German position paper arguing for greater objectivity and clarity over the use of the proposed “M+S”, “M.S”, “M&S”, and “Alpine” symbol with regard to “snow tyres” and “snow tyres for use in severe snow conditions”.

Proposal to maintain a wet grip index of 0.65 for class C3 normal tires and regular snow tires under the discussions to establish wet grip provisions and testing procedures for category C2 and C3 tires.

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.

Assessment of ISO 4287-1997 and ISO 25178-2016 (Part 1:2016 or 25178 series) regarding the reference standard for the roughness measurement.
