hey guys i was wondering if i can fit 245/45/18 size tires on my Infiniti I35 with stock setup. The stock setup on this car is 215/55/17. My only concern is the tires rubbing when i turn the steering all the way around and when going over bumps. The main reason i wanna install this setup is because i m getting M35 rims and tires for practically a steal. 
any help will greatly be appreciated

you’ll be fine with that upsize… it’s only .37" taller.
