The 1928 La Salle 8 Cyl. sits at an interesting point in American luxury-car history, blending Cadillac influence with a slightly newer, more style-conscious identity for the late 1920s market. Cars from this era ask for a very different tire conversation than postwar classics, because wheelbase and wheel type can change the fitment story quickly. The 1928 La Salle 8 Cyl. uses bias-ply tires, with primary sizes including 30X5.77, 30x5, 32X6.20, and 650-20 depending on configuration. That makes the real decision less about modern tire trends and more about matching the correct size, construction, and sidewall presentation to the car’s wheelbase, wheel setup, and restoration goals.
Which Tire Size Is Right for The 1928 La Salle 8 Cyl.
The 1928 La Salle 8 Cyl. uses four primary tire sizes, and the right one depends first on identifying the exact wheelbase configuration and wheel setup on the car. These are all bias-ply fitments, but they are not all built around the same sizing system or rim diameter, so confirming the specific sub-model and wheel dimensions matters before comparing appearance or product choices.
30X5.77 is an antique diameter-by-section size, where the first number refers to an approximate 30-inch overall tire diameter and the second number describes the section width. It is a bias-ply fitment used on the 1928 La Salle 8 Cyl., and its dimensions place it firmly in the prewar tire world rather than later numeric sizing conventions. This size is tied more closely to proper early-vehicle fitment than to broad product variety. It is the kind of size to evaluate carefully when preserving original wheel character, confirming rim compatibility, and keeping the tire’s visual proportions aligned with a restoration-oriented setup.
30x5 is also an antique diameter-by-section size, meaning the 30 refers to approximate overall diameter and the 5 refers to nominal section width. On a 1928 La Salle 8 Cyl., this is another bias-ply fitment rooted in early automotive sizing practice, and it differs from later numeric bias-ply sizes that reference a rim diameter directly in the size code. Because this format can be unfamiliar to modern buyers, it is worth confirming the actual wheel type before selecting a replacement. That makes 30x5 especially important for owners focused on preserving an authentic early-car stance and proper mechanical compatibility.
32X6.20 uses the same antique diameter-by-section convention, with an approximate 32-inch overall diameter and a nominal 6.20-inch section width. As a bias-ply fitment for the 1928 La Salle 8 Cyl., it reflects the larger tire requirement used on certain configurations rather than a later passenger-car sizing format. This size should be approached as a distinct fitment path, not as a variation of the smaller 30-inch options. It is most relevant when the car’s wheelbase or wheel equipment places it in the larger-tire group and the owner wants to keep the proper visual scale for the chassis.
650-20 is a numeric bias-ply size in which 6.50 refers to nominal section width and 20 identifies the rim diameter. On the 1928 La Salle 8 Cyl., it is the most developed product fitment, with choices from Firestone, Denman, and Deka in series that range from classic passenger-car styling to truck-oriented tread patterns. Sidewall treatments include blackwall and wide whitewall, giving this size more appearance flexibility than the other primary fitments. It is the size to study closely when the car uses the larger-wheel setup and the owner wants to balance restoration character with available brand and sidewall options.
Sub-model fitment matters on the 1928 La Salle 8 Cyl. because tire size changes with wheelbase configuration. Before choosing a tire, verify whether the car is the 125 inch wheelbase or 134 inch wheelbase version so the size family and wheel dimensions stay aligned with the vehicle.

1928 La Salle 8 Cyl. (125 inch wheelbase)
The 1928 La Salle 8 Cyl. (125 inch wheelbase) uses the smaller of the two fitment groups, centered on antique-style bias-ply sizing rather than the larger 20-inch numeric bias-ply setup. Tire selection here is mainly about confirming the exact wheel type and choosing a period-style replacement that matches the car’s early construction and proportions.
The 1928 La Salle 8 Cyl. (134 inch wheelbase) uses the larger fitment group, including 32X6.20 and 650-20 bias-ply sizing. That gives this configuration a broader product path in 650-20, so buyers should first confirm which of the two larger sizes the car actually uses before comparing brands, sidewall styles, and series.
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 1928 La Salle 8 Cyl. Tires for Sale
Available 650-20 choices include Firestone, Denman, and Deka options in classic bias-ply and truck-oriented series, with blackwall and wide whitewall sidewall treatments. The product grid is most useful for comparing appearance, series character, load specifications where stated, and rim-width compatibility within this 20-inch fitment.
Owners researching 1928 La Salle 8 Cyl. tires usually need to sort out wheelbase-specific sizing first, then compare early bias-ply formats, 20-inch rim fitment, available sidewall styles, and the practical checks that matter before returning a collector car to road use.
Tire Size & Fitment
What tire size fits a 1928 La Salle 8 Cyl.?
The 1928 La Salle 8 Cyl. uses four primary tire sizes: 30X5.77, 30x5, 32X6.20, and 650-20. These are all bias-ply fitments, but they do not apply universally across every configuration because wheelbase and wheel setup affect which size belongs on the car.
The 125 inch wheelbase and 134 inch wheelbase versions do not share the same tire group, so the first step is confirming which La Salle you have. After that, check the actual wheels on the vehicle, especially on an older restoration, because early cars may have had wheel or tire changes over time that alter what size should be selected now.
What size rim does a 1928 La Salle 8 Cyl. use?
Rim diameter on the 1928 La Salle 8 Cyl. is not the same across every fitment. The 30X5.77 tire uses a 7-inch rim diameter, while the 650-20 fitment uses a 20-inch rim. That difference reflects the very different sizing systems found on late-1920s vehicles.
The size stamped on the tire can look unfamiliar, especially with antique diameter-by-section fitments, so checking the wheel itself is just as important as reading the sidewall. A buyer should confirm the wheel diameter and style already on the car before choosing a replacement, particularly if the vehicle has been restored, stored for years, or fitted with non-original wheels at some point.
Do all 1928 La Salle 8 Cyl. sub-models use the same tire size?
No, the covered sub-models do not all use the same tire size. The 125 inch wheelbase La Salle uses 30X5.77 and 30x5, while the 134 inch wheelbase version uses 32X6.20 and 650-20. All of these are bias-ply fitments, but they belong to two different size groups.
That means sub-model identification is not just a minor detail; it is the starting point for correct tire selection. Once the wheelbase is confirmed, compare the actual wheel and existing tire setup on the car so the replacement matches the chassis and avoids mixing early antique-style fitments with the larger 20-inch numeric bias-ply option.
Choosing the Right Tire
What should I consider when choosing a 650-20 tire for a 1928 La Salle 8 Cyl.?
A 650-20 tire for a 1928 La Salle 8 Cyl. should first be matched to the correct sub-model and wheel setup, since this size belongs to the larger fitment group. Available choices differ by brand, sidewall treatment, tire series, weight, and in some cases stated load capacity and rim-width range.
Firestone offers both classic passenger-style and truck-style 650-20 options, while Denman and Deka add additional blackwall choices with truck-oriented character. The best way to narrow the field is to decide whether the car needs a more formal restoration-style appearance, such as a wide whitewall, or a more utilitarian blackwall presentation that suits the vehicle’s intended use.
What sidewall styles are available for 1928 La Salle 8 Cyl. tires?
Within the available 650-20 product selection for the 1928 La Salle 8 Cyl., sidewall styles include blackwall and wide whitewall. That gives owners a meaningful appearance choice even while staying within the correct size family for the larger-wheel configuration.
Sidewall style changes the car’s presentation more than many buyers expect, especially on a late-1920s luxury automobile with tall tires and open visual space around the wheels. A wide whitewall creates a more formal restoration-oriented look, while a blackwall keeps the presentation plainer and more utilitarian, so the decision should match the car’s trim level, finish style, and use.
What brands offer tires for the 1928 La Salle 8 Cyl.?
For the 650-20 fitment used on certain 1928 La Salle 8 Cyl. configurations, available brands include Firestone, Denman, and Deka. Those choices appear across classic bias-ply passenger and truck-style tire series, giving buyers more than one path depending on the look and character they want.
Brand alone should not drive the decision on an early car like this. It is smarter to start with the correct size and wheel setup, then compare sidewall style, series type, rim-width specification where stated, and any load information included with the tire so the final selection suits both the vehicle and its intended road use.
Restoration & Appearance
Which tire should I choose for a period-style 1928 La Salle 8 Cyl.?
A period-style 1928 La Salle 8 Cyl. should begin with the correct primary size for its wheelbase and wheel setup, since the car uses different bias-ply size groups. For the larger 650-20 fitment, the available choices include both blackwall and wide whitewall options, which can shape the finished appearance significantly.
For a restoration-minded car, matching the proper size and overall visual proportion matters more than chasing modern substitutes. When exact historical presentation is important, the final sidewall and brand decision should also be checked against marque references, period photographs, or restoration documentation so the tire complements the car rather than simply filling the wheel opening.
Does correct tire fitment matter for a 1928 La Salle 8 Cyl. restoration?
Yes, correct tire fitment matters a great deal on a 1928 La Salle 8 Cyl. because the tire is such a visible part of the car’s stance, wheel opening fill, and overall period character. Using the wrong size group can make the car look out of scale and may also create avoidable fitment complications.
Early vehicles rely heavily on proper tire proportion to look right, so restoration decisions should start with wheelbase-specific sizing rather than appearance alone. Once the correct fitment family is confirmed, buyers can choose between sidewall presentations such as blackwall or wide whitewall to support the finished style without drifting away from the vehicle’s proper late-1920s visual balance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1928 La Salle 8 Cyl.?
Yes, modifications can affect tire fitment on a 1928 La Salle 8 Cyl., especially because this vehicle already spans more than one size family and more than one rim diameter. Wheel changes, brake updates, altered ride height, or replacement rims from another period vehicle can all change what tire size is appropriate.
A car from 1928 may also have had decades of repairs or restoration work, so the current setup deserves a close inspection before new tires are chosen. Measure the installed wheels, confirm the diameter and width, and check clearance around fenders, steering travel, and suspension movement so the tire selected matches the car as it sits today.
What should I inspect before driving a 1928 La Salle 8 Cyl. on new tires?
Before driving a 1928 La Salle 8 Cyl. on new tires, inspect the wheels for damage or age-related issues, confirm that the tire size matches the car’s actual configuration, and make sure the tires are mounted and inflated appropriately for their application. Early cars also deserve a close look at steering and brake condition before road use.
A fresh set of tires cannot compensate for loose steering parts, worn suspension components, or improper wheel condition. It also helps to recheck lug security, look for any rubbing during low-speed turning, and watch for air loss after installation, since collector vehicles often spend long periods parked and may reveal issues only once they return to regular motion.
How should tires on a collector 1928 La Salle 8 Cyl. be maintained?
Tires on a collector 1928 La Salle 8 Cyl. should be inspected regularly for cracking, cuts, bulges, uneven wear, and loss of air pressure, even if the car is driven only occasionally. Low annual mileage does not stop rubber from aging, and long storage periods can be just as important as road use in tire condition.
Proper storage helps preserve both appearance and service life. Keep the car away from prolonged sunlight, heat, moisture, and ozone sources, and move it occasionally if it sits for extended periods so the tires are not carrying weight in one spot for too long. Any sign of age or condition change should be evaluated before the next road outing.
