Tyre category definitions and requirements for tyre use on roads under winter conditions (Germany and BMDV)
Tyre category definitions and requirements for tyre use on roads under winter conditions
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.

Proposal for amendments to Regulation No. 54
Proposal to clarify the minimum heights for markings for tyres with nominal rim diameter codes ≥ 20 and nominal section width ≤ 235 and for tyres with nominal rim diameter codes < 20 and nominal section width > 235. In addition, the proposal corrects the use of uppercase letters to denote dimensions where lowercase letters had been inserted.
