The 1936 Cadillac 70 Series came from an era when Cadillac balanced formal luxury with the engineering confidence that defined premium American cars before the war. Whether equipped as a V8 or V12, this model calls for a substantial tire that suits its scale, weight, and road manners. The primary fitment is a 750-16 bias-ply tire on a 16-inch rim, which keeps the vehicle in the period sizing and construction family it was designed around. Available choices include traditional blackwall and wide whitewall presentations, along with several bias-ply series aimed at different appearance and use preferences. The real decision is choosing the right 750-16 for restoration style, intended driving, and wheel compatibility.
Which Tire Size Is Right for The 1936 Cadillac 70 Series
The 1936 Cadillac 70 Series uses one primary tire size: 750-16. It is a bias-ply fitment on a 16-inch rim, and that same size is used across the V8 and V12 sub-models covered here. Since the size itself is straightforward, the real choice becomes which 750-16 tire best matches the car's appearance, intended road use, and preference for blackwall, wide whitewall, or more utility-oriented tread styles.
A 750-16 is a vintage numeric bias-ply size in which the 7.50 designates the tire's nominal section width in inches and the 16 identifies the wheel diameter. On a 1936 Cadillac 70 Series, that means a period-appropriate bias-ply construction intended for a 16-inch rim rather than a modern metric radial format. Within this size, choices include Firestone, Lester, BFGoodrich, and STA products, with blackwall and wide whitewall sidewall treatments as well as several tire series. Selecting among them depends less on size and more on whether the car is being finished for traditional touring appearance, formal restoration presentation, or more utility-focused service.
Fitment is straightforward across the covered 1936 Cadillac 70 Series sub-models. Both the V8 and V12 use the same 750-16 bias-ply tire size, so the main task is choosing the right tire style and series rather than sorting through different primary fitments.

1936 Cadillac 70 Series V12
The 1936 Cadillac 70 Series V12 uses the same 750-16 bias-ply fitment as the rest of the covered line. That keeps tire selection centered on appearance and intended use, such as choosing between blackwall and wide whitewall presentations while still confirming the wheel setup on the individual car.
The 1936 Cadillac 70 Series V8 also uses the 750-16 bias-ply size on a 16-inch rim. For this sub-model, the decision is less about fitment variation and more about selecting a tire series and sidewall treatment that suits restoration goals and the way the car will be driven.
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 1936 Cadillac 70 Series?
The 1936 Cadillac 70 Series uses a 750-16 tire size. This is a numeric bias-ply fitment on a 16-inch rim, and it applies across the covered V8 and V12 versions of the model.
That makes the size question fairly simple, but the car may still need a closer look before replacement. A long-restored or modified Cadillac can have different wheels than expected, so it is wise to confirm the wheel diameter and width on the car and then choose the 750-16 tire that best matches the vehicle's appearance and intended use.
What size rim does a 1936 Cadillac 70 Series use?
The primary tire fitment for the 1936 Cadillac 70 Series is built around a 16-inch rim. Products in 750-16 are also associated with a 5.00 to 6.00 inch rim-width range where that specification is stated.
Rim diameter is the first detail to confirm because a 16-inch tire must be mounted on a 16-inch wheel. On a collector car, it also helps to verify actual wheel width, especially if the car has had replacement wheels fitted over the years, since proper width support affects tire shape, mounting, and clearance.
Do all 1936 Cadillac 70 Series sub-models use the same tire size?
Yes. Both the 1936 Cadillac 70 Series V8 and 1936 Cadillac 70 Series V12 use the same 750-16 bias-ply tire size. There is no primary size split between those covered sub-models.
That consistency makes sub-model identification less critical than it is on some later vehicles with trim-dependent fitments. Even so, the best next step is still to inspect the car's current wheels and tire markings, because older collector vehicles sometimes carry non-original wheel setups or service replacements that can change what is mounted today.
Choosing the Right Tire
What should I consider when choosing a 750-16 tire for a 1936 Cadillac 70 Series?
Start with the correct 750-16 size and a bias-ply construction that suits the car's original-era setup. From there, compare sidewall style, tire series, rim-width compatibility, and whether the tire is aimed at classic passenger-car presentation or more utility-oriented service.
A formal pre-war Cadillac often looks very different on a blackwall than it does on a wide whitewall, so appearance can matter as much as specification. It also helps to compare load figures where given and to think honestly about use, since a car driven occasionally to shows may call for a different presentation than one expected to handle more regular road mileage.
What sidewall styles are available for 1936 Cadillac 70 Series tires?
The available 750-16 choices include both blackwall and wide whitewall sidewall styles. That gives the 1936 Cadillac 70 Series owner a meaningful appearance choice without changing the primary tire size.
Blackwall tires usually create a more restrained, service-oriented look, while wide whitewalls bring a more formal and restoration-focused presentation that many pre-war luxury cars wear well. Sidewall style should be chosen with the car's overall finish in mind, including wheel color, trim level, and whether the goal is road use with period flavor or a stronger show-oriented visual statement.
What brands offer tires for the 1936 Cadillac 70 Series?
The 750-16 size for the 1936 Cadillac 70 Series is available from Firestone, Lester, BFGoodrich, and STA. Those brands appear across several bias-ply series and sidewall treatments, including both traditional passenger-car styles and more utility-focused designs.
Brand alone is not the whole decision on a car like this. It is more useful to compare the individual tire's series, sidewall presentation, rim-width specification, and stated load figure when available, then match those details to the Cadillac's intended role, whether that means formal restoration appearance, occasional local driving, or broader road use.
Restoration & Appearance
Which tire should I choose for a period-style 1936 Cadillac 70 Series?
A period-style 1936 Cadillac 70 Series starts with the correct 750-16 bias-ply size. From there, the most restoration-oriented choices are usually the classic passenger-car bias-ply lines rather than the more utility-focused military or transport-style offerings in the same size.
The final choice depends on how the car is being presented. A wide whitewall can give the Cadillac a more formal pre-war luxury look, while a blackwall delivers a plainer, more restrained appearance. Exact originality can vary by body style, market, and surviving documentation, so serious restoration work benefits from marque-specific references before settling on a sidewall treatment.
Does correct tire fitment matter for a 1936 Cadillac 70 Series restoration?
Yes, correct tire fitment matters both visually and mechanically on a 1936 Cadillac 70 Series. The 750-16 size establishes the proper vintage scale for the car, and staying with a bias-ply construction preserves the traditional profile and stance associated with this era.
Using the right size is also important because large pre-war cars can look noticeably off when the tire proportions are not in keeping with the wheel and body. Even on a driver-quality restoration, it helps to confirm wheel dimensions, compare sidewall style carefully, and avoid assuming that any 16-inch tire will present or sit correctly on the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1936 Cadillac 70 Series?
Yes. Even though the primary size is 750-16, modifications can change what actually works on a 1936 Cadillac 70 Series. Replacement wheels, different wheel widths, brake updates, suspension work, or body changes can all affect tire mounting space and operating clearance.
Older Cadillacs often pass through decades of repairs and alterations, so it is smart to inspect the car rather than rely only on what should be there. Check wheel diameter, actual rim width, clearance at the fender and steering components, and whether the suspension sits at its intended height before mounting a new set of tires.
What should I inspect before driving a 1936 Cadillac 70 Series on new tires?
Inspect the wheels, valve stems, mounting surfaces, and overall tire clearance before road use. The 1936 Cadillac 70 Series should also be checked for proper inflation, secure wheel attachment, and any interference during full steering travel and normal suspension movement.
A careful pre-drive inspection matters especially on collector cars that may sit for long periods. Look over the rest of the chassis as well, including brakes, steering play, shocks, and wheel bearings, because a fresh set of tires cannot compensate for worn mechanical components. A short, low-speed test drive is a sensible way to confirm that everything feels settled.
How should 750-16 tires on a collector 1936 Cadillac 70 Series be maintained?
750-16 tires on a collector 1936 Cadillac 70 Series should be kept properly inflated, inspected regularly for cracking, cuts, bulges, uneven wear, and air loss, and stored away from prolonged sunlight, moisture, and ozone sources whenever possible.
Collector cars often age tires by time rather than mileage, so visual condition matters as much as tread depth. It also helps to move the car periodically, keep the wheels clean, and look for changes after storage or long idle periods. Any tire that shows visible deterioration or repeated pressure loss deserves closer inspection before the Cadillac returns to the road.
