Abstract

In a method for checking vehicle tires, wheel sensor signals of at least one wheel of the vehicle are recorded over a time period, and a comparative value is determined to indicate a travel distance of the wheel. A reference travel distance covered by the vehicle in the time period is determined independently of the wheel sensor signals, and an individual ratio value of the wheel is formed from the wheel travel distance and the reference travel distance. The behavior of the ratio value over time is determined, and a determination is made concerning changes to the tire of the wheel.
