Discussions and Outcomes
76th GRBP session (5-7 Sep 2022)

23. The expert from ETRTO introduced an amendment proposal on a “traction tyre” (ECE/TRANS/WP.29/GRBP/2022/17). GRBP adopted the proposal, as amended by GRBP-76-31, and requested the secretariat to submit it for consideration and vote at the March 2023 sessions of WP.29 and AC.1 as part of the draft new 04 series of amendments to UN Regulation No. 117.

70th GRBP session (11-13 Sep 2019)

18. The expert of ETRTO pointed out the need for a new definition of “traction tyres”, because the current definition did not well segregate real traction tyres from non-traction ones (GRBP-70-19). The experts from OICA commented on the document. The Chair invited ETRTO, in cooperation with OICA, to prepare a formal proposal for consideration at the next session.
