Add a generic reference to the Consolidated Resolution on the Construction of Vehicles (R.E.3) in footnote 5.
align the categories of use to “normal tyre”, “snow tyre” and “specialuse tyre” in line with UN R30 and 54, to introduce a definition of “normal
tyre” and consequently make use of the terms “snow tyre” and “special-use tyre” that are already defined
reformat Annex 5, Table 7 to present the tyre-size designations in a consistent way and to provide explicitly that tyre-size designations from this table may also be used for tyres in bias-beltedvstructure
Include the suffix “M/C” that is defined as mandatory for motor-cycle tyres with rim diameter code 13 and above in the figure illustrating the sidewall markings in Annex 3 and to present the markings in a clearer way
Add provisions for the dimensional requirements of moped tyres
Add a factor for the centrifugal radius of snow tyres and special-use tyres with a speed category above 210 km/h
Give the footnotes in the main body of the regulation an unequivocal number to avoid confusion when referencing to a particular footnote
Include several editorial corrections to increase the consistency of the text (e.g. consistent use of the terms defined in section 2, such as “tyre-size designation”, “load-capacity index”, “speed-category symbol”).
