The Sonar S780 is a summer tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 13 sizes (15 registrations including load and speed variants), for 12″ to 15″ rims.

The label depends on the size. Sorted by wet grip, then fuel efficiency, then noise, the best-labelled size on sale is 195/70 R14 (Wet grip C · Fuel efficiency C · 70 dB), the weakest 165/80 R15 (Wet grip C · Fuel efficiency D · 70 dB).

How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (13 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
What the label means on the road (175/70R14)
Example: the 175/70R14 size, compared with the 670 other summer tyres registered in this size.
Wet braking from 80 km/h
≈41 m with wet grip class C, the most common class in this size.
Fuel efficiency
Class D, the most common class in this size: no difference to the typical tyre.
Rolling noise
70 dB against a median of 70 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 13 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).
