China proposal for an effort to harmonize GTR 16 with China tyre regulations.

Proposal to amend the GTR on tyres to incorporate China national tyre requirements.

Proposal for additional tyre specifications to

1. add values specified in FMVSS 119, clause S6.2 table II
2. add small rim diameter sizes that will not meet the larger sizes of the GTR

Action item 4 : ETRTO will make a proposal on the relationship between the test pressure used in each GTR test and the test pressures stamped on the sidewall as per 3.3.5 and 2.56.

Action item 5 : It seems that the markings are mandatory in Tyre GTR. ETRTO will investigate if the markings in paragraph 3 are mandatory according to the GTR text and will assess the need for rewording of paragraphs 3.2 and 3.3.

Action item 6 : ETRTO will provide the justification to change in R54 (and in GTR) the definition of the measuring rim, considering the prerogatives of the IWG to change or not existing text from R54.
