La Salle 8 Cyl. Tires
La Salle 8 Cyl. was Cadillac’s companion marque entry into the American luxury field, and across the late 1920s into the mid-1930s it reflected a period when styling, wheel sizes, and tire design were changing quickly. Early La Salle 8 Cyl. cars sit in the transition from oversized balloon-era dimensions to later, lower-diameter wheel and tire combinations, which makes tire selection more involved than simply matching the model name. The listings here span several distinct size conventions and more than one wheel diameter. The first check on any La Salle 8 Cyl. should be the actual rim diameter on the car, because the range moves from 20-inch to 19-inch and later 16-inch fitments.
La Salle 8 Cyl. Tire Size Guide
La Salle 8 Cyl. production changed wheel diameters during this range, moving from 20-inch fitments to 19-inch fitments in 1929 and then to 16-inch fitments by 1935. Across 1928 to 1935, this model group uses 7 distinct tire sizes. Several of these are antique diameter-by-section sizes, where the leading number gives the tire’s outside diameter in inches rather than the wheel diameter, so the rim size must be confirmed separately.
30X5.77 is an antique-format size listed for 1928 La Salle 8 Cyl. applications. In this format, 30 indicates an overall tire diameter of about 30 inches and 5.77 indicates the section width, but the wheel diameter is not contained in the code itself. Use this size only after matching the exact 1928 configuration on the car, since the size code alone does not identify the rim diameter.
30X5 is listed for 1928 La Salle 8 Cyl. applications and has available products built for a 20-inch rim. The 30 refers to the tire’s approximate outside diameter in inches and the 5 refers to section width, while the actual wheel size comes from the product specifications and is 20 inches here. Choose 30X5 when the car’s 1928 wheel and original sizing point to this exact format rather than one of the other 1928 options; A tube is required.
32X6.20 is another antique-format size used on 1928 La Salle 8 Cyl. applications. Here, 32 denotes the tire’s overall diameter in inches and 6.20 denotes section width, but the code still does not reveal the wheel diameter. Select this size only after identifying the specific 1928 configuration, because that model year carries several different tire listings with different dimensional meanings.
650-20 applies to 1928 La Salle 8 Cyl. fitments and the available products use a 20-inch rim. In numeric bias-ply sizing, 650 represents a nominal section width of roughly 6.50 inches and 20 is the wheel diameter in inches. Choose 650-20 when the car has the later 20-inch numeric-size setup rather than one of the antique-format 1928 options; A tube is required.
31X6.20 is listed for 1929 La Salle 8 Cyl. applications. The 31 gives the approximate outside diameter in inches and 6.20 gives the section width, while the wheel diameter must be confirmed separately because it is not encoded in the size. Use this size only when the car’s 1929 wheels and existing tire markings match this older diameter-by-section convention.
650-19 fits 1929 La Salle 8 Cyl. applications and the available products are built for a 19-inch rim. In this numeric bias-ply code, 650 indicates a nominal section width of about 6.50 inches and 19 is the wheel diameter in inches. Choose 650-19 for 1929 cars that use the 19-inch wheel setup, especially where a period-style blackwall or wide whitewall bias-ply tire is desired; A tube is required.
700-16 is the listed size for 1935 La Salle 8 Cyl. applications and all available products use a 16-inch rim. In numeric bias-ply sizing, 700 indicates a nominal section width of roughly 7.00 inches and 16 is the wheel diameter in inches. Choose 700-16 for 1935 cars after confirming the later 16-inch wheel setup, and note that the offerings include both passenger-car and military or truck-style bias-ply patterns; A tube is required.
A 1928 La Salle 8 Cyl. can carry several very different tire listings, so identify the specific configuration first; that year includes a rim-diameter split involving 20-inch wheels as well as multiple size conventions.
La Salle 8 Cyl. Tires by Year
The year listing below separates La Salle 8 Cyl. tire sizes by production year so you can narrow the choices before comparing products. La Salle 8 Cyl. production changed from 20-inch to 19-inch wheels in 1929 and then to 16-inch wheels by 1935, so confirm which rim diameter the specific car carries before selecting a tire. In 1928, more than two sizes are listed, so the car’s exact wheel and configuration matter just as much as the model year.

Frequently Asked Questions
The questions below focus on the points that matter most with La Salle 8 Cyl. tires: which sizes fit which years, how the early antique-style size codes differ from later numeric sizes, and how wheel diameter changes affect selection.
Size Basics & Fitment
La Salle 8 Cyl. uses 30X5.77, 30X5, 32X6.20, and 650-20 in 1928, 31X6.20 and 650-19 in 1929, and 700-16 in 1935. Among the sizes with product coverage, 30X5 uses a 20-inch rim, 650-20 uses a 20-inch rim, 650-19 uses a 19-inch rim, and 700-16 uses a 16-inch rim. The antique-style sizes such as 30X5.77, 32X6.20, and 31X6.20 do not place the wheel diameter in the code itself.
Start with the exact year, then verify the actual wheel diameter on the car before choosing a tire. That step is especially important on La Salle 8 Cyl. because the range spans several sizing systems and more than one wheel diameter, so a car can be correctly identified by model name yet still need a very different tire.
On a La Salle 8 Cyl., 30X5 is an antique diameter-by-section size used in 1928. The first number, 30, is the tire’s approximate outside diameter in inches, and the second number, 5, is the section width. It does not mean a 30-inch wheel, and the available products for this size are built for a 20-inch rim.
That distinction matters because antique size codes can be misleading to modern buyers who are used to the wheel diameter appearing at the end of the size. If your La Salle 8 Cyl. still carries early wheel equipment or older tire markings, match both the size code and the actual rim before moving forward, and remember that bias-ply tires in this format require tubes.
A 1928 La Salle 8 Cyl. shows four listed sizes because that year includes multiple fitment paths rather than one universal tire. The group includes antique-format sizes like 30X5.77, 30X5, and 32X6.20, along with the numeric 650-20 size. That means the split is not just one simple notation difference; 1928 sits in a transition where wheel and tire specifications could vary by configuration.
Treat a 1928 La Salle 8 Cyl. as a car that needs physical verification, not just a year lookup. Check the wheel diameter, read any surviving sidewall markings, and compare against original service information or a marque specialist so you can sort out whether the car belongs in one of the antique-format sizes or the 20-inch numeric-size group.
La Salle 8 Cyl. uses more than one rim diameter across the years covered here. The listed sizes with product coverage show 20-inch rims in 1928, 19-inch rims in 1929, and 16-inch rims in 1935. On antique-format sizes such as 30X5 and 31X6.20, the wheel diameter is not revealed by the size code itself, which is why the rim must be checked separately.
The practical takeaway is simple: measure or confirm the wheel before choosing a tire, especially on an early car with replacement wheels, mixed parts, or old restoration work. On La Salle 8 Cyl., wheel diameter is the first sorting point because moving from 20 to 19 and then 16 inches changes the entire tire selection path.
Buying the Right Tire
A 1928 La Salle 8 Cyl. can take 30X5.77, 30X5, 32X6.20, or 650-20, so the correct choice depends on the specific wheel and tire setup on the car. The most direct checks are the actual rim diameter, any surviving tire size markings, and whether the car uses an antique diameter-by-section code or the later numeric code. If the car currently has 20-inch wheels, that still does not automatically narrow it to one size because both 30X5 and 650-20 are present.
Work from the car outward rather than from the year inward. Inspect each wheel, compare all five if a spare is present, and use original paperwork or marque-club guidance to confirm whether the car should wear one of the early oversized formats or the numeric 20-inch setup before selecting a replacement tire.
La Salle 8 Cyl. tire offerings here include both blackwall and wide whitewall sidewall styles. Blackwalls appear across 30X5, 650-20, 650-19, and 700-16, while wide whitewalls are available in 30X5, 650-20, 650-19, and 700-16 as well. That gives buyers a choice between a more restrained period look and a brighter whitewall presentation depending on the size and year.
For a restoration-minded La Salle 8 Cyl., sidewall choice should follow the era and the car’s intended look rather than personal preference alone. A touring or preservation-style car may call for a plainer blackwall appearance, while a fully restored show presentation may suit a wide whitewall if that look aligns with the period and the car’s trim level.
The available La Salle 8 Cyl. tire listings include Hartford, Firestone, Denman, Deka, Lester, Excelsior, Avon, BFGoodrich, Tornel, and STA. Not every brand appears in every size, and some are passenger-car offerings while others are military or truck-style patterns in the same nominal size. Firestone has the broadest presence across the listed sizes, with both blackwall and wide whitewall options represented.
Brand choice on a La Salle 8 Cyl. usually comes down to the exact size you need, the sidewall appearance you want, and whether the car is being restored for period presentation or fitted for utility-style use. Once the size and wheel diameter are settled, compare the remaining brand options by series style and intended use rather than choosing by name alone.
La Salle 8 Cyl. tire offerings span several distinct series families, including Hartford Aero, Firestone Classic Bias Ply, Highway Classic Truck, Deka Classic Truck, Firestone Balloon, Lester Classic Bias Ply, Comp H, Traction Mileage, Silvertown Classic Bias Ply, Firestone Classic Military, Tornel Classic Truck, and Military NDT. Those names point to different tread themes and intended character, from passenger-car bias-ply and balloon-style designs to military and truck-oriented patterns. All listed products are bias-ply, but they are not all aimed at the same look or use.
For a La Salle 8 Cyl. restored to passenger-car appearance, classic bias-ply or balloon-style series will usually align better than military or truck treads. Utility-type patterns may share the size, yet they change the visual character of the car, so the right series depends on whether your priority is historical presentation, touring appearance, or a more rugged tread style.
Maintenance & Longevity
A La Salle 8 Cyl. should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, ozone sources, and petroleum contamination. Bias-ply collector tires also benefit from being kept at proper inflation during storage so the sidewalls are not carrying uneven loads. Long periods on one spot can flatten the casing temporarily or stress older constructions.
If the car will sit for months at a time, roll it slightly from time to time or place it on stands in a way that does not strain the suspension or wheel hardware. Keep the tires clean with mild soap and water only, and inspect the tubes and valve stems during seasonal checks because tube-type systems age as a set, not just at the tread surface.
Tires on a La Salle 8 Cyl. should be inspected before every meaningful drive and more thoroughly at least seasonally, even if the car covers very few miles. On older bias-ply and tube-type tires, cracking, weather checking, sidewall distortion, tread separation, and valve stem condition deserve close attention. Cars from this era often spend long periods parked, which can hide deterioration until the next outing.
Use each inspection to check inflation, bead seating, uneven wear, and whether all tires on the car still match in size and construction. A collector car that looks fine at a glance can still have age-related issues, so a careful hands-on inspection is more valuable than relying on tread depth alone.
A La Salle 8 Cyl. tire should be replaced when age, cracking, casing changes, impact damage, or tube-related deterioration make continued use questionable, even if the tread still appears deep. Collector tires often age out long before they wear out because the rubber and carcass spend more time sitting than rolling. Any tire showing structural concerns should be taken out of service promptly.
That rule is even more important on a low-mileage vintage car because old-looking tread can create a false sense of security. If a La Salle 8 Cyl. carries an older tire of uncertain age, or a period piece that has spent years mounted or stored, have it evaluated by a specialist and err on the side of replacement for road use.
Restoration & Authenticity
La Salle 8 Cyl. does not point to one single original tire across the entire range here. The listed years use multiple size systems, including antique diameter-by-section sizes in 1928 and 1929, numeric bias-ply sizes such as 650-20 and 650-19, and later 700-16 sizing by 1935. Available series also span classic bias-ply, balloon, and truck or military-oriented patterns rather than one uniform original-style construction family.
For an accurate restoration, the best path is to match the exact year and wheel equipment on the car, then compare that against factory literature, period photos, or La Salle marque references. That approach matters more than choosing by brand name alone, because the right size and visual style will usually influence authenticity more than the badge on the sidewall.
Correct tire fitment can absolutely affect how a La Salle 8 Cyl. is judged and how convincing the restoration appears. Size, wheel diameter, sidewall style, and tread family all contribute to whether the car looks period-appropriate for its year. A car wearing the wrong overall diameter or an obviously utility-style tread can change its stance and presentation even if the tire technically mounts.
For show, preservation, or higher-end restoration work, use the tire decision as part of the car’s overall historical presentation. Marque clubs, period photographs, and surviving factory references are the strongest guides when you are trying to balance road usability with the kind of visual accuracy that judges and knowledgeable collectors tend to notice first.
La Salle 8 Cyl. tire options here include both blackwall and wide whitewall choices, and either can be appropriate depending on the year, presentation style, and restoration goal. Blackwalls are available in every supported product group, while wide whitewalls are also offered in the key passenger-car sizes. That gives restorers flexibility without forcing the car into one cosmetic look across all years.
Choose the sidewall style that matches the character you want the finished La Salle 8 Cyl. to project. A more restrained or earlier appearance may favor blackwalls, while a fuller concours-style presentation may call for wide whitewalls if they suit the period and trim. Consistency across all mounted tires, including the spare, helps the finished car look intentional and correct.
Safety & Road Use
A properly selected, properly mounted La Salle 8 Cyl. bias-ply tire can be suitable for public-road use when the rest of the car is equally sound and the tire matches the wheel diameter and intended application. The important limits are that these are vintage-style constructions, many are tube-type fitments, and some listed products are military or truck-pattern tires rather than passenger-car touring designs. Safety depends on the complete combination, not the size name alone.
Before road use, make sure the car has a matched set, correct inflation for the tire and wheel, and no hidden age or casing issues. A La Salle 8 Cyl. with restored brakes, steering, suspension, and properly chosen tires can be enjoyed sensibly, but it should always be driven with the expectations appropriate to a pre-war luxury car on period-style rubber.
Before driving a La Salle 8 Cyl., check inflation pressure, visible sidewall condition, tread security, valve stems, and whether all tires match in size and construction. Confirm that the tires are seated correctly on the rims and that the spare, if carried, is also serviceable. On a vintage bias-ply car, steering and brake condition matter just as much as tire appearance.
A short pre-drive routine goes a long way on a collector car. Walk around the car, look for sidewall bulges or cracks, feel for anything unusual after the first few miles, and avoid assuming that an attractive older restoration is road-ready without fresh mechanical and tire checks each season.
A La Salle 8 Cyl. on vintage-style bias-ply tires should be driven at moderate, sensible speeds that respect both the car’s age and the characteristics of tube-type pre-war tire construction. Even when the tire size is correct, these cars were designed in a very different motoring environment from modern highway traffic. Stability, braking distance, and steering response all need more margin than a modern car.
The best rule is to drive a La Salle 8 Cyl. at a pace that keeps the car composed and leaves room for correction, especially on crowned roads, grooves, or abrupt lane changes. If the car is newly restored or newly fitted with tires, begin with shorter local outings and evaluate how it tracks and brakes before attempting sustained higher-speed touring.
