Patent ID: 7780806

Claim:
A tire for an aircraft comprising a pair of bead cores, a carcass consisting of one or more carcass plies toroidally extending between the bead cores, a main belt disposed on an outer peripheral side of a crown area of the carcass and consisting of one or more main belt layers having a spirally-wound structure of a non-extensible cord, and a sub belt disposed on the outer peripheral side of the main belt and consisting of one or more sub belt layers having an organic fiber cord extending in a circumferential direction of the tire in a zigzag pattern, wherein the sub belt layer is formed in such a manner that the organic fiber cord is bent in a zigzag pattern with no overlap of each organic fiber cord with itself at each bent portion and is wound several times in the circumferential direction of the tire, and that a crossing angle of the organic fiber cord with respect to an equatorial plane of the tire is within a range between 45 degrees and 90 degrees, and a width of the main belt is within a range between 100% and 110% of a tread contact width, a width of the sub belt is within a range between 80 and 100% of the tread contact width and less than 90% of the width of the main belt, and wherein each sub belt layer is formed by a strip having the organic fiber cord extending in the circumferential direction of the tire in the zigzag pattern, and the strip is formed to extend in the zigzag pattern with a gap having at least the same width as that of the strip between adjacent sections of the strip, and wherein the strip is wound several times in the circumferential direction of the tire so as to fill entirely the gap formed by the zigzag pattern of the strip with a successive winding.
