A couple of things - first, you can't "hand calculate" mileage properly unless the computer knows the right tire size. Doing it by GPS ain't gonna work because GPS is not nearly accurate enough.
Furthermore - everyone is talking about tire size but no one is considering what is almost certainly the bigger factor here - tire weight. What brand/model were the old tires and what brand/model are the new tires?
