Proposal to remove tire-pressure monitoring provisions from UN R64 to enable the use of UN R64 within the International Whole Vehicle Type Approval system.

Revised text proposing a stand-alone TPMS regulation based upon the provisions currently in UN R64.

Proposal for an alternative to the proposal (document GRRF/2015/9) to restore transitional provisions incorrectly deleted by Supplement 6 to the 02 series of amendments.

This document represents the result of analysis of the existing (document GRRF/2015/12) and newly introduced (GRRF-79-09) transitional provisions concerning the separation of tire-pressure monitoring systems from UN R64.

Proposal to include material characteristics of the tire tread in the technical requirements since the definition of “snow tyre for use in severe snow conditions” refers both to tread compound and tread pattern.

This proposal aims to align the UN Regulation 106 with international standards (ETRTO, T&RA and ISO 4351-2 table 2). This proposal will also avoid any possible misunderstanding for the application of the EC Regulation 167/2013 that refers to UN R106.

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.

This proposal is an alternative to that represented in document GRRF/2015/9 and GRRF-79-19.

The overall aim of the study is to propose policy options concerning the use of tyres for improvement of traffic safety. Centrally to this, is the idea that end users need to make the correct assessment in relation to the tyre condition in order to achieve a level of safety as high as possible. Within this context, the tyre condition is considered in relation to technical elements (tyre inflation pressure, tyre tread depth, tyre damage, tyre age, and meteorological influences) and one information element (driver awareness). The study addresses the topics of tyre usage and the impact on road safety (which are the potential safety improvements related to tyre usage from a technical perspective) and how can road users be supported to use tyres that have a better safety performance by policy options.

Status of work on adapting current UN Regulations for use in the whole vehicle type approval system. “List B” covers UN Regulations that should be included in the approval system but which require some adjustments before they can be transferred to the “List A” of regulations confirmed for inclusion in the whole vehicle approval.

This document proposes to replace an item in the information document for IWVTA. The reason is that the previous entry “maximum hourly output” is not defined anywhere in the UN Regulations whereas the newly proposed item “maximum 30 min. power” is defined in UN R85.

Proposal for a working group on the “Administration of the International Whole Vehicle Type Approval System and the Exchange of Type Approval Data” to oversee the implementation and administration of the IWVTA and DETA systems.
