Hankook Smart City AU04
EU tyre label for every size: 4 sizes of this 3PMSF-marked tyre compared with the rest of the market
The Hankook Smart City AU04 is a 3PMSF-marked tyre for trucks and buses. Its supplier has registered it in the EU product database (EPREL) in 4 sizes (10 registrations including load and speed variants), for 22.5″ rims.
Wet grip is rated B–C depending on size, fuel efficiency C–D and external rolling noise 67–71 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 305/70 R22.5 (Wet grip B · Fuel efficiency C · 67 dB), the weakest 275/80 R22.5 (Wet grip C · Fuel efficiency D · 71 dB).
On the EU market since May 2021; the earliest production week registered is 27/2020.

Strongest point: rolling noise.
All 4 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).
