1910 Oldsmobile Series 25 Tires

The 1910 Oldsmobile Series 25 uses a 36X4 tire size. This is a bias-ply antique diameter-by-section fitment, not a later numeric or metric size, and it is the primary size associated with the covered vehicle and its Standard sub-model.

That sizing system is important because the first number refers to approximate overall tire diameter, while the second refers to section width. A buyer should stay focused on the 36X4 designation and also confirm that the car still carries the correct early wheel setup, since antique tire sizing and wheel design differ substantially from later collector-car applications.

The 36X4 tire used on the 1910 Oldsmobile Series 25 is associated here with a 28-inch rim. That wheel relationship is typical of early diameter-by-section sizing, where the tire’s named diameter is not the same as the rim diameter.

This is one of the easiest places for confusion with brass-era vehicles, especially if a car has been apart for restoration or has mixed components. Before choosing a tire, measure the wheel carefully and inspect bead areas and overall wheel condition so the tire size, rim diameter, and early wheel design all remain in step.

On a 1910 Oldsmobile Series 25, 36X4 is an antique diameter-by-section tire size. The 36 refers to the tire’s approximate overall diameter in inches, while the 4 refers to its nominal section width, making it very different from modern alphanumeric or metric sizing.

Understanding that format helps prevent ordering mistakes, because a modern buyer might assume the first number reflects wheel diameter. On this fitment, the tire works with a 28-inch rim, so the size name and the wheel size are not the same thing. That difference should be confirmed before any restoration or road-use decision.

Start with the correct 36X4 size and bias-ply construction, then compare the tire’s presentation and series. For this Oldsmobile, available options span brass-era styles from Firestone, BFGoodrich, Diamond, and Universal Vintage Tire, with differences in tread character, sidewall treatment, and related product details.

After size and construction are settled, think about how the car will be used and how closely the tire’s look should follow a restoration theme. A touring-minded owner may prioritize one visual style, while a show-focused owner may prefer another. Wheel condition, rim diameter, and any load information associated with a product should also be part of the decision.

The 36X4 options for the 1910 Oldsmobile Series 25 include blackwall, all-white, and wide whitewall sidewall treatments. Those choices create noticeably different visual effects on a brass-era car, even when the primary tire size and basic construction remain the same.

Sidewall selection should follow the vehicle’s restoration direction rather than fashion alone. A blackwall can give a restrained touring look, while all-white or wide whitewall treatments create a brighter and more formal presentation. Since the size itself does not change, this is largely an appearance decision once the wheel setup and the correct 36X4 fitment have been confirmed.

Tires in 36X4 for the 1910 Oldsmobile Series 25 are available from Firestone, BFGoodrich, Diamond, and Universal Vintage Tire. Those offerings cover several period-style series, including Firestone High Pressure, Silvertown Cord, Diamond Smooth Tread, and Universal Classic Bias Ply.

Brand choice is best treated as part of a broader comparison rather than as the whole answer. Owners should look at the sidewall style, the tire series character, and any product details such as weight or stated load information where available. For an early car like this, visual harmony and correct fitment usually matter as much as the brand name itself.

A period-style 1910 Oldsmobile Series 25 should begin with the correct 36X4 bias-ply size, since the early dimensions and construction are central to the car’s brass-era stance and appearance. Within that size, the main differences come from brand, tire series, tread presentation, and sidewall treatment rather than from alternate primary fitments.

The best visual choice depends on how the car is being restored and presented. Some owners prefer a darker, more understated blackwall look, while others want all-white or wide whitewall styling that better suits a formal restoration theme. If exact historical originality matters, vehicle-specific period references and marque expertise are worth consulting before choosing a finishing detail.

On a restored 1910 Oldsmobile Series 25, the correct bias-ply construction helps preserve the narrow, tall brass-era tire profile associated with the 36X4 fitment. Construction influences more than road feel on a vehicle of this age; it also shapes the tire’s overall visual character and how naturally it suits the car’s early wheel design.

Appearance is also affected by tread style and sidewall treatment, so construction should be considered alongside those visible details. A buyer restoring the car for display will usually want the tire to support the vehicle’s era-specific proportions first, then choose between blackwall, all-white, or wide whitewall presentation to complete the look.

Yes. Even though the correct primary tire size is 36X4, modifications can change whether that tire suits the car’s actual setup. Wheel substitutions, altered hubs, non-original rims, suspension repairs using different parts, or body changes can all affect how an early tire fits and clears.

That matters especially on brass-era vehicles because the wheel and bead configuration are part of the fitment story, not just the printed tire size. Any Oldsmobile that has been restored over many decades deserves a close inspection of wheel diameter, bead area condition, and running clearance before road use, rather than assuming every surviving component remains original.

Before driving a 1910 Oldsmobile Series 25 on new tires, inspect the wheels for correct diameter, sound bead areas, cracks, corrosion, and overall structural condition. The tires themselves should be checked for proper seating, consistent inflation, and any visible irregularities before the car is moved beyond a short test distance.

An early Oldsmobile also benefits from a broader chassis check before regular road use. Steering play, brake function, wheel bearing condition, and suspension movement all influence how safely the car carries a tall brass-era tire. A cautious shakedown run is wise so heat, vibration, and clearance can be evaluated before any longer outing.

36X4 tires on a collector 1910 Oldsmobile Series 25 should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Because brass-era cars are often driven infrequently, sidewall condition, air retention, and any signs of cuts, bulges, or cracking deserve attention even when tread wear is minimal.

Storage habits matter as much as mileage on a car like this. Keeping the Oldsmobile away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps protect both tire appearance and service condition. Tires should also be inspected before each outing, since long idle periods can hide problems that only become obvious once the car returns to the road.
