trail claw II tires

[ky 2stroker]

has anyone ever used the trail claw II tire before? Im wanting to get some but I cant find a place that sells them anywhere. Dennis kirk used to sell them, but they dont anymore.

for anyone that has used them, are they are pretty durable general purpose tire? I mostly trail ride and drag race and do some play riding out in the field, like barrel racing and stuff. how good do the knobs hold up before wearing down? it looks like these tires would bite pretty good in most stuff.
