摘要： Testing the rolling resistance of a tire is a common procedure in tire testing. There is a tire testing machine 1 suggested, comprising a rolling device 4, a tire mounting device 3 and a driving assembly 2, whereby the driving assembly 2 is operable to rotate the rolling device 4 and/or the tire mounting device 3 according to a configurable driving cycle, whereby the rolling device 4 has a drum 5 with an outer peripheral surface 7, whereby the tire 14 is rotatable mountable on the tire mounting device 3, whereby the tire mounting device 3 is arranged that the tire 14 is engaged with the outer peripheral surface 7 of the drum 5, with a first torque measuring assembly 12, a second torque measuring assembly 18, and an angular velocity measuring assembly 12, whereby the first torque measuring assembly 12 is operable to measure a drum drive torque of the drum 5 and the second torque measuring assembly 18 is operable to measure a tire drive torque of the tire (14), whereby the angular velocity measuring assembly 12 is operable to measure and/or calculate the angular velocity of the tire ωT and the angular velocity of the drum ωD.
