Abstract
The present technology provides a pneumatic tire having a strip-shaped sound-absorbing member 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 thread rubber layer. The thickness of the tread rubber layer is substantially uniform in the region X where the sound-absorbing member is located so that the difference between the thickness tat an end of the sound-absorbing member and the thickness tat the position of the tire equator is equal to or less than 0.5 mm. The thickness of the tread rubber layer is smaller in the region Y where the belt edge cover layer is located than in the region X so that the difference between the minimum value tof the thickness in the region Y and the thickness tranges from 1.0 to 4.0 mm.
