Studded tyres: Proposal for a new UN Regulation

Proposal for a new UN Regulation on the approval of approval of studded tyres with regard to their snow performance (distinguished from studdable tyres regulated by UN Regulation No. 117). GAR Note: Japan abstained during the WP.29 vote, noting that studded tyres are prohibited under their national legislation and therefore that Japan does not intend to apply this new Regulation.
