<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire in which low rolling resistance, elastic modulus and wear resistance are made highly compatible. <P>SOLUTION: The pneumatic tire uses a rubber composition in its tire member, which contains a hydrazone compound and carbon black having a nitrogen adsorption specific surface area (N<SB POS="POST">2</SB>SA) of >130 and ≤160 m<SP POS="POST">2</SP>/g and a dibutyl phthalate (DBP) oil absorption amount of 60-170 mL/100g to 100 pts.mass of a rubber component containing modified natural rubber obtained by adding a polar group-containing monomer to a natural rubber latex, then subjecting the monomer to graft polymerization with the natural rubber in the natural rubber latex, and coagulating and drying the resulting rubber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
