Abstract: A tire manufacturing method includes providing a green carcass and forming a plurality of green tread segments by a compression molding process. The method further includes assembling the plurality of green tread segments about the green carcass, thereby forming a green carcass and tread assembly, the tread having at least two bars and at least one void. The method also includes introducing the green carcass and tread assembly to a tread negative, aligning the at least two bars with corresponding mold features, and vulcanizing the green carcass and tread assembly.

Abstract: A green tire includes a carcass and a pre-shaped tread. The carcass includes a pair of annular beads and at least one body ply extending between the pair of annular beads. The carcass further includes a circumferential belt. The pre-shaped tread includes a plurality of tread segments, wherein each of the plurality of tread segments includes at least one bar and at least one void.
