ABSTRACT:
A method of making a belted tire by first molding and vulcanizing a tire casing which may include carcass plies, tire beads, sidewall and undertread stock. The cured tire casing is mounted on axially movable rings and inflated. The beads of the tire casing are positioned axially so that the tire casing will have substantially the same diameter at the centerplane as the diameter of the finished tire. A narrow, inextensible restrictor band is wrapped centrally around the outer periphery of the tire and adhered thereto by an adhesive. The band is narrow enough not to radically change the operational characteristics of the belt structure, but wide enough to restrict expansion of the portion of the tire casing at the centerplane beyond a desired diameter for receiving the belt structure and tread. The beads are then positioned axially so that the shoulder diameter of the inflated casing is sufficient to provide a surface with the desired contour for receiving the belt plies and tread. A belt structure composed of a plurality of belt plies, separate from the narrow band, is then wrapped around and stitched to the tire casing after which a tread is wrapped around the belt structure. The assembly of tire casing, restrictor band, belt structure, and tread is then placed in a mold where the unvulcanized components of the belt structure and tread are molded and vulcanized.
