摘要： The present invention provides a belt formed of a spirally wound strip member constituted of a few juxtaposed cords and rubber coating thereon, with a structure which can absorb influence of difference in winding diameter at the unit width portion of the strip member without deteriorating productivity of the tire. Specifically, the present invention provides a radial tire for use in aircraft, having a carcass including at least one layer of carcass ply extending in a troidal shape between a pair of bead cores, at least two layers of belt formed by spirally winding in a tire circumferential direction a strip member constituted of plural juxtaposed cords and rubber coating thereon, on the carcass on the outer side in the tire radial direction at a crown region of the carcass, and a tread rubber laminated on the belt, characterized in that: thickness and circumference of the belt decrease from the tire equatorial face toward end portions thereof in the widthwise direction; at least a belt portion corresponding to a tire shoulder portion, a boundary face between the belt layers and the tread rubber has a stepped configuration descending in the tire radial direction from the tire equatorial face toward the end portions thereof in the widthwise direction; and a boundary face between the belt and the carcass is a smooth curved face.

摘要： In the pneumatic radial tire of the present invention, a total strength K0 of a belt layer 20 in a circumferential direction of the tire per unit of width at a tire equator surface position P0 is set greater than a total strength of the belt layer 20 in the circumferential direction of the tire per unit of width at a width position P2 corresponding to ⅔ of a maximum width of the belt layer having the tire equator surface CL as a center. In this way, it is possible to suppress the quantity consume of material in the belt layer 20, and to suppress the amount of expansion of tread rubber in a tread central region in the circumferential direction thereof when a standard internal pressure is charged and when the tire is rotated at high speed, thereby suppressing the growth of tire diameter. Since the expansion amount of the tread rubber in the circumferential direction is suppressed, the tension of the rubber is reduced. Therefore, it is possible to increase the resistance of the tread against the sticking of foreign matter, and even when foreign matter sticks in the tread, it is possible to suppress the growth of the crack.
摘要翻译：在本发明的充气子午线轮胎中，轮胎赤道面位置P 0处的每单位宽度的轮胎周向上的带束层20的总强度K 0被设定为大于带束层的总强度在轮胎赤道面CL为中心的带束层的最大宽度的2/3的宽度位置P 2处，在每单位宽度的轮胎的圆周方向上。以这种方式，可以抑制带束层20中的材料的消耗量，并且当标准内部压力被充电时，抑制胎面中心区域中的胎面中心区域中的胎面橡胶的膨胀量，轮胎高速旋转，从而抑制轮胎直径的增长。由于胎面橡胶在周向上的膨胀量被抑制，所以橡胶的张力降低。因此，可以增加胎面抵抗异物粘附的阻力，并且即使当异物粘在胎面中时，也可以抑制裂纹的生长。
