Get away from run rocks. You won't understand it till you do. The ride is do much better on regular tires.
The Michelin PSS are great tire and they have very low if any noise verses a Run Flat or a track tire. They wear better than Extreme Summer tires like the Dunlop DII's and are great in the rain. They handle a little less (very little) that other extreme tires but they are great all around. You will like them 1000 time better than any run flat tire.
Yup the PSS is not an All Season tire. It's a Summer only tire. http://www.tirerack.com/tires/tires.jsp?tireMake=Michelin&tireModel=Pilot+Super+Sport
