1906 Studebaker came from a company in transition, carrying its wagon-building heritage into the Brass Era with practical, prestige-minded automobiles that still reflected early motoring's rapid experimentation. In that period, Studebaker's lineup could differ meaningfully from one model to the next, even when the cars shared the same overall vintage character. For 1906 Studebaker, three models use three distinct antique tire sizes, with Model E split between two fitments while Models F and G share a larger common size. The first step is to confirm your exact model and then match the correct antique tire size and wheel diameter before narrowing your choice by sidewall style and restoration goals.
Which Tire Size Is Right for Your 1906 Studebaker
Three tire sizes are available for 1906 Studebaker vehicles, and they vary by model rather than being shared across the full range. The key decision is confirming the correct model and wheel diameter first, because these antique sizes do not all mount on the same rim diameter. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 1906|Fit(s): Model E|Construction: Bias Ply|Rim: 24 in
32X4 is an antique diameter-by-section size in which 32 refers to the tire's overall outside diameter and 4 refers to its nominal section width, and it is a bias-ply fitment for a 24-inch rim. Brands in this size include BFGoodrich, Firestone, and Lester, with blackwall and all-white sidewall styles available. This size is specific to the 1906 Studebaker Model E rather than universal across the year and make. It suits a buyer restoring a Brass Era Model E who wants an era-appropriate bias-ply tire with a choice of traditional blackwall or brighter period-style white sidewall presentation.
Year(s): 1906|Fit(s): Model E|Construction: Bias Ply|Rim: 23 in
32X4.5 is an antique diameter-by-section size, with a 32-inch overall diameter and a 4.5-inch nominal section width, built here as a bias-ply tire for a 23-inch rim. BFGoodrich and Firestone offer this size, with blackwall, all-white, and wide whitewall sidewall styles available, and load-capacity markings appear on some products at 65 psi. This size is also specific to the 1906 Studebaker Model E and is not shared with Models F or G. It is the right direction for a Model E owner who has confirmed the smaller 23-inch wheel and wants a period-correct antique tire with more sidewall-style variety.
Year(s): 1906|Fit(s): Model F, Model G|Construction: Bias Ply|Rim: 26 in
34X4 is an antique diameter-by-section size that denotes a 34-inch overall tire diameter and a 4-inch nominal section width, constructed as a bias-ply tire for a 26-inch rim. Brands in this size include Michelin, BFGoodrich, Firestone, and Universal Vintage Tire, with blackwall and wide whitewall sidewall styles available; some products also carry load-capacity markings at 60 psi. This size is specific to the 1906 Studebaker Model F and Model G rather than the full lineup. It fits buyers preserving the taller Brass Era look of those models and choosing among period-style bias-ply offerings by brand character and sidewall appearance.
Three 1906 Studebaker models are covered here. Tire size varies by model, and Model E itself spans two different antique fitments, so identifying your exact model is more important than knowing only the year and make. Select a model below to narrow your fitment history and see the tires that apply to that specific Studebaker.
1906 Studebaker Model E
The 1906 Studebaker Model E reflects the experimental, coachbuilt character of Brass Era motoring, when body style and mechanical layout often produced meaningful differences in tire fitment. This model uses either a 24-inch-rim 32X4 or a 23-inch-rim 32X4.5, so wheel confirmation matters before moving on to sidewall style or brand preference.
The 1906 Studebaker Model F sits firmly in the early automobile era, when Studebaker was building upscale, carriage-influenced machines for buyers stepping into motoring's formative years. Its tires mount on 26-inch rims and use the larger 34X4 antique size shared with the Model G.
The 1906 Studebaker Model G belongs to the same Brass Era family of early Studebaker automobiles, with the upright proportions and formal appearance collectors expect from the period. It also uses the 34X4 antique tire on a 26-inch rim, making it a shared fitment with the Model F rather than the Model E.
Fourteen products are available across three tire sizes for 1906 Studebaker vehicles: four in 32X4 from BFGoodrich, Firestone, and Lester in bias-ply blackwall and all-white styles; four in 32X4.5 from BFGoodrich and Firestone in bias-ply blackwall, all-white, and wide whitewall styles; and four in 34X4 from Michelin, BFGoodrich, Firestone, and Universal Vintage Tire in bias-ply blackwall and wide whitewall styles. Confirm your model, size, and preferred sidewall appearance before selecting.
These FAQs sort out the model-by-model size differences found across 1906 Studebaker vehicles, explain what antique tire codes mean, and cover the setup, preservation, and road-use questions that matter with Brass Era automobiles.
Size Basics & Fitment
What tire sizes fit 1906 Studebaker vehicles?
1906 Studebaker vehicles use three antique tire sizes: 32X4, 32X4.5, and 34X4. Model E uses either 32X4 or 32X4.5, while Models F and G use 34X4. Those sizes do not share one wheel diameter across the lineup, because 32X4 mounts on a 24-inch rim, 32X4.5 mounts on a 23-inch rim, and 34X4 mounts on a 26-inch rim.
That means year and make alone are not enough to choose tires for a 1906 Studebaker. Start by identifying whether you have a Model E, F, or G, then confirm the actual wheel diameter on the car before selecting a tire. Once the size is settled, the remaining choice usually comes down to sidewall appearance and brand preference within the correct antique bias-ply fitment.
What does 32X4 mean on a 1906 Studebaker tire?
On a 1906 Studebaker, 32X4 is an antique diameter-by-section size rather than a modern inch or metric code. The first number, 32, identifies the tire's overall outside diameter in inches, and the second number, 4, identifies its nominal section width. In the currently available fitment range for 1906 Studebaker, 32X4 is a bias-ply tire that mounts on a 24-inch rim.
That code matters because antique tires are often understood very differently from later numeric or metric sizes. A buyer restoring a Model E should not assume that another 32-inch tire is interchangeable if its section width or wheel diameter changes. Matching the exact 32X4 size keeps you aligned with the proper rim diameter and the tall, narrow Brass Era proportions expected on an early Studebaker.
Do all 1906 Studebaker models use the same tire size?
No, 1906 Studebaker models do not all use the same tire size. Model E uses 32X4 or 32X4.5, while Models F and G share 34X4. The difference is not just sidewall style or brand availability; it also includes different wheel diameters across the model range.
That distinction is especially important on Brass Era vehicles, where surviving cars may have been restored more than once and wheel changes can happen over time. If your car is a Model E, confirm whether it wears the 23-inch-rim 32X4.5 setup or the 24-inch-rim 32X4 setup. If your car is a Model F or Model G, focus on the 34X4 fitment and then narrow your choice by sidewall look.
Buying the Right Tire
What sidewall styles are available for 1906 Studebaker tires?
1906 Studebaker tires are available in several period-style sidewall treatments depending on size. The 32X4 size comes in blackwall and all-white versions. The 32X4.5 size offers blackwall, all-white, and wide whitewall choices. The 34X4 size is available in blackwall and wide whitewall styles.
For a Brass Era Studebaker, sidewall style affects the finished look almost as much as the tire size itself. Blackwall usually gives the most restrained, mechanical appearance, while all-white or wide whitewall options create a brighter, more formal presentation that many early-car collectors prefer. If authenticity is a priority, compare your choice against period photos, surviving original cars, and the standards used by the marque group or event where the car will be shown.
What brands make tires for 1906 Studebaker vehicles?
Several brands cover 1906 Studebaker fitments. The 32X4 size is available from BFGoodrich, Firestone, and Lester. The 32X4.5 size is available from BFGoodrich and Firestone. The 34X4 size is available from Michelin, BFGoodrich, Firestone, and Universal Vintage Tire. All of the available 1906 Studebaker fitments are bias-ply tires built in antique sizes.
Brand choice on a Brass Era car is often about presentation, series character, and the specific sidewall style offered in the correct size. Some owners prioritize a familiar heritage name, while others simply want the right dimensions and a sidewall treatment that suits the car's period look. Once your size is confirmed, compare brands within that fitment rather than trying to cross-shop across sizes meant for different Studebaker models.
What is the difference between BFGoodrich and Firestone options for 1906 Studebaker Model E tires?
For 1906 Studebaker Model E tires, both BFGoodrich and Firestone cover the 32X4 and 32X4.5 antique sizes, but their available appearances differ by size. In 32X4, BFGoodrich appears in blackwall form, while Firestone offers both blackwall and all-white versions. In 32X4.5, BFGoodrich appears in blackwall and wide whitewall form, while Firestone offers blackwall and all-white versions. Load markings are also shown on some products in both brands, with 32X4 listed at 60 psi and 32X4.5 listed at 65 psi on certain offerings.
That means the practical comparison is often visual and application-specific rather than a question of one brand fitting better than the other. If your Model E restoration calls for a brighter sidewall treatment, your preferred look may point you toward one brand's offering in a given size. Narrow the decision by confirming your wheel diameter first, then comparing the available sidewall style within the correct 32X4 or 32X4.5 fitment.
Fitting & Setup
What rim width do 1906 Studebaker tires require?
1906 Studebaker fitments are tied clearly to rim diameter, with 32X4 on 24-inch rims, 32X4.5 on 23-inch rims, and 34X4 on 26-inch rims. Those diameter matches are essential for correct fitment on antique clincher-style era wheels. The available fitment range here centers on choosing the proper size-to-rim-diameter combination for the specific model rather than mixing among interchangeable wheel sizes.
Before committing to a tire, inspect the wheels currently on your Studebaker and confirm they match the size used by your model. Brass Era cars can accumulate replacement wheels or mixed parts during long restoration histories, so a visual check matters. If there is any doubt, compare your wheel dimensions with a knowledgeable early-car specialist before selecting among 32X4, 32X4.5, or 34X4.
Do 1906 Studebaker tires require inner tubes?
The available 1906 Studebaker tires are all antique bias-ply fitments, a category commonly associated with tube-type service on early wheels. These sizes are 32X4, 32X4.5, and 34X4, all built for Brass Era applications rather than modern tubeless wheel systems. Early Studebaker wheel construction is the larger reason tube use remains part of the setup conversation on a car of this age.
Inner-tube requirements should be confirmed against the exact wheel and the specific tire you choose, especially on a car that may have had wheel work or restoration changes over the last century. A buyer should treat tube selection, flap requirements if applicable, and valve-stem compatibility as part of the tire package rather than as an afterthought. That extra verification is worthwhile on any 1906 Studebaker before final installation.
Maintenance, Storage & Longevity
How should I store a 1906 Studebaker when the tires are fitted?
A 1906 Studebaker should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that accelerate sidewall aging. Keep the tires clean, maintain appropriate inflation for storage, and avoid letting the car sit in standing moisture. Because these are antique bias-ply tires, long static periods can also encourage temporary flat-spotting and uneven stress on the carcass.
If the car will sit for an extended season, roll it periodically or support it in a way that reduces constant load on one contact patch, while following sound storage practice for the chassis as a whole. Collectors who preserve early Studebakers for tours and shows often find that careful storage habits protect appearance as much as service life. Good storage will not stop age entirely, but it does slow the cracking and hardening that shorten usable life.
How long do tires on a 1906 Studebaker typically last?
Tires on a 1906 Studebaker are best judged by age and condition rather than mileage alone. Collector tires often age out before they wear out, especially on low-use Brass Era cars that spend more time stored than driven. A practical rule is to begin closer evaluation around five to seven years of age and to treat the ten-year mark as a point for serious replacement consideration, regardless of tread depth.
Check the manufacturing date and inspect the tire regularly for sidewall cracking, hardening, bulges, separation, and other age-related changes. A lightly driven early Studebaker can still be riding on tires that look respectable from a few feet away but are no longer ideal for road use. If the car is toured at speed or carries passengers regularly, age-based replacement becomes even more important than visible wear.
How often should tires on a 1906 Studebaker be inspected?
Tires on a 1906 Studebaker should be inspected before every drive and again before any longer tour or event. Look closely for cracking at the sidewall and bead area, cuts, tread damage, irregular wear, and signs that the tire has lost pressure since the last outing. On a Brass Era car, the inspection should also include valve stems and any tube-related service items that are part of the wheel-and-tire assembly.
Regular checks matter because an early Studebaker may cover few miles, yet still spend long periods parked where age and storage conditions work against the tire. Short local drives can mask a slow loss of condition that becomes more serious on a longer outing. A pre-drive inspection takes only a few minutes and is one of the simplest ways to protect both the car and the people riding in it.
Restoration & Authenticity
What tires were originally fitted to the 1906 Studebaker Model E?
A 1906 Studebaker Model E belongs to the Brass Era, so bias-ply construction is the historically correct type for an original-style restoration. Within the fitments available today for that model, Model E uses either 32X4 or 32X4.5 depending on the wheel setup on the car. Both are antique diameter-by-section sizes appropriate to the period, but they mount on different rim diameters, so they are not interchangeable simply because the first number is the same.
For authenticity, confirm whether your Model E should be on the 24-inch-rim 32X4 or the 23-inch-rim 32X4.5 arrangement before choosing a tire. Early-car restorations can vary by surviving equipment, body style history, or prior restoration work, so marque clubs and experienced Brass Era specialists remain the best resource for market- and car-specific confirmation. Once the size is confirmed, select the sidewall style that best matches the era presentation you want.
Does correct tire fitment matter for showing a 1906 Studebaker?
Correct tire fitment matters on a 1906 Studebaker because show judging for early cars often pays close attention to overall stance, size, construction type, and sidewall appearance. A Brass Era Studebaker should present on the correct antique bias-ply size for the model, and the wrong wheel diameter or an obviously mismatched sidewall treatment can change the car's visual proportions quickly.
That does not mean every event uses identical standards, but it does mean tire choice is part of authenticity rather than a minor finishing detail. Buyers preparing a car for concours, AACA-style judging, or marque-focused events should confirm the correct model-specific fitment first, then compare blackwall, all-white, or wide whitewall options against the kind of presentation they are trying to achieve. Event rules and marque clubs are the best guides for final judging expectations.
What is the difference between blackwall and white-sidewall choices for 1906 Studebaker tires?
For 1906 Studebaker tires, the available appearance choices depend on size. The 32X4 size offers blackwall and all-white versions. The 32X4.5 size offers blackwall, all-white, and wide whitewall versions. The 34X4 size is available in blackwall and wide whitewall form. All remain period-style antique bias-ply tires, so the main difference is presentation rather than a shift to a different construction type.
A blackwall tire tends to give a more understated mechanical look, while all-white and wide whitewall styles can make a Brass Era Studebaker appear more formal and visually prominent. On an early automobile, that visual change is substantial because the tire is such a large part of the car's silhouette. If originality matters, compare your choice with period photographs and the standards favored by the clubs or judges most relevant to your restoration goals.
Safety & Road Use
Are 1906 Studebaker tires safe for highway driving?
1906 Studebaker tires are antique bias-ply designs intended for Brass Era vehicles, so safe road use depends on more than the tire alone. The currently available sizes here do not show modern speed-rating markings, and these cars come from an era whose braking, steering, suspension, and road manners were designed long before modern highway expectations. In practical use, the vehicle's own age and engineering limits are usually the larger concern than chasing a tire speed threshold.
That does not rule out road driving, but it does call for conservative operation and a realistic understanding of what a 1906 automobile is meant to do. A buyer planning tours or event use should focus on tire age, condition, pressure, and correct fitment, then match driving speed to the car's mechanical capability and the road environment. Early Studebakers are best enjoyed within the limits of the period, not treated like modern traffic appliances.
What inflation pressure should I use for 1906 Studebaker tires?
Available 1906 Studebaker tire listings show load-and-pressure markings on some products, and those figures vary by size. In 32X4, marked examples show 1000@60 psi and 1051@60 psi. In 32X4.5, marked examples show 1250@65 psi and 1353@65 psi. In 34X4, at least one marked example shows 1102@60 psi. Those are tire ratings, not a blanket inflation instruction for every car and use condition.
Use the car's original factory guidance where available as the starting point, then confirm that your chosen reproduction tire's pressure limits are appropriate for the way the car is equipped and driven. Do not transfer a pressure figure from 32X4 to 32X4.5 or 34X4 just because the numbers seem close. On a 1906 Studebaker, correct pressure should always follow the exact tire size and the specific product fitted to the wheel.
What should I check before taking a 1906 Studebaker on a longer drive?
Before a longer drive in a 1906 Studebaker, inspect each tire for cracking, cuts, bulges, tread damage, uneven wear, and steady air retention, then confirm that the spare is also serviceable. Pay close attention to valve stems and any tube-related service items that belong with the tire and wheel assembly. A century-old car also deserves a broader mechanical check that includes brakes, steering, wheel bearings, and other period systems that matter just as much as the tires.
The point is to think of the tires as one part of the whole touring system rather than an isolated component. Brass Era cars can feel fine on short local drives yet reveal weaknesses once speeds rise slightly or distances grow. A careful pre-drive routine helps you catch aging tires, underinflation, or wheel-related issues before they turn into roadside problems, and it makes longer outings in a 1906 Studebaker much more enjoyable.
