摘要： System for determining tire wear for tires (11, 12, 13, 14) of a wheeled motor vehicle (10), comprising: a direct tire pressure determination unit (17) being configured to measure at least the tire pressure of the tires (11, 12, 13, 14); an indirect tire pressure determination unit (19) being configured to determine for at least some of the tires (11, 12, 13, 14) a roll radius factor corresponding to or depending from the roll radius of the respective tire; a tire force determination unit (21) being configured to determine a vertical force factor corresponding to or depending from a vertical force applied to the tires (11, 12, 13, 14); a processing unit (23) determining the tire wear for such tires (11, 12, 13, 14) of the motor vehicle for which the indirect tire pressure determination unit (19) provides the respective roll radius factor, namely by compensating the roll radius factor of the tires (11, 12, 13, 14) provided by the indirect tire pressure determination unit (19) on basis of the tire pressures of the respective tires provided by direct tire pressure determination unit (17) and of basis of the vertical force factor of the respective tires provided by the tire force determination unit (21) thereby providing a compensated roll radius factor for the respective tire (11, 12, 13, 14), and by comparing the compensated roll radius factor for the respective tire with a reference roll radius factor in such a way that the difference between the compensated roll radius factor and the reference roll radius factor of the respective tire provides the tire wear of the respective tire (11, 12, 13, 14).
