I have used a pair back in 2003, the Michelin X-trem I think it's now called judging by the size and tread pattern. It is an enduro mtb tire. One of the best tires I've ever used, great cornering, surprising low rolling resistance and light weight. But the rubber on the side walls started cracking fairly early on, which looks very thin as you can easily see the casing weave. I haven't used any since because of that and being pricey where I'm from.
