Wow, the buckling of the tire wall in the last two pictures is crazy. I guess that happens because there is enough friction to stop the wheel moving, and the axle is trying to turn it faster, causing a shear force. With normal tires, I assume they would just slip at that point and spin because they don't have enough friction in the contact patch touching the road.

Yep! The tires are actually designed to do that. It really helps to prevent things from snapping by absorbing some of the shock when the cars drop the clutch or let go of the trans brake.
So the tires are acting like torsion springs then?
It increases the footprint of the tire at the start, giving the car more grip. Here is a video: https://youtu.be/-VF0JwxQqcA?t=10m42s
