Proposal to allow for the case of a tyre designed for a special application that also fulfills the requirements for a snow tyre such that the tyre, at the manufacturers initiative, shall be marked with the inscription M+S or M.S or M&S while remaining in the category of use “special use tyre”. The proposal further adds “test laboratories” in the headline of paragraph 12. as quoted in subparagraph 12.1. in document WP.29/2016/51 as adopted during the June WP.29 session with the aim of harmonizing the tyre regulations.

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.

Proposal to:
a) Align some definitions and some contents of paragraphs with the other tyre regulations (Regulations Nos. 30, 54, 117, 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 the designation of the categories of use;
e) Remove the word “normal” in the definition of “Reinforced” tyre to avoid confusion
with the category of use “normal”;
f) Add some information in the certificate to the attention of the Type Approval
Authorities for making easier the relationship between this one and the products.

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

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 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 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.

WP.29 adoption of the new IWVTA regulation (UN Regulation No. 0) is anticipated for March 2017 with an entry-into-force the following October. This initial regulation (00 series of amendments) will include UN Regulations as they stand prior to September 2, 2017. However, a number of these regulations contain transitional provisions such that new versions will enter into force during the 12 months following this cut-off date. Therefore, this document (updated from the earlier version) proposes a list of such regulations that would be included in the 01 series of amendments to UN R0 to be submitted for adoption by WP.29 in November 2017. In concept, UN R0 would be updated with these “upgraded” versions of the UN Regulations.
