ABSTRACT:
Disclosed is a rubber composition having excellent low loss characteristics and capable of imparting a tire with wear resistance and fracture resistance. The rubber composition is obtained by blending a carbon black, which has a toluene coloring transmittance of not less than 90% while satisfying the following relation between the hydrogen emission rate (mass %) and the cetyltrimethylammonium bromide adsorption specific surface area (CTAB) (m2/g): the hydrogen emission rate >0.260−6.25×10−4×CTAB, into a modified natural rubber which is obtained by adding a polar group-containing monomer into a natural rubber latex for graft-polymerizing the polar group-containing monomer to a natural rubber molecule in the natural rubber latex, and then solidifying and drying the resulting product.
