I have had BFG All/Terrain Radials on most of my 4x4 trucks for the last 25+ years. From stock sizes to 35s. In general they have performed well for my uses. A good compromise for mostly street and some off road. I have run across the occasional out of ballance tire that had to be replaced, but generally this showed up quickly and was replaced quickly.
I currently have TWO sets of BFG 315/70R/17 All/Terrain KOs. One set on stock alloy wheels and one set on stock chrome clad wheels. I have not had any problems with either of these sets of 315s. I have had both rotated and ballanced every 6000 miles. It does appear from all of the posts related to BFG 315 problems that maybe BFG has changed something in the makeup or manufacture of this particular tire. I assume that it was designed specifically for the H2 as a stock tire, somewhat like the BFG Rugged Trail for the Dodge.
I have 22,000 miles on the set I bought new. I bought a used set already mounted and ballanced on chrome wheels. These had about 8,000 miles. I have switched to the chrome wheel mounted set and swapped one of the original tires to a 5th chrome wheel for matching spare. I will go to 5 tire rotation when mileage is equal. The used set is as smooth as the new set I originally bought. I would guess that the posted problems are a very small segment of the overall number of tires in use. Just my experiences.
