(57) [Summary]n100 parts by weight of a vulcanizable elastomer suitable for use in a tire, from about 1 to about 100 parts by weight of a reinforcing silica filler per 100 parts by weight of the elastomer, and a polystyrene having alkali metal ions dissolved therein. Tire tread compositions containing from about 0.1 to about 15 parts by weight of the electrically conductive additive, including the (alkylene oxide) containing polymer, per 100 parts by weight of the elastomer provide improved electrical conductivity. Pneumatic tires having improved static charge annihilation properties using the tread compositions described above, and related methods of using the tread compositions to eliminate static charge from tires are described. |
