Going nuts with this and ready to kill some wheel and tire shops. I have a 04 F-350, psd with a 2" lift in the front. The wheel shops are telling me I cant go bigger then 17" rims witch I'm find with. But there telling me that the 265/75/16 or 17 is as big as I can go tire wize. So what size tire and rims will work with out the way the truck sits now?
