PROBLEM TO BE SOLVED: To provide a tire running test method and a tire running testing apparatus for evaluating the fault of a tire by testing precisely with a small number of error detections. SOLUTION: The tire running testing apparatus 10 comprises a tire support section 28 for rotatably supporting the tire 20; a drum 26 for running the tire 20 by bringing a tread section 20T of the tire 20 into contact with a drum surface; a motor 29 for rotating the drum 26; a radiation thermometer 14 for measuring the temperature of the tread section 20T without any contact; and a computer 32 for detecting the local temperature increase section of the tread section 20T, based on measurement results by the radiation thermometer 14. The computer 32 stops the running of the tire after prescribed time, when it detects a local temperature increase section on the tread section 20T. Even if the occurrence of the local temperature increase section is detected, a part in which chunks, separation, or the like is generated can be expanded by continuing the running of the tire for a prescribed amount of time.
