Why F1 Car Tires Look Like This?

[0:00]Why do Formula One tires look like this after a race? At first, it seems like normal wear and tear of cars pushing at insane speeds around the track. But the truth is very different. After crossing the finish line, every car goes through mandatory weighing, and if it's even a fraction under 798 kilograms, the driver is instantly disqualified, no matter if they finished first. Now, here's the catch. During the race, almost 100 kg vanish from the fuel tank, and the driver himself loses up to 3 kg from heat and dehydration. Even the tires get lighter as they grind against the asphalt. So right after the race, they secretly leave the racing line and drive over sections littered with rubber debris from other cars. The hot tires instantly collect these chunks, adding those few extra kilograms.
