The invention relates to a method and an apparatus for determination of the wear on at least one tire of a vehicle, wherein the vehicle has a tire pressure monitoring system, consisting of a pressure sensor, a transmission unit and a reception unit, as well as a computer unit and a data memory having a database. Proceeding from a circumference of the tire (5) defined by the tire manufacturer and thereby a mantle surface having a length L=2πr, wherein r is the radius of the tire (5), the radius decreases during corresponding wear, and thereby the length of the mantle surface also decreases. The length of the flat pattern of a new tire is therefore greater, in terms of length, than the length of the flat pattern of a used tire. This is determined by a sensor (4), the value of which is transmitted by a first module (2) to a second module (3), which is fixed in place. There, the value L is calculated and compared with data in a database and evaluated.
