Kumho --12,200 before the sips were down to cord on the left side.
Pirelli --16,400 almost to wear bars, now on 2nd Pirelli.
Part of the problem with the Kumho may have been a little too much air. I ran 32-34. On the Pirelli I use 28-29. Not sure but the extra air may have prevented the sidewalls from flexing and keeping more of the tread on the road.
