The 1937 Cadillac 90 Series sits at the upper end of Cadillac’s pre-war luxury lineup, a large and dignified automobile from an era when ride quality, road presence, and formal styling mattered as much as mechanical sophistication. That character makes tire choice especially important, because the tire has a major effect on stance, appearance, and driving feel. The 1937 Cadillac 90 Series uses a 750-16 bias-ply tire on a 16-inch rim, giving this page a straightforward fitment story centered on one primary size. Within that size, the real choice becomes blackwall versus wide whitewall presentation and selecting a tire series that suits restoration goals and intended road use.
Which Tire Size Is Right for The 1937 Cadillac 90 Series
The 1937 Cadillac 90 Series uses one primary tire size: 750-16. It is a bias-ply fitment on a 16-inch rim, and the same size applies to the covered V16 sub-model as well. That means the main decision is not which size fits, but which 750-16 tire best matches the car’s appearance, intended use, and wheel setup.
A 750-16 tire uses the vintage numeric bias-ply sizing system, where 7.50 refers to the nominal section width in inches and 16 refers to the wheel diameter. On the 1937 Cadillac 90 Series, this is the primary bias-ply fitment and it supports the tall, substantial visual character expected of a large pre-war Cadillac. Available choices in this size include Firestone, Lester, BFGoodrich, and STA, with both blackwall and wide whitewall styles plus several tire series. Choosing among them comes down to whether the car is being restored for traditional presentation, regular touring, or a more specialized heavy-duty application.
Fitment is straightforward across the covered 1937 Cadillac 90 Series sub-model range. The key value in checking the sub-model is simply confirming that the vehicle remains on its expected wheel and tire setup before choosing among the available 750-16 bias-ply options.

1937 Cadillac 90 Series V16
The 1937 Cadillac 90 Series V16 uses the same 750-16 bias-ply tire size as the model core. That keeps selection focused on presentation and use, such as choosing a blackwall or wide whitewall tire and confirming the wheel remains a 16-inch setup.
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.

Tire Size & Fitment
What tire size fits a 1937 Cadillac 90 Series?
The 1937 Cadillac 90 Series uses a 750-16 tire size. This is a vintage numeric bias-ply fitment, and it mounts on a 16-inch rim. The covered V16 sub-model uses the same primary size, so the basic fitment question is unusually straightforward for this Cadillac.
Once the size is confirmed, the next step is choosing the type of 750-16 tire that suits the car. A restoration-minded owner may focus on sidewall presentation, while a driver may compare tire series and intended use. It is also worth checking that the car still has its expected 16-inch wheels and has not been altered with different rims over the years.
What size rim does a 1937 Cadillac 90 Series use?
The primary tire fitment for the 1937 Cadillac 90 Series uses a 16-inch rim. In the available 750-16 products, the common rim-width range is 5.00 to 6.00 inches, which is useful when comparing wheel compatibility for replacement tires in this size.
Rim diameter is the first item to confirm on a collector car that may have seen wheel changes during its life. A 750-16 tire is built for a 16-inch wheel, so matching only the section width is not enough. Checking both wheel diameter and width helps narrow the right product and reduces the chance of clearance or mounting issues.
What does 750-16 mean on a 1937 Cadillac 90 Series?
On a 1937 Cadillac 90 Series, 750-16 is a vintage numeric bias-ply size. The 7.50 refers to the nominal section width in inches, while the 16 refers to the rim diameter in inches. It is an older sizing format that predates modern metric radial designations.
Understanding that format helps when comparing available 750-16 tires, because the size itself stays the same while the tire series, sidewall treatment, and intended use can vary quite a bit. It also helps explain why modern-looking metric sizes are not part of the primary fitment story for this Cadillac, even though buyers may be more familiar with them today.
Choosing the Right Tire
What should I consider when choosing a 750-16 tire for a 1937 Cadillac 90 Series?
Start with the correct size and construction: the 1937 Cadillac 90 Series uses a 750-16 bias-ply tire. From there, compare the tire’s intended character, sidewall style, and wheel compatibility. In this size, choices range from traditional passenger-car style tires to heavier-duty military and truck-style designs.
A wide whitewall often suits a formal pre-war luxury presentation, while a blackwall gives a plainer or more utility-oriented look. It also helps to compare rim-width guidance, weight, and load figures where they are stated. Matching the tire to the car’s appearance and intended driving use is more helpful than simply picking the first tire in the correct size.
What sidewall styles are available for 1937 Cadillac 90 Series tires?
The available 750-16 tires for the 1937 Cadillac 90 Series come in both blackwall and wide whitewall styles. That gives owners a meaningful appearance choice within the correct size, especially on a pre-war Cadillac where tire sidewalls contribute heavily to the overall visual balance of the car.
Wide whitewalls usually appeal to restoration-oriented buyers who want a more formal period-style presentation, while blackwalls create a more restrained or utilitarian look. Sidewall style should still be chosen alongside the tire series and intended use, because two tires can share the same appearance category while being aimed at very different driving or load conditions.
What brands offer tires for the 1937 Cadillac 90 Series?
The 750-16 size for the 1937 Cadillac 90 Series is available from Firestone, Lester, BFGoodrich, and STA. Those brands cover several bias-ply series, including traditional passenger-car styles as well as truck and military-style variations within the same base size.
Brand alone is only part of the decision. It is better to compare the combination of sidewall style, tire series, rim-width compatibility, and intended use before choosing. A whitewall Firestone or BFGoodrich may suit a formal restoration theme, while certain STA and Firestone military-style products are aimed at more specialized heavy-duty or utility applications.
Restoration & Appearance
Which tire should I choose for a period-style 1937 Cadillac 90 Series?
A period-style 1937 Cadillac 90 Series begins with the correct 750-16 bias-ply size. Within that fitment, traditional passenger-car bias-ply tires are the natural starting point for a restoration-oriented look, especially when the goal is to preserve the tall stance and visual character associated with a large pre-war Cadillac.
The best final choice depends on how closely the car is being restored and how it will be used. Wide whitewall options often suit the era visually, but exact originality can vary by vehicle history and restoration standard. When that level of detail matters, marque references, historic photos, and vehicle-specific documentation remain the strongest guides.
How does tire construction affect the appearance of a restored 1937 Cadillac 90 Series?
Tire construction affects both the look and attitude of a restored 1937 Cadillac 90 Series. A 750-16 bias-ply tire supports the traditional profile and visual presence most owners expect on a pre-war luxury car, especially when paired with a sidewall treatment that suits the restoration’s overall theme.
Appearance is not only about whitewall versus blackwall. The tire series itself can influence whether the car reads as formal passenger luxury or more utility-oriented. Since this Cadillac’s primary fitment story centers on bias-ply tires, staying within the correct size and selecting a presentation that matches the body and wheel setup usually matters more than chasing novelty.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1937 Cadillac 90 Series?
Yes, modifications can affect tire fitment on a 1937 Cadillac 90 Series even when the tire size remains 750-16. Wheel changes, altered rim widths, suspension work, brake conversions, or body and fender adjustments can all change how a tire sits and whether it has adequate clearance during steering and suspension movement.
A collector car that has been updated over time should be checked carefully before replacement tires are chosen. Confirming wheel diameter and width is the starting point, then inspect for space around the sidewall, tread, and steering components. A tire in the correct nominal size still needs to suit the actual wheel and chassis configuration on the car today.
What should I inspect before driving a 1937 Cadillac 90 Series on new tires?
Before driving a 1937 Cadillac 90 Series on new tires, inspect the wheels for the correct 16-inch size and sound condition, then check the tires for proper inflation and secure mounting. It also makes sense to look over steering and suspension components, since worn parts can affect how a large pre-war car tracks and responds.
After installation, watch for rubbing at full steering lock and under normal suspension movement. A short, careful road test can reveal vibration, pull, or clearance issues early. Since collector cars often sit for long periods, it is also wise to inspect brake function and general chassis condition so the new tires are not being asked to compensate for unrelated mechanical problems.
How should 750-16 tires on a collector 1937 Cadillac 90 Series be maintained?
Maintaining 750-16 tires on a collector 1937 Cadillac 90 Series starts with regular pressure checks and visual inspections for cracking, cuts, bulges, and uneven wear. Because many pre-war cars are driven occasionally rather than daily, age and storage conditions often matter just as much as tread depth.
Clean, dry storage away from prolonged sunlight, heat, and ozone sources helps preserve the tire casing and sidewalls. Periodic movement of the car can also help reduce long-term flat spotting during storage. Before longer drives, inspect for air loss and confirm the tires still match the wheel setup, especially if the Cadillac has changed hands or been off the road for an extended period.
