Abstract: Method (200), and related system (100), for monitoring a status of a tyre (99) fitted on a vehicle, the method comprising: -with the vehicle in motion and the tyre (99) in rotation, acquiring (3, 6) a motion signal representative of a motion of a crown portion (31) of the tyre (99), wherein the motion signal temporally corresponds to a plurality of turns of the tyre (99); -filtering (15, 42) from the motion signal a part of the motion signal temporally corresponding at least to each passage of the crown portion (31) in a footprint area of the tyre (99), for obtaining a filtered motion signal; -obtaining (4, 7) a frequency spectrum of the filtered motion signal; -determining (11) the status of the tyre (99) based on the frequency spectrum.
