FIELD: chemistry.
SUBSTANCE: invention relates to rubber mixture, method for thereof obtaining and to tyre. Rubber mixture includes caoutchouc component, containing polybutadiene and non-mixable with polybutadiene diene or olefin caoutchouc, as well as filling agent. Mooney viscosity (ML1+4/100°C) of polybutadiene, designated as ML(I), and Mooney viscosity (ML1+4/100°C) of non-mixable with polybutadiene diene or olefin caoutchouc, designated as ML(II), satisfies ratio ML(I)≥ML(II). Ratio of weight content of polybutadiene and weight content of non-mixable diene or olefin caoutchouc is in the range from 45/55 to 55/45.
EFFECT: rubber mixture is characterised by excellent resistance to destruction and provides good processability without reduction of tyre wear resistance and makes it possible to reduce rolling resistance.
