A belt cushion disposed between an tire-axis-direction end of a belt layer and a carcass comprises an outer layer, an interlayer, and an inner layer which are arranged in this order inwardly in the tire-radial-direction from the tire-axis-direction end of the belt layer. The inner layer and outer layer are made of a rubber composition B having complex modulus E*b and loss tangent tan ´b. The interlayer is made of a rubber composition C having complex modulus E*c being substantially the same as the complex modulus E*b and having loss tangent tan ´c being smaller than the loss tangent tan ´b. |
