so with the leveling kit and full tread you had no rub??Yea they rubbed if you cocked the wheels all the way, but they rubbed the plastic of the inside of the bumper so no harm done. Be careful though, because if they rub against the body of the truck at the corner, you will have some torn up tires. Best bet would be to get the level kit, and have no worries. Without a level kit though, I would say stick with 33s.
