Abstract: The present invention relates to a sensor as well as a measuring device with a sensor of this type for contactlessly detecting the change in position of a measuring point on or in a tire on the basis of a force acting on the tire of a wheel, in particular during driving, wherein the sensor is fixed in a stationary position in relation to the rim of the wheel. So as to be able to measure, in a simple manner, the transversal and longitudinal forces acting on the tire during driving, the sensor detects the change in position of the measuring point in the longitudinal or transverse direction (y,x) in relation to the running surface of the tire.
