In ECE/TRANS/WP.29/2018/53, page 2: for “Supplement 15” read “Supplement 16”,

Insert the missing amendment to former paragraph 3.2.10, to read:

"3.2.11.An indication, by means of the “PSI” index (as explained in Annex 7, Appendix 2 to this Regulation) or in kilopascals (kPa), of the inflation pressure to be adopted for the load/speed endurance tests. This indication may be placed on one sidewall only."

Annex 7, paragraph 1.3., amend to read:
“1.3.Inflate the tyre to the pressure corresponding to the indication on the sidewall as specified in paragraph 3.2.11. of this Regulation.”
