Hankook ION Flexclimate SUV
EU tyre label for every size: 14 sizes of this all-season tyre compared with the rest of the market
The Hankook ION Flexclimate SUV is a all-season tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 14 sizes (16 registrations including load and speed variants), for 17″ to 21″ rims.
Wet grip is rated B in every size, fuel efficiency B–C and external rolling noise 70–71 dB. Every size carries the three-peak mountain snowflake (3PMSF), the mark for tyres tested in severe snow.
The label depends on the size. Sorted by wet grip, then fuel efficiency, then noise, the best-labelled size on sale is 235/60 R18 (Wet grip B · Fuel efficiency B · 70 dB), the weakest 255/40 ZR20 (Wet grip B · Fuel efficiency C · 71 dB).
On the EU market since January 2024; the earliest production week registered is 45/2023.
How it compares in its sizes
We compared each size with all other all-season tyres of the same size and class in EPREL (13 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Strongest point: wet grip.
What the label means on the road (235/60R18)
Example: the 235/60R18 size, compared with the 158 other all-season tyres registered in this size.
Wet braking from 80 km/h
≈37 m with wet grip class B, the most common class in this size.
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).
