Proposal for a revised UN R64 that removes the provisions for tyre-pressure monitoring systems (TPMS) (to be reproduced in a new separate regulation) in order to facilitate the application of UN R64 within the International Whole Vehicle Type Approval system.

Proposal for a separate TPMS regulation, removing the Tyre Pressure Monitoring System provisions out of UN R64, in order to facilitate the establishment of the International Whole Vehicle Type Approval system. It is based on document GRRF/2015/13 taking into account the comments received at GRRF-78.

Draft proposal for a revised UN R64, removing the type-pressure monitoring systems provisions, in order to facilitate its use in the International Whole Vehicle System.

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.

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 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.
