The 1930 La Salle 340 came from a period when American luxury and near-luxury cars still carried tall, narrow tires that shaped both stance and ride character. As a companion marque to Cadillac, La Salle blended upscale design with the formal road manners buyers expected at the start of the 1930s. For this exact model, the tire decision centers on two 19-inch bias-ply fitments, 31X6.20 and 650-19, both closely tied to the car’s era and appearance. Available choices include traditional blackwall and wide whitewall presentations across several vintage-style series. The right selection depends on preserving the car’s period look while confirming the wheel setup actually on the vehicle.
Which Tire Size Is Right for The 1930 La Salle 340
The 1930 La Salle 340 uses two primary tire sizes, and both are bias-ply fitments on 19-inch wheels. Since the covered sub-model shares both sizes, the key step is confirming which size is mounted on the car now and making sure the wheel dimensions match before choosing between blackwall and wide whitewall tire options.
The 31X6.20 size uses an older format that names the tire by approximate overall diameter first and nominal section width second. On the 1930 La Salle 340, it represents a tall bias-ply tire suited to the upright proportions and period road feel expected from an early 1930s automobile. Tire selection in this fitment should stay focused on authentic vintage-style construction and the actual wheel setup on the car. It is a size worth evaluating carefully when preserving the vehicle’s original visual balance and confirming that the mounted wheel is the correct 19-inch application.
The 650-19 size is a numeric bias-ply designation in which 6.50 refers to nominal section width and 19 identifies the wheel diameter in inches. For the 1930 La Salle 340, this is a traditional vintage fitment with meaningful product choice, including Firestone, Lester, and Excelsior offerings in blackwall and wide whitewall styles, plus series such as Firestone Classic Bias Ply, Firestone Balloon, Lester Classic Bias Ply, and Comp H. This size gives restoration-minded owners more visible appearance options, so it is especially important to match the tire to the wheel width and the car’s intended presentation.
Sub-model fitment is straightforward here because the covered 1930 La Salle 340 sub-model uses the same pair of bias-ply tire sizes. The main task is not sorting through trim differences, but verifying which size and wheel combination is actually on the car before replacement.

Tire Size & Fitment
What tire size fits a 1930 La Salle 340?
The 1930 La Salle 340 uses two primary bias-ply tire sizes: 31X6.20 and 650-19. Both fitments belong to the vehicle’s vintage-era tire sizing landscape, and both are tied to a 19-inch wheel application for this model.
The practical next step is to confirm which size is actually mounted on the car before ordering replacements. Older collector cars are often changed over time, so checking the existing tire size, the wheel diameter, and the wheel width matters more than assuming every La Salle 340 still carries the same setup it had decades ago.
What size rim does a 1930 La Salle 340 use?
The 1930 La Salle 340 uses a 19-inch rim diameter with its primary tire fitments. That 19-inch wheel size is the common point shared by the model’s bias-ply tire applications, including 650-19 and the alternate 31X6.20 fitment.
Rim diameter should be verified before selecting tires because a vintage car may no longer have its original wheels. Checking only the tire sidewall is not enough if the car has been restored, modified, or fitted with different wheels at some point, so measuring the wheel and confirming its width can prevent an expensive mismatch.
Does the 1930 La Salle 340 8 Cyl. use the same tire size?
Yes. The 1930 La Salle 340 8 Cyl. uses the same two primary tire sizes associated with this model: 31X6.20 and 650-19, both in bias-ply construction. There is no separate sub-model-only tire size to sort through here.
That makes the buying decision more about the car’s present wheel and tire setup than about trim differences. A quick inspection of the mounted tires, wheel diameter, and overall restoration direction will usually tell you whether the car should stay with the size already installed or move to the other original-style fitment used on this model.
Choosing the Right Tire
What should I consider when choosing a tire for a 1930 La Salle 340?
Start with the correct primary size on the car, then confirm the 19-inch wheel dimensions before narrowing the choices. Since the 1930 La Salle 340 uses vintage bias-ply fitments, the decision usually comes down to preserving the proper early-1930s look, selecting the sidewall treatment you want, and matching the tire to the wheel setup.
For 650-19, compare series, sidewall appearance, and wheel-width compatibility rather than choosing by looks alone. A wide whitewall can transform the car’s presentation, while blackwall options create a more restrained look, and the best choice depends on how the La Salle is restored, displayed, and driven.
What sidewall styles are available for 1930 La Salle 340 tires?
The 650-19 fitment for the 1930 La Salle 340 is available in both blackwall and wide whitewall styles. Those sidewall choices create noticeably different visual character, even when the tire size and basic bias-ply construction remain the same.
Blackwall tires tend to suit a more understated presentation, while wide whitewalls bring a stronger period-style visual statement to an early 1930s car. The right choice depends on the look you want from the finished vehicle, but it should still be matched with the correct size, wheel fitment, and intended road use.
What brands offer tires for the 1930 La Salle 340?
In 650-19, the 1930 La Salle 340 has available tire choices from Firestone, Lester, and Excelsior. Those brands appear across several vintage-style offerings, including Firestone Classic Bias Ply, Firestone Balloon, Lester Classic Bias Ply, and Comp H.
Brand alone should not be the only deciding factor on a collector car like this. It makes more sense to compare the exact size, sidewall style, tire series, and wheel-width suitability so the tire matches both the La Salle’s physical setup and the visual direction of the restoration.
Restoration & Appearance
Which tire should I choose for a period-style 1930 La Salle 340?
A period-style 1930 La Salle 340 should stay with one of its correct bias-ply primary sizes, either 31X6.20 or 650-19, depending on the wheel and tire setup on the car. That keeps the vehicle aligned with the tall, formal tire profile associated with early 1930s American automobiles.
For a restoration-oriented result, the next choice is usually sidewall presentation and series rather than a different construction type. If exact originality matters beyond general period style, compare your car against marque references, surviving photos, and restoration records before settling on a specific sidewall treatment.
How does tire construction affect the appearance of a restored 1930 La Salle 340?
Bias-ply construction plays a major role in the restored look of a 1930 La Salle 340 because it preserves the tall, vintage tire character that suits the car’s era. On this model, the primary fitments are bias-ply, so construction choice is closely tied to maintaining the right overall stance and presentation.
Appearance is not only about sidewall color or whitewall width. The tire’s profile, proportion, and how it fills the wheel opening all influence whether the La Salle looks visually settled, so construction should be considered alongside the actual size on the car and the finish level of the restoration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 La Salle 340?
Yes. Modifications can affect tire fitment on a 1930 La Salle 340, especially if the car has different wheels, altered suspension height, brake conversions, or body changes that were made long after it left the factory era. Even a correct vintage tire size can become problematic if the surrounding setup has changed.
A careful check of wheel diameter, wheel width, steering clearance, and fender clearance is worthwhile before replacing old tires. On a collector car, it is also smart to confirm that front and rear wheel setups match, since decades of repairs or restorations sometimes leave the car with a mixed arrangement.
What should I inspect before driving a 1930 La Salle 340 on new tires?
Before driving a 1930 La Salle 340 on new tires, inspect the wheels for condition and proper size, make sure the tires are seated correctly, and confirm that inflation is appropriate for the tire and vehicle setup. A quick visual check for rubbing at full steering lock is also important.
Road readiness on an early collector car goes beyond the tire itself. Look over the suspension, steering components, valve stems, and any signs of uneven clearance so the new tires are not being asked to work around worn hardware or a mismatched wheel, which can affect both wear and drivability.
How should 1930 La Salle 340 tires be maintained?
Tires on a 1930 La Salle 340 should be maintained with regular pressure checks, routine inspections for cracking, cuts, bulges, and air loss, and periodic review of tread and sidewall condition. Collector cars that sit for long periods deserve especially close attention because age and storage conditions can affect tire health.
Storage habits matter almost as much as mileage on a vintage car. Keeping the La Salle away from prolonged sunlight, moisture, and ozone sources can help preserve the tires, and rotating or at least moving the car occasionally can reduce flat spotting and reveal clearance or suspension issues before a longer drive.
