Tread configuration

A vehicle tire having a tread configuration comprising:

• at least two adjacent circumferentially oriented rows of profiled blocks, each of the at least two adjacent rows being separated from one another by a respective circumferential groove, wherein each groove has a base that extends linearly and parallel to a circumferential direction of said tire and has on both sides of said base a respective side wall that extends radially outwardly from said base and forms side walls of said profiled blocks of an adjacent one of said rows of profiled blocks, wherein radially inner end portions of each of said side walls of said circumferential groove form respective linear edges with said base that extend parallel to said circumferential direction, whereas radially outer end portions of each of said side walls of said circumferential groove are essentially oriented in said circumferential direction and form radially outer edges with radially outer surfaces of said profiled blocks, said radially outer edges having a contour formed by circumferentially extending segments that are periodically interrupted by essentially axially extending segments, wherein said radially outer edges of at least one of said two side walls of said circumferential groove are provided with at least one of said axially extending segments in a circumferentially extending portion of each of said profiled blocks of an adjacent one of said rows of profiled blocks to thereby form successive circumferentially extending segments and associated side wall portions in that profiled block, wherein said side wall portions have an alternating greater and then lesser angle relative to a given radial plane, and wherein each side wall portion of a given block, between said radially outer edge thereof and said linear edge at said base, has a non-stepped surface that adjoins said base in a linear edge that is a single straight line for all radially inner end portions of said side wall portions of that block.
