Abstract
An applied load acting on a tire is varied by alternately moving a load drum in a direction of approaching and leaving the tire. A phase difference between a variation of a position of the load drum and a variation of the applied load is calculated. A tire having an abnormality in rolling resistance is sorted out based on the calculated phase difference.
