Love that you are trying to put some science to kart dynamics. The only situation I think would achieve the right side of your chart (twisting) would be "an inside front tyre in a kart setup with a combination of some or all of -- weight too rearward, rear track too wide, weight too low, front tire pressure too soft. Or maybe excessive helmet aero! lol
Full Noise Racing i'm a TAGr super and i think i deal with that side a lot. rear track is a bit of a funny thing to list as you can go wide to a point then start to lose grip, there are two different kinds of grip: what i like to call "mechanical" grip (the physical produced by the tire and setup) and "dynamic" grip ( the amount of grip generated by driving style and mechanical grip combined). you can set the kart up to get a lot of mechanical grip but if you lean on the tire (increases the weight acting on the tire) you will overheat the tire and (if basic understanding is correct) start to get excessive twist leading to understeer and/or bump oversteer (skidding from loss of adhesion with the rear tires). on the other hand while setting the kart up for little mechanical grip lets you lean on a tire more to generate the grip and potentially allow for a higher mid corner speed if you don't keep control on the amount of weight acting on the tires (to much or not enough) you will get push understeer (skidding) on corner entry and/or exit oversteer (not sure if this is skidding or twisting).
We run the Bridgestone YLC tire in most WKA classes in the USA. I have noticed that the tire for the first day of use rarely ever show graining on the tire. Its the 2nd and 3rd day that you start to get that graining, what cause this, is it the tire getting to many heat cycles and becoming harder?
NEED more videos like this! thank you!
Brilliant. Nice video man. You only one, who talk about fact, that all things work only in the middle, absolutely all
Love that the videos are now on TH-cam. Keep it up!

WOW! never tought about that. make sense

you could talk more about the correct pressure
