THE EUROPEAN TYRE AND RIM TECHNICAL ORGANISATION An ad-hoc UN Regulation specific for AT tyres would be nothing else than a photocopy of UN Regulation No. 75 with the some few additional paragraphs and the content of Annexes 5, 6, 7 and 8 replaced by the additions proposed in the document ECE/TRANS/WP29/GRRF/2013/20 An ad-hoc UN Regulation specific for AT tyres would require up to three years before publication.
