What the label means on the road (225/50ZRF17)
Example: the 225/50ZRF17 size, compared with the 64 other summer tyres registered in this size.
Wet braking from 80 km/h
≈41 m with class C, against ≈37 m for the most common class in this size (B).
Fuel efficiency
Class C vs the typical D: ≈0.18 L/100 km less, about 28 litres less 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 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).
