To provide a pneumatic tire for a two-wheel vehicle that can improve abrasion resistance without impairing wet performance.SOLUTION: A tread part 1, four or more circumferential grooves 10 forming a zigzag shape are formed and having groove width becoming relatively narrower at a center side, a plurality of lateral grooves 20 which extend from a circumferential groove 12 positioned closest to a shoulder side of the tread part toward the center side are formed. The lateral grooves include first lateral grooves 21 whose level is raised and second lateral grooves 22 whose level is not raised. The first lateral grooves and the second lateral grooves are arranged alternately along a tire circumferential direction, groove depths of the circumferential grooves and the lateral grooves become relatively shallower at the shoulder side. A pitch A of the circumferential groove 11 positioned closest to the center side of the tread part with respect to an extension width TDW of the tread part satisfies a relation of 0.2≤A/TDW≤0.4. A center land part 31 is sectioned between a pair of circumferential grooves, and a minimum width B of the center land part with respect to the extension width TDW of the tread part satisfies a relation of 0.1≤B/TDW≤0.3.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にジグザグ形状をなす4本以上の周方向溝10が形成され、溝幅がセンター側で相対的に狭くなっており、トレッド部の最もショルダー側に位置する周方向溝12からセンター側に向かって延びる複数本の横溝20が形成され、横溝は底上げされた第1横溝21と底上げされていない第2横溝22を含み、これら第1横溝と第2横溝がタイヤ周方向に沿って交互に配置され、周方向溝及び横溝の溝深さがショルダー側で相対的に浅くなっており、トレッド部の最もセンター側に位置する周方向溝11の周期Aがトレッド部の展開幅TDWに対して0.2≦A/TDW≦0.4の関係を満足し、一対の周方向溝の相互間にセンター陸部31が区画され、センター陸部の最小幅Bがトレッド部の展開幅TDWに対して0.1≦B/TDW≦0.3の関係を満足する。【選択図】図2
