1934 Oldsmobile Tire Fitment Guide

1934 Oldsmobile vehicles use three sizes across two model groups: 550-17 and 650-16 for the 1934 Oldsmobile 6 Cyl., and 700-16 for the 1934 Oldsmobile 8 Cyl. The 550-17 size mounts on a 17-inch rim, while both 650-16 and 700-16 mount on 16-inch rims. Where rim-width guidance is listed, 650-16 fits 4.50- to 5.00-inch rims and 700-16 fits 4.50- to 5.50-inch rims.

That means a 1934 Oldsmobile owner needs to identify the model first, then confirm the wheel diameter on the car before selecting a tire. A six-cylinder Oldsmobile is the most likely place for confusion because it appears in both a 17-inch and a 16-inch fitment. Once the size is confirmed, the remaining decisions are usually brand, tread character, and whether a blackwall, wide whitewall, or double-whitewall look best suits the car.

On a 1934 Oldsmobile, 550-17 is a numeric bias-ply tire size. The "550" identifies the tire's nominal section-width class in period numeric sizing, and the "17" is the rim diameter in inches. It is not a modern metric size, so it does not read the same way as a P-metric or Euro-metric tire.

That size is used on certain 1934 Oldsmobile 6 Cyl. applications and is chosen mainly by owners aiming for an era-correct prewar appearance. Because 550-17 shares neither the same wheel diameter nor the same size designation as the other Oldsmobile sizes used that year, it should not be treated as interchangeable with 650-16 or 700-16. Confirm the wheel itself before moving ahead.

No. The 1934 Oldsmobile lineup does not share one universal tire size across all models. The six-cylinder cars use either 550-17 or 650-16, while the eight-cylinder cars use 700-16. That split reflects real differences in application across the model range, not just cosmetic variation.

For a buyer, that makes model identification especially important on a 1934 Oldsmobile. If you already know you have an 8 Cyl. car, the path is straightforward because 700-16 is the relevant size. If you have a 6 Cyl. car, check whether it is currently on 16-inch or 17-inch wheels and verify that the wheels are the ones you intend to keep, since the two six-cylinder sizes do not mount to the same rim diameter.

1934 Oldsmobile tires are available in several period-style sidewall treatments. The 550-17 size appears in blackwall, wide whitewall, and double-whitewall form. The 650-16 and 700-16 sizes are offered in blackwall and wide whitewall styles. All of the available tires for these Oldsmobile fitments are bias-ply designs, which is in keeping with the era.

Sidewall choice affects the visual character of a 1934 Oldsmobile as much as the tire size itself. Blackwalls generally suit a more understated or utilitarian presentation, while wide whitewalls deliver the fuller prewar luxury look many restorers want. Double whitewalls on 550-17 create an even more stylized period effect, so owners focused on authenticity should compare their car to period photos, club guidance, and the market presentation they are trying to reproduce.

Several brands cover 1934 Oldsmobile fitments. The 550-17 size is available from BFGoodrich. The 650-16 size is offered by BFGoodrich, Coker Classic, Firestone, and Garfield. The 700-16 size includes Lester, Avon, BFGoodrich, and Firestone. All of these offerings are bias-ply tires sized for prewar Oldsmobile applications.

Brand choice on a 1934 Oldsmobile often comes down to the look you want and the exact size your car uses. Some owners prioritize a familiar period brand name, while others are guided more by sidewall style or load information in a particular size. Once the model and wheel diameter are confirmed, compare the available brands within that size rather than assuming the same lineup exists across every 1934 Oldsmobile fitment.

For the 1934 Oldsmobile in 650-16, BFGoodrich and Firestone both offer bias-ply tires sized for 16-inch rims with listed rim-width guidance of 4.50 to 5.00 inches. Each also carries a listed maximum load capacity of 1580 pounds at 32 psi in the examples shown here. The visual difference is that BFGoodrich appears in a 3.75-inch whitewall version, while Firestone appears in blackwall form in this size.

That makes the practical distinction less about basic fitment and more about appearance and brand preference. A restorer chasing a whitewall presentation may naturally focus on the BFGoodrich option, while an owner seeking a blackwall look may lean toward Firestone. Since both share the same listed load-and-pressure figure and the same rim-width range, the deciding factor is usually the style that best matches the car's intended finish.

Rim-width guidance is listed for two of the three 1934 Oldsmobile sizes. The 650-16 size is matched to 4.50- to 5.00-inch rims, and the 700-16 size is matched to 4.50- to 5.50-inch rims. The 550-17 products shown here do not carry a rim-width figure, but they are built for 17-inch wheels rather than the 16-inch rims used by the other two sizes.

Rim width matters because it affects how a bias-ply tire seats and presents on the wheel, especially on a prewar car where stance and sidewall shape are part of the look. If your 1934 Oldsmobile still has its original-style wheels, compare the wheel size and width to the tire's published range before fitting. That is especially helpful when a car has changed hands or been restored over many decades.

Original 1934 Oldsmobile wheels cannot be assumed to work with all three sizes, because the lineup spans both 17-inch and 16-inch fitments. The 550-17 size requires a 17-inch rim, while 650-16 and 700-16 require 16-inch rims. Even among the two 16-inch sizes, the published rim-width ranges are not identical, with 650-16 listed for 4.50 to 5.00 inches and 700-16 for 4.50 to 5.50 inches.

That means wheel compatibility starts with the actual rim diameter and then moves to width. A 1934 Oldsmobile 6 Cyl. car wearing 17-inch wheels is in a different fitment situation than a six-cylinder car on 16s, and an 8 Cyl. car belongs in the 700-16 range. Before changing sizes, inspect the wheels on the car rather than relying on year and make alone.

A stored 1934 Oldsmobile should be kept out of direct sunlight, away from electric motors and other ozone sources, and in a dry, temperature-stable space. Bias-ply tires like the 550-17, 650-16, and 700-16 sizes used on 1934 Oldsmobile cars are more prone to flat-spotting during long static periods than later radial designs, so they benefit from periodic movement or properly placed stands when the car is laid up for a season.

Good storage habits preserve both the rubber and the way the car drives when it comes back out. Keep the tires inflated, avoid resting the car on damp ground, and roll it occasionally if practical. Owners who value sidewall appearance should also clean the tires gently and avoid dressings that can leave residue or accelerate aging, especially on wide whitewalls.

Tires on a 1934 Oldsmobile are usually judged more by age and condition than by mileage, since collector cars often see light annual use. A sensible rule is to begin evaluating them closely once they are five to seven years old and to treat around ten years as the point where replacement deserves serious consideration, even if tread depth still looks healthy. The DOT date code on the tire helps establish age.

That approach is especially important on a prewar Oldsmobile because long periods of storage can age the casing before the tread wears out. Cracking, hardening, repeated pressure loss, or visible distortion matter more than odometer miles on a collector car. If the car is newly acquired, verifying the age of the tires is one of the first maintenance checks worth making.

Tires on a 1934 Oldsmobile should be inspected before every drive and again before any extended outing. Check for sidewall cracking, tread separation, punctures, irregular wear, and pressure loss, and give special attention to the spare if you plan to rely on it. On a bias-ply prewar tire, changes in shape or sidewall condition deserve prompt attention.

Frequent inspection matters because collector cars can spend long intervals parked and then be expected to run at road speeds without much warning if a tire has aged poorly. A quick walkaround before departure is often enough to catch a problem early. If the car has been sitting for months, inspect the valve stems and look closely for flat-spotting or weather checking before returning it to service.

A 1934 Oldsmobile 6 Cyl. would have originally used bias-ply tires, because bias construction was standard across the American passenger-car market in that period. The size used on the car could be 550-17 or 650-16 depending on the specific six-cylinder application and wheel setup. Original-equipment branding could vary by market and delivery history, so the most reliable baseline is the correct size, construction type, and period-appropriate sidewall treatment.

For restoration work, that means starting with the car's actual wheel diameter and then choosing a bias-ply tire that matches the visual character you want to present. Whitewall width and blackwall versus whitewall appearance can influence how authentic the finished car looks. If you are preparing a judged 1934 Oldsmobile, compare the tire choice against factory literature, surviving photographs, and marque-club guidance for your specific body style and market.

Correct tire fitment matters a great deal when showing a 1934 Oldsmobile. Judges and knowledgeable enthusiasts will notice whether the tire size matches the model, whether the construction reflects the period, and whether the sidewall style looks right for a mid-1930s American car. On a prewar Oldsmobile, the wrong wheel diameter or an obviously mismatched sidewall treatment can stand out immediately.

A well-restored car can lose visual credibility quickly if the tires look too modern or too large for the body and chassis. Owners entering formal events should confirm the correct size for the specific model first, then refine the presentation through blackwall, wide whitewall, or double-whitewall choices where appropriate. Event standards vary, so marque specialists and club judging manuals are the best final reference for originality.

For a 1934 Oldsmobile using 700-16, BFGoodrich and Lester offer the same numeric bias-ply size for 16-inch rims, but they differ in presentation and listed specifications. The BFGoodrich example appears as a blackwall Silvertown Classic Bias Ply with a listed maximum load capacity of 1900 pounds at 36 psi and a 4.50- to 5.50-inch rim-width range. The Lester example appears as a wide whitewall bias-ply tire and carries a heavier listed weight than the BFGoodrich example.

That makes the choice especially relevant for a restoration-minded owner. A blackwall BFGoodrich may suit a more restrained period look, while a wide whitewall Lester emphasizes the formal prewar styling many eight-cylinder Oldsmobiles wear well. Since both are in the proper construction family for the era, the decision usually turns on the exact look you want and whether the listed wheel-width guidance matches your wheels.

1934 Oldsmobile tires can be suitable for normal road use when they are the correct size, in sound condition, and operated within their intended limits. All of the available 1934 Oldsmobile fitments here are bias-ply tires. One 700-16 offering, the Avon 700-16C 102/100L, carries an L speed rating, which corresponds to 75 mph. Other examples shown here do not list a speed symbol, so they should be treated conservatively and used in keeping with the character of a prewar car.

In practice, the broader limitation on a 1934 Oldsmobile is often the vehicle itself rather than the tire alone. Braking systems, steering feel, suspension design, and overall chassis age all shape what feels comfortable and responsible on modern roads. Before highway use, make sure the tires are fresh, properly inflated, and matched to the car, then evaluate the entire car as a prewar machine rather than judging the tire in isolation.

Inflation pressure on a 1934 Oldsmobile should follow the correct tire size and the specific tire's published rating rather than borrowing a number from a different size. In the examples here, 650-16 tires are listed at 1580 pounds at 32 psi, while 700-16 examples are listed at 1800 pounds at 36 psi and 1900 pounds at 36 psi, with another 700-16 carrying a 1874-pound load figure. Those are tire ratings, not automatic vehicle settings for every 1934 Oldsmobile.

The practical way to set pressure is to start with the factory recommendation for the car itself, then compare that against the tire maker's published limits for the exact product you are using. Pressure should never be transferred casually from 650-16 to 700-16 or from one Oldsmobile model group to another. Once the car is in service, monitor wear and ride behavior to confirm the pressure remains appropriate.

Before a longer drive in a 1934 Oldsmobile, inspect each tire for cracking, cuts, bulges, embedded debris, and uneven wear, then verify cold inflation pressure and the condition of the spare. Since these are bias-ply fitments, also pay attention to any change in shape after the car has been sitting. A tire that looks visually sound but has lost pressure since the last outing deserves closer inspection before departure.

Tires are only one part of the pre-drive checklist on a car of this age, but they are one of the easiest places to prevent roadside trouble. Pair the tire inspection with a general look at the wheels, brake system, steering response, and fluid condition. On a 1934 Oldsmobile, a careful ten-minute check before a touring event is far better than assuming a collector car is ready simply because it drove well last time.
