Help with wheel choice 15" or 17"

Barracuda I saw recently had those wheels on it. Seems I read they were 16s though. My memory sux. Anyway...
17 is far from stock. Leaves little space for tires' sidewall.
I'm frugal so I would keep same size on all 4 corners. Rotating the wheels and get my moneys worth out of those high dollar tires is a must for me.
