A die rib for a tire mold defines the inlets to vent passages of the mold through the sides of the die ribs so that the vent passages do not open through the contour surface of the mold. In one exemplary configuration, the invention provides a die rib having a vent inlet disposed along at least one side of the die rib. The vent inlet may be disposed along up to 80 percent of the length of the die rib with at least one foot disposed against the contour surface of the tire mold section.
