Abstract

A tread surface profile including a three-part configuration. A circumferentially extending, centrally disposed, linear or zigzagged rib has connected on both sides thereof a plurality of central blocks that are separated from the rib by shallow and narrow venting grooves. On both sides of the rib, pluralities of profiled blocks that extend from a tire shoulder toward the rib, with the profiled blocks being separated from the central blocks of the latter by longitudinal, circumferentially extending channels, and being separated from one another by lateral channels. The profiled blocks and the central blocks are arranged in S-shaped configurations that extend over the width of the tread surface in a diagonal fashion. The shoulder end of each profiled block is oriented axially at an angle of from 90.degree. to 80.degree. relative to the central tire plane, and each rib end of the central blocks is oriented circumferentially at an angle of from 35.degree. to 55.degree. relative to the central tire plane. The lateral channels are connected to one of the longitudinal channels, with at least a portion of the latter being circumferentially oriented at an angle of from 0.degree. to 65.degr…
