PROBLEM TO BE SOLVED: To provide a pneumatic tire which can improve wondering performance without worsening control stability performance. SOLUTION: A plurality of longitudinal grooves extended in the tire peripheral direction and lateral grooves 10 extended in the direction crossing the longitudinal groove from a tread edge are arranged in a tread surface, so as to provide a pneumatic tire formed with a shoulder block 11 arranged in the peripheral direction between the tread edge and the longitudinal groove. In a peripheral directional section of the shoulder block 11, parallel to a tire equator surface, a first arrival wall surface 12 positioned in a block first arrival side A which is the first grounding side of this shoulder block 11 and faced to the lateral groove 10 is made to have a crossing angle a of 5 deg. to 20 deg. relative to a tire normal N and tilted toward the block first arrival side A as the surface 12 directs the outside in the tire radial direction. Furthermore, in a first arrival region of the block first arrival side A apart from the center of peripheral direction length of this shoulder block, one or two sipings 13 extended in the nearly tire axial direction are provided. |
