PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving uneven wear resistance by suppressing shoulder wear, and securing durability by a belt cushion layer.SOLUTION: The pneumatic tire includes a carcass layer 4 provided between a pair of toes of bead, a belt layer 5 arranged on the outer peripheral side of the carcass layer 4 in a tread part 3, and a belt cushion layer 7 interposed between the end of the belt layer 5 and the carcass layer 4. The belt cushion layer 7 includes a high modulus rubber 7a forming the main body of the belt cushion layer 7 and having a modulus at 100% elongation of 4.0-8.0 MPa, and a low modulus rubber 7b interposed between the carcass layer 4 and the high modulus rubber 7a and having a lower modulus at 100% elongation than that of the high modulus rubber 7a. |
