I recently put a set of these on my rig ('02 Tacoma 4x4) and wanted to pass along a review of them.

I bought 'em at Town Fair Tire for $125 each installed for 265/60/16. I've got about 2000 miles on them so far with mixed driving on snow covered pavement, packed dirt roads, some mild mud and pavement. They're very quiet on the road. I noticed no issues in the rain. They do seem to lock up fairly easily on pavement though.
If you're looking for a nice aggressive AT tire similar to the BFG AT do yourself a favor and check these tires out. They're significantly cheaper than the BFGs.
