The 1929 La Salle 8 Cyl. came from an era when American luxury cars balanced advanced styling with long-wheelbase road manners and substantial presence. As a companion marque to Cadillac, La Salle appealed to buyers who wanted premium engineering with its own distinct identity. Tire selection for the 1929 La Salle 8 Cyl. centers on two 19-inch bias-ply fitments, 31X6.20 and 650-19, both tied to the car’s period driving character and visual stance. Within 650-19, there are meaningful choices in blackwall and wide whitewall presentation across Firestone, Lester, and Excelsior offerings. The right decision usually comes down to preserving a restoration-oriented look, confirming wheel setup, and matching the tire’s style to how the car will be shown or driven.
Which Tire Size Is Right for The 1929 La Salle 8 Cyl.
The 1929 La Salle 8 Cyl. uses two primary tire sizes, and both are bias-ply fitments on 19-inch wheels. Since the Base sub-model is associated with both sizes, the first step is confirming which tire size is actually on the car now and whether the wheels match that setup. From there, the decision shifts to period-style appearance, brand preference, and sidewall treatment.
A 31X6.20 tire uses an older diameter-by-section format, where 31 refers to the tire’s approximate overall diameter in inches and 6.20 refers to its nominal section width. It is a bias-ply fitment that suits the pre-war driving feel and visual proportions expected on a 1929 La Salle 8 Cyl. This format is especially relevant to owners trying to stay close to an early tire-sizing convention rather than moving into later numeric bias-ply sizing. It is best evaluated by confirming the wheel setup already on the car and comparing the installed tire’s dimensions and clearance before selecting a replacement.
A 650-19 tire uses a numeric bias-ply size format, with 6.50 representing nominal section width in inches and 19 indicating the rim diameter. On the 1929 La Salle 8 Cyl., it provides a traditional bias-ply construction and is available in several period-style presentations, including blackwall and wide whitewall versions. Firestone, Lester, and Excelsior offerings appear in this size, along with series such as Firestone Classic Bias Ply, Firestone Balloon, Lester Classic Bias Ply, and Comp H. This size gives the buyer the broadest visible choice when appearance, brand preference, and wheel-width compatibility all matter.
Sub-model fitment is straightforward here because the covered Base configuration is associated with both primary tire sizes. Checking the exact tire size already fitted to the car still matters, since replacement selection depends on matching the existing wheel and preserving the intended period look.

1929 La Salle 8 Cyl. Base
The 1929 La Salle 8 Cyl. Base is associated with both 31X6.20 and 650-19 bias-ply tires. That makes the real decision less about trim level and more about confirming which wheel-and-tire setup the car carries now before choosing a blackwall or wide whitewall replacement.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1929 La Salle 8 Cyl. Tires for Sale
Available 650-19 choices span Firestone, Lester, and Excelsior, with blackwall and wide whitewall sidewalls across several classic bias-ply series. Product differences are most meaningful in appearance, series character, and wheel-width compatibility on 19-inch rims.
Owners of a 1929 La Salle 8 Cyl. usually need to sort out the correct 19-inch tire size first, then compare bias-ply options by appearance, brand, and wheel compatibility. The questions below focus on fitment, period-style selection, and road-use checks for a collector-era car.
Tire Size & Fitment
What tire size fits a 1929 La Salle 8 Cyl.?
The 1929 La Salle 8 Cyl. uses two primary bias-ply tire sizes: 31X6.20 and 650-19. Both sizes are associated with this vehicle, and the Base sub-model is tied to both fitments rather than to one exclusive size.
That means the right replacement starts with confirming what is actually mounted on the car now. Check the sidewall size marking, verify the wheel diameter, and compare the overall wheel-and-tire setup before ordering, especially on a restoration or a car that may have had wheels changed over the years.
What size rim does a 1929 La Salle 8 Cyl. use?
The 1929 La Salle 8 Cyl. uses a 19-inch rim with its primary tire fitments. The numeric bias-ply size 650-19 states that rim diameter directly, and the available products in that size are built for 19-inch wheels.
Rim diameter is only one part of fitment, so it is still worth checking the actual wheel on the car before replacing tires. On collector vehicles, wheels may have been changed, restored, or mixed over time, and wheel width can also matter when comparing among available 650-19 tire options.
What does 31X6.20 mean on a 1929 La Salle 8 Cyl.?
31X6.20 is an antique diameter-by-section tire size. In that format, 31 refers to the tire’s approximate overall diameter in inches, while 6.20 refers to its nominal section width rather than to the wheel diameter.
That older sizing style can look unfamiliar beside a numeric size such as 650-19, so it is important not to assume the two markings describe the tire in the same way. The safest next step is to inspect the wheels and the size currently fitted, then compare the replacement against the vehicle’s existing setup and clearance.
Choosing the Right Tire
What should I consider when choosing a 650-19 tire for a 1929 La Salle 8 Cyl.?
Start with the basics: 650-19 must match the car’s wheel diameter, and it should suit the wheel width and intended use of the vehicle. Beyond size, available choices vary by brand, tire series, and sidewall style, including blackwall and wide whitewall presentations.
A restoration-oriented car may call for one appearance, while a touring car may lead you toward a different series or wheel-width specification. It also helps to compare product details such as rim-width range, weight, and any stated load figure so the tire selection matches the actual wheel and driving plan.
What sidewall styles are available for 1929 La Salle 8 Cyl. tires?
The available 650-19 tire options for the 1929 La Salle 8 Cyl. include blackwall and wide whitewall sidewall styles. Those two looks create very different visual results even when the overall tire size and bias-ply construction remain the same.
Blackwall tires usually suit a more restrained period presentation, while wide whitewalls create a stronger visual accent on a large late-1920s luxury car. The right choice depends on the look you want, the car’s trim and paint treatment, and whether the goal is touring use, show presentation, or a balanced restoration-minded appearance.
What brands offer tires for the 1929 La Salle 8 Cyl.?
In 650-19, the 1929 La Salle 8 Cyl. has tire options from Firestone, Lester, and Excelsior. Those choices appear across several classic bias-ply series, including Firestone Classic Bias Ply, Firestone Balloon, Lester Classic Bias Ply, and Comp H.
Brand alone should not be the only deciding factor. Compare the sidewall style you want, the tire series presentation, and any wheel-width details that apply to your car, especially if the La Salle has been driven, restored, or re-wheeled in a way that differs from its earlier setup.
Restoration & Appearance
Which tire should I choose for a period-style 1929 La Salle 8 Cyl.?
A period-style choice for a 1929 La Salle 8 Cyl. begins with the correct primary size already fitted to the car, then narrows to a bias-ply tire that matches the vehicle’s intended visual presentation. In 650-19, that can mean choosing between blackwall and wide whitewall versions across several vintage-style series.
For many restorations, the appearance of the sidewall matters just as much as the size. Buyers seeking exact historical accuracy should compare the tire choice against marque-club guidance, period photos, or restoration records, while those aiming for a broadly era-appropriate look can focus on size, profile, and sidewall style.
Does correct tire fitment matter for a 1929 La Salle 8 Cyl. restoration?
Correct tire fitment matters a great deal on a 1929 La Salle 8 Cyl. because tire size and sidewall style strongly affect stance, proportions, and the overall visual balance of the car. A large luxury car from this period can look noticeably different when the tire format or sidewall treatment is off.
Fitment also affects practical details such as wheel compatibility and body clearance, so restoration choices should not be made by appearance alone. Matching the replacement to the actual wheels on the car helps preserve both the look and the usability of the finished vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 La Salle 8 Cyl.?
Yes. A 1929 La Salle 8 Cyl. may no longer have its earlier wheel setup, and any change to wheel size, wheel width, suspension height, or body clearance can affect how a replacement tire fits. That matters even when the tire carries one of the vehicle’s primary sizes.
Older cars are often restored in stages, so it is wise to inspect the current wheel-and-tire arrangement before replacing anything. Checking wheel dimensions, steering clearance, and fender space helps prevent choosing a tire that matches the sidewall marking but does not suit the car’s present configuration.
What should I inspect before driving a 1929 La Salle 8 Cyl. on new tires?
Before road use, inspect wheel condition, valve stems, mounting quality, inflation, and visible tire seating on the rim. It is also smart to confirm that the tires clear the fenders and steering components through the full range of motion, especially on a long-wheelbase collector car.
A short, careful test drive can reveal vibration, rubbing, or handling issues before the car is taken farther from home. Recheck inflation and look over the sidewalls and tread after the first drive so any mounting or clearance concern is caught early rather than after extended use.
How should 650-19 tires on a collector 1929 La Salle 8 Cyl. be maintained?
Collector-car tires such as 650-19 bias-ply tires should be inspected regularly for air loss, tread wear, cracking, bulges, and cuts, even when the car is driven only occasionally. Long periods of storage can age a tire quietly, so appearance alone should not be the only standard.
Proper pressure, clean storage conditions, and protection from prolonged sunlight, moisture, and ozone sources all help preserve tire condition. It also helps to look over the tires before and after each outing, since low annual mileage often means problems develop gradually rather than during constant road use.
