PROBLEM TO BE SOLVED: To provide a motor cycle tire that can exert large grip force from when the cycle is a new product.SOLUTION: In a motor cycle tire 1, a tread outer surface 2S between tread ends 2t and 2t is curved and extended in a circular shape protruding outside in a tire radial direction, a distance in a tire shaft direction between the tread ends 2t and 2t or a tread width TW has the tire maximum width, and further a tire rotation direction R is designated. At shoulder regions Sh on both sides of the tread outer surface 2S are disposed, at intervals in a tire circumferential direction, recessed grooves 12 extending obliquely toward a distal side in the tire rotating direction, toward the tread ends 2t from a tire equator C side, or linear patterns 11 constituted of protrusions 13. In the linear patterns 11, heights H1 or depths D1 in the tire radial direction are 0.2 mm-0.5 mm and widths W1 perpendicular to a longitudinal direction are 1.0 mm-3.0 mm, and further intervals S1 between adjacent liner patterns are 1.0 mm-5.0 mm.
【課題】本発明は、新品時から大きなグリップを発揮しうる。【解決手段】トレッド端2t、2t間のトレッド外面2Sがタイヤ半径方向外側に凸の円弧状で湾曲してのびるとともに、トレッド端2t、2t間のタイヤ軸方向距離であるトレッド幅TWがタイヤ最大幅をなし、しかもタイヤ回転方向Rが指定された自動二輪車用タイヤ1である。トレッド外面2Sは、両側のショルダー領域Shに、タイヤ赤道C側からトレッド端2t側に向かってタイヤ回転方向Rの先着側に傾斜してのびる凹溝12又は凸条13からなる線状模様11がタイヤ周方向に隔設される。線状模様11は、タイヤ半径方向の高さH1又は深さD1が0.2mm〜0.5mm、長手方向と直角な幅W1が1.0mm〜3.0mm、しかも隣り合う他の線状模様との間隔S1が1.0mm〜5.0mmである。【選択図】図2
