A pneumatic tire (1) includes a tread portion (2) provided with a circumferentially extending zigzag shoulder main groove (3) arranged proximate to a tread edge (Te), and a plurality of shoulder lateral grooves (15) each extending axially outwardly from the shoulder main groove. Each of the shoulder lateral grooves includes a first portion (17) and second portion (18). The first portion includes a first groove wall (24) and an axially inner end (17i) connected to the shoulder main groove. The second portion (18) is arranged axially outward of the first portion and includes a second groove wall (26). The second portion has a groove width (W3) and a groove depth greater than those of the first portion. The first groove wall of the first portion and the second groove wall of the second portion are smoothly continued. |
