Wouldn't you be better off with a chalk test to see what a good psi for 'your' tires is, rather than comparing to other people with different tire brands, different tire sizes, different load rates, different models, different overall vehicle weights, different preferences, etc, etc ?

Chalk test is the best way for sure. I run my 40's at 28-29 psi.
