1908 Buick Tire Fitment Guide

1908 Buick vehicles use four antique tire sizes across six models. The Model 10 uses 30X3 on 24-inch rims, the Model 5 uses 34X4 on 26-inch rims, the Model D and Model S use 32X4 on 24-inch rims, and the Model F and Model G use 30X3.5 on 23-inch rims. These are not interchangeable across the full 1908 Buick lineup because overall tire size and rim diameter both vary by model.

The practical takeaway is that year and make alone are not enough for a 1908 Buick tire search. Confirm the exact model first, then verify the wheel before choosing among available brands and sidewall styles. That matters especially on brass-era cars, where a difference of even one rim inch places the tire in a completely different fitment family.

On a 1908 Buick, 30X3 is an antique diameter-by-section size rather than a modern metric or alphanumeric code. The first number gives the approximate overall tire diameter in inches, so 30 means a 30-inch tire, and the second number gives the nominal section width, so 3 means about 3 inches wide. In current offerings for 1908 Buick applications, 30X3 is a bias-ply size mounted on a 24-inch rim.

That size belongs specifically to the 1908 Buick Model 10, so it should be treated as a model-specific fitment rather than a general Buick replacement. If you are working with a surviving car whose wheels or hubs have been changed over the past century, compare the actual rim before selecting a tire with the same period code.

No, 1908 Buick models do not all use the same tire size. Buick offered six models that year, and they spread across four antique sizes: 30X3, 34X4, 32X4, and 30X3.5. Only two pairings share sizes, with Model D and Model S both using 32X4, and Model F and Model G both using 30X3.5.

That means the first identification step is the model itself, not just the make. Once the model is known, the tire search becomes much narrower and you can focus on period appearance details like blackwall, all-white, or wide whitewall depending on what is offered in that size and the style direction of your restoration.

1908 Buick tire choices include several sidewall styles depending on size. The 30X3 size is offered in Blackwall and All White, 34X4 is available in Blackwall and Wide Whitewall, 32X4 comes in Blackwall and All White, and 30X3.5 also includes Blackwall and All White choices. All of these are bias-ply brass-era style tires, but the visual effect changes quite a bit from one sidewall treatment to another.

For a strict restoration, sidewall style should be chosen with the car's intended period presentation in mind, since brass-era judging often pays attention to both construction and appearance. If the goal is not formal show authenticity, the decision can be guided more by the look you prefer on the finished car, provided the size itself matches the correct model and rim.

Several brands cover 1908 Buick fitments, depending on size. Coker Classic and Universal Vintage Tire appear in 30X3, Michelin, BFGoodrich, Firestone, and Universal Vintage Tire appear in 34X4, BFGoodrich, Firestone, and Lester appear in 32X4, and Firestone plus Universal Vintage Tire appear in 30X3.5. All currently listed choices for these 1908 Buick sizes are bias-ply products intended for brass-era applications.

Brand choice on a 1908 Buick usually comes after the size and rim are confirmed, since each model narrows the field right away. Once you are within the correct size, compare the brands by their sidewall appearance, tread character, and any listed load information if your car sees regular event use or carries touring equipment.

For 1908 Buick applications in 30X3.5, Firestone Clincher and Universal T-Driver share the same basic size and both are bias-ply choices for 23-inch rims, but they are not identical products. Firestone Clincher examples in this size include listed load capacity of 800 pounds at 65 psi, and one version specifies a 2.025-inch rim width. Universal T-Driver is also offered in 30X3.5 with a blackwall presentation, but without the same published load and rim-width details on the examples available here.

That difference matters most when you are deciding how much technical specificity you want in the listing and what visual style best matches your Buick. Owners of a Model F or Model G should still start with the correct 30X3.5 size, then compare the individual product details to see which version aligns with the wheel and restoration approach they are working with.

One published rim-width figure appears within the 1908 Buick range: a 30X3.5 Firestone Clincher is specified for a 2.025-inch rim width. The tire families themselves mount on different rim diameters by model, with 30X3 and 32X4 on 24-inch rims, 34X4 on 26-inch rims, and 30X3.5 on 23-inch rims. No single rim width should be assumed across all 1908 Buick tires just because the cars come from the same year.

When setting up a brass-era Buick, the safest path is to match the tire to the actual wheel on the car instead of working from model name alone. Restored early cars sometimes carry replacement or swapped rims, and that can affect bead seating and overall stance even when the nominal tire code appears close.

The available 1908 Buick tire listings are antique and brass-era bias-ply designs, including clincher and beaded-edge style products, which places them firmly in the early-tire category rather than modern tubeless construction. No tubeless markings appear in these listed 1908 Buick sizes, and the products are presented in the kinds of constructions normally associated with tube-era fitments. That makes tube use an important setup consideration on these cars.

Before final assembly, confirm the requirements of the exact tire and wheel combination you plan to run, especially on original or older restored rims. On a brass-era Buick, tube condition, flap needs where applicable, and valve-stem sealing are just as important to a dependable setup as choosing the right outer tire size.

Original 1908 Buick wheels cannot be treated as universal across all four tire sizes because the lineup uses three different rim diameters: 23, 24, and 26 inches. A Model F or Model G uses a different rim family from a Model 10, and both differ again from the Model 5. Even where two sizes share a 24-inch rim diameter, such as 30X3 and 32X4, the tire dimensions themselves are still different.

That means wheel compatibility starts with the exact Buick model and the actual wheels currently fitted to the car. If the car has lived through multiple restorations, compare the rim's dimensions and construction style before assuming another antique Buick size will mount properly just because it came from the same manufacturer and year.

A 1908 Buick should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that age rubber. Brass-era bias-ply tires are especially prone to taking a temporary set when they sit in one position for long periods, and sidewalls can suffer from avoidable cracking if the car is left under load in poor conditions. Clean floors, stable temperature, and protection from moisture all help preserve the tire casing.

For longer storage, move the car periodically or use stands in a way that supports the vehicle safely without leaving the tires compressed for months at a time. Maintaining proper inflation during storage also helps, since an underinflated antique tire is more likely to distort and age unevenly before the Buick returns to the road.

On a 1908 Buick, tire life is usually judged more by age and condition than by mileage because most brass-era cars see limited annual use. A sound rule is to evaluate collector-car tires closely once they reach the five-to-seven-year range and to treat around ten years as a serious replacement consideration even if tread remains. The date code and the tire's physical condition matter more than how many parade or tour miles the car has covered.

That approach is especially important on a low-use 1908 Buick, where aging can happen long before the tread looks worn out. If the car has been stored indoors but rarely driven, the tires may still need replacement because of age hardening, sidewall checking, or internal deterioration that will not show up as obvious tread loss.

Tires on a 1908 Buick should be inspected before every drive and again before any longer tour or event. Look for sidewall cracking, cuts, weathering, bulges, loose cords, uneven tread wear, and signs that a tire is no longer holding pressure consistently. On an early tube-era setup, valve stems and any related tube hardware deserve the same attention as the outer casing.

Regular inspection matters because a brass-era car often sits far more than it drives, and storage-related aging can be easy to miss until the car is back on the road. A quick walkaround before each outing is usually enough to catch a problem early, and a more thorough inspection before a regional drive can prevent avoidable roadside trouble.

A 1908 Buick Model 10 would have been fitted with a period bias-ply tire in the 30X3 size family, which matches the brass-era construction used throughout the 1908 Buick range. That antique code belongs to the Model 10 specifically and mounts on a 24-inch rim in current reproduction offerings. Original-equipment branding could vary by market and period supply, so the key authenticity markers are the correct size family, construction type, and appropriate early sidewall presentation.

For restoration work, start by matching the Model 10's 30X3 fitment and then choose the sidewall treatment that best suits the car's restoration goal. If the Buick is being prepared for judged display, a marque club or event rulebook is the right place to confirm whether a particular white or black sidewall treatment is preferred for your exact body style and presentation standard.

Correct tire fitment matters a great deal when showing a 1908 Buick because brass-era judging often treats tires as an essential part of the car's overall authenticity. Size, construction, sidewall style, and general period appearance can all influence whether the finished car looks right for its year and model. A tire that belongs to another 1908 Buick model, even from the same make, can still appear visibly incorrect if its diameter, section width, or sidewall treatment is out of step.

For that reason, a show-focused restoration should begin with the proper model-specific size rather than with a broad year-and-make search. Event standards vary, so once the correct size is established, use club knowledge and judging references to decide whether blackwall, all-white, or wide whitewall styling best matches the way your 1908 Buick is meant to be presented.

In 32X4 fitments for 1908 Buick Model D and Model S cars, BFGoodrich Silvertown Cord and Firestone Non Skid are both bias-ply choices on 24-inch rims, but they differ in listed presentation and load details. BFGoodrich Silvertown Cord appears as a blackwall with a published load figure of 1000 pounds at 60 psi. Firestone Non Skid is offered in both blackwall and all-white versions, with a published load figure of 1051 pounds at 60 psi on the examples available here.

That gives a restorer two useful comparison points: visual style and the specific published specs attached to the product. For a 1908 Buick being prepared for events, the final decision often comes down to whether the preferred sidewall look is available in the right size and whether the tire's stated characteristics line up with the way the car will actually be displayed or driven.

1908 Buick tires in these applications are brass-era bias-ply designs, and no modern speed ratings are shown for the available sizes. That does not automatically make them unusable on public roads, but it does mean they should be treated like specialty collector-car tires on an early automobile whose brakes, suspension, steering, and general road manners belong to a much earlier period than modern traffic. Tire condition is only one part of the safety picture on a brass-era Buick.

A well-prepared 1908 Buick can be driven responsibly, but route choice, speed discipline, and mechanical condition matter just as much as the tires themselves. Before any highway use, make sure the entire car is sorted for sustained operation and avoid assuming that a sound reproduction tire alone makes an early touring car suitable for modern interstate-style travel.

Inflation pressure on a 1908 Buick depends on the exact tire size and the specific product being used. Published examples include 30X3 at 450 pounds maximum load at 65 psi, 30X3.5 at 800 pounds at 65 psi on certain products, 32X4 at 1000 pounds at 60 psi and 1051 pounds at 60 psi depending on product, and 34X4 at 1102 pounds at 60 psi on certain products. Those figures describe the tire's rated load-and-pressure pairing and should not be transferred from one size to another.

For actual running pressure, compare the tire maker's recommendations with the original Buick literature or a trusted brass-era specialist familiar with the model's weight and use. That matters because a reproduction tire's rated maximum pressure is not always the same thing as the most suitable operating pressure for ride quality, handling, and tread contact on an early car.

Before a longer drive in a 1908 Buick, inspect every tire for cracks, cuts, bulges, exposed fabric, irregular wear, and proper inflation, then check the spare with the same care. On a tube-era brass-era setup, valve stems and air retention deserve close attention because a tire can look acceptable from the outside and still have a problem in service. Wheel condition and secure mounting are equally important on an early car.

That tire inspection should be part of a broader pre-drive routine that also covers brakes, steering play, lubrication, cooling, and fuel delivery. A 1908 Buick rewards preparation, and longer outings are much more enjoyable when the car has been looked over as a complete mechanical system rather than treated like a modern car that can be driven after months of sitting.
