There is some truth to that!
However, I like to run lower pressure for more comfort and control (bigger contact patch), and a bigger tires allows us to run lower pressure. I am only 150 lbs without gear, and run 90lbs front and 95 lbs rear on my 23mm Mich Pro4s and have not had any problems with pinch flats yet, it would be nice to safely run even lower pressure.
