Abstract
A rubber mixture, in particular for the tread of a tire, based on at least one polymer that is from the group of diene rubbers and respectively contains 5 to 100 parts by weight finely distributed, precipitated silicic acid, 0 to 80 parts by weight carbon black, if need be 0.2 to 10 parts by weight silane coupling agent, and 0.5 to 20 parts by weight of at least one non-aromatic, viscosity-reducing substance with regard to 100 parts by weight rubber. The viscosity-reducing, non-aromatic substance is based exclusively on the elements carbon, hydrogen, and oxygen and has a region with at least two hydroxyl groups that exist in the form of 1,2-diol or 1,3-diol, and a region of at least two chemically bonded carbon atoms, wherein neither the chemically bonded carbon atoms nor their chemically bonded neighboring carbon atoms are substituted with oxygen.
