I have 6 BFG TKO tires that are coming off my dually so I can put on a bigger set. Two of these tires have close to 70% of the tread left, 3 have about 30-40% tread left and one is best used as a tire swing. These are still on my truck and have never had a patch or been flat. I have a new set waiting for me at the tire dealer so these will be removed from my truck sometime this week.
