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

36. The expert from ETRTO proposed ECE/TRANS/WP.29/GRRF/2016/39 introducing updates to Annex 5.

37. GRRF agreed with the proposals above (see paras. 35-36) and requested the secretariat to keep the documents on the agenda of its January 2017 session.

35. The Chair recalled that GRRF already supported ECE/TRANS/WP.29/GRRF/2016/39 and that this document was kept on the agenda, awaiting other proposals to be considered at this session.

39. GRRF requested the secretariat to submit the adopted proposals ECE/TRANS/WP.29/GRRF/2017/9 amended by Annex VI (based on GRRF-83-23 and GRRF-83-15) as well as ECE/TRANS/WP.29/GRRF/2016/39 as draft Supplement 15 to Regulation No. 106 (Agricultural tyres) to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.

Revised version of the proposal to include UN R106 tyre dimensions in a Mutual Resolution on tyre sizes. The amendment to the table listing the allowed nominal rim diameters (d) is needed to allow the approval of standardized sizes which exist and are already on the waiting list for type approval.

36. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2017/5 and ECE/TRANS/WP.29/GRRF/2017/6 as amended by GRRF-83-11 and GRRF-83-12, proposing to introduce new tyres size usually listed in Annex 5 in a new Resolution, aimed at simplifying the update of this annex as well as reducing the number of amendments. GRRF noted that Annex 5 was containing non-metric tyre sizes not in line with the general formulae contained in the Regulation; therefore, GRRF wondered whether the right approach would be to introduce the appropriate formulae in the Regulation instead of continuously updating Annex 5. The expert from ETRTO agreed to address this proposal and to submit, if suitable, revised proposals for consideration at the next session.

Revised proposal for a “Mutual Resolution on dimensions of tyres of certain size designations”.

The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2017/5 and ECE/TRANS/WP.29/GRRF/2017/6 as amended by GRRF-83-11 and GRRF-83-12, proposing to introduce new tyres size usually listed in Annex 5 in a new Resolution, aimed at simplifying the update of this annex as well as reducing the number of amendments.

The expert from ETRTO agreed to address this proposal and to submit, if suitable, revised proposals for consideration at the next session.

Regulation No. 106 contains standardized tyre sizes, which often need to be updated, following the technical progress. In order to accelerate the update process of the Regulation and limit the number of amendments, it is proposed to insert in a new Resolution the standardized sizes and to refer to this Resolution in Annex 5. As a temporary solution to assess the effectiveness of such proposal, the Annex 5 of Regulation No. 106 will be kept as it is with no further updates. 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.

Proposal to add tyre and rim dimensions and to add a diameter code ‘d’ of 28.5 (Please note that the “28.5.5” shown in the table is a typo and should be “28.5”).

37. The expert from ETRTO presented GRRF-83-15 with new tyres sizes to be included in Annex 5. GRRF adopted the proposal.

39. GRRF requested the secretariat to submit the adopted proposals ECE/TRANS/WP.29/GRRF/2017/9 amended by Annex VI (based on GRRF-83-23 and GRRF-83-15) as well as ECE/TRANS/WP.29/GRRF/2016/39 as draft Supplement 15 to Regulation No. 106 (Agricultural tyres) to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.

Proposal to amend the transitional provisions of the formal proposal to update UN R106 (GRRF/2017/9).

38. The expert from ETRTO presented a revised proposal ECE/TRANS/WP.29/GRRF/2017/9 with provisions which were already supported at the last session. He introduced the revised transitional provisions related to new marking requirements. The experts from EC and UK proposed an alternative wording (GRRF-83-14). Both proposals received several comments. Therefore GRRF agreed to adopt the agreed provisions that would not be subject to transitional provisions and to remove the others, as reproduced in GRRF-83-23.

Amendment, per GRRF discussions, to remove the proposal to require the use of kPa markings and the related transitional provisions from the broader set of amendments to UN R106 proposed in document GRRF/2017/9.

Proposal to:

1. Align definitions and contents of paragraphs with the other tyre regulations (UN R30, R54, R117, etc.);
2. Include a definition of “Manufacturer” extracted from the resolution “R.E.3”;
3. Adopt a common definition and use of the terms “Manufacturer’s name”," Brand name", “Trademark”, “Trade description” and “Commercial name” and their links;
4. Clarify which markings shall be moulded on both sidewalls of the tyre; and those which shall be moulded on one sidewall only;
5. Add information in the certificate to clarify the relationship with the certified products;
6. 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;
7. Eliminate redundant marking requirements with the requirement for “@kPa” markings effective from 1 September 2017;
8. Clarify the inflation pressure to be used for measurements and tests and related tyre markings;
9. 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;
