World Forum for the Harmonization of Vehicle Regulations | Session 160 | 25-28
Jun 2013
[The World Forum agreed to keep this proposal on the agenda for consideration at its November 2013 session pending reconfirmation of the proposed limit values by GRRF at its September 2013 session.]
Working Party on Brakes and Running Gear | Session 75 | 17-19
Sep 2013
26. The expert from ETRTO presented GRRF-75-02, justifying the wet grip limit values for C3 tyres specified in ECE/TRANS/WP.29/2013/66. Following a tour de table, the Chair noted that half the experts were in favour of amending the proposed limits for normal and traction tyres whilst retaining the proposed limits for snow and special use tyres, while the other half were in favour of maintaining those proposed in ECE/TRANS/WP.29/2013/66. The GRRF Vice-Chair volunteered to lead a discussion with interested experts on a proposal for GRRF at its next session. GRRF preferred to postpone the vote by WP.29 and AC.1 on ECE/TRANS/WP.29/2013/66 until their June 2014 sessions.
World Forum for the Harmonization of Vehicle Regulations | Session 161 | 12-15
Nov 2013
32. The Chair of GRRF reported that GRRF was still seeking a consensus proposal on new wet grip limits for tyres of category C3 in ECE/TRANS/WP.29/2013/66 (Supplement 5 to the 02 series of amendments to UN Regulation No. 117) and proposed WP.29 and AC.1 to defer the vote.
Working Party on Brakes and Running Gear | Session 76 | 17-21
Feb 2014
24. Recalling the purpose of ECE/TRANS/WP.29/2013/66, the Chair of GRRF stressed that WP.29 was expecting GRRF to conclude its deliberation about the wet grip limit values. The GRRF experts introduced their positions (GRRF-76-05, GRRF-76-07, GRRF-76-08, GRRF-76-11, GRRF-76-12, GRRF-76-26, GRRF-76-27, GRRF-76-28). The expert from the EC reported on the concerns expressed by the Directorate-General for Mobility and Transport of the European Commission (DG Move). GRRF confirmed the limit values proposed in para. 6.2.2. for Tyres of C2 category and agreed to amend the proposed limit values in para. 6.2.3. for Tyres of C3 category in ECE/TRANS/WP.29/2013/66. GRRF requested the secretariat to submit this amendment as reproduced in WP.29-162-05 to WP.29 and AC.1 for consideration at their March 2014 session.
24bis. The expert from the Russian Federation presented GRB-59-02 proposing a tyre rolling resistance test results evaluation using a mathematical algorithm, to be added as an alternative to the existing one in the text of the Regulation. He also presented the results of a validation study of the proposed algorithm for tyres of the C1 category performed in France, in cooperation with the Russian Federation (GRB-59-07 and GRB-59-08). GRRF noted that this proposal may be submitted by GRB to WP.29 as a supplement to UN Regulation No. 117. GRRF recommended further steps for a better understanding of the proposed method’s sensitivity, suggesting: (i) extending the validation study for tyres of categories C2 and C3 and (ii) verifying the application of the proposed alternative in the conditions of the conformity of production. The GRRF Chair invited the experts to provide their comments on the proposal to the GRB secretariat with a copy to the expert from the Russian Federation.
World Forum for the Harmonization of Vehicle Regulations | Session 162 | 11-14
Mar 2014
55. The World Forum considered the pending proposal for amendments to Regulation No. 117 listed under agenda item 4.12.3 (document ECE/TRANS/WP.29/2013/66) and recommended its submission to AC.1 for voting, subject to the correction of para. 47 below (see WP.29-162-05).
56. Page 1, the title, replace “Supplement 5” by “Supplement 6”. Page 2, paragraph 6.2.3, correct the wet grip index G for normal tyres other than traction tyres to read 0.80.
[The proposal was adopted as amended as “Supplement 6 to the 02 series of amendments to UN Regulation No. 117” by a vote of 36 in favor and none either opposed or abstaining.]

Description: Proposal to revise the limits for rolling resistance and wet grip, to address tyres for vintage vehicles, to revise the definition for special-use C1 tyres, and to set the wet grip index threshold at 0.80 for class C1 tyres with a nominal aspect ratio equal to or less than 40, a section width equal to or higher than 235 mm and suitable for speeds equal to or greater than 300 km/h and for class C1 all terrain and special use tyres. The proposal also introduces the kworn factor in a new para. 3 in Annex 9 to address wet grip of C2 and C3 tyres in a worn state (see GRBP-75-26-Rev.1 for concept), provisions to allow the type approval of special use tyres that fulfil the requirements for snow performance as laid out in Annex 7, and a new definition of traction elements to characterize traction tyres.

Document Reference Number: WP.29/2023/6
|
Description: Proposal to introduce provisions to allow type approval of special use tyres that fulfil the requirements for snow performance as laid out in Annex 7, to improve precision of the test procedures for measuring the wet adhesion of tyres in a worn state by using a moulded SRTT16 reference tyre (instead of a buffed tyre), to introduce new transitional provisions related to this change, to extend corrections already made to the 02 series to the 03 series and make additional editorial corrections, and to define the range for tyre inflation vis-à-vis rim size to reduce uncertainties in measuring tread depth. The proposal introduces the tyre reference F3611-22 per document GRBP/2023/2 submitted to the January 2023 session of GRBP.
