PROBLEM TO BE SOLVED: To obtain more stable test data by suppressing temperature variations of a drum surface and the controlling the temperature of a road surface, independently of a room-temperature, in a tire testing apparatus. SOLUTION: The tire testing apparatus includes a cylindrical drum 10 including a pseudo-travel road surface 16 on an inner circumference; a rotary driving means 20 for rotating and driving the cylindrical drum 10; a tire rotary holding means 30 for holding the tire T relative to the pseudo travel road surface 16 of the cylindrical drum 10 for rotating the tire T; and a temperature control means 40, provided inside the pseudo travel road surface 16 for changing the temperature of the pseudo travel road surface. The temperature control means 40 performs temperature control by making a temperature control fluid to flow. COPYRIGHT: (C)2011,JPO&INPIT |
