Abstract
The manufacturing method makes it possible to manufacture a tire () comprising: a tread (), an airtight internal layer (), and at least one layer of a self-sealing product () extending circumferentially radially on the inside of part of the airtight internal layer (). During the method, a strip or a bead () of a self-sealing product is wound through multiple circumferential turns (Nai, Nbj) radially on the inside of the airtight layer () of the tire, which does not have the layer of self-sealing product () yet, and at least partially in line with the tread (). The winding step is carried out according to a law for winding the strip or the bead () in circumferential turns. During the winding step, at least one parameter of the winding law making it possible to axially vary the thickness of the layer of self-sealing product () is varied.
