Session 73 | Geneva | 26-29 Jan 2021
5. (a) UN Regulation No. 30 (Tyres for passenger cars and their trailers)

GRBP will consider a proposal submitted by the expert from the European Tyre and Rim Technical Organization (ETRTO) to amend provisions related to the extended mobility tyre (EMT) symbol.

GRBP/2021/4 | UN R30: Proposal for a new Supplement to the 02 series of amendments Proposal to amend the extended mobility tyre (EMT) symbol following the detection of dimensional inconsistencies within the International Organization for Standardization Working Group (ISO) TC31/SC3/WG19, where the dimension "0,33h" was judged wrong and constituting an unnecessary over constraint and to amend the inflation value to be used for the tyre conditioning when assessing the "flat tyre running mode" of "run flat tyres" and of "extended mobility tyres".

GRBP may wish to resume consideration of the new definition for “radial tyre” that was proposed by the expert from France at the previous session.

GRBP-73-20/Rev.1 | UN R30: New radial tyre structure definition proposal

GRBP may wish to revert to the roadmap for implementing Amendment No. 2 to UN GTR No. 16 (Tyres) that was presented by ETRTO at the previous session.

GRBP/2021/4 | UN R30: Proposal for a new Supplement to the 02 series of amendments Proposal to amend the extended mobility tyre (EMT) symbol following the detection of dimensional inconsistencies within the International Organization for Standardization Working Group (ISO) TC31/SC3/WG19, where the dimension "0,33h" was judged wrong and constituting an unnecessary over constraint and to amend the inflation value to be used for the tyre conditioning when assessing the "flat tyre running mode" of "run flat tyres" and of "extended mobility tyres".
GRBP/2020/21 | UN R30: Proposal for a Supplement to the 02 series of amendments Proposal to expand and improve the current definition of a radial structure while ensuring the radial tyres key features (mechanical decoupling between the tread and the bead).
