This report summarizes the results of the NordTyre projects. The report has a special focus on the effects to society of regulating tyre/road noise by using the quietest tyres available on the market together with road surfaces with reduced noise emission. The report includes the main results on noise from passenger car tyres and truck tyres, conclusions and recommendations of the NordTyre projects. Labelling of new tyres became mandatory in all EU and EEC countries in 2012. Nordic road administrations work on reducing traffic noise exposure by applying noise reducing road surfaces, by building and maintaining noise barriers etc. There is a need to know how “less noisy” tyres and road surfaces could contribute to traffic noise mitigation.
