^ This one doesn't get driven in the winter. I completely agree with your ideas, but the roof is down about 95% of the time it's being driven!

This year's only mod-
195/65R15 Prius tires on the back.
Lowers the RPM another 50 @ 50 MPH vs. The 185/65's that were on it before.
Probably good for another 4 or 5 MPG, right?
