There are several considerations in setting tire pressure:

1. Heating due to sidewall flex under load.
2. Ride quality.
3. Handling
4. Wear

If you know your axle weights, the Tire and Rim Association Year Book will give you the lowest pressure you can run and be ok with respect to sidewall flex/heating. I had a copy of it saved somewhere, but now I can't find it. Ride quality generally improves with lower pressure and gets worse with increasing pressure. Handling is usually bad with low pressure, gets better with increasing pressure up to a point, and then stops improving or even worsens as you continue to increase pressure. Wear can be uneven with too much or too little pressure. With some experimentation, you can find the tire pressures that work best for you.
