What does the common practice of going to a smaller tire size do to the overall gas mileage? I'm considering going to the original stock size tires for comfort (I don't race and may possibly increase my commute from 30 miles to over 100 mileas a day, round trip) and was wondering if I'll get noticeably better or worse mileage. If worse, I certainly won't bother.

Wait. Now if you're driving on the surface streets, every time you accelerate you're going to use that much more power to get it going. And I=MR^2, so the bigger the smaller the radius, the smaller the moment of Inertia gets. So bigger wheels will be better on the highway, but worse on the streets... unless of course you accelerate slower on the surface streets with smaller tires.
