a 1937 De Soto 6 Air Stream restoration because the tire is a highly visible part of the car’s stance and period character. Using the proper bias-ply size for the right sub-model helps maintain the visual proportion the car was built around.

Fitment also affects how naturally the tire sits on the wheel and within the fender opening. Even when a tire looks close at a glance, the wrong size or an unsuitable wheel width can change the car’s presentation, so restoration-minded owners should confirm both the sub-model application and the actual wheel setup before choosing a tire.

Yes, modifications can affect tire fitment on a 1937 De Soto 6 Air Stream even when the tire size itself is correct for the sub-model. Changes to wheels, suspension height, brake components, or body clearance can alter how a 650-16 or 600-16 bias-ply tire sits and turns within the available space.

Older cars often pick up replacement wheels or chassis updates over time, so the actual setup should be inspected rather than assumed. Wheel width, offset-related positioning, steering lock clearance, and fender space all deserve attention before mounting new tires, particularly if the car has been restored, lowered, or otherwise altered in the past.

Before driving a 1937 De Soto 6 Air Stream on new tires, inspect the wheels for correct diameter and sound condition, verify that the tires are seated properly, and confirm there is no interference at the fenders or steering components. Tire pressure should also be checked carefully before the car goes back into regular road use.

A collector-era car benefits from a broader walkaround as well. Look at suspension condition, wheel fasteners, visible brake components, and any signs of uneven ride height, then recheck the tires after the first few miles for clearance marks, pressure loss, or settling issues that could point to a wheel or fitment problem.

Collector-car tires in 650-16 or 600-16 should be maintained with regular pressure checks, visual inspections, and clean storage habits. Bias-ply tires on a 1937 De Soto 6 Air Stream deserve close attention for sidewall cracking, cuts, bulges, tread wear, and any sign that the car has been sitting long enough to affect tire condition.

Long periods of storage can be as important as mileage on a prewar car. Keeping the De Soto away from prolonged sun, heat, moisture, and ozone sources helps preserve the tires, and it is wise to inspect them before every meaningful drive rather than relying on tread depth alone as the measure of roadworthiness.
