The 1942 De Soto 6 Deluxe & Custom came from a brief, interrupted model year at the end of De Soto’s prewar passenger-car era, when roomy American sedans still rode on tall 16-inch tires with a distinctly traditional stance. For today’s owner, tire choice is tied closely to body configuration, because this model family uses either 650-16 or 6.25-16 bias-ply fitment depending on sub-model. That keeps the decision centered on correct size first, then on presentation through blackwall or wide whitewall styles and the available tire series. For a restoration-minded car, the right tire should support both the car’s proportions and the way it will actually be driven.
Which Tire Size Is Right for The 1942 De Soto 6 Deluxe & Custom
The 1942 De Soto 6 Deluxe & Custom uses two primary tire sizes, and both are bias-ply tires built for 16-inch rims. The key step is identifying the exact sub-model first, because the 7 Passenger configuration uses a different size than the Base model. Once size is confirmed, the decision shifts to sidewall appearance, tire series, and whether the car is being finished for road use, touring, or a more restoration-oriented presentation.
In a 650-16 numeric bias-ply size, the 6.50 designation refers to the tire’s nominal section width in inches, while 16 identifies the rim diameter. This is a traditional bias-ply fitment that suits the tall, upright proportions expected on a prewar-era De Soto and is used on the 7 Passenger sub-model. Product choices in this size include blackwall and wide whitewall treatments from brands such as BFGoodrich, Firestone, Goodyear, Garfield, Lester, Coker Classic, Excelsior, STA, and Tornel across several tire series. It is the size to evaluate when maintaining the larger passenger-car fitment associated with that specific configuration.
In a 6.25-16 numeric bias-ply size, the first number indicates an approximate 6.25-inch nominal section width and the 16 identifies the wheel diameter. This is also a traditional bias-ply fitment, but it serves a different 1942 De Soto 6 Deluxe & Custom sub-model than 650-16, so it should not be treated as interchangeable without confirming the actual car. The practical role of this size is preserving the correct overall fitment family for the Base model. Before choosing any tire in this size, confirm the car’s sub-model and make sure the installed wheels still match the intended 16-inch setup.
Tire fitment changes by sub-model on the 1942 De Soto 6 Deluxe & Custom, even though both versions use 16-inch bias-ply construction. Checking the exact sub-model matters first, because the correct tire size depends on whether the car is the 7 Passenger version or the Base model.

1942 De Soto 6 Deluxe & Custom (7 Passenger)
The 1942 De Soto 6 Deluxe & Custom (7 Passenger) uses the 650-16 bias-ply tire size. That makes tire selection less about comparing multiple primary fitments and more about choosing the right blackwall or wide whitewall presentation, brand, and tire series within the proper size.
The 1942 De Soto 6 Deluxe & Custom Base uses the 6.25-16 bias-ply tire size rather than the larger 650-16 used elsewhere in this model family. For that reason, the first step is confirming the car’s actual sub-model and wheel setup before focusing on appearance or restoration style.
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.

These 1942 De Soto 6 Deluxe & Custom tire FAQs focus on the two primary sizes, 16-inch rim fitment, bias-ply selection, sidewall appearance, and the checks that matter before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1942 De Soto 6 Deluxe & Custom?
A 1942 De Soto 6 Deluxe & Custom uses either 650-16 or 6.25-16, and both are bias-ply tire sizes for 16-inch rims. The 7 Passenger sub-model uses 650-16, while the Base model uses 6.25-16, so there is not one single size shared across every version of this car.
The practical step is to confirm the exact sub-model before choosing a tire. Cars that have been stored for years, restored, or changed with replacement wheels should also have the installed rim diameter checked, since both sizes belong to the same 16-inch wheel family but serve different fitment roles on this De Soto.
What size rim does a 1942 De Soto 6 Deluxe & Custom use?
The 1942 De Soto 6 Deluxe & Custom uses a 16-inch rim with its primary tire fitments. Both 650-16 and 6.25-16 are built around that same 16-inch wheel diameter, so the fitment difference between sub-models is the tire size itself rather than a change to a different rim diameter.
Rim diameter is only one part of the fitment picture, so it helps to verify the actual wheels on the car before ordering tires. A collector car may have replacement rims, and wheel width can also matter when comparing available products, especially if the goal is to keep the car’s stance and appearance in line with its period-style setup.
Do all 1942 De Soto 6 Deluxe & Custom sub-models use the same tire size?
No. The 1942 De Soto 6 Deluxe & Custom has sub-model-specific tire fitment. The 7 Passenger version uses 650-16 bias-ply tires, while the Base model uses 6.25-16 bias-ply tires, even though both are intended for 16-inch rims.
That distinction matters because a tire that is correct for one sub-model should not be assumed correct for the other. Before selecting sidewall style, brand, or tire series, verify how the car is configured and check that the current wheels still match the intended setup, particularly on older vehicles that may have seen restoration or parts changes over time.
Choosing the Right Tire
What should I consider when choosing a 650-16 tire for a 1942 De Soto 6 Deluxe & Custom?
Start by confirming that the car is the 7 Passenger sub-model, since 650-16 is not the tire size for every 1942 De Soto 6 Deluxe & Custom. In this size, the main choices are bias-ply tire series, sidewall treatment, and whether the tire’s character suits a passenger-car presentation or a more utility-oriented tread style.
Appearance often drives the final decision, especially between blackwall and wide whitewall versions. It also helps to compare wheel-width guidance where available, along with load figures such as 1580 pounds at 32 psi or 1610 pounds at 45 psi on certain products, so the selected tire matches the wheel and the intended use of the car.
What sidewall styles are available for 1942 De Soto 6 Deluxe & Custom tires?
The available 650-16 tire choices for the 1942 De Soto 6 Deluxe & Custom include blackwall and wide whitewall sidewall styles. Those two looks create very different visual results, with blackwall giving a plainer, more understated presentation and wide whitewall giving the car a more formal, restoration-oriented period appearance.
Sidewall choice should come after size and sub-model are confirmed, not before. Once the fitment is right, the sidewall becomes a styling decision that affects how the De Soto sits visually against its fenders and wheel covers, so it is worth matching the tire’s appearance to the level of authenticity and road presence the owner wants.
What brands offer tires for the 1942 De Soto 6 Deluxe & Custom?
In 650-16, the 1942 De Soto 6 Deluxe & Custom has offerings from BFGoodrich, Coker Classic, Firestone, Garfield, Lester, Goodyear, Excelsior, STA, and Tornel. The available products span several bias-ply series, including traditional passenger-car styles as well as truck or military-style tread patterns within the same size family.
Brand choice is only one part of the decision, because series style, sidewall treatment, rim-width guidance, and intended use can matter just as much. A buyer restoring a formal passenger car may lean toward a traditional blackwall or wide whitewall presentation, while a more specialized setup might call for a different tread character within the proper size.
Restoration & Appearance
Which tire should I choose for a period-style 1942 De Soto 6 Deluxe & Custom?
A period-style 1942 De Soto 6 Deluxe & Custom should begin with the correct primary size for the exact sub-model: 650-16 for the 7 Passenger version or 6.25-16 for the Base model. From there, a bias-ply tire is the construction that matches the car’s original-era tire character and preserves its traditional side profile.
The final choice usually comes down to how formal or restrained the finished car should look. Blackwall and wide whitewall options create different visual impressions, so buyers seeking a highly authentic restoration should compare those details against marque references, period photography, and vehicle-specific historical guidance before settling on a presentation.
How does tire construction affect the appearance of a restored 1942 De Soto 6 Deluxe & Custom?
On a restored 1942 De Soto 6 Deluxe & Custom, tire construction strongly affects the car’s overall presentation. A bias-ply tire carries the tall, upright profile and traditional look most owners expect on a prewar-era American sedan, which is why correct bias-ply sizing remains such an important starting point on this model family.
Appearance is not just about the sidewall color or whitewall width. The tire’s shape, shoulder profile, and overall visual stance influence how naturally the car sits within its fenders, so restoration-minded buyers usually want the proper size and construction settled first, then refine the look through brand, tread style, and sidewall treatment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1942 De Soto 6 Deluxe & Custom?
Yes. Even though the 1942 De Soto 6 Deluxe & Custom uses 16-inch bias-ply fitment, changes such as replacement wheels, altered wheel width, suspension work, or body repairs can affect how a tire fits and clears. That matters even more here because the model family already has two different primary tire sizes by sub-model.
A car that still appears stock should not automatically be assumed to have its original wheel setup. Checking wheel diameter, wheel width, and visible clearance at the fenders and steering components helps avoid choosing the wrong tire for the car’s current configuration, especially on older vehicles that may have changed hands many times.
What should I inspect before driving a 1942 De Soto 6 Deluxe & Custom on new tires?
Before driving a 1942 De Soto 6 Deluxe & Custom on new tires, inspect the wheels, valve stems, lug hardware, and the condition of the suspension and steering components. The tires themselves should be checked for proper inflation, even seating on the rim, and any signs of rubbing once the car is set down and turned lock to lock.
A collector car often needs more than a simple tire change before it is truly road-ready. Brake condition, alignment, and old wheel damage can all affect how the car behaves on fresh bias-ply tires, so a careful post-installation check and a short, cautious test drive are smart steps before any longer use.
How should 650-16 or 6.25-16 tires on a collector 1942 De Soto 6 Deluxe & Custom be maintained?
Collector-car tires in 650-16 or 6.25-16 should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Bias-ply tires on an infrequently driven 1942 De Soto 6 Deluxe & Custom should also be watched for sidewall cracking, flat spotting after long periods of sitting, cuts, bulges, or slow air loss.
Good maintenance is especially important on a car that spends more time parked than driven. Keeping the De Soto away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the rubber, and periodic inspection remains important even when tread wear looks minimal because age and storage conditions matter on vintage tires.
