1952 De Soto S 15-6 Tires

A 1952 De Soto S 15-6 uses either 820-15 or 760-15, both in bias-ply construction on 15-inch rims. The 8 Passenger model uses 820-15, while the Wagon uses 760-15, so there is not one universal size across every covered version of this De Soto.

The practical step is to confirm the exact sub-model before choosing a tire. Once the correct size is established, selection usually comes down to sidewall style, tire series, and whether to stay with a traditional bias-ply tire or consider one of the available radial-equivalent sizes after checking wheel width and vehicle clearance.

Both primary tire sizes for the 1952 De Soto S 15-6 use a 15-inch rim diameter. That applies to the 820-15 and 760-15 fitments, so the difference between the two sizes is tied to sub-model application rather than a change in wheel diameter.

Rim diameter is only part of the fitment picture, especially on a collector car that may have seen wheel changes over the years. It is still worth confirming the actual wheel on the car, along with wheel width, before choosing between bias-ply replacements or one of the radial-equivalent sizes that can also be considered for these De Soto applications.

No. The 1952 De Soto S 15-6 has sub-model-specific tire sizing. The 8 Passenger version uses 820-15, while the Wagon uses 760-15, and both are traditional bias-ply sizes mounted on 15-inch rims.

That distinction matters because a tire that is correct in one De Soto configuration is not automatically the right starting point for another. Before comparing brands, whitewall widths, or radial alternatives, match the tire size to the sub-model first, then verify the actual wheel and overall clearance if the car has replacement wheels or suspension changes.

On the 1952 De Soto S 15-6, 820-15 is a primary bias-ply tire size. It is the original-style construction format used for the 8 Passenger fitment and it remains the main reference point when choosing a traditional tire for that version of the car.

Bias-ply selection usually appeals to owners who want a period-style look and driving character. A radial equivalent can be considered, but that does not change the fact that 820-15 itself is a bias-ply fitment, so any construction change should be checked against wheel width, physical clearance, and the overall appearance goal for the De Soto.

Radial equivalents for 760-15 include 215R15 as an 80-series metric radial, P225/75R15 as a 75-series P-metric radial, P235/70R15 as a 70-series P-metric radial, and 760R15 as a bias-look radial. These are alternative sizing formats associated with the 760-15 bias-ply fitment.

The main difference between those choices is the sizing convention and profile presentation, with the bias-look radial aimed at a more traditional appearance. A recommended rim-width range of 6-8 inches is associated with these equivalents, but wheel width, overall dimensions, and clearance on the specific Wagon should still be checked before moving away from the primary bias-ply size.

Start by matching the radial equivalent to the De Soto's actual primary size and sub-model. For 820-15, the available radial equivalents are 235R15, P235/75R15, P255/70R15, and 820R15. For 760-15, they are 215R15, P225/75R15, P235/70R15, and 760R15.

After that, verify the wheel diameter and wheel width on the car, then compare the radial choice against fender, steering, and suspension clearance. A collector car may also have older replacement wheels or altered ride height, so the safest approach is to confirm the actual setup before changing construction rather than assuming an equivalent size will automatically suit every De Soto.

An 820-15 tire for a 1952 De Soto S 15-6 should first match the correct sub-model, since that size belongs to the 8 Passenger version. From there, the main points of comparison are bias-ply construction, sidewall style, tire series, brand, and the wheel-width specifications used by the individual product.

Appearance often drives the final decision in this size because blackwall, narrow whitewall, and wide whitewall choices can change the car's overall presentation. It also helps to compare practical details such as rim-width range, load figures where shown, and whether the intended use is restoration-minded driving or something more specialized within the available 820-15 selection.

Sidewall choices for the 1952 De Soto S 15-6 include blackwall, narrow whitewall, and wide whitewall depending on the tire size and product selected. The 820-15 range includes all three presentations, while the 760-15 selection focuses on narrow whitewall and wide whitewall styles.

That makes sidewall treatment one of the biggest visual decisions on this De Soto, especially for owners aiming for a strong early-1950s look. The best choice depends on the exact sub-model, the tire size it uses, and whether the car is being finished with a restrained blackwall appearance or a more formal whitewall presentation.

Tires for the 1952 De Soto S 15-6 are available from BFGoodrich, Firestone, US Royal, Universal Vintage Tire, Avon, Coker Classic, and Goodyear across the two primary sizes. Brand availability depends on whether the car uses 820-15 or 760-15, so the correct sub-model and size should be confirmed first.

Brand choice is most useful as part of a broader comparison rather than a shortcut. Once the correct size is established, compare each option by tire series, sidewall presentation, and wheel-width specification, since those details usually have more impact on how the tire suits the car than the brand name alone.

A period-style starting point for a 1952 De Soto S 15-6 is the correct primary bias-ply size for the exact sub-model: 820-15 for the 8 Passenger model and 760-15 for the Wagon. Staying with the original construction style preserves the visual proportions and traditional presentation associated with this early-1950s De Soto.

The finer decision usually comes down to sidewall treatment and the character of the tire series. Whitewall width can make a noticeable difference in the finished look, so owners pursuing close historical accuracy should compare the car against marque references, period photos, or restoration documentation before settling on a specific sidewall style.

Tire construction has a clear effect on how a restored 1952 De Soto S 15-6 presents. A bias-ply tire keeps the car in its original-era sizing language and visual character, while a radial equivalent can change the overall impression even when it serves as a legitimate alternative in the same general fitment range.

That matters most on a large, formal postwar car where sidewall shape and whitewall presentation are part of the styling. Owners who want a traditional restoration look often begin with the correct bias-ply size, while those planning more regular road use may consider a bias-look radial after confirming wheel compatibility and deciding how much visual change is acceptable.

Yes. Modifications can affect tire fitment on a 1952 De Soto S 15-6 even when the car starts with the correct 820-15 or 760-15 size family. Replacement wheels, different wheel widths, suspension changes, or body and brake updates can all alter the space available around the tire.

That is especially important when considering radial equivalents, since the car may no longer match its original wheel and suspension setup. A careful check of wheel diameter, wheel width, steering travel, and fender clearance will do more to prevent fitment surprises than relying on size designation alone, particularly on an older vehicle with an unknown modification history.

Before driving a 1952 De Soto S 15-6 on new tires, inspect the wheels for correct diameter and condition, confirm the tires are properly seated, and verify inflation pressure against the tire's requirements. It is also smart to look at suspension and steering components, since an older car can have wear that becomes more noticeable once fresh tires are installed.

A short local test drive is the right next step before any longer trip. Pay attention to clearance at full steering lock, any pull or vibration, and whether the tires show signs of rubbing after the first miles. Collector cars often reveal wheel, alignment, or brake issues only after they return to regular road use.

Collector-car tires in 820-15 and 760-15 sizes should be maintained with regular pressure checks, visual inspection, and careful storage. Look for cracking, bulges, cuts, uneven wear, or slow air loss, and do not assume low mileage means the tires are ready for road use without a close inspection.

Storage conditions matter almost as much as miles on a vehicle like a 1952 De Soto S 15-6. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires, while periodic movement and routine checks can catch age-related problems before they turn into road-use issues on a larger, heavier vintage car.
