A tire tread has two circumferential grooves and a circumferentially extending column of tetragon shaped blocks located between the two circumferential grooves. In the circumferential extending column of blocks, each block is separated from an adjacent block by an inclined lateral groove, the inclined lateral groove forming an angle between 10° to 25° with one of the circumferential grooves. Each block in the column has a circumferential length L greater than the normal pressure footprint length F<SUB>L </SUB>of the tire. The length of the blocks permits the column of adjacent blocks to act as a rib while maintaining desired block characteristics.
