摘要： This invention improves the precision and reliability with which rolling resistance can be measured. This rolling-resistance testing method includes a rolling-resistance measurement stage and a determination stage. In the rolling-resistance measurement stage, a component force meter is used to measure the tangential axial force that occurs in a tire axle when the tire is rotated under load. In the determination stage, the axial force is measured in a no-load stopped state in which the tire has been separated from a drum, said axial force is compared to a threshold, and if the axial force is greater than said threshold, a determination that an anomaly has occurred in the test is made.
