You guys are saying that the OP concern is known in the dually circle. I cannot contribute any experience as applied to DRW. I don't know if this applies or not, but I had a vehicle that was always wearing the left front tire. The vehicle was in perfect alignment, then one day I saw my wife pull into the driveway and I saw right away why the tire was wearing. My observation was that we were familiar with the turn into the driveway and as you know that turn into most peoples driveway is unlike turning in most intersections, its usually fairly sharp. Being accustomed to the turn we approached it to fast. I observed the tire as it took all the weight of the turn on that side of the car, particularly on the outer edge. I was surprised! I never imagined that much contortion and abuse was possible. It was a turn that the vehicle made at least once per day if not more. Armed with this knowledge we slowed down and took a wider turn and the wear problem went away. Perhaps this scenario is contributing to the OP problem. Let me add that my RAM 2500 4X4 wears the front tires but it wears them evenly. I rotate on a regular basis, in fact I need to rotate now as I have noticed that fronts are wearing, normally, but still wearing. Like I said I don't own a dually so can't contribute specifics on that subject.
