| Proposal for draft corrigendum to UN Regulation No. 108 |
| Reference Number: GRRF/2017/25 |
|
Proposal to align the Russian text with the original English text. In the English versions, the title of Annex 1 (Communication concerning the approval or extension or refusal or withdrawal of approval or production definitely discontinued of a retreading production unit pursuant to Regulation No. 108) is essentially identical to that use for Annex 1 of UN R109. Therefore, this proposal amends the title of Annex 1 in the Russian version of UN R108 to coincide with that of the Russian version of Annex 1 in UN R109. |

| Tyre category definitions and requirements for tyre use on roads under winter conditions |
| Reference Number: GRRF-83-05 |
|
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. |
