Duratrac max tire size 2.5 level

[Zebrahead]

Looking to purchase a set of Duratrac's on 18's. I have read so many good reviews about how they handle in snow.  I am trying to find the max tire size and the correct offset without any rubbing or trimming involved. Running ko2 265/70r18 now.  I was thinking 285/65r18 or 275/70r18.  I would really like 295/65r18 but i am sure thats not possible.  Anybody that has this setup or any advice would be greatly appreciated.
