| Tyre abrasion: Proposal to replace document GRBP/2025/27 |
| Reference Number: GRBP-83-32/Rev.1 |
|
Proposal to supersede document GRBP/2025/27 for a new UN Regulation on uniform provisions concerning the approval of tyres with regard to abrasion performance. The regulation establishes scope, definitions, application requirements, marking standards, approval procedures, and technical requirements for class C1 tyres. It excludes temporary-use spare tyres, competition tyres, ice grip tyres, studded tyres, and certain other tyre categories. Type approval is granted if candidate tyres meet abrasion performance limits measured by one of two methods: vehicle testing on public open roads or indoor drum testing. Abrasion index limits are defined for normal, snow, and special use tyres, with adjustments for specific tyre groups. Requirements include conformity of production verification, penalties for non-conformity, and transitional provisions establishing Stage 1 and Stage 2 implementation timelines with specified dates for mandatory approval. |

| Tyre abrasion: Proposal to amend GRBP-83-32/Rev.1 |
| Reference Number: GRBP-83-49 |
|
Proposal to amend GRBP-83-32-Rev.1 to ensure robust tyre abrasion measurements regardless of test method used. Amendments modify paragraph 6.1 to require test facilities demonstrate equivalence per Annex 4 procedure; insert paragraphs 12.8 and 12.9 deeming inter-facility campaign participants equivalent for C1 tyres and allowing pre-regulation test data through 1 July 2028; insert Annex 3 paragraph 1.4 requiring inter-facility equivalence assessment; amend Annex 3 paragraph 2.8 with abrasion calculation equations including transfer function coefficient; insert test report items 1.1–1.4 in Appendices 2 and 6; and insert new Annex 4 establishing equivalence demonstration procedure for vehicle and indoor drum test facilities. |

| Tyre abrasion: Proposal to amend GRBP-83-32/Rev.1 |
| Reference Number: GRBP-83-53 |
|
Proposal to amend document GRBP-83-32-Rev.1. Paragraph 1.2.9. amended to exclude special use Professional off-road tyres from scope. Paragraph 2.51. amended to read that the authority which has granted type approval may verify conformity control methods, with normal minimum frequency of verifications at least once every three years. Justification states special use tyres should be excluded as no limits will be established for them, and the three-year frequency aligns with Schedule 1 of the 1958 Agreement. |
