Roadstone N'fera SU1
EU tyre label for every size: 80 sizes of this summer tyre compared with the rest of the market
The Roadstone N'fera SU1 is a summer tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 80 sizes (93 registrations including load and speed variants), for 16″ to 22″ rims.
Wet grip is rated A–C depending on size, fuel efficiency B–D and external rolling noise 67–72 dB.
The label depends on the size. Sorted by wet grip, then fuel efficiency, then noise, the best-labelled size on sale is 275/40 ZR19 (Wet grip A · Fuel efficiency B · 70 dB), the weakest 225/45 ZR17 (Wet grip C · Fuel efficiency D · 70 dB).
On the EU market since September 2012; the earliest production week registered is 30/2012.
How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (80 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.
What the label means on the road (205/55R16)
Example: the 205/55R16 size, compared with the 1,042 other summer tyres registered in this size.
Wet braking from 80 km/h
≈41 m with class C, against ≈37 m for the most common class in this size (B).
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 80 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).

Same label values, different brand
These tyres have exactly the same label values as the Roadstone N'fera SU1 in most of the sizes they share, and both are registered in EPREL by the same manufacturer. Identical labels do not prove two tyres are the same: classes are broad. But consistent matches across many sizes point to a shared production family.
