Proposal to delete the term “Supplier of the tread used for retreading process”, to delete “material manufacturer” in favor of “material supplier”, to simplify the list of tyres classified as a tyre for use in severe snow conditions and/or as traction tyre, to introduce a paragraph clarifying that the supplier of tread material dedicated to the retreading of tyres categorized as special use tyres shall provide to the retreader the “void to fill ratio” pertinent to such tread material, to correct a reference to “Appendix 2” to refer to “Schedule 1” of the 1958 Agreement, to delete the field for “Extension No.” in the Communication form since the extension is already in the Approval number, and to align wording with UN R54.
