What the label means on the road (225/65 R17)
Example: the 225/65 R17 size, compared with the 699 other summer tyres registered in this size.
Wet braking from 80 km/h
≈47 m with class D, against ≈41 m for the most common class in this size (C).
Fuel efficiency
Class D vs the typical C: ≈0.18 L/100 km more, about 28 litres more over 15,000 km for a 1,500 kg car.
Rolling noise
72 dB against a median of 71 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 11 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).
