PNEUMATIC TIRE HAVING A DISSYMMETRIC SIDE WALL STRUCTURE FOR IMPROVING UNIFORMITY BY MAKING THE WIDTH LENGTH OF A BELT FORMED AT THE SHORT SIDE WALL SHORTER THAN THE WIDTH LENGTH OF THE BELT AT THE LONG SIDE WALL

摘要

PURPOSE: A pneumatic tire having a dissymmetric side wall structure with improved uniformity is provided to induce uniform expansion of the tire in supplying pneumatic pressure by making the width length of a belt formed at the short side wall shorter than the width length of the belt at the long side wall. CONSTITUTION: In a pneumatic tire having a dissymmetric side wall structure about a center line(C-C), a length(b) of the width of a belt formed at the short side wall is shorter than a length(a) of the width of the belt formed at the long side wall. The short width length of the belt is 85¯95% of the long width length of the belt. If the short width length of the belt is smaller than 85% or exceeds 95%, the tire is expanded ununiformly in a width direction.
