The advanced tire null which possesses the tread band which possesses the substratum of the anisotropy which is stabilized vis-a-vis temperature fluctuation

摘要

(57) Abstract This invention, the radial carcass (3) on, the belt layer of one or more which is installed in the position where it increases facing toward outside (7) with, the nylon cord/code which around the belt winding makes helical (8) the reinforcement layer which it possesses and, the radial carcass which it possesses regards the advanced tire which possesses the structure which consists of (3). Profitably, the tread band of the tire is formed the lower stratum (11) with, alternately outside distribution facilities is done layer (12) with by, the aforementioned lower stratum, the elasticity substantially it continues to be constant in the 20C - the 110C and/or possesses hardness quality, the tire in the high-speed time when it can cause the big temperature rise of the rubber compound can guarantee the efficiency which is superior with this way.
