Many years ago Dad had a '64 Chev 3/4 ton that he used to haul a camper. It came with split rim, 8 hole wheels. He was going down a long hill at about 60 when a front wheel came off. He somehow, miraculously, kept it on the road, even with the big overshot camper on top.
The center of the wheel had torn out, leaving a jagged disk still tightly bolted to the hub. A week later, before he'd replaced the wheel, he got a recall letter from GM. He immediately went to the local Chev dealer and they installed 5 new wheels. Another week or so after that, he got a 2d letter saying they were only recalling the wheels that showed signed of failing. He didn't bother to return them.
BTW - for some unknown reason, the truck wasn't damaged other than a lot of scrapes on the hub. The brake, etc should have been trashed but it wasn't.
