Small group (France, Netherlands, ETRTO, BIPAVER) proposal to restructure retreaded tyre requirements and regulations.

31. The expert from the small group on retreaded tyres reported on their activities (GRBP-78-29) and briefly introduced the solution envisaged by the group:

• Adoption of a new UN Regulation for type approval of retreaded tyres with regard to their snow performance without changing the technical requirements compared to the current text of UN Regulation No. 109 (GRBP-78-31), and
• Adoption of a new 01 series of amendment to UN Regulation No. 109 without the snow performance, with the aim to clarify the administrative requirements after a certain period with adequate transitional provisions (GRBP-78-30).

32. GRBP invited all experts to study both options and to provide their feedback to the small group on retreaded tyres, with a view to preparing for the next session a working document which would contain a draft new UN Regulation and amendments to both UN Regulations Nos. 108 and 109.
