The first groove wall has the lower groove wall-top edge extending in a wavy line along the tire circumferential direction in order that a minimum groove wall angle portion and a maximum groove wall angle portion appear alternately. In the first groove wall , the minimum groove wall angle portion and a wide groove section, and the maximum groove wall angle portion and a narrow groove section, respectively, are located at the same position in the tire circumferential direction. The upper groove wall-top edge of the first groove wall extends in a straight line, a wavy line or a zigzag line with an amplitude smaller than an amplitude of the lower groove wall-top edge of the first groove wall",
