The label depends on the size. Sorted by wet grip, then fuel efficiency, then noise, the best-labelled size on sale is 265/60 R18 (Wet grip C · Fuel efficiency B · 73 dB), the weakest 225/55 R17 (Wet grip C · Fuel efficiency D · 72 dB).

How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (17 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Strongest point: fuel efficiency. Weakest point: rolling noise, where most same-size rivals do as well or better.
What the label means on the road (215/65R16)
Example: the 215/65R16 size, compared with the 860 other summer tyres registered in this size.
Wet braking from 80 km/h
≈41 m with wet grip class C, the most common class in this size.
Fuel efficiency
Class D vs the typical C: ≈0.18 L/100 km more, about 28 litres more over 15,000 km for a 1,500 kg car.
Rolling noise
72 dB against a median of 71 dB in this size (1 dB louder).
Estimates from the class ranges in Regulation (EU) 2020/740. A label class is a range, so a real tyre can sit anywhere inside it. Every 3 dB doubles the sound energy.
All 17 sizes
The small figure under each class is the share of same-size, same-season tyres this size matches or beats (“–” when fewer than five tyres share the size).
