TIRE

At least one of the one or more main grooves 2 is a meandering main groove 21, the first and second groove walls 2a and 2b of which have an upper and lower groove wall portion, respectively, and the upper groove wall portion is connected to the groove bottom 2c via the lower groove wall portion. The first groove wall 2a has the lower groove wall-top edge 2ale 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 at a predetermined repetition cycle along the tire circumferential direction, and the second groove wall 2b has the lower groove wall-top edge 2ble extending in a wavy line along the tire circumferential direction. In the first groove wall 2a, 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 2aue of the first groove wall 2a 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 2ale of the first groove wall 2a.
