Zusammenfassung:PROBLEM TO BE SOLVED: To provide a crown reinforcing member of a tire for an aircraft in which durability can be especially improved. SOLUTION: A tire for an aircraft has a radial carcass reinforcing member and a crown reinforcing member 2 mounted on the radial carcass reinforcing member. The crown reinforcing member 2 comprises at least three fabric reinforcing elements including at least one twin plies 21 composed of two plies 10 'guided' at an angle NTα deg.. The crown reinforcing member 2 has a non- connected intermediate layer 22 between at least one twin plies 21 and other guided plies 10. The intermediate layer 22 has a thickness E necessary for forming a radial distance of at least 1.0mm between a radially inner ply and a radially outer cord which surrounds the intermediate layer and is formed with the fabric reinforcing element covered with a rubber mixture with a second elongation factor of 5 to 9Mpa which is measured with relative elongation between 0.06 and 0.2.
