Abstract

Recent studies show that tyre/road noise level is significantly influenced by the combinations of tyre and road surfaces. Three popular brands of tyres comprising Michelin Primacy LC, Dunlop SP Sport LM703, Dunlop Direzza DZ101 and Yokohama C.drive AC01 which have various tyre patterns (directional, bi-directional and asymmetric) and sizes (rim size ranges from R14 to R18) were tested on a dense bituminous surface and a porous asphaltic surface with a CPX vehicle according to the ISO/DS 11819-2. The tests were performed at two driving speeds of 50 and 70 km/h (the posted speed limit of the roads is 70 km/h). It was found that the Michelin Primacy LC was the quietest while the Yokohama C. drive was the noisiest in both road surfaces and driving speeds. This phenomenon was more prominent for the porous asphalt. The peak noise was found at around 1000 Hz frequency band for the dense asphalt surface but at around 500 - 630 Hz frequency bands for the porous asphalt at both driving speeds. The aged tyres may not be nosier depending on tyre interactions on the road surfaces. The rubber hardness and tread depth have opposing effects on tyre/road noise. The tyre size has no significant effect on road noise.
