The stock tires for our cars are rated a little higher than the PSS. As others have mentioned our stock tires are like SUV tires and are rated accordingly Pete and others run different tires without a problem. Here are the specs of both tires.

besides the size difference in the side wall the PZERO's are rated to hold 220 lbs more than the PSS. That is why they won't sell you the tires since they do not meet the factory specs GM said these cars should have on them.
Input from others would be appreciated.......Maybe Pete can chime in and give you and me a little more info.

I really appreciate all the technical info. Maybe I'll get the Michelins put on the front!
