I'm running 265-75/16 Michelin LTX M/S 'E' range on a Yukon XL, and will get over 100,000 miles on the tread life.
As far as I'm concerned, I will buy and install nothing but Michelin on the vehicles in my household. I've been in the auto industry for 25+ years, and have been on tire specific "hands-on" driving courses over the years and have seen the difference.
The LTX M/S is a bit less aggressive than the KO2 you're looking at, and frankly, I've been out of the loop on truck tires for several years, so I'm not sure what's out there now-a-days. But Michelin does make (I believe) a LTX A/T2, that should be comparable to the BFG you're looking at. Granted, I'm making assumptions at this point, but..... you get the point.
Good luck, have fun, and "truck on"!
