Rubber composition for vehicle tyretread

摘要

A sulphur-crosslinkable rubber mixture (I) for the production of treads, especially for winter tyres, containing (a) 20-100 phr cis-1,4-polyisoprene, (b) 0-65 phr polybutadiene with a cis content of more than 90 mol%, (c) 0-65 phr solution- polymerised styrene-butadiene copolymer and (d) 65-120 phr silica (phr = pts. wt. per 100 pts. wt. total rubber). Also claimed are vehicle tyres with a tread made from mixture (I).
