Proposal to

1. change measurement units for drum speed in Annex 7 from min^-1 to km.h^-1 to align the requirements with other tyre regulations;
2. correct wording from “speed category symbol” to “speed symbol” (as defined in para. 2.33);
3. correct wording from “load capacity index” to “load index” (as defined in para. 2.32);
4. correct a reference to para. 3.2.13. of the Regulation in Annex 7, Appendix 1;
5. correct a boundary value of load index in Annex 7, Appendix 1;
6. delete in paragraph 2.1 in Annex 7, the possibility to use the 2.0 m drum diameter to perform the endurance test; and
7. align the text of Annex 10 with Annex 7 of UN R117 pursuant to the adoption of Supplement 5 to the 02 series of amendments to that regulation.

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).

Revised proposal, based on document GRRF/2016/38 and revising GRRF-82-24, to:
a) Align definitions and contents of paragraphs with the other tyre regulations (UN R30, R54, R117, etc.);
b) Include a definition of “Manufacturer” extracted from the resolution “R.E.3”;
c) Adopt a common definition and use of the terms “Manufacturer’s name”," Brand name", “Trademark”, “Trade description” and “Commercial name” and their links;
d) Clarify which markings shall be moulded on both sidewalls of the tyre; and those which shall be moulded on one sidewall only;
e) Add information in the certificate to clarify the relationship with the certified products;
f) Align definitions with Regulation EU 167/2013 which defines vehicles in category S as “interchangeable towed equipment” and includes tread patterns for ‘implement traction tyres’ that consist of blocks rather than lugs or cleats;
g) Eliminate redundant marking requirements;
h) Clarify the inflation pressure to be used for measurements and tests and related tyre markings;
i) Align the current rules for calculating the dimensional limits in accordance with ISO, all major tyre standards, and as proposed for UN R30, R54, and R75.

Proposal to correct paragraph number references due to the recent renumbering of definitions.

Correction of the paragraph numbering pursuant to the adoption of Supplement 21 and deletion of a redundant note at the end of paragraph 6.1.5.3.3.

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.

Regulation No. 106 contains standardized tyre sizes which often need to be updated in line with technical progress. In order to accelerate the update process of the Regulation and limit the number of amendments, it is proposed to establish a new Resolution on standardized sizes and to refer to this Resolution in Annex 5.

Proposal to remove the technical content in Annex 5. This content would be incorporated into a new Resolution on Tyre Sizes as proposed in document GRRF/2016/46.

Proposal for a minor editorial correction to the text. Paragraph 4.8. should read “Annex 2 to this Regulation gives an example of approval marks.” The current text refers to “examples” where there is only one provided.

Proposal for minor editorial corrections to the text.

Proposal to correct the text where the word “tyres” was inadvertently omitted from Paragraph 2.1.

Proposal to clarify provisions for 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. The proposal also corrects tables and figures for the use of lowercase letter to denote tyre dimension specifications.

Proposal to amend Annex 7 (based on the documents ECE/TRANS/WP.29/GRRF/2015/39 and GRRF-80-16 from Slovakia) and Annex 10. This proposal would:

1. change measurement units for drum speed in Annex 7 from min-1 to km.h-1 to align the requirements with other tyre regulations;

3. correct the wording from “load capacity index” to “load index” (as defined in para. 2.32);
4. correct a reference to para. 3.2.13. of the Regulation in Annex 7, Appendix 1;
5. correct a boundary value of load index in Annex 7, Appendix 1;
6. delete in paragraph 2.1 in Annex 7, the possibility to use the 2.0 m drum diameter to perform the endurance test.

In Annex 10, the proposal aligns the text with Annex 7 of UN R117, 02 series of amendments, Supplement 5.

Proposal to amend Annex 5 with regard to Improved Flexion (IF) tyres and Very high Flexion (VF) tyres.

Proposal to:
a) Align definitions and contents of paragraphs with the other tyre regulations (UN R30, R54, R117, etc.);

After a trial period of approximately two years and upon confirmation of effectiveness, the complete Annex 5 of Regulation No. 106 would be transferred to this Resolution on Tyre Sizes.
