How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (23 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: fuel efficiency, where most same-size rivals do as well or better.
All 26 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).
