Roadstone N'blue 4Season
EU tyre label for every size: 16 sizes of this all-season tyre compared with the rest of the market
The Roadstone N'blue 4Season is a all-season tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 16 sizes (18 registrations including load and speed variants), for 14″ to 18″ rims.
Wet grip is rated B–C depending on size, fuel efficiency C–D and external rolling noise 68–72 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 195/65 R15 (Wet grip B · Fuel efficiency D · 68 dB), the weakest 215/60 R17 (Wet grip C · Fuel efficiency D · 72 dB).
On the EU market since July 2026; the earliest production week registered is 30/2016.
How it compares in its sizes
We compared each size with all other all-season tyres of the same size and class in EPREL (16 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: fuel efficiency, 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 234 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 D vs the typical C: ≈0.18 L/100 km more, about 28 litres more over 15,000 km for a 1,500 kg car.
Rolling noise
69 dB against a median of 71 dB in this size (2 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 16 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'blue 4Season 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.
