Called BFG on tuesday and their stocking warehouses with the new 18" sizes in the All terrain KO's and will release Sept. 1st, So I know they exist. Want to put tires on this truck with the existing 2" AS level kit (wont dare refer to it as a lift) This truck has 5000 miles on her and i'm very happy with it like it is. So I am torn between the 305/65 18 At's (33.6 x 12) or the 35" MT's. Using stock rims and like the idea of having 35's on the truck but at only an inch less and with a more "streetable" tread I think maybe the AT's. I dont know I burn brain cells thinking about this crap. Both tires will fill the wheel wells nicely and give it a much more appropriate "tough" look but I cant help but think that any rub issues that might exist may be alleviated by a little bit smaller tire. A little help with your thoughts. BTW, running 5.4 3.73LS with Xcal2, exhaust, CAI etc. so I think power will be ok.

 

Unless you do a lot of offroading, you will be better off with the AT KO's. Like you said, the size is so close that really won't be an issue.
