Those tyres have great chunks stuck to them after they've been through all the marbles making them much bigger hence why it's scraping on the floor?
Yes but the edge of the floor is obviously close enough to the tyre to scrape this debris onto the floor. The particle size of the gravel is unlikely to be greater that 20mm so the gap must be less.
There is also an obviose large gap in the picture between the floor edge and the lowest part of the tyre shown, so the ride height must be at maximum high default.
If you then look at any other side pictures of the car on track, you will see a much bigger gap between the edge of the floor and the tyre which proves the car has a very large range of potential ride height levels.
You can draw the curved triangle in 2D by lowering the car from the first picture.
This range is far to much for the car to achieve any where near a constant race long down force. The conclusion has to be that there is a system on the car that maintains a good ride height at all times the car is running and that it is either an active system or driver adjusted.
