Abstract

An aircraft tire, the inflation pressure of which is greater than 12 bar, comprises a crown, two sidewalls and two beads, a carcass reinforcement anchored in the two beads and a crown reinforcement. The carcass reinforcement comprises at least two circumferential alignments of first reinforcing threads of high elasticity modulus. The means for anchoring the first reinforcing threads within each bead comprises second reinforcing threads oriented circumferentially and axially bordering the circumferential alignments of the first reinforcing threads, the first reinforcing threads and second reinforcing threads being separated by a layer of mix of very high elasticity modulus.
