Abstract

An advanced tire mold has been developed which offers the advantages of reducing the level of whiskers on the surface of the tire, reduces sticking to the mold, and which facilitates enhanced gas removal. This tire mold includes a mold segment having an inner side for contacting the uncured tire, an outer side opposite to the inner side, and a plurality of vent passages which allow gas to pass from the inner side of the mold segment to the outer side of the mold segment, the vent passages comprising vent slots, wherein each vent slots have an inlet at the inner side of the mold segment, and wherein the vent slots taper from the inlets to the outer side of the mold segment. This tire mold can be comprised of multiple mold segments which can be utilized in a tire curing press.
