The present invention provides high-speed durability to a tire having a strip-shaped sound absorber bonded on the inner surface of a region corresponding to a tread part, reduces the distortion of the inner surface of the tire due to centrifugal force during high-speed traveling, and prevents the detachment of the sound absorber. A pneumatic tire having a strip-shaped sound absorber bonded on the inner surface of the tire includes a plurality of belt layers, two or more belt cover layers, one or more belt edge cover layers, and a tread rubber layer that are disposed outside a carcass layer in a tread part. The thickness of the tread rubber layer is substantially uniform in the area (X) where the sound absorber is located so that the difference between the thickness (t1) at an end of the sound absorber and the thickness (t0) at the equatorial position of the tire is equal to or less than 0.5 mm. The thickness of the tread rubber layer is smaller in the area (Y) where the belt edge cover layer is located than in the area (X) so that the difference between the minimum value (t2) of the thickness in the area (Y) and the thickness (t0) ranges from 1.0 to 4.0 mm. |
