We were about an hour out when the first tire blew. One vehicle went back to Bowling Green, KY to buy another tire at Sam's. We made the repair and got down the road about another half hour and the second tire blew. Help came in the form of a KY roadside assistance truck--they were able to find a tire shop nearby that was open and had the right tires. We went ahead and replaced all the tires on the chuckwagon and continued our journey--about 5 1/2 hours behind schedule.
