Abstract

PURPOSE:To reduce noise without any failure in durability, driving stability, and anti-slip of a tire by properly determining the meridian sectional figure of a tire and the plane tread pattern from many factors. CONSTITUTION:The relation in size among the maximum meridiam sectional width W of a tire, a crown radium R, a breadth B along the crown way, an index pitch P of each lug 7, a lenth L of each horizontal groove along the meridian of a tire, a width Wg of each horizontal groove 7, and a width Wl or each lug 6 is represented by an expression of 0.9W<=R<=1.3W, 0.635W<=B<=0.715W, 0.37B<= P<=0.46B, 0.36B<=L<=0.41B, Wg:Wl=0.5-0.71:1. Each horizontal groove 7 is arranged to eliminate a grade toward the head of each log 6. Air existing in each groove 7 may be easily released from its opening, with the lug 6 successively worn, which takes longer time to earth. Noise can be reduced without a failure in durability of a tire.
