Tire size questions? What fits

[BurlyMan]

So iv got an 07 f250 powerstroke with the camper package, and im told that package includes snow plow springs and about 1 to 1.5 inch of lift. The question is will i be able to fit 305/65/18 (33.7/12/18). I want to run 18x9 KMC XD bronze hoss w/ 4.5 inch backspacing. I need help I dont want to have to buy 285/65/18 there to small. A leveling kit will not help since the truck already sits level. I cant lift the truck bc I have to get into parking garages for work. HELP

you should be able to get the 305's to fit without much problem at all, a friend of mine has 35"s and just a level kit and no problems, so with your claimed 1.5" of lift from the plow spings, you should be fine.
