A method for determining a maximum adhesion limit between a tire and a substrate on which the tire is running in a longitudinal direction. The method includes detecting an instantaneous slip of the tire; detecting an instantaneous longitudinal force on the tire; determining an instantaneous coefficient of adhesion; forming a tuple from the detected slip and determined instantaneous coefficient of adhesion; and determining the adhesion limit. The adhesion limit is determined on the basis of the slope of a straight line passing through the origin and the tuple, if the slip is less than a first threshold value, or on the basis of the slope of a tangent passing through the tuple, if the slip is between the first threshold value and a second threshold value, or directly on the basis of the instantaneous coefficient of adhesion, if the slip is greater than the second threshold value.
