1940 Cadillac 60 Series Tires

The 1940 Cadillac 60 Series uses a 700-16 tire size. This is a numeric bias-ply fitment paired with a 16-inch rim, and the covered 60 Series Special V8 uses that same size as well.

That makes the first step fairly simple: confirm that the car still has its proper 16-inch wheels and has not been changed to a different wheel setup over the years. After size is verified, the decision shifts to sidewall style, tire series, and whether the car is being prepared for restoration-focused presentation or regular collector-car driving.

The 1940 Cadillac 60 Series uses a 16-inch rim with its 700-16 tire fitment. Several available 700-16 products also specify a rim-width range of 4.50 to 5.50 inches, which is useful when checking wheel compatibility.

Rim diameter should always be confirmed directly on the wheel before ordering tires, especially on a prewar car that may have seen replacement wheels during its lifetime. Rim width and wheel condition matter too, since a tire in the correct diameter still needs to suit the actual wheel and leave proper clearance at the fenders and steering components.

Yes. The 1940 Cadillac 60 Series Special V8 uses the same 700-16 bias-ply tire size as the core 1940 Cadillac 60 Series fitment. There is no separate primary size change shown for that covered sub-model.

That consistency makes tire shopping easier, but it does not eliminate the need to inspect the car itself. A Special V8 that has aftermarket wheels, altered suspension height, or wheels with a different width than expected should still be measured carefully so the selected 700-16 tire matches the actual wheel and vehicle setup.

Start with the correct 700-16 size and a bias-ply construction that suits the 1940 Cadillac 60 Series. Then compare sidewall style, tire series, brand, rim-width compatibility where stated, and whether the tire is aimed at passenger-car use or a more specialized military or truck-style application.

A wide whitewall usually supports a more formal prewar luxury presentation, while a blackwall creates a more restrained look. It also helps to compare load figures and the pressure attached to them when those specifications are given, especially if the car will be driven regularly rather than displayed or used only for short local outings.

The available 700-16 choices for a 1940 Cadillac 60 Series include both blackwall and wide whitewall sidewall styles. That gives owners a meaningful appearance choice without changing the primary tire size.

Sidewall style has a major effect on how a prewar Cadillac presents itself, especially on a large, formal car with substantial body mass and prominent fenders. Buyers pursuing a restoration-oriented look often compare whitewall width and overall visual balance, while drivers more focused on understated road use may prefer the simpler look of a blackwall tire.

The 700-16 size for the 1940 Cadillac 60 Series is available from Lester, Avon, BFGoodrich, Firestone, Tornel, and STA. Those choices span classic passenger-style bias-ply offerings as well as some military and truck-oriented designs in the same nominal size.

Brand alone should not decide the purchase. It is better to compare the tire’s sidewall treatment, intended character, rim-width suitability where stated, and whether the tread design matches how the Cadillac will actually be used. A restoration-focused sedan often calls for a very different presentation than a vehicle being outfitted for utility-style or specialized display purposes.

A period-style 1940 Cadillac 60 Series starts with the correct 700-16 bias-ply size on a 16-inch rim. From there, the most relevant choices are usually among classic passenger-style bias-ply series and the visual difference between blackwall and wide whitewall presentations.

For many prewar Cadillac restorations, appearance matters as much as fitment, because the tire contributes heavily to the car’s stance and overall character. Exact originality can vary by body, delivery history, and restoration goal, so owners seeking the most historically precise look should compare tire appearance details against marque references and other vehicle-specific documentation.

Yes, correct tire fitment matters a great deal on a 1940 Cadillac 60 Series restoration. Using the proper 700-16 size helps preserve the car’s visual proportions, wheel-to-fender relationship, and the traditional bias-ply profile expected on a prewar luxury Cadillac.

A tire that is merely close in size can change the look of the car even before it affects road behavior. Restorers should pay attention to sidewall treatment, tread style, and wheel compatibility, because those details strongly influence whether the finished Cadillac reads as authentically prewar in character rather than simply being fitted with a generically old-looking tire.

Yes. Even though the 1940 Cadillac 60 Series uses a 700-16 tire, modifications can change whether a particular tire choice suits the car. Wheel replacements, altered rim widths, suspension changes, brake conversions, or body work can all influence actual fitment.

A prewar Cadillac may also have accumulated decades of repairs that are not obvious at first glance. Measuring the current wheel diameter and width, checking front steering clearance, and inspecting rear fender and suspension space can prevent problems before mounting new tires. Those checks are especially important when the car is no longer on its original wheel and chassis setup.

Before road use, inspect the wheels for condition, verify the tire beads seat properly, and confirm that inflation matches the tire being used. It is also wise to check that the new 700-16 tires clear the fenders, steering components, and suspension through the full range of motion.

A car from 1940 deserves a broader safety check than tires alone. Look for loose or worn steering parts, aged suspension bushings, brake issues, uneven ride height, and any signs of rubbing after a short test drive. Collector cars that sit for long periods should also be checked for slow air loss and any changes in sidewall condition before regular use.

700-16 tires on a collector 1940 Cadillac 60 Series should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and stored away from prolonged sunlight, heat, moisture, and ozone sources when the car is parked for extended periods.

Low annual mileage does not eliminate tire aging, especially on a large prewar car that may spend much of its time in storage. Periodic pressure checks, moving the car occasionally to avoid long static loading, and rechecking the tires before tours or event travel will help preserve both the appearance and roadworthiness of the tire set.
