How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (21 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 (265/60 R18)
Example: the 265/60 R18 size, compared with the 507 other summer tyres registered in this size.
Wet braking from 80 km/h
≈37 m with class B, against ≈41 m for the most common class in this size (C).
Fuel efficiency
Class C, the most common class in this size: no difference to the typical tyre.
Rolling noise
73 dB against a median of 72 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 21 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).
