How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (39 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 (205/55R16)
Example: the 205/55R16 size, compared with the 1,042 other summer tyres registered in this size.
Wet braking from 80 km/h
≈37 m with wet grip class B, the most common class in this size.
Fuel efficiency
Class C, the most common class in this size: no difference to the typical tyre.
Rolling noise
71 dB against a median of 71 dB in this size.
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 39 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).
