I am thinking about dropping down to 17" wheels to save on weight (40+ lbs of unsprung rotational mass!), and to have a higher profile tire = a little softer ride. But I'm not sure what size tire on 17" wheels equals the stock ride outter tire diameter?? This is so my speedometer is still accurate.

225/45-17 would be good. You can go with other sizes if you want a wider tire or whatever by adjusting. Just look at the speed comparison to figure out what you're comfortable with.
 
Yeah, I'm thinking about Motegi Traklites 17x8". I have a black 2015 Sedan. I'll post pics soon.

Tire Rack specs gives revs/mile for a lot of their comparisons - just look at brand you have now and compare it to same brand with rim diameter you want - anything within 1 or 2 % (about what different brands vary in the same tire size) should be fine.
