A tyre monitoring apparatus comprising a monitor installed on a tyre and a pulse width measuring apparatus for measuring the width of pulses produced by the monitor. The pulse width measuring apparatus comprises a frequency analyzer for producing a frequency representation of the pulse, a signal processor for determining a minimum value of the frequency representation, and a pulse width estimator that inverts the minimum value to produce a measurement for the pulse width. The tyre monitoring apparatus uses the pulse width measurement as an indication of characteristics of the tyre.
