The experts from France, the Netherlands and BIPAVER proposed to align the provisions for retreaded tyres with the previously adopted proposals for UN Regulations Nos. 54 and 117 and to cover all tread materials (ECE/TRANS/WP.29/GRBP/2021/16). The expert from ETRTO commented on the proposal and suggested further modifications (GRBP-74-29-Rev.1 and GRBP-74-30-Rev.2). GRBP adopted the proposal with the amendments in Annex IV and requested the secretariat to submit it for consideration and vote at the March 2022 sessions of WP.29 and AC.1 as draft Supplement 11 to UN Regulation No. 109.
