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 prepare an amendment to UN Global Technical Regulation (GTR) No. 16 on tyres in order to introduce provisions concerning wet grip performance, rolling resistance, and qualification of tyres for use under severe snow conditions in accordance with the same provisions introduced recently into UN Regulation No. 117.

Status of the draft text to introduce provisions for tyre rolling resistance and snow performance testing into the global technical regulation on tyres.

Proposed additions to the Statement of technical rationale and justification in GTR 16 (tyres), especially to clarify application and future development of the regulation.

Proposal is to align GTR 16 with technical progress, incorporating new provisions for wet grip performance, rolling resistance and qualification for use at severe snow conditions both for passenger car (PC) and light truck / commercial (LT/C) tyres (as were recently adopted within UN Regulation No. 117). The proposal also includes updates from relevant FMVSS and UN Regulations Nos. 30 and 54.
