  1. NordTyreTyre labelling and Nordic traffic noise Background • Traffic noise is a topic important to all Nordic countries, as we all are concerned with the steadily increasing traffic noise • Labelling of new vehicle tyres will be mandatory in all EU and EEC countries from November 2012. The label contains values of three parameters: wet grip, rolling resistance and noise. • There is a need to know how “low noise” tyres can contribute to noise abatement and to clarify how this contribution can be optimized

  2. NordTyreTyre labelling and Nordic traffic noise Goals • Clarify which combinations of tyres and pavements will yield the lowest noise emission, influencing the environment along roads and highways.  This knowledge will be the basis for qualified decision making concerning actions to mitigate traffic noise in the Nordic countries. • Clarify the noise emission from tyres, including Nordic winter tyres and its possible correlation with wet grip, snow grip and ice grip.  These results can be used to define realistic new tyre noise level limits that could be used in a future revision of the EU tyre labelling, Reg (EC) No1222/2009, and the tyre noise limits in Reg (EC) No 661/2009, including snow grip and ice grip in addition to wet grip.

  3. NordTyreTyre labelling and Nordic traffic noise Status • State-of-the-Art report finalised March 2012 • Recommendations for • Tyres to test • Road surfaces • Methodology for measurements • Procurement for tyres has started • Measurements start summer2012 • Field measurements of noise • Laboratory measurements of rolling resistance

  4. NordTyreTyre labelling and Nordic traffic noise Organisation • Project steering group (PSG) • Nordic Road authorities • Nordic Transport authorities • Project coordinating group (PCG) – Project leader • Advisory group (AG) • Observer

  6. NordTyreTyre labelling and Nordic traffic noise Common obligation model (ERA-Net Road) • Common project • Common goals • Common pot of money

  7. NordTyre - 4 defined parts We have defined the following parts of the project: • Part 1: State-of-the-art + new tyres on representative pavements • Part 2: Relation between noise, wet grip, snow grip and ice grip • Important since wet grip and snow grip seems to be contradictory qualities • Regulatory Committee on tyres welcomes input on this issue • Part 3: Truck tyres • How much do they contribute to traffic noise? • Lenient limits in the EC regulation • Part 4: Combined effects of tyre aging and pavement ageing
