Abstract (en)
[origin: WO9852778A1] An improved track belt tire is constructed of a removable tread belt assembly mounted to the outer circumferential surface of a multi-layered tire carcass with an embedded carcass ply having ply turnup ends about the bead wires. The outermost ends of the first and second turnup ends being located radially outward at a distance equal to between about 2 and 3 times the diameters of the bead wires so that the ends of the turnup ends are supported by the flange ends of the tire rim when a tire carcass mounted to the tire rim is deflected. The turnup ends are also supported by first, second, third, and fourth apex elements disposed about each of the bead wires. The ply line of the carcass ply can also follow the natural ply line.
