| Summary | Proposal to introduce provisions to allow type approval of special use tyres that fulfil the requirements for snow performance as laid out in Annex 7, to improve precision of the test procedures for measuring the wet adhesion of tyres in a worn state by using a moulded SRTT16 reference tyre (instead of a buffed tyre), to introduce new transitional provisions related to this change, to extend corrections already made to the 02 series to the 03 series and make additional editorial corrections, and to define the range for tyre inflation vis-à-vis rim size to reduce uncertainties in measuring tread depth. The proposal introduces the tyre reference F3611-22 per document GRBP/2023/2 submitted to the January 2023 session of GRBP. | ||||||||
