1933 Lincoln Tire Fitment Guide

1933 Lincoln vehicles use two different tire sizes, and the correct one depends on the model. The 1933 Lincoln 125 HP uses 700-18, while the 1933 Lincoln V12 uses 750-18. Both sizes are bias-ply fitments built for 18-inch wheels. For 700-18, available products fit 3.75- to 4.00-inch rims. For 750-18, available passenger-car products use a 4-inch rim, while one heavier-duty truck-style option is built for a much wider 6.00- to 6.50-inch rim.

That means year and make alone are not enough to choose correctly for a 1933 Lincoln. Start by confirming whether your car is a 125 HP or a V12, then compare the wheel on the car to the rim-width requirement of the specific tire you are considering. On restored prewar cars, wheel swaps and replacement rims are common enough that it is worth checking the actual wheel before finalizing your selection.

On a 1933 Lincoln, 700-18 is a numeric bias-ply tire size. The 700 portion is the old-style nominal section-width code, and the 18 identifies the wheel diameter in inches. This size belongs to the 1933 Lincoln 125 HP and is offered in traditional prewar bias-ply construction with blackwall, double-whitewall, and wide whitewall sidewall styles.

Modern buyers sometimes mistake the first number for tread width measured the same way as a modern metric tire, but numeric bias-ply sizing follows an earlier convention. The practical takeaway is that 700-18 is not interchangeable with the larger 750-18 simply because both fit 18-inch wheels. If your 1933 Lincoln is a 125 HP, stay with 700-18 unless you are working with a knowledgeable marque specialist on a nonstandard setup.

No, 1933 Lincoln models do not all use the same tire size. The 125 HP uses 700-18, while the V12 uses 750-18. Both are period-correct bias-ply 18-inch fitments, but they are tied to different models within the lineup rather than shared across the entire year and make.

That distinction matters because a buyer looking only at 1933 Lincoln tires could easily end up comparing products that belong to a different model family. Once the model is confirmed, the next choices become much simpler: sidewall appearance, the exact rim-width match for the product, and whether the tire is being selected for a formal restoration look or for a more utilitarian application within the available offerings.

1933 Lincoln tires are available in several authentic-looking sidewall treatments. In 700-18, Firestone offers blackwall, double-whitewall, and wide whitewall versions. In 750-18, Firestone also offers blackwall, double-whitewall, and wide whitewall choices, while Deka offers a blackwall truck-style tire. That gives owners room to tailor the appearance while staying within proper prewar bias-ply sizing.

Sidewall style has a major effect on how a 1933 Lincoln presents, especially on large formal bodies where the tire is visually prominent. Blackwalls generally suit a more restrained or utilitarian look, while whitewall treatments create a richer luxury-car appearance often favored on restored classics from the period. If authenticity matters for a particular body style, coachbuilder, or show class, compare your choice against period photos and marque-club guidance before settling on the final look.

Firestone and Deka both offer tires for 1933 Lincoln applications, but they do not cover the lineup in the same way. The 700-18 size for the 1933 Lincoln 125 HP is offered in Firestone passenger-car patterns. The 750-18 size for the 1933 Lincoln V12 includes Firestone passenger-car tires as well as a Deka truck-style blackwall option with a different rim-width requirement and heavier-duty load profile.

For most prewar Lincoln restorations, Firestone's passenger-car offerings align closely with the look collectors expect on luxury cars of the era. The Deka option broadens the 750-18 choice set, but it should be treated as a specialized alternative rather than a default replacement for every V12. Brand selection on a 1933 Lincoln is really a combination of model, wheel compatibility, and the visual character you want the finished car to carry.

For the 1933 Lincoln 125 HP in 700-18, both Firestone Balloon and Firestone Classic Bias Ply options are available. They share the same 18-inch rim diameter, the same 3.75- to 4.00-inch rim-width range, and the same listed load figure of 1520 pounds at 36 psi. The main visible difference within the Firestone Balloon line is sidewall presentation, with blackwall, double-whitewall, and wide whitewall versions available, while the listed Firestone Classic Bias Ply option appears as a blackwall.

That means the decision is less about a dramatic fitment change and more about the exact look and product character you want on the car. If you are trying to capture a distinctly prewar luxury appearance, the whitewall variations in the Balloon family will likely be the first place to look. If you prefer a more understated blackwall presentation, comparing the two Firestone series within the same size can help you refine the final restoration style.

Rim width depends on both the size and the specific tire chosen for a 1933 Lincoln. In 700-18, available tires are built for 3.75- to 4.00-inch rims. In 750-18, Firestone passenger-car products use a 4-inch rim, while the Deka truck-style tire requires a much wider 6.00- to 6.50-inch rim. All of these tires fit 18-inch wheel diameters, but rim width is not the same across every product.

That is why the wheel on the car should be measured or verified before making a final decision, especially on a 1933 Lincoln V12 where one available tire falls outside the narrow passenger-car rim range. A reproduction or replacement wheel can look correct at a glance and still differ in width. Matching the tire to the actual rim helps preserve proper profile, bead seating, and the visual stance expected on a prewar luxury car.

Both tire sizes used on 1933 Lincoln models mount on 18-inch wheels, so they share the same wheel diameter. That said, the sizes are assigned to different models, and the available tires do not all call for the same rim width. The 700-18 fits narrower 3.75- to 4.00-inch rims, while 750-18 products range from a 4-inch passenger-car rim to a much wider truck-style fitment depending on the tire chosen.

In practical terms, wheel diameter alone does not make every original 1933 Lincoln wheel suitable for every available tire. A 125 HP wheel setup should stay with 700-18 fitments, and a V12 owner should confirm not just the 18-inch diameter but also the actual rim width before selecting among 750-18 options. That is especially important if the car has had wheel changes during an older restoration or long-term ownership.

A stored 1933 Lincoln should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment that can accelerate sidewall aging. Bias-ply tires also tend to flat-spot more readily during long periods of inactivity than later radial designs, especially on heavy prewar luxury cars. Clean floors, stable temperatures, and proper inflation all help protect the tire casing during storage.

If the car will sit for months, move it periodically or place it on stands in a way that protects both the tires and suspension according to your restoration practice. Avoid parking on damp earth or surfaces that hold moisture against the rubber. When the car comes out of storage, inspect each tire carefully before driving, because a 1933 Lincoln's age and weight make tire condition especially important even when tread wear appears minimal.

On a 1933 Lincoln, tire life should be judged more by age and condition than by mileage. Collector cars often travel relatively few miles, so tread depth alone can give a false sense of security. A sensible rule is to evaluate tires closely once they reach roughly five to seven years of age and to treat around ten years as a serious replacement consideration, depending on storage history, visible condition, and how the car is used.

The most useful check is the overall health of the casing: look for sidewall cracking, deformation, hardening, impact damage, and any persistent air-loss issue. A low-mileage prewar car can still need new tires if the rubber has aged out. Keep a record of installation dates and inspect date markings where applicable so the tire's service age is always part of your maintenance planning for the 1933 Lincoln.

Tires on a 1933 Lincoln should be inspected before every drive and again before any longer outing. Check inflation, visible cracking, tread and shoulder condition, cuts, bulges, and any sign that the car has been sitting on a soft or underinflated casing. Because these are bias-ply applications on a prewar vehicle, even a small issue can have a noticeable effect on ride quality, steering feel, and confidence at speed.

A more thorough inspection at regular service intervals is also worthwhile, especially after winter storage or long stationary periods. Pay close attention to valve stems and the spare as well as the four road tires, since the spare is often forgotten until it is urgently needed. On a 1933 Lincoln, a careful walk-around before departure is part of responsible operation, not just a restoration habit.

The 1933 Lincoln 125 HP uses 700-18 tires, and the period-correct construction for a car of this era is bias-ply. That matches the available fitment for the model today. In the early 1930s, luxury American cars such as Lincoln were built around bias-ply tire technology, so the key authenticity markers are the correct size, the proper general construction type, and an era-appropriate sidewall treatment rather than a modern radial substitute.

If you are restoring a particular body style or preparing for judged events, use the 700-18 size as your foundation and then refine the choice by comparing blackwall, double-whitewall, or wide whitewall presentation against period photographs and club guidance. Original-equipment brand usage could vary by market and circumstance, so the safest path for a highly exact restoration is to pair the correct size and construction with advice from Lincoln marque specialists.

Correct tire fitment absolutely matters when a 1933 Lincoln is judged for authenticity. On a prewar luxury car, judges and knowledgeable enthusiasts notice whether the size matches the model, whether the tire uses the right general construction type for the era, and whether the sidewall style suits the way the car would have appeared in period. A modern-looking substitute or the wrong model-specific size can stand out immediately on a car with large visible wheel openings.

For a 125 HP, that means staying with 700-18; for a V12, it means staying with 750-18 unless there is a very specific historical reason to do otherwise. After that, the most sensitive authenticity choice often becomes sidewall appearance. Event standards differ, so if your 1933 Lincoln is being prepared for concours judging rather than general display, compare your tire choice against the rules and consult Lincoln-focused clubs before finalizing the setup.

The 1933 Lincoln V12 uses 750-18 tires, and the historically appropriate construction type for the model is bias-ply. That aligns with the available offerings in this size. Because the V12 sat at the more prestigious end of the 1933 Lincoln range, owners today often pay close attention not only to the size itself but also to the sidewall presentation, since the tire contributes heavily to the stance and visual richness of a formal prewar luxury car.

A faithful V12 restoration should begin with the 750-18 size and then narrow the choice according to wheel compatibility and appearance. Passenger-car Firestone options are the closest match to the period luxury-car impression most restorers seek, while the Deka truck-style tire is more specialized and should be evaluated carefully before using it on a show-oriented Lincoln. For body- and coachwork-specific authenticity, marque experts remain the best final reference.

1933 Lincoln tires can be suitable for normal road use when they are the correct size for the model, properly mounted on the right wheel, in sound condition, and inflated appropriately for the application. The available 700-18 and 750-18 choices here are all bias-ply tires, which deliver an authentic prewar driving character rather than the feel of a modern radial. On a 1933 luxury car, the broader mechanical condition of the vehicle often matters at least as much as the tire itself once speeds rise.

Highway confidence in a 1933 Lincoln depends on more than tread alone. Steering play, brake condition, wheel bearings, alignment, and suspension health should all be part of the conversation before taking a prewar car on faster roads. A freshly restored Lincoln on correct bias-ply tires can be very enjoyable, but it should still be driven with an understanding of its era, weight, and handling characteristics rather than modern-car expectations.

Available load-and-pressure figures differ by tire on 1933 Lincoln applications, so pressure should never be transferred casually from one product or size to another. In 700-18, listed tires carry 1520 pounds at 36 psi. In 750-18, Firestone passenger-car tires are listed at 1930 pounds at 40 psi, while the Deka truck-style 750-18 is listed at 2540 pounds at 65 psi. Those figures are tire ratings, not blanket vehicle settings.

Use the original owner or service literature for the car as the starting point for factory-style running pressure, then compare that with the tire manufacturer's published load and pressure range for the exact tire you choose. Because 1933 Lincoln tires span different model applications and even different product types within 750-18, the safest practice is to match the inflation decision to the exact tire, wheel, and vehicle setup rather than copying a number from a different version.

Before a longer outing in a 1933 Lincoln, inspect every tire for cracks, cuts, bulges, irregular wear, and any sign of impact damage or age-related separation. Confirm inflation when the tires are cold, and do not forget the spare. Since these are bias-ply prewar fitments, also pay attention to how long the car has been sitting, because flat-spotting or hidden casing issues may not become obvious until the car begins rolling.

The tire check should be part of a broader pre-drive review that includes brakes, wheel bearings, steering, suspension, and fluid levels. On an older luxury car, a small weakness can become much more noticeable on a sustained drive than on a short local trip. If your 1933 Lincoln has older tires with attractive tread but questionable age, the wiser decision may be to address that first before asking the car to cover real distance.
