PROBLEM TO BE SOLVED: To provide a pneumatic tire which can make compatible steering stability and rolling resistance at a high dimension.SOLUTION: A pneumatic tire has a caracas 6 and sidewall rubber 3G. The sidewall rubber 3G includes an inner layer 10 and an outer layer 11. The outer layer 11 is larger than the inner layer 10 in a complex modulus of elasticity E*, and the inner layer 10 is smaller than the outer layer 11 in a loss tangent tanδ. The thickness of the inner layer 10 is gradually reduced toward the inside of a tire radial direction from the maximum width position Pm of a sidewall 3, and gradually increased toward the outside of the tire radial direction from the maximum width position Pm. The thickness of the outer layer 11 is gradually increased toward the inside of the tire radial direction from the maximum width position Pm. |
