RoadX AP866
EU tyre label for every size: 4 sizes of this 3PMSF-marked tyre compared with the rest of the market
The RoadX AP866 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 14″ to 22.5″ rims.
Wet grip is rated C in every size, fuel efficiency C–E and external rolling noise 72–74 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 13R22.5 18PR (Wet grip C · Fuel efficiency C · 72 dB), the weakest 7.50R16LT 14PR (Wet grip C · Fuel efficiency E · 72 dB).
On the EU market since February 2018; the earliest production week registered is 02/2020.

Strongest point: rolling noise. Weakest point: wet grip, where most same-size rivals do as well or better.
