FIELD: chemistry; automotive industry.
SUBSTANCE: invention relates to a rubber composition for a tire tread, a method for manufacturing it, as well as a non-studded tire. Said rubber composition contains a diene rubber, from 1 to 20 weight parts of a rolled silicon rubber compound, from 0.2 to 20 weight parts of thermally expandable microcapsules and from 10 to 100 parts by weight of fillers containing silica and carbon black, per 100 parts by weight of diene rubber. Also, the composition contains from 3 to 15 % by weight of a silane coupling agent relative to the total amount of silica introduced into the vulcanized rubber composition. In this case, the rolled silicon rubber compound contains silica, and the hardness of the rubber of the rolled silicon rubber compound is from 10 to 50.
EFFECT: invention provides improved friction characteristics of tires on ice, surpassing conventional performance.
