Bridgestone Potenza RE050A
EU tyre label for every size: 37 sizes of this summer tyre compared with the rest of the market
The Bridgestone Potenza RE050A is a summer tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 37 sizes (61 registrations including load and speed variants), for 15″ to 20″ rims.
Wet grip is rated A–C depending on size, fuel efficiency C–E and external rolling noise 69–75 dB.
The label depends on the size. Sorted by wet grip, then fuel efficiency, then noise, the best-labelled size on sale is 215/40 R17 (Wet grip A · Fuel efficiency C · 71 dB), the weakest 275/40 ZR18 (Wet grip C · Fuel efficiency E · 72 dB).
On the EU market since December 2008; the earliest production week registered is 49/2008.
How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (36 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Weakest point: fuel efficiency, where most same-size rivals do as well or better.
What the label means on the road (195/55 R16)
Example: the 195/55 R16 size, compared with the 726 other summer tyres registered in this size.
Wet braking from 80 km/h
≈41 m with class C, against ≈37 m for the most common class in this size (B).
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 37 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).
