Tyre fuel efficiency class
How much the tyre resists rolling, which is what it costs in fuel or battery range. A has the lowest rolling resistance.
- What it looks like on the label
- A fuel pump beside a tyre, over an A to E scale with the tyre’s class marked by a black arrow (top left of the tyre label).
- Printed on
- Tyre
- Unit
- letter A–E (RRC in N/kN)
- Regulation
- Regulation (EU) 2020/740, Annex II (content and format), Annex I (grading)
Where the regulations differ
This is the tyre’s A–E scale, not the appliance A–G energy scale. The thresholds are stricter for bigger tyre classes: C1 (cars), C2 (vans), C3 (trucks and buses).
What the regulation says
On a tyre label
- What the number measures
- Rolling resistance coefficient RRC: rolling resistance force per unit of load.
- Unit
- letter A–E (RRC in N/kN)
- Test condition
- measured under Annex 6 to UNECE Regulation No 117 and aligned with the laboratory alignment procedure of Annex V.
- Classes
- C1 tyres A: RRC ≤ 6.5 · B: 6.6–7.7 · C: 7.8–9.0 · D: 9.1–10.5 · E: ≥ 10.6 N/kN
Regulation (EU) 2020/740, Annex I, Part A (grading); Annex II, point 1.1 (label): The fuel efficiency class shall be determined and illustrated on the tyre label on the basis of the rolling resistance coefficient ( RRC in N/kN) according to the ‘A’ to ‘E’ scale
