ABSTRACT:
An aircraft tire has an inflation pressure greater than 9 bar and a deflection greater than 30%. The tire includes a crown, two sidewalls and two beads, a carcass reinforcement anchored in the two beads and a crown reinforcement. The carcass reinforcement includes at least one circumferential alignment of reinforcement elements and the mechanism for anchoring the reinforcement elements within each bead includes circumferentially oriented reinforcement elements axially bordering the circumferential alignments of said reinforcement elements of the carcass reinforcement. The reinforcement elements of the carcass reinforcement and the circumferentially oriented reinforcement elements are separated from each other by a bonding rubber mix of very high elasticity modulus. The circumferentially oriented reinforcement elements are in the form of cables having a penetrability of between 80 and 100%, the breaking load of the cables being greater than 150 daN, and the cables having an elongation at break greater than 4%.
