Abstract: A pneumatic tire 1 comprises a carcass 6 extending between bead cores of bead portions via a tread portion 2 and sidewall portions, and a belt layer 7 arranged on an outer side in a tire radial direction of the carcass 6 and inside of the tread portion 2. The pneumatic tire 1 further comprises a damping rubber body 30 arranged between the carcass 6 and the belt layer 7, and a noise damper 20 arranged on an inner cavity surface of the tread portion 2. A width W1 in a tire axial direction of the damping rubber body 30 is in a range of from 60% to 130% of a width W2 in the tire axial direction of the belt layer 7, and a water absorption rate of the noise damper 20 is in a range of from 10% to 25%.

Abstract: A pneumatic tire 1 comprises a carcass 6 extending between a pair of bead portions 4, 4, an inner liner 10 arranged on an inner side in a tire radial direction of the carcass 6 and forming a tire inner cavity surface 16, and a noise damper 20 made of a porous material and fixed to the tire inner cavity surface 16 of the inner liner 10. A glass transition temperature Tg1 of the noise damper 20 is lower than a glass transition temperature Tg2 of the inner liner 10.
