A pneumatic tire (1) comprising a tread portion (2) provided with a pair of shoulder circumferential main grooves (3) disposed one on each side of the tire equator so that the tread portion is axially divided into a crown land region (4C) between the shoulder circumferential main grooves (3), and a pair of shoulder land regions (4E) between the shoulder circumferential main grooves and the tread edges; each shoulder land region (4E) is provided with a circumferential narrow groove (20) and axially inner and outer shoulder oblique grooves (22) and (21) extending therefrom; the axially outer shoulder oblique grooves (21) are inclined with respect to the tire axial direction to one direction; the axially inner shoulder oblique grooves (22) are inclined with respect to the tire axial direction to one direction opposite to that of the axially outer shoulder oblique grooves (21); crown oblique grooves (8) are inclined with respect to the tire axial direction to one direction same as that of the axially outer shoulder oblique grooves (21); imaginary extensions (21K) of the axially outer shoulder oblique grooves (21) are not overlapped with openings (Q1) of the axially inner shoulder oblique grooves (22) at the circumferential narrow groove (20); imaginary extensions (22K) of the axially inner shoulder oblique grooves (22) are not overlapped with openings (Q2) of the crown oblique grooves (8) at the shoulder circumferential main groove (3E), and are not overlapped with openings (Q3) of the axially outer shoulder oblique grooves (21) at the circumferential narrow groove (20); imaginary extensions (8K) of the crown oblique grooves (8) are not overlapped with openings (Q4) of the axially inner shoulder oblique grooves (22) at the shoulder circumferential main groove (3E). |
