Germany reviews problems with applying UN specifications for the marking of winter tyres, covering disparities in definitions and performance requirements across the tyre regulations (UN R30, R54, R75, R106, R108, R109 and R117). Therefore, Germany proposes that GRRF work to resolve these disparities and offers two possible solutions: 1) Introduce the definition of "Snow tyre for use in severe snow conditions” and the related performance and marking requirements established under UN R109 and R117 into UN R30, R54, R75, R108, and (possibly) R106; 2) Amending UN R117 to extend the scope of its snow performance criteria to additional tyre classes and categories, such as special tyres (POR, MPT), all terrain (AT) tyres, and retreaded tyres for passenger cars.

Updated proposal to correct paragraph number references due to the recent renumbering of definitions based on document GRRF/2016/33.

Proposal to allow for the case of a tyre designed for a special application that also fulfills the requirements for a snow tyre such that the tyre, at the manufacturers initiative, shall be marked with the inscription M+S or M.S or M&S while remaining in the category of use “special use tyre”. The proposal further adds “test laboratories” in the headline of paragraph 12. as quoted in subparagraph 12.1. in document WP.29/2016/51 as adopted during the June WP.29 session with the aim of harmonizing the tyre regulations.

Discussion paper outlining concerns over particulates originating from tire erosion and suggesting a need for global regulatory provisions to limit such environmental risks.

Proposal adopted by the GRRF to harmonize definitions and marking requirements of UN R30 with the new 02 series of amendments to Regulation No. 117 and clarifying the requirements for the load/speed performance test and to cover regulatory regulatory markings for “temporary uses spare tyres”.

ETRTO proposals to align the definitions in UN R30, R54 and R117 (documents GRRF/2011/13 and 14) raised comments from France (document GRRF-71-31). This document offers a basic “snow tyre” definition/markings plus a more precise definition/markings for tyres used in severe snow conditions.

The proposal harmonizes the definitions and marking requirements of UN R30 with the new 02 series of amendments to UN R117 and the latest proposal for amendment to UN R117 related to the snow tyre definitions as proposed by the informal group “snow tyre”. This document supercedes GRRF/2011/13.
