A pneumatic tire is equipped with a tread portion provided with a plurality of shoulder lug grooves spaced apart in a circumferential direction, each extending outward in a tire lateral direction, opening to a ground contact end, and including a closed end inward in the tire lateral direction. In a region of each of the shoulder lug grooves from an end of a belt having a greatest width in a belt portion of the pneumatic tire to an inner side in the tire lateral direction, the shoulder lug groove has a groove width that decreases inward in the tire lateral direction, and includes a portion where a groove cross-sectional area is kept constant by a change in at least one of a groove wall angle or a groove depth of the shoulder lug groove, the portion being provided in the tire lateral direction across a length of at least 20% of half a tire development width.
