And they do that with the best top speed..."
There's just fundamentally different approach to using tyres for the RB chassis and the adaption to these 18 inch rims. Tgat team really nailed it in basic understanding of what was needed for this element alone, makes me wonder if all the others have paid that much attention to this area.
Looking at comparison, the RB appears to use much less camber throughout it's suspension travel than the others (I've pointed that out before in comparison to SF23) and presenting the tread flatter to track surfaces under more of it's operating sphere, against what is usually considered "conventional" thinking for this aspect.
Watching some on board of them as they spin the rear tyres to leave from pitstop, you can see all of the tread area often start to scrub the whole way across (evident in Singapore coverage) as opposed to inner shoulders on most.
Verstappen approach of driving "softly" will likely make best use of this type geometry too. But still, base level understanding of what the tyres really need though is core to this design, and it seems far ahead of most, irrespective of aerodynamic superiority.
Slow to warm though
with some, ahem, unintentional consequences 
Those much heavier GT cars, with narrower tyres, should not be cornering at F1 speeds even on the corners in which downforce is far less relevant
