I've been running the Shinko 804 / 805 setup since about June. I haven't had any problems - and I've been on / off road fairly regularly. On pavement the handling is good. No issues at all. On dirt, pretty much the same. I ride graded dirt, ATV trails, rocky and nasty crap, some minor water crossings, a little mud, etc. Still no problems. As for longevity, I can't really comment. They've got about 3,000 or so miles on them so far, and they're still looking good. I'm expecting probably 5,000 to 7,000 from this set by the way they're currently looking.
People should not be afraid of their governments. Governments should be afraid of their people.
