25. The Chair of GRRF recalled the purpose of ECE/TRANS/WP.29/2013/63 (Draft UN GTR on tyres), amended by ECE/TRANS/WP.29/GRRF/2014/20 (adopted at the seventy-seventh session of GRRF), and ECE/TRANS/WP.29/2013/122 (the corresponding technical report).

26. The expert from France presented GRRF-78-18 introducing minor updates to ECE/TRANS/WP.29/2013/63 and ECE/TRANS/WP.29/2013/122. He added that the timeline for further development of the gtr had to be updated, taking into account the delay to adopt phase I. GRRF adopted GRRF-78-18 as amended by GRRF-78-47 and as reproduced in Annex III to this report. GRRF requested the secretariat to submit the proposal to WP.29 and AC.3 for consideration at their November 2014 sessions.

27. GRRF reviewed the ECE/TRANS/WP.29/GRRF/2014/20 containing the amendments defined at the seventy-seventh GRRF session. The Chair recalled that GRRF previously agreed that updates to the UN GTR on tyres would be proposed after its establishment in the global registry by AC.3 to keep it in line with the latest regulatory developments.

28. Finally, the expert from France advised GRRF that his country would not be able to sponsor phase 2 of the UN GTR on tyres once phase 1 was concluded.
