PROBLEM TO BE SOLVED: To provide a tire for irregular grounds of a motorcycle capable of improving a performance in a wide range from a hard road to a soft road.;SOLUTION: In this tire for irregular grounds of this motor cycle, a negative ratio of a tread 12 is set to 65-97%. Regarding dimension of each block 14, projection length Ls in a tire peripheral direction is set to 0.3% or more of peripheral length of a tread 12 on a tire equator face CL, and projection length Lw in a tire width direction is set to 3.5% of periphery length Wp of the tread 12. Regarding a block number of the tread 12, when a block number of a shoulder area 12sa block number of an intermediate area 12m≥a block number of a center area 12c is satisfied, traction and sludge spin-off property are secured in the center area 12c, and a grip characteristic in a lateral direction is secured in the shoulder area 12s. In the intermediate area 12m, there is an intermediate characteristic between the center area 2c and the shoulder area 21s, so that a performance can be improved in a wide range from the hard road to the soft road.;COPYRIGHT: (C)2005,JPO&NCIPI
