Thanks NoData! The tire was new (my spare KO2). Probably had 1700 miles on it. Wasn’t overloaded. Unfortunately it blew on the 14 heading to Mammoth Lakes and I wasn’t going to carry it for the duration of my trip. BFG wanted the tire to consider replacing under warranty.
glad someone else has one- spent the morning searching for the flare I have to no avail sorry Nimzero - My blowout on the other side was the only trouble I have ever had with the BFG's (it was E rated) still run them on my van, all my TJ Rubicons the FJ40 and D90 and have had great results over thousands of miles
