Help! We just got home from a 176 mile (one way) trip and I was checking the lug tightness when I find 3 bolts loose, 1 sheared off and 1 missing completely, this is on a 99 Coleman Bayside (on the road side). These are new wheels and tires, original lug nuts. Could the lugs have been too loose? I tightened them by hand and then with a 4 way...tight...Sabotage? Ive NEVER seen this happen before. Notice two of the holes seem to be elongated, I'm now shopping for a new wheel, lug nuts and lug screws. I'm glad we made it home without an accident at highway speeds (never went over 65). I feel physically ill that my family could have been hurt. We are supposed to go away in 2 weeks again another 200 mile trip. Any solutions so this doesn't happen again?
