PURPOSE:To increase the shock buffering effect of an airplane at its landing and takeoff by arranging each cord of a carcass and a belt layer for the equatorial surface of a tire at a specific angle and forming each cord with the organic fiber cord with the specific pulling modulus of elasticity. CONSTITUTION:A tire T for an airplane consists of a carcass that is composed of two carcass plies 2 and 3 obtained by folding and hooking the end on the circumference of the bead core 1 from the inside to the outside and a carcass ply 4 obtained by folding and hooking the end on the circumference of the bead core 1 from the outside to the inside, belt layer 5 made of organic fiber cords arranged at the outside of the crown section of the carcass, and the band 8. In addition, the cord of the carcasses 2-4 and the belt layer 5 is formed with the organic fiber cord having the pulling modulus of elasticity of less than 5,000kg/ mm.<2> and desirably of less than 1,000kg/mm.<2>. Furthermore, the cord of the carcasses 2-4 is arranged 60-90 deg. for the circumferential direction of the tire and the cord of the belt layer 5 is arranged less than 30 deg. for the circumferential direction of the tire. |
