PURPOSE: A relatively light tire of all terrain having a relatively low weight center is provided to prevent a bad affect on the stability of traveling and the abrasion of a tread. CONSTITUTION: A tire(10) of all terrain vehicle is prepared with a specially designed tread(12) for mud traction having long rugs(40,42), two shoulder rows(1,2) and four circumferential directionally repeated rows(1,2,3,4) of two central rows(3,4). Herein, a shoulder block(44) is close to the end (45) on the shaft directional outside of the rug(42) of the central rows(3,4), and the tread has a soil discharging channel(60) extended between the rugs in a shaft direction. In addition, each channel is aligned in one or more than one shaft direction and is opened in two positions to the soil emitting channel, and it is desirable for each position to have 20% of shaft directional arc width of the half of the tread so that the washing force of the tread is improved when a tire rotates since the soil can freely move to a rear channel from a front channel.
