| Reference Number: GRBP/2023/5 |
|
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. |
