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).
Savage formed the Savage Tire company, a $5 million corporation formed to make tires and inner tubes. He later moved to San Diego, where he invented radial tires [1] as well as new production methods. [2] [9] Savage formed another gun company with his son, Arthur John, in 1917, but this also failed. Savage later sold Savage Tire in 1919.
Radial tires were introduced to the U.S. market by rivals B.F. Goodrich and Michelin in the late 1960s, and Firestone lacked their own radial tire. 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]
Following the 1968 Consumer Reports announcement of the superiority of the radial design, radial tires began an inexorable climb in market share, reaching 100% of the North American market in the 1980s. [20] Radial tire technology is now the standard design for essentially all automotive tires, but other methods have been used. [26]
The tubeless tire eliminate the need for an inner tube, which improves performance and safety, as well as enhanced comfort for the car's occupants. [5] BFGoodrich produced the first radial tires in the United States in 1965. This innovation made tires even safer as radial tires have longer tread life and permit better absorption of road bumps.

In 1974, Pirelli invented the "wide radial tyre", upon a request from the Lancia rally racing team for a tyre strong enough to withstand the power of the new Lancia Stratos. At that time, racing tyres were either slick tyres made with the cross ply technique (very wide tyres with a reduced sidewall height), or radial tyres , which were too ...
A tubeless tire (also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube.. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim.
The Pirelli Cinturato is a Pirelli-developed car tyre that was the first example of a wrap-around radial tyre structure. It was used to good effect in motorsport, and most modern tyres are based upon the design.
