A belt for incorporation into a core of plies and beads formed on a tire core build mandrel where the core is for encapsulating in an elastomeric material, preferably a polyurethane, in a tire formation process, and which belt is formed from like belt sections laid over one another where the one belt section is rotated one hundred eighty degrees around its longitudinal axis with respect to the other, and the belt sections are individually fitted around a tire core crown and the pair of belt sections ends are off-set from one another and are fitted together into a continuous belt. The belt is a weave of Rayon warp and cotton fill cords or filaments with the Rayon warp cords or filaments having a crossing angle of forty-eight to fifty-two degrees and the Rayon warp and cotton cords or filaments, respectively, have selected diameters, to provide for a separation of the Rayon cords or filaments respectively, in a stack of belt sections.
A belt for use in a formation of a tire core that also includes plies and beads where the core is for installation in a mold for forming a polyurethane tire comprising, a pair of identical belt sections for positioning over one another after one belt section has been turned one hundred eighty degrees about a longitudinal axis with respect to the other, and each said belt section is a weave of Rayon warp cords or filaments and cotton fill cords or filaments, where said Rayon warp cords or filaments are essentially parallel and form an angle of from twenty-four to twenty-six degrees to parallel sides of said belt section, and which said belt section has a width to extend across a top or crown surface of a tire core build mandrel, a length to extend around said tire core build mandrel, and with said belt section ends for fitting together.
