The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2016/12, a revised proposal to amend the tyre marking requirements and also containing the amendments previously proposed by the expert from Slovakia. GRRF adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as part of the draft Supplement 21 to Regulation No. 54 and as part of the draft Regulation No. 117.

38. The expert from ETRTO also introduced ECE/TRANS/WP.29/GRRF/2015/27 as amended by GRRF-80-10 proposing to replace the “PSI index” by the pressure in “kPa”. The proposal received several comments e.g. on paragraph 3.1.10. and the use of “may” or “shall”. GRRF agreed to resume consideration of this proposal at its next session on the basis of a revised proposal that the expert from ETRTO volunteered to prepare.
