All RFTs aren't created equal...I found my Pzeros to handle awesomely but on roads around here the car would literally go airborne over many surfaces inducing traction light to go bonkers (reminding me to turn it off)
It is however all relative to what you're used to. Switching out of those runflats to a dunlop sport maxx tts I gave up 10% turn in immediacy but gained 70% in ride quality.
