A vehicle includes a tyre monitor 400 in a wheel arch 404 that is configured to project one or more beams (typically of light) onto a tyre 300, for example at emitter 401, and measure reflections of the beams, suitably at receiver 402. Tyre monitor 400 also comprises memory and one or more processors that build a two-dimensional (2D) profile of the tyre based on the reflections, compare depths of the built profile to depths of a preloaded profile and assess tyre wear based on the comparison. An anti-theft alarm may sound based on the reflections or the lack of reflections. A preloaded profile may be selected based on tyre pressure, tyre temperature and tyre load, and the system may refrain from building a profile if a sensed moisture level exceeds a predetermined level. A search routine may be run, for example when the vehicle is parked, which may rotate the tyre in opposite directions.
