Pneumatic radial tires for passenger cars |
摘要 |
A high-speed running pneumatic radial tire comprises a cylindrical crown portion, a pair of sidewall portions extending inward therefrom, a radial carcass extending from one of the sidewall portions through the crown portion to the other sidewall portion, and a belt and a tread successively superimposed on the crown portion outward in the radial direction of the tire. The tread has plural rows of blocks defined by plural circumferential grooves and many lateral grooves, and the belt is comprised of at least two main crosscord belt layers and an auxiliary belt layer arranged thereon. The auxiliary belt layer is formed by spirally winding a rubberized ribbon ply of heat-shrinkable cords on the main belt layers, in which an overlapped amount of the ribbon ply is made large in a zone of the tread substantially corresponding to the block row than in a zone of the tread substantially corresponding to the circumferential groove.
