ABSTRACT:
A tread for pneumatic vehicle tires comprising a central row of tread blocks extending in the circumferential direction of the tire and rows of tread blocks arranged in the shoulder regions of the tire is described. The rows of blocks arranged in the shoulder regions of the tire are separated from the central row of tread blocks by circumferential grooves. The edges of the tread blocks which laterally border the circumferential grooves extend inclined relative to the central circumferential plane of the tire. Wave-shaped sipes or knife-cuts are provided in the tread blocks with the tread blocks of the rows of blocks arranged in the shoulder regions of the tire being more pronouncedly divided or split by sipes than the tread blocks of the central row blocks.
