Tires disengage from rim in curve, HELP incl. video

Goodyear Eagle F1 Asymmetric 2 ca. 3 Bar Front Wheels 225/40/ZR18 @ Goodyear Eagle F1 Asymmetric ca. 2,8 Bar The front tires are about half of the wear, the rear wheels are completely new, but another model (successful model). I had the feeling that in the curves the tires are detached from the rim and just push themselves under the rim at side load, then the DSC has regulated. The problem still exists, so today a video was made. You can see clearly how the tyre pushes under the rim or even hears it, about after 35 seconds. The tyres have no running direction and at the front it can be that the wheels were mounted the other way around, i.e. side replacement. But I changed them already before the crossbar conversion and now still the problem. What is the problem? Different wear of the front – and rear tyres? Different model and thus different profile? Side-verse mounting of the front wheels? Watch best in HD!http://www.youtube.com/watch?v=ksagYIZoSlk Ask for your advice!
