I would tend to agree with you.

Then again, tire pressure calculators are subjective and vary.

If I use the Silca one, my recommended pressure is around 75PSI. If I use the Giant one (Tire Pressure | Giant Bicycles), it's 65PSI. Giant has a ''hookless specific'' tire pressure calculator and factors in the inner rim width, while the Silca doesn't.

Who's right, who's wrong? I'm sure some of you will say that Giant's pressure calculator is full of crap and only meant to help sell their products. At 170lbs, I used their hookless wheels for several seasons inflated at 65PSI on 28mm tubeless tires and never had any issues. Roads are in bad condition overall where I live and I hit tons of potholes. They felt as firm as my current setup (hooked rims & 28mm tubeless tires) inflated at 75PSI.
