21. The expert of France proposed a wet adhesion requirement for C1 tyres in a worn state (ECE/TRANS/WP.29/GRB/2019/6 and GRB-69-08). The proposal received comments from ETRTO (GRB-69-10). GRB also noted a recent study on used tyres (GRB-69-09). GRB was of the view that this topic should be pursued in the framework of a new IWG and adopted its Terms of Reference (GRB-69-23), as reproduced in Annex V to the session report. Various experts expressed their willingness to contribute to the activities of the newly established IWG. The experts from France and the European Commission volunteered to act as Chair and Co-Chair, respectively, while ETRTO agreed to provide secretariat support.
