Abstract:
1. A tire tread comprising circumferentially extending grooves and laterally extending grooves, the circumferentially extending grooves and laterally extending grooves forming at least one circumferentially extending row of blocks wherein each block is defined by two circumferentially extending sides formed by the circumferentially extending grooves, and at least one block is comprised of a multi-planar chamfer extending along at least one circumferentially extending side of the block, the chamfer having an upper surface that, for the circumferential length of the chamfer, splits the side of the block into only two separate portions, the portions being offset by the chamfer upper surface that extends from the tread surface to 100% of the non-skid depth of the tread, creating a biting edge extending along the circumferentially extending side of the block.
