  • Method of retreading a tire with an endless premolded tread
    Patent number: 4088521
    Abstract: The invention is a replacement tread for installation on a tire casing and the method of installing the tread. The replacement tread includes an endless, pre-molded central tread portion having a relaxed diameter less than the inflated diameter of the tire casing. Integral shoulder wings extend downwardly from the central tread portion and define a circular bottom edge. The shoulder wings bias the bottom edges against the tire casing effecting a seal.To install the replacement tread, the tread area of the tire casing is prepared and the tire casing inflated. The replacement tread is expanded and released onto the tire casing. Tension forces hold the replacement tread closely against the tire casing. The tread is stitched under pressure forces to remove entrapped air and to effect a fluid seal between the shoulder wings and the tire casing. Finally, the replacement tread and the tire casing assembly is cured or bonded.
