yes I was thinking doing something like that after watching the video, I am not sure about using the hit event however as that is constantly triggered by ground contact. I am thinking getting the z velocity of the spring each frame and then increasing the damping value accordingly, as for the tire pressure it would be simply a constant value added to the damping, the guy in the video even told the tire itself is kinda like a spring and dampener so why not merge the too in our case. however this is all theory I didn’t put any of this to practice yet.
