What's keeping you from getting 225 (or 215) RE71R, A052, RT660, etc? That would make a bigger difference in grip and handling feel than 225 vs. 215 PS4S...
I really doubt there's a whole lot in it, either 225 or 215 will work on 7.5" wheel, personally I'd go 225 just based on 215s looking puny on 17x7.5"...

I've done some research and it seems that having 0.5 narrower tread width than the wheel width is good for feedback/responsive. The Ps4s in stock size have a 6.8 tread width so that is 0.7 narrower than the wheel width. Should I go with the 225 which is a 7.5 tread width or just stick with the 215 which is also the same diameter as stock. How much more grip will I really gain by moving up to 225 and is it worth it in exchange for the driver response and feedback of the 215? Im thinking also that the 225 with take more advantage of the -2 camber I have because more contact patch.
