Somehow my wife is getting phenomenal economy in her Fit. I think it's mostly because she doesn't drive over 55, but her tank averages have consistently been above 45mpg this summer. She has 185/60R15 (?) Michelin Defenders she runs around 42-45 PSI, slightly oversized and a little narrower than stock. She also failed inspection recently because she doesn't brake enough during normal driving to knock the rust off - an easy fix.
