ABSTRACT:
A tire tread that is applicable to retread a worn tire carcass. The tire tread includes a cured tread portion having a first shoulder and a second shoulder. A first uncured wing portion extends from the first shoulder and a second uncured wing portion extends from the second shoulder. Further, an end section at each end of the tire tread portion is uncured. When the tire tread is wrapped around the tire carcass to be formed to the tire carcass and form a tire retread, the first and second wing portions extend down the side walls of the tire carcass and the uncured end sections of the tire tread contact each other. The tire carcass is placed within an autoclave, and the autoclave is heated under pressure such that the tire tread is cross-linked to the tire carcass. During the autoclaving step, the uncured wing portions are cured and cross-linked to the side walls of the tire carcass, and the uncured end portions are cured and cross-linked to each other. A mold segment is positioned within the tire tread pattern where the end sections of the tire tread meet in order to prevent the tire tread pattern from being damaged at the uncured end sections during the autoclaving process.
