A rubber compound for the production of tire portions comprising a polymer base with a cross-linkable unsaturated chain, a filler system and a vulcanization system. The filler system comprises (a) a quantity, greater than or equal to 25 phr, of a first carbon black having a surface area smaller than or equal to 170 m2/gr; (b) a second carbon black having a surface area greater than or equal to 300 m2/gr in a quantity that is such that the ratio between the quantity of said first carbon black and the quantity of said second carbon black is greater than or equal to 5 and smaller than or equal to 13; (c) a quantity ranging between 0.5 and 2.0 phr of a dispersant agent comprised in the class of aromatic amides and having an unsaturation suited to interact with the polymer base with a cross-linkable unsaturated chain.
