I have a 2002 F-150 2wd x-cab I'm putting a 3½" Spindle System from fabtech, or I might put 3 Inch Lift Kits from procomp I would like to know what size tire to put uderneath the truck.(sizes with and with out a 2 in. leveling kit.)

 

You can clear 33x12.50's with a 3 or 3.5 inch lift. You may squeeze 35x12.50's on it with 5 or 5.5 inches of lift.
