Russia prepared this revision to the draft Statement of Rationale (following the 16 September 2011 meeting) to clarify its proposal for a global tire marking, addressing concerns expressed by NHTSA on the use of plant codes.

The Russian Federation proposes to introduce a “global tire marking” within the framework of the 1958 Agreement pursuant to the provisions of the Tire GTR. Russia intends this to encourage harmonization in the national applications of the GTR while enabling mutual recognition of approvals.

Discussion paper outlining concerns over particulates originating from tire erosion and suggesting a need for global regulatory provisions to limit such environmental risks.

Proposal to prepare an amendment to UN Global Technical Regulation (GTR) No. 16 on tyres in order to introduce provisions concerning wet grip performance, rolling resistance, and qualification of tyres for use under severe snow conditions in accordance with the same provisions introduced recently into UN Regulation No. 117.

Status of the draft text to introduce provisions for tyre rolling resistance and snow performance testing into the global technical regulation on tyres.

Proposal is to align GTR 16 with technical progress, incorporating new provisions for wet grip performance, rolling resistance and qualification for use at severe snow conditions both for passenger car (PC) and light truck / commercial (LT/C) tyres (as were recently adopted within UN Regulation No. 117). The proposal also includes updates from relevant FMVSS and UN Regulations Nos. 30 and 54.

Explanatory report on the development and contents of the amendment concerning wet grip, rolling resistance, and other updated provisions for GTR 16 on tyres.

Draft text showing changes made to the GTR on tyres under Amendment 1 (which is primarily aimed at introducing provisions for tyre rolling resistance and performance in severe snow conditions).

Proposal to develop amendments to Part II of GTR No.16:

1. Addition of new definitions (Section 2);
2. Harmonization of the Load Range concept in relationship to Inflation Pressure (Section 2),
3. Alignment of the provisions for tyre marking and physical dimensions of PC tyres with the most recent developments in UN Regulations Nos. 30 and 54 (Sections 3.3 and 3.5),
4. Harmonization of FMVSS 139 requirements relative to UNECE PSI index (Sections 3.14 and 3.15),
5. Deletion of provisions for physical dimensions of LT/C tyres based on FMVSS 139 (Section 3.20) an UN Regulation No. 54 (Section 3.21) and addition of new harmonized provisions for physical dimensions of LT/C tyres (new Section 3.20),
6. Deletion of provisions for high speed test for LT/C tyres based on FMVSS 139 (Section 3.19) and UN Regulation No. 54 (Section 3.16) and addition of new harmonized provisions for high speed test for LT/C tyres (new Section 3.16),
7. Updates of the Annexes 3 and 6 with regard to the most recent developments in UN Regulations Nos. 30 and 54.

Other topics to be discussed within the informal working group for the Phase 2 of development of UN GTR No. 16 include:

1. Consideration of feasibility of harmonization of endurance test for LT/C tyres (Sections 3.16 and 3.17), and
2. Consideration of feasibility of development of provisions for global tyre marking.

Presentation from Russia discussing possibility for a system of global tyre markings to signify compliance with GTR No. 16 (Revision 4 in a series of draft proposals on global tyre markings).

Status after the 19th IWG Meeting (Geneva, 11-12 September 2018)

Amendment 2 to UN GTR No. 16 addresses the harmonization of the previously non-harmonized tests applicable to for light truck / commercial (LT/C) tyres, specifically Physical Dimensions Test and High-speed Test. Amendment 2 also covers the most recent updates of UN Regulations Nos. 30 and 54 as well as the FMVSS of the United States.
