Rubber compositions having a base masterbatch, the base masterbatch comprising a diene rubber and a solid agglomerated material comprising disaggregated carbon nanotubes consisting of a continuous network of carbon nanotubes, the continuous network comprising 1) voids and 2) aggregates of carbon nanotubes having a d50 mean size of less than 5 μm, the voids and the aggregates together being in an amount that is less than 60% of a predetermined surface area, such percentage as determined by electron microscopy image analysis, the remainder being the disaggregated carbon nanotubes in the continuous network that do not comprise a clearly defined shape and being in an amount that is at least 40% of the predetermined surface area, wherein the base masterbatch has a minimum Mooney viscosity ML(1+4)100 of at least 85 MU; and a cure system.
