<p>An improved track belt tire is constructed of a removable tread belt assembly mounted to a tire carcass with an embedded carcass ply having ply turnup ends about the bead wires. First, second, third, and fourth apex elements are disposed about each of the bead wires. The first of the apex elements is located adjacent and radially outward from each of the bead wires. The second of the apex elements is located between the overlying sides of the turnup ply. The third of the apex elements is disposed against the axially inwardly facing sides of the turnup ends of the carcass ply and the fourth of the apex elements is located against outwardly facing sides of the ply turnup ends of the carcass ply to encase the end portions of the ply turnup ends between the second and fourth apex elements.</p> |
