I just switched out my 19" runflats for normal Michelin Latitude HPs. I was surprised that my ride on bumps is not significantly better. I live in FL with perfect roads so I was not exactly having road issues. The normal tires have taken the edge off the on center feel. It is now slightly mushy and not as laser sharp. I can't believe I am saying this, but I may switch back to run flats for my next set. The pricing is similar now although they won't last as long. The bottom line is the engineers tuned the suspension for runflats. I have Adaptive Drive so this may have made the switch more drastic for me.

No mater what, I always will have a spare and never drive on a run flat that is low.
