Car breaks out with winter tires

Moin, So here’s the thing: yesterday I put on new winter tires from Goodyear. This morning I almost fell off the chair how much the car is now “floating”. It’s a Chrylser Stratus, i.e. I’m used to it all going a little more navigable, but I haven’t experienced that yet. Up to 70kmh everything is still normal, from 70 onwards I make the difference very clear and from 120 onwards you have to concentrate when driving. I don’t want to drive more than 140 anymore. I actually drive quite well. Zackig and now garnix goes more. Running direction is right and pressure is everywhere on about 2,4. I don’t really know what it can be about. As I said the difference is ENORM, lane change is only slow and no longer halfway fast because the car simply “slides away”. Is that still in any way normal? Greet you, tixiam
