In addition, the proposal corrects the use of uppercase letters to denote dimensions where lowercase letters had been inserted.
GRRF/2017/4 | Proposal for amendments to Regulation No. 54 Proposal to add specifications for tyre sizes 33x11.50R20LT, 35x11.50R17LT, 37x13.50R26LT, 36x15.50R20LT and 40x15.50R26LT.

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.
