I find that hard to believe.
Something was probably already snapped/cracked and driver didn't know it.
I always torque my own trailer wheels and when I get my vehicles done at Discount, I watch them do it and ask to see the torque wrench to verify the setting.
it starts with one or two, additional stress on the remainder and poof, they snap.
I've had sheared lugs on trucks and trailers when I had a hauling business. On the road sometimes 7 days a week for 11 years straight you see this often....on all types and sizes of trailers.
Myself and my drivers have found a loose trailer wheel with any combination of one or two sheard lugs with the remaining nuts loose or maybe a wheel with one loose nut and the other lugs and nuts gone......and all the lugs sheared off and a missing tire/wheel assy. Generally if the wheel can be found it can tell the story of what did and didn't happen.
These trucks and trailers tires/wheels/hubs were always pre trip inspected and checked any time the truck was shut down for fuel/rest/HOS/etc.
