New wheels 3.0RB?

[Kody.B]

I know it's not doing anything particularly new, but I'm looking at putting Rota Gravels on my '05.
They're a 5x100 18 x 8.5 wheel, +44 offset.

Thanks to a stickied thread I've been able to determine the fitment will work, but I was wondering about the width. Does it scrub (inside of guards) and do you need guard rolling? I'm not 100% sure on how much width you can go.
I'd probably go with a 225/40/18 tyre if I can get the right width.

Thanks to anyone who can help.

A wider 235 will scrub. 225 from most brands wont.
