32. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2018/6 and ECE/TRANS/WP.29/GRRF/2018/7 (amended by GRRF-86-31) with tyre sizes and tyre classification codes common in the United States of America and standardised by the Tire and Rim Association Inc. and with marking provisions on inflation pressure (for measurements and tests). He also introduced ECE/TRANS/WP.29/GRRF/2018/12 as a consolidated version of UN Regulation No. 106, containing ECE/TRANS/WP.29/GRRF/2018/6 and ECE/TRANS/WP.29/GRRF/2018/7. GRRF adopted ECE/TRANS/WP.29/GRRF/2018/12 as amended and reproduced in Addendum 2 (based on GRRF-86-42) to the report. GRRF requested the secretariat to submit this amended proposal as draft Supplement 16 to UN Regulation No. 106 to WP.29 and AC.1 for consideration and vote at their June 2018 sessions.
