On a pneumatic tire, a sound absorbing member is installed on an inner surface of a tread portion via a surface fastener including a pair including a hook member and a loop member, the hook member including hook-shaped elements on one surface and being fixed to the tire inner surface, and the loop member being provided with loop-shaped elements engageable with the hook-shaped elements and being fixed to the sound absorbing member. In a meridian cross-section, the loop member has at least one section partially fixed in a tire width direction to the sound absorbing member. Given a fixed region in which the loop member is fixed to the sound absorbing member, and a non-fixed region in which the loop member is not fixed to the sound absorbing member, an engaging region in which the loop member and the hook member engage each other is on the non-fixed region.

Pneumatic tire

In a pneumatic tire, a sound absorptive member is installed on an inner surface of a tread portion with a sheet material interposed therebetween. The sheet material is fixed relative to the tire inner surface or the sound absorptive member at first fixed regions. The sheet material is not fixed relative to the tire inner surface or the sound absorptive member at a non-fixed region between the first fixed regions. The sheet material is fixed at a second fixed region relative to the other of the tire inner surface or the sound absorptive member ina portion of the non-fixed region. A repair liquid introducing portion connects a closed space and a tire cavity with the sheet material, the closed space being separated from the tire cavity by the tire inner surface and the non-fixed region or the sound absorptive member and the non-fixed region in a meridian cross-section.
