13. Based on a study (GRBP-76-04), the expert from ETRTO proposed a new definition for “radial tyre” (ECE/TRANS/WP.29/GRBP/2022/21). The proposal also addressed other issues, such as the definition of snow tyres, requirements for special use tyres of class C1, addition of an optional prefix for extra load tyres, a clarification on the description of the load/speed test for run flat/extended mobility tyres and editorial corrections.

14. GRBP adopted ECE/TRANS/WP.29/GRBP/2022/21 and requested the secretariat to submit it for consideration and vote at the March 2023 sessions of WP.29 and AC.1 as draft Supplement 25 to the 02 series of amendments to UN Regulation No. 30.
