My Ford RV has these, and I blew out my rt. front tire on the way to AL for Thanksgiving. Limped in to Daughter in Laws house with a HUGE piece missing from the tread. Tried to change it out, but we broke a extension for the socket wrench. I stopped before we broke a hand or two. We will be taking it to a tire shop to get replaced next week when we go back down there. I’ll inquire about my nuts then.
