30. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2018/5 with editorial correction and a number of imperial tyre sizes updated in Annex 5. He also introduced ECE/TRANS/WP.29/GRRF/2018/11 as a consolidated version of UN Regulation No. 54, containing ECE/TRANS/WP.29/GRRF/2018/5. GRRF adopted ECE/TRANS/WP.29/GRRF/2018/11 as amended (GRRF-86-23 and GRRF-86-26) and as reproduced in Addendum 1 (based on GRRF-86-43) to the report. GRRF requested the secretariat to submit this amended proposal as draft Supplement 23 to UN Regulation No. 54 to WP.29 and AC.1 for consideration and vote at their June 2018 sessions.
