[0033] The rectangular DEFG surface is provided with rolling texture 8.

[0034] The tread pattern adopts an equal pitch design with a pitch number of 45-50.

[0035] The width of grooves I 6, II 5, and III 7 is 0.5mm-1mm; the depth ratio of grooves I 6, II 5, and III 7 is 2:2:1; the angle between groove II 5 and the horizontal direction of the tire is 20°-25°; grooves I 6 and III 7 are perpendicular to the horizontal direction of the tire; the tread ribs are divided by grooves I, II, and III of varying depths, which improves the overall rigidity of the tread blocks.
