FIELD: chemistry.
SUBSTANCE: rubber mixture contains, at least, the following constituents: 40 to 100 parts of, at least, one natural and/or synthetic polyisoprene per 100 parts of rubber, 15 parts or more of, at least, one hydrocarbon resin per 100 parts of rubber formed from 50 to 100 wt % of the aliphatic monomers C5 and from 0 to 50 wt % of, at least, one additional monomer, wherein the hydrocarbon resin has a value of Q from 0.015 to 0.050[°C⋅mol/g], where Q=softening point [°C]/determined by centrifugation with an average Mc [g/mol], and wherein the hydrocarbon resin has a softening point in accordance with ASTM E 28 (ring and ball method) from 60 to 200°C, and 10-300 parts of, at least, one silicic acid per 100 parts of rubber.
EFFECT: rubber mixture has a high level of performance in terms of rolling resistance and wet grip performance.
