Responses to the IWVTA group questionnaire sent to Contracting Parties to the 1958 Agreement in order to determine readiness to apply the international whole vehicle type approval system (UN Regulation No. 0) and to raise any issues that might impede its development and use.

Review of research program that quantified differences in tire noise levels between the tire population on sale before and after revision of tire regulation in 2009 (Regulation (EC) No 1222/2009).

Clarifications and corrections to document GRRF/2014/26 which proposes to alter the marking requirements of UN R54 to replace the PSI Index by the inflation pressure in kilopascals (“kPa”) and to add the possibility to put the “LT” marking as a prefix or suffix to align the requirements with current practice for C2 tyres with metric size designation.

European countries are considering new requirements to require the fitment of snow tyres for use in severe snow conditions on specific axles of heavy duty vehicles. New tyres are approved under UN R117; however, a large percentage of heavy duty vehicles are fitted with retreaded tyres which are outside the scope of UN R117. This proposal would transpose the relevant requirements for new snow tyres into UN R109 in order of avoid the exclusion of retreaded tyres from such applications/markets.

Proposed amendments to update the documents, especially with reference to obsolete deadlines and timelines, in light of the recent finalization of the GTR text.

Proposal to clarify the inflated run-flat tyres are within the scope of this regulation while uninflated run-flat tyres fall exclusively under UN R64 and to remove references to UN R64 since this regulation and UN R64 exist as independent parallel tyre regulations. The proposal seeks to improve the wording, including to align more closely with EU Regulation (458/2011).

This proposal was prepared by OICA and is based on the existing UN Regulation No. 64. It is aimed at moving the Tyre Pressure Monitoring System provisions into a separate Regulation.

Amendments to document GRRF/2013/20 (proposal to include ATV tires in the motorcycle and moped tire regulation in order to enable the type approval of tires designed to equip quadricycles covered by the new Regulation (EU) No. 168/2013).

Proposals to modify UN Regulations 10 and 14 to address requirements under Australian law.

OICA strongly supports the German proposal and seeks clarification of certain points.

Proposal to delete references to tire-pressure monitoring systems under UN R64 (with the intention to establish them as a stand-alone regulation). This document presents only the amendments and complements the earlier document GRRF-78-38 that presented the consolidated version of UN R64 amended as proposed here.
