Yes, and I'm sorry I forgot to mention it.
Lower pressures generate more flex and more friction in the tire. That lowers your mileage (fuel and tire) and makes heat - heat that can damage or kill a tire (and passengers - remember the Ford/Firestone fiasco).
Higher pressures are the opposite of above. Higher pressures tend to make a harder ride, but better on road handling.
I tend to run 15% above the calculated numbers as a safety factor. But, never exceed the max ratings on the tire sidewall.
