Sorry, my bad. I have a limited coupe with 41K miles. I have no idea what the SRT-6 runs in the 1/4. As for the wear on my PS2s, I had them replaced at around 28K because, from a stop, they wouldn't hook up during moderate acceleration. I actually had the 2 driver side tires replaced again at around 31K miles because I hit a pot hole this winter that bubbled them and bent my front rim.
