I am thinking about putting the tires from a 2011 F-350 onto my '08 EL. The tires are Michelin LTX 275/70r18. Does anyone run this size on their Expy? They are a little wider and taller, but not too much.

I am also thinking about installing a 1" leveling kit. The tires would need to fit whether I do the leveling kit or not. Anyone running leveling kits?
