I don't think tire diameter will be your issue.

JK, I use sissy tires too.

I usually use 235/45/17s on the rear for silly drifting activities. I'd like to think I feel the difference when I can use 235/40/17s. Not so much when I use 225/45 though.

For grip driving, I'd be willing to sacrifice a bit of acceleration in return for better braking and more speed through the turns. At the same time, It's already been mentioned that 245/40/17 is pretty close to stock rolling diameter. No reason to use tires meant for early 80s Hondas.
