PNEUMATIC RADIAL TIRE FOR AIRCRAFT

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic radial tire for an aircraft capable of improving durability of a belt part by effectively restraining the propagation of a standing wave phenomenon to a shoulder part. SOLUTION: Strip materials S are constituted so as to be folded back while drawing a circular arc of the radius of a curvature R by both side belt ends x, x, the strip materials S are made to be accumulated in three to seven layers on both end parts of a belt body by setting the ratio R/BW of the radius of the curvature R and the width BW of the belt body as 2.0 to 3.0, and the relation of a distance SA of the end part of a belt layer 6 and the end part of a belt layer 7 and a strip material width SW 0<SA/SW<1.0 on the pneumatic radial tire for the aircraft constituted of the belt layer 6 made of two layers of strip material layers wound around the outside of a carcass layer by folding back the strip materials S at the both side belt ends x, x while inclining them relative to the tire peripheral direction T and the belt layer 7 formed by winding the strip material S in the tire peripheral direction so as to cover the belt layer 6.
