Abstract
Rubber tire component compositions containing silica have effective amounts of extra conductive carbon black to dissipate static electricity. The volume resistivity in Ohm-centimeters of the component such as a tread is generally 10,or less. The extra conductive carbon black generally has a BET surface area of at least 500 square meters per gram and the silica is generally utilized in amounts of at least 20 parts by weight per 100 parts by weight of the rubber.
