In a motorcycle tire, since a reinforcement cord that constitutes a belt layer (24) is constituted by a cord having a low modulus of elasticity (a tensile force upon 1% elongation is 15 N or less), a shearing force in a circumferential direction of a tread (26) is decreased. As a result, a value of frictional energy is decreased, and abrasion resistance of the tread (26) (a center section (27)) is improved. Moreover, since tan δ of shoulder sections (28) is larger than tan δ of the center section (27), a grip limit in the shoulder sections (28) that are grounded upon turning is increased, and turning performance is improved.
