Are you talking about the outer treads "cupping"? My '05 had the same problem with the stock BFG's. It was mostly my fault though because I didnt rotate the tires at all.
With my new set of tires I have solved the problem by cross-rotating about every 5,000 miles. I cross-rotate to help the tires wear evenly, but it can only be done with non-directional tread.
