Method of applying a layer of material (25, 26) to the inner wall of a cycle tyre (20) in the form of a torus, with an inner wall (28) and an outer wall (29) and having a crown (22) extended by two sidewalls (21), two beads (23a, 23b) and two bead wires (30a, 30b) placed in said beads, said tyre having a given nominal inflation pressure, which comprises the following steps: the tyre (20) is turned inside-out so as to bring the inner wall (28) to the outside of the torus and the outer wall (29) to the inside of the torus; the outer torus wall (29) of the tyre is extended by applying an internal inflation pressure to said outer wall (29) above the nominal inflation pressure of said tyre; the layer of material (25, 26) is applied to the inner wall (28) of the tyre (20); and the tyre (20) is turned inside-out so as to bring the inner wall (28) and the outer wall (29) back into their initial positions.
