A method for determining a tire tread depth during operation of a vehicle includes determining an instantaneous rotational speed of a vehicle wheel having the tire based on data determined by at least one first sensor, then determining a vehicle speed based on data determined by at least one different second sensor, then determining an instantaneous dynamic wheel radius based on the determined instantaneous rotational speed and the determined instantaneous speed. At least one first tire parameter selected from an instantaneous tire temperature, tire pressure and tire load is determined. An instantaneous dynamic inner wheel radius is determined based on the at least one determined first parameter, wherein the inner wheel radius is the distance between the center of the wheel and the tire-side start or seam of the tread. A tire tread depth is determined based on the determined instantaneous dynamic radius and the determined instantaneous dynamic inner radius. |
