PURPOSE:To obtain a composition showing excellent effects in both ice and snow performances and not raising dust even by using the composition as rubber chain, comprising diene-based rubber, silica, carbon black and ground plant. CONSTITUTION:A composition comprising at least one of diene-based rubber, silica and carbon black, having an extracted content E pts.wt. based on 100 pts.wt. rubber content after extraction of vulcanized rubber with acetone chloroform satisfying the formula E<0.4(A-38) (A is sum of carbon black pts.wt. and 1/2 silica pts.wt. based on 100 pts.wt. rubber after extraction of vulcanized rubber with acetone chloroform) and using 3-50 pts.wt. based on 100 pts.wt. rubber component after the extraction of ground material of plant having 0.01-5mm average particle diameter is used as a rubber composition of part of rubber chain, which is attached to the outer periphery of automobile tires in use, made of rubber and brought into contact with a road surface to prevent sliding of automobile tires. |
