Claim:
1. A tire testing machine that tests a tire on which identifying information is installed, the tire testing machine comprising: a test station in which spindles to attach the tire are provided; a conveyor that feeds the tire into a center position of the spindles; a tire rotation device arranged in said conveyor on the upstream side in the conveying direction of said test station, the tire rotation device that rotates the tire; an identifying information detection sensor arranged in said conveyor on the upstream side in the conveying direction of said test station, the identifying information detection sensor that detects the identifying information installed on the tire which is rotated by said tire rotation device; and a control unit that detects the identifying information on the tire which is being rotated by said tire rotation device, by means of said identifying information detection sensor, calculates a rotation angle of the tire which is being rotated by said tire rotation device, relative to the direction connecting a position of the detected identifying information and the center of the tire, monitors a position of the identifying information of the tire which is being rotated by said tire rotation device, and further, when the calculated rotation angle of the tire becomes a target stopping angle designated in advance, stops rotation of the tire.
