How it compares in its sizes

Strongest point: fuel efficiency. Weakest point: wet grip, where most same-size rivals do as well or better.
What the label means on the road (195/65R15)

Rolling noise
71 dB against a median of 71 dB in this size.
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 27 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).
