I have the PS2's on the front and Super sports on the back of my Srt. I am very happy with both. Ive had no issue with uneven wear like that with stock alignments but recently went to max camber, still no issue. If your looking to save a few bucks im going to sell my 225/40/18 michelin PS2's for a wider front, shoot me a pm if your intrested

PS, was the car wrecked at all? I would get a lifetime alignment from Firestone and just get it checked every 6 months or so, mine was $150 but ive already had 3 alignments on me car in 6 months, the guys at the local shop are great here
