Radar Dimax Winter Sport RFT
EU tyre label for every size: 23 sizes of this winter tyre compared with the rest of the market
The Radar Dimax Winter Sport RFT is a winter tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 23 sizes (23 registrations including load and speed variants), for 16″ to 20″ rims.
Wet grip is rated C in every size, fuel efficiency D and external rolling noise 72–73 dB. Every size carries the three-peak mountain snowflake (3PMSF), the mark for tyres tested in severe snow.
On the EU market since November 2016; the earliest production week registered is 48/2016.
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 (8 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Strongest point: fuel efficiency. Weakest point: rolling noise, where most same-size rivals do as well or better.
What the label means on the road (225/55RF17)
Example: the 225/55RF17 size, compared with the 12 other winter and 3PMSF 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
72 dB against a median of 71.5 dB in this size (0.5 dB louder).
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 23 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).
