I have them in the 31x10.5R15 flavor and like them alot!
Granted, they're not mud grips which I'm coming from but they do decent in general trail running around. I think they get excellent wet road traction. I lived in Houston,TX for 3 months and got to do a lot of wet road driving. They stop well in the rain.
I also got a chance to do some snow/ice driving with them when I lived in KS last year. They did much better than my BFG Muds on snowy roads (duh). I had traction problems, but hey I'm from Texas and I have a 2WD! Seriously though, I always got where I wanted to go in town.
I've got about 45K on my Pathfinders and they're starting to get a little thin. I would suspect they have ~10/32nd tread left with regular rotations.
Here's a pic of them on my '99
