PROBLEM TO BE SOLVED: To provide a pneumatic tire for motor cycle in which grip performance and steering performance are made compatible without impairing abrasion resistance of the tire.SOLUTION: A pneumatic tire for a motor cycle has bent main grooves 8 constituted of first grooves 6 and second grooves 7 provided on a step face of a tread. Angles θ1 of the first grooves 6 relative to a circumferential direction are set to 12° or more and 26° or less; inclination angles θ2 of the second grooves 7 relative to a tread circumferential direction are set to 50° or more and 70° or less; and the first grooves 6 arranged at a first region P of one half part of the step face of the tread are extended across a tire equator face to the first region P in the other half part of the step face. The tire further has sub grooves 9 arranged across a second region Q and a third region R and extended obliquely in a specified rotating direction of the tire, from inside in a tread width direction toward outside in the tread width direction.

    【課題】タイヤの耐磨耗性を損なうことなく、グリップ性能と操舵性能とを両立させた自動二輪車用空気入りタイヤを提供する。【解決手段】自動二輪車用タイヤは、トレッド踏面に第1の溝6と第2の溝7とからなる屈曲した主溝8を備え、第1の溝6の周方向に対する角度θ1を12?以上26?以下とし、第2の溝7のトレッド周方向に対する傾斜角度θ2を50?以上70度以下とし、トレッド踏面の一方の半部の第1の領域Pに配置される第1の溝6は、タイヤ赤道面を跨いで他方の半部における第1の領域Pにまで延び、第2の領域Qと前記第3の領域Rとに跨って配置され、トレッド幅方向内側からトレッド幅方向外側に向かって斜めに前記指定タイヤ回転方向に延びる副溝9をさらに有することを特徴とする。【選択図】図2
