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.

Discussion of run-flat tyres and extended mobility tyres (EMT) in support of a general proposal to establish approval procedures for EMT under UN R30 and include EMT as “emergency mobility equipment” under UN R64. The proposal makes reference to recent activity on ISO 16992 regarding EMT test protocols.

Introductory statement to document GRRF-86-04 proposing amendments in order to provide a legal approval framework for extended mobility tyres under UN R30 and their recognition as “emergency mobility equipment” under UN R64.
