The diameter of the wheel doesn't effect anything, just a shorter sidewall for the same size tire when comparing 17" vs 15"
With a 275 tire I ran 5.5" backspacing with a 8" wheel. Some lighter hammering on the inner wheel well was needed. You can run a 9" wheel with the same back space but more hammering is needed to the outer wheel house. If you pop the trunk and look at the wheel tub compared to the quarter panel you'll see the area that needs the hammering. You can use a a block of wood and jack to stretch this area, at your own risk of course, it can be hazardous.
There are a few gages/tools out now that simulate the tire you plan to run mounted, so you can play with backspacing and the width of the wheel.
