Crown reinforcement for a radial tire

An aircraft tire, inflated to a high pressure, comprising a tread connected to two beads by way of two sidewalls each bead having at least one annular reinforcing element a crown reinforcement and a radial carcass reinforcement comprising a number of axially inner plies A to D greater than or equal to two, which radial carcass reinforcement plies have textile reinforcing elements. Among the axially inner plies A to D, at least half the total number of axially inner plies C, D are turned up in each bead about at least one annular reinforcing element at least one and at most three of the remaining axially inner plies A, B being not turned up in any of the beads and having ends situated radially below a straight line XX&prime; parallel to the axis of rotation of the tire and passing through the radially innermost point of the cross-section of the annular reinforcing element and axially inside a straight line YY&prime;, perpendicular to the axis of rotation and passing through the center of gravity O of the cross section of the annular reinforcing element
