Get your car at the height you want, then figure out tire, not the other way around. Honestly, the cars are more fun on a 225 or a 235 tops - you get wider and sure, there's more grip, but for something you drive every day it's overkill.
A 235/40/17 is a great fit on a 17x8 and can be done without too much work a WRX wagon (slightly more fender room than my car)
I can "fit" 245 rcomps on my wagon, but they don't *fit*
