I have BFG AT LT285/75R16 on my LX450. Original tread depth for this tire is 17/32". I drove them over 35.000 miles on dirt roads. Now the tread depth is between 7/32" and 8/32" depending on tire. Which is between 41% and 47% of tread left. What is the minimum usable tread depth for this model of tire?
