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.

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.

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.

Proposal to separate provisions for tire-pressure monitoring systems from UN R64.

Proposed text for a new UN Regulation that would comprise all the tyre-pressure monitoring system (TPMS) provisions presently contained in UN Regulation No. 64. This separation is proposed to facilitate the use of UN R64 in the international whole vehicle type approval system under development.
