Okay so I might be picking up a set of 37" bfg km's tomorrow for my 1999 F250 super duty. It's in getting painted right now and cut out flares done. Wondering what the best kind of rims and offset would be. The tires are 37x12.50R17. Looking into either ion or worx rims but wanna know the best offset or whatever. Not that knowledgeable in this area so that is why I am curious. Hope I can get some help.
