Agenda Item 4. (a)
UN Regulation No. 30 (Tyres for passenger cars and their trailers)

Based on a new proposal by the expert from the European Tyre and Rim Technical Organisation (ETRTO), GRBP will continue consideration of a new definition for “radial tyre”. The ETRTO proposal also addresses 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.
