Pursuant to the addition of a new speed symbol for forestry tyres, this proposal would add a bonus loads column for A6-rated tyres to Annex 7-Part D. The proposal also corrects the tables concerning “Agricultural implement tyres – Normal section sizes”.

UN R106 | Revision 2 | Amendment 4 (2017)
22 Feb 2017 2017-05-31 17:50:03 UTC 2 4 00 series of amendments | Supplement 14 Based upon the adopted proposal: WP.29/2016/59

Proposal to align UN R106 with international standards (ETRTO, T&RA and ISO 4351-2 table 2) with regard to Improved Flexion (IF) tyres and Very high Flexion (VF) tyres to add load indexes to the table in the Annex 4 to keep up with the technical evolution of tyres. This proposal also clarifies the application of EC Regulation 167/2013 which refers to UN R106.

UN R106 | Revision 2 | Amendment 5 (2018)
27 Apr 2018 2018-05-10 08:58:41 UTC 2 5 00 series of amendments | Supplement 15 Based upon the adopted proposal: WP.29/2017/70

Proposal to introduce new tyres size usually listed in Annex 5 in a new Resolution in order to simply maintenance of this annex and reduce the volume of amendments. This proposal includes changes regarding Improved Flexion (IF) tyres and Very high Flexion (VF) tyres. The proposal harmonizes with EU framework legislation for agricultural vehicles.

UN R106 | Revision 2 | Amendment 6 (2019)
16 Jan 2019 2019-01-25 13:10:52 UTC 2 6 00 series of amendments | Supplement 16 Based upon the adopted proposal: WP.29/2018/57

Proposal to add tyre sizes and tyre classification codes common in the United States and standardised by the Tire and Rim Association, but needed under UN Regulation No. 106 in order to permit their type approval in conformity with Regulation EU 167/2013 for imported tyres. The proposal adds kPa marking specifications for use in measurements and tyre testing. The proposal further includes changes to the text and addition of tyre size designations to Annex 5 and Annex 7:

  1. Paragraph 2.33.2 deleted since new tables for IF and VF were added to Annex 7
  2. Paras 3.2., 3.2.2. and 5.4. modified because “tyres submitted for approval” cannot bear an approval mark until approved and the “only” as it is written can be misunderstood. Para. 3.2.2. was aligned to the wording in other UN Regulations. Reference to para. 3.3 in paragraph 5.4. is deleted because paragraph 3.3 does not refer to specific markings
  3. Para 6.1.2. amended to align the wording to the headers in Annex 5 and to correct the reference to the footnote
  4. Para 6.2.1. amended to restore the proper references after renumbering resulting from the latest Supplements
  5. The amendment of Annex 5, Table 5 adds the value for the overall diameter (D) in column (*) that applies to tyres marked with classification code “I-3”
  6. Annex 5, Table 6, Note 1 amended because most of the tyre sizes listed in the table, especially those identified by the “classification code I‐3” (i.e. Traction tread), are currently available in both versions: ‘implement’ to be used on agricultural machinery and ‘IND’ to be used on construction vehicles. The two types of tyres have the same type of size designation and the same dimensions. Therefore some manufacturers identify those tyres with the suffix ‘IND’ rather than with the suffix ‘IMP’ thus applying the variation of load capacity with speed as published in Annex 7 Part E. The reason for this proposal is to avoid a duplication of tables with a new table only replacing the suffix IMP with the suffix IND.
  7. The addition of the footnote to Annex 5, Table 7 answers the request by GRRF to introduce appropriate formulae in the Regulation instead of continuously updating Annex 5.
  8. References in Annex 7 corrected pursuant to the renumbering following the introduction of three new paragraphs in Supplement 15 approved during the 172nd session of WP.29.
  9. Annex 7, Part A amended to conform with Tire and Rim Association specifications for code designated diagonal tyres with speed symbol A8.
The proposal also adds a paragraph to define the purpose of the “SS” marking introduce by the amendments to UN R106 on agricultural and related off-road tyres.

UN R106 | Revision 2 | Amendment 7 (2019)
19 Nov 2019 2020-02-20 15:38:21 UTC 2 7 00 series of amendments | Supplement 17 Based upon the adopted proposal: WP.29/2019/5

Proposal to

  1. modify the scope with regard to Category S and R agricultural vehicles,
  2. modify the paragraph numbering (and related footnotes) to improve text clarity,
  3. to correct an error in Annex 5 Table 7 where “35×16” should read “36×16”,
  4. amend Annex 7 Part E to address variations of load-carrying capacity for tyres for construction applications (industrial tractors or skid-steers / mini-loaders) with speed category symbol “D”.

UN R106 | Revision 2 | Amendment 8 (2020)
2 Nov 2020 2021-01-03 18:50:56 UTC 2 8 00 series of amendments | Supplement 18 Based upon the adopted proposal: WP.29/2020/5

Proposal to:

  1. include the load variation with speed for IF and VF tyres in Table A of Annex 7
  2. introduce a new paragraph (2.18.13) and amend paragraph 3.1.9.and Annex 3,part D to reconcile contradictions
  3. clarify Annex 6 “Test method for measuring tyre dimensions” via references to other provisions
  4. Correct example in Annex 3, part C by introducing the dimension “b” for the tyre size designation, and
  5. Modify inflation pressure markings.

UN R106 | Revision 2 | Amendment 9 (2021)
8 Dec 2021 2022-10-23 13:31:21 UTC 2 9 00 series of amendments | Supplement 19 Based upon the adopted proposal: WP.29/2021/7

Proposal for alternative language regarding markings to avoid use of the term “moulded” which could be interpreted as a technical design restriction and to add a reference to “log-skidder” tyres.
