Well, success story, left late for work, so 60mph back road and 70mph on the highway. Pulled into work with an indication of 22.5mpg, which is about the same as my best with the old tires. On the trip home I did 60mph highway, and 45 back roads, pulled in the driveway with an indication of 27.2mpg
. At speed 45mph is 30-31mpg, so I think I did pretty good for what my mods are so far. Fill up in in 1-2 more work days.
