Abstract
An aircraft tire, inflated to a high pressure, comprising a tread connected to two beads 2 by way of two sidewalls 6, each bead having at least one annular reinforcing element 3, a crown reinforcement and a radial carcass reinforcement 1 comprising a number of axially inner plies 1A to 1D greater than or equal to two, which radial carcass reinforcement plies have textile reinforcing elements. Among the axially inner plies 1A to 1D, at least half the total number of axially inner plies 1C, 1D are turned up in each bead about at least one annular reinforcing element 3, at least one and at most three of the remaining axially inner plies 1A, 1B being not turned up in any of the beads and having ends situated radially below a straight line XX′ 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 3 and axially inside a straight line YY′, perpendicular to the axis of rotation and passing through the center of gravity O of the cross section of the annular reinforcing element 3.
