A pneumatic tire has tread blocks (5) each defined by an equator-side longitudinal groove (3A), a tread-edge-side longitudinal groove (3B), a heel-side transverse groove (4A) and a toe-side transverse groove (4B). The block (5) has an equator-side longitudinal wall surface (8a) having a first radially outer edge (9a) and a first radially inner edge (10a), and a tread-edge-side longitudinal wall surface (8b) having a second radially outer edge (9b) and a second radially inner edge (10b). The angle α1U of the first radially outer edge (9a), the angle α1L of the first radially inner edge (10a), the angle α2U of the second radially outer edge (9b) and the angle α2L of the second radially inner edge (10b), each with respect to the tire circumferential direction, satisfy the following four conditional expressions: (0≰α1L<α1U≰45); (0<α2L<α2U≰45); (α1L<α2L) and (α1U<α2U).
