My car was a CPO and came with Michelin Primacy HP run flats. They are quiet and seem to water pretty good except the front tires that already had an out of alignment wear pattern established on the outer edges of both tires. If these were available in the 20" sizes (255/35/ & 295/30) I'd use them again, but they are not, so I'm going with the Michelin PIlot Super Sports. The only drawback is now i need a spare tire as they aren't runflats. I don't do canyon carving with my car so the stiff sidewall thing doesn't bother me. I like the convenience of if I do get a flat, I can at least get off the road via an exit without jacking up my rim.
