Based on the outcome of an informal meeting convened by the Chair on 21 May 2019, GRBP may wish to resume its discussion on issues that should be included in the future work.

GRBP is also expected to be informed by the expert from the International Organization of Motor Vehicle Manufacturers (OICA) about the outcome of their study that aims to find out if lowering the rolling sound limits would affect other tyre parameters which are essential for vehicle safety and CO2 reduction (GRB-69-25-Rev.1).
