Working Party on Noise and Tyres | Session 72 | 7-9 Sep 2020
Geneva

This session is scheduled to be held in Geneva, starting on 7 September at 12.30 p.m. and concluding on 9 September at 5.30 p.m.

Agenda Item 5. (a)
UN Regulation No. 30 (Tyres for passenger cars and their trailers)

10. The expert from the European Tyre and Rim Technical Organization (ETRTO) introduced a proposal for amendments that allows for tyre marking methods other than moulding (ECE/TRANS/WP.29/GRBP/2020/12). GRBP adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2021 sessions as a draft Supplement 23 to the 02 series of amendments to UN Regulation No. 30.

11. The expert from France proposed a new definition of “radial tyre” (ECE/TRANS/WP.29/GRBP/2020/21 and GRBP-72-22), which was amended by the expert from EC (GRBP-72-24). The expert from Japan held the view that the proposal was not sufficiently clear. The expert of ETRTO pointed out that his organization would need technical justification to support the proposal. The Chair invited all experts concerned to internally re-discuss the proposal and to submit an updated document to the next session.

12. The expert from ETRTO recalled the recent adoption of Amendment No. 2 to UN GTR No. 16 (Tyres) and proposed to elaborate a roadmap for transposing of its provisions into appropriate UN Regulations (GRBP-72-07). GRBP thanked ETRTO for the initiative and agreed to revert to this issue at the next session.
