A method and apparatus for determining the condition of a tire tread of a vehicle wheel including a rim and a tire configured to perform the steps of: (1) emitting an electromagnetic radiation towards the tread of the tire, (2) receiving a reflected electromagnetic radiation from said tread of the tire in response to the emitted radiation, (3) processing the reflected radiation to obtain height data including respective heights of a plurality of points located on the tread of the tire, (4) repeating the steps (1) to (3) in successive time intervals within which the vehicle wheel has driven a predetermined distance, and storing the respective height data, particularly average values of the height data, each in dependence of the driven distance, and (5) deriving from the succession of the stored height data a residual mileage of the tire. |
