To provide a pneumatic tire capable of enhancing the durability by radiating heat in a hollow inside tire demarcated by a tire and a rim outside via the rim.

The pneumatic tire 1 comprises a tread part 2, a pair of side wall parts 3 extending inwardly in the tire radial direction from its both sides, and a bead part 4 which is continuous to the inner side of each side wall part 3 and seated on the rim J. A heat conductive rubber 10 having the heat conductivity of ≥0.10 W/(m K) is provided on the hollow inside tire surface side of the bead part 4, and at least a part of the heat conductive rubber 10 is brought into contact with the rim J in a normal state.
