I'm come'n up short everywhere. The best tire i could find is a Nokian Hakkapeliitta 285/60/R18. It's got an amazing tread design.
My roommate has got the winter version (275 front/ 315 rear) tires to the summer 20s on her 4.8is and she has no problem with winter driving anywhere. I wish these vehicles were more modular for all kinds of applications.
