Michelin Pilot Alpin 5 K1
EU tyre label for every size: 2 sizes of this winter tyre compared with the rest of the market
The Michelin Pilot Alpin 5 K1 is a winter tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 2 sizes (2 registrations including load and speed variants), for 21″ rims.
Wet grip is rated B–C depending on size, fuel efficiency 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 255/35 R21 (Wet grip B · Fuel efficiency C · 71 dB), the weakest 305/35 R21 (Wet grip C · Fuel efficiency C · 70 dB).
On the EU market since March 2025; the earliest production week registered is 09/2025.
How it compares in its sizes
We compared each size with all other winter and 3PMSF tyres of the same size and class in EPREL (2 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Strongest point: fuel efficiency.

Rolling noise
71 dB against a median of 72 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 2 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).
