Abstract
A caoutchouc mixture vulcanisable with sulphur, tire treads manufactured therefrom and also tires with these vulcanised tire treads are proposed. The caoutchouc mixture contains 30 to 100 parts by weight of isoprene-butadiene copolymer, 0 to 70 parts by weight of one or more further elastomers, 20 to 90 parts by weight of silica as a filler material, customary additives and also a vulcanisation system, with all parts by weight being related to 100 parts by weight of total elastomers. This caoutchouc mixture delivers tire treads with good resistance to abrasion and a low loss factor which is correlated with a low rolling resistance.
