So, I tested my fitment today. I had my o.e. wheels narrowed to 9" wide. I then bought the cheapest used 275/55R20 tire I could find local to me. I didn't want to spend $1,100+ on tires that don't fit. Well, it fits. Definitely very close to touching at full lock, but close doesn't count. So, I went ahead and ordered the Blizzacks. I'll post more pix once I have all 4 of those on.
