To provide a pneumatic tire to ensure compatibility between running performance on a paved road surface and running performance on an unpaved road surface.
Since the direction of a blade edge of saw blade-shaped projections T provided on both sides wall surfaces 4 of lug grooves is pointed to a main grooves 1 side in the area from a midpoint A to the main grooves 1 making the midpoint A in the longitudinal direction of the lug groves as a boundary, and pointed to a ground contact end 6 side in the area from the midpoint A to the ground contact end 6, the mud and snow or the like filled in the lug grooves 2 in traveling on the unpaved road surface can be moved to the both directions of the main grooves 2 and the ground contact end 6 respectively and discharged by a flagellar movement of the saw blade-shaped projections T.
