1946 Lincoln Zephyr Tires

The 1946 Lincoln Zephyr uses a 700-15 tire size. This is a numeric bias-ply fitment on a 15-inch rim, and the covered 12 Cyl. sub-model uses that same primary size rather than a separate fitment.

That makes size identification fairly simple, but the next step is still important. A Zephyr that has been fitted with different wheels over the years should have its actual wheel diameter and width confirmed before a tire is chosen. Once the wheel setup checks out, the main comparison points become sidewall style, tire series, and whether the car is being kept close to a restoration-oriented presentation or used in a more utility-minded role.

The 1946 Lincoln Zephyr uses a 15-inch rim with its 700-15 tire fitment. Several applicable 700-15 products are built around a 15-inch rim diameter, which matches the size designation used on the vehicle.

Rim diameter is only part of the fitment picture, especially on an older collector car. Some 700-15 tires are paired with a 5.00 to 5.50 inch rim width range, so wheel width deserves a closer look as well. A Zephyr that still has its original-style wheels may be straightforward, but any wheel swap, restoration change, or long-ago repair work should be checked before installing a new set.

Yes. The 1946 Lincoln Zephyr 12 Cyl. uses the same 700-15 bias-ply tire size as the model core. There is no separate primary tire size for that covered sub-model, so the fitment remains consistent.

That consistency simplifies the search, because the tire decision shifts away from sorting out sub-model size differences. A buyer can spend more time comparing appearance details such as blackwall versus wide whitewall, along with the character of the available tire series. Even so, it is still wise to confirm the actual wheel setup on the car, since older luxury cars are sometimes restored or modified with wheels that differ from the original pattern.

Start with the basics: the 1946 Lincoln Zephyr uses a 700-15 bias-ply tire on a 15-inch rim. After confirming size and wheel compatibility, the most meaningful differences are sidewall style, tire series, intended application, and whether the car is being restored for a traditional presentation or prepared for more specialized use.

A wide whitewall can give the Zephyr a more formal period-style look, while a blackwall changes the visual character considerably. Some 700-15 options also lean toward military, truck, or transport-style service rather than a classic passenger presentation. Comparing load figures where stated, rim-width guidance where available, and overall appearance helps narrow the choice without treating every tire in the size as the same.

The available 700-15 tires for a 1946 Lincoln Zephyr include blackwall and wide whitewall sidewall styles. Those two treatments create very different visual results even though they share the same basic size and bias-ply construction format.

Sidewall choice matters on a postwar luxury car because the tire has a major effect on the car's stance and finished appearance. A wide whitewall usually suits a more formal restoration-minded presentation, while a blackwall gives a plainer and sometimes more utility-focused look. Choosing between them is less about fitment than about how closely the finished Zephyr should reflect the period style the owner wants to emphasize.

Tires for the 1946 Lincoln Zephyr are available in 700-15 from Firestone, BFGoodrich, and STA. Those brands appear across several bias-ply product lines, including classic passenger-style offerings and more utility-oriented series in the same nominal size.

Brand alone should not be the only decision point. It helps to compare the sidewall presentation, the tire series, the stated rim-width range when included, and any load figures tied to a specific pressure. A Zephyr being restored for show and occasional touring may call for a different visual and functional approach than one being equipped with a more rugged, truck-influenced tire series.

A period-style 1946 Lincoln Zephyr usually starts with the correct primary size and construction, which here means a 700-15 bias-ply tire. That preserves the sizing format and visual character associated with a car from the immediate postwar era, rather than shifting the appearance toward a modern tire profile.

From there, appearance details become the key distinction. A wide whitewall often complements the formal look many restorers want from a Zephyr, while a blackwall can create a more restrained presentation. If exact originality matters beyond general period style, the safest next step is to compare the tire choice against marque-club guidance, historical photos, or other vehicle-specific restoration references before making a final decision.

Tire construction has a visible effect on a restored 1946 Lincoln Zephyr because the car was designed around a bias-ply tire profile and stance. Using the 700-15 bias-ply format keeps the sidewall shape and overall visual impression closer to what enthusiasts usually expect on a car from this era.

Appearance is not just about sidewall color. The combination of construction, sidewall height, and tread character all influences how substantial or formal the Zephyr looks once it is sitting on the ground. For a restoration-minded owner, keeping the right size and a traditional bias-ply presentation often matters as much as paint or trim details, especially on a full-bodied Lincoln where the tire is a prominent part of the finished profile.

Yes. Even though the standard fitment is 700-15 on a 15-inch rim, modifications can change what works on a 1946 Lincoln Zephyr. Wheel swaps, altered rim widths, suspension changes, brake conversions, or body and fender work can all affect clearance and how a tire sits on the car.

A collector car that has passed through several owners may have changes that are not obvious at first glance. Measuring the actual wheel diameter and width, checking steering travel, and inspecting clearance at the fenders and suspension points can prevent unpleasant surprises. That matters even when staying with the original tire size, because an incorrect wheel or altered chassis setup can change the fitment outcome significantly.

Before driving a 1946 Lincoln Zephyr on new tires, inspect the wheels for correct diameter and condition, verify proper mounting, and make sure the tires are inflated appropriately for the chosen product. It is also smart to check valve stems, wheel hardware, and any tube or tubeless requirements tied to the specific tire and wheel combination.

The car itself deserves attention too. Steering components, suspension wear, brake condition, and wheel-bearing health can all affect how a fresh set of tires performs on the road. A short, careful test drive helps confirm that there is no rubbing, pulling, vibration, or unusual air loss. On a low-use postwar car, mechanical condition is often just as important as the tire itself.

700-15 tires on a collector 1946 Lincoln Zephyr should be checked regularly for air pressure, sidewall cracking, tread wear, bulges, cuts, and signs of flat spotting from long storage. Bias-ply collector tires often spend more time parked than driven, so condition and age deserve close attention even when tread depth still looks good.

Storage habits matter as much as mileage. Keeping the Zephyr away from prolonged heat, direct sunlight, moisture, and ozone sources helps preserve the tires, and moving the car periodically can reduce the effects of sitting in one place. A quick inspection before every outing is a good routine on an older luxury car, especially before a longer drive where heat and sustained speed place more demand on the tires.
