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.
29. The expert from ETRTO presented GRRF-86-04, introducing GRRF-86-05, and announcing the intention of ETRTO to propose provisions for extended mobility tyres in UN Regulations Nos. 30 and 64, on the basis of initial work done by the tyre industry at the International Standardization Organization (ISO). GRRF noted the reference to ISO documentation and invited the expert from ETRTO to prepare a more detailed proposal for consideration at the next GRRF session, both concerning UN Regulations Nos. 30 and 64.
