This is interesting, I looked up the max pressures in the Nomad brochure (Issue 30) for 1.75 width and found 61 psi front and 68 psi rear.
Those numbers looked different to me than my recollection, so I looked up the numbers in the Nomad brochure (issue 20) and there the 1.75 inch width is listed with a max pressure at 50 psi front and 58 psi rear.
Apparently these pressures have changed over time. I thought that they were absurdly low when first published, now more reasonable. I think I was running about 85 psi in my rear 1.50" width Marathon (plain version, with greenguard) on my Sherpa, Salsa Gordo rims when I did the Glacier Waterton loop.
These pressures are intended to prevent rim failures, not specific to brand and model of tire.
If you do the search yourself, do a word search for pressure, that finds it in the brochure quickly.
