I was at a party a couple of weekends ago, and noticed a PriusII parked in the grass. Jimmy LaFave was leaning against it, holding his party-pooper dog on a leash. Now, I'd never met Jimmy, but I knew who he was because in these parts (central Texas) he's a celebrity.
Of course, I couldn't pass up the opportunity to accost a prone hybrid owner in order to pit my mileage against their own, no matter if his was celebrity mileage

I meekly walked over and asked how he liked his hybrid.
"Oh! We LOVE it!" he exclaimed.
After a bit of banter, he told me he'd recently replaced his tires, and regretted his decision not to buy the Toyota-recommended tires. Apparently, his mileage was suffering. I am assuming it was because he'd bought tires with a different diameter than the stock Prius, which whould totally FUBAR the Prius' OBD's mileage calculation.
At any rate, I told Jimmy and his wife about this site, so hopefully they've surfed by here and gained some mileage tips from you guys
