18. The expert of ETRTO pointed out the need for a new definition of “traction tyres”, because the current definition did not well segregate real traction tyres from non-traction ones (GRBP-70-19). The experts from OICA commented on the document. The Chair invited ETRTO, in cooperation with OICA, to prepare a formal proposal for consideration at the next session. |
