16. The expert from ETRTO reported on their ongoing assessment (GRBP-75-22) of the new definition of “radial tyre” that had been proposed by the experts from France and EC at the previous session (ECE/TRANS/WP.29/GRBP/2021/9). GRBP looked forward to the outcome of the ETRTO activities and expected that a final proposal would be submitted to the next session. The experts from the Netherlands and Russian Federation pointed out that the radial tyre definition may not necessarily cover new types of tyre structures and that adding a new subgroup of tyres with their own definition should be considered as an alternative.

17. GRBP recalled that, at its previous session, it decided to continue consideration of ECE/TRANS/WP.29/GRBP/2021/13 in view of other draft amendments to UN Regulation No. 54 (ECE/TRANS/WP.29/GRBP/72, para. 16). The expert from ETRTO tabled a proposal that aimed to consolidate the calculation of reference dimensions with that provided in United Nations Global Technical Regulation (UN GTR) No. 16 (ECE/TRANS/WP.29/GRBP/2022/6).
18. GRBP adopted ECE/TRANS/WP.29/GRBP/2022/6 and ECE/TRANS/WP.29/GRBP/2021/13, as amended by GRBP-75-31-Rev.2, and requested the secretariat to submit it for consideration and vote at the June 2022 sessions of WP.29 and AC.1 as draft Supplement 25 to the original series of amendments to UN Regulation No. 54.

Document Reference Number: WP.29-186-07

Description: ETRTO detected an issue in document ECE/TRANS/WP.29/2022/7 with the insertion of paragraph 3.5.1. that is the consequence of the alignment between UN Regulation No. 54 and UN Regulation No. 109. This new requirement regarding the marking position in the sidewall for retreaded tyres is creating a burden for the retread industry that will potentially need to adapt all their moulds accordingly, without considering transitional provisions.

78. The World Forum considered the draft amendments under agenda items 4.6.1, 4.6.3, 4.6.4 and 4.6.6 to 4.6.8. and recommended their submission to AC.1 for voting.
79. The World Forum recalled that it had accepted the request of the GRBP Chair to postpone to the June 2022 session consideration of the draft amendments under agenda items 4.6.2 and 4.6.9 (see para 60. above).
80. The representative of ETRTO proposed a modification to the draft amendments in ECE/TRANS/WP.29/2022/7 under agenda item 4.6.5 (WP.29-186-07). The representatives of the European Commission and the United Kingdom of Great Britain and Northern Ireland commented on the ETRTO proposal. Based on the received comments, the World Forum requested ETRTO to revise WP.29-186-07 and decided to postpone consideration of the draft amendments in ECE/TRANS/WP.29/2022/7 to the June 2022 session. In the interim, the World Forum requested the secretariat to arrange a written consultation of GRBP experts on the ETRTO proposal.

16. The experts from the European Commission introduced a new 04 series of amendments to UN Regulation No. 117 (ECE/TRANS/WP.29/GRBP/2022/12). The expert from ETRTO proposed further modifications (GRBP-76-23 and GRBP-76-32). GRBP adopted ECE/TRANS/WP.29/GRBP/2022/12, as amended by GRBP-76-23 and GRBP-76-32, subject to the removal of the square brackets, and requested the secretariat to submit it for consideration and vote at the March 2023 sessions of WP.29 and AC.1 as the draft new 04 series of amendments to UN Regulation No. 117.

28. GRBP noted that all above amendments to the 03 series of amendments to UN Regulation No. 117, i.e. draft Supplement 1 to the 03 series, should also be included into the draft new 04 series of amendments to UN Regulation No. 117.
29. To facilitate consolidation of amendment proposals according to their series of amendments of UN Regulation No. 117, the expert from ETRTO prepared a summary of all relevant official and informal documents (GRBP-76-38). In this context, GRBP expressed a general concern about the late arrival of a large number of informal documents, impeding their proper consideration by experts from contracting parties.
30. GRBP noted that the consolidated amendment proposals to the 02, 03 and 04 series of amendments of UN Regulation No. 117 would be prepared in December 2022 and submitted to the March 2023 sessions of WP.29 and AC.1. In the interim, GRBP agreed to check these consolidated documents for errors at its next session in February 2023.

UN R54: Proposal for amendments
Document Title: UN R54: Proposal for amendments

Description: Proposal to address the following:
1. “Special use” tyres with nominal rim diameters larger than those listed in the present table (rim diameters up to 42, section widths up to 750 mm and overall diameters over 2 meters) and with speed symbols F and above have been announced in the European market as original equipment of N3G “special purpose vehicles” (i.e., special high speed self-propelled vehicles for agricultural and forestry use, like wood choppers).
2. Existing multi-purpose tyres (MPT) (classified as “special use tyres” as per paragraphs 2.5.3. and 3.1.13.), already type approved since years, have a tread pattern with lugs or cleats in addition to those with blocks, as evidenced by the attached slide showing some examples. It is proposed to amend paragraph 6.3.1. by clarifying that lugs and cleats are possible shapes of the mentioned blocks.
3. Testing tyres with very large overall diameters, sometimes over 2 m, on a test drum with a diameter of 1.70 m ± 1 % would be unpracticable. For practical reasons most of those
tyres are regularly tested on drums with a diameter of 3 m or even larger. The proposal carries equivalence provisions from UN R106 to justify the equivalence of the test method as required by Annex 7 in point 4 “Equivalent test methods" and clarifies based on UN R117 the formula already used indirectly.
4. Some commercial vehicles are often used in the market at a reduced speed of 70 km/h with a load-capacity of the tyres increased as per load/speed combination defined in the table of Annex 8. The proposal would allow use of the speed category symbol E (but restrict it to “additional service description”) to provide this information.
5. Considering that 32 km/h is already a floor value for the test-drum speed for diagonal tyres, ETRTO proposes not to apply to E speed category symbol tyres the linear decrease of
the test-drum speed in function of the decrease of the speed category symbol by keeping, for safety reasons, the same test-drum speed as for F speed category symbol tyres, i.e., 32 km/h).
6. In the case of additional service descriptions mentioned in paragraph 6.2.5.1., it is proposed not to perform the additional load/speed test because the load-capacity approximates with a negligeable difference the reduction or the increase in percentage of the nominal load/speed combination applicable to the nominal speed category symbol (see Annex 8).
7. Type approval applications for radial tyres with load capacity index greater or equal to 122 and without the additional marking “LT”, or “C” have been done in the past for the speed category symbol N for which the load/speed endurance test procedure is not described in Annex 7, Appendix 1. To type approve such tyres the test speed was separately defined by the different involved Type Approval Authorities. In order to harmonize the test procedure to be used for the type approval of such tyres, it is proposed to amend the Annex 7, Appendix 1 by introducing testing conditions in line with the rule applied for defining the test speed of radial tyres with load capacity index greater or equal to 122 (i.e. starting from 32 km/h set for F speed category symbol, the test speed is increased by 8 km/h respect to the one set for the previous speed category symbol).
8. The definition of “snow tyre” is amended to clarify that “snow tyres” are not only suitable for the use in snow conditions but also on mud and by replacing the term “maintain vehicle motion” (i.e. keeping the vehicle speed and direction of movement constant) by a more general concept of “controlling vehicle motion” (i.e. also being able to change the vehicle speed and direction of movement as intended).
9. It is proposed to explicitly allow other technical measurement solutions of the tyre overall width by removing the words “by caliper” which fix a technical limitation. The removal of this technical limitation would be advisable following the principle of not stopping the technical innovations.
10. Editorial corrections are introduced to ensure that the terms “load-capacity” and “speed category symbol” are used consistently throughout the text and to remove some typing mistakes present in the current text.
