<p>PURPOSE:To suppress separation between plies in a high-speed heavy-load tire for an aircraft or the like by forming a reinforcing layer of a strip sheet of the specified thickness and width so as to cover the broken end of a carcass or the tread reinforcing ply into U-shape, and specifying the distance between cords. CONSTITUTION:Rubber projecting layers 20A, 20B for covering the respective end parts of the outer ply 14a1 and inner ply 14a2 of a rubber reinforcing layer 20 are covered into U-shape with a strip rubber sheet 16 to perform vulcanization molding. This strip rubber sheet 16 is formed into semi-vulcanized or unvulcanized strip shape of 0.2mm or more and 2.0mm or less in thickness and 20mm or more and 30mm or less in width, and attached in the state of covering the broken end (e) of each ply 14a into U-shape. The distance l between the respective cords 27 of the outer ply 14a1 and inner ply 14a2, the distance l2 between the respective cords 27, 26 of the outer ply 14a1 and a belt ply 10a1, and the distance l3 between the respective cords 27, 25 of the inner ply 14a2 and a carcass ply 7b1 are set 1/4 or more and 2.0 or less as long as the diameter of the cord 27.</p> |
