Patent ID: 8584724

Claim:
A pneumatic tire comprising a pair of left and right annular bead portions, a pair of left and right side walls connected to the bead portions, a tread provided between the side walls, a reinforcing carcass layer composed of at least one toroidal carcass ply extending between the bead portions, and a reinforcing belt layer composed of two or more belt plies arranged on the outer periphery of crown of the carcass layer, wherein at least one of the belt plies is a rubber coated fabric obtained by arranging para-aramid cords in parallel so that the para-aramid cords are at an oblique angle with respect to the equator of the tire, the remaining belt ply is a rubber coated fabric obtained by arranging steel cords in parallel so that the steel cords are at an oblique angle with respect to the equator of the tire and that the steel cords cross the para-aramid cords, and the para-aramid cords satisfy the relationship represented by the following formulae (I) to (III): E≦ 32.14× T− 236 (I) E≧ 150 (II) T≦ 19 (III) (where E represents a modulus of elasticity (cN/dtex) at 25° C. under a load of 49 N, and T represents a tensile strength (cN/dtex)).
