1. A method for cleaning an inner surface of a tire, comprising:
emitting a laser beam that is directed against the inner surface via at least an emitter device;
performing a first cleaning within at least a first annular zone of the inner surface in applying, via at least the laser beam, to the first annular zone a first surface energy density; and
performing a second cleaning within at least a second annular zone of the inner surface in applying, via at least the laser beam, to the second annular zone a second surface energy density that is not zero and that is lower than the first surface energy density,
wherein a different respective surface energy density is applied via at least the laser beam to each of the first annular zone and the second annular zone.
