225/45R17 will fit the wheel better.
I ran 215/45R17 PS4S on my current set of 17x8.
You can see there is a bit of stretch and look narrow for the wheel. Not dangerous or anything. The main thing I did not like is that I had to be extremely careful laying the wheels down flat or they would scrap as the tire didn't cushion/touch first.
