is 235/45/R18 too big for 2018 Sport Hatchback?

Just wondering if going up to a 45 aspect ratio on the stock rims is going to create any issues? I've been using wheel-size.com, and it says that there shouldn't be any problems...but i just thought I'd check here as well. I'm looking at winter tires, and scouring kijiji/craigslist to save some dough. There's a good set of 235/45/R18 X-Ice's out there, hence the question.

Did you every find out if they fit? Thinking about the same setup
