Abstract [en]

The NordTyre project was initiated to investigate the effects of EU tyre label regulation Reg (EC) No1222/2009 on labelling of tyre noise in the Nordic countries. 31 passenger car tyres were tested on 30 Nordic road surfaces in Denmark, Norway and Sweden using the CPX method. A main result is a bad correlation between the measured noise levels and the noise labels of the tyres. The tyre label measurements are made with the Coast-By method (CB), which differs from the CPX method. Further, 30 truck tyres were tested by the CB method on four different pavements. The results of testing both passenger car and truck tyres shows that the noise performance on typical Nordic rougher-textured SMA road surfaces is remarkably different compared to the smoother ISO test surface used for noise type approval. Based on these results, noise scenarios of the effect of using a combination of less noisy tyres and road surfaces have been analysed against the background of national noise mappings in Denmark and Norway. The results of the calculations show that there is a general noise reducing potential and an estimated potential to reduce the Number of Highly Annoyed people from roads by 13 % in Denmark and 19 % in Norway.
