And how is the wheel?

I had something similar happen with the camper I was towing last year; heard rumbling from the camper as we were rolling through the Chicago area in heavy traffic & thought it was a tire about to go. Got as far as Jolliet and stopped, found the wheel was down to two lug nuts, and the hole behind one of them was rounded out so badly that nut was doing nothing to hold the wheel on. Had to replace the hub and wheel (plus the cost of two hotel rooms so it was an expensive breakdown!)
