Locomobile 48 Tires

Locomobile 48 fitments for 1926 and 1927 include two listed sizes: 33X6.75 and 700-21. The 700-21 size uses a 21-inch rim, while 33X6.75 is an antique diameter-by-section size where the wheel diameter is not stated in the size code itself. Both sizes appear in both model years rather than being split by year.

That means year alone is not enough to choose a tire for a Locomobile 48. Start by inspecting the wheel on the car and the markings on any existing tire, then compare that to the year listing and the wheel dimensions already fitted to the vehicle.

On a Locomobile 48, 33X6.75 is an older diameter-by-section size marking. The 33 refers to the tire's approximate overall outside diameter in inches, and the 6.75 refers to nominal section width. Unlike a modern or numeric balloon size, it does not directly name the wheel diameter in the code.

That distinction matters because many buyers understandably assume the first number is the wheel size. If your Locomobile 48 is wearing a diameter-by-section tire, inspect the actual wheel and compare the current setup carefully before choosing a replacement, since the code alone does not finish the fitment job.

A 1926 Locomobile 48 has two listed sizes because both 33X6.75 and 700-21 appear for that year. The split is not between different model years, since the same two sizes also appear for 1927. It reflects the fact that more than one tire format was used within the Locomobile 48 range during this short production window.

The practical takeaway is to identify the actual wheel and existing tire convention on your own car before selecting a replacement. Cars that have been restored, re-bodied, or re-wheeled over the decades can differ from what an owner expects just from the year stamped on the title.

Locomobile 48 tire applications in the listed range are bias-ply types, and the available 700-21 products are bias-ply as well. For period bias-ply collector tires of this style, a tube is required. That is especially important with older wheel designs that were built around tube-type construction rather than modern tubeless practice.

When replacing tires on a Locomobile 48, plan the tire, tube, and flap arrangement as one system rather than treating the outer casing by itself. Tube condition, rim condition, and correct installation are all part of getting a large pre-war luxury car ready for safe, low-use collector service.

A 1927 Locomobile 48 can use either 33X6.75 or 700-21, so the first step is to inspect what is physically on the car. Read any surviving sidewall markings, measure the wheel where possible, and check whether the setup follows an antique diameter-by-section convention or a 21-inch numeric balloon size. Both formats are period types, but they are not interchangeable by name alone.

Good fitment work on a Locomobile 48 starts with the wheel, not with assumptions. Original paperwork, older restoration records, and marque specialists can help confirm whether the car should stay with its current arrangement or return to another listed size during a restoration.

The available 700-21 Locomobile 48 products include blackwall, wide whitewall, and double-whitewall sidewall styles. Those options span a restrained touring look through a more formal late-1920s luxury appearance. All of them are offered within bias-ply collector tire lines rather than modern radial styling.

For a Locomobile 48 restoration, sidewall choice should follow the presentation you want from the car as much as the size itself. Blackwalls generally suit a more understated period look, while whitewall variations can better match a highly finished concours or formal presentation.

Current Locomobile 48 coverage in 700-21 includes Firestone, Michelin, Lester, and Excelsior. Those products appear in several collector-oriented series, including Firestone Balloon, Michelin Double Rivet, Lester Classic Bias Ply, and Excelsior Comp H. All of the listed products for this size are bias-ply constructions.

Brand choice on a Locomobile 48 usually comes down to the balance you want between visual character, series design, and restoration priorities. Once the correct size and wheel diameter are established, comparing sidewall style and series appearance becomes a more useful next step than choosing by brand name alone.

Locomobile 48 products in 700-21 appear in several series, including Firestone Balloon, Michelin Double Rivet, Lester Classic Bias Ply, and Excelsior Comp H. Those names represent different collector tire lines within the same general late-1920s bias-ply world, rather than a mix of modern constructions. Rim width guidance also varies by product, with some 700-21 offerings aimed at different wheel width ranges.

For a Locomobile 48 owner, that means the right series is not only about appearance but also about matching the wheel already on the car. Once the basic size is confirmed, compare series style, sidewall treatment, and rim width compatibility to narrow the field intelligently.

A Locomobile 48 should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and prolonged moisture. Heavy luxury cars of the 1920s place real static load on their tires, so long periods of immobility can encourage flat spotting and stress the casing. Clean floors and stable temperatures help preserve both rubber and tube-type assemblies.

If the Locomobile 48 will sit for extended periods, move it slightly from time to time or support it appropriately to reduce constant load in one spot. Tire pressure should be checked regularly during storage, because an underinflated collector tire deteriorates more quickly even when the car is not being driven.

Tires on a Locomobile 48 should be inspected before every meaningful drive and again during routine garage checks throughout the season. On a pre-war collector car, inspection should include sidewalls, tread, tube-type valve areas, wheel condition, and any signs of cracking, separation, or irregular shape. Because these cars are often driven infrequently, age-related issues can appear even when tread wear is minimal.

A brief visual look is not enough on a Locomobile 48 that has spent years in storage or recently returned to service. If anything looks uneven or period wheels show corrosion or damage, a specialist familiar with antique and pre-war tires should inspect the assembly before the car is driven further.

A Locomobile 48 tire should be replaced when age, cracking, hardening, out-of-round condition, damage, or casing deterioration appears, even if the tread still looks usable. Collector cars often age out their tires long before they wear them out. Tube-type pre-war applications deserve a conservative approach because the consequences of running an old casing on a heavy luxury car can be serious.

Replacement decisions on a Locomobile 48 should be guided by condition and age rather than mileage alone. If the car has sat for many years, have both the tire and the tube assembly evaluated together, since a sound-looking exterior can still hide age-related weakness that only appears under load.

Locomobile 48 listings for 1926 and 1927 include both 33X6.75 and 700-21, which shows that more than one period-appropriate size convention is associated with the model. Available replacement products for 700-21 include series such as Firestone Balloon, Michelin Double Rivet, Lester Classic Bias Ply, and Excelsior Comp H. That gives restorers several historically styled directions, but not one single universal answer for every car.

For a restoration-minded Locomobile 48 owner, the best reference is the individual car itself along with original literature, period photos, and marque expertise. The goal is to match the wheel, the tire format, and the car's intended presentation rather than assuming one listed size applied identically to every surviving example.

Correct tire fitment can absolutely affect how a Locomobile 48 is judged and perceived, especially because it is a high-end pre-war American car where stance, wheel proportion, and period presentation matter. An obviously incorrect size or sidewall treatment can change the car's visual balance and undermine the authenticity of an otherwise strong restoration.

Judging standards are not identical across events, so Locomobile 48 owners should align tire choice with the rules and expectations of the club or venue that matters to them most. Even outside formal judging, accurate tires usually support stronger historical credibility and a more convincing finished restoration.

Locomobile 48 tire offerings in 700-21 include blackwall, wide whitewall, and double-whitewall styles. Each of those can suit a period restoration depending on the exact character of the car and how it is being presented. On a late-1920s luxury automobile, sidewall treatment plays a major role in the final visual impression.

A Locomobile 48 restored for a restrained touring look may lean toward blackwalls, while a highly formal or show-oriented car may better suit one of the whitewall options. The most accurate choice should follow period imagery, surviving car history, and the overall restoration standard you are trying to achieve.

Properly fitted collector tires can be suitable for careful public-road use on a Locomobile 48 when the full car is mechanically sound and the tire assemblies are correctly matched to the wheels. The listed products for 700-21 are bias-ply tires intended for period-style service, not modern high-speed touring. Safety depends on the condition of the wheel, tube, inflation, steering, brakes, and suspension as much as the tire itself.

A Locomobile 48 should be driven with the expectations appropriate to a large pre-war luxury car rather than a modern sedan. Shorter outings, conservative speeds, and regular inspection are the right mindset, especially after long storage or recent restoration work.

Before driving a Locomobile 48, check tire inflation, visible sidewall condition, wheel security, valve stems, and any signs of casing distortion or cracking. Because the car uses period-style bias-ply tires, it is also wise to look at overall tread seating and whether the tire appears to be resting evenly on the wheel. A pre-drive walkaround matters more on low-use collector cars than on daily drivers.

On a Locomobile 48, tire checks should be part of a broader mechanical review that includes brakes, steering response, and wheel bearing condition. Any vibration, pull, or unusual feel once moving should be taken seriously and investigated before the car is driven farther.

A Locomobile 48 on period-style bias-ply tires should be driven at moderate, conservative speeds that respect the age and design of both the car and its tire construction. Even with new collector tires, the driving experience is fundamentally different from a modern radial-equipped vehicle. Stability, braking distance, and steering response all reflect 1920s engineering priorities rather than present-day highway expectations.

The right approach with a Locomobile 48 is to let road conditions, mechanical condition, and tire condition set the pace. Touring at sensible speeds and leaving a generous safety margin will usually do more for safety and preservation than trying to match the flow of modern traffic.
