UN R124: Proposal for amendments

Proposal to require wheel attachments with three or more fixing components (nuts or studs) in the scope of the Regulation, to restrict the difference in pitch circle diameter (PCD) of a wheel type comprised of more than two versions, to carry out additional rotating bending tests on each version with a PCD difference to a tested version of more than 6.5 mm, and to establish specifications for comparison of replica wheels with the minimum level of the vehicle manufacturer´s replacement wheels.
