well, you CAN fit tires on a wide spectrum of rim sizes.. like i had a friend who ran 12.5" wide tires on a 6" rim...
but from the manufacturers, it's different for every tire. for BFG, they recommend a 8"+ rim for 315/75R16...which is sorta like a 35x12.5 tire...getting them to fit the truck is another story.
