We left on Thursday on this trip. On the way a tire on other side blew. We had to use the spare. Then on way home Yesterday the other tire went. Obviously we don't have 2 spare tires that is why we had no spare. As for tire conditions we replaced last year. It was 100 degrees yesterday. Things happen. We always have a spare on our camper. Unfortunately this time 2 tires were needed! As for good Sam update... Thank goodness we got someone on our own and didn't keep waiting. As of this morning still no call when they were coming! We would have spent night on side of road!
