Koryo K22
EU tyre label for every size: 30 sizes of this summer tyre compared with the rest of the market
The Koryo K22 is a summer tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 30 sizes (30 registrations including load and speed variants), for 16″ to 26″ rims.
Wet grip is rated B in every size, fuel efficiency C and external rolling noise 71–75 dB.
On the EU market since June 2016; the earliest production week registered is 45/2015.
How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (29 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. Weakest point: rolling noise, where most same-size rivals do as well or better.
What the label means on the road (235/60R18)
Example: the 235/60R18 size, compared with the 725 other summer tyres registered in this size.
Wet braking from 80 km/h
≈37 m with class B, against ≈41 m for the most common class in this size (C).
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 30 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).
