Rolling resistance (RR)

wet skid resistance (WSR) and wear resistance (WR) are the most important properties for the tires

while they are conflicting criteria in designing the tire tread composites

and so improving the above three properties at the same time is still a challenge to the tread composites. In this paper

from the viewpoint of viscoelasticity of the rubber composites

the effects of filler network structure and filler-rubber interaction on RR

WSR and WR and their mechanism are reviewed. By the methods of rubber molecule structure optimization and filler modification

decreasing the filler network structure and enhancing the filler-rubber interaction can improve the overall performance of the tire tread composites.
