20x12? dang thats kinda wide??? I would think even 305's would be too small..
im on 285's on my 10" wide rims..305's would be too small. I have a 10" wide rim and 305's are about the smallest for them
Didnt think you were lifting it, but 325's would look better LOLwell I dont want my truck to be on some skinny little tires when I lift it..
