Working layer (5) comprises a circumferential zigzag winding of a strip (6) on a cylindrical surface having as its axis the axis of rotation of the tire (1), with a periodic curve (7), the peak-to-peak amplitude of which defines the axial width L of the working layer (5) between a first and a second axial end (I, I′). The working layer (5) is made up, in any meridian plane (YZ) containing the axis of rotation of the tire (1), of an arrangement of portions of strip (6) extending axially from the first axial end (I) to the second axial end (I′) of the working layer (5), such that two consecutive portions of strip (6) overlap, at least in part, over a width of overlap e. The width of overlap e between two consecutive portions of strip (6) is constant over the entire axial width L of the working layer (5).
