I had 'ill consequence', as you say, from trying this. In fact, though, I was quite lucky. I put new tires on an old school rim (80's Araya). The tire said 120 psi, so that's where I went. It rode fine, but just after I got off the bike...tick tick, BOOM! The tire blew off the rim. I confided in the C+V forum, and they told me to hold it down to 75 or 80 psi max., which has been fine ever since, in my case. This is not an iron-clad guarantee of success, obviously. I suggest you ask the C+V guys about your specific rim. They know all. Good luck.
