<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire having a sidewall composed of a rubber composition that can improve fuel economy, fracture strength, flex crack resistance, steering stability and processability 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, silica, and a polyalkylene glycol having a branched structure; and the rubber composition contains 5 mass% or more of a conjugate diene polymer having a specific monomer unit, in which at least one end of the copolymer is modified by a specific compound, in 100 mass% of the rubber component, and contains 5 to 150 parts by mass and 0.1 to 10 parts by mass of the silica and the polyalkylene glycol, respectively, with respect to 100 parts by mass of the rubber component.</p> |
