Method for manufacturing an optimized layer of self-sealing product

A method for manufacturing a tire comprising a tread, an airtight internal layer, and at least one layer of a self-sealing product extending circumferentially radially on an inside of part of the airtight internal layer, the method comprising:

• winding a strip or a bead of a self-sealing product through multiple circumferential turns radially on an inside of the airtight internal layer of the tire, which does not include the layer of self-sealing product yet, and at least partially in line with the tread, the winding the strip or the bead being carried out according to a winding law for winding circumferential turns of the strip or of the bead,
• wherein, while winding the strip or the bead of self-sealing product, one or more parameters of the winding law making it possible to axially vary a thickness of the layer of self-sealing product are varied over at least 50% of a circumferential length of the layer of self-sealing product,
• wherein the strip or the bead is wound on itself through Nai>1 radially superposed circumferential turns over L≥1 axial portions of the layer of self-sealing product, with i ranging from 1 to L, and
• wherein the strip or the bead is wound on itself through Nbj>1 radially superposed circumferential turns or the strip or the bead is wound through Nbj=1 circumferential turn over M≥1 axial portions of the layer of self-sealing product, with j ranging from 1 to M.
