If you're carrying extra weight, it's a good idea to go 10 or 20 psi up from whatever is normal for you. And the recommended pressure is not necessarily the best for you. It depends on the width and weight, the tire, and other factors.
My Paselas are really old, I wouldn't dare.
Back in the day, one of my mountain biking buddies and I broke into algebra trying to express the relationship between tire pressure, rider weight, and all of those other factors. I'm okay with reading the labels and deviating depending on conditions.
