4.2.2.1. Tyre rolling resistance
              Tyre rolling resistances shall be measured according to Annex 6 to the 02 series of amendments to UN Regulation No. 117, or an internationally-accepted equivalent. The rolling resistance coefficients shall be aligned according to the respective regional procedures (e.g. EU 1235/2011), and categorised according to the rolling resistance classes in Table A4/2.
Table A4/2
Energy efficiency classes according to rolling resistance coefficients (RRC) for C1, C2 and C3 tyres and the RRC values to be used for those energy efficiency classes in the interpolation, kg/tonne
