89. Agenda item 16.7, Tyres. The representative of the EU proposed to include rolling resistance requirements into the gtr (ECE/TRANS/WP.29/2010/80). The representative of the United States of America could not support this proposal as it questioned a long standing agreement on the core elements of the gtr and the associated time scale, which had been reconfirmed in the November 2009 session. AC.3 recommended that the EU coordinate the proposal with China, India, the Russian Federation, the United States of America and other interested parties to try to reach a consensus. The representatives were invited to request their GRRF experts to send comments on the draft gtr for consideration at the next meeting of the informal group, scheduled for September 2010.
