Zusammenfassung:	The disclosed technology generally relates to apparatuses for reducing or cancelling noise generated by a tire in motion, and more particularly to a noise-reducing apparatus including a sound-absorbing foam and a fixing structure for attaching and fixing the sound-absorbing foam to a tire. In one aspect, the noise-reducing apparatus for a tire includes a sound-absorbing foam configured to reduce noise generated by the tire by absorbing sound generated by the tire in motion when attached to an inner liner of a tire. The noise-reducing apparatus additionally includes a plurality of fixing bands configured to fix the sound-absorbing foam to an inner side of the tire. Each of the fixing bands has an attaching portion configured to be fixed to the inner side of the tire and has a pressing portion configured to bring and keep the sound-absorbing foam in contact with the inner liner. The pressing portion is configured to apply an elastic force on the sound-absorbing foam by extending and contracting. The disclosed technology also relates to a tire having the noise-reducing apparatus and a method of integrating the noise-reducing apparatus to a tire.
