1936 Hupmobile Tire Fitment Guide

1936 Hupmobile vehicles use two different tire sizes depending on model. The Hupmobile G uses 600-16, while the Hupmobile OH uses 650-16. Both sizes mount on 16-inch wheels, but they are not interchangeable year-wide fitments because each one is tied to a specific model. For 600-16, listed rim widths run from 4.00 to 4.50 inches, and for 650-16, listed rim widths run from 4.50 to 5.00 inches.

That means the first step is identifying the model correctly, not simply the year and make. Once you know whether you have a 1936 Hupmobile G or OH, you can narrow the selection to the correct size and then compare blackwall versus wide whitewall versions, brand preference, and wheel-width compatibility. On a car that has changed hands many times, it is also wise to check the wheel itself before settling on a tire.

On a 1936 Hupmobile, 600-16 is a numeric bias-ply tire size. The 600 portion is the traditional nominal section-width code, and the 16 indicates the tire fits a 16-inch wheel. In the 1936 Hupmobile range, that size applies to the G model. Products in this size appear in period-style bias-ply construction, with blackwall and wide whitewall versions both available.

Modern buyers sometimes mistake a numeric vintage size for a direct modern metric equivalent, but that is not how these fitments should be approached. For a 1936 Hupmobile G, 600-16 should be treated as its own vintage specification, and the next checks are wheel width, sidewall appearance, and whether the car is being restored for authentic presentation or maintained as a road-going collector car.

No. The 1936 Hupmobile G uses 600-16, while the 1936 Hupmobile OH uses 650-16. Both are bias-ply 16-inch fitments, but the size split is model-specific. That distinction matters because the wheel-width ranges differ between the two sizes, and the visual proportion of the finished car changes with the correct tire.

If your car has been restored long ago or has replacement wheels, do not rely on memory or a prior invoice alone. Confirm the model designation and compare the tire size already on the car with the actual wheel dimensions. Once that is settled, you can focus on the appearance you want, such as blackwall for a plainer factory-style look or wide whitewall for a more upscale period presentation.

1936 Hupmobile tires are available in both blackwall and wide whitewall styles across the two fitment sizes. In 600-16, blackwall and wide whitewall choices appear from multiple brands, and the same is true in 650-16. That gives owners of either a 1936 Hupmobile G or a 1936 Hupmobile OH a choice between a simpler utilitarian appearance and a fuller prewar luxury-style presentation.

For a judged restoration, sidewall style should match the car's intended factory look, market position, and the way the specific car is being presented. Wide whitewalls often suit prewar American styling especially well, but blackwalls can also be appropriate depending on the vehicle and restoration goal. If authenticity matters at the event level, compare your choice against period photos and marque-club guidance before finalizing the tire.

Several brands offer tires for 1936 Hupmobile fitments. The 600-16 size includes BFGoodrich, Coker Classic, Avon, and Firestone, while the 650-16 size includes BFGoodrich, Coker Classic, Firestone, and Garfield. All listed options are bias-ply tires suited to the prewar character of 1936 Hupmobile applications, with brand choice mostly affecting sidewall style availability, construction details within the bias-ply category, and presentation.

Brand selection is usually easiest after the size is settled. Owners restoring a 1936 Hupmobile G may also notice an Avon offering in the 600-size family, while OH owners will see Garfield among the 650-16 options. Once you know the correct size for your model, compare the available sidewall appearance and rated specifications rather than assuming every brand offers the same visual or technical package.

For 1936 Hupmobile applications, BFGoodrich and Firestone both appear in bias-ply fitments, but the available versions differ by size and sidewall treatment. In 600-16, BFGoodrich is offered as a 3.50-inch whitewall with a 1400-pound capacity at 32 psi and a 4.00 to 4.50-inch rim-width range, while Firestone appears as a 3.25-inch whitewall with the same load and rim-width figures. In 650-16, BFGoodrich offers a 3.75-inch whitewall rated at 1580 pounds at 32 psi on 4.50 to 5.00-inch rims, while Firestone appears as a blackwall with the same load and rim-width figures.

The practical difference is largely visual in these examples rather than a dramatic fitment change. A 1936 Hupmobile owner choosing between BFGoodrich and Firestone should compare the exact whitewall width, sidewall appearance, and the model-specific size first. That is especially important on a prewar car, where the side profile of the tire contributes strongly to the finished stance and restoration style.

1936 Hupmobile rim-width requirements depend on the tire size. For 600-16, listed fitments call for rims from 4.00 to 4.50 inches wide. For 650-16, listed fitments call for rims from 4.50 to 5.00 inches wide. Both sizes use 16-inch rim diameter, but the width range changes with the model-specific tire size.

That makes rim measurement worth doing before you commit to a tire, especially on a car that may have had wheel swaps during its life. A 1936 Hupmobile G should be checked against the 600-16 width range, while a 1936 Hupmobile OH should be checked against the 650-16 range. Staying within the listed range helps preserve the intended profile, appearance, and steering feel of a vintage bias-ply tire.

Original 1936 Hupmobile wheels can share the same 16-inch tire diameter across the G and OH fitments, since both 600-16 and 650-16 mount on 16-inch rims. That does not automatically mean every 16-inch wheel is correct for both sizes, because the listed rim-width ranges differ. The 600-16 size uses a narrower 4.00 to 4.50-inch range, while the 650-16 size uses a 4.50 to 5.00-inch range.

If you are evaluating a set of loose original wheels or a car assembled from mixed parts, verify more than diameter alone. Measure wheel width and match it to the model-specific tire. That extra step is especially important with prewar cars, where small differences in wheel specification can affect how the tire seats, how the sidewall stands, and how authentic the finished setup looks.

A 1936 Hupmobile should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment that can accelerate sidewall aging. Because 1936 Hupmobile fitments here are bias-ply tires, long static periods can also encourage flat-spotting more readily than many later radial designs. Keeping the tires properly inflated and the car on a clean surface helps reduce strain during storage.

If the car will sit for months, roll it occasionally to change the contact patch, or use stands in a way that follows safe vehicle-support practices and avoids shock-loading aged suspension parts. A breathable cover and a stable indoor environment do more for tire longevity than frequent dressing products. Collector cars that are rarely driven often age their tires out long before they wear them out.

Tires on a 1936 Hupmobile are usually evaluated by age more than mileage. A sound rule for a collector vehicle is to begin paying close attention around the five- to seven-year mark and to treat about ten years as a strong point for replacement consideration, even if tread depth still looks good. The DOT date code on the tire is the starting point for determining actual age.

Prewar cars often see light seasonal use, which can make an older tire appear serviceable when the casing is already aging internally. If your 1936 Hupmobile has been in storage, recently purchased, or inherited, verify the tire age before planning road use. Small annual mileage does not cancel out the effects of time, heat cycles, and environmental exposure on an older bias-ply tire.

Tires on a 1936 Hupmobile should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, irregular wear, and pressure loss, and do not ignore a car that suddenly feels different in steering effort or ride. On a prewar vehicle, a brief walk-around before use is one of the simplest ways to catch a problem early.

For a collector car that may sit between drives, that inspection routine matters more than a calendar-based habit alone. Check the spare as well, since an old but unused spare can be in worse condition than the tires on the car. If the wheel and tire setup uses tubes, include valve-stem condition and air retention in your inspection rather than focusing on tread appearance alone.

A 1936 Hupmobile G belongs to an era when bias-ply construction was the standard original type, and the listed fitment for that model is 600-16. That makes a 600-16 bias-ply tire the right starting point for a historically faithful restoration. Blackwall and wide whitewall versions both exist in the modern reproduction market, but the correct appearance for an individual car can depend on how it was equipped and how you intend to present it.

If your goal is strict authenticity, use the size first and then verify the sidewall treatment against period literature, factory photos, or a Hupmobile marque specialist. Original-equipment branding should not be assumed from modern reproduction availability alone. For most restorers, getting the 1936 Hupmobile G onto the correct 600-16 bias-ply specification is the essential first step.

Correct tire fitment absolutely matters when showing a 1936 Hupmobile. Judges and knowledgeable enthusiasts often look at size, construction type, sidewall style, and overall visual proportion because tires strongly influence whether a prewar car looks properly finished. A model-specific mismatch such as using 650-16 where a 1936 Hupmobile G calls for 600-16 can stand out quickly, just as an obviously modern look can on a car presented for originality.

Even outside formal judging, the right tire changes stance and period character in a noticeable way. If the car will appear in marque-specific or concours settings, confirm standards with the relevant club or event before deciding between blackwall and whitewall presentation. The more authentic the restoration goal, the more important it becomes to match both the size and the visual style to the model.

For a 1936 Hupmobile, the main difference between blackwall and wide whitewall tires is visual presentation, not a change in basic era-correct construction. Both 600-16 and 650-16 are available in blackwall and wide whitewall forms, and all listed options remain bias-ply. Whitewall width can vary by product, as seen in examples such as 3.50-inch and 3.25-inch whitewalls in 600-16 and a 3.75-inch whitewall in 650-16.

That means the right choice depends on how you want the car to read visually and what is appropriate for the specific restoration target. Wide whitewalls can give a 1936 Hupmobile a richer, more formal prewar look, while blackwalls create a plainer and often more restrained appearance. When authenticity matters, compare the exact whitewall treatment to period references rather than choosing by broad era alone.

1936 Hupmobile tires can be suitable for highway use when they are the correct size, in sound condition, and matched to the way the car is driven. The listed fitments are bias-ply tires, and one 600-size offering appears as 600H16 with an H speed rating, which carries a 130 mph ceiling. Most real-world highway use in a 1936 Hupmobile will be governed more by the vehicle's age, braking capability, steering design, suspension condition, and overall mechanical health than by extreme tire speed capacity.

That practical difference matters because safe road use on a prewar car is about the whole system, not a single specification. Before a longer highway run, inspect the tires carefully, confirm inflation, and make sure the car tracks and stops properly. A well-sorted 1936 Hupmobile driven within its mechanical comfort zone is a very different proposition from assuming modern-car behavior simply because the tires are fresh.

Inflation pressure for 1936 Hupmobile tires should be guided first by the vehicle's factory recommendation and then checked against the rating on the specific reproduction tire you choose. Several 600-16 products list a maximum load of 1400 pounds at 32 psi, and several 650-16 products list a maximum load of 1580 pounds at 32 psi. Those figures are tire ratings, not universal instructions to run every 1936 Hupmobile tire at one exact pressure in all conditions.

Use the original owner's literature, service information, or a trusted Hupmobile specialist to establish the vehicle target, then confirm that your chosen tire's pressure and load rating support that use. Do not transfer a pressure approach from 600-16 directly to 650-16 or assume one brand's casing behaves exactly like another's. Correct pressure is one of the biggest contributors to ride quality, tread life, and steering manners on a bias-ply car.

Before taking a 1936 Hupmobile on a longer drive, inspect each tire for cracks, weathering, cuts, bulges, irregular wear, and proper inflation. Confirm that the spare is serviceable, that valve stems are sound, and that the wheel and lug hardware are in good order. On any prewar car, tires should be checked alongside the broader mechanical essentials such as brakes, steering free play, wheel bearings, and cooling-system condition.

A longer outing puts more heat into the tire and asks more of the whole car, so small issues become more significant than they are on a short local drive. If the car has been sitting, take a short test run first and pay attention to vibration, pull, and how the tires settle after a few miles. That cautious approach is usually the best way to enjoy a 1936 Hupmobile without turning a small preventable issue into a trip-ending one.
