Abstract

A method for determining the load exerted on the tire of a motor vehicle or to monitor the tire pressure, wherein during operation of the vehicle the pressure in the individual wheels is detected and the rotational behavior of the individual wheels is monitored, and wherein load distribution characteristic quantities are determined by comparing the rotational behavior or changes in said rotational behavior of the individual wheels during given driving conditions taking onto account preset or learned variables. Ultimately, the load exerted on the tires or pressure loss is determined from the tire pressure and the load distribution characteristic quantities.
