I will still do some additionnal research on internet but will likely try 245/40/17 RE71-R on 17x7.5 wheels this year. To me it looks like the most optimal setup for F-Street unless I find evidences that 225 would be better on 7.5 wide wheels.

Have you tried 245 tires?
how was it? Any issues?
I am think about going 223~235 on 17" rims all around for auto X.
It looks like there is only 0.1" thread width difference between 225 and 235 for most tires, but there is big jump from 235 to 245 in thread width.
If there is no issue with 245, I may try it. Otherwise, I will go with 225.
