I did an experiment with gas mileage related to tire pressure.
I found that the recommended tire pressure gave me on average 49mpg
Increasing by two pounds per tire put me over 50 mpg and four pounds gave me
over 52 mpg.
At what tire pressure are you compromising safety for mileage?

As my 2005 Prius has yet to be delivered to me, I don't have accurate
information as to the manufacturer's suggested tire pressures. But I do
know this: Never pump up your tires to a pressure higher than the maximum
pressure molded on the sidewall of the tire. Always check your tire
pressure when the tire is cold.

With 42/40 front/rear I have no handling problems.

I have had my Prius for almost 3 weeks. The average MPG is usually indicated
to be between 50 and 52 MPG, but I find this is just a bit optimistic. I put
in 20.8 gallons for the first 1028 miles of driving, for a real 49.4 MPG.
I get much better mileage when I avoid high speed highways, but most of my
usual commute to work is highway driving, and the above 70mph portion
has been increasing.
I have not yet touched the tire pressure. I guess I'd best check it.
