Update for those that are interested.
I got these tires put on at 213,626 miles on my tacoma. The truck now has 236,194 miles on it. So that means I have put 22,568 miles on these tires so far. According to Bfg's website, these come new with 15/32" of tread on them. Mine are now down to a hair under 10/32" of tread on them. So that means in 22,568 miles they are at 67% tread (rounded). I have only rotated these tires twice, so who knows if that has hurt the wear of them at all.
I have been extremely happy with them and will most likely buy them again when my truck needs another set of tires.
