PROBLEM TO BE SOLVED: To provide a testing method with which durability of treads of a tire can be evaluated efficiently.SOLUTION: A testing method of a pneumatic tire 4 includes a preprocessing step for obtaining a test tire by promoting deterioration of the tire 4, and a durability travel step for performing durability travel using the test tire. The preprocessing step includes a tire assembly preparation step for preparing a tire assembly 2 by integrating the tire 4 into a rim 6, and a test tire preparation step for obtaining a test tire by filling the tire assembly 2 with inert gas and then leaving the tire assembly 2 in the atmosphere of 70°C or higher and 90°C or lower for ten days or longer. |
