How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (106 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Strongest point: rolling noise. Weakest point: wet grip, where most same-size rivals do as well or better.
What the label means on the road (215/60 R17)
Example: the 215/60 R17 size, compared with the 761 other summer tyres registered in this size.
Wet braking from 80 km/h
≈41 m with class C, against ≈37 m for the most common class in this size (B).
Fuel efficiency
Class C, the most common class in this size: no difference to the typical tyre.
Rolling noise
68 dB against a median of 71 dB in this size (3 dB quieter).
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 108 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).
