Abstract
In a tire, a main groove has a bend where the groove wall angle relative to the tread surface normal line changes in a meridian cross-section. In first and second blocks adjacent in a width direction with the main groove therebetween, an angle between a line extended from a ridge line formed by a bend of a first block side groove wall and a line extended from a lug groove wall defining the first block is larger than an angle between a line extended from the ridge line formed by a bend of the second block side groove wall and a line extended from a lug groove wall defining the second block, and an angle of the first block side groove wall to the tread surface normal line is smaller than an angle of the second block side groove wall to the tread surface normal line.
