This Annex describes the certification provisions for tyre with regard to its rolling resistance coefficient. For the calculation of the vehicle rolling resistance to be used as the simulation tool input, the applicable tyre rolling resistance coefficient Cr for each tyre supplied to the original equipment manufacturers and the related tyre test load FZTYRE shall be declared by the applicant for pneumatic tyre approval.
For the purposes of this Annex, in addition to the definitions contained in UN/ECE Regulation No. 54 and in UN/ECE Regulation No.117, the following definitions shall apply:
‘Rolling resistance coefficient Cr’ means a ratio of the rolling resistance to the load on the tyre
‘The load on the tyre FZTYRE’ means a load applied to the tyre during the rolling resistance test.
‘Type of tyre’ means a range of tyres which do not differ in such characteristics as:
Manufacturer's name;
Brand name or trade mark
Tyre class (in accordance with Regulation (EC) No 661/2009)
Tyre-size designation;
Tyre structure (diagonal (bias-ply), radial);
Category of use (normal tyre, snow tyre, special use tyre) as defined in UN/ECE Regulation No.117;
Speed category (categories);
Load-capacity index (indices);
Trade description/commercial name;
Declared tyre rolling resistance coefficient
The tyre rolling resistance coefficient shall be the value measured and aligned in accordance with Regulation (EC) No 1222/2009, Annex I part A, expressed in N/kN and rounded to the first decimal place, according to ISO 80000-1 Appendix B, section B.3, rule B (example 1).
The tyre manufacturer shall test either in a laboratory of Technical Services as defined in Article 41 of Directive 2007/46/EC which carry out in its own facility the test referred to in paragraph 3.2, or in its own facilities in the case:
of the presence and responsibility of a representative of a Technical Service designated by an approval authority, or
the tyre manufacturer is designated as a technical service of Category A in accordance with Directive 2007/46/EC Art.41.
