FWIW, the Ecopia 422+ tires got back all the miles I was hoping to in about 1000 miles, and at least part of that was probably just waiting for spring to thaw. I'd been getting 42-44 on the estimator in fall on the shoulder-worn Goodyears, bought the Ecopias in January, and by April the low 40s estimates were happening again. (Still have never seen higher than 45 at unplug, but I'm not exactly TRYING hard.)
