Wear resistance and wet grip resistance are the main properties of tires, but they are often contradictory and difficult to synergize. In this paper, drawing on the bionics concept, the bionic topography of the pits was introduced into the design of the tread rubber structure, and the synergistic improvement mechanism of the tire tread rubber with the bionic pit structures was explored. The overall performance improvement of tread compounds provided a new approach. The research showed that the designed high wear resistance tire tread compounds W2 had the best wear resistance, and the high wet grip resistance tire tread compounds S3 had the best‐wet grip resistance. When the diameter of the bionic unit was 2.5 mm and the pit number was 6, the wear resistance rate of the sample was the highest (about 11.86%), and the wear amount was 70.6; the maximum wet friction coefficient of the sample sliding on the sandpaper surface and the smooth glass surface was 0.834 and 0.71, the corresponding wet grip resistance improvement rates were also 11.89% and 12.34%, respectively. Experiments have proved that the tire tread compounds with the bionic pit structures composed of W2S3 can effectively synergistically improve wet grip resistance and wear resistance.

The materials or bionic methods available cannot further solve the contradiction between the wear resistance and wet resistance of tire tread compounds. In this study, a convex‐hull bionic tire tread compound was designed and produced according to the difference in wear resistance between two types of tire tread compounds. The effects of the bionic structure on the wear resistance and wet resistance of the tire tread compounds were explored by analyzing the changes in wear loss, wear surface characteristics, and wet friction coefficient. The wear resistance and wet resistance of the convex‐hull bionic tire tread compound were collaboratively improved. The largest increasing rate of wear resistance was 9%, and the largest increasing rates of wet sliding ability on sand paper surface and on smooth glass surface were 3.4% and 4.2%, respectively. The coupling design of materials and bionic structures offers a new way to improve the overall performances of tire tread compounds. [ABSTRACT FROM AUTHOR]
