Abstract: A tire having a circumferential tread (300) with segmented sipes (305) is provided. In one embodiment, the tire has tread blocks with sipes having at least three-segments. The sipe may include a first major segment (320,325), a second major segment (330,335), and a minor segment (350,355) connected to both the first major segment and the second major segment. In alternative embodiments, the sipe may include three or more major segments, connected by a plurality of minor segments.

Abstract: A tire mold (200) having a substantially elliptical base surface (210) and a method for making a tire mold are provided. In one embodiment, a user selects a major axis length (M) for the tire mold, then selects a ratio (R) of the major axis length (M) to a minor axis length (M). The tire mold is then formed with a substantially elliptical base surface defined by the first major axis and the selected ratio.
