Best MPG = ? PSI

How do you make a poll?

What is the ideal tire psi for best mpg?

16" ?

17" ?

18" ?

Ride comfort, handling and MPG are likely somewhat mutually exclusive to a point if one is trying to maximize all three.

If just trying to maximize MPG, then the highest pressure recommended for the tire will likely provide the least rolling resistance and the make/model of the tire may come into play as well.

I don't know if this matters, but my XJR wheels/tires are 35PSI.

I've been running mine @ 38psi. I wonder if I toyed with it if I could measure a difference. Maybe I'll go 42?
