Tire

Abstract

Provided is a tire in which low rolling resistance is improved by using reinforcing cords containing polyamide multifilaments as reinforcing cords of a reinforcing member of the tire. In a tire (10) that includes at least one belt reinforcing layer (3) covering the full width of a belt (2), the belt reinforcing layer (3) includes, as a constituent, a rubber-cord composite that is formed of a rubber and reinforcing cords containing multifilaments of a semi-aromatic polyamide composed of a polycondensate of an aromatic dicarboxylic acid-containing dicarboxylic acid and a non-aromatic diamine, or a polycondensate of a non-aromatic dicarboxylic acid and an aromatic diamine-containing diamine acid; and, when the width of a maximum-width belt layer constituting the belt (2) is defined as W, a region of at least more than 0.35 W from a tire equatorial plane is a sparse region in terms of the end count of the reinforcing cords in the belt reinforcing layer (3), while regions on the tire width-direction outer side of the sparse region are dense regions.
