1955 Buick 50 Super Tires

The 1955 Buick 50 Super uses a 760-15 tire size. This is a numeric bias-ply fitment paired with a 15-inch rim, and it is the primary size for the covered 8-cylinder version of the car.

That makes size confirmation fairly simple, but selection still matters. After verifying that the car retains the correct 15-inch wheels, the next step is choosing the right whitewall style, tire series, and construction approach for the way the Buick will be driven and presented.

The 1955 Buick 50 Super uses a 15-inch rim with its primary 760-15 tire size. That rim diameter is central to both staying with a traditional bias-ply tire and evaluating modern radial equivalents tied to the same overall fitment family.

Wheel diameter should be confirmed on the car itself before purchasing tires, especially on an older vehicle that may have seen wheel changes over the years. Rim width also matters, since some tire choices in this size family carry specific wheel-width expectations that can affect fit and appearance.

The 760-15 size uses a vintage numeric bias-ply format. The 760 designates an approximate 7.60-inch nominal section width, while the 15 refers to the wheel diameter in inches.

This older sizing system does not read like a modern metric radial, so it helps to interpret it before comparing alternatives. Once the size is understood, the real decision becomes whether to keep the Buick in a traditional bias-ply layout or compare radial equivalents that preserve the needed 15-inch wheel diameter.

For the 1955 Buick 50 Super, 760-15 is the primary bias-ply tire size. The available products in that original-size format are bias-ply tires, which suit the car’s period-style proportions and traditional sidewall appearance.

That does not prevent a radial conversion, but it does mean the original fitment story starts with bias-ply construction. Owners considering a change should confirm wheel width, tire dimensions, and clearance rather than assuming that any radial with a similar label will behave the same on the car.

Radial equivalents for 760-15 include 215R15, P225/75R15, P235/70R15, and 760R15. Those represent an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial equivalent, respectively.

Each option follows a different sizing convention, so the choice is not just about construction. The equivalent family is associated with a 6- to 8-inch rim-width range, and the car’s actual wheel width, overall tire dimensions, and available clearance should all be checked before making the switch.

A bias-look radial equivalent is available for the 1955 Buick 50 Super in size 760R15. That option is intended for owners who want a radial construction while keeping a more traditional visual presentation than a modern-looking metric radial may provide.

Appearance is only part of the decision, though. A conversion still needs the same basic fitment review as any other radial alternative, including wheel width, overall dimensions, and body or steering clearance, especially if the Buick no longer sits on its original wheel and suspension setup.

Start with the correct 760-15 size and the 15-inch wheel diameter, then narrow the choice by construction, whitewall style, and tire series. For this Buick, the available products are bias-ply tires, so the decision centers on how traditional the car should look and feel in use.

Whitewall presentation has a major effect on the Buick’s visual character, and rim-width compatibility is worth checking on any surviving or replacement wheels. Load capacity can also matter on a full-size 1950s car, so it helps to compare those specifications when choosing among similar-looking options.

The available 760-15 tires for a 1955 Buick 50 Super include both narrow whitewall and wide whitewall styles. Wide whitewall is the more common presentation in this size, with several whitewall widths represented across the available bias-ply offerings.

That choice affects the car’s overall character as much as the tire brand itself. Owners aiming for a more formal mid-1950s look often focus closely on whitewall width, while others simply want a traditional appearance that complements the Buick without chasing an exact restoration-driven presentation.

Tires for the 1955 Buick 50 Super in 760-15 are available from BFGoodrich, Coker Classic, Universal Vintage Tire, and Goodyear. Those offerings span several bias-ply series, including Silvertown Classic Bias Ply, Coker Classic Bias Ply, Universal Classic Bias Ply, and Super Cushion Deluxe.

Brand choice should be weighed alongside sidewall style, tire-series character, and wheel compatibility rather than treated as the only decision. On a collector Buick, appearance goals often narrow the field quickly, especially when comparing narrow whitewall versus wide whitewall treatments in the same basic size.

A 760-15 bias-ply tire is the natural starting point for a period-style 1955 Buick 50 Super. It preserves the original-era sizing format and the tall-sidewall visual balance that suits a full-size Buick from the mid-1950s.

From there, the appearance decision usually comes down to whitewall treatment and the level of restoration authenticity being pursued. Exact originality can vary by vehicle history and trim presentation, so buyers chasing a highly specific result should compare tire appearance against marque references and surviving period documentation.

Tire construction changes more than ride character on a restored 1955 Buick 50 Super. A bias-ply tire keeps the vintage numeric size format and traditional visual profile, while a modern radial equivalent can introduce a different sidewall look even when it remains in the same general fitment range.

That matters on a 1950s Buick because the tire is a visible part of the car’s stance and trim balance. Owners who want radial construction without straying too far from a traditional presentation may prefer to look at the available bias-look radial option before choosing a more modern metric format.

Modifications can absolutely affect tire fitment on a 1955 Buick 50 Super. Wheel diameter, wheel width, suspension height, brake changes, and body or fender work can all alter what fits cleanly, even when the tire size being considered is close to the car’s original 760-15 range.

A collector Buick may have decades of changes behind it, so the safest approach is to inspect the actual setup before choosing tires. Aftermarket wheels and altered ride height are especially important to check when comparing a bias-ply tire with a radial equivalent that may have different section dimensions.

Before driving a 1955 Buick 50 Super on new tires, inspect wheel condition, lug hardware, valve stems, inflation pressure, and basic clearance at the fenders and steering components. It also makes sense to confirm that the suspension and steering are in sound condition on a car of this age.

A fresh set of tires cannot compensate for worn suspension parts or wheel issues. Once the tires are mounted, recheck for rubbing at full steering lock and during suspension movement, then keep an eye on early wear patterns that might point to alignment or chassis problems.

760-15 tires on a collector 1955 Buick 50 Super should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even a car that sees limited mileage can develop age-related tire issues such as cracking, flat spotting, air loss, or sidewall deterioration over time.

Good maintenance includes keeping the Buick away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment during storage. It is also wise to inspect tread, sidewalls, and overall condition before each driving season or any longer trip, especially if the car spends much of the year parked.
