UN Regulation No. 117 (Tyre rolling resistance, rolling noise and wet grip)

GRBP is invited to consider a proposal for the 04 series of amendments to UN Regulation No. 117 submitted by the experts from the European Commission.

GRBP will address a proposal prepared by the experts from ISO that brings the latest ISO 10844 standard test surface into the UN Regulation.

GRBP will be briefed on the activities of the IWG on Wet Grip Performance of Tyres in Worn State (IWG WGWT) and will consider their proposals for the moulded standard reference test tyre and wet grip of C2, C3, and some clusters of C1 tyres in worn state.

GRBP will consider an amendment proposal concerning a “traction tyre” tabled by the expert from ETRTO.

GRBP is invited to address proposals submitted by the experts from ETRTO which aim to introduce provisions for type approval of special use tyres that fulfil the requirements for snow performance.

GRBP may also wish to consider corrections of editorial errors proposed by the expert from ETRTO.

At its previous session, GRBP noted that the experts from France continued consultations on monitoring the machine deviation for rolling resistance measurements (ECE/TRANS/WP.29/GRBP/73, paragraph 24 and GRBP-74-04). GRBP may wish to be informed on the outcome of this activity.
