The object of the invention is to develop rubber mixtures for tyre treads which have improved wet grip and balanced abrasion and rolling-resistance properties. This is achieved by the rubber blends according to the invention, which contain 3,4-polyisoprene with a 3,4-content of from 55 to 75 %, a glass transition temperature of from 0 to -25 DEG C, a molecular weight (Mn) of 200,000 or more, and a nonuniformity (U) of less than 1.8. …<??>Motor vehicle tyres, in particular, can be advantageously equipped with the rubber mixture according to the invention. |
