摘要： In a pneumatic tire 10, inclined grooves 120, 170 are formed, the groove 120 with groove depth becoming larger and groove width in circumferential-direction becoming smaller as the groove 120 extends toward the inner side in width—direction, the groove 170 with groove depth becoming larger and groove width in the circumferential-direction becoming smaller as the groove 170 extends toward the outer side in the width-direction.. An outer end portion of the groove 120 in the width—direction is continuous with a land portion 110 and an inner end portion of the groove 120 in the width-direction extends toward circumferential groove 22 along an end portion of a land portion 160 in the circumferential-direction. An inner end portion of the groove 170 in the width-direction is continuous with the land portion 160 and the groove 170 extends along an inner end portion of the land portion 110 in the width-direction.
