Automotive shop service apparatus having means for determining the rolling resistance coefficient of a tyre

A vehicle wheel service apparatus, in particular a wheel balancer or a tyre changer, comprising a load means (26, 126) for applying a predetermined load onto a peripheral surface of a wheel/tyre assembly (14), a sensor device (30) arranged to determine forces acting between the peripheral surface of the wheel/tyre assembly (14) and the load means (26, 126), wherein the forces comprise at least a first force acting in a radial direction of the wheel/tyre assembly (14) and a second force acting in a circumferential direction of the wheel/tyre assembly (14), and an evaluation device arranged to determine a rolling resistance coefficient of the tyre (10) on the basis of the first and second forces.
