Abstract
Tread pattern contributes to tire/road noise through two major mechanisms: (1) tread impact due to the interaction between the tread blocks and the road and (2) air pumping due to the air compression/expansion in the tread grooves, especially at leading and trailing edges of the rotating wheel-tire. In this chapter, 22 passenger car radial tires of the same/similar size but with different tread patterns were tested on a nonporous asphalt pavement. Tread pattern noise was separated from the total tire/road noise through the techniques described in the previous chapter. For the tires tested, 3D profiles of their tread patterns have been digitized and quantified using two spectral parameters: the tread profile spectrum characterizing the tread impact mechanism and the air volume velocity spectrum characterizing the air pumping mechanism. The two spectra showed good agreement with the tread pattern noise spectrum.
