1907 Buick was part of the American brass-era boom, when the company was building light touring and runabout automobiles that helped establish Buick as a serious early-market name. These cars came from a period when tire sizing was still tied closely to overall tire diameter and section width, so understanding the code matters as much as knowing the model name. Across the four 1907 Buick models covered here, two antique-format bias-ply sizes were used, with Model D and Model S sharing one size and Model F and Model G sharing another. Before choosing a tire for a 1907 Buick, confirm the exact model first, then match the correct antique size and wheel diameter.
Which Tire Size Is Right for Your 1907 Buick
Two tire sizes are used across 1907 Buick vehicles, and they vary by model rather than being shared across the full range. The real decision starts with confirming whether your car uses the 23-inch or 24-inch wheel, since these antique bias-ply sizes do not share the same rim diameter. Sorting that out first makes it much easier to choose the right product and avoid a mismatch.
Year(s): 1907|Fit(s): Model D, Model S|Construction: Bias Ply|Rim: 24 in
32X4 is an antique size that uses overall tire diameter and nominal section width in inches, so it refers to a bias-ply tire roughly 32 inches tall and 4 inches wide on a 24-inch rim. Brands offered in this size include BFGoodrich, Firestone, and Lester, with blackwall and all-white sidewall styles available; load ratings shown in this size reach 1000 pounds at 60 psi and 1051 pounds at 60 psi, depending on product. This size is specific to 1907 Buick Model D and Model S rather than the full Buick range for the year. It suits buyers focused on brass-era fitment and appearance for the larger 1907 Buick models that used this wheel diameter.
Year(s): 1907|Fit(s): Model F, Model G|Construction: Bias Ply|Rim: 23 in
30X3.5 is an antique size that identifies overall tire diameter and nominal section width in inches, meaning a bias-ply tire about 30 inches tall and 3.5 inches wide on a 23-inch rim. Brands available here include Universal Vintage Tire and Firestone, with blackwall and all-white sidewall styles offered; load-rated products in this size are listed at 800 pounds at 65 psi. This size is specific to 1907 Buick Model F and Model G, so it is not interchangeable with the larger-size Buick models from the same year. It is the correct starting point for owners restoring or maintaining the smaller 1907 Buick cars built around this narrower antique tire format.
Four Buick models are covered for 1907, and tire size changes by model rather than carrying across the whole lineup. That means year and make alone are not enough here; identifying whether you have a Model D, F, G, or S determines both the tire size and the wheel diameter. Select a model below to narrow your fitment history and see the products that apply to that specific 1907 Buick.
1907 Buick Model D
The 1907 Buick Model D belongs to the larger end of Buick's early lineup, from a period when the company was building substantial brass-era touring cars with upright proportions and tall wheels. Its tires mount on 24-inch rims, which places it with the larger of the two 1907 Buick fitments shown here.
The 1907 Buick Model F was one of Buick's lighter and more compact early cars, representative of the practical runabout style that helped broaden motoring in the brass era. Its tires mount on 23-inch rims, separating it from Buick's larger 1907 models.
The 1907 Buick Model G shares the same early Buick character of high ground clearance, narrow tires, and distinctly prewar proportions, aimed at motorists who wanted a light touring-style car. It also uses 23-inch rims, matching the smaller antique tire size offered for 1907 Buick applications.
The 1907 Buick Model S sits with Buick's larger brass-era offerings, where wheel diameter and tire stature were part of the car's visual presence as much as its road manners. Its tires mount on 24-inch rims, aligning it with the same larger antique size used by the Model D.
Sixteen products are available across two tire sizes for 1907 Buick vehicles. The 32X4 size includes four bias-ply options from BFGoodrich, Firestone, and Lester in blackwall and all-white styles, while 30X3.5 includes four bias-ply options from Universal Vintage Tire and Firestone in blackwall and all-white styles.
These FAQs cover how 1907 Buick tire sizing changes by model, what early antique size codes like 32X4 and 30X3.5 actually mean, and what to check for brass-era driving, restoration accuracy, storage, and road use.
Size Basics & Fitment
What tire sizes fit 1907 Buick vehicles?
1907 Buick vehicles use two tire sizes: 32X4 and 30X3.5. The 32X4 size fits the 1907 Buick Model D and Model S and mounts on a 24-inch rim, while the 30X3.5 size fits the 1907 Buick Model F and Model G and mounts on a 23-inch rim. Rim width information appears within the 30X3.5 offerings at 2.025 inches on one Firestone clincher product.
That split means year and make are only the starting point for 1907 Buick fitment. Owners should identify the model first, then confirm the wheel diameter already on the car before choosing among available tires. On a brass-era automobile, those basics matter more than modern-style sizing assumptions because the two Buick fitments are different in both overall size code and rim diameter.
What does 32X4 mean on a 1907 Buick tire?
On a 1907 Buick, 32X4 is an antique diameter-by-section size. The first number refers to the tire's overall diameter in inches, and the second number refers to its nominal section width in inches. In this case, it is a bias-ply tire roughly 32 inches tall and 4 inches wide that mounts on a 24-inch wheel for the Buick Model D and Model S.
That sizing language comes from an era before later numeric, alphanumeric, and metric systems became standard. A buyer working with a 1907 Buick should read 32X4 as a period size description, not as a modern low-profile or wheel-width code. Matching the antique size and the 24-inch wheel correctly is what keeps the larger Buick models in the right fitment range.
What does 30X3.5 mean on a 1907 Buick tire?
On a 1907 Buick, 30X3.5 is also an antique diameter-by-section size. The 30 identifies the overall tire diameter in inches, and the 3.5 identifies the nominal section width in inches. For 1907 Buick applications, this is a bias-ply tire used on the Model F and Model G, and it fits a 23-inch rim.
That makes 30X3.5 a different fitment family from the larger 32X4 size used elsewhere in the 1907 Buick range. Owners should not treat the two as interchangeable just because both belong to the same year and make. On early cars like these, the antique code is the quickest way to sort out whether you are dealing with the smaller 23-inch-wheel Buick models or the larger 24-inch-wheel models.
Do all 1907 Buick models use the same tire size?
No, 1907 Buick models do not all use the same tire size. The Model D and Model S use 32X4 tires on 24-inch rims, while the Model F and Model G use 30X3.5 tires on 23-inch rims. That difference reflects the fact that Buick's 1907 lineup included cars of different physical scale within the brass-era market.
For a buyer, the practical takeaway is simple: confirm the model before focusing on brand or sidewall style. Once the model is identified, the correct antique size becomes much easier to narrow down. That is especially important on a 1907 Buick because even a small difference in antique sizing language represents a completely different wheel diameter and tire fitment.
Buying the Right Tire
What sidewall styles are available for 1907 Buick tires?
1907 Buick tires are available in both blackwall and all-white sidewall styles, depending on size and product line. The 32X4 size is offered in blackwall and all-white versions, and the 30X3.5 size is also available in blackwall and all-white versions. That gives owners of either 1907 Buick fitment a choice in presentation without changing the underlying antique size.
For a brass-era restoration, sidewall appearance can affect the overall look almost as much as the body and wheels. Some owners prefer blackwall for a restrained service look, while others choose all-white for a more formal period presentation. If show authenticity matters for your 1907 Buick, compare the sidewall style on the car to period photos, restoration references, and marque-specific judging expectations before settling on a final look.
What brands make tires for 1907 Buick vehicles?
Several brands cover 1907 Buick fitments, but the brand mix depends on size. In 32X4, available brands include BFGoodrich, Firestone, and Lester. In 30X3.5, available brands include Universal Vintage Tire and Firestone. All of the offerings for these 1907 Buick sizes are bias-ply tires suited to brass-era applications.
That means the brand decision usually comes after the fitment decision, not before it. Owners of a Model D or Model S will be choosing from one group of brands, while Model F and Model G owners will be choosing from another. Comparing brand availability by size can also help narrow the look you want, since sidewall presentation differs across the available 1907 Buick products.
What is the difference between Firestone and Universal Vintage Tire options for 1907 Buick 30X3.5 tires?
For 1907 Buick 30X3.5 applications, Universal Vintage Tire offers blackwall and all-white versions in its T-Driver and Ribbed Tread lines, while Firestone offers clincher-style blackwall options in the same size. Firestone's 30X3.5 products list a maximum load of 800 pounds at 65 psi, and one Firestone clincher version specifies a 2.025-inch rim width. The listed weights in this size are 15 pounds across the available products shown here.
The choice comes down less to basic fitment and more to visual character and the type of restoration you are pursuing. A clincher-oriented product may appeal to owners trying to match an early hardware style, while another owner may prioritize a different tread or sidewall presentation. On a 1907 Buick, the smartest approach is to confirm the wheel type and then compare the appearance details that best suit the car's intended finish.
Fitting & Setup
What rim width do 1907 Buick tires require?
Rim width guidance within the available 1907 Buick products appears in the 30X3.5 size, where one Firestone clincher tire is listed for a 2.025-inch rim width. The 30X3.5 size mounts on a 23-inch rim, while the 32X4 size mounts on a 24-inch rim. Those rim diameters are fixed by size and model, even though width details are not equally detailed across every product line.
Before fitting tires to a 1907 Buick, measure the actual wheel and confirm the wheel type as well as the diameter. Early cars can retain original hardware, period replacements, or later service parts, and those differences matter. If your Buick is being restored rather than simply maintained, checking the wheel against a marque specialist or an experienced brass-era shop can prevent expensive mistakes.
Do 1907 Buick tires require inner tubes?
The available 1907 Buick tire listings are brass-era bias-ply products, including clincher and early high-pressure styles, but they do not carry tubeless markings. On automobiles from 1907, inner tubes are typically part of the overall tire and wheel setup because the wheel and tire designs predate later tubeless practice. That expectation is especially relevant on antique Buick applications using 30X3.5 and 32X4 sizes.
Owners should confirm the exact tube and flap requirements against the wheel design already on the car before finalizing a setup. Brass-era wheels can differ in bead design and hardware details, and the correct tube arrangement depends on that combination as much as on the outer tire size. A careful pre-installation check is more useful here than assuming all early 1907 Buick wheels are configured the same way.
Maintenance, Storage & Longevity
How should I store a 1907 Buick when the tires are fitted?
A 1907 Buick should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber. Clean floors, stable temperature, and protection from standing moisture all help preserve brass-era bias-ply tires. Because bias-ply construction can flat-spot more readily during long static periods, occasional repositioning or use of stands can be helpful.
Storage habits matter on a 1907 Buick because these cars are usually driven infrequently and spend long stretches at rest. Keeping the tires properly inflated during storage and moving the car slightly from time to time reduces stress on one contact patch. If the car is displayed for long periods, make tire condition part of the regular preservation routine rather than treating the tires as passive cosmetic pieces.
How long do tires on a 1907 Buick typically last?
Tire life on a 1907 Buick is usually better judged by age and condition than by mileage. Collector-car tires often age out before they wear out, so a useful rule is to begin careful evaluation around five to seven years and to consider replacement as the tire approaches ten years, depending on storage, use, and visible condition. The DOT date-code habit from modern service remains a good maintenance discipline even on low-use collector tires.
A brass-era Buick may cover only modest annual mileage, but age cracking, casing stiffness, and long storage periods still affect safety and drivability. Owners should look beyond tread depth and assess sidewalls, bead areas, and any signs of drying or separation. If a 1907 Buick is driven regularly on tours rather than only shown, aging concerns deserve even more attention than the odometer does.
How often should tires on a 1907 Buick be inspected?
Tires on a 1907 Buick should be inspected before every drive and again before any extended outing. Look for sidewall cracking, cuts, irregular wear, exposed fabric, bulges, low pressure, and signs that a valve stem or tube-related component may be losing air. On antique bias-ply tires, a careful visual and hand inspection is especially important because the car may spend long periods parked between uses.
A short local drive and a longer brass-era tour place very different demands on the same set of tires. Before any event or countryside drive, inspect the spare along with the four road tires so you are not depending on an aged backup. That routine gives a 1907 Buick owner a much better chance of catching age-related problems before they interrupt the outing.
Restoration & Authenticity
What tires were originally fitted to the 1907 Buick Model D?
A 1907 Buick Model D would have been equipped in the bias-ply era, and the size used here is 32X4. That matches the brass-era construction and antique sizing system expected for a car of this period. Original-equipment branding could vary by market, dealer, and service history, so the safest historically grounded starting point is the correct size, the correct period construction, and the correct wheel diameter.
For restoration work, that means treating 32X4 bias-ply fitment as the baseline and then refining the sidewall and brand presentation to suit your goals. If you are preparing a 1907 Buick Model D for judged display, period photos, factory literature, and Buick club references are the right way to confirm finer points. Getting the construction and size right first usually matters more than chasing an assumed original brand.
Does correct tire fitment matter for showing a 1907 Buick?
Correct tire fitment matters a great deal when showing a 1907 Buick because judges and knowledgeable enthusiasts notice size, construction type, wheel compatibility, and sidewall presentation immediately. On a brass-era car, an incorrect antique size or the wrong overall visual proportion can stand out as quickly as a non-period lamp or body detail. The fact that 1907 Buick models used different tire sizes by model makes that scrutiny even more important.
A Model D or Model S wearing 30X3.5 tires, or a Model F or Model G wearing 32X4 tires, would look wrong before anyone even checks finer authenticity details. Sidewall style can also influence how period-correct the finished car appears. If your 1907 Buick is headed for formal judging, compare your final tire choice against event rules and Buick marque guidance rather than relying only on general restoration practice.
What is the difference between BFGoodrich Silvertown Cord and Firestone High Pressure 32X4 tires for the 1907 Buick?
For 1907 Buick Model D and Model S applications in 32X4, the BFGoodrich Silvertown Cord is listed as a blackwall bias-ply tire with a maximum load of 1000 pounds at 60 psi and a listed weight of 31 pounds. Firestone High Pressure offerings in the same size appear in blackwall and all-white styles, with a maximum load of 1051 pounds at 60 psi; the blackwall version is listed at 31 pounds and the all-white version at 16 pounds.
That makes the comparison one of brand presentation, sidewall appearance, and specific listed load figures rather than basic fitment, since both are 32X4 bias-ply tires for the same 24-inch wheel size. Owners restoring a 1907 Buick can use those differences to fine-tune the look they want. A judged car may call for one visual style, while a touring car owner may simply want the product that best matches the wheel and intended use.
Safety & Road Use
Are 1907 Buick tires safe for highway driving?
1907 Buick tires are built for brass-era vehicles and should be used with the expectations appropriate to that type of automobile. The available 30X3.5 and 32X4 options shown here do not list modern passenger-car speed ratings, which is common for antique bias-ply tires. On a 1907 Buick, overall roadworthiness is shaped as much by early brakes, steering, suspension, and the car's original touring character as by the tire itself.
That usually means conservative speeds, smooth road selection, and realistic trip planning matter more than trying to treat a 1907 Buick like a later highway car. A well-maintained brass-era Buick can certainly be driven, but it should be driven within the limits of its design and the condition of its tires. Owners planning sustained road use should inspect the full chassis and wheel setup, not just the tread and sidewalls.
What inflation pressure should I use for 1907 Buick tires?
Inflation pressure on 1907 Buick tires should be matched to the exact size and product being used. Among the available tires here, 32X4 products list maximum load figures of 1000 pounds at 60 psi and 1051 pounds at 60 psi, while 30X3.5 Firestone products list 800 pounds at 65 psi. Those figures are product ratings, not a universal instruction to run every 1907 Buick tire at the same pressure.
The best practice is to start with the factory guidance for the car if available, then compare that to the reproduction tire's stated pressure and load limits. A 1907 Buick owner should avoid transferring one size's pressure habit to the other size, because the two fitments differ in both dimensions and wheel diameter. Pressure should support the car correctly without exceeding the tire's own rated limits.
What should I check before taking a 1907 Buick on a longer drive?
Before a longer drive in a 1907 Buick, inspect each tire for cracking, cuts, bulges, tread separation, uneven wear, and pressure loss. Check the valve stems and the condition of any tube-related hardware, and make sure the spare is serviceable as well. Since these are brass-era tires on brass-era wheels, wheel security and bead condition deserve close attention along with the usual rubber inspection.
A prudent owner also treats the tires as one part of a much broader pre-drive check. On a 1907 Buick, brakes, steering linkage, lubrication points, wheel bearings, and fuel-system reliability can be just as important to a successful outing as the tire condition itself. Looking at the whole car rather than only the tread helps match the preparation to the age and design of the automobile.
