A method for determining the tread depth of a vehicle tire, with the tire being mounted on a vehicle, the tire being rolled over or placed on a measuring station, the tread of the tire being optically sensed transversely to the rolling direction of the tire on at least one measuring line, a ray fan extending from a light source being reflected at the tire surface and a signal of the reflected ray fan being recorded by a sensor, and the signal of the reflected ray fan being evaluated by way of a triangulation method, is characterized in that the signal is recorded in a non-orthogonal manner to the tire surface. |
