PROBLEM TO BE SOLVED: To provide a weight-reduced pneumatic tire for a motorcycle while preventing deterioration of steering stability.SOLUTION: A carcass ply 26 of a tire 2 is bridged between one bead 8 and the other bead 8 along the insides of a tread 4 and a sidewall 6. A central rubber layer 16 is laminated outside the radial direction of a carcass 10 and extends from one tread end Pe to the other tread end Pe. A pair of side rubber layers 18 are laminated to the axial outsides of the carcass 10 and extend from the tread end Pe to the bead 8. The axial end 16b of the central rubber layer 16 is overlapped with the radial outer end 18c of the side rubber layer 18. Both complex elastic moduli E* of the central rubber layer 16 and the side rubber layer 18 are 30 to 100 MPa.SELECTED DRAWING: Figure 1 |
