PROBLEM TO BE SOLVED: To provide a pneumatic tire for a motor cycle which can early exert performance thereof when the tire is brand new and allows abrasion of the tire to be visually checked before the brand-new tire sufficiently exerts performance.SOLUTION: The pneumatic tire for a motor cycle comprises an annularly formed tread part, where in the tread part 1 are provided shallow grooves 2 whose width is between 0.1 and 2.0 mm and whose depth is between 0.1 and 2.0 mm. When shallow grooves extending in a tire circumference direction of the shallow grooves 2 are set as circumferential shallow grooves 2a, shallow grooves extending in a tire width direction are set as width-directional shallow grooves 2b, a grounding region during straight travelling of the tread part 1 is set as a center region Tc, and both outsides in the tire width direction of the center region Tc are set as shoulder regions Ts, one of the total of lengths of outlines of the circumferential shallow grooves 2a and the total of lengths of outlines of the width-directional shallow grooves 2b is longer than the other in one of the center region Tc and the shoulder regions Ts.SELECTED DRAWING: Figure 1

    【課題】新品タイヤの性能を早期に発揮させることができ、かつ、新品タイヤが十分に性能を発揮できるまで摩耗したことを目視により確認することができる自動二輪車用空気入りタイヤを提供する。【解決手段】環状に形成されたトレッド部を備えた自動二輪車用空気入りタイヤであり、トレッド部1に、幅0.1〜2.0mm、深さ0.1〜2.0mmである浅溝2が設けられており、浅溝2のうちタイヤ周方向に延在する浅溝を周方向浅溝2a、タイヤ幅方向に延在する浅溝を幅方向浅溝2b、トレッド部1の直進時接地領域をセンター領域Tc、センター領域Tcのタイヤ幅方向両外側をショルダー領域Tsとしたとき、センター領域Tcおよびショルダー領域Tsのいずれか一方において、周方向浅溝2aの輪郭線の長さの合計、および幅方向浅溝2bの輪郭線の長さの合計のいずれか一方が他方よりも長い。【選択図】図1
