UN R75: Proposal for Supplement 19 | WP.29/2021/6
Document Title: UN R75: Proposal for Supplement 19
|
Document Reference Number: WP.29/2021/6
|
Description: Proposal to - Change the definition of the tyre size designation by including prefixes and suffixes as well as the code for the tyre structure
- Clarify the use of sizes listed in Annex 5
- Move the definition of “reinforced” into a paragraph that is not subordinated to the definition of “Structure of a tyre”
- Correct references and typographical errors
- Rearrange paragraphs and amendments in order to increase readability
- Delete an unnecessary cross-reference to UN Regulation No. 54
- Change the definition of “bias-belted”
- Amend the definition of “snow tyres” by replacing “ordinary (road-type) tyres” (which is not defined) by “normal tyre”, removing the note that snow tyres generally have more widely spaced ribs or blocks
- Include a general provision addressing the gap between the effective date of entry into force and the date of notification of the adoption of the Supplement to the Contracting Parties
- Keep the restriction of measurement of overall diameter after load/speed test only to diagonal tyres (For radial the variation of outer diameter of the tyre, measured six hours after the load/speed performance test as specified in paragraph 2 of Annex 7, is far below ±3.5 per cent from the outer diameter as measured before the test.)
- Remove use of the word “moulding”
- Resolve conflicting provisions in Annex 2 concerning the minimum size of the approval mark
- Clarify that mounting motorcycle tyres on motorcycle rims is the standard configuration and that “M/C” marking is optional for the sizes listed in Annex 5.
