A tire testing device which can improve reliability in measurement of loss in tire is provided. The tire testing device can include a tire motor connected with the rotational shaft of the tire, a tire shaft torque meter for detecting torque applied to the rotational shaft of the tire, a roller on to which the tire is pressed to be contact with, a roller motor connected with the rotational shaft of the roller, and a roller shaft torque meter for detecting the torque applied to the rotational shaft of the roller. The device measures loss of power in tire from the difference in power of the tire obtained by adding the torque measured by the tire shaft torque meter and the difference in power of the roller obtained by adding the torque measured by the roller shaft torque meter.
