Interesting thread. I have had one blowout. My rig was only two years old, the tires had about 12,900 miles on them. Right front blew a 1 inch diameter hole in the sidewall. All other tires still in use and showing no adverse signs @ 25,000 miles. I have weighed the rig and I follow the tire mfg's pressure recommendations. I have quite a number of vehicles in service and blow outs, flats for that matter are a rarity. Pay just a little attention to your tires and they'll reward you.
