The invention discloses a tread structure of an all-weather all-season tire. The tread structure mainly comprises duplicate pitches; each pitch comprises a unit I, a unit II, a unit III, a unit IV and a unit V which are arranged in sequence; each unit adopts a dry-land pattern block and a wet-land pattern block which are alternately distributed in the vertical direction; the dry-land pattern blocks and the wet-land pattern blocks between every two adjacent units are also alternately distributed in the transverse direction, and part of the dry-land pattern blocks and the wet-land pattern blocks are staggered. The tread structure integrates the advantages of a summer tire and a winter tire, and can exert the excellent grip on dry land, wet land and a snowfield; on the dry land, the dry-land pattern blocks play a leading role; on the wet land or the snowfield, the wet-land pattern blocks play a leading role; the dry-land pattern blocks and the wet-land pattern blocks are alternately distributed in both the transverse and vertical directions, and simultaneously exert the grip when the all-weather all-season tire gets in contact with the ground; transverse and vertical grooves in each unit are communicated, and sludge discharge channels are formed among the paths, so as to improve the sludge discharge effect; the all-weather all-season tire has the characteristic of being excellent in grip, traction and sludge discharge performance.
