# Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Commission Regulation (EC) No 692/2008 (Text with EEA relevance), Division 4.2.2.1: Tyre rolling resistance


Tyre rolling resistances shall be measured in accordance with Annex 6 to UN/ECE Regulation No 117 – 02 series of amendments. The rolling resistance coefficients shall be aligned and categorised in accordance with the rolling resistance classes in Regulation (EC) No 1222/2009 (see Table A4/2).
Table A4/2
Energy efficiency classes in accordance with 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

RRC = 6,5
E
RRC = 9,8
RRC = 8,6

RRC = 8,5
G
RRC = 12,9
RRC = 11,2
Empty
If the interpolation method is applied to rolling resistance, for the purpose of the calculation in paragraph 3.2.3.2. of Sub-Annex 7, the actual rolling resistance values for the tyres fitted to the test vehicles L and H shall be used as input for the calculation procedure. For an individual vehicle within an interpolation family, the RRC value for the energy efficiency class of the tyres fitted shall be used.
In the case where individual vehicles may be supplied with a complete set of standard wheels and tyres and a complete set of snow tyres (marked with 3 Peaked Mountain and Snowflake – 3PMS) with or without wheels, the additional wheels/tyres shall not be considered as optional equipment.
