Proposal to update certain Standard Reference Test Tyre (SRTT) denominations, to remove the distinction between the two Class C3 tyres, to clarify the text and remove the reference to tyres “not marked with speed symbol”. This document will be handled by GRB during its 68th session and is referenced under GRVA due to the “conversion” of GRRF.

Proposal to introduce a definition for “Extended Mobility Tyre” based on a new “minimum requirement” performance test procedure with the relevant pictogram to be used to properly distinguish such tyres. This document will be handled by GRB during its 68th session and is referenced under GRVA due to the “conversion” of GRRF.

Proposal to amend UN R64 in line with the introduction of the “extended mobility tyre” into UN R30 (see document GRVA/2018/6). This document will be handled by GRB during its 68th session and is referenced under GRVA due to the “conversion” of GRRF.

Proposal to

1. modify the scope with regard to Category S and R agricultural vehicles,
2. modify the paragraph numbering (and related footnotes) to improve text clarity,
3. to correct an error in Annex 5 Table 7 where “35×16” should read “36×16”,
4. amend Annex 7 Part E to address variations of load-carrying capacity for tyres for construction applications (industrial tractors or skid-steers / mini-loaders) with speed category symbol “D”.
