Abstract

PURPOSE: To improve the durability of a belt, of the title tire having multiple belt layers, by forming a 1st belt layer in a split construction at a given cord angle, placing a given inextensible fibre cord on its separated portion, and allowing the cords of a 2nd and a 3rd belt layers to be intersected to each other at a given cord angle.
CONSTITUTION: A 1st layer 4a near the carcass layer 3 of a belt layer 4a is allowed to be separated from each other at a crown center area T so as to be provided at respective shoulder portions S, S' to form a split construction. Also the cord angle of the belt layer 4a is set for 40W75deg. and inextensible cords 5, the sum of tensile elasticity for the total number of the cords being 1.3×103kgf/cm, is placed at the separated portion at an angle less than the min. placement angle excluding 0deg., of a 2nd and a 3rd layers 4b, 4c. Additionally, the cord placement angle for the 2nd and the 3rd layers 4b, 4c are set to be the min. 10deg. and the max. 30deg. and the both layers are placed so as to be intersected to each other. This constitution ensures the improvement of the durability and the dimensional stability on a rough road, of the tire, resulting in the improvement of durability.
