To provide a motorcycle tire 1 for off-road traveling excellent in grip performance.SOLUTION: A tread part 2 of a tire 1 comprises: a plurality of shoulder blocks 11 forming a tread end Te; and a plurality of middle blocks 12 adjacent to the shoulder blocks 11 at a tire axial direction inner side. A lateral face SU of the shoulder block 11 at the tire axial direction inner side includes: a first lateral face SU1 which extends from an inner edge 11B toward a groove bottom; and a second lateral face SU2 which extends from a bottom side end of the first lateral face SU1 toward the groove bottom. The second lateral face SU2 is a slant face at the tire axial direction inner side relative to the first lateral face SU1. A ratio (Sa/Sb) of a crest part area Sa where a bottom side end SS of the first lateral face SU1 is an apex to a body area Sb including an inner edge 11B is 5% or more.SELECTED DRAWING: Figure 3

    【課題】 優れたグリップ性能を発揮し得る不整地走行用の自動二輪車用タイヤ1を提供する。【解決手段】 タイヤ1のトレッド部2は、トレッド端Teを形成する複数のショルダーブロック11と、ショルダーブロック11のタイヤ軸方向内側に隣接した複数のミドルブロック12とを含む。ショルダーブロック11のタイヤ軸方向の内側の側面SUは、内側エッジ11Bから溝底に向ってのびる第1側面SU1と、第1側面SU1の底側端から溝底に向かってのびる第2側面SU2とを含み、第2側面SU2は、第1側面SU1に対してタイヤ軸方向の内側に傾斜した面である。第1側面SU1の底側端SSを頂点とする山部面積Saの、内側エッジ11Bを含む本体面積Sbに対する比率(Sa/Sb)は5%以上である。【選択図】 図3
