Abstract
A tire for motor cycles has a belt layer containing aromatic polyamide fiber cords spirally wound around a carcass substantially parallel to the equator of a tire, wherein the belt layer is imaginarily divided into a central region (M) and shoulder regions (S and S) at the border points (P and P) spaced apart in the axial direction by a distance of 0.25 times to 0.35 times the tread width (TW) from the equator of a tire and the initial modulus of elasticity of the belt cords in the central region (M) is set to be larger than that of the cords in the shoulder regions (S and S).
