A cross-section of a tire. Number 12 indicates the radial ply. Numbers 14 and 16 are bias plies. A radial tire (more properly, a radial-ply tire) is a particular design of vehicular tire. In this design, the cord plies are arranged at 90 degrees to the direction of travel, or radially (from the center of the tire).
In this system a tire had a letter, optionally followed by "R" for radial tires, followed by the aspect ratio, a dash and the diameter – C78-15 or CR78-15 for bias and radial, respectively. Each diameter of rim had a separate sequence of load ratings; thus, a C78-14 and a C78-15 are not the same width.
Increased fuel efficiency and tire mileage overcame the higher price of radial construction. According to a 1976 study, more police departments used steel or fabric radial-ply tires than belted bias-ply and bias or cross-ply tires for their pursuit cars. [15] Goodyear Polyglas tires are now manufactured for owners of period cars. [16]
Tire forces are divided into three axes: radial, lateral, and tangential (or fore-aft). The radial axis runs from the tire center toward the tread, and is the vertical axis running from the roadway through the tire center toward the vehicle. This axis supports the vehicle's weight. The lateral axis runs sideways across the tread.
The word tire is a short form of attire, from the idea that a wheel with a tire is a dressed wheel. [3] [4] Tyre is the oldest spelling, [5] and both tyre and tire were used during the 15th and 16th centuries. During the 17th and 18th centuries, tire became more common in print.
The first radial tire developed and produced by Firestone was the ill-fated Firestone 500 radial. Manufacturing of the new tire was performed on equipment designed to manufacture bias-ply tires. [41] During the 1970s, Firestone experienced major problems with the Firestone 500 radial. The Firestone 500 steel-belted radials began to show signs ...
