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 Checked 2026-09-25.
