Abstract
An aircraft tire, having a radial carcass reinforcement surmounted radially to the outside by a crown reinforcement and a tread, said crown reinforcement including:a) at least one ply of reinforcement elements of high modulus oriented circumferentially,b) two plies having ends free of reinforcement elements of high modulus, which 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 5° and 35°, andc) radially to the outside, an assembly of at least two layers of textile elements of low modulus which are oriented relative to the circumferential direction at an angle &bgr;, of between 0° and 35°, said two layers being obtained by winding in a zigzag a strip, formed of at least one coated cable, and the assembly of the layers having an axial width greater than the width of the tread, whereas the widths of the textile plies of high modulus are less than said width of the tread.
