1932 Lincoln 12 Tires

The 1932 Lincoln 12 uses a 750-18 tire size. This is a bias-ply fitment, and the covered Base sub-model uses that same primary size rather than a separate alternate size.

That simplifies the first step of tire selection, but it does not make every 750-18 automatically the same for every car. It is still important to confirm the actual wheel dimensions on the vehicle, especially on a prewar car that may have had wheel changes over the years, then choose the tire style and product type that match the car’s appearance goals and road use.

The primary tire fitment for the 1932 Lincoln 12 is built around an 18-inch rim. The 750-18 size uses that 18-inch diameter, which is the key wheel measurement to verify before selecting a replacement tire.

Rim diameter is only part of the fitment picture on a vintage Lincoln. Some 750-18 products are built for a 4-inch rim, while others call for wider 6.00 to 6.50-inch rims, so the wheel setup needs to match the specific tire being considered rather than the size code alone.

In the 750-18 size format, 7.50 refers to the tire’s nominal section width in inches and 18 refers to the rim diameter in inches. It is a vintage numeric bias-ply sizing system commonly associated with prewar vehicles such as the 1932 Lincoln 12.

Understanding that format helps separate period tire sizing from later metric and radial conventions. It also helps when comparing products in the same size, because the car may still need a decision between a traditional passenger-car presentation, such as whitewall or blackwall, and a heavier-duty truck-style design with different rim-width and load characteristics.

Start with the correct primary size, which is 750-18, then compare construction style, rim compatibility, sidewall appearance, and the type of tire each product represents. For this Lincoln, the available choices include traditional Firestone Balloon options as well as heavier-duty blackwall truck-oriented designs.

A restoration-minded car may call for a more formal whitewall or blackwall passenger-car look, while a vehicle with a different wheel setup may need closer attention to rim width. Load specification can matter too, but it should be viewed alongside the actual wheel and vehicle setup rather than used by itself as the deciding factor.

The 1932 Lincoln 12 has 750-18 tire choices with several sidewall treatments, including blackwall, wide whitewall, and double-whitewall. Those options give the car very different visual character even when the primary tire size remains the same.

For many owners, sidewall style is the biggest appearance decision once the size is confirmed. A whitewall treatment can suit a formal prewar luxury presentation, while a blackwall can create a more restrained look, but the final choice should still be checked against the tire’s intended rim width and the way the car is being restored or driven.

Tires for the 1932 Lincoln 12 in 750-18 are available from Firestone, Deka, and STA. Firestone covers the traditional Balloon-style passenger-car presentation, while Deka and STA also bring blackwall options with more truck-oriented character.

Brand choice should be considered alongside the product’s sidewall style, tire series, rim-width requirement, and intended use. A buyer choosing strictly by brand can miss important differences between a formal whitewall passenger-car tire and a heavier-duty blackwall design that may suit a different wheel setup or a different look.

A period-style 1932 Lincoln 12 usually starts with the correct 750-18 bias-ply size, because the size and construction shape the car’s stance and prewar presentation. Within that size, Firestone Balloon options are especially relevant for buyers looking for a traditional passenger-car appearance.

The next step is deciding how formal or restrained the finished car should look. Wide whitewall, double-whitewall, and blackwall treatments can all change the visual impression, so buyers focused on exact historical authenticity should compare the tire choice against marque references, period photography, and the specific restoration standard of the car.

On a restored 1932 Lincoln 12, bias-ply construction plays a major role in the vehicle’s period presentation because it matches the vintage size format and overall look associated with this era. In this application, the primary fitment remains 750-18 bias-ply rather than a modern radial format.

That matters visually as much as mechanically, since construction influences the way the tire looks on the wheel and under the fender openings. Even within the same basic size, sidewall treatment and tire series can shift the car toward a more formal luxury appearance or a plainer blackwall presentation, so the tire should support the restoration goal.

Yes, modifications can affect tire fitment on a 1932 Lincoln 12 even when the primary size remains 750-18. Changes to wheels, rim width, suspension height, brake components, or body clearances can all alter whether a particular tire is appropriate for the car’s current setup.

That is especially important here because some 750-18 tires are intended for a 4-inch rim while others call for 6.00 to 6.50-inch rims. A Lincoln that has been changed over time should be measured rather than assumed original, and steering clearance and fender clearance should be checked before the car returns to regular road use.

Before driving a 1932 Lincoln 12 on new tires, inspect the wheels for correct diameter and width, check that the tires are seated properly, and confirm there is no interference at the fenders, steering components, or suspension. Tire pressure should also be set appropriately for the tire and wheel combination in use.

A prewar car benefits from a broader road-readiness inspection as well. Wheel hardware, brake condition, steering play, and suspension wear can all influence how the car behaves once new tires are installed, so the first drive should be cautious and followed by another check for clearance, air retention, and any unusual wear pattern.

750-18 tires on a collector 1932 Lincoln 12 should be inspected regularly for cracking, cuts, bulges, uneven wear, and air loss, even if the car is driven only occasionally. Long periods of storage can age a tire quietly, so appearance alone is not enough to judge roadworthiness.

Storage conditions matter on a vintage Lincoln. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires, and maintaining correct inflation during storage can reduce stress on the casing. A car that has been sitting should have its tires and wheels checked carefully before any extended drive.
