The 1947 De Soto 6 Deluxe came to market just after World War II, when American automakers were returning to civilian production and full-size six-cylinder sedans were expected to deliver comfort, dignity, and dependable road manners. That makes tire choice more than a simple replacement decision, because the car’s stance and driving character are closely tied to its original-style sizing. This De Soto uses a 6.50-15 bias-ply tire on a 15-inch rim. The focus is less about sorting through multiple fitment sizes and more about choosing the right period-style tire within that size. For a restoration-minded owner, appearance, construction, and wheel compatibility all deserve a careful look before the car goes back on the road.
Which Tire Size Is Right for The 1947 De Soto 6 Deluxe
The 1947 De Soto 6 Deluxe uses one primary tire size: 6.50-15. That fitment is a bias-ply tire on a 15-inch rim, and it carries across the covered sub-model here, so the real decision is choosing the right tire within that size and staying mindful of restoration goals, appearance, and wheel compatibility.
A 6.50-15 is a vintage numeric bias-ply size in which the 6.50 refers to the nominal section width in inches and the 15 identifies the rim diameter. On a 1947 De Soto 6 Deluxe, that sizing reflects the postwar full-size American passenger-car fitment the chassis was built around. Bias-ply construction also contributes to the traditional look many restoration-minded owners want on a car of this era. Choosing this size keeps the selection centered on proper vintage-style fitment, so the next step is confirming the wheel itself is the correct 15-inch setup and matching the tire to the car’s intended use and presentation.
Fitment is straightforward for the covered 1947 De Soto 6 Deluxe sub-models, because the tire size remains consistent. Checking the exact sub-model still helps confirm that the car stays on the expected 6.50-15 bias-ply fitment and 15-inch wheel setup.

1947 De Soto 6 Deluxe Base
The 1947 De Soto 6 Deluxe Base uses the same 6.50-15 bias-ply fitment as the overall model listing. That keeps tire selection focused on finding the right period-style replacement within that size and confirming the car still has the proper 15-inch wheels before installation.
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.
Frequently Asked Questions
These 1947 De Soto 6 Deluxe tire FAQs focus on the 6.50-15 fitment, 15-inch wheel compatibility, bias-ply construction, restoration-minded tire selection, and the condition checks that matter before putting a low-use postwar car back on the road.
Tire Size & Fitment
What tire size fits a 1947 De Soto 6 Deluxe?
The 1947 De Soto 6 Deluxe uses a 6.50-15 tire size. This is a vintage numeric bias-ply fitment, and it is paired with a 15-inch rim on the covered application for this vehicle.
That means the first step is not choosing between several primary sizes, but confirming the car still has the correct 15-inch wheels and selecting a proper 6.50-15 tire within that fitment. If the car has been modified over the years, wheel diameter and width should be verified before mounting new tires.
What size rim does a 1947 De Soto 6 Deluxe use?
The 1947 De Soto 6 Deluxe uses a 15-inch rim with its 6.50-15 tire size. The rim diameter matters because vintage tire sizing is tied directly to the wheel diameter, and a 15-inch tire must be matched with a 15-inch wheel.
Wheel confirmation is especially important on an older collector car that may have seen replacement wheels at some point in its life. Checking the actual wheel diameter before ordering tires helps avoid fitment mistakes and keeps the selection process focused on the correct vintage-size tire for the car.
Does the 1947 De Soto 6 Deluxe Base use the same tire size?
Yes. The 1947 De Soto 6 Deluxe Base uses the same 6.50-15 bias-ply tire size as the main 1947 De Soto 6 Deluxe fitment covered here. That keeps sub-model fitment simple and avoids the need to sort between multiple primary sizes.
Even with shared fitment, it is still smart to inspect the wheel setup on the actual car before purchasing tires. A postwar sedan that has been stored, restored, or modified in the past may no longer be wearing its expected wheels, and that is the practical detail worth checking before moving ahead.
Choosing the Right Tire
What should I consider when choosing a 6.50-15 tire for a 1947 De Soto 6 Deluxe?
Start with the correct primary fitment: 6.50-15 on a 15-inch wheel, with bias-ply construction matching the original-style sizing approach for this De Soto. Once that is confirmed, the key decision becomes how closely the tire should support the car’s restoration goals, traditional appearance, and expected road use.
A touring car that is driven occasionally may call for different priorities than one being finished for show presentation. Wheel condition, proper diameter, and the overall condition of the suspension and steering should also be part of the decision, because the right tire choice works best when the rest of the chassis is equally ready.
How do I choose between the available 6.50-15 tires for a 1947 De Soto 6 Deluxe?
Choosing between 6.50-15 tires for a 1947 De Soto 6 Deluxe usually comes down to staying within the correct size while comparing the tire’s style, construction, and how well it suits the car’s intended presentation. On a postwar sedan like this, appearance can matter almost as much as size because the tire contributes heavily to the car’s stance.
It helps to decide early whether the goal is a restoration-oriented look, a dependable road-ready setup, or a balance between the two. Confirming the wheel dimensions and inspecting for any past modifications keeps the comparison honest, since even the right nominal size still needs to suit the actual car in front of you.
What does 6.50-15 mean on a 1947 De Soto 6 Deluxe?
On a 1947 De Soto 6 Deluxe, 6.50-15 is a numeric bias-ply size. The 6.50 refers to the nominal section width in inches, while the 15 identifies the wheel diameter the tire is built to mount on.
That older sizing format is common on vintage American cars and can look unfamiliar to buyers used to modern metric radial sizes. Understanding the code helps keep the search focused on the proper vintage fitment and makes it easier to verify that the car still has the correct 15-inch wheels before purchasing new tires.
Restoration & Appearance
Which tire should I choose for a period-style 1947 De Soto 6 Deluxe?
A period-style starting point for a 1947 De Soto 6 Deluxe is the correct 6.50-15 bias-ply fitment on a 15-inch wheel. That keeps the tire size aligned with the car’s postwar design era and preserves the traditional visual proportion that matters on a full-size sedan of this type.
For many restorations, the goal is to maintain the right overall stance rather than chase a modernized look. Buyers who want exact historical authenticity beyond size and construction should still compare tire details against marque references, restoration photos, or other vehicle-specific documentation before making a final appearance-driven choice.
Does correct tire fitment matter for a 1947 De Soto 6 Deluxe restoration?
Yes, correct tire fitment matters a great deal on a 1947 De Soto 6 Deluxe restoration. The 6.50-15 size affects not only wheel compatibility, but also the car’s overall posture, wheel opening fill, and the traditional visual balance expected from a postwar De Soto sedan.
Using the proper vintage-style size helps the finished car look coherent and avoids a mismatched appearance that can come from incorrect proportions. It also keeps the restoration process grounded in practical fitment, since wheel diameter, chassis clearance, and the actual condition of the suspension all influence how the final setup will sit and drive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1947 De Soto 6 Deluxe?
Yes. Modifications can affect tire fitment on a 1947 De Soto 6 Deluxe even when the intended tire size remains 6.50-15. Changes such as aftermarket wheels, altered ride height, brake upgrades, or bodywork repairs can all influence wheel diameter, width, and available clearance.
That is why the actual car should be checked before mounting new tires, especially if its history is not fully known. Clearance at the fenders, suspension, and steering components deserves attention, and wheel dimensions should be verified rather than assumed simply because the vehicle started life with a 15-inch bias-ply fitment.
What should I inspect before driving a 1947 De Soto 6 Deluxe on new tires?
Before driving a 1947 De Soto 6 Deluxe on new tires, inspect the wheels for damage or excessive rust, confirm proper air pressure, and make sure the tires seat correctly on the rims. The suspension and steering should also be checked for worn components that could affect how a vintage car tracks on the road.
A fresh set of tires cannot compensate for loose steering parts, poor alignment, or neglected wheel hardware. It also helps to recheck clearance after installation by turning lock to lock and looking for any rubbing, especially on a collector vehicle that may have seen repair work or long periods of storage.
How should 6.50-15 tires on a collector 1947 De Soto 6 Deluxe be maintained?
6.50-15 tires on a collector 1947 De Soto 6 Deluxe should be maintained with regular pressure checks, visual inspections, and careful storage habits. On a low-use vintage car, sidewall cracking, tread separation, flat spotting, bulges, and slow air loss deserve attention even when the car is driven only occasionally.
Good maintenance also means keeping the car away from prolonged sunlight, moisture, and ozone sources during storage whenever possible. Occasional inspections of wheel condition and chassis alignment are worthwhile too, because a postwar car that sits for long stretches can develop issues that are not obvious until it returns to road use.
