Width and backspacing for 17 inch rims would be the same as for any other size of rim. If you have a 14 inch rim that fits properly then just order 17 inch rims with the same width and backspacing and your tires will be in the same location.
keep the same offset....
a typical RWD mopar offset is ~ 1/4" (6.35mm) positive offset (what a 15x7 cop wheel is with it's 4.25" back space. so a 17x7 with 4.25 will fit fine. a 17x8 with 4.75" backspace is the same, +6.35mm offset.
tires, keep the overall width/diameter about the same as what others are using (say, if they're using a 255/60R15, a 235/55R17 is the same height, ~7/16" narrower, or a 255/50R17 is the same width/height as the 255/60R15)...
if you want all the same size so you can rotate the tires, I'd go 17x7 or 17x8 with 235/55R17....lots of tire options in that size (OEM size for the mustang GT, and ford crown vic police interceptors)
