To provide a pneumatic tire for a two-wheel vehicle that can improve abrasion resistance without impairing wet performance.SOLUTION: When a region between a center position CL and a shoulder edge of a tread part 1 is divided along a tread surface into quarters in a tire width direction, and when four regions a, b, c and d are defined in order from a center side of the tread part 1, a groove area ratio Xa of the region a is 8%-14%, a groove area ratio Xb of the region b is 26-32%, a groove area ratio Xc of the region c is 27%-33%, and a groove area ratio Xd of the region d is 5%-16%, and a relation of Xc>Xb>Xa is satisfied, where a groove depth in the tread part 1 is relatively shallower on a shoulder side than on the center side of the tread part 1.SELECTED DRAWING: Figure 2

    【課題】ウエット性能を損なうことなく耐摩耗性を改善することを可能にした二輪自動車用空気入りタイヤを提供する。【解決手段】トレッド部1のセンター位置CLからショルダーエッジまでの領域を踏面に沿ってタイヤ幅方向に4等分し、トレッド部1のセンター側から順に4つの領域a,b,c,dを規定したとき、領域aの溝面積比率Xaが8%〜14%であり、領域bの溝面積比率Xbが26%〜32%であり、領域cの溝面積比率Xcが27%〜33%であり、領域dの溝面積比率Xdが5%〜16%であり、かつXc>Xb>Xaの関係を満足すると共に、トレッド部1における溝深さがトレッド部1のセンター側よりもショルダー側で相対的に浅くなっている。【選択図】図2
