Hard chassis – normal?

On my Auris TS HSD FL 16″ rims, pressure is 2.5 bar. And I feel the chassis is very hard – without being sporty. Even on seemingly flat roads, the car is constantly in motion; every mouse hole is passed almost unfiltered. In addition, a slight swinging (especially loaded) with light ground waves. Is this normal with the car? The predecessor (Megane 3 Kombi) was similarly tight, but drove more precisely. But with a little over 102 TKM the chassis can be more precise. Not to be exhausted?!? Tires are also Dunlop (back Conti), but with the winter tires – Michelin Alpin 5 (? Hold the current model) – it was only minimally better. Although the car has to be inspected again soon, but if there is something wrong with the chassis, I preferred to use it to our free workshop. The friendly on site has me at self-confident prices…
