1. A method of manufacturing a tire, comprising the steps of:
forming a reinforcing structure by laying a plurality of strips of a first layer and a plurality of strips of a second layer side by side in a main direction of laying, spacing the strips of the first layer apart by a distance that is less than a width L of the strips of the second layer and in such a way that edges of the strips of the first layer overlap edges of the strips of the second layer, and wherein the first layer of strips is separated by the second layer of strips by a layer of uncoupling rubber, the reinforcing structure further including an external layer of rubber and an internal layer of rubber, and wherein the layer of uncoupling rubber and the external layer of rubber and the internal layer of rubber are all of materials that are pervious to air; and
building the tire with the reinforcing structure and without an innermost rubber layer that has airtightness properties.
