<P>PROBLEM TO BE SOLVED: To provide a rubber composition that is especially excellent in interaction between a rubber component and carbon black and/or silica, improves dispersibility of these fillers more, and is excellent in low heat generation and abrasion resistance; and to provide a pneumatic tire obtained by using the composition and having the characteristics described above. <P>SOLUTION: The rubber composition is obtained by blending 10-150 pts.mass of a reinforcing filler (C) and less than 1 pts.mass of an organic acid (D) based on 100 pts.mass of a rubber component comprising 5-90 pts.mass of a modified polymer (A) including a heterofunctional group capable of generating an onium cation by an acid and 95-10 pts.mass of another polymer component (B). <P>COPYRIGHT: (C)2012,JPO&INPIT |
