Pneumatic radial tire for passenger cars. |
摘要 |
<p>Highly durable, lightweight tires (10) of a pneumatic radial type for passenger cars are constructed with a tread portion (11) having on its outer peripheral surface a plurality of grooves (15) arranged circumferentially of the tire and a belt layer (14) formed from an array of steel cords (14c, 14d) and disposed in the tread. Each of the steel cords results from twisting a selected number of steel filaments each of specified contents of C, Si and Ni and has a specified level of tensile strength. The distance (t) of rubber from a bottom end of each of the grooves to an outer surface of the steel cord array is defined to be of a specified range as determined cross-sectionally of the tire. <IMAGE></p> |
