I would have to agree with the dealer for using a minimum tire pressure to prevent uneven or premature tire wear, you do what you want but if you'd like the best wear and performance from your tires, do what the dealer says. Tires these days aren't cheap so most of us like to get the most wear possible out of them, but I'm sure some will want to argue that. Can you run 25lbs of air in your tires...sure but will you get good wear and performance from them, probably not but again its your money. I doubt any of those charts are concerned with tire wear.
