Abstract
A method of producing a rubber compound, which includes mixing at least one cross-linkable unsaturated-chain polymer base, silica with a surface area of 100-220 m/g, a first silane coupling agent in the polysulphide organosilane class, and a second silane coupling agent in the class of mercaptosilane protected in the form of thioester, and whereby the second silane coupling agent is added to the mix after the first silane coupling agent has reacted with the silica.
