FIELD: chemistry.
SUBSTANCE: invention relates to a rubber mixture and a tyre. The rubber mixture includes sulphur, a crosslinking activator, 20-100 w.p. of carbon black mixed with 100 w.p. of a rubber component. The carbon black has CTAB surface area of 60-105 m2/g, oil absorption 24M4DBP 70-105 cm3/100 g, N2SA/IA 0.88-0.95, and satisfies the formula: TINT(%)+0.4×oil absorption 24M4DBP(cm3/100 g)-0.5×CTAB surface area (m2/g) > 106 (1).
EFFECT: invention improves tyre wear resistance, rolling resistance, manufacturability and spalling resistance.
