A pneumatic tire includes a pair of circumferential grooves, a plurality of lateral grooves, and longitudinal grooves communicating between the lateral grooves on the outsides, in a tire width direction, of the circumferential grooves. Each lateral groove includes a lateral groove first portion, a lateral groove second portion disposed further outward, in the tire width direction, than the lateral groove first portion, and a lateral groove step portion connecting the lateral groove first portion and lateral groove second portion. The groove width center of the outer end, in the tire width direction, of the lateral groove first portion is disposed closer to one tire circumferential side than the groove width center of the inner end, in the tire width direction, of the lateral groove second portion. The longitudinal grooves are inclined, relative to the tire circumference direction, toward the side opposite the side the lateral groove step portion extends. The end portion on the one tire circumferential side of each longitudinal groove joins an area where the lateral groove second portion and the lateral groove step portion of the lateral groove on the one tire circumferential side join together. The end portion on the other tire circumferential side of each longitudinal groove joins an area where the lateral groove first portion and the lateral groove step portion of the lateral groove on the other tire circumferential side join together. |
