A rubber composition is disclosed comprising: at least 20 phr of a composite material comprising a reinforcing carbon black dispersed in natural rubber; at least 3 phr or at least 5 phr of a conjugated diene elastomer, the composite material and the conjugated diene elastomer together providing at least 90 phr or a total of 100 phr of vulcanizable elastomers in the rubber composition; a cure activator; and a sulfur-based cure agent. Also, a method of forming a rubber composition is disclosed, the method comprising the steps of: providing at least 20 phr of a composite material comprising a reinforcing carbon black dispersed in natural rubber and at least 3 phr or at least 5 phr of a conjugated diene elastomer, and blending said composite material and said conjugated diene elastomer at a temperature of at least 115°C to form a mixture, the mixture optionally further comprising silica; and thereafter, blending the mixture with a sulfur-based cure agent; the composite material and the conjugated diene elastomer together providing at least 90 phr or a total of 100 phr of vulcanizable elastomers in the mixture.
