With the continuous improvement of the average speed level of the automobile, users have higher requirements on the wheel adhesion capacity and the drainage performance of the automobile in special weather conditions such as rainy days. Two dangerous situations with small adhesive capacity can be encountered when the automobile runs in rainy days: in one case, when rain begins and only a small amount of rain is present on the road surface, the rain mixes with dust and oil on the road to form a high-viscosity water solution, and the rolling tire cannot extrude the water solution film between the tread and the road surface, so that the adhesion performance is greatly reduced. In another situation, when a vehicle running at high speed passes through a road surface with a water accumulation layer, the phenomenon of water slip occurs; when a high-speed running automobile passes through a road surface with a water accumulation layer and the lifting force of the hydrodynamic pressure under the tread is equal to a vertical load at a certain automobile speed, the tire completely floats on a water film and is not in contact with the road surface, the braking is invalid, and the water slipping phenomenon is generated to cause the out-of-control of the automobile.
