Michelin Pilot XGT Z4 tires are only $124 from tirerack. How do they perform, or are they so cheap for a reason. They are ultra high performance all-season, 255/45/18.

 

I had them on my '96, and they were very good. I'm surprised at that price. I paid a lot more for them, but that was about 6 or 7 years ago. Anyway, my impression was that they held the road well, were very good in the wet even light snow, and were quiet.
