40,000 miles over 6 years of very ordinary city/highway driving on a light-weight car, driven conservatively by an mpg-conscious driver. Occasionally rotated. Picked up a nail once, had the hole plugged, no further problems. Very reliable, stable, fairly quiet and smooth. Not great in ice and snow, but drivable. Getting good efficiency, keeping them pumped up. Much much better than the OEM tires were. Still plenty of tread left. Very happy with this purchase; we'll see if anyone comes out with something compelling enough to make me switch in a couple more years when these are worn out, assuming these tires are even still made in 2015.
