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.
