A tyre tread compound, showing good performance and high electrical conductivity, was prepared with a high silica loading and a low loading of multi-wall carbon nanotube in order not to sacrifice the original mechanical properties of the rubber compound. We fabricated styrene-butadiene rubber/natural rubber composites containing carbon black as a general filler and two types of multi-wall carbon nanotube with different structure and dimension, entangled carbon nanotube with short length (<10 mu m) and parallel-aligned carbon nanotube bundles with a long length (<120 mu m) as a specific filler. The incorporation of the aligned multi-wall carbon nanotube into the high silica rubber compound, even at low loading (0.5 phr), improved the static dissipation to a level that could meet the requirements (<10(8) Omega) for tyres without a measurable decrease in the physical and dynamic properties. The abrasion resistance was also enhanced considerably by 15 % or more.
