1904 Vehicle Tire Fitment Guide

The 1904 vehicles covered here use five tire sizes: 28X3, 30X3, 30X3.5, 34X4, and 36X3. All of the listed applications are Bias Ply. Those sizes reflect early tire sizing conventions common to Brass Era vehicles, where dimensions were presented in a diameter-by-section style rather than the modern metric formats most drivers know today.

The most widely shared sizes in this group are 28X3 and 30X3.5, while 34X4 and 36X3 are more specialized. A 1904 Packard Model L uses 34X4, and the 1904 Studebaker Electric is the only vehicle here tied to 36X3. Because 1904 tire fitment varies noticeably by model, the best path is to start with the exact size and then confirm the vehicle application.

No. 1904 vehicles do not all use the same tire size, even within the same make. The fitment range for this year includes compact 28X3 applications, mid-range 30X3 and 30X3.5 sizes, and larger 34X4 and 36X3 sizes. That spread is typical of early automotive development, when manufacturers used different chassis, wheel, and tire combinations across their lineups.

A good example is 1904 Cadillac, which spans 28X3, 30X3, and 30X3.5 depending on model. Studebaker also shows variation, with the 1904 Studebaker Model C using 30X3.5 and the 1904 Studebaker Electric using 30X3 and 36X3. For 1904 vehicle tire fitment, year alone is not enough; exact make and model matter.

The right way to identify tires for a 1904 vehicle is to confirm the year, make, model, and the tire size associated with that exact application. For this year, the fitments include several shared sizes, but there are also model-specific applications. That means a surviving Brass Era vehicle should not be matched by make alone or by a visual estimate of tire height.

It also helps to inspect the existing wheels and any markings on the current tires, especially on restored or modified vehicles. Product details can further narrow the choice, since some 1904 sizes include listed rim diameters such as 23 inches for 30X3.5, 24 inches for 30X3, and 26 inches for 34X4. If the vehicle has had wheel or chassis changes over time, clearance and wheel dimensions should be verified before purchase.

The 1904 makes represented here are Buick, Cadillac, Ford, Oldsmobile, Packard, and Studebaker. Together, they cover a useful cross-section of Brass Era vehicle tire fitment, from smaller shared applications to larger specialty sizes. That mix gives shoppers a clear view of how 1904 tire selection can shift from one manufacturer to another.

Some makes are centered on one main size, while others span several. Ford is straightforward with 28X3 on both listed models, while Cadillac and Studebaker show broader variation. Packard stands apart with a single 34X4 application. When researching 1904 vehicle tires, knowing the make is the first step, but it should always be followed by the full model name and exact tire size.

The 1904 models covered include the 1904 Buick Model B, 1904 Cadillac Model A, 1904 Cadillac Model B, 1904 Ford Model A, 1904 Ford Model C, 1904 Oldsmobile Light Tonneau, 1904 Oldsmobile Model 6C, 1904 Oldsmobile Model N, 1904 Packard Model L, 1904 Studebaker Electric, and 1904 Studebaker Model C. Those models are distributed across five early tire sizes.

Several models share common fitments, which is helpful when comparing product choices by size. For example, 28X3 appears across Buick, Cadillac, Ford, and Oldsmobile models, while 30X3.5 is used by Buick, Cadillac, Oldsmobile, and Studebaker. At the same time, some applications are more specialized, such as 34X4 for the 1904 Packard Model L and 36X3 for the 1904 Studebaker Electric.

Yes. Different 1904 models can use different tire sizes, and in some cases a single make includes more than one fitment pattern. That is one of the defining features of this year’s tire landscape. Early vehicle design was not as standardized as later eras, so tire size often changed with chassis design, body style, or intended vehicle use.

Buick is a good example because the 1904 Buick Model B is associated with both 28X3 and 30X3.5. Oldsmobile also splits fitment, with the 1904 Oldsmobile Light Tonneau using a different size from the 1904 Oldsmobile Model 6C and 1904 Oldsmobile Model N. For shoppers, that means the exact model name should always guide the search before comparing sidewall style, brand, or series.

The available tires for 1904 vehicles are Bias Ply products in several Brass Era sizes. Depending on size, choices include Universal Vintage Tire, Coker Classic, Firestone, Michelin, and BFGoodrich offerings. Product lines include ribbed tread, smooth tread, T-Driver, clincher-style, high-pressure style, and classic bias-ply designs, with sidewall choices that vary by size.

The type of tire available depends heavily on the application. In 30X3.5, for example, there are Universal and Firestone options, including Firestone Clincher products. In 30X3, there are Coker Classic Clincher and Universal offerings. The larger 34X4 size broadens the brand mix further with Michelin, BFGoodrich, Firestone, and Universal. For 1904 vehicle tires, product type follows size-specific fitment rather than a one-style-fits-all approach.

The 1904 vehicle tires covered here are Bias Ply. That construction is consistent across the listed sizes, which range from 28X3 to 36X3. For Brass Era applications, Bias Ply construction aligns with the period-appropriate style of early automotive tires and the wheel systems used by these vehicles.

Within that shared construction type, there is still meaningful variation in product design and intended presentation. Some tires are described as clincher or beaded edge products, while others are listed in classic bias-ply or high-pressure style series. Sidewall appearance also differs by size, with Blackwall, All White, and even Wide Whitewall options appearing in certain applications. Construction stays consistent, but the product details still require careful selection.

Tire sizes vary across 1904 vehicles because manufacturers were building very different kinds of machines during the Brass Era, from smaller runabouts to larger touring and specialty vehicles. In this year’s fitments, the variety appears mostly in size rather than construction, since all listed products are Bias Ply. The differences are tied more to vehicle design, wheel dimensions, and intended use than to modern-style performance categories.

That is why a 1904 Ford Model A shares a compact 28X3 application while a 1904 Packard Model L uses a much larger 34X4. Studebaker adds another layer, with a dedicated electric model using specialized sizing. These early fitment patterns make it important to avoid assumptions based on brand name alone and instead verify the exact 1904 application before selecting a tire.

When choosing tires for a 1904 vehicle, start with the exact tire size, then consider construction, wheel dimensions where listed, and the look you want the vehicle to present. All of the covered applications are Bias Ply, but product differences still matter. Depending on size, options may include clincher-style products, ribbed tread designs, smooth tread designs, and several sidewall treatments.

For example, some 30X3.5 products are specified for 23-inch rims, 30X3 products are listed on 24-inch rims, and 34X4 products are listed on 26-inch rims. Sidewall style can also influence the final decision, especially for restoration-oriented vehicles. Blackwall, All White, and Wide Whitewall choices are not available in every size, so the best tire is the one that matches both the vehicle’s fitment and the owner’s goals.

The brands represented for 1904 vehicle tires include Universal Vintage Tire, Coker Classic, Firestone, Michelin, and BFGoodrich. Brand coverage changes by size, so a shopper should not expect every brand to appear in every 1904 fitment. Some smaller applications have a narrower product set, while certain larger or more established sizes offer a broader selection of period-oriented products.

Universal Vintage Tire appears in multiple sizes, including 28X3, 30X3, 30X3.5, and 34X4. Coker Classic products are available in 30X3, Firestone appears in 30X3.5 and 34X4, and Michelin and BFGoodrich are represented in 34X4. Brand choice is useful for narrowing the search, but size remains the first filter because each brand’s 1904 coverage is application-specific.

Sidewall styles for 1904 vehicle tires include Blackwall, All White, and Wide Whitewall, depending on the tire size. Blackwall is the most broadly represented treatment across the available products, while All White appears in smaller and mid-range sizes such as 28X3, 30X3, and 30X3.5. Wide Whitewall is represented in the larger 34X4 fitment.

These differences matter because sidewall style is part of the overall visual character of a Brass Era restoration. A 28X3 buyer can compare Blackwall and All White versions of the same Universal Ribbed Tread line, while a 34X4 buyer may choose between more than one brand and sidewall treatment. The important point is that sidewall appearance follows size-specific product availability, not a universal year-wide standard.

Yes. Modifications can affect tire fitment on a 1904 vehicle, especially because these Brass Era applications already use specialized sizing and early wheel systems. Changes to wheels, hubs, suspension components, steering geometry, bodywork, or axle setup can alter clearance and may affect whether the intended tire size still works as expected on the vehicle.

This matters even more on restored collector vehicles, since a surviving 1904 car may not retain its original configuration. A vehicle listed for 30X3.5 or 34X4 should still have its wheel diameter and overall space checked before installation. If a current tire or wheel setup differs from the vehicle’s historical specification, fitment should be verified carefully rather than assuming the year and model alone settle the issue.

Before installing tires on a 1904 vehicle, confirm the exact size required for the make and model, inspect the wheels, and compare any listed rim dimensions to the product you are considering. It is also wise to check for signs of previous modifications, including replacement wheels or changes to suspension and steering parts that could affect clearance or seating.

Where specifications are listed, they can help guide the match. For example, 30X3.5 products are shown on 23-inch rims, 30X3 on 24-inch rims, and 34X4 on 26-inch rims. Some products also include load information, such as 800 pounds at 65 psi or 1102 pounds at 60 psi. Those details are useful reference points, but the final installation decision should still be based on the vehicle’s actual configuration.

Tires on a 1904 vehicle should be inspected regularly for aging, cracking, tread wear, sidewall condition, and proper inflation. Because these are early Bias Ply applications used on collector vehicles, maintenance is often as much about preservation as it is about mileage. Wheels and mounting surfaces should also be checked, especially on clincher-oriented or other period-style setups where correct seating is essential.

Ongoing care should match how the vehicle is used and stored. A Brass Era car that sees parade, touring, or show duty may spend long periods parked, so tire pressure and storage conditions matter. Keeping the vehicle out of prolonged sun exposure and checking inflation before road use can help protect both ride quality and tire life. Inspection is especially important when the vehicle is infrequently driven.
