Abstract:
1. A radial tire for an airplane, comprising: a carcass layer which is toroidal, and in which are embedded a plurality of cords which intersect a tire equatorial plane; a tread rubber layer disposed at a tire radial direction outer side of the carcass layer; and a belt layer disposed between the carcass layer and the tread rubber layer, wherein the belt layer has a zigzag endless belt which forms a plurality of layers in a tire radial direction and in which cords, which intersect the tire equatorial plane and which extend in a tire circumferential direction, are bent at both ends in a tire widthwise direction and are disposed substantially uniformly over an entire region, and an inner side cord portion, which structures an inner side belt layer within the belt layer, intersects the tire equatorial plane at a first angle, and an outer side cord portion, which structures an outer side belt layer which is disposed at a tire radial direction outer side of the inner side belt layer, intersects the tire equatorial plane at a second angle which is different than the first angle, and an intermediate cord portion, which is disposed between the inner side cord portion and the outer side cord portion, intersects the tire equatorial plane at an intermediate angle which is between the first angle and the second angle.
