Buick 60 Series Tires

Buick 60 Series uses seven listed sizes across 1930 through 1938: 31X7.00 and 700-19 for 1930, 550-19 for 1931, 6.00-18 for 1932, 6.50-17 for 1933, 750-16 for 1934-1935, and 700-15 for 1936-1938. The corresponding rim diameters confirmed in available products are 19 inches for 700-19 and 550-19, 16 inches for 750-16, and 15 inches for 700-15, while the year-based sizes 6.00-18 and 6.50-17 indicate 18-inch and 17-inch rims directly in the size code.

The practical takeaway is that Buick 60 Series fitment follows the model year closely, but 1930 needs extra attention because two sizes are listed. Start by confirming the year, then measure or verify the wheel diameter on the car itself before moving to tread style or sidewall appearance. That step matters more here than jumping straight to the tire name.

On Buick 60 Series, 31X7.00 is an older diameter-by-section size. The 31 refers to the tire’s approximate outside diameter in inches, while 7.00 is the nominal section width. That means the first number is not the wheel diameter, which is the point that often confuses modern buyers working with early 1930s fitment.

The important step is to treat 31X7.00 as a dimensional description rather than a modern wheel-size code. If your Buick 60 Series is a 1930 car, verify the actual wheel fitted to the car and compare it with original service literature, surviving wheel markings, or a Buick specialist. That is the safest way to separate a true 31X7.00 application from the alternate 700-19 listing shown for the same year.

The 1930 Buick 60 Series is the only year in this range with two listed sizes: 31X7.00 and 700-19. That means year alone is not enough to identify the correct tire for every 1930 car. The split should be treated as a configuration difference that needs to be verified on the individual vehicle.

A 1930 Buick 60 Series owner should inspect the wheel and compare the car against original references before selecting a tire. Look for wheel diameter markings, check whether the car remains on its original wheels, and confirm whether an earlier restoration changed anything. That extra verification matters more than assuming every 1930 Buick 60 Series used the same casing.

Buick 60 Series used several rim diameters during 1930-1938. The range begins with 19-inch wheels in 1930 and 1931, shifts to 18-inch in 1932, 17-inch in 1933, 16-inch in 1934 and 1935, and 15-inch in 1936 through 1938. With the older 31X7.00 style, the size itself does not give you the wheel diameter, so the rim must be confirmed separately.

That sequence makes wheel verification a first-step fitment check on Buick 60 Series. A car that has had wheels swapped during restoration can easily send you toward the wrong tire if you rely only on model year memory or registration paperwork. Measure the wheel, inspect stampings where possible, and use the year listing as a guide rather than a substitute for checking the car in front of you.

A 1934 Buick 60 Series uses 750-16 in the listed year range, which places it on a 16-inch rim. That gives you a strong year-specific starting point, but the right confirmation process still includes checking the actual wheel diameter on the car and making sure the car has not been altered with parts from another year in the Buick 60 Series line.

Once the 16-inch wheel is confirmed, the next choice is between a passenger-car bias-ply tire and one of the heavier-duty truck or military-style offerings that also exist in 750-16. A restoration-focused Buick 60 Series usually points toward passenger-car tread and sidewall styling, while a utility or specialty build may steer differently. Size first, wheel second, usage third is the best order.

Buick 60 Series tire offerings include blackwall, wide whitewall, and double-whitewall styles, although the exact choices vary by size. For example, 700-19 includes blackwall, wide whitewall, and double-whitewall options, while 550-19, 750-16, and 700-15 also include blackwall and wide whitewall choices. That gives restorers room to match the visual character of the car while staying within the correct size family.

The right sidewall style depends on how your Buick 60 Series is being finished and what period look you want to preserve. A restrained driver or commercial-looking build often suits blackwalls, while a more formal restoration may call for a wide whitewall. The key is to settle the correct size and wheel diameter first, then choose the sidewall treatment that best fits the car’s presentation.

Buick 60 Series tire options in the listed range come from Firestone, Lester, BFGoodrich, and STA. Brand availability depends on the size: some sizes are concentrated in one or two brands, while 750-16 and 700-15 include a broader spread of offerings. The product range also spans different series, from classic passenger-car bias-ply tires to military and transport-pattern tires.

For a Buick 60 Series owner, brand should usually be chosen after the size, wheel diameter, and intended use are established. A judged restoration may prioritize a certain tread look or sidewall style, while a practical tour car may focus on the overall period-correct category. Comparing the series within the correct size will tell you more than choosing by brand name alone.

Buick 60 Series offerings include Firestone Balloon, Firestone Classic Bias Ply, Lester Classic Bias Ply, Silvertown Classic Bias Ply, Firestone Classic Military, Super Traxion, Super Transport, Transport Highway, and Traxion. Those series break into two broad groups: period passenger-car bias-ply tires for original-style road-car presentation, and heavier-duty truck or military-pattern tires intended for a very different appearance and service character in the same nominal size.

That distinction matters most in 750-16 and 700-15, where the size alone does not tell the whole story. A Buick 60 Series restored as a passenger automobile will usually point toward the classic bias-ply families, while transport, NDCC, NDT, or traction-type patterns create a more utilitarian look. When comparing series, consider not only dimensions but also tread pattern, sidewall treatment, and the car’s final purpose.

A Buick 60 Series should be stored in a cool, dry, dark space away from direct sunlight, ozone sources, and long exposure to heat. Clean floors, proper inflation, and avoiding contact with petroleum products all help protect collector tires. On a prewar car, preserving the casing matters as much as preserving tread depth because these cars often accumulate miles slowly.

If a Buick 60 Series will sit for extended periods, move it occasionally or use methods that reduce flat-spotting and localized stress. Keep the car out of prolonged dampness, and do not let one corner carry load on an underinflated tire. Good storage habits are one of the simplest ways to extend tire life on a low-use collector Buick.

Tires on a Buick 60 Series should be inspected before any meaningful drive and again during routine service intervals, even if the car covers very few miles. Check inflation, cracking, tread separation signs, sidewall damage, valve hardware, and overall casing condition. On a prewar automobile, long parked periods can age tires more noticeably than steady use.

A practical routine is to inspect a Buick 60 Series at the start of each driving season and before tours, shows, or longer outings. If the car still uses tube-type bias-ply tires, pay close attention to how the tire is seated and whether the wheel hardware is sound. Frequent visual checks catch age-related problems before they become roadside failures.

A Buick 60 Series tire should be replaced when age, cracking, hardening, bulges, separation, or other structural deterioration appears, even if the tread still looks usable. Collector tires often time out before they wear out. That is especially true on prewar cars, where modest annual mileage can hide the fact that the casing has become too old for dependable road service.

Replacement decisions on Buick 60 Series should be driven by condition and age rather than tread depth alone. If the car has spent years parked or if a tire’s history is uncertain, have it evaluated before continued road use. A good-looking old tire can still be unfit for service, and a conservative approach is the right one on a car of this era.

Buick 60 Series was fitted across a wide span of early-1930s sizes, moving from 31X7.00 or 700-19 in 1930 to 550-19, 6.00-18, 6.50-17, 750-16, and finally 700-15 by 1936-1938. Available series include passenger-car offerings such as Firestone Balloon, Firestone Classic Bias Ply, Lester Classic Bias Ply, and Silvertown Classic Bias Ply. That range shows that year and wheel diameter are central to identifying an authentic fitment.

For restoration work, the exact original tire for a specific Buick 60 Series should be matched to the car’s year and surviving factory references, not chosen by appearance alone. Sidewall style and tread family can influence judging and authenticity just as much as nominal size. If the car has a long restoration history, verify that the current wheels match the year you are restoring.

Correct tire fitment can absolutely affect how a Buick 60 Series is viewed in restoration circles because wheel diameter, tire profile, tread style, and sidewall treatment all shape the car’s stance and period character. A prewar Buick on the wrong diameter tire can look visibly incorrect even to a casual observer. Judges and experienced marque enthusiasts often notice those details quickly.

For a Buick 60 Series aimed at serious presentation, use the year-specific size first, then choose a sidewall style and series that suit the era of the car. Marque clubs, original literature, and period photographs are useful references when deciding between blackwall and whitewall presentation. Small visual differences in tire choice can make a meaningful difference to authenticity.

Buick 60 Series restoration choices in the available range include blackwall, wide whitewall, and in at least one 700-19 application, double-whitewall. All three are period-appropriate visual directions within the broader prewar context, but they do not suit every restoration equally. The right answer depends on the year of the Buick 60 Series and the character of the finished car.

A more restrained Buick 60 Series restoration often leans toward blackwalls, while a dressier presentation may call for a wide whitewall. Double-whitewall treatment should be used carefully and with an eye toward the exact look you are trying to achieve. Once the correct year-specific size is settled, sidewall style becomes one of the most important authenticity decisions on the page.

A Buick 60 Series can be driven on public roads when it is fitted with the correct size tire, the tires are in sound condition, and the rest of the car is mechanically ready for road use. Most available Buick 60 Series options here are bias-ply tires, which are appropriate to the era but drive differently from modern radials. Safety depends on the full condition of the vehicle, not just the tire size printed on the sidewall.

Before taking a Buick 60 Series into traffic, make sure steering, brakes, wheels, alignment, and inflation are all checked with the same care as the tire selection itself. Keep expectations realistic for a prewar automobile, especially one that sees infrequent use. A properly sorted car on the right tires can be enjoyable, but it should always be driven with period-correct caution.

Before driving a Buick 60 Series, inspect tire inflation, visible casing condition, valve hardware, tread surface, and any signs of cracking or separation. Also confirm that the wheel diameter and tire size match the car’s year and current wheel set. Since Buick 60 Series moved through several wheel diameters from 1930 to 1938, a mismatch can create fitment and handling problems before the car even leaves the garage.

A sensible pre-drive routine for Buick 60 Series also includes checking brake function, wheel security, steering response, and whether the car has been sitting long enough to develop flat spots. On collector cars, problems often come from storage and age rather than fresh wear. A few minutes of inspection is far easier than dealing with a preventable roadside issue.

A Buick 60 Series on original-style bias-ply tires should be driven at conservative, mechanically sympathetic speeds that suit a prewar automobile rather than modern highway expectations. Even with fresh tires in the correct size, the chassis, steering, braking, and tire construction belong to an earlier road era. The car should feel settled and predictable, not hurried.

For real-world use, let the condition of the Buick 60 Series and the type of road determine your pace. Smooth secondary-road touring is usually far more appropriate than sustained fast traffic running, especially if the car is freshly restored or only occasionally exercised. The goal is stable, controlled progress that respects both the tire construction and the age of the machine.
