Proposal for amendments to Regulation No. 54
Document GRRF-81-11
27 January 2016

Proposal to clarify the provisions for the minimum heights of 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 aligns the table on minimum marking heights to correspond with the related figure by using lowercase letters to denote dimensions in both (currently, the figure uses lowercase, but the table uses uppercase).
