PROBLEM TO BE SOLVED: To obtain, in a room, a test result having high correlation with a result of a test of performance of a tire conducted outdoors.SOLUTION: An on-table testing device 1 for a tire includes a rotatable drum 2 on which a tire T is made to travel in contact, a support shaft 3 which holds the tire T mounted on a rim J rotatably in a cantilever state, and driving means of driving and rotating the drum 2 or support shaft 3, and tests performance of the tire indoors. The drum 2 has an inner peripheral surface 2G including a dummy road surface 7 on which the tire T travels. The inner peripheral surface 2G includes a smooth arcuate surface 2M which is convex outward in a drum radial direction in a section including the axis 2c of rotation of the drum. |
