Or you can switch it up a bit by crossing the magical anti wheel-bending >4" of sidewall and likely fit some 235/45R19s without any fender liner rubbing or stock suspension interference. Speedo will be a bit more off, but nothing to post about on the fora.

Sorry for seeing this late.
235/50-18 will likely NOT clear the upper suspension mount on OEM offset tires, unless that particular brand/model of tires runs narrow compared to the stated specs. They could probably fit with like +20 offset wheel.
Here's a pic of a 235/50-18 horizontal view, with tires being about 2/32nds worn from new. Full tread tires will likely rub.
It's basically level with the suspension arm. Not every 235/50-18 tire is the same and one might get a lucky draw. These were effectively on a +11 offset wheel and there was probably a 10-15mm clearance to the suspension arm horizontally. So, a +20 wheel would probably make this borderline clear.
225/50-18 should fit though.
Sorry, I don’t know much about this. That seems to work for sidewall interest and still giving good width?
