  1. change measurement units for drum speed in Annex 7 from min-1 to km.h-1 to align the requirements with other tyre regulations;
  2. correct the wording from “speed category symbol” to “speed symbol” (as defined in para. 2.33);
  3. correct the wording from “load capacity index” to “load index” (as defined in para. 2.32);
  4. correct a reference to para. 3.2.13. of the Regulation in Annex 7, Appendix 1;
  5. correct a boundary value of load index in Annex 7, Appendix 1;
  6. delete in paragraph 2.1 in Annex 7, the possibility to use the 2.0 m drum diameter to perform the endurance test.

In Annex 10, the proposal aligns the text with Annex 7 of UN R117, 02 series of amendments, Supplement 5.
