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 (4 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.
All 4 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).
