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

A radial tire for aircraft use comprising;

• a toroidal carcass layer comprising;
• at least one carcass ply having cords embedded therein intersecting at angles within a range of 70.degree. to 90.degree. with respect to an equatorial plane of the tire, a tread arranged radially outwardly of the carcass layer, and a belt layer arranged between the carcass layer and the tread, said belt layer constructed by laminating at least one circumferential breaker ply and at least three intersecting breaker plies, said circumferential breaker ply having cords embedded therein substantially in parallel with said equatorial plane, said intersecting breaker plies having cords embedded therein intersecting at angles within a range of 10.degree. to 70.degree. with respect to the equatorial plane, wherein all of said circumferential breaker plies are arranged radially inwardly of a breaker ply positioned from the innermost breaker ply corresponding to a ply number which is obtained by multiplying all of the breaker plies at a center portion of the belt by 3/4 and rounding to the nearest positive integer to determine said ply number for positioning said circumferential breaker, both radially outermost and innermost breaker plies of said belt layer are constituted by intersecting breaker plies, and both width edges of said innermost breaker ply are folded radially outwardly and said circumferential breaker ply is arranged radially outwardly of folded width edges of the intersecting breaker ply.
