PCT No. PCT/FR91/01081 Sec. 371 Date Jun. 24, 1993 Sec. 102(e) Date Jun. 24, 1993 PCT Filed Dec. 30, 1991 PCT Pub. No. WO92/12020 PCT Pub. Date Jul. 23, 1992.The present invention relates to a tire (P) intended to bear heavy loads and inflated to high pressure, particularly suited for use as an airplane tire. In order to improve the fatigue strength of the beads (4), the axially outer plies (3E, 3F) of the carcass reinforcement (3) in the region of the beads (4) have their edges (30E, 30F) disposed between the upturns (30A, 30B, 30C, 30D) of the axially inner plies (3A, 3B, 3C, 3D).
