I have Max. sidewall ( or maybe 1 or 2psi more ) air pressure in my FEH.
I get awesome MPG. Over EPA all seasons.

When my DAD borrowed it for a week, never have driven a Hybrid before in his life, he averaged 37 MPG in mostly city driving. He's not a hypermiler. So there's gotta be something to the air pressure helping.

Also, my tires have perfectly even wear at 37,000 miles. Looks like I will get 80,000 miles from them too!
