I have tried the different tire manufacturers discussed. On the rear, the Commander II is by far the best I've tried. I am on my 2nd MC II. The first had 16000 on it when I ran over a drywall screw. The tread had thousands left. I'm on my 2nd tire, and have a little over 10,000 miles on it. Tread is at least a half left.
I run a Dunlop Ellite 3 on the front. 1st tire had 15,000 at the change. Still had life left, but we were going on a trip. On the second front, and have ran 9,000 miles with about half left.
I tilt the scales at 285. My wife isn't telling, but I'd guess she's 150 lbs.
