GRBP looked forward to the outcome of the ETRTO activities and expected that a final proposal would be submitted to the next session. The experts from the Netherlands and Russian Federation pointed out that the radial tyre definition may not necessarily cover new types of tyre structures and that adding a new subgroup of tyres with their own definition should be considered as an alternative.

18. GRBP adopted ECE/TRANS/WP.29/GRBP/2022/6 and ECE/TRANS/WP.29/GRBP/2021/13, as amended by GRBP-75-31-Rev.2, and requested the secretariat to submit it for consideration and vote at the June 2022 sessions of WP.29 and AC.1 as draft Supplement 25 to the original series of amendments to UN Regulation No. 54.

GRBP-75-31/Rev.2 | UN R54: Proposal for Supplement 25 to the 00 series of amendments Proposal to avoid placing requirements in the Definitions section and to facilitate the text by making use of the definition of "service description" that was introduced by Supplement 24.

19. GRBP considered a proposal that had been prepared by the expert from ETRTO with the aim to align the definitions of “diagonal”, “bias-ply” and “bias belted” tyre structures with the definitions in UN Regulations Nos. 30 and 75 (ECE/TRANS/WP.29/GRBP/2022/7). GRBP adopted the proposal and requested the secretariat to submit it for consideration and vote at the June 2022 sessions of WP.29 and AC.1 as draft Supplement 20 to UN Regulation No. 106.

GRBP/2022/7 | UN R106: Proposal for amendments Proposal to align the definitions of “diagonal” or “bias-ply” and “bias belted” tyre structures to the definitions given in UNvR30 and R75, to improve the text with regard to description of the composition of the size designation for metric tyres, and to resolve an apparent contradiction regarding the prefixes IF and VF.

20. The experts from the Informal Working Group for Wet Grip on Worn Tyres (WGWT) reported on their progress (GRBP-75-27) and presented updated Terms of Reference of IWG WGWT (GRBP-75-28). GRBP adopted the revised Terms of Reference, as contained in Annex III to the session report.

To complement the document, the expert from IWG WGWT tabled further amendments (GRBP-75-25-Rev.1). GRBP adopted this proposal and requested the secretariat to submit it for consideration and vote at the June 2022 sessions of WP.29 and AC.1 as part of a new 03 series of amendments to UN Regulation No. 117. The expert from IWG WGWT also presented a concept proposal for addressing wet grip requirements for C2 and C3 tyres in worn state (GRBP-75-26-Rev.1).

22. GRBP agreed to request WP.29 and AC.1 to postpone to their June 2022 sessions consideration of ECE/TRANS/WP.29/2021/12, in order to combine it into a consolidated proposal with the adopted amendments mentioned in the previous paragraph.
