The particulate kaolin particles may comprise calcined kaolin chosen from at least one of particulate soak calcined kaolin and particulate flash calcined kaolin. The rubber composition can comprise additional particulate fillers including those chosen from silica, carbon black, and other particulate fillers. Also disclosed herein is a process for producing such a composition, and the method of using a cured form of the composition in a rubber composition, such as a vehicle tire composition.
