As for the performance evaluation of winter tires, in general, stable evaluation in the room is desired because the vehicle test is affected by the weather and the evaluation period is limited. In addition, since rubber materials and tire characteristics depend on temperature, temperature is one of the very important factors to obtain high reliable results in tire evaluation, and it can be said that it depends on how it can be tested under constant temperature conditions. We will introduce the general ice performance evaluation technology of winter tires by the indoor vehicle test, indoor drum test method, and lab evaluation technology.
