PROBLEM TO BE SOLVED: To achieve a vehicular tire that can easily satisfy both of a drainage performance and a steering stability performance.SOLUTION: In inclined grooves 16 of a vehicular tire 10, in-groove land parts 20 are formed to be stood up from bottom wall parts 16F of the inclined grooves 16, and recess amounts of surface parts 20A from a tread step face part 12C in the in-groove land parts 20 are set to the minimum at an innermost side in a tire width direction when viewed from a cross section in a tire width direction. This allows rigidity of a tread center part 12A to be secured. Further, in-groove inclined grooves 32 are constituted among the in-groove land parts 20, inner side wall parts 16D and outer side wall parts 16E, which allows water entering between a tread 12 and a road surface to be exhausted through the in-groove inclined grooves 32a so as to secure a drainage performance.SELECTED DRAWING: Figure 1

    【課題】排水性と操縦安定性とを容易に両立させることができる車両用タイヤを得る。【解決手段】車両用タイヤ10の傾斜溝16には、溝内陸部20が傾斜溝16の底壁部16Fから立ち上げられて形成されており、タイヤ幅方向断面視で溝内陸部20における表面部20Aのトレッド踏面部12Cからの凹み量がタイヤ幅方向最内側で最も小さく設定されている。このため、トレッドセンター部12Aの剛性が確保される。また、溝内陸部20と内側側壁部16D及び外側側壁部16Eとの間に溝内傾斜溝32が構成されている。このため、溝内傾斜溝32でトレッド12と路面との間に入り込んだ水を排出することによって排水性を確保することができる。【選択図】図1
