Typically, the Anakees run a touch over $200 for a pair, shipped.. I've always mounted my own.. Double A has a set on right now and his will see 9K pretty easily. I got 8k out of mine, but I'm hard on tires..
Although, I did do a weekend of trail riding in the UP with Anakees that were about 2/3 worn, and didn't have any problems in the wet, but it was wet sand..
My bike is currently wearing Kenda 270's.. They (my opinion) suck on the road. Very squishy in corners.. They squish and then settle, but it gets your attention when they squish.. My next set are Kenda 761's.. I think they'll be a great compromise, and they were $100 for the set..
