The invention relates to a truck tyre structure, in particular to a tread pattern structure of heavy-duty truck tyre tread. The heavy-duty truck tyre tread comprises a central pattern block, a lateral small pattern block and a tyre shoulder pattern block, wherein the central pattern block is of a transverse pattern block, the lateral small pattern block and the tyre shoulder pattern block are regularly arranged at the left side and the right side of the central pattern block from interior to exterior, the central position of the central pattern block, namely, a central line of the tread is provided with a central longitudinal circumferential pattern groove, and the central pattern block is evenly divided into a left part and a right part which are symmetrical by the central longitudinal circumferential pattern groove; the central pattern block and the lateral small pattern block as well as the lateral small pattern block and the tyre shoulder pattern block are separated by a longitudinal circumferential pattern groove; and the two adjacent central blocks, the two adjacent lateral small pattern blocks and the two adjacent tyre shoulder pattern blocks are separated by a transverse pattern groove. The tyre tread adopts mixed patterns and has enough braking force, favorable maneuvering performance as well as attractive and elegant appearance.
