FIELD: chemistry.
SUBSTANCE: invention relates to a rubber mixture for making a pneumatic tyre. The pneumatic tyre is provided with sidewall filler consisting of a rubber mixture which contains a rubber component, at least one resin selected from terpene-based resin and a colophony-based resin in amount of 0.5-15 pts.wt, 60-120 pts.wt silicon dioxide, 5 pts.wt or less soot and 0.1-0.8 pts.wt peptising agent per 100 pts.wt said rubber component. The pneumatic tyre is additionally provided with clinch part rubber consisting of a rubber mixture which contains a rubber component, at least one resin selected from terpene-based resin and colophony-based resin in amount of 0.5-20 pts.wt and 35-150 pts.wt silicon dioxide per 100 pts.wt said rubber component. The rubber component consists of a natural rubber component consisting of at least one rubber selected from natural rubber and epoxidated natural rubber.
EFFECT: pneumatic tyre is made from rubber mixtures in which materials obtained from oil resources are used in a lesser amount and provide properties required for the desired application and have improved processability.
