Abstract
A vented tire mold is provided that includes a segment member that has a surface that forms the tread surface of a tire and has integrally formed thereon projecting ribs. These ribs have side surfaces that extend perpendicular or at an angle to the surface of the segment member and serve to form a corresponding profiling in the tread surface of the tire. At least one venting gap having specific dimensions is formed in the segment member and extends along a line of intersection between the surface of the segment member and the side surface of the rib.
