FIELD: field.
SUBSTANCE: invention relates to rubber mixture and tyre. The invention provides improved balance if fuel economy, engagement of tyre with wet road surface and wear resistance. Rubber mixture includes caoutchouc component and silicon oxide. Caoutchouc component contains not less than 5 wt % of conjugated diene polymer, counted per 100 wt % of caoutchouc component. Conjugated diene polymer contains structural unit, obtained from conjugated diene, of the following formula 
(I) and at least one terminal group of conjugated diene polymer is modified with compounds of formulae (IIc) or (IIIa). Content of silicon oxide constitutes from 5 to 150 wt p per 100 wt p of caoutchouc component.
EFFECT: improved balance of fuel economy, adherence of tyre to wet road surface and wear resistance is provided.
