Abstract

The invention relates to a sulfur-vulcanizable rubber compound, in particular for treads of tires, which contains at least one diene rubber, liquid polybutadiene with a molecular weight of 1500-10000 g/mol and a vinyl content of 15-50%, at least one polar filler, at least one high-structure black with an iodine adsorption number of 115-200 g/kg and a DBP number of 125-160 mL/100 g and at least one glyceride and/or one factice for good abrasion characteristics, good wet traction and good traction on ice and snow with good dry braking at the same time.
