Base document for consideration during the 22nd IWVTA SG58 subgroup session.

In relation to action items 1 and 3 under the “Major Results and Action Items of the 21st SG58 meeting” (document SG58-22_01), OICA offers its views for consideration.

At the entry into force of Regulation No. 0, the secure Internet database for the “data exchange of type approvals” (DETA) under Schedule 5 of Revision 3 to the 1958 Agreement may not be fully operational. This proposal from the DETA informal group introduces footnotes to clarify that requirements in paragraphs 4.4., 5.2. and Annex 6 do not apply until the DETA system is complete.

Proposal from the DETA secretary to the IWVTA subgroup on UN R0.

1. Addition of new definitions (Section 2);
2. Harmonization of the Load Range concept in relationship to Inflation Pressure (Section 2),
3. Alignment of the provisions for tyre marking and physical dimensions of PC tyres with the most recent developments in UN Regulations Nos. 30 and 54 (Sections 3.3 and 3.5),
