A tire mold segment containing a mold surface with a plurality of groove forming and sipe forming protrusions arranged to form tread portions of tires. At the end faces of the tire mold segment, the portion of sipe forming protrusions with an end that terminates at or near the mold segment end face have an increased width to provide a countermeasure against irregular tread wear and tire noise. The sipe forming protrusions having an end that terminates at or near a tire mold segment end face have a width of about 0.7 mm or more. The remaining sipe forming protrusions positioned on the tire mold segment can a reduced thickness to accommodate high sipe density tread designs.
