Picked up my rims today. They're Motegi Racing MR7's 7" +40 offset. Now I am looking at tires. [oh yes, ANOTHER tire question. Just what everyone needs

]
Now, I'm looking at two sizes. I've a gen3 v6 LE and as far as I know stock springs and struts for now. [I may when they need to be replaced drop it an inch, or there abouts] Now with that in mind, I'm looking at either a 215.R50.17, or the other option 225.R45.17
Now, what I'm curious is, since I really know very little about car tires, is how will these be different when driving, [excluding the obvious] How will each handle? will there be rubbing issues? or turning issues, more so with the 225's? Does one noticeable drive better or worse than the other when pretaining to size? Just would like some input before I make a decision what to get.
TIA
