Aircraft tire including reinforcement inserts

Abstract

An aircraft tire 10 has at least two circumferentially extending reinforcement inserts. At least one pair of reinforcement inserts 90 is located on each side of the tire. Each insert 90 preferably has two cord reinforced members 91, 92 having bias angled cords. The cords are equal but opposite in orientation relative to the cords of the adjacent member. The pairs of reinforced members 91, 92 extend from the bead portions 18, 20 and terminate in a radially upper portion of the sidewalls 14A, 16A. In the preferred embodiment, each bead portion 18, 20 includes three substantially inextensible bead cores 50, 52 and 54. Each pair of members 91, 92 is interposed between a pair of carcass plies 36, 37, 38, 39, 40, 41, 42, 43 on the ply side of the tire 10. This structure can increase tire durability while at the same time achieve a significant weight reduction.
