PROBLEM TO BE SOLVED: To provide a radial tire for an aircraft making high strength and excellent anti-fatigue compatible. SOLUTION: The radial tire for the aircraft has a pair of bead parts, a pair of sidewall parts and a tread part continued to both the sidewall parts, and is provided with a carcass troidally extending between the pair of bead parts and reinforcing the respective parts. In the radial tire for the aircraft, a polyketone fiber cord is used for a ply of the carcass, and lower twisting coefficient and upper twisting coefficient of the cord are different from each other. Here, the lower twisting coefficient is preferably in a range of 0.30-0.70 and the upper twisting coefficient is preferably in a range of 0.30-0.70. COPYRIGHT: (C)2010,JPO&INPIT
