I'm mistaken, the G4 alloys are 5.5" width. I took these myself at my local Mitsubishi dealer.
The GTs are 4.5, like the steel wheels.

195/40R17 or 195/45R16. I didn't confirm if the circumference is the same for the speedometer, but it should be "close enough" (doesn't really matter anyways if I can adjust the diameter in ETACS). Online calculators suggest they will fit the wheel wells both in diameter and in depth. I'm not concerned about ride quality difference but I hope it's not as "wagon wheel" looking as some cars with massive wheels.
Are you sure? I mean I haven't looked at the wheel specifically but the GT does have a wider section tire than the other models (175/55R15).

I'm pretty sure all 15" Mirage wheels are this size...
A 15 x 4.5" wheel would be insane...even for Mitsubishi.

Well...let's split the difference and call it 39mm. Either way, an OEM 15x5" wheel has too much offset (whether it's 38 or 40) and sits too far under the fenders...in my opinion.
Go with a 15x6.5" aftermarket wheel with a 40mm offset for maximum visual impact and no rubbing issues.
I'm not aware of anyone that has successfully done this. I just remember someone posting that ETACS has a predefined set of circumference values you can choose from. For what it's worth, I run 185-55-15" tires that are 23" in diameter, and the speedometer error is so minor (2.5%) you can't tell it's off at all....I didn't confirm if the circumference is the same for the speedometer, but it should be "close enough" (doesn't really matter anyways if I can adjust the diameter in ETACS)

FYI, we are all wrong. the 2017 GT wheels are 15x5, +40mm Offset, just went out and looked at mine:

I apologize for my incorrect information. When I Google the various trim levels, 4.5" rims come up. I thought everything on line is true!
Apparently, there are variations in width. A 4.5" wide rim can easily handle a 145-175 width tire. 165-185 seem to be the most logical tire widths to run without modifications. A 5" wide rim +/- 0.5" is a good size for the Mirage. I don't find 4.5", 5", or 5.5" to be odd at all. Sadly, most aftermarket rims are 6"+, which is more rim than necessary for this small car.
