PROBLEM TO BE SOLVED: To provide a radial tire for air crafts, which reduces compression stress concentration to a carcass ply in a rim cushion section and improves the durability of the radial tire for air crafts without increasing weight. SOLUTION: With the inner pressure in a tire reduced to 10 kPa after the fitting of the tire to a standard rim, if the flange height of a standard rim R taking a bead base position X as a standard is taken as FH, and the center position of a bead core 5, the tip position of a bead filler 6, and the point where the boundary line between the body section 4a and the folding section 4b of the carcass plier 4 and a straight line which is parallel with a tire axis direction separated a distance twice as far as flange height FH on the outside in a tire radial direction from the bead base position X are intersect each other are taken as A, B and C respectively, an angle ofαformed by a straight lines AB and AC when the angle is formed on the outside of a tire width direction more than the straight line AC is set as a positive value in the range of -10°to 10°.
