Thanks for all your responses. I do have a tire blowout story of my own. We were driving in a rural part of New Mexico last year when we had an inside tire on our Winnebago class C blow out. An emergency roadside service tech came by, found us a tire, replaced it, and we were on our merry way. The next day on the interstate--boom!--lost the tire next to it. This time we used roadside assistance to find someone to replace it. Waited most of the day for the tire service to come and put on the new tire. Tire techs speculated the first tire that blew probably damaged the tire next to it. Other than that, we had no damage to our MH. We were either lucky or Winnebago makes a good product. When we got home we replaced all older tires.
