Zusammenfassung:	A run-flat tire (10) has a radial carcass reinforcement ply (34) extending through a pair of opposing sidewalls and anchored in opposing bead portions (12, 14). At least one of the bead portions has a bead heel (28) and a bead toe (30) wherein the bead heel is radially outward and axially inward from the bead toe. At least one of the bead portions has a bead composite (38) and a bead apex (42) therein. The bead composite has a maximum axial width (W B ), the axial width being measured perpendicular to the tire equatorial plane. The maximum axial width (W B ) is greater than 50% of the maximum axial width (W) of the at least one bead portion, as measured from the opposing axial sides of the bead portion.
