Ah, come on Scott!  You must be kidding!  Your torque wrench knows if it is
torquing a lubed or dry bolt and thus reads differently because?  BS!
If your wrench reads 100 '#, its 100'# applied to a wet noodle or a head
strong bolt.  Too much KY on hand, Scott?

Up to this point no one has proposed that the root problem is the backing
out of the bolts, at least not before the clamping force has been reduced to
zero by another active mechanism, creep of the aluminum wheel material.
Don't go out on this limb, Scott, until you have scribed a felt marker line
across the bolt head and wheel, such that you can check for bolt unwind
rotation just before you have to retorque.
