I'm convinced that this happens mainly with the LR E tires (which have a stiffer carcass than LR D), when people put them on heavy vehicles, run them at highway speeds, at relatively low TP's. Plus the fact that old rubber just doesn't flex like when fresh out of the mold.
Besides that we don't know the history of these surplus tires. At the time when GL still used to sell these (by the hundreds of lots, each week) most of them came from HMMWVs which were cut up in pieces. Who knows for how long (maybe years) these vehicles had been standing stationary awaiting their fate, possibly even deflated some.
