The 1909 Buick Model G comes from the brass-era period when tire choice was tied closely to the car’s mechanical character and its tall, narrow wheel-and-tire package. Owners restoring or maintaining one of these early Buicks are usually balancing authenticity of appearance with the practical need for safe, usable road manners at modest speeds. The 1909 Buick Model G uses a 30X3.5 bias-ply tire in an antique inch beaded-edge style. Within that size, there is still meaningful choice in tread style, sidewall presentation, and brand, including blackwall, all white, and all gray offerings. Getting the right look starts with the correct 30X3.5 fitment and careful confirmation of wheel type before installation.
Which Tire Size Is Right for The 1909 Buick Model G
The 1909 Buick Model G uses one primary tire size: 30X3.5. This is a bias-ply antique inch beaded-edge fitment used on a 23-inch rim, and the same size applies to the covered Standard sub-model. Once the size is confirmed, the real choice becomes selecting the right tread style, sidewall appearance, and restoration-oriented presentation for how the car will be shown, driven, and maintained.
In a 30X3.5 size, the first number refers to the tire’s approximate outside diameter, while the second refers to its nominal section width in inches rather than the wheel diameter. For the 1909 Buick Model G, this is a brass-era bias-ply beaded-edge style fitment that belongs to the narrow, tall tire profile common to the period. Available choices include offerings from Firestone, Universal Vintage Tire, Excelsior, and Coker Classic, with blackwall, all white, and all gray sidewall treatments across several tread styles and series. Choosing within 30X3.5 is less about changing size and more about matching wheel type, appearance goals, and intended road use.
Fitment is straightforward for the covered 1909 Buick Model G sub-models because the same primary tire size is used throughout. Checking the exact sub-model still helps confirm that the car remains on the expected brass-era wheel and tire setup before choosing among available tread and sidewall options.

1909 Buick Model G Standard
The 1909 Buick Model G Standard uses the same 30X3.5 bias-ply fitment as the core Model G application. That keeps tire selection focused on beaded-edge compatibility, period-style appearance, and the choice between blackwall, white, gray, smooth, ribbed, or non-skid style offerings.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1909 Buick Model G?
The 1909 Buick Model G uses a 30X3.5 tire. This is a bias-ply antique inch fitment in a beaded-edge or clincher-style presentation, and it is the primary size used for the covered Model G application, including the Standard sub-model.
With an early car like this, confirming the wheel setup matters as much as confirming the tire size itself. A 30X3.5 brass-era tire should be matched to the correct style wheel, and many buyers also compare tread style and sidewall finish so the final choice suits both restoration appearance and light road use.
What size rim does a 1909 Buick Model G use?
The available 30X3.5 tires for the 1909 Buick Model G are built for a 23-inch rim. That is typical of antique diameter-by-section sizing, where the tire size code reflects overall tire diameter and section width rather than naming the wheel diameter directly.
That distinction is important because a 30X3.5 tire is not for a 30-inch wheel. Before mounting tires, confirm the wheel is the correct 23-inch brass-era type and inspect its condition carefully, especially on a collector car that may have older rims, previous repairs, or replacement wheels from another early application.
Does the 1909 Buick Model G Standard use the same tire size?
Yes. The 1909 Buick Model G Standard uses the same 30X3.5 bias-ply tire size as the core 1909 Buick Model G fitment. That keeps size selection simple and lets the focus shift to period-style details such as tread design, sidewall color, and brand.
Even with shared fitment, it is still smart to verify that the car has the expected wheel type and has not been altered over the years. Early vehicles are often restored more than once, and wheel substitutions can affect whether a clincher or beaded-edge style tire is appropriate for the car now in front of you.
Choosing the Right Tire
What should I consider when choosing a 30X3.5 tire for a 1909 Buick Model G?
Start with the correct 30X3.5 size and confirm that the tire matches the Buick’s brass-era wheel style. From there, the main considerations are bias-ply construction, clincher or beaded-edge presentation where applicable, tread pattern, sidewall color, and whether the tire suits a restoration display car or one that will see occasional road use.
Product details can also help narrow the choice. Some 30X3.5 options emphasize a traditional blackwall look, while others offer all white or all gray sidewalls for a different presentation. Looking at rim compatibility, load information where stated, and made-to-order status can prevent choosing a tire that looks right but does not suit the wheel or project goals.
What sidewall styles are available for 1909 Buick Model G tires?
The 1909 Buick Model G’s 30X3.5 tire options include blackwall, all white, and all gray sidewall styles. Those appearance differences can change the finished look of the car significantly, even though the tire size and basic brass-era bias-ply character remain the same.
Sidewall choice should follow the look you want from the restoration rather than assumption alone. A blackwall often gives a more understated mechanical appearance, while all white or gray can create a brighter period-style presentation. Buyers concerned with exact historical accuracy should compare the tire choice against photos, marque references, and the car’s restoration objective.
What brands offer tires for the 1909 Buick Model G?
The 1909 Buick Model G’s 30X3.5 fitment is available from Firestone, Universal Vintage Tire, Excelsior, and Coker Classic. Those brands appear across several brass-era tire styles, including clincher-style, ribbed, smooth-tread, and restoration-oriented presentation choices.
Brand alone is only one part of the decision. It helps to compare each offering by sidewall style, tread character, wheel compatibility details, and whether the tire is aimed more at visual authenticity or general collector-car use. That approach usually produces a better result than choosing strictly by brand name on an early Buick application.
Restoration & Appearance
Which tire should I choose for a period-style 1909 Buick Model G?
A period-style 1909 Buick Model G tire choice starts with the correct 30X3.5 brass-era bias-ply fitment. From there, buyers usually compare clincher or beaded-edge style presentation, tread pattern, and sidewall finish to find a tire that suits the car’s restoration direction without moving away from the proper early-car proportions.
The right appearance depends on how closely the car is being restored and how it will be used. Some owners prefer a blackwall tire with a more mechanical look, while others want an all white or gray presentation. For exact originality, historical photos, Buick literature, and marque-club guidance are better references than appearance alone.
Does correct tire fitment matter for a 1909 Buick Model G restoration?
Yes, correct tire fitment matters a great deal on a 1909 Buick Model G because the tire is a visible part of the car’s brass-era stance and character. The 30X3.5 size, tall profile, and early wheel relationship all contribute to how authentic the finished car looks and how properly it sits.
Fitment is not only about appearance. Early wheel types require the right tire construction and mounting compatibility, and using the wrong style can create problems before the car even reaches the road. A restoration-minded buyer should confirm wheel condition, tire style, and overall presentation together rather than treating size as the only decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1909 Buick Model G?
Yes. Even though the 1909 Buick Model G uses a single 30X3.5 fitment, changes made over the car’s long life can affect what tire is appropriate today. Replacement wheels, altered hubs, brake work, or non-original restoration parts can all change whether a particular brass-era tire style matches the car correctly.
That is why early-car tire selection should start with an inspection of the actual wheel and mounting setup on the vehicle, not just the model name. Measuring the rim, checking its condition, and confirming there is no mismatch between tire style and wheel type will help avoid problems with mounting, clearance, and overall presentation.
What should I inspect before driving a 1909 Buick Model G on new tires?
Inspect the wheels first, especially the bead area, rim condition, and any signs of age, rust, distortion, or prior repair. Then check tire inflation, valve condition, and overall mounting quality so the 30X3.5 tires are seated properly and the car is ready for the modest road use expected of a brass-era Buick.
A broader pre-drive check also matters on a collector vehicle that may spend long periods parked. Look for steering play, suspension looseness, brake condition, and adequate clearance as the front wheels turn lock to lock. On an early Buick, the tire is only one part of safe operation, so the whole running gear deserves attention.
How should 30X3.5 tires on a collector 1909 Buick Model G be maintained?
Collector-car tires in 30X3.5 size should be kept properly inflated, visually inspected often, and protected from long exposure to sunlight, moisture, and ozone sources. Because early cars are driven infrequently, aging and storage conditions can matter just as much as tread wear on a 1909 Buick Model G.
Regular checks should include sidewall cracking, cuts, bulges, air loss, and any sign that the tire or wheel has shifted since installation. It also helps to move the car periodically and store it on a clean, dry surface. A brass-era tire can look serviceable at a glance, so close inspection is part of responsible ownership.
