This is what I'm running in my signficantly heavier SPF (I'm 600lbs heavier). The lighter the car, the less air pressure needed, so IMHO, 30lbs in a Kirkham has got to be too much, however air pressure settings are rather "personal", and everyone has their own preferences.
Taking tire temps is the best way to judge inflation. I did this consistently when I ran GY Slicks on the track, and this led me to inflate them to 21F/19R. I took the tire temps after each 20 minute session. BTW, I believe that tire temps need to be taken after agressive/spirited driving, not just straight line.
Before I had a pyrometer, I used the "white shoe polish" method to see of the tires were rolling over onto the side wall. This process worked fine, however it's not as accurate as taking tire temps.
IMHO, I would not worry about wear. I drive my SPF so little (about 3k per year) that my old tires died of old age before they wore out.
YMMV,
