RUBBER COMPOSITION OF STUDLESS TIRE TREAD

摘要

A studless tire tread rubber composition is provided to increase traction of a studless tire tread on a snowy road and enhance safety during driving. A studless tire tread rubber composition includes 100 parts by weight of rubbers, and 1-20 parts by weight of an olive kernel powder, 1-20 parts by weight of a longan shell powder, or 1-15 parts by weight of a mixture of the olive kernel powder and longan shell powder as an additive. The additive has an average diameter of 40-850 micron. The additive forms small and rough shapes on a tread surface to increase the coefficient of friction between a studless tire tread and a snowy road.
