The pneumatic tire (1) includes lateral communication grooves (3, 3a, 3b), and circumferential grooves (4). In a tread portion shoulder region, the lateral communication groove (3a) is disposed between a pair of V-shaped crossing grooves (2a, 2b) adjacent in a tire circumferential direction and extends from a tread edge portion toward a tire equatorial plane (CL). In a tread portion center region, the lateral communication groove (3a) communicates with the V-shaped crossing groove (2b) located to a projecting side of the V-shape of the pair of V-shaped crossing grooves (2a, 2b) and does not communicate with the other V-shaped crossing groove (2a) of the pair. The circumferential grooves (4) are disposed in the tread portion shoulder region and extend in the tire circumferential direction, communicating with the V-shaped crossing grooves (2) and the lateral communication grooves (3).
