Working Party Informal Tire Rolling Sound Emissions, Adhesion on Wet Surfaces, and Rolling Resistance Tire Noise, Wet Adhesion, and Rolling Resistance Uniform provisions concerning the approval of tyres with regard to rolling sound emissions and/or to adhesion on wet surfaces and/or to rolling resistance At the GRB meeting in January 2015 the Netherlands introduced a justification and proposal for future tyre noise limits (document GRB-61-03). During the discussion, it was suggested to investigate whether difference in performance existed between Original Equipment Manufacturer (OEM) tyres and replacement tyres, noting that the transitional provisions in EC/661/2009 take into account the earlier introduction of noise limits of OEM tyres mounted on new vehicle types. Therefore, the Dutch Ministry of Infrastructure and the Environment asked M+P to investigate the statistics of tyre noise label values in OEM tyres in more detail. 24 Aug 2015

Centrally to this, is the idea that end users need to make the correct assessment in relation to the tyre condition in order to achieve a level of safety as high as possible. Within this context, the tyre condition is considered in relation to technical elements (tyre inflation pressure, tyre tread depth, tyre damage, tyre age, and meteorological influences) and one information element (driver awareness). The study addresses the topics of tyre usage and the impact on road safety (which are the potential safety improvements related to tyre usage from a technical perspective) and how can road users be supported to use tyres that have a better safety performance by policy options. 19 Feb 2015

Proposal for Supplement 6 to the 02 series of amendments to Regulation No. 117
Working Party Working Tire Rolling Sound Emissions, Adhesion on Wet Surfaces, and Rolling Resistance Tire Noise, Wet Adhesion, and Rolling Resistance Uniform provisions concerning the approval of tyres with regard to rolling sound emissions and/or to adhesion on wet surfaces and/or to rolling resistance Proposal to introduce a “Deceleration Calculator” (dω/dt) for use in the UN R117 test procedures. This procedure was developed by Russia and validated by an ad hoc group (including NAMI, UTAC, and ETRTO). 19 Jun 2014

Proposal for Supplement 6 to the 02 series of amendments to UN Regulation No. 117
Working Party Informal Tire Rolling Sound Emissions, Adhesion on Wet Surfaces, and Rolling Resistance Tire Noise, Wet Adhesion, and Rolling Resistance Uniform provisions concerning the approval of tyres with regard to rolling sound emissions and/or to adhesion on wet surfaces and/or to rolling resistance Proposal to elaborate on the concept of tyre deceleration (dω/dt) in the test procedures. The Russian Federation has developed a “Deceleration Calculator” for use in the UN R117 procedures. Following work by an ad hoc group (including NAMI, UTAC, and ETRTO) formed to review and validate this tool, Russia has prepared this new proposal, modifying the version (document GRB/2013/10) submitted at the last GRB session. The changes primarily concern the explanation of the tool rather than the basic mathematical equations. 12 Feb 2014
