Semi-long-term update:
On my original (almost bald) Ecopias I was getting about 5.1 mi/kWh on the dashboard average (which I reset only every couple of months). When I replaced those with new Ecopia+, that dropped to 4.7, then recovered at least a couple of tenths after they wore in. I kept them at 44 PSI
Early last winter, I replaced those with Conti PureContact EcoPlus, which are now showing 4.5 on the latest reset, running at 47 PSI. It seems fair to say that those cost a little over 10% in range, but they are a bit better for traction on wet pavement (which I can't quantify, but I notice less wheelspin), so I am willing to take the range hit for now.
The new Ecopias are stacked under my deck and may go back on when the Contis wear out. I'll probably have barely 10 bars or just dropped to 9 bars then (currently mid-way through bar 11, I think: SOH is averaging 82.5 of late), if the Contis live up to their treadwear rating..
