Radial tire for aircraft including both a circumferential breaker ply and an intersecting breaker ply

摘要

A radial tire for an aircraft includes a toroidal carcass layer consisting of carcass plies having cords embedded therein intersecting at angles of 70°-90° with respect to an equatorial plane of the tire, a tread rubber arranged radially outwardly of the carcass layers, and a belt layer arranged between the carcass layers and the tread rubber and constructed by laminating circumferential breaker plies and intersecting breaker plies. The circumferential breaker plies have cords embedded therein substantially in parallel with the equatorial plane. The intersecting breaker plies have cords embedded therein intersecting at angles of 10°-70° with respect to the equatorial plane. Both radially outermost and innermost breaker plies of the belt layers are constructed by intersecting breaker plies.
