A motorcycle tire (1) comprises a tread portion (2), the tread portion including a tread rubber portion (2G), the tread rubber portion including a center portion (CR) disposed in a center region of the tread portion including a tire equator (C), a pair of shoulder portions (SH) disposed each side of the tread edge (2t) and a pair of middle portions (MD) each disposed between the center (CR) and shoulder portions (SH) in each side of the tire equator (C), and the center, middle and shoulder portions satisfy the following relations:
E*1 < E*2 < E*3,
0,9 ‰¤ tan´1/tan´2 ‰¤ 1.1, and
0,9 ‰¤ tan´2/tan´3 ‰¤ 1.1,
wherein E*1, E*2 and E*3 are complex elastic moduli of the center, middle and shoulder portions respectively, and tan´1, tan´2 and tan´3 are loss tangent of the center, middle and shoulder portions respectively. |
