ETRTO report on the study on the Dimensional Requirements for tyres with radial or run flat structure after having performed the load speed endurance test. ETRTO proposes to amend the UN Regulations No 30, 54 [and 75] by removing the requirements for tyres with radial and run flat structure.

ETRTO proposal for the replacement of the current Standard Reference Test Tyre as it is being phased out as production will stop mid of 2020. Snow performance test in R117 currently requires SRTT14 as a reference tyre. SRTT14 needs to be replaced and test procedure amended.

Supporting information regarding the proposal for the type approval of special-use tyres designed for severe snow conditions.

Text submitted by chair of IWG ASEP for the status report

Text by IWG ASEP for revision of ASEP as a future concept of real driving

The text submitted by the Chairman of TF MU for the draft terms of reference

Changes to the proposal to align definitions across tyre regulations and align the regulations with technological progress, correct an editorial error, and clarify that the ply rating is not applicable to T-type temporary use tyres.

The text submitted by the experts from the European Tyre and Rim Technical Organisation (ETRTO) to amend the Japanese proposal for a Supplement to the 02 series of amendments (ECE/TRANS/WP.29/GRBP/2020/6)

Proposal to clarify that it is not necessary to require an ISO 10844 asphalt track surface in cases where the vehicle is at a standstill provided that the surface is dense and without substantial absorption characteristics.

Status report

Information from Chair on 2020 schedule of meetings of interest to GRBP experts

Text prepared by the experts of TF TPMSTI in order to align with the provisions of European Union Regulation 2019/2144 and to introduce the TPMS requirements for all vehicle categories

Proposal for alternative language regarding markings to avoid use of the term “moulded” which could be interpreted as a technical design restriction.

Proposal to expand and improve the current definition of a radial structure while ensuring the radial tyres key features (mechanical decoupling between the tread and the bead).

The text has been prepared by the experts of the Task Force on Tyre Pressure Monitoring System and Tyre Installation (TF TPMSTI) in order to align with the provisions of European Union Regulation 2019/2144 and to introduce the tyre installation requirements for all vehicle categories

Proposals prepared by the ASEP II informal working group to clarify UN R41 and introduce provisions to improve testing to be more representative of real-world operation by expanding the scope of tests.

Per the transitional provisions of Supplement 3 to the 04 series of amendments, from 20 January 2021, the specifications for the test site reproduced in Annex 4 will be replaced by the provisions of ISO 10844:2014. Therefore, this proposal aims to align the 04 series of amendments with ISO 10844:2014, replacing provisions from ISO 10844:1998 (and proposing a clearer image for Figure 1).

Proposal to require wheel attachments with three or more fixing components (nuts or studs) in the scope of the Regulation, to restrict the difference in pitch circle diameter (PCD) of a wheel type comprised of more than two versions, to carry out additional rotating bending tests on each version with a PCD difference to a tested version of more than 6.5 mm, and to establish specifications for comparison of replica wheels with the minimum level of the vehicle manufacturer´s replacement wheels.

Proposal prepared by the experts on communication interfaces of the Task Force on Tyre Pressure Monitoring System and Tyre Installation (TF TPMSTI) to update the requirements on the communication interfaces between towing and towed vehicles.

Proposal prepared by the Task Force on Studded Tyres (TF ST) to establish a new UN Regulation on uniform provisions concerning the approval of studded tyres with regard to their snow performance (distinguished from studdable tyres regulated by UN Regulation No. 117).

Proposal to amend the extended mobility tyre (EMT) symbol following the detection of dimensional inconsistencies within the International Organization for Standardization Working Group (ISO) TC31/SC3/WG19, where the dimension “0,33h” was judged wrong and constituting an unnecessary over constraint and to amend the inflation value to be used for the tyre conditioning when assessing the “flat tyre running mode” of “run flat tyres” and of “extended mobility tyres”.

Proposal to align the provisions for retreaded tyres with the proposals of the European Tyre and Rim Technical Organization (ETRTO) for UN Regulations Nos. 54 and 117.

Proposal to align the provisions for retreaded tyres with the proposals of France for UN Regulation No. 30 and of the European Tyre and Rim Technical Organization (ETRTO) for UN Regulation No. 117.

Proposal to require wheel attachments with three or more fixing components (nuts or studs) in the scope of the Regulation, to restrict the difference in pitch circle diameter (PCD) of a wheel type comprised of more than two versions, to carry out additional rotating bending tests on each version with a PCD difference to a tested version of more than 6.5 mm, and to establish specifications for comparison of replica wheels with the minimum level of the vehicle manufacturer´s replacement wheels.
