An annular substantially inextensible bead reinforcing member (36) is positioned in each of the bead portions (16, 18). A carcass ply (30) is positioned in each sidewall (12, 14) and the crown (10) and extends from one of the bead portions (16) to the other of the bead portions (18). A first elastomer reinforcing member (50) is positioned in each bead portion (16, 18) and is disposed axially outwardly of the carcass ply (30) and adjacent the bead reinforcing member (36). A second elastomer reinforcing member (60) is positioned in each bead portion (16, 18) with at least a portion of the second member being disposed axially inwardly of the carcass ply (30) and extending radially outwardly from adjacent the bead reinforcing member (36).</p> |
