I would say buy the best tires you can afford. They are you ONLY link/connection to the road. I think the Michelin PS2's are the way to go here. Why do you want the more expensive PSS ? Were are talking about spending, what $50 more per tire? How much did you pay for your car? $45K?
$788(Dunlaps) vs $1014 (Michelin PSS's) ?
Just to be clear... you are talking about going with
non run flats and in the
225/255 sizes, right?
Here are the results from a search I did on Tire Rack's website:
