I drove a friend's AP1 with no glass window, blizzak's, slammed and it went fine through a big snow storm last year even without T/C. Actually was fun and easy to drive, more so than my AP1 with 10-20% tread left in the summer. h: Only thing done to prep for winter mode was to take off the front lip, as it just plows through snow. Wouldn't say it's the best DD but it works. :fawk:
