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.

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.

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

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”).

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 correct the paragraph numbering of the original proposal for amendments to Regulation No. 54 contained in document GRRF/2017/18. The introduction of new paragraphs by Supplement 21 and the separation of paragraph 3.1. into subparagraphs 3.1.1. and 3.1.2. result in the proposed paragraph 3.1.12. being renumbered as 3.1.13.

Discussion of run-flat tyres and extended mobility tyres (EMT) in support of a general proposal to establish approval procedures for EMT under UN R30 and include EMT as “emergency mobility equipment” under UN R64. The proposal makes reference to recent activity on ISO 16992 regarding EMT test protocols.

Introductory statement to document GRRF-86-04 proposing amendments in order to provide a legal approval framework for extended mobility tyres under UN R30 and their recognition as “emergency mobility equipment” under UN R64.

Possible scenarios for developing regulatory provisions for snow tyres under UN tyre regulations.

Correction of a cross-reference error in the original documents GRRF/2018/5 and GRRF/2018/11.

Pursuant to Supplement 21 to UN R54 replacing PSI with kPa to indicate tyre inflation pressures, UN R109 requires updating. This proposal would allow both markings under UN R109 because the life cycle of the carcasses spans several years.

Proposal to correct a mistake in Supplement 17 to UN R75 (adopted document WP.29/2017/8). Annex 7, Paragraph 1.2., Footnote 1 should refer to UN R54, not UN R106.

Proposal to amend footnotes in Annex 5, Part II, Table B in order to clarify categories of use.

TyreGTR informal group presentation of Amendment 2 to the GTR on tires.

Proposal to add a paragraph to define the purpose of the “SS” marking introduce by the amendments to UN R106 on agricultural and related off-road tyres.

Submission from France proposing changes in the definition of the measuring rim for C1, C2 and C3 tyres.

Proposal to align the definition of the temperature correction coefficient “K” in UN Regulation No. 117: 02 series of amendments with ISO 28580. The issue is linked to tire categories: ISO refers only to load index while UN R117: 02 series refers to class C1, C2 and C3 tires.

European Tyre and Rim Technical Organisation (ETRTO) proposal to amend the snow test method for C3 tyres in order to prescribe the wider of the possible speed ranges.

Proposal to correct the omission of the rim-diameter code 25 for the calculation of metric-designated tyres (this rim code appears in Annex 5, Table 7 for code designated tyres).

Text prepared by the European Commission (EC), France and European Tyre and Rim Technical Organisation (ETRTO) in order to introduce wet grip provisions and testing procedures for tyres of categories C2 and C3.

Supplement 2 to the 02 series of amendments to Regulation No. 117 (Document WP.29/2012/54) as adopted at the June WP.29 session contained a typo where the snow temperature range for the snow grip test should be ‐4°C to ‐15°C, but the ‘minus’ sign was omitted before the first figure.

Proposal to incorporate additional tire sizes within the regulation for commercial vehicle tires sold in countries requiring type approval according to UN Regulation No. 54.

Proposal to include ATV tires in the motorcycle and moped tire regulation in order to enable the type approval of tires designed to equip quadricycles covered by the new Regulation (EU) No. 168/2013 of 15 January 2013 on the approval and market surveillance of two- or three-wheel vehicles and quadricycles (L category vehicles). These tires may also equip some agricultural tractors (SbS vehicles) covered by the new EU Regulation.

Text prepared by the European Tyre and Rim Technical Organisation (ETRTO) to clarify the test procedure of the second load/speed performance test used for tires designed for speeds above 240 km/h for tires (as identified by the letter code “V” or “Z” in the size designation).

Text prepared by the European Tyre and Rim Technical Organisation (ETRTO) to remove All Terrain Vehicles (ATV) tires from UN Regulation 106 on agricultural tires.

Text prepared the European Tyre and Rim Technical Organisation (ETRTO) to introduce new tire sizes.

Proposal by the European Tyre and Rim Technical Organisation (ETRTO) to insert a new marking provision and, under “categories of use”, a definition for construction application (Industrial tractor) tyres into UN R106.

Proposal for a new regulation for the approval to tires installed on a vehicle. This regulations is proposed for use within the International Whole Vehicle Type Approval system in order to ensure proper tire fitment on a vehicle under IWVTA evaluation. This document supersedes GRRF-75-20.

Proposed changes from the ETRTO to clarify the communication form in Annex 1.

Proposal to alter the marking requirements after November 2016 to replace the PSI Index by indicating the inflation pressure in kilopascals (“kPa”) and to add the possibility to put the “LT” marking as a prefix or suffix to align the requirements with current practice for C2 tyres with metric size designation

Proposal from the European Tyre and Rim Technical Organisation (ETRTO) in order to add new tyres for light commercial vehicles (high flotation tyres) in Annex 5 of UN Regulation No. 54.

Proposal to permit the “LT” marking as a prefix or suffix to align the requirements with the current practice for C2 tyres with metric size designation. The proposed text for a prefix is in line with the latest draft of the gtr on tyres. The proposed text for a suffix is necessary for tyres designed to Japan Automobile Tyre Manufacturers Association (JATMA) standards.

Proposal to restore transitional provisions incorrectly deleted by Supplement 6 to the 02 series of amendments.
