Your tire manufacturer puts recommended tire pressure on the tire itself and I would start with that pressure for your base and then if you don't like the ride or traction lower it a bit. If you run them too low they will run hotter and of course wear the outside rims vs across the tread. I used to run 17s on a SPF years ago and I believe it was much higher than you are currently running. I'm current running Goodyear 15 inch Billboards and those are much different but still running 26 in the front and 23 in the rear.
