The pin groups 10 are a linear type, a V-shaped type, an inverted-V-shaped type, an N-shaped type, and an inverted-N-shaped type. In each of the pin groups 10, pin positions 9 are sequentially set from one end 3a to the other end 3b on the tread surface 3, and a stud pin 1 is buried at each of the pin positions 9. The stud pins 1 are arranged substantially irregularly or randomly. |
