Report on discussions concerning the feasibility of a new UN Regulation on uniform provisions for the approval of pre-cured tread materials used for producing retreaded tyres or the approval of retreaded tyres produced by using mould cure process with regard to their snow performance.

Proposal for a reference document concerning a general approach for how to handle measurement uncertainties under UN Regulations within the purview of GRBP.

Proposal from the ad hoc working group on retreaded tyres to move provisions for snow grip performance of retreaded tyres and their classification as traction tyres from UN R108 and R109 into a new UN Regulation on type approval of retreaded tyres of classes C1, C2 and C3 with respect to their snow grip performance and/or classification as traction tyre.
