What the label means on the road (235/45ZR18)
Example: the 235/45ZR18 size, compared with the 468 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 B vs the typical C: ≈0.16 L/100 km less, about 25 litres less over 15,000 km for a 1,500 kg car.
Rolling noise
70 dB against a median of 71 dB in this size (1 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 14 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).
