An aircraft tire reinforced with a cord at a tread is provided to preclude the groove from being parted and the parted area from being scraped away by inserting first and second tread reinforcing cord layers to the width direction of the tire in the tread. An aircraft tire reinforced with a cord at a tread is composed of plural tread reinforcing cord layers formed at a tread rubber layer(10) to the width direction of a tire. The tread reinforcing cord layers contain a first tread reinforcing cord layer(71) formed to the width direction of the tire with the depth of the bottom of a groove(12), and a second tread reinforcing cord layer(72) formed to the width direction of the tire by forming a layer at the upper side of the first tread reinforcing cord layer and lowered at the bottom of the groove. The material of the tread reinforcing cord layer is a nylon-6 or a nylon-66. The interval of ends of the first and second tread reinforcing cord layers is 20~80mm.
