Abstract

A caoutchouc mixture vulcanisable with sulphur, tyre treads manufactured therefrom and also tyres with a vulcanised tread are proposed. The caoutchouc mixture contains 30 to 100 parts by weight of isoprene-butadiene-styrene terpolymer with a glass transition temperature range between -90.degree. C. and 20.degree. C., 0 to 70 parts by weight of one or more further elastomers, 20 to 90 parts by weight of silica as filler material, customary additives and also a vulcanisation system. This caoutchouc mixture delivers tyre treads with good resistance to abrasion and a low loss factor which is correlated with a low running resistance.
