Q1What changed7 changes
Fitting on vehicles in use of tyres approved to the 02 or 03 series (para. 12.17.)
New paragraph 12.17. covers new tyres manufactured before the date in paragraph 12.5. and approved to the 02 or 03 series of amendments. Until 6 January 2029, Contracting Parties applying this Regulation must continue to allow fitting of these tyres on a vehicle in use. Before this supplement, the Regulation had no paragraph 12.17.
Annex 2, Appendices 2 and 3: footnotes about UN Regulation No. 54 tyres deleted
Footnote 1 of Annex 2, Appendix 2 and footnote 2 of Annex 2, Appendix 3 are deleted. Each footnote was about approvals in accordance with UN Regulation No. 117 for tyres within the scope of UN Regulation No. 54. It said that these approvals “currently do not include the requirement on adhesion of tyres in worn state on wet surfaces”.
Q2Why it changed
- Proposed by
- Experts from the European Commission; experts from the European Tyre and Rim Technical Organization
- Working party
- GRBP, 77th session (February 2023)
Reasons
Tyres may remain in the distribution channels up to 30 months before they are fitted on the vehicles of the final consumers. Tyre manufacturers do not control the entry into service date. The authorities can only check the date of production of the tyres. Approval markings are affixed during the production process and cannot be changed later.

“Distribution channels of tyres are very complex and include several stages, involving numerous actors.”
“where they may remain up to 30 months prior to being fitted on the vehicles of the final consumers.”
“The entry into service date is out of the control of tyre manufacturers and the authorities can only verify the date of production of the tyres.”
“approval markings are affixed during the production process and cannot be changed subsequently.”
The existing transitional provisions did not address tyres produced to the applicable requirements and placed in the distribution channels before 7 July 2026. Scrapping them on 7 July 2026 would harm sustainability, with significant negative impact on environment, economic burden for the tyre industry and potential tyre shortages. The new transitional provision aims to allow these tyres to be sold and fitted on vehicles in use for an additional period.

“The existing transitional provisions do not address the issue of tyres produced in accordance with the applicable requirements and placed in the distribution channels before 7 July 2026.”
“If those tyres are to be scrapped on 7 July 2026, this will adversely affect sustainability, resulting in significant negative impact on environment, economic burden for the tyre industry and potential tyre shortages for the consumers.”
“will be allowed to be sold and fitted on vehicles in use for additional period not exceeding 30 months from 7 July 2026.”
The transitional provision is proposed based on clause R.4 of part C, “Transitional provisions for replacement parts for vehicles in use”, of the General Guidelines.
