TF TA will address the tyres abrasion performance by determining a standardized measurement method which will allow for the quantification of the microplastic emissions in the environment. At the same time, the TF TA will investigate the correlation between abrasion rate and durability and consider the inclusion of both abrasion rate and durability

Proposal to expand alignment of UN R152 with UN R131-02 series, in particular to clarify that the Technical Service may test in any conditions within those specified by the performance requirement section of the regulation, with any other speeds within the prescribed speed range. In addition, the Technical Service may verify that the control strategy is not unreasonably changed or AEBS switched off in other conditions than those specified in the performance requirement section and the report of this verification shall be appended to the test report.

Proposal to revise the limits for rolling resistance and wet grip, address tyres for vintage vehicles, and revise the definition for special-use C1 tyres.

Proposal based on the 07 series of amendments to remove elements which covered by UN R154 (WLTP), to include references to the draft UN Regulation on Real Driving Emissions (RDE), and to update In-Service Conformity (ISC) requirements for the purposes of establishing regional type approval equivalence. The proposal is incomplete. The EC expects to provide missing elements before the 87th GRPE session in January 2023. This document is available with mark-ups in pdf version and in docx format.

The existing transitional provisions do not address tyres produced in accordance with the applicable requirements and placed in distribution channels before 7 July 2026. Therefore, a new transitional provision is proposed based on the clause R.4 of part C – “Transitional provisions for replacement parts for vehicles in use” of the General Guidelines for United Nations Regulatory Procedures and Transitional Provisions in UN Regulations. It will clarify that new tyres manufactured before 7 July 2026 and approved according to the 02 or 03 series of amendment will be allowed to be sold and fitted on vehicles in use for additional period not exceeding 30 months from 7 July 2026.

Proposal to transpose the amendment 1 to UN GTR13, Phase 2 (GTR13-PH2). This proposal contains numbers of improvements to the original GTR to promote technical harmonisation and to achieve enhanced reproducibility and reproducibility of the test requirements, higher clarity and consistency, adaptation to technical progress,
