Proposal to permit the “LT” marking as a prefix or suffix to align the requirements with the current practice for C2 tyres with metric size designation. The proposed text for a prefix is in line with the latest draft of the gtr on tyres. The proposed text for a suffix is necessary for tyres designed to Japan Automobile Tyre Manufacturers Association (JATMA) standards. The proposal would add new tyres for light commercial vehicles (high flotation tyres) in Annex 5 of UN Regulation No. 54.
