FIELD: chemistry.
SUBSTANCE: mixture contains a rubber component which contains a natural rubber component consisting of at least either natural rubber or epoxidated natural rubber. The mixture also contains inorganic filler containing at least silicon dioxide. Content of said inorganic filler ranges from 50 pts.wt to 80 pts.wt per 100 pts.wt said rubber component when the rubber mixture is used to obtain rubber for the clinch, and from 60 pts.wt to 100 pts.wt per 100 pts.wt said rubber component when the rubber mixture is used to obtain rubber for the sidewall filler. Content of soot in the rubber mixture ranges from 2 pts.wt to 5 pts.wt pr 100 pts.wt said rubber component. If the rubber mixture is used for the sidewall filler, the inorganic filler contains silicon dioxide and clay, the amount of clay in the mixture being equal to 5-40 pts.wt per 100 pts.wt rubber component and the total amount of silicon dioxide and clay is at least 65 pts.wt per 100 pts.wt rubber component. The result is reducing the amount of materials derived from oil resources when producing the rubber mixture.
EFFECT: improved operational characteristics.
