Sorry If I come off as dense, Im just trying to make sure I'm on the same page, you are giving me a ton of great information.
Hypothetically, If I'm considering 255/45r17 on all four corners using those 17" Cragars that are 9 inches wide. They have 5 inches of backspacing. With only 5 inches of backspacing I probably won't have any clearance issues with tie rods ends that others have had since they had more backspacing. Of course If I were to go that route I should order one of the wheels to do a test fit before ordering the rest of the wheels and new tires because like you said it comes down to rim design and the design of the rim may or may not interfere with the tie rod ends. Also to check to make sure the rim will fit over the large disc brake center. Am I following you correctly?
here is a direct link to the 9 inch wide wheel they offer.
