Sulfur-vulcanizable rubber mixture without aromatic process oils, in particular for the tread rubber of vehicle pneumatic tires, containing at least one diene rubber, carbon black, mineral oil plasticizer, and resin. A vehicle pneumatic tire with a tread rubber that is composed at least partially of a rubber mixture of this type vulcanized with sulfur is also disclosed. To improve the chipping and chunking behavior, the rubber mixture can contain at least one diene rubber, 5-100 phr of at least one carbon black with an iodine adsorption number of 100-180 g/kg and a DBP number of 100-150 cm/100 g, 5-80 phr of at least one mineral oil plasticizer that has a content of polycyclic aromatic compounds determined with the DMSO extract according to the IP 346 method of less than 3% by weight relative to the total weight of the mineral oil plasticizer, and 5-30 phr of at least one resin with an average molecular weight determined with GPC of less than 400 g/mol and a softening point (ring and ball according to ASTM E 28) of less than 40&#xb0; C.

Rubber mixture and tires

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.
