At 30,000 miles I have worn out my 285-65-20 BFG T/A KO with Mountain/Snowflake symbol and will be purchasing another set. I mention the Mountain/Snowflake symbol as BFG has at least two different tred compounds, winter being the softer compound. I understand the hard compound last 45,000 +. I wish I would have gotten more mileage out of $1550 tires, with replacements at $1600. The tires are right next to bald and what surprises me is they still ride and drive great. I questioned running them through the winter but did it anyway and I had no problems. I have had tires in the past that I felt had 15,000 miles left in them and had to take them off as I could not keep the vehicle on the road.
