Slip angle mainly focuses on the front "directional" tires. On an aggressive turn under power the car basically turns in yaw meaning the back tires try to follow the front without the benefit of being able to change their direction. While there is also slip angle on the edge of the rear tire's contact patch the lateral load builds much quicker than the front, again the tires are fixed direction, the slip area grows until the contact patch of the tire is to small and it lets go. I am just saying that with t/a tires this happens much more quickly because of the hard rubber composite. And yes they will make noise warning you of impending danger but they will make lots more noise before they finally break loose. So also quite deceiving.

When the contact patch is broken by irregularities in the road on a hard turn there is no warning. The sound you hear is not a warning, but the tires screaming it's too late! Much more prone to happen on hard rubber tires.

You may wonder where I get all of this since I don't have track time. Well, I have been reading books that explain what I was experiencing when I was younger. Still a novice though!
