i'd stick with 16's if your auto crossing
This would be my advice too. I have 48 offset 17x7" wheels with 215/45-17 Falken Azenis RT-615's and P1 springs. They rubbed on the rubber trim strip in the rear fenderwell, which I then removed, and they have never rubbed since. No fender rolling needed.To be safe I would suggest a 17x7 , 52-48mm offset with a 215-45-17 tire to avoid any issues . I have rolled rear fenders and run 17x7.5 48mm offset with a 225-45-17 tire .
