Abstract: This invention is based upon the unexpected discovery that rice husk ash silica (synthetic amorphous silica from rice husk ash) provides an exceptionally good combination of properties when used in certain tire tread rubber formulations, such as an excellent combination of traction, tread-wear, and rolling resistance. These tread rubber formulations are comprised of a blend of high cis-1,4-polybutadiene rubber and a solution styrene-butadiene rubber which is preferably functionalized with amine groups, siloxy groups, thiol groups, carboxyl groups, or groups that are reactive with hydroxyl groups present on the precipitated rice husk ash silica. The use of such rice husk silica as a reinforcing-filler in rubber formulations is also highly desirable because such silica is a sustainable resource (bio-renewable) which is derived from an agricultural waste material which would otherwise be discarded as an undesirable waste product.
