摘要： A pneumatic tyre 1 includes 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 tyre radial direction of the carcass 6 and inside of the tread portion 2. The pneumatic tyre 1 has 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 tyre axial direction of the damping rubber body 30 is in a range of from 60% to 130% of a width W2 in the tyre axial direction of the belt layer 7, and air permeability of the noise damper 20 measured in accordance with the Japanese Industrial Standard JIS-L1096 is 3.0 cm3/cm2/s or less.

摘要： A pneumatic tire includes a ply having a plurality of cords each having an average cord diameter D, and a sidewall rubber having a loss tangent tan δ The plurality of cords each includes a plurality of filaments twisted together, the plurality of filaments each having an outer diameter d. The plurality of cords each has a ratio D/d of the average cord diameter D to the outer diameter d being equal to or more than 28. The ratio D/d and the loss tangent tan δ of the sidewall rubber satisfy the following formula; (tan δ)/(D/d)*1000≤5.5.
