Supporting presentation to the ETRTO proposal for minimum wet-grip performance thresholds (document GRRF-73-18) to ensure that improvements in tire rolling resistance (per EU CO2 goals) do not result in inadequate wet-grip performance.

Supplement 2 to the 02 series of amendments to Regulation No. 117 (Document WP.29/2012/54) as adopted at the June WP.29 session contained a typo where the snow temperature range for the snow grip test should be ‐4°C to ‐15°C, but the ‘minus’ sign was omitted before the first figure.

Text prepared by the European Tyre and Rim Technical Organisation (ETRTO) in order to correct inconsistencies in time measurement accuracy in Annex 6 of UN R 117.

Proposal to revise the European Tyre and Rim Technical Organisation (ETRTO) proposals (documents GRB-58-02 and GRRF/2013/30) to correct inconsistencies in time measurement accuracy in annex 6 of the regulation.

Text as adopted by the Working Party on Brakes and Running Gear (GRRF) at its 75th session based upon a proposal by the European Commission, France and ETRTO to introduce wet grip provisions and testing procedures for tyres of categories C2 and C3.

Supplement 2 to the 02 series of amendments to Regulation No. 117 (Document WP.29/2012/54) as adopted at the June WP.29 session contained a typo where the snow temperature range for the snow grip test should be ‐4°C to ‐15°C, but the ‘minus’ sign was omitted before the first figure.
