Same here. In over forty years of driving I have had only two tyres fail that I noticed while driving: one went flat over a period of a few seconds and the other was as you described, a pothole, I was only doing about 30 km per hour but the tyre was damaged beyond repair. In addition I've had a couple of slow leaks due to nails embedded in the tread but they were so slow that I didn't notice for days.
