PROBLEM TO BE SOLVED: To provide a tire running test apparatus which allows a suited support liquid to be supplied thereto both in high speed and in low speed by properly switching a liquid supplying means, even though a supply device for the support liquid is very compact, and allows the performance of a tire to be measured surely, while reducing the abrasion of a load supporter and/or a belt. SOLUTION: This tire running test apparatus 1 comprises a driving drum 4, a driven drum 5, a belt 6 laid between the two drums, the load supporter 7 supporting the belt 6 by its flat surface from the back side thereof, and the liquid supplying means 10 provided on the load supporter 7 and supplying the support liquid to between the load supporter 7 and the belt 6, with the support liquid supporting the belt 6 from below. The load supporter 7 is divided into a tire upstream part U, a tire 2 contact part, and a tire downstream part D, along the traveling direction of the belt 6. The supply means 10 is structured so that the liquid supplying state of the support liquid can be changed independently for each of the upstream part U, the contact part 2, and the downstream part D.
