It looks like Thorn again has revised their maximum tire pressure ratings.
The Mega brochure (2016, May) on page 31 cites 2.25 width tire maximum at 50 psi. This pressure rating is dated May 2016.
The Mega Brochure (2015, June) on page 35 cites 2.25 width tire maximum at 55 psi. This pressure rating is dated July 2014 although published in a 2015 document, I did not check other documents.
I said they changed it "again" because they had different numbers than these in past Nomad brochures. The Winter 2013-2014 Nomad brochure (Issue 30) listed 49 psi front and 54 psi rear maximum pressures.
I only cited 2.25 width tires here because that is the size I usually use on my Nomad in summer.
Maximum pressures in some other sizes have changed too, the only tire sizes where the maximum pressures remained the same from 2015 to May 2016 are 700c 23mm and 25mm width.
