Oldsmobile Series 25 Tires
Oldsmobile Series 25 belongs to the brass era of American motoring, when touring cars and runabouts still carried tall, narrow tires and road manners were shaped as much by wheel and tire design as by the chassis itself. Built for 1910, Oldsmobile Series 25 comes from a period when tire sizing followed conventions that can easily confuse modern buyers because the size marking does not directly name the wheel diameter. Choosing correctly is less about sorting through many years of production and more about understanding the period size format and matching it to the proper rim. The first thing to verify on an Oldsmobile Series 25 is the actual wheel and rim diameter.
Oldsmobile Series 25 Tire Size Guide
Oldsmobile Series 25 uses one tire size across its production span, 36X4 for 1910. This is an antique diameter-by-section size, so the 36 identifies the tire's overall outside diameter in inches and the 4 identifies the section width, while the actual rim diameter is 28 inches. Available products in this size include brass-era bias-ply offerings from Firestone, Diamond, BFGoodrich, and Universal Vintage Tire in blackwall, all white, and wide whitewall styles. A tube is required. One product in this size is listed as new-old-stock original period production, and one product in this size is a made-to-order item.
Oldsmobile Series 25 Tires by Year
The year listing for Oldsmobile Series 25 shows which tire size applies to each production year and helps confirm the correct fit before moving on to construction and sidewall choices. The leading number in the size code is the tire's outside diameter, not the wheel size, so the rim diameter must be checked on the wheel or in the product specifications. Because Oldsmobile Series 25 is a short-run brass-era application, confirm the tire size against original vehicle paperwork or a knowledgeable marque specialist.

Frequently Asked Questions
The FAQ for Oldsmobile Series 25 focuses on the brass-era 36X4 size format, the 28-inch rim it fits, tube-type bias-ply construction, and the practical differences between current production offerings and the listed new-old-stock tire.
Size Basics & Fitment
Oldsmobile Series 25 uses one listed tire size: 36X4 for 1910. That size fits a 28-inch rim in the available products for this application, and all listed tires are bias-ply brass-era style offerings. The available choices cover several period-looking tread and sidewall presentations, but the underlying fitment remains the same 36X4 size on a 28-inch rim.
That makes size selection more straightforward than on later cars with multiple year splits, but it also means the buyer needs to interpret the old-style size code correctly. Start by confirming the wheel on the car is the proper 28-inch rim, then choose among the available period-style constructions and sidewall treatments according to how the Oldsmobile Series 25 will be shown, driven, or restored.
On an Oldsmobile Series 25, 36X4 is an antique diameter-by-section size rather than a modern wheel-diameter-first code. The 36 refers to the tire's overall outside diameter in inches, and the 4 refers to the nominal section width. It does not mean the tire fits a 36-inch wheel. The listed products for this size fit a 28-inch rim.
That distinction matters because many early tire markings look larger than the wheel they actually mount on. When evaluating an Oldsmobile Series 25, treat the 36X4 marking as a dimensional description of the tire itself, then verify the rim diameter separately on the wheel. Doing that avoids the most common brass-era fitment mistake and keeps the search centered on the proper tire and tube combination.
The listed 36X4 tires for Oldsmobile Series 25 use a 28-inch rim. That rim diameter comes from the tire specifications for the available products, not from the 36X4 size marking itself. Because this is an antique format, the wheel size must always be read separately from the tire code.
A quick check of the actual wheel is worthwhile before selecting a tire, especially on a brass-era car that may have seen parts interchange over many decades. Confirming the 28-inch rim first lets you narrow the choice to the correct casing, tube-type setup, and preferred sidewall appearance without confusion over the larger number shown in the vintage size designation.
Oldsmobile Series 25 should be treated as a tube-type application. The available 36X4 products are bias-ply brass-era tires in an antique size format, and that style of fitment requires a tube. Nothing in the available range suggests a modern tubeless radial construction for this application.
For a restoration or a roadworthy brass-era setup, the tire, tube, and rim condition need to work together as a system. If the wheel has any age-related wear, rust, or irregularity, address that before mounting new tires. Proper tube selection and careful mounting are especially important on Oldsmobile Series 25 because the tall, narrow casing depends heavily on correct assembly to run as intended.
Buying the Right Tire
Oldsmobile Series 25 tires are available in blackwall, all white, and wide whitewall presentations within the listed 36X4 offerings. Firestone and Universal Vintage Tire appear in blackwall form, Diamond and Universal Vintage Tire appear in all white, and the BFGoodrich Silvertown Cord new-old-stock tire is listed with a wide whitewall. All of them remain within the same basic size fitment.
The right sidewall style depends on how the Oldsmobile Series 25 is being restored and presented. Brass-era cars often look appropriate with either black or white treatments depending on restoration goals, touring style, and judging expectations. If authenticity is the priority, compare the car against period photos, original literature, or marque-club guidance before choosing a sidewall treatment simply for appearance.
Four brands appear in the listed Oldsmobile Series 25 tire range: Firestone, Diamond, BFGoodrich, and Universal Vintage Tire. Those brands cover several different period-style series in 36X4, including Firestone High Pressure, Diamond Smooth Tread, Silvertown Cord, and Universal Classic Bias Ply. The group gives buyers more than one approach to period appearance within the same fitment.
Brand choice on an Oldsmobile Series 25 usually comes down to restoration intent, preferred tread style, and whether the car is being prepared for touring, exhibition, or a historically themed presentation. Once the size and rim diameter are confirmed, compare the available series and sidewall styles rather than assuming every 36X4 offering creates the same visual or period effect on the car.
One listed Oldsmobile Series 25 tire is identified as made to order: the Universal Vintage Tire blackwall 36X4. In this context, made to order is a product characteristic that distinguishes it from the other brass-era offerings in the size. It does not change the basic fitment, which remains 36X4 on a 28-inch rim.
For the buyer, the practical point is to separate fitment from product status. Confirm first that the Oldsmobile Series 25 needs the 36X4 tube-type bias-ply size, then decide whether a made-to-order blackwall presentation suits the car better than the other available period styles. That keeps the selection process centered on correctness and restoration goals rather than on the product label alone.
The listed new-old-stock option for Oldsmobile Series 25 is a BFGoodrich Silvertown Cord 36X4 with a wide whitewall. New-old-stock means original period production rather than a newly manufactured tire. Even when an NOS tire looks visually appealing, age alone can affect rubber integrity, casing condition, and roadworthiness in ways that are not obvious from appearance.
That makes an NOS tire most appropriate for carefully evaluated use, often with a strong bias toward display or very limited specialist-supervised operation. If the goal for Oldsmobile Series 25 is regular event driving, many restorers prefer newly manufactured period-style tires and reserve NOS pieces for authenticity displays. Specialist inspection is the right next step before any NOS tire is mounted or driven.
Maintenance & Longevity
Oldsmobile Series 25 should be stored in a cool, dry, dark space away from direct sunlight, electric motors, ozone sources, and extreme temperature swings. Keep the tires clean and dry, and avoid letting the full weight of the car sit in one position for long uninterrupted periods. On a brass-era car with tall tube-type bias-ply tires, storage conditions have an outsized effect on sidewall health and casing shape.
If the car will sit for extended periods, move it occasionally or support it in a way that reduces prolonged flat-spotting while respecting the suspension and chassis. Tire pressures should be checked during storage intervals rather than only before an event. Good storage habits are one of the simplest ways to preserve the appearance and service life of Oldsmobile Series 25 tires.
Tires on an Oldsmobile Series 25 should be inspected before every drive and again after any long outing. A brass-era tube-type bias-ply tire deserves routine checks for cracking, exposed fabric, sidewall distress, tread separation signs, uneven wear, valve condition, and pressure loss. The wheel and rim flap or tube-related components should also be part of that inspection routine.
Regular inspection matters because collector cars often age out their tires long before they wear them out. On an Oldsmobile Series 25, small changes in shape or sidewall condition can become important quickly because the tire is a major part of how the car rides and steers. If anything looks questionable, have the assembly reviewed by a shop familiar with early automotive tires and wheels.
Oldsmobile Series 25 tires should be replaced when age, cracking, hardening, deformation, casing damage, recurring tube problems, or any sign of structural weakness appears, even if tread depth still looks acceptable. Collector tires often reach the end of safe service because of time and environment rather than mileage. Any new-old-stock tire on an Oldsmobile Series 25 deserves especially careful age and condition assessment before use.
That is why replacement decisions on an Oldsmobile Series 25 should center on condition and intended use rather than on tread wear alone. A car prepared for tours or public-road operation should be held to a stricter standard than one used only for static display. If there is any doubt about the integrity of the tire or tube assembly, replacement is the prudent path.
Restoration & Authenticity
Oldsmobile Series 25 is represented here by 36X4 brass-era tire offerings, with available series including Firestone High Pressure, Diamond Smooth Tread, Silvertown Cord, and Universal Classic Bias Ply. Those series show the kinds of period-style constructions and appearances associated with this early application, but they do not by themselves identify a single universally correct original brand or exact factory issue for every surviving car.
For a precise restoration, use the 36X4 size and 28-inch rim as the starting point, then compare tread style and sidewall treatment against period photographs, sales literature, and marque-club knowledge. That approach helps place the Oldsmobile Series 25 within the correct brass-era visual language without assuming that one currently available product automatically represents every original delivery configuration.
Correct tire fitment can absolutely influence the presentation, judging results, and perceived quality of a Oldsmobile Series 25 restoration. On a brass-era car, tire height, width, sidewall style, and tread character are highly visible and strongly shape the vehicle's stance. Using the proper 36X4 size on the proper 28-inch rim is a fundamental part of making the car look mechanically and historically coherent.
Judges and knowledgeable enthusiasts often notice tires immediately because they affect both authenticity and proportion. If the Oldsmobile Series 25 is being prepared for formal events, compare the chosen tire against marque standards and period imagery rather than choosing solely by modern taste. Correct fitment is rarely the only factor in value, but it is one of the easiest details to get visibly right.
Oldsmobile Series 25 tire choices in the listed 36X4 size include blackwall, all white, and wide whitewall sidewall styles. Because this is a brass-era application, more than one of those presentations can suit a historically themed restoration depending on the look being recreated. The available range gives room for a darker utilitarian appearance or a brighter period show presentation.
The correct choice for a specific Oldsmobile Series 25 depends on the car's restoration goal, surviving evidence, and the standards of the events where it will appear. Original photographs, period advertising, and club guidance are useful references when choosing between black and white sidewall presentations. Once that decision is made, keep the size and rim match correct so the sidewall style supports rather than distracts from authenticity.
Safety & Road Use
A Oldsmobile Series 25 on correctly fitted, properly mounted, and well-maintained 36X4 bias-ply tires can be moved and used within the cautious limits appropriate to a brass-era automobile, but these are not modern high-speed touring tires. The age of the vehicle, the tube-type construction, and the narrow tall casing all demand conservative expectations. Any NOS tire should be treated with even greater caution.
Public-road use should be limited to the condition of the complete car, not judged by the tires alone. Brakes, steering, wheel condition, hubs, and suspension all need to be reviewed by someone familiar with early automobiles before regular driving is considered. For many Oldsmobile Series 25 owners, restrained pleasure driving, local events, and carefully planned routes are the most appropriate uses.
Before driving a Oldsmobile Series 25, check tire pressure, visible sidewall condition, tread condition, tube valve integrity, wheel fasteners, and overall wheel condition. On a brass-era car, it is also wise to look for any shifting on the rim, uneven stance, or signs that a tube or flap issue is developing. The vehicle's mechanical systems deserve the same level of scrutiny before any road movement.
A short pre-drive routine helps catch problems while they are still manageable in the garage rather than on the roadside. Because Oldsmobile Series 25 relies on early chassis and tire technology, even a small tire issue can affect steering feel and braking confidence. If the car has been sitting for a while, a more thorough inspection is warranted before more than a brief local outing.
A Oldsmobile Series 25 should be driven at very modest speeds consistent with brass-era mechanical design and the limitations of tall, tube-type bias-ply tires. These tires are best treated as suitable for careful local driving, parade use, exhibition movement, and conservative touring rather than sustained fast road work. The goal is preserving control, mechanical sympathy, and tire integrity rather than maintaining modern traffic pace.
Prudent owners match speed to road surface, weather, traffic density, and the overall condition of the car. Even with fresh period-style tires, Oldsmobile Series 25 should be operated with generous stopping distance and smooth steering inputs. If the car carries an NOS tire, speed expectations should become even more restrained and specialist advice should shape whether road use is appropriate at all.
