FIELD: chemistry.
SUBSTANCE: invention relates to field of technical rubber products and can be used for manufacturing pneumatic tyres. Rubber mixture contains rubber component and silicon dioxide, containing water, in which "CTAB" (m2/g) as specific surface in adsorption of cetyltrimethylammoniumbromide and "IB" as index of micropores in form of ink bottle in water-containing silicon dioxide satisfies certain dependence, and "loss on ignition" (wt %) as weight loss, when silicate-hydrate is heated at 750°C for 3 hours, and "loss on heating" (wt %) as weight loss, when silicate-hydrate is heated at 105°C for 2 hours, satisfy certain dependence.
EFFECT: invention provides rubber mixture, capable of reaching good properties of rolling resistance and good wear resistance simultaneously when rubber mixture is applied on constituting element, for instance tyre tread.
