What the label means on the road (225/45ZR17)
Example: the 225/45ZR17 size, compared with the 532 other summer tyres registered in this size.
Wet braking from 80 km/h
≈34 m with class A, 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
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 33 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).
