Document title UN R172: Proposal for Supplement 2
Date 28 Nov 2025

Proposal to reinsert requirements for the classification of tyres of class C1 that were erroneously omitted in the amendments to para. 6.4. introduced via Supplement 1 and to align the wording with UN R30, to correct a reference to “Appendix 1” that should read “Schedule 1”, and to delete the field for “Extension No.” in the Communication form since the extension is already integral to the Approval Number.
