1929 La Salle Tire Fitment Guide

Two tire sizes fit 1929 La Salle vehicles covered here: 31X6.20 and 650-19. Both apply to the 1929 La Salle 8 Cyl., and both are bias-ply sizes mounted on 19-inch wheels. Among the currently available 650-19 products, listed rim-width guidance appears at 3.25 to 3.50 inches on some Firestone Balloon applications, which is the main wheel-dimension reference available within this fitment range.

That means a 1929 La Salle owner does not need to sort through multiple model-specific wheel diameters first, but does need to verify which of the two original-style sizes is actually correct for the car. The best starting point is the tire already on the car, followed by a check of the wheel itself and any restoration records. If the car is being judged or restored to a particular standard, a marque specialist or club can help confirm which of the two period sizes best matches the intended presentation.

A 31X6.20 tire on a 1929 La Salle uses an older diameter-by-section format. The first number, 31, refers to the tire's overall outside diameter in inches, while 6.20 refers to its nominal section width. This is not a modern metric or alphanumeric code, and it does not place the wheel diameter in the same obvious way a later 650-19 or 205/75R15 size would.

That older format matters because it places the tire squarely in the visual and engineering language of the late 1920s. Owners looking for a proper early appearance often pay close attention to these antique-format markings, since the code itself reflects the era's sizing conventions. Before choosing a replacement, compare the sidewall marking on the existing tire and verify that the wheel and overall stance of the car match what you are trying to preserve.

A 650-19 tire on a 1929 La Salle is a numeric bias-ply size. The 6.50 portion represents the nominal section width in inches, and the 19 indicates the wheel diameter in inches. It is a later, more familiar vintage sizing convention than 31X6.20, but it is still an era-correct bias-ply format rather than a modern radial or metric designation.

That makes 650-19 easier for many collectors to recognize, and it also has the broader product selection here, including Firestone and Lester offerings in both blackwall and wide-whitewall styles. If your La Salle already carries 650-19 markings, staying with that size usually keeps the buying process simpler because the available choices are clearer. Even so, wheel width still deserves attention, especially if the car has been restored, re-wheeled, or stored for many years before returning to service.

Both 31X6.20 and 650-19 are bias-ply choices for the 1929 La Salle 8 Cyl., and both fit a 19-inch wheel diameter. The practical difference is not bias-ply versus radial, but which original-style size best matches your car's existing fitment and restoration direction. A car that already wears one of these sizes should generally stay with that same size unless there is a strong historical reason to correct it.

Owners usually make this decision by starting with authenticity and visual proportion rather than by chasing a different driving character, since both options remain period-style bias-ply constructions. If the goal is a tightly researched restoration, compare the sidewall markings on the current tires, old photos, and period service references for your specific car. If the goal is casual touring in a vintage-correct style, choose the size that matches the wheel and stance you want to maintain.

1929 La Salle tires in 650-19 are available in both Blackwall and Wide Whitewall sidewall styles. Firestone offers blackwall and wide-whitewall choices in that size, and Lester also offers a wide-whitewall version. Those sidewall differences do not change the fundamental bias-ply construction, but they do change the visual character of the finished car in a noticeable way.

A blackwall usually suits a more restrained, workmanlike, or lightly accessorized appearance, while a wide whitewall creates a more formal luxury look that many owners associate with premium late-1920s American cars. For a judged restoration, the right answer depends on how the particular car was delivered and how strict the event standards are. If the car is more of a driver or a stylistic restoration, sidewall choice becomes part of the overall presentation rather than a fitment issue.

Firestone and Lester both make tires for 1929 La Salle vehicles within the available 650-19 fitment. Firestone appears in both its Classic Bias Ply and Balloon lines, while Lester offers a classic bias-ply wide-whitewall option. All of those listed products stay within the period-correct bias-ply construction family used by a car of this age.

Brand choice on a 1929 La Salle usually comes down to the look you want and the exact product characteristics available in the chosen size, such as sidewall treatment and any published wheel-width or load information. Firestone carries strong period recognition for many American collector car owners, while Lester is often chosen for its traditional whitewall presentation on luxury-era cars. Once the size is settled, comparing sidewall style is often the next most meaningful step.

Rim-width guidance appears on some 1929 La Salle 650-19 products at 3.25 to 3.50 inches. All listed 1929 La Salle tire sizes mount on 19-inch wheels, but the only published width range within the available products is tied to certain 650-19 Firestone Balloon applications. That makes 650-19 the clearest place to start when you want a printed wheel-width reference before selecting a tire.

Wheel width matters because a correct 19-inch diameter alone does not automatically confirm that every tire in the size family will sit or wear as intended. On an older car, wheels may have been changed, repaired, or mixed over time, especially during long restorations. Measuring the actual wheel before choosing a tire is the safest way to avoid a mismatch between a correct-looking size code and the wheel currently on the car.

The original-style 1929 La Salle wheels can generally be considered compatible with both listed tire sizes from a diameter standpoint, because both 31X6.20 and 650-19 fit 19-inch rims. That shared rim diameter is the most important point of overlap between the two choices. It means the question is usually not whether the wheel diameter is correct, but whether the wheel width and the specific tire's fitment guidance also line up.

That distinction is important on a car from 1929 because many surviving cars have lived through decades of wheel swaps, restoration work, and storage. A 19-inch wheel may still need closer checking before moving from one period-style size to the other. If your wheels are original or believed to be original, inspect their dimensions carefully and compare them with the published guidance on the tire you are considering rather than assuming every 19-inch vintage tire fits the same way.

A 1929 La Salle should be stored away from direct sunlight, electric motors, battery chargers, welders, furnaces, and other ozone-producing sources that accelerate sidewall aging. Keep the floor area dry, maintain proper inflation, and move the car periodically so the tire carcass is not loaded in one spot for months at a time. Because 1929 La Salle fitments here are bias-ply, they are especially prone to temporary flat-spotting after long static storage.

Many owners reduce strain during extended storage by rolling the car a short distance every few weeks or by using properly placed stands as part of a broader storage plan. The key is to protect the tires from environment and inactivity rather than just from tread wear. Collector cars often age their tires long before they wear them out, so good storage habits can preserve ride quality, appearance, and confidence when the car returns to the road.

Tires on a 1929 La Salle usually age out before they wear out, especially on collector cars that see limited annual mileage. A practical rule is to evaluate them closely once they reach the five- to seven-year range and to treat around ten years as a serious replacement consideration regardless of tread depth. The date code on the tire helps establish age, which matters more than mileage on a car that spends long periods parked.

Age-based replacement is especially important on pre-war and late-1920s style vehicles because owners often focus on visible tread and overlook hardened rubber, sidewall cracking, or degraded inner components. A handsome bias-ply tire can still be too old for comfortable road use. If the age is uncertain, or the car has recently come out of long-term storage, a fresh inspection by someone familiar with vintage tires is wiser than judging condition by appearance alone.

Tires on a 1929 La Salle should be inspected before every drive, and they deserve an extra-close check before tours, club events, or any longer outing at sustained road speed. Look for sidewall cracking, cuts, bulges, irregular tread wear, and signs of pressure loss. Because this is a late-1920s collector car, the spare tire and its valve condition also deserve inspection rather than being treated as decorative backup equipment.

Frequent inspection matters because older cars often sit long enough for problems to develop quietly between drives. A tire that looked acceptable at the last event may show aging or air loss after a season in storage. Building a short pre-drive routine around pressure, sidewall condition, and the spare helps turn tire care into a habit, and it reduces the chance that a preventable issue interrupts a drive in a car that may already demand more attention than a modern vehicle.

A 1929 La Salle 8 Cyl. would have been fitted in the bias-ply era, and the two listed period-style sizes for this year and model are 31X6.20 and 650-19. Both reflect vintage sizing systems used before modern radial and metric conventions became standard. The original factory-supplied brand should not be assumed from current reproduction availability, since present-day offerings and historic assembly-line sourcing are not always the same thing.

For a restoration, the most useful takeaway is that keeping the car in a proper bias-ply size and an era-appropriate sidewall style matters more than chasing a brand assumption. If your goal is exact historical accuracy, compare surviving car evidence, factory literature, and trusted La Salle or Cadillac-La Salle club guidance. Market, coachwork, delivery date, and later service history can all influence what is considered correct on an individual car.

Correct tire fitment absolutely matters when showing a 1929 La Salle, especially at events that judge authenticity rather than just overall condition. Size, construction type, and sidewall presentation all affect whether the car looks appropriate for its year. On a late-1920s luxury car, an obviously modern construction or a sidewall treatment that clashes with the period can stand out even to casual observers, and it may matter more to judges than owners expect.

That does not mean every event applies the same standards, but it does mean tire choice should be part of the restoration plan rather than an afterthought. A well-finished La Salle can lose some of its period credibility if the tires look visually out of step with the rest of the car. Before a judged event, review that organization's standards and compare them with marque-club advice so the tire size and sidewall style support the level of authenticity you are aiming for.

For the 1929 La Salle in 650-19, Firestone Balloon and Lester Wide Whitewall differ in both presentation and published specifications. Firestone Balloon appears in blackwall and 3.50-inch whitewall versions, includes listed rim-width guidance of 3.25 to 3.50 inches on some products, and one whitewall version carries a published maximum load of 1430 pounds at 36 psi. The Lester offering in this fitment is a wide-whitewall bias-ply tire with a heavier listed weight than the blackwall Firestone alternatives.

That means the decision is not simply brand name versus brand name. Firestone gives a little more published setup detail within this size, while Lester presents another traditional luxury-era whitewall option for owners shaping the final look of the car. If you are narrowing the field between them, compare sidewall appearance first, then use the available wheel-width and load information to make sure the selected tire aligns with the car's wheels and intended use.

1929 La Salle tires can be suitable for normal road use when they are fresh, correctly fitted, properly inflated, and matched to a mechanically sound car, but they remain vintage-style bias-ply constructions. No speed ratings are shown on the listed 1929 La Salle products here, so owners should approach modern highway use with the expectations appropriate to a late-1920s automobile. On a car of this era, braking, steering response, suspension condition, and overall chassis health are often just as important as the tire itself.

In practical terms, highway safety for a 1929 La Salle starts with respecting the car's age and design rather than assuming reproduction tires make it behave like a newer vehicle. A well-sorted La Salle on healthy bias-ply tires can be enjoyable on secondary roads and moderate-speed touring, but sustained high-speed travel deserves more caution and more preparation. If the car is newly restored or recently awakened from storage, begin with shorter drives and build confidence gradually.

Inflation pressure for 1929 La Salle tires should be guided first by the original vehicle recommendation for the specific car and second by the tire maker's published limits for the exact product you choose. Within the listed 650-19 offerings, one Firestone Balloon whitewall shows a maximum load of 1430 pounds at 36 psi, but that figure is tied to that specific tire and should not be transferred automatically to every 1929 La Salle tire. Pressure choice is never one-size-fits-all across vintage fitments.

That is why the owner's manual, restoration literature, and the selected tire's own specifications should all be considered together. On an older luxury car, ride quality and steering feel can change noticeably with inflation, and overinflating to a tire's maximum figure is not the same thing as using the car's intended running pressure. Start from the correct vehicle guidance for your chosen size, then fine-tune only within the tire maker's permitted range.

Before a longer drive in a 1929 La Salle, inspect each tire for cracks, cuts, bulges, uneven wear, and stable inflation, then give the spare the same level of attention. Check valve condition, look for any bead or sidewall irregularity, and make sure the wheels themselves are clean and sound where the tire seats. A touring check on a car of this age should also include brakes, steering, wheel bearings, fluid levels, and the general readiness of the cooling and electrical systems.

The reason to be thorough is that a 1929 car asks for a more complete pre-drive ritual than a modern one, and tire condition is only one part of roadworthiness. Even a good-looking collector tire can hide age or storage-related issues until the car is driven at length. Owners who treat the tires, spare, and chassis as one system usually have more relaxed and dependable outings, especially on club tours where roadside support may be limited.
