FIELD: road vehicles. ^ SUBSTANCE: pneumatic tire tread cap has grooves limiting raised repetitive patterns, at least one of which is provided with first cuts and second cuts, each cut being limited by two main side surfaces interconnected by end surface. Bottom surfaces of first cuts and top surfaces of second cuts are functionally intercoupled so that, at any degree of wear of pneumatic tire tread, length of edges on rolling surface is at least 75% of length of said edges in new tire tread cap. ^ EFFECT: improved adhesion of tread and road at any wear, reduced noise in running. ^ 11 cl, 12 dwg, 1 tbl |
