Road tire for wide rim

Thought I’d throw this in just to clarify my fears. Top of second page, tire blowing off 42mm rim.

I keep thinking that I got this figured out, then I read another post like in that thread. Ideally, I’d just get the Marathon Supreme or BA 2.0, but don’t want to be blowing off tires.

Also this thread, pg. 9 post 126 Klaas Bill.
