So far I've ridden these a few hundred miles on anything from intermediate mountain bike trails to gravel to city streets and they've performed great on everything. They're nice and durable on rocks and roots, grip dirt corners well, and roll easy on asphalt or gravel. Got them on sale for a great deal too. My only complaint is that the tread is rather lop-sided or somewhat off-center at some points on one of the tires I got, but I was able to remedy that pretty well by inflating it with more air to set/align it better and it stayed good even when lowering the psi back down to normal.
These tires wear well - I have 1500 miles on them in the last 3-4 months. 85% street riding, but a good bit of gravelsingle-trackhardpackmud. They climb great until the ground gets too soft, and suffer in bad mud, but it's a gravel tire not a mountain tire. Low rolling resistance on the road, and great cornering and traction on the trail. I really like these tires.... except.
I have had more flats in my rear tire than I have had in any other tubeless tire I've mounted on this bike, and the Stan's sealant just doesn't seem to seal them. Just blows that sealant out through the hole, and I need to unmount it, use a sticker-patch on the inside of the tire, and re-seat. They seat just fine with C02, but takes me 2 canisters just to repair - one to locate the hole, and one to re-seat after I've patched it.
These are 5 star tires with 3 star puncture resistance.
