Sunny NW631
EU tyre label for every size: 34 sizes of this 3PMSF-marked tyre compared with the rest of the market
The Sunny NW631 is a 3PMSF-marked tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 34 sizes (89 registrations including load and speed variants), for 13″ to 20″ rims.
Wet grip is rated D in every size, fuel efficiency B–D and external rolling noise 69–72 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 265/70 R16 (Wet grip D · Fuel efficiency B · 70 dB), the weakest 235/45 R18 (Wet grip D · Fuel efficiency D · 70 dB).
On the EU market since June 2019; the earliest production week registered is 20/2019.
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 (34 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Strongest point: rolling noise. Weakest point: wet grip, where most same-size rivals do as well or better.
What the label means on the road (205/55R16)
Example: the 205/55R16 size, compared with the 839 other winter and 3PMSF tyres registered in this size.
Wet braking from 80 km/h
≈47 m with class D, 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
69 dB against a median of 72 dB in this size (3 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 34 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).
