Diamondback DR259
EU tyre label for every size: 17 sizes of this summer tyre compared with the rest of the market
The Diamondback DR259 is a summer tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 17 sizes (17 registrations including load and speed variants), for 16″ to 21″ rims.
Wet grip is rated C in every size, fuel efficiency C–D and external rolling noise 71–73 dB.
The label depends on the size. Sorted by wet grip, then fuel efficiency, then noise, the best-labelled size on sale is 215/65 R17 (Wet grip C · Fuel efficiency C · 71 dB), the weakest 225/55 R19 (Wet grip C · Fuel efficiency D · 71 dB).
On the EU market since October 2023; the earliest production week registered is 12/2021.
How it compares in its sizes
We compared each size with all other summer tyres of the same size and class in EPREL (17 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Weakest point: rolling noise, where most same-size rivals do as well or better.
What the label means on the road (215/65R16)
Example: the 215/65R16 size, compared with the 860 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 C, the most common class in this size: no difference to the typical tyre.
Rolling noise
72 dB against a median of 71 dB in this size (1 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 17 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).

Same label values, different brand
These tyres have exactly the same label values as the Diamondback DR259 in most of the sizes they share, and both are registered in EPREL by the same manufacturer. Identical labels do not prove two tyres are the same: classes are broad. But consistent matches across many sizes point to a shared production family.
