| Tyre abrasion: Proposal to amend GRBP-83-32/Rev.1 |
| Reference Number: GRBP-83-53 |
|
Proposal to amend document GRBP-83-32-Rev.1. Paragraph 1.2.9. amended to exclude special use Professional off-road tyres from scope. Paragraph 2.51. amended to read that the authority which has granted type approval may verify conformity control methods, with normal minimum frequency of verifications at least once every three years. Justification states special use tyres should be excluded as no limits will be established for them, and the three-year frequency aligns with Schedule 1 of the 1958 Agreement. |

| Tyre abrasion: Comments on compromise proposal for Annex 4 |
| Reference Number: GRBP-83-52 |
|
ETRTO comments on EC/JRC compromise proposal for Annex 4 tyre abrasion. ETRTO proposes an ALI range minimum of 0.5 as feasible and consistent with statistical distribution in MA results, rejecting the 0.7 range as unrealistic. For Generic Transfer Function gain, ETRTO recommends retaining a = 1.38 rather than the revised a = 1.45, to minimize rejection of good vehicle test results. ETRTO requests TFTA ToR amendment to confirm these conditions by February 2027 based on TA-45-9. |

| UN R83: Proposal to amend the 09 series of amendments |
| Reference Number: GRPE-94-51 |

Proposal to delete two paragraphs relating to “Operating Mode Switch” that were overlooked when that concept was removed from Regulation No. 83, from both the manufacturer’s information document (Annex 1) and the approval certificate addendum (Annex 2). The same documentation requirements were removed from the 08 series of amendments (during GREP-93), differing only in paragraph numbering. |
