I always seem to forget that there is a whole range of AT tires that I don't consider all terrains, since they have paper thin sidewalls and belong on a vehicle that wont see anything more than a graded dirt road or maybe some snow over a graded road. I live in AZ where we have a lot of sharp rocks and I wheel a lot, so I only consider buying tires that have good sidewalls.
BFG all terrains were the first all terrain tires with good sidewalls that you could air down to 10psi, thats what set them apart way back when they were a new design. They filled a huge void in the market for people who use their truck for work and getting out on the weekends. Back in 2006 I was happy with bfg all terrains, had them on a silverado then on my 85 4runner for a few years. Most recently my wifes 04 4runner came with a new set when we bought it in 2015. I had been running cooper st maxx on my 80 since 2013, so I immediately noticed how bad the bfg's were in the snow by comparison. We put about 30k on the bfg's, then I bought some cooper st maxx for her truck. Those st maxx now have about 30k on them and are still quieter than the bfg's when I sold them and are still better in the snow than the bfg's were new. Cant knock the BFG tread life at all, they were still about 65% at 30k ish miles.
BFG's are overdue for a redesign, but BFG has no reason to since they have crazy brand loyalty and people keep buying them. Still not a bad tire by any means, but there are far better tires out in the last 3 or so years with better sidewalls, better traction in everything that BFG AT's suck at and have similar tread life with less noise.
For the OP, if you never air down or drive on rocks, you would probably be just fine with the thin sidewall AT's that weigh 10-15lbs less per tire than burlier tires. Going from 245/75/16 cooper at3's on my current silverado to the milestart patagonia xt's in 265/75/16 felt like I lost 60hp and 75 ftlbs of torque, the milestars weigh about 20lbs more and are a bit taller. Everything is a trade off, i'll pay the extra in gas and eat the loss in power for the comfort of not worrying about cutting a sidewall so much. But if you don't venture off of graded roads, the trade off of hauling around extra rotating mass might not be worth it. I put heavier falkens on my moms lx since she is physically unable to change a tire, so I don't have to worry so much about her hitting a curb and getting a pinch flat. That happened pretty frequently with the car she had before she entered the cruiser world.
