<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire using a rubber composition that can improve fuel economy, fracture strength, flexure crack resistance, and steering stability in a well balanced manner.SOLUTION: The pneumatic tire includes a sidewall composed of the following rubber composition. The rubber composition comprises a rubber component and silica. In the composition, a content of a specific conjugated diene polymer is 5 mass% or more in 100 mass% of the rubber component; the silica has such properties that when a particle to which three or more particles are adjoining is denoted as a branched particle Z, an average length Wbetween branched particles (Z to Z) including the branched particles Z is 30 to 400 nm; and a content of the silica is 5 to 150 parts by mass with respect to 100 parts by mass of the rubber component.</p> |
