Methods for producing a cross-linkable rubber composition that comprises a masterbatch are disclosed. The masterbatch comprising a base masterbatch and the method includes forming the base masterbatch by adding a diene rubber to an internal mixer; adding a total quantity of a solid agglomerated material that includes carbon nanotubes into the mixing chamber; and mixing the diene elastomer and the solid agglomerated material. To ensure adequate distribution and dispersion of the material, the base masterbatch has a minimum Mooney viscosity ML(1+4)100 of at least 85 MU.
