So why do they use the same AMD inner and outer wheel houses then? Duster has wider lip on the wheel opening on the quarter, but that doesn't make a lick of difference for clearing the tire if it's inside the wheel house.

AJ/FormS's Barracuda measures within a 1/4" of my Duster inner to outer wheel house, that's factory tolerances. the 17x7s have a 4 inch back spacing. I am going to sell the other pair of 17x7s & buy a pair of 17x9.5s 8 3/4 with big bolt pattern axles. Ill move the springs & or move the inner wheel tubs. Ill move the tubs fully 3inch or what ever I need. Have no idea on tire sizes for the front or rear. I don't want to run a low profile tire if I don't have to. The 17x9.5s I want to run on the back have a 5.05 back spacing.
What is the backspace on the 17x7's? What are you running in the back for a rear axle? 8 3/4 with BBP axles? Stock spring locations? Makes a pretty big difference.
In the front with a 17x7" a 215/50/17 would be your best bet, it's 25.5" tall. About the widest you'll be able to do is a 225/45/17, but that will still depend on the backspacing and that's only a 25" tall tire. Maybe a 225/50/17, but with the Barracuda front wheel opening you have to modify the lower front corner of the fender when you get close to 26" tall on the tire. 235/45/17's are supposed to be mounted on 7.5" wide rims or better.
What are your plans for the car? What tires do you want to run?
