The invention relates to a sulfur-crosslinkable rubber compound, in particular for treads of vehicle tires, and a vehicle tire. The rubber mixture contains: 10 to 30 phr of at least one natural and / or synthetic polyisoprene and From 70 to 90 phr of at least one styrene-butadiene rubber and / or polybutadiene and At least one polyethylene having a density according to ASTM D 1505 of 0.915 to 0.935 g / cm 3 and a weight average molecular weight distribution Mw according to GPC of 20,000 to 500,000 g / mol. A vehicle tire comprising the rubber mixture according to the invention in at least one component, preferably in the tread, exhibits improved abrasion behavior and a lower and thus improved rolling resistance as well as improved resistance to cracks, in particular against damage to the tread profile under high load. |
