Is it the wheels, tires, or combination of both?

I just swapped out my OEM lobster forks w/ Pirelli Rossos (4400 miles of gentle use) with a set of XRR/Carrera Sport wheels with Michelin PS2s (300 miles of prior use).

While doing some spirited driving on some winding roads, some with very sharp hairpins, I felt more yaw movement or what seemed like squirming with the XRR/Michelin combo. With the lobsters/Pirelli combo, I would usually feel a little front chattering or understeer, then the car would hook up. I would also sometimes feel the rear get a little bit loose, but not much noticeable yaw motion.

Has anyone else experienced this? Sorry if I'm not explaining this clearly - I don't track my car and don't have much to compare this to.

Thanks in advance for the responses.
