I hate running mismatched tires and I'm not exactly recommending it but you are going from PS2 to PSS not PS2 to say RE-11. I think the difference against running all the same tires will be there but it will be less substantial than running another tire brand that is 100% different in compound and tread. If you can bare with it you should be ok.. I'm running PSS in the front right now and AD08's in the rear. My front AD08's wore off so I bought a whole set of PSS because of the $70 kickback and I am hating the way the car feels right now. On the other hand I can sell the rear AD08's rather than waiting for them to scrub off but I will get next to nothing for them.. the dilemma
