Abstract:
An aircraft tire, comprising a radial carcass reinforcement surmounted radially to the outside by a crown reinforcement and a tread, characterized in that said crown reinforcement comprises:a) at least one ply of textile reinforcement elements oriented circumferentially, the secant modulus of extension of an element being at least equal to 200 cN/tex b) at least two plies of textile reinforcement elements having ends free, which elements are parallel to each other within each ply and are crossed from one ply to the next, forming with the circumferential direction an angle &agr;, of between 5Â° and 35Â° with respect to the equatorial plane of the tire, the secant modulus of extension of an element being at least equal to 200 cN/tex, and c) radially outside of the at least two plies having textile reinforcing elements within a secant modulus of extension at least equal to 200 cN/tex, an assembly of at least two layers of textile reinforcement elements oriented relative to the circumferential direction at an angle &bgr;, of between 0Â° and 35Â° with respect to the equatorial plane of the tire, the secant modulus of extension of an element being at most equal to 200 cN/tex, and said two layers being obtained by winding a strip, formed of at least one element coated with rubber mix, from one edge of said layers to the other, the assembly of said layers having an axial width greater than the width of the tread,the widths of the plies formed of textile elements with a secant modulus of extension at least equal to 200 cN/tex being less than said width of the tread.
