At 5800 miles I have 5 mm tread remaining on the rear and a bit proud of 4 mm on the front. Considering that I typically wear through a set of sport touring tires in 6k miles (I had one set go 8k when I slabbed round trip to the east coast), this is very cool. The only other dual sport tire I have had were the oem set, which could have gone longer, so no direct experience. But most folk say 4 k miles from TKC 80's. Because of the upcoming Whitehorse/AK trip these tires will come off prematurely as well, and I won't get a full mileage report. However, I am now confident of doing the entire YT/AK trip on a single new set. That means a lot.
