1. A tire testing method conducted by a tire testing machine, the tire testing machine including a pair of spindles provided to be able to sandwich and to release a tire; a rotation mechanism provided for the paired spindles, and rotating the tire sandwiched between the paired spindles; and a drum including a moving mechanism that moves the drum in a direction of being close to or separate from the tire sandwiched between the paired spindles, pressed against the tire, and applying a load to the tire while rotating together with the tire, the tire testing method comprising: a tire sandwiching step of sandwiching the tire between the paired spindles; a tire predetermined-rotation step of controlling the rotation mechanism to drive the tire sandwiched between the paired spindles to rotate at a predetermined rotational speed lower than a specified rotational speed; a drum contact step of controlling the moving mechanism to move the drum until the drum contacts the tire rotating at the predetermined rotational speed; a tire specified-rotation step of accelerating rotation of the tire from the predetermined rotational speed to the specified rotational speed after contacting the drum with the tire; and a tire testing step of testing the tire rotating at the specified rotational speed.
