The label depends on the size. Sorted by wet grip, then fuel efficiency, then noise, the best-labelled size on sale is 275/70 R22.5 (Wet grip C · Fuel efficiency D · 71 dB), the weakest 245/70 R19.5 (Wet grip D · 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 (4 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.
All 4 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).
