I brought my X3 in today, and was told that I need new tires. The car came with the Pirelli Scorpion's and I have been pleased with them. I'm also intrigued with Tirerack's PZero Nero M&S Pinna tires. However, they don't have any reviews on the tire. Does anyone have a preference for either tire? I live in Chicago, so the tire would have to put up with the seasonal changes, which the Scorpion has done quite well with. The only reason I am put off my the PZero's are the seemigly too good to be true price of 80 bucks a tire, and the lack of reviews.

Thanks for the quick help.
