I've witnessed several occasions of tire roll under with the PS2's at the track.
The tire seems to be camber sensitive for some reason.

Sidewalls giving away so that you are partially riding on them and tread on a hard turn-in.
Lack of camber adjust plus heavy front end is a big part of it...as we cannot adjust that part. I've seen this only on the PS2's and in each case they were b5's. With the problem being there, pressure was adjusted upward, say +5 psi and it did not go away and seemed like it became worse the higher the pressure. So with a few well-seasoned heads together it was said that camber is the culprit here...a design shortfall for the PS2 tire and the S4 front suspension and not a defect. I have never had the problem with my Conti oe tires so it is brand specific. Heavier rear sway bar may help too and again his event only occurrs when pushing hard into corners and is not a defect in the tire or the suspension.
