FIELD: chemistry.
SUBSTANCE: invention relates to a rubber mixture (versions), a tyre and a method of reducing viscosity of unvulcanised rubber (versions). The rubber mixture is obtained by blending at least one rubber component selected from natural rubber and/or diene-based synthetic rubber, with white filler and at least one monoalkanolamine of formula 
where R1 is an alkyl group or an alkenyl group having 1-13 carbon atoms, wherein the alkyl group and the alkenyl group can be of any type: straight (normal type), branched type or cyclic type; and R2 denotes a hydroxyalkyl group or a hydroxyalkyl group having an oxyalkylene link.
EFFECT: obtaining a rubber mixture having improved silicon dioxide dispersity and which can also be improved when heating during deformation and has improved processability without increasing viscosity of unvulcanised rubber and slowing the vulcanisation rate.
