FIELD: chemistry.

SUBSTANCE: invention relates to a rubber mixture, and to a tyre, and to the rubber mixture, suitable for the application as a component of the tyre framework, especially as rubber for the tyre bead filler and to the tyre, in which the said rubber mixture is applied. The rubber mixture contain a caoutchouc component, selected from, at least, one of natural caoutchouc and synthetic caoutchouc, and a resin composition, containing resorcinol resin of a novolac type and phenol resin of a resol type, in an amount from 1 to 30 wt.p. calculated per 100 wt.p. of the caoutchouc component. The content of dimethylene ether groups in phenolic resin of the resol type constitutes from 20 mol. % to 100 mol. % relative to the total content of binding groups, obtained from aldehydes, binding aromatic rings, obtained from phenol, to each other. The absence of application of hexamethylenetetraine or hexamethoxymethylmelamine as a hardening agent results in an increase of the hardening ability and thermal stability of the resin composition, with the rubber mixture possessing characteristics of high elasticity, large rupture elongation and low heat release.

EFFECT: tyre, containing the said rubber mixture in the bead part of the tyre, possesses an increased service term when applied.
