Abstract

A method used for determining a profile depth or wear on a tread of a tire of a vehicle, and/or a tire characteristic, a magnetic field being detected by a magnetic field sensor disposed in the interior of the tire, particularly in the area of the tread on the tire interior, or at a distance from the tire, particularly in the area of a wheel housing or a wheel well of the vehicle, the magnetic field being transmitted or changed by at least one indicator element disposed in the tread on the tire exterior. The current wear state of the tread and/or the tire characteristic, particularly a tire type and/or permissible top speed, is determined based on output signals of the magnetic field sensor. The invention further relates to tires.
