FIELD: chemistry.
SUBSTANCE: invention relates to a rubber mixture for tyres and a studless tyre for a passenger vehicle. The rubber mixture for tyres includes a rubber component and finely ground silicon dioxide, where the rubber component contains modified natural rubber with phosphorus content of 200 ppm or less and butadiene rubber. The finely ground silicon dioxide has CTAB specific surface area of 180 to 600 m2/g and BET specific surface area of 185 to 600 m2/g. For 100 wt % of the rubber component, the amount of the modified natural rubber is 50 to 80 wt % and the amount of butadiene rubber is 20 to 50 wt %.
EFFECT: invention provides well balanced improvement of fuel saving, wear resistance and movement characteristics on an ice-covered and snow-covered road.
