Abstract
A method for ascertaining the pressure and the profile depth in a pneumatic vehicle tire which is fitted to a vehicle, wherein the pressure is detected with the aid of an arrangement comprising load sensors, which arrangement supplies force signals for a two-dimensional pattern of the force distribution which is exerted by the vehicle tire in contact with the sensors when the vehicle moves over the arrangement, wherein the tire pressure is determined from the force distribution independently of the method of manufacture or the model of the tire and of the vehicle, is characterized in that the profile depth of the tire is determined before, while or after the pressure is determined.

20. A method for the determination of the pressure and the profile depth of a pneumatic vehicle tire which is installed on a vehicle, whereby:
the pressure is determined by means of an array of load sensors which supply force signals for a two-dimensional pattern of the fore distribution which is exerted by the vehicle tires in contact with the sensors when the vehicle moves over the array, whereby the tire pressure is determined from the distribution of force independently of the type of manufacture or the model of the tire and of the vehicle, wherein before, during or after the determination of the pressure, the profile depth of the tire is determined by triangulation, whereby the triangulation is used on unloaded profile sections of the tire, and for this purpose the angle of incidence of a measurement beam striking the unloaded tire profile is an angle of less than 90°
