Testing the rolling resistance of a tire is a common procedure in tire testing. There is a tire testing machinesuggested, comprising a rolling device, a tire mounting deviceand a driving assembly, whereby the driving assemblyis operable to rotate the rolling deviceand/or the tire mounting deviceaccording to a configurable driving cycle, whereby the rolling devicehas a drumwith an outer peripheral surface, whereby the tireis rotatable mountable on the tire mounting device, whereby the tire mounting deviceis arranged that the tireis engaged with the outer peripheral surfaceof the drum, with a first torque measuring assembly, a second torque measuring assembly, and an angular velocity measuring assembly, whereby the first torque measuring assemblyis operable to measure a drum drive torque of the drumand the second torque measuring assemblyis operable to measure a tire drive torque of the tire (), whereby the angular velocity measuring assemblyis operable to measure and/or calculate the angular velocity of the tire &#x3c9;and the angular velocity of the drum &#x3c9;.
