I had the same problem while in Wisconsin last year. It cost me 368 for a new tire to replace the one that blew out when a "technician" put too much air in it. Fortunately, I had a spare. When the new tire was installed the pro technician wrench-tightened each of my metal extensions. Now I check tire pressure every I drive, even if only around the block. So far, so good. I also carry a 200# pressure air compressor. A lesson well learned.
