1968 C10, was home on lunch and went to head back to work. Left front was flat so I changed it out quick. Didn't get the lug nuts tight enough. Got about a half mile from where I was working, driving down a gravel road at about 40 mph and watched the wheel go into a corn field before the front hit the ground. Never had a wobble or anything, no warning at all. Be thankful they do give warning most times because there are odd occasions where they don't.
