Abstract This paper will focus on determining characteristics of tyre cavity resonance noise and its mitigation method. There are many factors that affect the noise transmitted to vehicle cabin, this includes coupling mode of structure and tyre air cavity which will be investigated in this paper. The results from experimental modal analysis will be compared with those from finite element modal analysis. These investigations would lead to understanding and reduction of tyre cavity resonance noise. Tyre samples were tested for their material properties using tensile tests and wheel assembly was tested for its dynamic properties through roving impact hammer tests. The frequency response data of roving impact hammer tests on a wheel tyre assembly was processed using MEScope software for identifying its mode shape. The results have shown the significant vibration response amplitude peak between 200-250 Hz is related to the tyre cavity resonance noise.
