Proposal to ensure that that P-type tyres can be distinguished from non-P-type tyres.

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.

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.

Proposal for editorial improvements, including to update a cross-reference in paragraph 3.4. to read “3.1.2” pursuant to the earlier division of paragraph 3.1 into separate paragraphs 3.1.1. and 3.1.2.
