A system comprising at least one sensing system embedded inside a vehicle tyre with means to connect or interface with external electronics capable of calculating or interpolating the amount of wear on the tyre tread. The sensing parts capacitance, resistance, impedance, inductance and/or continuity may be affected by the depth of tread. The sensing part may comprise a foil or wire embedded in the tyre, protruding into at least one tread block such that electrical continuity is interrupted when tyre wear reaches a certain threshold. The sensing part may comprise two conductive plates separated by an insulating layer to form a capacitor. The sensing part may comprise at least one coil, the inductance of which can be measured. The sensing part may comprise a material or compound with magnetic properties.
