Well, first fill today with the new tires.

I got 24.4, which is well above my typical commute tank of high 23's.

Despite the rr observation above, I made one important driving change. There are two or three hills that I had been downshifting from 4th to 3rd to tackle (DWL style). Now I use a more open throttle position - although well above WOT - and climb them in 4th. No lugging at all.

I've also used 5th a bit more liberally, down to about 45 mph on flat ground.

It's just one fill, so I can't get overly excited, but it was nice to know that the tires did not adversely affect mpg. In fact, maybe I'm entirely wrong and they have lower rr.

Anyway, there's my update.
