PROBLEM TO BE SOLVED: To provide a pneumatic tire having at least one member selected from the group consisting of a sidewall, a ply topping and a breaker topping that is improved in various performances such as fuel economy, processability, thermal aging resistance, flexure crack growth resistance, adhesion strength, and breaking strength in a well balanced manner.SOLUTION: The pneumatic tire has at least one member selected from the group consisting of a sidewall, a ply topping, and a breaker topping that is manufactured by using the following rubber composition. The rubber composition comprises a modified natural rubber that is highly purified and adjusted to a pH of 2 to 7, silica (A) having a nitrogen adsorption specific surface area of 110 m/g or less, and a silica (B) having a nitrogen adsorption specific surface area of 180 m/g or more, in which contents of the silica (A) and the silica (B) satisfy an expression of (content of silica (A))×0.2≤(content of silica (B))≤(content of silica (A))×6.5. |
