ABSTRACT:
A rubber mixture vulcanizable with sulphur, a tire tread manufactured from it and also tires with a vulcanized tread are proposed. The rubber mixture contains in each case 100 parts by weight of elastomers, 20 to 80 parts by weight of a copolymer of conjugated diene and vinyl aromatic compound with very low long chain branching manufactured by solution polymerization in a hydrocarbon solvent, 10 to 50 parts by weight of polybutadiene with very low long chain branching, 10 to 30 parts by weight of polyisoprene with a 3,4 bond content of 50 to 70% by weight and 30 to 100 parts by weight of silica as filler material. Through the special combination of the three elastomers with silica as a filler material one obtains an easily processable mixture which leads to vulcanized tire treads with improved grip on wet and dry surfaces.
