A pneumatic tire comprising: a tread portion provided with a pair of shoulder main grooves each being a circumferentially and continuously extending zigzag shoulder main groove located adjacent to a tread edge (Te), a shoulder lateral groove extending axially outwardly from the shoulder main groove and a plurality of central lateral grooves extending axially inwardly from the shoulder main grooves; each shoulder main groove comprising an inner corner portion protruding axially inwardly; each central lateral groove comprising a first groove portion, a second groove portion and a confluence portion at which the first groove portion and the second groove portion meet, each second groove portion including a first element and a second element which are connected so as to form an angle protruding axially inwardly; the confluence portion of the central lateral groove being communicated with the inner corner portion of the shoulder main groove; and the shoulder lateral groove (7) being located so that an extended portion in which the shoulder lateral groove (7) is extended axially inwardly along the extending direction of the shoulder lateral groove (7) overlaps with the confluence portion at least partially, the tread portion further includes a central portion defined between the pair of shoulder main grooves, and the central portion is separated into a plurality of central blocks including a first central block, a second central block and a third central block, characterized in that the first central block is arranged on the tire equator separated by the first groove portions and the first element and the second element of the second groove portions between circumferentially adjacent central lateral grooves. a tread portion provided with a pair of shoulder main grooves each being a circumferentially and continuously extending zigzag shoulder main groove located adjacent to a tread edge (Te), a shoulder lateral groove extending axially outwardly from the shoulder main groove and a plurality of central lateral grooves extending axially inwardly from the shoulder main grooves; each shoulder main groove comprising an inner corner portion protruding axially inwardly; each central lateral groove comprising a first groove portion, a second groove portion and a confluence portion at which the first groove portion and the second groove portion meet, each second groove portion including a first element and a second element which are connected so as to form an angle protruding axially inwardly; the confluence portion of the central lateral groove being communicated with the inner corner portion of the shoulder main groove; and the shoulder lateral groove (7) being located so that an extended portion in which the shoulder lateral groove (7) is extended axially inwardly along the extending direction of the shoulder lateral groove (7) overlaps with the confluence portion at least partially, the tread portion further includes a central portion defined between the pair of shoulder main grooves, and the central portion is separated into a plurality of central blocks including a first central block, a second central block and a third central block, characterized in that the first central block is arranged on the tire equator separated by the first groove portions and the first element and the second element of the second groove portions between circumferentially adjacent central lateral grooves.
