Patent ID: 7905262

Claim:
A tire for a motorcycle comprising a tread, wherein the tread includes a center region, a pair of shoulder regions and a pair of middle regions positioned between the center region and the shoulder regions, the center region, the shoulder regions and the middle regions are formed by crosslinked rubber compositions, and a modulus Mm of the rubber composition in the middle regions is lower than a modulus Mc of the rubber composition in the center region and is higher than a modulus Ms of the rubber composition in the shoulder regions; wherein a difference (Mc−Mm) is equal to or greater than 0.4 MPa and is equal to or smaller than 1.1 MPa, a difference (Mm−Ms) is equal to or greater than 0.4 MPa and is equal to or smaller than 1.1 MPa, wherein the moduli Mc, Ms and Mm imply a tensile stress in an elongation of 300% at 100° C., wherein the modulus Mc is equal to or higher than 3.7 MPa and is equal to or lower than 5.7 MPa, the modulus Ms is equal to or higher than 2.5 MPa and is equal to or lower than 3.5 MPa, and the modulus Mm is equal to or higher than 2.7 MPa and is equal to or lower than 4.7 MPa, and wherein a hardness of the center region is equal to or higher than 35 and is equal to or lower than 45, a hardness of the shoulder region is equal to or higher than 30 and is equal to or lower than 35, and a hardness of the middle region is equal to or higher than 30 and is equal to or lower than 40 when the tread is held in an environment of 100° C.
