Please double check your weights, weight distribution and pressures... Something just doesn't seem right there.
I checked axle weights on a certified CAT truck scale that day and the rear axle was 12,820. Later in the trip I encountered an unmanned weigh station scale in Idaho. I drove across 3 times (stopping for each weight to register properly) and checked right, left, and axle; rear axle weight was exactly the same at 12,820 and read 150lbs. different right to left.
In case anyone is wondering, the rear tires wear fine. There is no cupping, rivering, odd wear patterns, or premature wear, so it isn't an alignment problem (and yes, the alignment was checked at a heavy truck shop a while back).
Front tires I have no problem with; just the rears that heat up and increase dramatically in pressure.
