If you know your axle weights and LT tires can handle it that's fine but to make a blanket statement covering ALL LR E ST tires is wrong. My rig came with LR E Blowmaxs. I have 12,100 on the axles and I know it's heavier on the DS. If I replaced with your recommendation I would be at the max rating for the LT tires and probably over on the DS. It has 7k axles so I went with Sailuns.
