• NGOs– ETRTO, OICA, JATMA, RMA, VDA


RECAP ON PREVIOUS GTR

• Fall 1997 – tyre sector chapter settled in the TABD (Trans-Atlantic Business Dialog) -> tested-approved once – accepted everywhere

• Focus on ECE 30 and FMVSS 109 -> GTS2000• Presented to GRRF based on the ’98 Agr. -> OK

to start a WG for a GTR with UK chairmanship• Feb. 2002 -> submitted a proposal to GRRF• Oct. 2002 -> Due to TREAD Act the project was

stopped


SUGGESTIONS• Communication tool to promote GTR to countries non-CP of

UNECE • NG to refer to GTS2000 due to the various changes occurred

mainly to FMVSS• Priority on sidewall markings harmonization• Select the best regulatory practice – most appropriate

standard (engineering, physical and scientific point-of-view, related to real world performance and validated)

• For approval of a world class tyre• Economical evaluation in case of specific requirement (world

class vs regional requirements)• Table of recognition with acceptance of test methods by

Countries (no need for supplementary markings)• Define precisely the tyre type vs vehicle type (ref. SR1 vehicle

mass and categories harmonization of UNECE WP.29)


INTRODUCTION

• The Tyre Industry, in order to be a global player in the global market, currently is required to comply with a number of different national or even regional requirements that exist across the global market and which add cost, leadtime and complexity to tyres.


SCOPE

• “The objective of the GTR is to establish harmonized requirements for geometric dimensions, marking, performance, testing procedures and selection and fitting of new pneumatic tyres which are primarily designed for use on the road insert vehicle category.”


GTR WG STRUCTURE

• Chairman - TBD

• Sponsor – France (Mr. Gauvin)

• Secretary – Tyre Ind. (ETRTO, JATMA and RMA)

• CP representatives

• NGOs

• ISO (ISO 10191)


WORK BREAKDOWN STRUCTURE

• Test methods harmonization

• Sidewall markings (type approval markings, size designation, TIN, others)

• Implementation guidelines (administrative provisions, cop, quality audits, etc.)
