This week a set of Hall Ultra wheels sold on BaT for $2,500. I was following this auction and some folks were stating there were several well documented failures of these wheels. Does anyone have any concrete information on these failures? How did they happen? Were the wheels examined by a reputable lab to see if the failures actually occurred as a result of a defect in the wheels and their construction, or the metal used? Were XRF analysis of the metal done to see what alloy was used and its reliability under load and stress? X-ray done to detect gas holes or shrinkage cavities? Probably not done, but if examinations to that extent were completed, I would love to read about them. I have a set of Hall Ultra wheels (as I am sure many others on this forum have) and would really like to know the real documented and verified results of these "failures" versus anecdotal stories and conjectures. And no, mine have not failed, and have seen many high speed runs over the years.
P.S. Even the Air France's Concorde crash in 2000 was caused by a piece of metal that had fallen off another airplane and was run over by the Concorde's wheels during take-off, which in turn caused them to burst and set in motion a catastrophic chain of events.
