Tread patterns of driving tyre of heavy-duty truck

The utility model discloses tread patterns of a driving tyre of a heavy-duty truck. The tread patterns comprise pattern grooves, wherein the plurality of longitudinal pattern grooves are uniformly formed in treads of a crown and a tyre shoulder part at intervals to form a plurality of pairs of longitudinal pattern strips which are bilaterally symmetrical and are bounded by the center of the crown; the longitudinal pattern strips are divided by transverse pattern grooves which are uniformly distributed at the periphery into a plurality of pattern blocks; an included angle of 0-5 degrees is formed between the transverse pattern grooves and the axial direction; the widths of the longitudinal pattern strips are gradually increased from inside to outside; the transverse pattern grooves in the outermost longitudinal pattern strip extend to the tread of the tyre shoulder part, and the transverse pattern grooves are internally provided with reinforcing ribs connected with the adjacent pattern blocks. The tread patterns of the driving tyre of the heavy-duty truck disclosed by the utility model adopt a block-shaped pattern design to enhance the driving force of the tyre, so that the tyre has good operation performance and road surface adaptability; a deepened pattern design and a reinforcing rib design for the bottoms of the pattern grooves are adopted so that the tyre is wear-resisting and is durable.
