Abstract
In a method for monitoring tire air pressure of the wheels of an automobile, longitudinal force of the tires-slip test data pairs are measured and recorded for at least one wheel, while the automobile is being driven. A corresponding evaluation unit determines a compensation curve for the recorded longitudinal force of the tires-slip test data pairs, along with an associated offset value based on a zero point in a longitudinal force of the tires-slip performance graph. From the offset value, the respective wheel radius relationship between at least one driven and one non-driven wheel can be calculated, and from this the relative tire pressure of the wheels can be determined.
