Amendments to the draft new regulation for the approval to tires installed on a vehicle in order to avoid overlap with UN R64 on spare tires.

Proposal to clarify the inflated run-flat tyres are within the scope of this regulation while uninflated run-flat tyres fall exclusively under UN R64 and to remove references to UN R64 since this regulation and UN R64 exist as independent parallel tyre regulations. The proposal seeks to improve the wording, including to align more closely with EU Regulation (458/2011).
