Tread patterns of tire of heavily loaded truck/trailer

The invention discloses tread patterns of a tire of a heavily loaded truck/trailer. A plurality of longitudinal trenches are uniformly formed in a tread of a tread top part at intervals; the tread between every two adjacent longitudinal trenches is partitioned into a plurality of pattern blocks by circumferentially uniformly distributed transverse thin slots so as to form longitudinal pattern strips; the longitudinal trenches are 8-12mm deep; the widths of the longitudinal trenches are 1/4-1/3 of the widths of the longitudinal pattern strips; included angles between the walls of the longitudinal trenches and the normal of the tread are 5-15 degrees; the transverse thin slots are tilted by forming an angle of 0-5 degrees with the axial direction; the depths of the transverse thin slots are 1/4-1/3 of the depths of the longitudinal trenches, and the widths of the transverse thin slots are 1/4-1/3 of the widths of the longitudinal trenches. Due to the tread pattern structure of the tire, the tire can well hold t
