Thanks. I've been testing the effects of 17" wheels/tires on mpg since I bought my first Prius in 2005. There is ALWAYS a negative hit associated with upsizing. My question on the aero effects of such a change or that of decreased offset was an effort to try and figure out all of the variables that go into this fuel economy loss so we can try to reduce it.
