Syron Premium 4 Seasons
EU tyre label for every size: 8 sizes of this all-season tyre compared with the rest of the market
The Syron Premium 4 Seasons is a all-season tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 8 sizes (8 registrations including load and speed variants), for 18″ to 20″ rims.
Wet grip is rated B in every size, fuel efficiency C–D and external rolling noise 72–73 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 245/45 ZR18 (Wet grip B · Fuel efficiency C · 72 dB), the weakest 255/35 ZR19 (Wet grip B · Fuel efficiency D · 73 dB).
On the EU market since January 2020; the earliest production week registered is 03/2020.
How it compares in its sizes
We compared each size with all other all-season tyres of the same size and class in EPREL (8 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 (245/45ZR18)
Example: the 245/45ZR18 size, compared with the 78 other all-season 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
72 dB against a median of 71 dB in this size (1 dB louder).
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 8 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).
