Beats me, there was ice on the car this morning!!!! Friday was nice, almost 70 degrees. I had to EOC in order to keep the car from overheating!!! Great insentive!!
I have been working on new tires for the summer. I have a feeling that my autocross tires are not going to help my mileage, they weight a ton and are intentionally wide.
I found another government report (
http://onlinepubs.trb.org/onlinepubs/sr/sr286.pdf) that indicates General Ameri G4S was a decent roller and in my preferred FE size 175/70, plus they are $35 a tire. Dang.
