1. A procedure for calculating a tire contact length (6), whereby a sensor transponder (1) is fitted with at least one acceleration sensor arranged on the inner side of a running surface (2) of a tire (9), the signals from the acceleration sensor are compared with threshold values and are then integrated, and the tire contact length (6) is calculated independently of the velocity using quotient formation.
