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 t1 at an end of the sound-absorbing member and the thickness t0 at 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 t2 of the thickness in the region Y and the thickness t0 ranges from 1.0 to 4.0 mm.
Abstract:
The present technology provides a pneumatic tire having a mechanical fastener member for attaching an object with specific functionality to an inner surface of the pneumatic tire, particularly, a pneumatic tire such that, as the pneumatic tire rolls, the object with the specific function attached by the mechanical fastener member can be effectively prevented from executing rotating motion about the mechanical fastener member as a rotation central axis. The pneumatic tire of the present technology has a first member of a mechanical fastener separable into two members, disposed on the tire inner surface. On the tire inner surface around the mechanical fastener member, a recessed flat surface region is formed as a recessed portion having a step from peripheral portions of the recessed portion.
Abstract:
