Document proposing regulations for inclusion in the pending regulation on International Whole Vehicle Type Approvals and providing guidance to the Working Parties in their respective reviews of this work.

Proposal to correct the omission of the rim-diameter code 25 for the calculation of metric-designated tyres (this rim code appears in Annex 5, Table 7 for code designated tyres).

Proposal to allow the use of test tracks constructed according to the new ISO 10844:2011.

Proposal to align the definition of the temperature correction coefficient “K” in UN Regulation No. 117: 02 series of amendments with ISO 28580. The issue is linked to tire categories: ISO refers only to load index while UN R117: 02 series refers to class C1, C2 and C3 tires.

European Tyre and Rim Technical Organisation (ETRTO) proposal to amend the snow test method for C3 tyres in order to prescribe the wider of the possible speed ranges.

Four paragraphs in the draft gtr (version 24 Feb) contained references to type approval when the text should be neutral concerning type approval or self-certification. The text in these paragraphs was therefore changed.

Second revision to the overview of open items in the development of the International Whole Vehicle Type Approval regulation organized by article and annex of the draft regulation.

Third revision of the project plan for development of the proposed regulation to establish an International Whole Vehicle Type Approval.

Proposal from the Netherlands to update requirements on the noise test track to the from ISO 10844:1994 to ISO 10844:2011, including provisions for the repaving of non-compliant tracks. The proposal offers two approaches: reference to IS0 10844:2011 or reproduction of the ISO text.

The 1958 Agreement subgroup was established to assist the IWVTA Informal Group in preparing a draft text for the revision of the 1958 Agreement pursuant to the development of the International Whole Vehicle Type Approval system.

Proposed text and supporting report for the establishment of a global technical regulation on light vehicle tires, submitted to the Working Party on Brakes and Running Gear for approval by the Informal Group on the Tyre GTR.

Proposal to improve accuracy in the calculation of tire rolling resistance by the deceleration method.

Submission by the GRB secretariat to correct an editorial error where the noise test track specifications should refer to the requirements of ISO 10844:2011 rather than “Annex 4” as stipulated in the original draft.

Preliminary report prepared by France on the development of a global technical
regulation concerning uniform provisions for pneumatic radial tyres for passenger and light truck (commercial) vehicles.

German position paper arguing for greater objectivity and clarity over the use of the proposed “M+S”, “M.S”, “M&S”, and “Alpine” symbol with regard to “snow tyres” and “snow tyres for use in severe snow conditions”.

Presentation considering tyre rolling sound emissions where pavement, tyre and vehicle all play major roles and where traffic flow management and driver behavior are taken into consideration.

Table prepared by OICA highlighting various elements in the consideration of noise in UN Regulation Nos. 9, 28, 41, 51, 59, 63, 92, and 117.

GRB revision of the proposal for a corrigendum to draft Supplement 3 to the 02
series of amendments to Regulation No. 117 as a proposal for the 03 series of amendments based on documents GRB/2012/15 and GRB/2012/18.

GRB review of the text adopted by the Working Party on Brakes and Running Gear (GRRF) to add specific performance requirements for C2 snow tires to UN R117.

GRB revisions to the proposal adopted by the Working Party on Brakes and Running Gear (GRRF) at its seventy-second session in order to add specific performance requirements for C2 snow tires.

Draft supplemental documents to accompany the submission of the proposed
global technical regulation on pneumatic radial tyres for passenger and light truck (commercial) vehicles.

Amendments to the proposed structure and draft preamble to establish a global technical regulation (GTR) for new radial pneumatic tyres as agreed during the 13th Ad-Hoc Informal Working Group Meeting for a GTR on Tyres of 29 June 2012.

Editorial corrections proposed by the ETRTO, JATMA and RMA to the draft gtr on tyres.

Proposal to include wet grip adhesion provisions for C2 and C3 tyre categories.
