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

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;
2. correct the wording from “speed category symbol” to “speed symbol” (as defined in para. 2.33);
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 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 correct the text where the word “tyres” was inadvertently omitted from Paragraph 2.1.

Proposal for minor editorial corrections to the text.

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 to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation. The proposal offers four options to ensure appropriate approvals of LKAS and related CSF systems until such time as more precise requirements can be defined:

• Option 1 and option 2: Not to grant any type approvals for corrective steering functions until detailed technical requirements for CSF are incorporated into this Regulation.
• Option 3: Amend the definition of CSF as proposed in this document.
• Option 4: Amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1 as proposed in this document.

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 to delete a redundant requirement. The paragraphs 2.2. and 2.2.1. are superfluous since paragraph 5.2.2.13. already requires all O4 trailers to be equipped with Anti-lock Braking Systems (ABS) of Category A.

UN R55 informal group proposal for:

1. An amendment for the separation of the procedures to verify towable mass from the procedure of setting and certifying performance values;
2. An amendment that adds procedures to verify towable mass for vehicle combinations that have hitherto not been accounted for in the Regulation;
3. Amendments that adds integrated fixing points for secondary couplings;
4. An amendment that clarifies the procedure to identify worst cases for certification testing;
5. Amendments that removes typos in the current Regulation.

Proposal to add specifications for tyre sizes 33×11.50R20LT, 35×11.50R17LT, 37×13.50R26LT, 36×15.50R20LT and 40×15.50R26LT.

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.

Regulation No. 106 contains standardized tyre sizes which often need to be updated in line with technological 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 newly 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 correct a type in Annex 7- Appendix 2, Part 2, Paragraph 5 where the snow group index should read “1.00”, not “100” as appeared erroneously in the adopted text.

Proposal to amend the annex on complex electronic systems, in particular, to require auditing of the methodologies used to ensure system safety at both concept and system level. Concept level specifically requires consideration of interaction with other vehicle systems.

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;
