I've been running a Commander II on the rear of two ST1100s for about 150k miles and routinely get 18-22k miles out of one, but I usually pull them off with at least 1-2k left. I decided to try the Commander III when it came out last year. I just pulled it off and it got 25k out of it, but it was worn down to the cords in one spot. That certainly wasn't planned, but I was riding back from Colorado and noticed it about 100 miles from home, so took it easy the rest of the way. I cut through the worn spot to see how much tire was left and was surprised to find about 1/4" left and there were 3 layers of cord in there...
I'm going back to a Commander II since the III was OOS. FWIW, I run 42 psi and use 2 oz. of beads in the rear tire. I run a rear BT45 on the front and get 23-29k miles per tire, with 1 oz. of beads. My riding is about 40% commuting and 60% touring.
