Abstract: A tire is described having a carcass structure anchored in each side of the tire in a bead, a reinforced summit, and two sidewall portions joining the summit, each bead having a base, which is intended to be mounted on the tire's design mounting rim, and being extended radially upward by one of said sidewall portions, each bead further having an anchoring zone for anchoring the carcass in the bead, wherein the carcass structure has at least one circumferential alignment of cords in each bead anchoring zone which progressively divides in the respective sidewall portion in at least two circumferential alignments of cords, and wherein a runflat reinforcing member is disposed between the two carcass cord alignments and wherein the runflat reinforcing member is in direct contact with the cords of the two circumferential alignments.
