15. The experts from France and EC introduced an updated proposal for the new definition of “radial tyre” (ECE/TRANS/WP.29/GRBP/2021/9). The same definition was also proposed for UN Regulations Nos. 54, 75, 106, 108 and 109 ECE/TRANS/WP.29/GRBP/2021/10. The experts from Canada and the United States of America raised a number of questions on the proposal (GRBP-74-07) and pointed out that they had started consultations with the authors. GRBP invited the stakeholders, in liaison with ETRTO, to continue discussions and agreed to come back to the proposal at the next session. |
