The 1940 Chrysler Windsor 25 belongs to a prewar Chrysler era when smooth ride quality, dignified styling, and substantial road presence mattered as much as outright performance. Owners restoring or maintaining one today usually want a tire that supports that full-bodied character without looking out of place on a late-1930s, early-1940s sedan. The 1940 Chrysler Windsor 25 uses a 6.25-16 bias-ply tire, which keeps the fitment rooted in the sizing and construction style of its period. That makes the main decision less about multiple fitments and more about choosing a tire that suits the car's intended appearance and road use. Careful wheel, condition, and setup checks remain important before any replacement goes into service.
Which Tire Size Is Right for The 1940 Chrysler Windsor 25
The 1940 Chrysler Windsor 25 uses one primary tire size: 6.25-16, a bias-ply fitment on a 16-inch rim. The covered Windsor 25 sub-model shares that same sizing, so the main decision is choosing the right tire within that format and confirming that the wheels on the car still match the original-style diameter and width before replacement.
In the 6.25-16 size, the first number refers to the tire's nominal section width in inches, while the 16 identifies the wheel diameter in inches. This is a numeric bias-ply format, the type of sizing and construction commonly associated with prewar American passenger cars like the 1940 Chrysler Windsor 25. For this Chrysler, the choice within 6.25-16 usually centers on maintaining the proper period-style look and staying with the construction the car was built around. It is also wise to confirm the actual wheel setup on the vehicle, especially if the car has been modified or fitted with replacement wheels over the years.
Tire fitment for the covered 1940 Chrysler Windsor 25 sub-model is straightforward. The key benefit of checking the exact sub-model is simply confirming that the car stays with the correct 6.25-16 bias-ply sizing on a 16-inch rim.

Frequently Asked Questions
These FAQs focus on the 1940 Chrysler Windsor 25 tire size, 16-inch rim fitment, bias-ply construction, restoration-minded selection, and the wheel, condition, and safety checks that matter before driving a prewar Chrysler.
Tire Size & Fitment
What tire size fits a 1940 Chrysler Windsor 25?
The 1940 Chrysler Windsor 25 uses a 6.25-16 tire. This is a numeric bias-ply size, and it is the primary fitment for the model covered here, including the 1940 Chrysler Windsor 25 6 Cyl. sub-model.
That means the first step is not sorting through several original sizes, but confirming that the car still has 16-inch wheels and a wheel setup appropriate for 6.25-16 tires. On a collector car, replacement wheels, long-term storage, or earlier modifications can change what is actually on the vehicle, so a quick wheel and clearance check is worthwhile before choosing new tires.
What size rim does a 1940 Chrysler Windsor 25 use?
The 1940 Chrysler Windsor 25 uses a 16-inch rim with its 6.25-16 tire size. In this sizing format, the final number identifies the wheel diameter, so the tire is built for a 16-inch wheel rather than a different rim size.
Rim diameter is the first measurement to verify before replacement, especially on an older car that may have seen wheel changes during its life. The buyer should also inspect wheel width and general wheel condition, since a correct diameter alone does not guarantee that every wheel on the car is suitable for service with a new bias-ply tire.
Does the 1940 Chrysler Windsor 25 6 Cyl. use the same tire size?
Yes. The 1940 Chrysler Windsor 25 6 Cyl. uses the same 6.25-16 bias-ply tire size as the model covered on this page. There is no separate primary tire size to sort through for that sub-model.
That keeps selection fairly simple, but it still helps to confirm what is physically on the car before purchasing replacement tires. A prewar vehicle can have mixed wheels, older replacements, or prior modifications, so matching the tire size to the actual 16-inch wheel setup and checking clearance and condition are still important steps.
Choosing the Right Tire
What should I consider when choosing a 6.25-16 tire for a 1940 Chrysler Windsor 25?
Start with the correct primary fitment: 6.25-16 in a bias-ply construction. For a 1940 Chrysler Windsor 25, that keeps the tire choice aligned with the car's period sizing system and the type of construction commonly associated with a prewar passenger car.
From there, the real decision is how the car will be used and presented. A restoration-oriented car may call for a more traditional look, while a regularly driven car still needs careful attention to wheel condition, tire age, and general roadworthiness. Choosing the right tire means balancing appearance, intended use, and the actual wheel setup on the vehicle.
How do I choose between the available 6.25-16 tires for a 1940 Chrysler Windsor 25?
The right choice begins with staying in the correct 6.25-16 size and matching the tire to the 16-inch wheel setup on the car. On a prewar Chrysler, that usually means focusing first on proper fitment and construction rather than chasing modern sizing substitutions.
After fitment is confirmed, compare the tires by the character you want the car to have. Some buyers prioritize a more restoration-minded presentation, while others focus on getting the car back into dependable touring service. Wheel condition, intended driving speed, storage habits, and how original the car remains all help narrow the best option for that specific Windsor 25.
What rim-fitment details should I compare when choosing 1940 Chrysler Windsor 25 tires?
The most important rim-fitment detail is the 16-inch wheel diameter required by the 6.25-16 tire size. On an older vehicle like the 1940 Chrysler Windsor 25, the wheel itself also deserves attention, since age, repairs, or prior replacement parts can affect whether it is ready for new tires.
A buyer should inspect the wheel for straightness, corrosion, cracks, and general service condition before mounting fresh tires. It also helps to confirm that all four wheels match in size and type. Those checks matter because a correct tire size alone does not overcome problems caused by damaged wheels or mismatched hardware.
Restoration & Appearance
Which tire should I choose for a period-style 1940 Chrysler Windsor 25?
For a period-style 1940 Chrysler Windsor 25, the natural starting point is the correct 6.25-16 bias-ply size. That keeps the car within the sizing format and construction style associated with a prewar Chrysler and helps preserve the visual character expected from a sedan of this era.
The best choice depends on how exact the restoration needs to be. Some owners want a broadly authentic road presentation, while others are matching a more detailed historical standard. When originality matters at a deeper level, it is worth checking marque references, restoration photos, and vehicle-specific documentation before settling on the final tire appearance.
Does correct tire fitment matter for a 1940 Chrysler Windsor 25 restoration?
Yes, correct tire fitment matters a great deal on a 1940 Chrysler Windsor 25 restoration. Tire size and construction strongly affect the car's stance, visual balance, and the way the finished vehicle reads as a prewar Chrysler rather than a car wearing a later, out-of-period substitute.
Beyond appearance, proper fitment also supports sensible wheel compatibility and road-use preparation. A restoration can look finished and still hide old wheels, aged tires, or mismatched components that need attention. Staying with the proper 6.25-16 format gives the project a sound baseline before the finer points of appearance and drivability are considered.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1940 Chrysler Windsor 25?
Yes. Modifications can change tire fitment on a 1940 Chrysler Windsor 25 even when the intended replacement size is still 6.25-16. Replacement wheels, altered ride height, brake conversions, or body and suspension work can all influence the space available around the tire.
That is why the actual car should be checked before mounting new tires. Steering clearance, fender clearance, wheel diameter, and wheel condition all matter on a vehicle of this age. A Windsor 25 that has remained stock may be straightforward, but a modified example deserves a more careful measurement and inspection routine.
What should I inspect before driving a 1940 Chrysler Windsor 25 on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and the new tires themselves for proper mounting and inflation. It is also smart to check for any signs of rubbing at the front suspension, steering components, inner fenders, and rear wheel openings on the 1940 Chrysler Windsor 25.
A prewar car should also be looked over as a complete system rather than as tires alone. Brake function, wheel bearings, alignment condition, and suspension wear can all affect how the car behaves once fresh tires are installed. A careful first drive at moderate speed helps catch any vibration, pull, or clearance issue early.
How should 6.25-16 tires on a collector 1940 Chrysler Windsor 25 be maintained?
Maintain 6.25-16 tires on a collector 1940 Chrysler Windsor 25 with regular pressure checks, visual inspections, and sensible storage habits. Even a lightly driven car can develop problems from age, prolonged sitting, sunlight, moisture, or exposure to ozone sources such as electric motors and certain shop equipment.
Inspect the tread and sidewalls for cracking, bulges, cuts, uneven wear, or slow air loss before driving. It also helps to move the car periodically and keep it on a clean, dry surface. Collector vehicles often age out tires before they wear them out, so condition matters just as much as remaining tread depth.
