ABSTRACT:
Vehicle tire and a metal sheet mold plate for forming the vehicle tire having at least one axial end section includes a tread that includes sipes running substantially axially in at least one of the axial end sections when viewed from the top (i.e., perpendicular to the tread surface). The sipes are corrugated to form corrugated ridges and valleys that are substantially straight lines diagonally inclined in an oblique plane parallel to the substantially axially running sipes. The substantially axially running sipes may include a first set of sipes and a second set of sipes. The corrugated ridges and valleys of the first set of sipes are oriented, with regard to a radially outward direction, to extend axially inwardly toward (i.e., toward a axial center of the tire). Conversely, the corrugated ridges and valleys of the second set of sipes are oriented, with regard to the radially outward direction, to extend axially outwardly (i.e., away from the axial center of the tire). At least one joint track is also provided that includes the corrugated sipes of the first and second sets of sipes.
