Abstract
To provide a motorcycle tire 1 for traveling on an irregular ground excellent in grip performance.SOLUTION: A tread part 2 of a tire 1 includes: a plurality of shoulder blocks 11 forming tread ends Te; and a plurality of middle blocks 12 which are adjacent to inside of a tire axial direction of the shoulder blocks 11. An inner side edge 11B of a tread of the shoulder block 11 in a tire axial direction protrudes outside in a tire radial direction relative to a virtual profile 18 where a tread profile of the middle block 12 is extended to the shoulder block 11. A lateral face S of the inside of the shoulder block 11 in the tire axial direction includes: a first lateral face S1 extending from the inner side edge 11B to a groove bottom; and at least one of second lateral faces S2 extending from a bottom side edge of the first lateral face S1 to the groove bottom in which the second lateral face S2 is slant toward inside in the tire axial direction relative to the first lateral face S1.SELECTED DRAWING: Figure 3
