Sailun S637+
EU tyre label for every size: 12 sizes of this 3PMSF-marked tyre compared with the rest of the market
The Sailun S637+ is a 3PMSF-marked tyre for trucks and buses. Its supplier has registered it in the EU product database (EPREL) in 12 sizes (45 registrations including load and speed variants), for 14″ to 22.5″ rims.
Wet grip is rated B–C depending on size, fuel efficiency C–D and external rolling noise 71–73 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 9.5R17.5 16PR (Wet grip B · Fuel efficiency D · 73 dB), the weakest 255/70 R22.5 16PR (Wet grip C · Fuel efficiency D · 73 dB).
On the EU market since January 2010; the earliest production week registered is 44/2011.
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 (12 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. Weakest point: rolling noise, where most same-size rivals do as well or better.
All 12 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).
